  4. Air quality in inter-city buses : final report

    International Nuclear Information System (INIS)

    Various studies have suggested that air quality inside automobiles and school buses may be poorer than ambient or nearby air quality, and that concentrations of vehicle-related pollutants in city buses may be sufficiently elevated to pose concerns for vehicle occupants and operators. This paper presented the results of preliminary investigation of levels of some pollutants in inter-city buses to determine whether a fuller investigation is warranted. Another objective of the investigation was to develop methods for assessing air quality within road vehicles. Students carried monitoring equipment on 28 inter-city trips made by Greyhound Canada buses during July and August 2004. The equipment recorded average levels of carbon monoxide (CO) and nitrogen dioxide (NO2), as well as concentrations of particulate matter. Bus routes were selected that allowed for an average of 10 hours of total sampling time in a day. Data was recorded on pumps, run times and routes taken. Results indicated that levels of CO in the buses were much lower than the national standard of acceptable levels for CO. Levels of NO2 were on average lower, but 5 of the 19 recorded values exceeded acceptable levels. Average particulate levels recorded in the buses were considered acceptable, although some of the recorded levels were higher than desirable. It was concluded that further work on in-vehicle levels of NO2 and particulate matter could be warranted. Although several procedural and equipment problems were encountered, the methods used in the investigation appeared to be valid, and were thought to be suitable for further work on in-vehicle concentrations of pollutants. 21 refs

    Full Text Available The purpose of this paper was to present a reliability comparison of two types of city transport buses. Case study on the example of the well-known brands of city buses: Solaris Urbino 12 and Mercedes-Benz 628 Conecto L used at Municipal Transport Company in Lublin was presented in details. A reliability index for the most failure parts and complex systems for the period of time failures was determined. The analysis covered damages of the following systems: engine, electrical system, pneumatic system, brake system, driving system, central heating and air-conditioning and doors. Reliability was analyzed based on Weibull model. It has been demonstrated, that during the operation significant reliability differences occur between the buses produced nowadays.

  8. COMPARISON OF CLEAN DIESEL BUSES TO CNG BUSES

    Energy Technology Data Exchange (ETDEWEB)

    Lowell, D.; Parsley, W.; Bush,C; Zupo, D.

    2003-08-24

    Using previously published data on regulated and unregulated emissions, this paper will compare the environmental performance of current generation transit buses operated on compressed natural gas (CNG) to current generation transit buses operated on ultra low sulfur diesel fuel (ULSD) and incorporating diesel particulate filters (DPF). Unregulated emissions evaluated include toxic compounds associated with adverse health effects (carbonyl, PAH, NPAH, benzene) as well as PM particle count and size distribution. For all regulated and unregulated emissions, both technologies are shown to be comparable. DPF equipped diesel buses and CNG buses have virtually identical levels of PM mass emissions and particle number emissions. DPF-equipped diesel buses have lower HC and CO emissions and lower emissions of toxic substances such as benzene, carbonyls and PAHs than CNG buses. CNG buses have lower NOx emissions than DPF-equipped buses, though CNG bus NOx emissions are shown to be much more variable. In addition, this paper will compare the capital and operating costs of CNG and DPF-equipped buses. The cost comparison is primarily based on the experience of MTA New York City Transit in operating CNG buses since 1995 and DPF-equipped buses fueled with ULSD since 2001. Published data on the experience of other large transit agencies in operating CNG buses is used to validate the NYCT experience. The incremental cost (compared to ''baseline'' diesel) of operating a typical 200-bus depot is shown to be six times higher for CNG buses than for ''clean diesel'' buses. The contributors to this increased cost for CNG buses are almost equally split between increased capital costs for purchase of buses and installation of fueling infrastructure, and increased operating costs for purchase of fuel, bus maintenance, and fuel station maintenance.

    This report focuses on a gasoline-electric hybrid transit bus propulsion system. The propulsion system is an alternative to standard diesel buses and allows for reductions in emissions (usually focused on reductions of particulate matter and oxides of nitrogen) and petroleum use. Gasoline propulsion is an alternative to diesel fuel and hybrid propulsion allows for increased fuel economy, which ultimately results in reduced petroleum use.

  10. Diesel vs. compressed natural gas for school buses: a cost-effectiveness evaluation of alternative fuels

    International Nuclear Information System (INIS)

    Reducing emissions from school buses is a priority for both state and federal regulators. Two popular alternative technologies to conventional diesel (CD) are emission controlled diesel (ECD), defined here to be diesel buses equipped with continuously regenerating particle filters, and engines fueled by compressed natural gas (CNG). This paper uses a previously published model to quantify the impact of particulate matter (PM), oxides of nitrogen (NOx), and sulfur dioxide (SO2) emissions on population exposure to ozone and to primary and secondary PM, and to quantify the resulting health damages, expressed in terms of lost quality adjusted life years (QALYs). Resource costs include damages from greenhouse gas-induced climate change, vehicle procurement, infrastructure development, and operations. I find that ECD and CNG produce very similar reductions in health damages compared to CD, although CNG has a modest edge because it may have lower NOx emissions. However, ECD is far more cost effective ($400,000-900,000 cost per QALY saved) than CNG (around $4 million per QALY saved). The results are uncertain because the model used makes a series of simplifying assumptions and because emissions data and cost data for school buses are very limited

  11. Evaluation of retrofit crankcase ventilation controls and diesel oxidation catalysts for reducing air pollution in school buses

    2009-12-01

    This study evaluates the effect of retrofit closed crankcase ventilation filters (CCFs) and diesel oxidation catalysts (DOCs) on the in-cabin air quality in transit-style diesel school buses. In-cabin pollution levels were measured on three buses from the Pueblo, CO District 70 fleet. Monitoring was conducted while buses were driven along their regular routes, with each bus tested three times before and three times after installation of control devices. Ultrafine number concentrations in the school bus cabins were 33-41% lower, on average, after the control devices were installed. Mean mass concentrations of particulate matter less than 2.5 μm in diameter (PM2.5) were 56% lower, organic carbon (OC) 41% lower, elemental carbon (EC) 85% lower, and formaldehyde 32% lower after control devices were installed. While carbon monoxide concentrations were low in all tests, mean concentrations were higher after control devices were installed than in pre-retrofit tests. Reductions in number, OC, and formaldehyde concentrations were statistically significant, but reductions in PM2.5 mass were not. Even with control devices installed, during some runs PM2.5 and OC concentrations in the bus cabins were elevated compared to ambient concentrations observed in the area. OC concentrations inside the bus cabins ranged from 22 to 58 μg m -3 before and 13 to 33 μg m -3 after control devices were installed. OC concentrations were correlated with particle-bound organic tracers for lubricating oil emissions (hopanes) and diesel fuel and tailpipe emissions (polycyclic aromatic hydrocarbons (PAH) and aliphatic hydrocarbons). Mean concentrations of hopanes, PAH, and aliphatic hydrocarbons were lower by 37, 50, and 43%, respectively, after the control devices were installed, suggesting that both CCFs and DOCs were effective at reducing in-cabin OC concentrations.

    An environmental air quality of suspended particulate matter is insufficient in the big city area. To reduce the particulate matter, improvement of engine and development of the Diesel Particulate Filter (DPF) system are carrying. The purpose of this report is to investigate a possibility of practical use of the city buses installed DPF systems. From March 1995, investigation for practical use of these DPF systems on a route buses was carried in regular service operation of the Tokyo and Yokohama Transportation Bureau. The investigation items are service situation, smoke density and preparation inspection. From the result for 2 years service operation, each DPF systems needed some failure correspondence. but these were not fatal problem on using the DPF system. Then the subject of relative to durability and reliability became clear, and the performance of a low particulate emission DPF system obtained the high value evaluation for users. 9 refs., 4 figs., 2 tabs.

  14. Environmental benefits of natural gas for buses

    International Nuclear Information System (INIS)

    This paper presents a life cycle assessment comparing diesel buses with buses fueled by natural gas. The data for the emission of pollutants are based on the MEET Project of the European Commission (EC), supplemented by data measured for diesel and gas buses in Paris. The benefits of the gas fueled bus are then quantified using the damage cost estimates of the ExternE Project of the EC. A diesel bus with emissions equal to Standard EURO2 of the EC is compared with the same bus equipped with a natural gas engine, for use in Paris and in Toulouse. The damage cost of a diesel bus is significant, in the range of 0.4-1.3 euro/km. Natural gas allows an appreciable reduction of the emissions, lowering the damage cost by a factor of about 2.5 (Toulouse) to 5.5 (Paris). An approximate rule is provided for transferring the results to other cities. A sensitivity analysis is carried out to evaluate the effect of the evolution of the emissions standard towards EURO3, 4 and 5, as well as the effect of uncertainties. Finally a comparison is presented between a EURO2 diesel bus with particle filter, and a gas fueled bus with the MPI engine of IVECO, a more advanced and cleaner technology. With this engine the damage costs of the gas fueled bus are about 3-5 times lower than those of the diesel with particle filter, even though the latter has already very low emissions.(author)

    Evaluating the noise levels to which the bus drivers of Curitiba are exposed to during their working days is the main scope of this study. The city is served by an internationally known public transportation system featuring 1902 buses, which attend 1.9 million people per day. Two measurements have been taken inside each one of the 60 buses surveyed, one close to the driver and another one at the back of the bus. The results have showed that the dose levels the drivers are exposed to were below 50% in 92% out of the buses, but the normalized exposure levels were over 65 dB(A) in all cases. This level is considered as the threshold of comfort according to the Brazilian legislation on occupancy health NR-17--Ergonomics. The surveyed buses have been divided into three categories, according to their characteristics: feeder, rapid, and bi-articulated. A total of 20 buses within each category have been surveyed. Among the different categories, it has been found that the feeders have presented the highest noise levels. (To be presented in Portuguese.)

    In the area of management training, 'evaluation' refers both to the specific evaluation instrument used to determine whether a training effort was considered effective, and to the procedures followed to evaluate specific training requests. This report recommends to evaluate new training requests in the same way new procurement or new projects are evaluated. This includes examining training requests from the perspective of KSC goals and objectives, and determining expected ROI of proposed training program (does training result in improved productivity, through savings of time, improved outputs, and/or personnel reduction?). To determine whether a specific training course is effective, a statement of what constitutes 'good performance' is required. The user (NOT the Training Branch) must define what is 'required level of performance'. This 'model' will be the basis for the design and development of an objective, performance-based, training evaluation instrument.

  2. Transmission Loss Allocation Based on Buses Injected Currents

    Directory of Open Access Journals (Sweden)

    R.Aazami

    2011-09-01

    Full Text Available In this paper, a new method is proposed to allocate transmission loss in pool-based electricity markets. This method is based on using the impedance matrix of the network and the admittance equivalent circuit seen from the network buses. After performing load flow equations, the losses of each bus are calculated using the impedance matrix of the network and the reduced admittance matrix and the injected currents from each bus. These losses are properly and fairly shared between network buses for fair loss allocation in proportion to the percent of penetration the currents of each bus. Furthermore, using partial derivatives of the active power losses with respect to the bus currents’ coefficients, a sensitivity analysis has been done for proving the fairness of the proposed method. In addition to its simplicity, the suggested method assigns the losses properly and fairly between the buses. Finally, this method has been tested on a benchmark IEEE 14-bus network, and the results are compared with other existing methods.

  3. In-use fuel economy of hybrid-electric school buses in Iowa.

    2011-05-01

    Although it is much safer and more fuel-efficient to transport children to school in buses than in private vehicles, school buses in the United States still consume 822 million gal of diesel fuel annually, and school transportation costs can account for a significant portion of resource-constrained school district budgets. Additionally, children in diesel-powered school buses may be exposed to higher levels of particulates and other pollutants than children in cars. One solution to emission and fuel concerns is use of hybrid-electric school buses, which have the potential to reduce emissions and overall lifecycle costs compared with conventional diesel buses. Hybrid-electric technologies are available in the passenger vehicle market as well as the transit bus market and have a track record indicating fuel economy and emissions benefits. This paper summarizes the results of an in-use fuel economy evaluation for two plug-in hybrid school buses deployed in two different school districts in Iowa. Each school district selected a control bus with a route similar to that of the hybrid bus. Odometer readings, fuel consumption, and maintenance needs were recorded for each bus. The buses were deployed in 2008 and data were collected through May 2010. Fuel consumption was calculated for each school district. In Nevada, IA, the overall average fuel economy was 8.23 mpg for the hybrid and 6.35 mpg for the control bus. In Sigourney, IA, the overall average fuel economy was 8.94 mpg for the hybrid and 6.42 mpg for the control bus. The fuel consumption data were compared for the hybrid and control buses using a Wilcoxon signed rank test. Results indicate that fuel economy for the Nevada hybrid bus was 29.6% better than for the Nevada control bus, and fuel economy for the Sigourney hybrid bus was 39.2% higher than for the Sigourney control bus. Both differences were statistically significant. PMID:21608490

    Numerous laboratory studies report carbon monoxide, hydrocarbon, and particulate matter emission reductions with a slight nitrogen oxides emission increase from engines operating with biodiesel and biodiesel blends as compared to using petroleum diesel. We conducted a field study on a fleet of school buses to evaluate the effects of biodiesel use on gaseous and particulate matter fuel-based emission factors under real-world conditions. The field experiment was carried out in two phases during winter 2004. In January (phase I), emissions from approximately 200 school buses operating on petroleum diesel were measured. Immediately after the end of the first phase measurement period, the buses were switched to a 20% biodiesel blend. Emission factors were measured again in March 2004 (phase II) and compared with the January emission factors. To measure gaseous emission factors we used a commercial gaseous remote sensor. Particulate matter emission factors were determined with a combination of the gaseous remote sensor, a Lidar (light detection and ranging), and transmissometer system developed at the Desert Research Institute of Reno, NV, U.S.A. Particulate matter emissions from school buses significantly increased (up to a factor of 1.8) after the switch from petroleum diesel to a 20% biodiesel blend. The fuel used during this campaign was provided by a local distributor and was independently analyzed at the end of the on-road experiment. The analysis found high concentrations of free glycerin and reduced flash points in the B 100 parent fuel. Both measures indicate improper separation and processing of the biodiesel product during production. The biodiesel fuels used in the school buses were not in compliance with the U.S.A. ASTM D6751 biodiesel standard that was finalized in December of 2001. The U.S.A. National Biodiesel Board has formed a voluntary National Biodiesel Accreditation Program for producers and marketers of biodiesel to ensure product quality and

    This Oil Bypass Filter Technology Evaluation final report documents the feasibility of using oil bypass filters on 17 vehicles in the Idaho National Laboratory (INL) fleet during a 3-year test period. Almost 1.3 million test miles were accumulated, with eleven 4-cycle diesel engine buses accumulating 982,548 test miles and six gasoline-engine Chevrolet Tahoes accumulating 303,172 test miles. Two hundred and forty oil samples, taken at each 12,000-mile bus servicing event and at 3,000 miles for the Tahoes, documented the condition of the engine oils for continued service. Twenty-eight variables were normally tested, including the presence of desired additives and undesired wear metals such as iron and chrome, as well as soot, water, glycol, and fuel. Depending on the assumptions employed, the INL found that oil bypass filter systems for diesel engine buses have a positive payback between 72,000 and 144,000 miles. For the Tahoes, the positive payback was between 66,000 and 69,000 miles.

    The scope of this study was to evaluate risk factors for cardiovascular disease among bus drivers in Montes Claros in the state of Minas Gerais. A semi-structured questionnaire covering personal, anthropometric, professional and labor-related data was used, in addition to a questionnaire on the level of stress. 53 bus drivers were surveyed and the average age was 30 to 39 years of age. 81.1% were non-smokers; 58% of the sample were teetotalers; and 50% took regular exercise. In the assessment of BMI, 40 drivers (75.4%) were overweight. The prevalence in eating habits revealed excess consumption of sugar (66.0%), fat (64.2%), coffee (69.8%), salt (60.4%), coca cola (64.2%) and soft drinks (54.7%). Among reports of chronic diseases, no diabetic (98.1%) or hypertensive (94.3%) drivers were observed. Most of the sample (69.7%) had normal stress levels. With respect to laboratory data, the vast majority of drivers had hypertriglyceridemia and hypercholesterolemia. HDL levels were satisfactory, and the LDL revealed normal and desirable levels in more than half of the sample. The prevalence of cardiovascular disease was low. PMID:22899155

    On July 5, 1979, DOE promulgated final regulations of the Emergency Building Temperature Restrictions program, placing emergency restrictions on thermostat settings for space heating, space cooling, and hot water in commercial, industrial, and nonresidential public buildings. The final regulations restricted space heating to a maximum of 65/sup 0/F, hot water temperature to a maximum of 105/sup 0/F, and cooling temperature to a minimum of 78/sup 0/F. A comprehensive evaluation of the entire EBTF program for a nine-month period from July 16, 1979 is presented. In Chapter 1, an estimate of the population of buildings covered by EBTR is presented.

    Full Text Available Background and Objective: Road transportation and specifically bus travel accounts for the bulk of travel. Contaminated drinking water consumption is one of the issues that threaten health, and always there is pollution possibility in drinking water in buses. This study evaluated the microbial quality of consumed drinking water in buses and also compared it with available standards. Materials and Methods: This study is a cross-sectional study. By considering similar studies, 95% confidence interval and based on the samples size formula for tradition of proportion, 80 buses from 122 buses that entered Bushehr Passenger Depot from other cities or exited it were randomly selected. Over a three-month period, samples were taken from drinking water in these buses. Temperature, pH, residual chlorine, total coliform (TC, and fecal coliform (E. coli in each sample were measured in accordance with the standard method. Statistical analysis of the data was carried out with SPSS Version 16, and the t-test was performed for statistical difference. Results: The results showed that residual chlorine in 97.5% was zero and pH values of the samples were in the range of 6.8-8.7. TC and E. coli numbers in 12.5% and 8.8% of the samples were higher than those of standards, respectively. Conclusion: Use of ice, washing time of the drinking water tank (daily or weekly, and method of usage and storage of drinking water (with 20-liter tanks had significant effects on the bacterial loads of the drinking water in the tanks (p value <0.05. Some factors such as tank material, driver's education and age, type and model of the bus, filling time of the tank (daily or weekly, the method of filling and emptying the tank (complete clearing out of the tank or otherwise, and distance had no significant effect on the quality of the drinking water in the buses.

  15. Carbon Dioxide Concentrations and Temperatures within Tour Buses under Real-Time Traffic Conditions.

    Directory of Open Access Journals (Sweden)

    Chun-Fu Chiu

    Full Text Available This study monitored the carbon dioxide (CO2 concentrations and temperatures of three 43-seat tour buses with high-passenger capacities in a course of a three-day, two-night school excursion. Results showed that both driver zones and passenger zones of the tour buses achieved maximum CO2 concentrations of more than 3000 ppm, and maximum daily average concentrations of 2510.6 and 2646.9 ppm, respectively. The findings confirmed that the CO2 concentrations detected in the tour buses exceeded the indoor air quality standard of Taiwan Environmental Protection Administration (8 hr-CO2: 1000 ppm and the air quality guideline of Hong Kong Environmental Protection Department (1 hr-CO2: 2500 ppm for Level 1 for buses. Observations also showed that high-capacity tour bus cabins with air conditioning system operating in recirculation mode are severely lacking in air exchange rate, which may negatively impact transportation safety. Moreover, the passenger zones were able to maintain a temperature of between 20 and 25°C during travel, which effectively suppresses the dispersion of volatile organic compounds. Finally, the authors suggest that in the journey, increasing the ventilation frequency of tour bus cabin, which is very beneficial to maintain the travel safety and enhance the quality of travel.

  16. Conceptual Design of the TPF-O SC Buses

    2007-01-01

    The Terrestrial Planet Finder - Occulter (TPF-O) mission has two Spacecraft (SC) buses, one for a space telescope and the other for a formation-flying occulter. SC buses typically supply the utilities (support structures, propulsion, attitude control, power, communications, etc) required by the payloads. Unique requirements for the occulter SC bus are to provide the large delta V required for the slewing maneuvers of the occulter, and comunications for formation flying. The TPF-O telescope SC bus shares some key features of the one for the Hubble Space Telescope (HST): both support space telescopes designed to observe in the visible to near infrared range of wavelengths with comparable primary mirror apertures (2.4 m for HST, 2.4 - 4.0 m for TPF-O). However, TPF-O is expected to have a Wide Field Camera (WFC) with a Field of View (FOV) much larger than that of HST. Ths WFC is also expected to provide fine guidance. TPF-O is designed to operate in an orbit around the Sun-Earth Lagrange 2 (SEL2) point. The longer communications range to SEL2 and the large science FOV require higher performance communications than HST. Maintaining a SEL2 orbit requires TPF-O, unlike HST, to have a propulsion system. The velocity required for reachng SEL2 and the limited capabilities of affordable launch vehicles require both TPF-O elements to have compact, low-mass designs. Finally, it is possible that TPF-O may utilize a modular design derived fiom that of HST to allow servicing in the SEL2 orbit.

    2015-09-01

    Battery Electric Bus (BEB) has become one of prior options of urban buses for its "zero emission" during the driving stage. However, the environmental performance of electric buses is affected by multi-factors from the point of whole life cycle. In practice, carrying capacity of BEB and power generation structures can both implement evident effects on the energy consumption and pollutants emission of BEB. Therefore, take the above factors into consideration, in this article, Life Cycle Assessment is employed to evaluate the energy conservation and emissions reduction benefits of BEB. Results indicate that, travel service is more reasonable as the functional unit, rather than mileage, since the carrying capacity of BEB is 15% lower than the diesel buses. Moreover, compared with diesel buses, the energy conservation and emissions reduction benefits of battery electric buses are all different due to different regional power structures. Specifically, the energy benefits are 7. 84%, 11. 91%, 26. 90%, 11. 15%, 19. 55% and 20. 31% respectively in Huabei, Huadong, Huazhong, Dongbei, Xibei and Nanfang power structure. From the point of comprehensive emissions reduction benefits, there is no benefit in Huabei power structure, as it depends heavily on coal. But in other areas, the comprehensive emissions reduction benefits of BEB are separately 3. 46%, 26. 81%, 1. 17%, 13. 74% and 17. 48% in Huadong, Huazhong, Dongbei, Xibei and Nanfang. Therefore, it suggests that, enlargement of carrying capacity should be taken as the most prior technology innovation direction for BEB, and the grids power structure should be taken into consideration when the development of BEB is in planning.

  20. Comparison of Life Cycle energy consumption and GHG emissions of natural gas, biodiesel and diesel buses of the Madrid transportation system

    International Nuclear Information System (INIS)

    This paper presents a comparative study on the use of three after-treatment technologies: i) EGR + DPF, ii) SCR + Urea and iii) 3-way catalyst when implemented in urban buses, to determinate the energy requirements, greenhouse gas emissions (GHG), direct Land Use Change (dLUC), abiotic depletion of fossil energy by means of a Life Cycle Assessment (LCA). The process of production, conditioning and transporting of the fuels used by the buses (diesel, biodiesel (B100), a blended biodiesel at 20% (B20) and natural gas) were also analyzed (Well-to-Tank analysis) along with the environmental impact due to its combustion in the bus (Tank-to-Wheel analysis). The environmental impact of the manufacturing, maintenance and recycling process of the urban buses and exhaust after-treatment systems has also been evaluated. Main results shows that Life Cycle of SCR + Urea technology reduces environmental impact to a greater extent than its global Life Cycle increases it when gasoil is used resulting in a final balance more efficient than the other options, the same behavior is observed with the use of B20 and B100 but only when 0%dLUC is assumed since if the percentage of dLUC increases the effectiveness of the SCR + Urea technology in the reduction of environmental impact tend to decrease. -- Highlights: ► We examine the environmental impact caused by the Life Cycle of each technology, fossil fuel, biofuel and vehicle. ► Biodiesel environmental impact depends largely on land transformed for grow crops. ► Using SCR + Urea technology and gasoil as a fuel in the bus further reduces the environmental impact.

  7. Woodstove exchange program : pilot evaluation : final report

    International Nuclear Information System (INIS)

    The Government of British Columbia launched a woodstove exchange program to instigate the replacement of old or uncertified woodstoves with high efficiency Canadian Standards Association B415 or United States Environmental Protection Agency (EPA) emissions-certified, clean-burning appliances. The initiative ran as a three-year pilot program focusing on the Highway 16 corridor of the Skeena region between Terrace and Burns Lake in British Columbia. A similar program has also been operating in the Cariboo and other regions. The program included an evaluation component, whose objectives were to guide the development of a provincial strategy for woodstove exchange, while improving on the pilot, and to develop an appropriate evaluation template that could be successfully applied to future exchange programs in Canada and the United States. The primary research component of the evaluation consisted of three separate public opinion surveys, including a consumer awareness survey, a participant survey, and a non-participant survey. This report presented a detailed analysis of the results of all three surveys. Results that were discussed for the consumer awareness survey included perceptions of local air quality; ownership of wood-burning appliances; awareness of and participation in the woodstove exchange program; likelihood of future participation in the woodstove exchange program; burn-it smart workshops; and perceptions of by-laws applicable to woodstoves. Similar topics were discussed in the other two surveys. Recommendations were also offered. It was concluded that although local air quality was generally rated as good, a significant number of respondents had some concerns about air pollution and saw wood burning as a source of air pollution. tabs., figs., appendices

    Giordano Spadacini

    2015-01-01

    Full Text Available This work reports a modeling methodology for the prediction of conducted emissions (CE in a wide frequency range (up to 100 MHz, which are generated by dc/dc converters and propagate along the power buses of satellites. In particular, the dc/dc converter seen as a source of CE is represented by a behavioral model, whose parameters can be identified by two unit-level experimental procedures performed in controlled test setups. A simplified multiconductor transmission-line (MTL model is developed to account for the propagation of CE in shielded bundles of twisted-wire pairs used as power cables. The whole power system is represented by the interconnection of the circuit models of dc/dc converters, cables, and Power Conditioning and Distribution Unit (PCDU. By solving the obtained network, frequency spectra of CE can be predicted. Experimental results are reported to substantiate the accuracy of the proposed unit-level dc/dc converter model and the MTL model of cables. Finally, a system-level test setup composed of three dc/dc converters connected to a PCDU is considered, and predicted CE are compared versus experimental measurements.

  10. Waste Form Evaluation Program. Final report

    International Nuclear Information System (INIS)

    This report presents data that can be used to assess the acceptability of polyethylene and modified sulfur cement waste forms to meet the requirements of 10 CFR 61. The waste streams selected for this study include dry evaporator concentrate salts and incinerator ash as representative wastes which result from advanced volume reduction technologies and ion exchange resins which remain problematic for solidification using commercially available matrix materials. Property evaluation tests such as compressive strength, water immersion, thermal cycling, irradiation, biodegradation and leachability were conducted for polyethylene and sulfur cement waste forms over a range of waste-to-binder ratios. Based on the results of the tests, optimal waste loadings of 70 wt % sodium sulfate, 50 wt % boric acid, 40 wt % incinerator ash and 30 wt % ion exchange resins were established for polyethylene, although maximum loadings were considerably higher. For modified sulfur cement, optimal loadings of 40 wt % sodium sulfate, 40 wt % boric acid and 40 wt % incinerator ash are reported. Ion exchange resins are not recommended for incorporation into modified sulfur cement because of poor waste form performance even at very low waste concentrations. The results indicate that all waste forms tested within the range of optimal waste concentrations satisifed the requirements of the NRC Technical Position Paper on Waste Form

  11. Nuclear fuel performance evaluation. Final report

    International Nuclear Information System (INIS)

    An evaluation has been made of the ability of Scandpower's empirical fuel performance model POSHO (''Power Shock'') to predict the probability of fuel pin failures resulting from pellet-clad interaction in commercial nuclear power plants. POSHO provides an analytical method to calculate the failure probabilities associated with power level maneuvers for different fuel assembly designs. Application of the method provides a basis for risk-benefit decisions concerning operational procedures, fuel designs and fuel management strategies. One boiling water reactor (BWR) and one pressurized water reactor (PWR) were selected for study to compare model predictions with actual failures, as determined from post irradiation examination of the fuel and activity release data. The fuel duty cycles were reconstructed from operating records and nodal power histories were created by using Scandpower's FMS computer programs. Nodal power histories, coupled with the relative pin power distribution in each node, were processed by the fuel failure prediction model, which tracks the interaction power level for each pin group in each node and calculates the power shocks and the probability for pellet-clad interaction cracks. The results of these calculations are processed statistically to give the expected number of cracks, the number of failed fuel pins in each assembly and the total number of failed assemblies in the core. Fuel performance in the BWR, Quad Cities Unit Two, was calculated by the model in approximate agreement with the observed performance. Fuel performance in the PWR, Maine Yankee, was calculated in approximate agreement for two of the three fuel designs. The high failure rate in the third design, Type B fuel, was not calculated by the POSHO pellet-clad interaction model

    2007-08-01

    In 2005 the National Ground Intelligence Center (NGIC) proposed that the PATTON Alliance provide assistance in evaluating and obtaining the Integrated Gazetteer Database (IGDB), developed for the Naval Space Warfare Command Research group (SPAWAR) under Advance Research and Development Activity (ARDA) funds by MITRE Inc., fielded to the text-based search tool GeoLocator, currently in use by NGIC. We met with the developers of GeoLocator and identified their requirements for a better gazetteer. We then validated those requirements by reviewing the technical literature, meeting with other members of the intelligence community (IC), and talking with both the United States Geologic Survey (USGS) and the National Geospatial Intelligence Agency (NGA), the authoritative sources for official geographic name information. We thus identified 12 high-level requirements from users and the broader intelligence community. The IGDB satisfies many of these requirements. We identified gaps and proposed ways of closing these gaps. Three important needs have not been addressed but are critical future needs for the broader intelligence community. These needs include standardization of gazetteer data, a web feature service for gazetteer information that is maintained by NGA and USGS but accessible to users, and a common forum that brings together IC stakeholders and federal agency representatives to provide input to these activities over the next several years. Establishing a robust gazetteer web feature service that is available to all IC users may go a long way toward resolving the gazetteer needs within the IC. Without a common forum to provide input and feedback, community adoption may take significantly longer than anticipated with resulting risks to the war fighter.

  13. Comparative study of the work load between one-man buses and two-man buses.

    Ueno,Mitsuo

    1985-06-01

    Full Text Available The differences in physiological and safety conditions of one-man buses and two-man buses were examined from the view point of occupational fatigue. This survey consisted of a work load study which included a time study, study of subsidiary behavior, auditory task, memory test, Galvanic Skin Response (GSR and physiological function tests and a self-administered questionnaire which involved items concerning safety and subjective fatigue complaints. The visual and postural restrictions in the one-man bus were greater than in the two-man bus. The mental capacity of the one-man bus drivers was found to be less. Greater mental fatigue and stress were observed in the one-man bus. More subjective fatigue complaints were observed in the one-man bus. More cases of near accidents were observed in the one-man bus. From these results it was concluded that the one-man bus caused bus drivers a greater mental and physical work load.

    In this study size-resolved particle and gaseous emissions from 28 individual diesel-fuelled and 7 compressed natural gas (CNG)-fuelled buses, selected from an in-use bus fleet, were characterised for real-world dilution scenarios. The method used was based on using CO2 as a tracer of exhaust gas dilution. The particles were sampled by using an extractive sampling method and analysed with high time resolution instrumentation EEPS (10 Hz) and CO2 with a non-dispersive infrared gas analyser (LI-840, LI-COR Inc. 1 Hz). The gaseous constituents (CO, HC and NO) were measured by using a remote sensing device (AccuScan RSD 3000, Environmental System Products Inc.). Nitrogen oxides, NOx, were estimated from NO by using default NO2/NOx ratios from the road vehicle emission model HBEFA3.1. The buses studied were diesel-fuelled Euro III-V and CNG-fuelled Enhanced Environmentally Friendly Vehicles (EEVs) with different after-treatment, including selective catalytic reduction (SCR), exhaust gas recirculation (EGR) and with and without diesel particulate filter (DPF). The primary driving mode applied in this study was accelerating mode. However, regarding the particle emissions also a constant speed mode was analysed. The investigated CNG buses emitted on average a higher number of particles but less mass compared to the diesel-fuelled buses. Emission factors for number of particles (EFPN) were EFPN, DPF = 4.4 ± 3.5 × 1014, EFPN, no DPF = 2.1 ± 1.0 × 1015 and EFPN, CNG = 7.8 ± 5.7 ×1015 kg fuel-1. In the accelerating mode, size-resolved emission factors (EFs) showed unimodal number size distributions with peak diameters of 70-90 nm and 10 nm for diesel and CNG buses, respectively. For the constant speed mode, bimodal average number size distributions were obtained for the diesel buses with peak modes of ~10 nm and ~60 nm. Emission factors for NOx expressed as NO2 equivalents for the diesel buses were on average 27 ± 7 g (kg fuel)-1 and for the CNG buses 41 ± 26 g (kg

    In the United Sates, more than 80% of transit city buses are air conditioned. Vapor compression refrigeration systems are standard for air conditioning buses and account for up to 25% of fuel consumption in the cooling season. Vapor compression devices use chlorofluorocarbons (CFCs), chemicals that contributes to Earths`s ozone depletion and to global warming. Currently, evaporative cooling is an economical alternative to CFC vapor compression refrigeration for air conditioning buses. It does not use CFCs but is restricted in use to arid climates. This limitation can be eliminated by dehumidifying the supply air using desiccants. We studied desiccant systems for cooling transit buses and found that the use of a desiccant-assisted evaporative cooling system is feasible and can deliver the required cooling. The weight and the size of the desiccant system though larger than vapor compression systems, can be easily accommodated within a bus. Fuel consumption for naming desiccant systems was about 70% less than CFC refrigeration system, resulting in payback periods of less than 2.5 years under most circumstances. This preliminary study indicated that desiccant systems combined with evaporative cooling is a CFC-free option to vapor compression refrigeration for air conditioning of transit buses. The concept is ready to be tested in a fun prototype scale in a commercial bus.

  1. Towards sustainable urban transportation: Test, demonstration and development of fuel cell and hybrid-electric buses

    International Nuclear Information System (INIS)

    Several aspects make today's transport system non-sustainable: - Production, transport and combustion of fossil fuels lead to global and local environmental problems. - Oil dependency in the transport sector may lead to economical and political instability. - Air pollution, noise, congestion and land-use may jeopardise public health and quality of life, especially in urban areas. In a sustainable urban transport system most trips are made with public transport because high convenience and comfort makes travelling with public transport attractive. In terms of emissions, including noise, the vehicles are environmentally sustainable, locally as well as globally. Vehicles are energy-efficient and the primary energy stems from renewable sources. Costs are reasonable for all involved, from passengers, bus operators and transport authorities to vehicle manufacturers. The system is thus commercially viable on its own merits. This thesis presents the results from three projects involving different concept buses, all with different powertrains. The first two projects included technical evaluations, including tests, of two different fuel cell buses. The third project focussed on development of a series hybrid-bus with internal combustion engine intended for production around 2010. The research on the fuel cell buses included evaluations of the energy efficiency improvement potential using energy mapping and vehicle simulations. Attitudes to hydrogen fuel cell buses among passengers, bus drivers and bus operators were investigated. Safety aspects of hydrogen as a vehicle fuel were analysed and the use of hydrogen compared to electrical energy storage were also investigated. One main conclusion is that a city bus should be considered as one energy system, because auxiliaries contribute largely to the energy use. Focussing only on the powertrain is not sufficient. The importance of mitigating losses far down an energy conversion chain is emphasised. The Scania hybrid fuel cell

    This study evaluated the costs and benefits associated with the use of stationary-wireless-power-transfer-enabled plug-in hybrid electric buses and determined the cost effectiveness relative to conventional buses and hybrid electric buses. A factorial design was performed over a number of different battery sizes, charging power levels, and f bus stop charging stations. The net present costs were calculated for each vehicle design and provided the basis for design evaluation. In all cases, given the assumed economic conditions, the conventional bus achieved the lowest net present cost while the optimal plug-in hybrid electric bus scenario beat out the hybrid electric comparison scenario. The parameter sensitivity was also investigated under favorable and unfavorable market penetration assumptions.

    Full Text Available In this study size-resolved particle and gaseous emissions from 28 individual diesel-fuelled and 7 compressed natural gas (CNG-fuelled buses, selected from an in-use bus fleet, were characterised for real-world dilution scenarios. The method used was based on using CO2 as a tracer of exhaust gas dilution. The particles were sampled by using an extractive sampling method and analysed with high time resolution instrumentation EEPS (10 Hz and CO2 with non-dispersive infrared gas analyser (LI-840, LI-COR Inc. 1 Hz. The gaseous constituents (CO, HC and NO were measured by using a remote sensing device (AccuScan RSD 3000, Environmental System Products Inc.. Nitrogen oxides, NOx, were estimated from NO by using default NO2/NOx ratios from the road vehicle emission model HBEFA 3.1. The buses studied were diesel-fuelled Euro II–V and CNG-fuelled Enhanced Environmental Friendly Vehicles (EEVs with different after-treatment, including selective catalytic reduction (SCR, exhaust gas recirculation (EGR and with and without diesel particulate filter (DPF. The primary driving mode applied in this study was accelerating mode. However, regarding the particle emissions also a constant speed mode was analysed. The investigated CNG buses emitted on average higher number of particles but less mass compared to the diesel-fuelled buses. Emission factors for number of particles (EFPN were EFPN, DPF = 8.0 ± 3.1 × 1014, EFPN, no DPF =2.8 ± 1.6 × 1015 and EFPN, CNG = 7.8 ± 5.7 × 1015 (kg fuel−1. In the accelerating mode size-resolved EFs showed unimodal number size distributions with peak diameters of 70–90 nm and 10 nm for diesel and CNG buses, respectively. For the constant speed mode bimodal average number size distributions were obtained for the diesel buses with peak modes of ~10 nm and ~60 nm.

  11. Comparative evaluation of radioactive waste management options. Final report

    International Nuclear Information System (INIS)

    A comprehensive presentation of the various radioactive waste options under debate has not been made so far, let alone a comparative evaluation of the options with respect to their substantiated or assumed advantages or drawbacks. However, any appropriate discussion about the pros and cons of the specific options for final decision making has to be based on a comprehensive knowledge base drawn from profound comparative evaluation of essential options. Therefore, the study reported in this publication was to serve three major purposes: Presentation of the conditions and waste management policies and approaches in selected countries, in order to compile information about the various policy goals and the full scope of argumentation, as well as the range of individual arguments used for or against specific options. - Derivation of a methodology for evaluation, including development of criteria for a comparative and qualitative evaluation of options. - Identification of possible implications for a waste management strategy for Germany, derived from the results of the comparative evaluation and the examination of the reasonings and argumentation used in the various countries.

    In 1990, the U.S. Department of Energy (DOE) sponsored a comprehensive evaluation of its Weatherization Assistance Program, the nation`s largest residential energy conservation program. Oak Ridge National Laboratory (ORNL) managed the five-part study. This document summarizes the findings of the evaluation. Its conclusions are based mainly on data from the 1989 program year (supplemented by data from 1991-92). The evaluation concludes that the Program meets the objectives of its enabling legislation and fulfills its mission statement. Specifically, it (1) saves energy, (2) lowers fuel bills, and (3) improves the health and safety of dwellings occupied by low-income people. In addition, the Program achieves its mission in a cost-effective manner based on each of three perspectives employed by the evaluators. Finally, the evaluation estimates that the investments made in 1989 will, over a 20-year lifetime, save the equivalent of 12 million barrels of oil, roughly the amount of oil added to the Strategic Petroleum Reserve in each of the past several years.

  14. Overview about the environmental analysis within the project CUTE : Clean urban transport for Europe using fuel cell driven buses

    International Nuclear Information System (INIS)

    Established to demonstrate the readiness of the fuel cell technology as an almost emission-free and low-noise transport system in public transportation, the Clean Urban Transport for Europe (CUTE) represents the first large scale fleet application of fuel cell driven vehicles. The firm IKP is responsible for the evaluation of new technology concerning fuel cell driven buses in its entirety and over its complete life cycle, to ensure that the goals of environmentally friendly and resource saving of transportation are achieved. A comparison with conventional alternatives, such as diesel driven buses, and compressed natural gas buses was performed. Life cycle assessment in accordance with Deutsches Institut fur Normung e.V. (DIN) International Standardization Organization (ISO) 14040 series was used for the ecological, technical and economic analysis. The potential of the new fuel cell technology in the reduction of air polluting emissions such as sulphur dioxide and summer smog causing nitrogen oxides in highly populated inner city areas was investigated, along with the quantification of the abatement of carbon dioxide at European level and contribution to Kyoto commitments. 7 refs., 8 figs

The Program's mission is to reduce the heating and cooling costs for low-income families--particularly the elderly, persons with disabilities, and children by improving the energy efficiency of their homes and ensuring their health and safety. Substantial progress has been made, but the job is far from over. The Department of Health and Human Services (HHS) reports that the average low-income family spends 12 percent of its income on residential energy, compared to only 3% for the average-income family. Homes where low-income families live also have a greater need for energy efficiency improvements, but less money to pay for them.

    On October 2004, a sampling survey was carried out in Florence to estimate urban fine particle exposure concentrations inside commuting vehicles during workdays characterized by heavy traffic. Portable samplers were positioned inside four regularly scheduled diesel-powered buses and four taxis during eight weekdays. Each sampler consisted of a 2.5 μm size pre-separator cyclone, a direct-reading data logging photometer (pDR-1200), and a 4 L min -1 filter sampler for the determination of PM 2.5 mass concentration. Based on reflectance analysis measurements, a PM 2.5 Black Smoke Index was determined for each filter, and the elemental composition of the PM 2.5 was analyzed by Particle Induced X-ray Emission (PIXE). PM 2.5 mass concentrations inside the vehicles correlated well with the urban ambient air PM 2.5 concentrations measured at the fixed-site monitoring stations. The PM 2.5 excess above the urban ambient level was on average 32 μg m -3 (range: 22-52 μg m -3) and 20 μg m -3 (range: 11-29 μg m -3) in buses and taxis, respectively. The PM 2.5-bound sulfur concentration was also higher in the buses than in the taxis. Based on daily Time-Microenvironment-Activity-Diary (TMAD) data, the Florentines spend on average 9.7% of their day in traffic, and the corresponding average exposure is approximately 12% of their daily PM 2.5 personal exposure. The obtained data could be used to plan interventions to minimize the PM 2.5 citizen exposures in commuting.

    Mario A. Rios

    2014-08-01

    Full Text Available This study proposes a general procedure to compute the load demand profile from a parking lot where a fleet of buses with electric propulsion mechanisms are charged. Such procedure is divided in three different stages, the first one models the daily energy utilisation of the batteries based on Monte Carlo simulations and route characteristics. The second one models the process in the charging station based on discrete event simulation of queues of buses served by a lot of available chargers. The third step computes the final demand profile in the parking lot because of the charging process based on the power consumption of batteries’ chargers and the utilisation of the available charges. The proposed procedure allows the computation of the number of required batteries’ chargers to be installed in a charging station placed at a parking lot in order to satisfy and ensure the operation of the fleet, the computation of the power demand profile and the peak load and the computation of the general characteristics of electrical infrastructure to supply the power to the station.

  9. Quantitative characterization of the reliability of simplex buses and stars to compare their benefits in fieldbuses

    International Nuclear Information System (INIS)

    Fieldbuses targeted to highly dependable distributed embedded systems are shifting from bus to star topologies. Surprisingly, despite the efforts into this direction, engineers lack of analyses that quantitatively characterize the system reliability achievable by buses and stars. Thus, to guide engineers in developing adequate bus and star fieldbuses, this work models, quantifies and compares the system reliability provided by simplex buses and stars for the case of the Controller Area Network (CAN). It clarifies how relevant dependability-related aspects affect reliability, refuting some intuitive ideas, and revealing some previously unknown bus and star benefits. - Highlights: • SANs models that quantify the reliability of simplex buses/stars in fieldbuses. • Models cover system relevant dependability-related features abstracted in the literature. • Results refute intuitive ideas about buses and stars and show some unexpected effects. • Models and results can guide the design of reliable simplex bus/stars fieldbuses

    2011-01-01

    On-road emission and fuel consumption (FC) levels for Euro Ⅲ and Ⅳ buses fueled on diesel and compressed natural gas (CNG)were compared, and emission and FC characteristics of buses were analyzed based on approximately 28,700 groups of instantaneous data obtained in Beijing using a portable emissions measurement system (PEMS). The experimental results revealed that NOx and PM emissions from CNG buses were decreased by 72.0% and 82.3% respectively, compared with Euro Ⅳ diesel buses. Similarly,these emissions were reduced by 75.2% and 96.3% respectively, compared with Euro Ⅲ diesel buses. In addition, CO2, CO, HC,NOx, PM emissions and FC of Euro Ⅳ diesel buses were reduced by 26.4%, 75.2%, 73.6%, 11.4%, 79.1%, and 26.0%, respectively,relative to Euro Ⅲ diesel buses. The CO2, CO, HC, NOx, PM emissions and FC factors all decreased with bus speed increased, while increased as bus acceleration increased. At the same time, the emission/FC rates as well as the emission/FC factors exhibited a strong positive correlation with the vehicle specific power (VSP). They all were the lowest when VSP < 0, and then rapidly increased as VSP increased. Furthermore, both the emission/FC rates and emission/FC factors were the highest at accelerations, higher at cruise speeds,and the lowest at decelerations for non-idling buses. These results can provide a base reference to further estimate bus emission and FC inventories in Beijing.

    Cool science is an art contest where K12 students create placards (7" x 22") to educate the public about climate change. Students are prompted to create their artwork in response to questions such as: What is the evidence for climate change? How does climate change impact your local community? What can you do to reduce the impacts of climate change? In each of three years, 500-600 student entrees have been submitted from more than 12 school districts across Massachusetts. A panel of judges including scientists, artists, rapid transit representatives, and educators chooses elementary, middle, and high school winners. Winners (6), runners-up (6), and honorable mentions (12) and their families and teachers are invited to an annual Cool Science Award Ceremony to be recognized and view winning artwork. All winning artwork is posted on the Cool Science website. The winning artwork (2 per grade band) is converted into placards (11" x 28") and posters (2.5' x 12') that are placed on the inside (placards) and outside (posters) of buses. Posters are displayed for one month. So far, Cool Science was implemented in Lowell, MA where over 5000 public viewers see the posters daily on the sides of Lowell Rapid Transit Authority (LRTA) buses, making approximately 1,000,000 impressions per year. Cool Science acts to increase climate literacy in children as well as the public, and as such promotes intergenerational learning. Using art in conjunction with science learning about climate change appears to be effective at engaging not just traditionally high achieving science students, but also those interested in the creative arts. Hearing winners' stories about how they created their artwork and what this contest meant to them supports the idea that Cool Science attracts a wide diversity of students. Parents discuss climate change with their children. Multiple press releases announcing the winners further promotes the awareness of climate change throughout school districts and their

  16. Short-term energy forecast evaluation program. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1982-02-15

    This project encompassed a variety of activities intended to provide better tools and understanding of the methods which might be used to evaluate the forecasting of energy supply and disposition. It started with a statistical analysis of the forecast for motor gasoline demand. Following this effort, a broader approach was taken to test forecasting techniques of models which might be cost-effective as alternatives to the ones presently in use. Following the development of a trend extrapolation model, an effort was made to compile a data base of energy series (both historical and forecasts) which could be used to compare actual energy supply and demand to prior forecasts. Once a preliminary data base was established, a set of forecast evaluation statistics was prepared and used to evaluate petroleum forecasts.

    Qualitative and quantitative biodiesel fueling performance and operational data have been collected from urban mass transit buses at Bi-State Development Agency in St. Louis Missouri. A total of 10 vehicles were selected for fueling; 5-6V92 TA Detroit Diesel engines have been fueled with a 20/80 biodiesel/diesel fuel blend and 5-6V92 TA Detroit Diesel control vehicles have been fueled on petroleum based low sulfur diesel fuel (LSD). The real-world impact of a biodiesel blend on maintenance, reliability, cost, fuel economy and safety compared to LSD will be presented. In addition, engine exhaust emissions data collected by the University of West Virginia Department of Energy (DOE) sponsored mobile emissions laboratory will be presented. Operational data from Bi-State Development Agency is collected by the University of Missouri and quality control procedures are performed prior to placing the data in the Alternative Fuels Data Center (AFDC). The AFDC is maintained by the National Renewable Energy Laboratory in Golden, Colorado. This effort, which enables transit operators to review a real-world comparison of biodiesel and LSD, has been funded by the National Biodiesel Board with funds provided by the United Soybean Board with national checkoff dollars and the National Renewable Energy Laboratory.

  18. CNG/diesel buses for Texas school districts

    International Nuclear Information System (INIS)

    At the present time, the preponderance of trucks, buses and other heavy duty vehicles are powered by diesel engines. The reasons for the change from gasoline to diesel engines are all basically economic, due to the longer life and lower operating costs of diesel engines, as compared to gasoline engines. This provides a compelling reason to continue to use these engines, even if powered by fuel other than diesel. A major strategy within the industry has been the various attempts to adapt diesel engines to alternative fuels. These conversions have been largely to either methanol or natural gas, with propane joining the race just recently. This strategy takes advantage of the remaining life of existing vehicles by converting engines rather than purchasing a new engine (and/or vehicle) designed for and dedicated to an alternate fuel. Although diesel engines have been converted to run on natural gas, there are substantial challenges that must be met. The following describes some of the technical approaches being used for diesel engine conversions

    1977-06-01

    Traffic flows through the streets of Southeast Asian countries even though they are used for almost all aspects of human and animal existence. The carts, bicycles, tricycles, and motorcycles, motorized three-wheelers, mini-buses are the so-called intermediate-transport vehicles. It is upon this group of vehicles that a culture--constrained by its own unique economic, environmental, and technological factors--exerts its influence most directly toward the solution of the transport problem. Transportation fills more service roles in Southeast Asian cities than in Western cities. Communication facilities such as telephones and postal services are notoriously unreliable. The personal encounter is all important in social and business interactions in Southeast Asia. Each of the transport modes is examined in view of design and use in a number of specific cultural settings for the countries in Southeast Asia. Present use of intermediate transport in developed countries is discussed briefly, and its further development predicted--pointing out the health and conservation advantages. (MCW)

  20. Multi-criteria analysis of alternative-fuel buses for public transportation

    International Nuclear Information System (INIS)

    The technological development of buses with new alternative fuels is considered in this paper. Several types of fuels are considered as alternative-fuel modes, i.e., electricity, fuel cell (hydrogen), and methanol. Electric vehicles may be considered the alternative-fuel vehicles with the lowest air pollution. Hybrid electric vehicles provide an alternate mode, at least for the period of improving the technology of electric vehicles. A hybrid electric vehicle is defined as a vehicle with the conventional internal combustion engine and an electric motor as its major sources of power. Experts from different decision-making groups performed the multiple attribute evaluation of alternative vehicles. AHP is applied to determine the relative weights of evaluation criteria. TOPSIS and VIKOR are compared and applied to determine the best compromise alternative fuel mode. The result shows that the hybrid electric bus is the most suitable substitute bus for Taiwan urban areas in the short and median term. But, if the cruising distance of the electric bus extends to an acceptable range, the pure electric bus could be the best alternative

  5. NNWSI project information management system concepts evaluation report. Final report

    International Nuclear Information System (INIS)

    This report is intended as a first step in developing detailed information management system specifications for the Nevada Nuclear Waste Storage Investigations (NNWSI) Project. The current state of information management at the NNWSI Project level is investigated and an information management system (IMS) is proposed. The IMS as it relates to aspects of Project and records management is discussed. Information management concepts and prospective IMS system components are investigated. Concepts and system components include: indexing, searching, retrieval, data base management system technology, computers, storage media, computer-assisted retrieval (CAR) of microfilm, electronic imaging-based systems, optical character recognition, and communications. Performance criteria and desirable system attributes applicable to the IMS are discussed. Six conceptual system approaches capable of satisfying the performance criteria are defined. System approaches include: fully centralized microfilm system based on CAR retrieval (Approach 1), partially distributed microfilm system based on CAR retrieval (Approach 2), fully distributed microfilm system based on CAR retrieval (Approach 3), fully centralized optical disk system based on electronic image and full-text retrieval (Approach 4), partially distributed optical system based on electron image and full-text retrieval (Approach 5), and fully distributed optical disk system based on electronic image and full-text retrieval (Approach 6). Technical and cost considerations associated with the six conceptual approaches are evaluated. Technical evaluation results indicate Approach 4 is the best conceptual approach, and cost evaluation results show no significant differences among approaches. On the basis of the evaluation, Approach 4 is recommended

  8. Monitoring and evaluation : Yakima/Klickitat fisheries project, Final report 2000; FINAL

    International Nuclear Information System (INIS)

    The monitoring and evaluation objectives and tasks have been developed through a joint process between the co-managers, Yakama Nation (YN, Lead Agency) and Washington Department of Fish and Wildlife (WDFW). The Science/Technical Advisory Committee (STAC), which consists of core members from the co-managers, employs the services of a work committee of scientists, the Monitoring Implementation Planning Team (MIPT) to develop the Monitoring and Evaluation (M and E) Plan. The process employed by STAC to verify these designated activities and the timing of their implementation involved the utilization of the following principles: (1) YKFP monitoring should evaluate the success (or lack of it) of project supplementation efforts and its impacts, including juvenile post release survival, natural production and reproductive success, ecological interactions, and genetics; (2) YKFP monitoring should be comprehensive: and, (3) YKFP monitoring should be done in such a way that results are of use to salmon production efforts throughout and Columbia basin and the region. Utilizing these principles, STAC and MIPT developed this M and ;E action plan in three phases. The first phase was primarily conceptual. STAC and MIPT defined critical issues and problems and identified associated response variables. The second phase was quantitative, which determined the scale and size of an effective monitoring effort. A critical element of the quantitative phase was an assessment of the precision with which response variables can be measured, the probability of detecting real impacts and the sample sizes required for a given level of statistical precision and power. The third phase is logistical. The feasibility of monitoring measures was evaluated as to practicality and cost. The Policy Group has determined that the M and E activities covered by this agreement are necessary, effective and cost-efficient

  9. The effects of urban driving conditions on the operating characteristics of conventional and hybrid electric city buses

    International Nuclear Information System (INIS)

    Highlights: • Operating characteristics of conventional and hybrid electric buses were examined. • Recovery of braking energy offers an excellent opportunity to improve fuel economy. • Speed and altitude profiles of routes have dramatic impacts on the energy recovery. • Capacity of the auxiliary power source has a dramatic impact on the energy recovery. • Round-trip efficiency of the regenerative braking system was calculated to be 27%. - Abstract: The basic operating characteristics of a conventional bus (CB) and a hybrid electric bus (HEB) were examined under urban driving conditions. To perform this examination, real-time operating data from the buses were collected on the Campus-Return route of the Sakarya Municipality. The main characteristics examined were the traction, braking, engine, engine generator unit (EGU), motor/generator (M/G), and ultracapacitor (Ucap) energies and efficiencies of the buses. The route elevation profile and the frequency of stop-and-go operations of the buses were found to have dramatic impacts on the braking and traction energies of the buses. The declining profile of the Campus-Return route provided an excellent opportunity for energy recovery by the regenerative braking system of the HEB. However, owing to the limits on the capacities and efficiencies of the hybrid drive train components and the Ucap, the bus braking energies were not recovered completely. Braking energies as high as 2.2 kW h per micro-trip were observed, but less than 1 kW h of braking energy per micro-trip was converted to electricity by the M/G; the rest of the braking energy was wasted in frictional braking. The maximum energy recovered and stored in the Ucap per micro-trip was 0.5 kW h, but the amount of energy recovered and stored per micro-trip was typically less than 0.2 kW h for the entire route. The cumulative braking energy recovered and stored in the Ucap for the Campus-Return route was 52% of the available brake energy, which was 13.02 kW h

    1987-10-01

    Field performance monitoring was performed at three buildings which use low temperature (42/sup 0/F to 48/sup 0/F) air distribution in conjunction with ice storage. Temperatures, humidities, and airflows were monitored using a datalogger, and space conditions were measured. The performance of the systems is analyzed and evaluated based on the data collected. It was found that the various operational problems encountered were generally not related to the use of cold air distribution, and that this technology can be successfully used to cool buildings. Recommendations are made for design refinements for future cold air distribution systems, further research in cold air distribution, and continued field evaluation of cold air distribution systems.

  14. Methodology for evaluating energy R&D. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Carter, C.

    1997-04-23

    Recent budgetary shortfalls and hightened concern over balancing the federal budget have placed increasing demand on federal agencies to document the cost effectiveness of the programs they manage. In fact, the 1993 Government Performance and Results Act (GPRA) requires that by 1997 each executive agency prepare a Strategic Plan that includes measurable performance goals. By the year 2000, the first round of Annual Reports will become due which describes actual program performance. Despite the growing emphasis on measuring performance of government programs, the technology policy literature offers little in terms of models that program managers can implement in order to assess the cost effectiveness of the programs they manage. While GPRA will pose a major challenge to all federal government agencies, that challenge is particularly difficult for research-oriented agencies such as the Department of Energy. Its basic research programs provide benefits that are difficult to quantify since their values are uncertain with respect to timing, but are usually reflected in the value assigned to applied programs. The difficulty with quantifying benefits of applied programs relates to the difficulties of obtaining complete information on industries that have used DOE`s supported technologies in their production processes and data on cost-savings relative to conventional technologies. Therefore, DOE is one of several research-oriented agencies that has a special need for methods by which program offices can evaluate the broad array of applied and basic energy research programs they administer. The general findings of this report are that few new methods are applicable for evaluation of R&D programs. It seems that peer review and bibliometrics are methods of choice for evaluating basic research programs while more quantitative approaches such as ROI, cost-benefits, etc. might be followed in evaluating applied programs.

  16. Wind tunnel evaluation of the RAAMP sampler. Final report

    International Nuclear Information System (INIS)

    Wind tunnel tests of the Department of Energy RAAMP (Radioactive Atmospheric Aerosol Monitoring Program) monitor have been conducted at wind speeds of 2 km/hr and 24 km/hr. The RAAMP sampler was developed based on three specific performance objectives: (1) meet EPA PM10 performance criteria, (2) representatively sample and retain particles larger than 10 microm for later isotopic analysis, (3) be capable of continuous, unattended operation for time periods up to 2 months. In this first phase of the evaluation, wind tunnel tests were performed to evaluate the sampler as a potential candidate for EPA PM10 reference or equivalency status. As an integral part of the project, the EPA wind tunnel facility was fully characterized at wind speeds of 2 km/hr and 24 km/hr in conjunction with liquid test aerosols of 10 microm aerodynamic diameter. Results showed that the facility and its operating protocols met or exceeded all 40 CFR Part 53 acceptance criteria regarding PM10 size-selective performance evaluation. Analytical procedures for quantitation of collected mass deposits also met 40 CFR Part 53 criteria. Modifications were made to the tunnel's test section to accommodate the large dimensions of the RAAMP sampler's instrument case

    This article reports on research to explore if pre-registration nursing students felt prepared to manage patients' skin integrity effectively on registration. Final year nursing students completing adult, child and mental health fields were invited to complete questionnaires to investigate the amount of teaching sessions delivered in university in relation to managing skin integrity during their 3-year training programme, discover if pre-registration nursing students received supplementary management of skin integrity teaching in the clinical areas, explore which member of staff in the clinical areas supported the students' learning in the area of skin integrity. Data was collected on 217 final year students (196 females and 21 males) at two higher education institutions in the north of England. The majority of respondents (n = 146; 68%) reported receiving less than 10 hours formal teaching at university on the subject of skin integrity over their 3-year courses. Of those registered on degree courses, 134 students (71%) reported receiving less than 10 hours formal teaching over their 3-year courses, compared with only 12 students (46%) registered on diploma courses. Some 198 (99%) of respondents reported that their clinical teaching was undertaken by registered nurses all or some of the time. Other health professionals were reported to provide substantially less clinical teaching; with the next largest contribution reported to be provided by specialist nurses, who provided all clinical teaching to 36 respondents (19%) and some clinical teaching to 115 respondents (59%). Some 149 respondents (70%) reported that the teaching they received had developed their knowledge and skills to maintain skin integrity for all patients. Respondents claimed that teaching received had developed their knowledge and skills, reporting an average of 16.9 hours spent in directed study; whereas those who did not claim that teaching they had received had developed their knowledge and

  20. Safety evaluation of asphalt products for final disposal

    International Nuclear Information System (INIS)

    Under the present situation, the wastes concentrated according to the radioactivity level, the properties and the environmental conditions are usually solidified in view of limiting the escape of the radioactive substances to the environment as small as possible by containment. The materials used for the solidification are cement, asphalt, plastics, ceramics and so on, and the selection is made by taking the kinds and radioactivity level of wastes, final disposing method, economy and handling into consideration. Asphalt is more suitable than cement to the wastes coming from PWR power plants, which contain boric acid for controlling nuclear reaction, and the effect of reducing the volume of wastes is high. It is economical when a certain scale is reached, accordingly recently, the use of asphalt for the solidification of wastes is going to increase. For the solidification of low level wastes, straight-run asphalt is suitable, and for high level wastes, heat-resistant blown asphalt is suitable. Asphalt-solidified bodies can contain 40-60 wt.% of wastes without any problem. The present situation of asphalt solidification in foreign countries, the physical properties required for the disposal of asphalt-solidified bodies, and the leaching, combustibility, radiation resistance and form stability of asphalt-solidified bodies are described.

    Buelt, J.L. (comp.)

    1983-09-01

    The Liner Evaluation for Uranium Mill Tailings Program was conducted to evaluate the need for and performance of prospective lining materials for the long-term management of inactive uranium mill tailings piles. On the basis of program results, two materials have been identified: natural foundation soil amended with 10% sodium bentonite; catalytic airblown asphalt membrane. The study showed that, for most situations, calcareous soils typical of Western US sites adequately buffer tailings leachates and prevent groundwater contamination without additional liner materials or amendments. Although mathematical modeling of disposal sites is recommended on a site-specific basis, there appears to be no reason to expect significant infiltration through the cover for most Western sites. The major water source through the tailings would be groundwater movement at sites with shallow groundwater tables. Even so column leaching studies showed that contaminant source terms were reduced to near maximum contaminant levels (MCL's) for drinking water within one or two pore volumes; thus, a limited source term for groundwater contamination exists. At sites where significant groundwater movement or infiltration is expected and the tailings leachates are alkaline, however, the sodium bentonite or asphalt membrane may be necessary.

    2007-01-01

    A method used for objective evaluation of pronunciation of finals in standard Chinese is presented. The formant pattern of final is selected as the main feature and an improved evaluation algorithm based on Support Vector Machine is proposed. In this algorithm, two-level classification strategy is employed. A full-classification model and a sub-classification model are trained for each final. The pronunciation quality is evaluated based on the classification results of this two-level strategy with scoring model of each final. The new evaluation method is compared with traditional methods such as Hidden Markov Model (HMM) posterior probability scoring method and feature of Mel-Frequency Cepstrum Coefficients (MFCC), and the results show that the performance is effectively improved by the proposed method. The correlation of scores between human testers and machine has achieved 82%.

    2015-10-19

    This study evaluates the costs and benefits associated with the use of a stationary-wireless- power-transfer-enabled plug-in hybrid electric bus and determines the cost effectiveness relative to a conventional bus and a hybrid electric bus. A sensitivity sweep was performed over many different battery sizes, charging power levels, and number/location of bus stop charging stations. The net present cost was calculated for each vehicle design and provided the basis for design evaluation. In all cases, given the assumed economic conditions, the conventional bus achieved the lowest net present cost while the optimal plug-in hybrid electric bus scenario beat out the hybrid electric comparison scenario. The study also performed parameter sensitivity analysis under favorable and high unfavorable market penetration assumptions. The analysis identifies fuel saving opportunities with plug-in hybrid electric bus scenarios at cumulative net present costs not too dissimilar from those for conventional buses.

    2014-06-01

    Optimization of activities with the aim to provide quality service in conditions of high profitability, is one of the main objectives chased by managers in transportation companies. As a consequence, directing the attention towards monitoring of maintenance activities of vehicles fleet, can achieve desired results. Two of the most important issues related to the maintenance activity, is the increase of reliability and reduction of fuel consumption of the vehicles fleet. Aforementioned actions represents a way forward for raising the quality and profitability of services offered. In this paper, the main ways of monitoring the fuel consumption, in order to reduce it and increase the reliability of transportation vehicles fleet, are presented. For the evaluation of the maintenance system and the degree of influence of malfunctions recorded on the fuel consumption, using the Pareto -ABC method, following case study on a fleet of buses for urban public transport has been conducted. Results obtained highlights the deficiencies of the maintenance process carried out and constitutes a solid base for the reorganization of the maintenance activity, involving preventive maintenance activities, in order to contribute decisively to the results targeted by the management of transport companies.

  7. Electrolytic hydrogen production infrastructure options evaluation. Final subcontract report

    Fuel-cell electric vehicles have the potential to provide the range, acceleration, rapid refueling times, and other creature comforts associated with gasoline-powered vehicles, but with virtually no environmental degradation. To achieve this potential, society will have to develop the necessary infrastructure to supply hydrogen to the fuel-cell vehicles. Hydrogen could be stored directly on the vehicle, or it could be derived from methanol or other hydrocarbon fuels by on-board chemical reformation. This infrastructure analysis assumes high-pressure (5,000 psi) hydrogen on-board storage. This study evaluates one approach to providing hydrogen fuel: the electrolysis of water using off-peak electricity. Other contractors at Princeton University and Oak Ridge National Laboratory are investigating the feasibility of producing hydrogen by steam reforming natural gas, probably the least expensive hydrogen infrastructure alternative for large markets. Electrolytic hydrogen is a possible short-term transition strategy to provide relatively inexpensive hydrogen before there are enough fuel-cell vehicles to justify building large natural gas reforming facilities. In this study, the authors estimate the necessary price of off-peak electricity that would make electrolytic hydrogen costs competitive with gasoline on a per-mile basis, assuming that the electrolyzer systems are manufactured in relatively high volumes compared to current production. They then compare this off-peak electricity price goal with actual current utility residential prices across the US.

    Personal exposure and ambient concentrations of 105 chemical species were determined during September in Stockholm, a northern urban area. This unique study provided personal exposure data equivalent to 8 person-days each on diesel and ethanol buses, and 12 person-days on streets in the urban area. If used judiciously, these data, and the ambient data, are useful for risk assessment, as well as for validation of dispersion models. The concentrations for many species were relatively low, when compared to results from other studies of outdoor concentrations in urban areas. This was probably due to the meteorological conditions during the study which favoured low concentrations. Personal exposures were generally higher than ambient concentrations, probably because of the proximity of subjects to sources of contaminants. As expected, alcohol compounds were found at greater levels in ethanol fueled buses and at bus stops on routes with predominantly ethanol fueled buses. No trends were evident for exposures of VOCs or PAC on diesel and ethanol buses. Exposures to particles at the bus stops were lower than exposures on buses, possibly due to the low traffic volumes at the bus stops, and the proximity of subjects on buses to other traffic. Upon factor analysis of the data, five factors explained the majority of the variance in the results, and showed associations between selected species and a few other parameters. These associations should be useful to design more efficient studies in the future. The chemical element mass balance results with measured profiles yielded uncertain results, but with literature profiles, the diesel and ethanol bus emissions accounted for a small fraction, i.e. < 5%, of the exposures 26 refs, 6 figs, 3 tabs

    Exhaust emissions of 23 individual city buses at Euro III, Euro IV and EEV (Enhanced Environmentally Friendly Vehicle) emission levels were measured by the chasing method under real-world conditions at a depot area and on the normal route of bus line 24 in Helsinki. The buses represented different technologies from the viewpoint of engines, exhaust after-treatment systems (ATS) and fuels. Some of the EEV buses were fueled by diesel, diesel-electric, ethanol (RED95) and compressed natural gas (CNG). At the depot area the emission factors were in the range of 0.3-21 × 10(14) # (kg fuel)(-1), 6-40 g (kg fuel)(-1), 0.004-0.88 g (kg fuel)(-1), 0.004-0.56 g (kg fuel)(-1), 0.01-1.2 g (kg fuel)(-1), for particle number (EFN), nitrogen oxides (EFNOx), black carbon (EFBC), organics (EFOrg), and particle mass (EFPM1), respectively. The highest particulate emissions were observed from the Euro III and Euro IV buses and the lowest from the ethanol and CNG-fueled buses, which emitted BC only during acceleration. The organics emitted from the CNG-fueled buses were clearly less oxidized compared to the other bus types. The bus line experiments showed that lowest emissions were obtained from the ethanol-fueled buses whereas large variation existed between individual buses of the same type indicating that the operating conditions by drivers had large effect on the emissions.

  14. Optimal Memoryless Encoding for Low Power Off-Chip Data Buses

    2007-01-01

    Off-chip buses account for a significant portion of the total system power consumed in embedded systems. Bus encoding schemes have been proposed to minimize power dissipation, but none has been demonstrated to be optimal with respect to any measure. In this paper, we give the first provably optimal and explicit (polynomial-time constructible) families of memoryless codes for minimizing bit transitions in off-chip buses. Our results imply that having access to a clock does not make a memoryless encoding scheme that minimizes bit transitions more powerful.

  17. First final evaluation of the ecological comparison `rape seed-biodiesel versus ordinary diesel oil`

    Energy Technology Data Exchange (ETDEWEB)

    1999-11-01

    Since the beginning of the nineties methodology and content of LCAs on `Rape Seed Biodiesel versus Ordinary Diesel Oil` have continuously been developed. Based on this solid knowledge a final evaluation of the ecological advantages and disadvantages of rape seed biodiesel (RME) as a substitute for diesel oil is now possible. The present final evaluation includes a comparison of the `specific contributions` of selected environmental impact categories followed by a verbal, i.e. non-quantitative final evaluation that draws on their `ecological relevance`. The results show that an overall final assessment in favour of RME can be justified because this fuel obtains better results in two of the three most important environmental impact categories (`resource demand`, `greenhouse effect`). But since there is strong interpretational ambiguity concerning the third category `ozone depletion` this assessment is not inescapable. The results of this evaluation model cannot be completely scientifically objective because they depend on time, place, user and circumstance. Therefore the evaluation process, especially the system boundaries, have to be explicitely documented in order to allow a comprehensible review. (orig.)

  1. Detection of maximum loadability limits and weak buses using Chaotic PSO considering security constraints

    International Nuclear Information System (INIS)

    Highlights: → The unique cost function is derived considering practical Security Constraints. → New innovative formulae of PSO parameters are developed for better performance. → The inclusion and implementation of chaos in PSO technique is original and unique. → Weak buses are identified where FACTS devices can be implemented. → The CPSO technique gives the best performance for all the IEEE standard test systems. - Abstract: In the current research chaotic search is used with the optimization technique for solving non-linear complicated power system problems because Chaos can overcome the local optima problem of optimization technique. Power system problem, more specifically voltage stability, is one of the practical examples of non-linear, complex, convex problems. Smart grid, restructured energy system and socio-economic development fetch various uncertain events in power systems and the level of uncertainty increases to a great extent day by day. In this context, analysis of voltage stability is essential. The efficient method to assess the voltage stability is maximum loadability limit (MLL). MLL problem is formulated as a maximization problem considering practical security constraints (SCs). Detection of weak buses is also important for the analysis of power system stability. Both MLL and weak buses are identified by PSO methods and FACTS devices can be applied to the detected weak buses for the improvement of stability. Three particle swarm optimization (PSO) techniques namely General PSO (GPSO), Adaptive PSO (APSO) and Chaotic PSO (CPSO) are presented for the comparative study with obtaining MLL and weak buses under different SCs. In APSO method, PSO-parameters are made adaptive with the problem and chaos is incorporated in CPSO method to obtain reliable convergence and better performances. All three methods are applied on standard IEEE 14 bus, 30 bus, 57 bus and 118 bus test systems to show their comparative computing effectiveness and

    Full Text Available Purpose. Use efficiency improvement of trolley buses in passenger traffic based on power levels of electric energy input and terms adjustment of their maintenance. Methodology. In order to achieve this goal conformance of electric energy input by trolleybus to the transported amount of passengers taking into account characteristics of the route is offered to establish. The major indicators of the trolleybus operation are: speed of a race on lines, number of tractive motor firing, voltage and amperage in the network that were taken with accountants from a dashboard. Research results were tabulated and recorded with DVR. Along with the study of power consumption of electric energy input by a trolleybus passenger count was carried out too. Findings. The directly proportional dependence between the level of energy consumption by a trolleybus and the number of passengers for constant performance route was determined. Originality. As the criteria for evaluating the effectiveness of the trolleybus operation on the route is proposed to use the ratio between electricity consumption and number of passengers for these characteristics of the route. This is confirmed experimentally. The obtained formulas give the possibility to balance the force work and consequently the volume of energy consumption during the trolleybus movement on the rise and the descent. Practical value. The proposed criterion can be used to adjust the terms of maintenance on the individual program, that means individual maintenance (IM. Type of work performed at the IM should be determined on the basis of diagnostic data of the vehicle (V. The principles of IM were formulated: 1 the primary task is planned and preventative strategy to identify and eliminate troubleshooting and technical actions; 2 operational control of the vehicle (V technical condition on the basis of prediction of its state using the proposed criteria, that takes into account the dependence of power consumption to

  10. Evaluation of the contribution of radiological imaging to the final diagnosis in medical case reports

    International Nuclear Information System (INIS)

    To evaluate the clinical value and impact of radiological imaging in published medial case reports. We analysed 671 consecutively published case reports of a peer-reviewed medical journal for case reports. The general use of radiological imaging as well as the specific imaging modality used in each case (ultrasound, x-ray, fluoroscopy, CT, MRI) was documented, and most importantly the 'final problem solver', i.e. the diagnostic modality giving the final clue to the patient's diagnosis, was identified. In 511 of 671 (76.1 %) analysed case reports at least one radiological modality was used in the diagnostic cascade. In 28.6 % of all cases the final diagnosis was achieved by radiological imaging. All other cases were solved by the patient's history and physical examination (15.2 %), histology (12.4 %), and blood analysis (9.6 %). When radiology was the 'final problem solver', it was mainly CT (51.6 %) and MRI (30.6 %). In 52.2 % of the case reports the radiological image was included in the article. In case reports published in a prominent general medical journal radiological imaging is an important key player in the diagnostic process. In many cases, it is also the diagnostic tool which ultimately leads to determining the final diagnosis. (orig.)

  14. From prototype to product. The development of low emission natural gas- and biogas buses

    Energy Technology Data Exchange (ETDEWEB)

    Ekelund, M. [Strateco Development AB, Haninge (Sweden)

    1998-01-01

    The objective of this report is to show the development of natural gas and bio gas buses and trucks since the termination of the `Co-Nordic GasBus Project`, to which KFB was a major contributor and one of the initiators. Sweden have some 325 heavy duty methane vehicles of which almost 100 are bio gas operated. Scania and Volvo have produced, or have orders for, 500 gas buses to 6 different countries since 1990. The Project objectives were obtained and the significantly reduced emission levels aimed for, were shown. The international bus manufacturing industry followed, and have since shown the same low levels of emissions from gas bus engines. Sweden has taken the lead in the use of bio gas, by operating nearly 100 buses and trucks. Bio gas is still an underestimated fuel when it comes to supply, as it can provide fuel for 50% of the domestic use of diesel oil. Future development need to include control systems for more stable emissions, lower weight cylinders, less costly compressors, cleaning equipment and storage cylinders as well as more fuel efficient engines that can reduce mainly the discharge of CO2, NOx and CH4 further. Societal costs, regardless of who pays, for methane operated buses is still somewhat higher compared with best use of diesel + CRT technology. As commercialization develops, it is expected that the price of the vehicle will be reduced and emissions improved. It is therefore expected that the stake holders costs will be lower then that of diesel technology in the future

    This 4.5-year project consisted of routine analytical support to DOE`s direct liquefaction process development effort (the Base Program), and an extensive effort to develop, demonstate, and apply new analytical methods for the characterization of liquefaction process streams (the Participants Program). The objective of the Base Program was to support the on-going DOE direct coal liquefaction process development program. Feed, process, and product samples were used to assess process operations, product quality, and the effects of process variables, and to direct future testing. The primary objective of the Participants Program was to identify and demonstrate analytical methods for use in support of liquefaction process develpment, and in so doing, provide a bridge between process design, development, and operation and analytical chemistry. To achieve this direct coal liquefaction-derived materials. CONSOL made an evaluation of each analytical technique. During the performance of this project, we obtained analyses on samples from numerous process development and research programs and we evaluated a variety of analytical techniques for their usefulness in supporting liquefaction process development. Because of the diverse nature of this program, we provide here an annotated bibliography of the technical reports, publications, and formal presentations that resulted from this program to serve as a comprehensive summary of contract activities.

  17. Performance of optimised SCR retrofit buses under urban driving and controlled conditions

    2015-03-01

    This work presents the first comprehensive real-world emissions results from urban buses retrofitted with an optimised low-NO2 selective catalytic reduction (SCR) system. The SCRT system combines a CRT (Continuously Regenerating Trap) to reduce particle emissions and SCR to reduce NOx emissions. The optimised low-NO2 SCRT was designed to work under urban conditions where the vehicle exhaust gas temperature is often too low for many SCR systems to work efficiently. The system was extensively tested through on-road and test track measurements using a vehicle emission remote sensing instrument capable of measuring both nitric oxide (NO) and nitrogen dioxide (NO2). Over 700 on-road measurements of the SCRT system were made in London. Compared with identical buses operating under the same conditions fitted with a CRT, NO2 emissions were reduced by 61% and total NOx by 45%. Under test track conditions reductions in NOx of 77% were observed. The test track results do reveal however that compared with an original Euro III bus without a CRT, the SCRT retrofit bus emissions of NO2 are 50% higher. Engine-out and tailpipe measurements of several important engine parameters under test track conditions showed the important effect of SCR inlet temperature on NOx conversion efficiency. Overall, we conclude that retrofitting urban buses to use low-NO2 SCRT systems is an effective method for delivering NOx and NO2 emissions reduction.

    2011-01-01

    Full Text Available This paper studies the difference in computational power between the mesh-connected parallel computers equipped with dynamically reconfigurable bus systems and those with static ones. The mesh with separable buses (MSB is the mesh-connected computer with dynamically reconfigurable row/column buses. The broadcasting buses of the MSB can be dynamically sectioned into smaller bus segments by program control. We examine the impact of reconfigurable capability on the computational power of the MSB model, and investigate how computing power of the MSB decreases when we deprive the MSB of its reconfigurability. We show that any single step of the MSB of size n×n can be simulated in O(log n time by the MSB without its reconfigurable function, which means that the MSB of size n×n can work withO(log n step slowdown even if its dynamic reconfigurable function is disabled.

  19. Clinical observed performance evaluation: a prospective study in final year students of surgery.

    2010-06-24

    We report a prospective study of clinical observed performance evaluation (COPE) for 197 medical students in the pre-qualification year of clinical education. Psychometric quality was the main endpoint. Students were assessed in groups of 5 in 40-min patient encounters, with each student the focus of evaluation for 8 min. Each student had a series of assessments in a 25-week teaching programme. Over time, several clinicians from a pool of 16 surgical consultants and registrars evaluated each student by direct observation. A structured rating form was used for assessment data. Variance component analysis (VCA), internal consistency and inter-rater agreement were used to estimate reliability. The predictive and convergent validity of COPE in relation to summative OSCE, long case, and overall final examination was estimated. Median number of COPE assessments per student was 7. Generalisability of a mean score over 7 COPE assessments was 0.66, equal to that of an 8 x 7.5 min station final OSCE. Internal consistency was 0.88-0.97 and inter-rater agreement 0.82. Significant correlations were observed with OSCE performance (R = 0.55 disattenuated) and long case (R = 0.47 disattenuated). Convergent validity was 0.81 by VCA. Overall final examination performance was linearly related to mean COPE score with standard error 3.7%. COPE permitted efficient serial assessment of a large cohort of final year students in a real world setting. Its psychometric quality compared well with conventional assessments and with other direct observation instruments as reported in the literature. Effect on learning, and translation to clinical care, are directions for future research.

    The authors report final-year ward simulation data from the University of Dundee Medical School. Faculty who designed this assessment intend for the final score to represent an individual senior medical student's level of clinical performance. The results are included in each student's portfolio as one source of evidence of the student's capability as a practitioner, professional, and scholar. Our purpose in conducting this study was to illustrate how assessment designers who are creating assessments to evaluate clinical performance might develop propositions and then collect and examine various sources of evidence to construct and evaluate a validity argument. The data were from all 154 medical students who were in their final year of study at the University of Dundee Medical School in the 2010-2011 academic year. To the best of our knowledge, this is the first report on an analysis of senior medical students' clinical performance while they were taking responsibility for the management of a simulated ward. Using multi-facet Rasch measurement and a generalizability theory approach, we examined various sources of validity evidence that the medical school faculty have gathered for a set of six propositions needed to support their use of scores as measures of students' clinical ability. Based on our analysis of the evidence, we would conclude that, by and large, the propositions appear to be sound, and the evidence seems to support their proposed score interpretation. Given the body of evidence collected thus far, their intended interpretation seems defensible. PMID:25808311

  3. Evaluating public involvement in the national low-level radioactive-waste-management program. Final report

    International Nuclear Information System (INIS)

    An extensive public involvement approach has been developed to obtain the views and assistance of state and local governments, citizen groups, industry, professional societies and other organizations in the preparation and review of a national strategy document on low-level radioactive wastes. Six evaluators who have a wide diversity of backgrounds were selected to evaluate the effectiveness of this approach. This final report presents findings discussed under the headings: Introduction to the Recent History of Low-level Waste Policy Development (LLWMP) and the Role of Public Participation; Public Participation Mechanisms Employed in Preparing the National Strategy Document; the Keystone's Evaluation Process; and Findings. The overall evaluation of the process was very positive. It was clear that the LLWMP staff was seriously committed to building a credible public participation process. The evaluation team was provided rough cost figures for the various components of the LLWMP effort and concluded that, in its opinion, the public participation process provided benefits to the federal government that exceeded its costs. Moreover, the costs of the individual components were not out of line with each one's usefulness and contribution to the overall effort

  6. Analysis of the cost of hydrogen infrastructure for buses in London

    Science.gov (United States)

    Shayegan, S.; Hart, D.; Pearson, P.; Joffe, D.

    The use of hydrogen (H 2) as transport fuel is often said to suffer from the 'chicken and egg' problem: vehicles that depend on H 2 cannot go on the roads due to the lack of an adequate infrastructure, and the almost non-existent fleet of H 2 vehicles on the roads makes it economically unsound to build a H 2 infrastructure. Although both hydrogen vehicles (fuel cell and internal combustion engine) and the related infrastructure have been (and are being) developed and some are commercially available, cost is seen as a major barrier. With today's technologies, H 2 only becomes competitive with petrol and diesel when produced at large quantities, suitable for supplying e.g. thousands of H 2 buses. The question is, how might this point be reached, and are there least cost infrastructural pathways to reach it. This paper tries to address the latter question, using the early development of a H 2 infrastructure for buses in London as a case study. The paper presents some of the analyses and results from a Ph.D. project (in progress) being undertaken at Imperial College London, funded by EPSRC (Grant GR/R50790/01). The results presented here illustrate that cost of hydrogen production and delivery vary mainly with levels of hydrogen demand and delivery distances, as well as other logistic criteria; least cost production-delivery pathways have been identified for various hydrogen demand scenarios and refuelling station set-ups. Another important conclusion is that the pattern of converting a group of refuelling stations to hydrogen (e.g. a group of refuelling stations for buses in London) has a significant effect on the unit cost of hydrogen.

    The device information is collected using standardized Filed Buses with high data transmission capacity, which allows the analysis of his operational status in real time. The quantity of information generated by the devices for the maintenance area is increasing and this data quantity transferred through the field bus should not interfere in the network performance to the point of degrade his control function. In this way, is presented a technique that can be used in different protocols, which allow sending of maintenance data using a small band of the communication channel. Operational integrity can be achieved using predictive maintenance techniques based on the collected data. (author)

    For almost two years now, the Global Precipitation Measurement (GPM) mission has provided worldwide satellite rainfall estimates at higher spatiotemporal resolutions than its predecessor TRMM (Tropical Rainfall Measurement Mission). Accurate rainfall estimates at higher resolutions are the main input in modeling physical processes relevant to society like floods, landslides, and weather extremes. Conversely to TRMM Multi-satellite Precipitation Analysis (TMPA) products, the Netherlands is within the coverage of GPM Level-3 products, i.e., IMERG (Integrated Multi-satellite Retrievals for GPM). The IMERG spatiotemporal resolution is 0.1° x 0.1° every 30 min (180°W to 180°E, and 60&Deg;N to 60°S), with latencies of 6, 18 hours and 4 months. Here we evaluate the first full year of the IMERG Day 1 Final Run over the land surface of the Netherlands. IMERG Final Run is considered the research product, and provides the longest public data set among IMERG products. We compare half-hourly and daily IMERG rainfall maps against Dutch gauge-adjusted radar rainfall maps. Radar rainfall maps are provided by the Royal Netherlands Meteorological Institute (KNMI), and are considered as the ground truth given its accuracy, spatiotemporal resolution and availability. In general, there is a tendency of GPM to underestimate rainfall intensities over the land surface of the Netherlands. Nevertheless, this underestimation is relatively low, which suggests a potential applicability of IMERG Final Run as a reliable source of rainfall estimates in diverse hydrological and hydrometeorological applications. The robustness and data availability of IMERG is an important asset, especially in places where rain gauge networks are scarce or poorly maintained, or where weather radar networks are too expensive to acquire and/or maintain.

    2011-10-01

    In India the emissions rate and fuel consumption of intra-city buses are estimated using the European driving cycles, which don't represent Indian driving conditions and in-use operation of vehicles. This leads to underestimation or overestimation of emissions and fuel consumption. In this context, this paper offers some insight into the driving characteristics of intra-city buses using a Global Positioning System. The study has revealed that irrespective of road type and time of travel, a higher percentage of time is spent in idle mode. This is primarily due to alighting and boarding of passengers at regular intervals and fixed delays caused by traffic lights. More than 90 percent of trips have an average speed of less than 30 km h -1. This study has also developed an intra-city bus driving cycle for Chennai and compared it with some well-known international driving cycles. It has revealed that Chennai has unique driving characteristics and, therefore, it may not be appropriate to adopt a driving cycle of another country or city.

    This paper evaluates strategies for operating buses on signal-controlled arterials using special lanes that are made intermittently available to general traffic. The advantage of special bus lanes, intermittent or dedicated, is that they free buses from traffic interference; the disadvantage is that they disrupt traffic. We find that intermittent lanes, unlike dedicated ones, do not significantly reduce street capacity. Intermittence, however, increases the average traffic density at which th...

    Heavy-duty vehicles in Europe and North America will require incylinder measures or exhaust gas after-treatment technology to control emissions and meet ever stringent emission requirements. Alternatively, manufacturers can choose clean burning alternative fuels such as natural gas. Although there are no international standards for heavy-duty vehicle chassis dynamometer testing at present, the IEA Implementing Agreements offer excellent platforms for international collaborative research. Harmonization of test methods for vehicles and fuels is one important task. This paper reported on the work of 3 laboratories that have produced emission results for complete heavy-duty vehicles. VTT Technical Research of Finland, Environment Canada and West Virginia University measured standard size urban buses driving various duty cycles on chassis dynamometers. The number of transient test cycles per laboratory varied from 6 to 16. European and North American diesel and natural gas vehicles were included in the vehicle matrix. The objective was to demonstrate how the driving cycle affects the emission performance of conventional and advanced urban buses. Several driving cycles were run on urban buses to better understand the characteristics of different duty cycles; produce a key for cross-interpretation of emission results generated with different cycles; and study the interaction between vehicle, exhaust after-treatment and fuel technologies and test procedures. Fuel consumption and exhaust emissions were measured. The results varied significantly not only by test cycle, but also by vehicle technology. In general, vehicles emissions were directly proportioned to the amount of fuel consumed, with the exception of NOx-emissions from SCR-vehicles. There was a clear difference in the emission profiles of European and North American vehicles. In Europe, fuel efficiency was emphasized, while in North America, more focus was given to regulated exhaust emissions, especially low

    This paper presents results from the international AcceptH2 study (http://www.accepth2.com) of acceptability and preferences for hydrogen fuel cell (FC) buses. Using the contingent valuation method, this paper compares public willingness to pay (WTP) for the air pollution reductions associated with a scenario of large-scale introduction of hydrogen (H{sub 2}) FC buses in four cities: Berlin, London, Luxembourg and Perth. Results indicate that bus users in all cities have a positive WTP for H{sub 2} buses, and that values (adjusted to the cost of living in each city) are very similar across geographical locations (ranging from WTP an extra Euro 0.29 to Euro 0.35 per single bus fare). Non-bus users were also interviewed in London and Perth, in order to capture values for the whole populations in these cities. Combined results for bus users and non-bus users confirm that overall residents in these cities are willing to pay extra (in taxes) to support the large-scale introduction of H{sub 2}-buses.

  2. Physical characterization of fine particulate matter inside the public transit buses fueled by biodiesel in Toledo, Ohio

    International Nuclear Information System (INIS)

    This study presents the physical characteristics of fine particulate matter (PM) collected inside the urban-public transit buses in Toledo, OH. These buses run on 20% biodiesel blended with ultra-low sulfur diesel (ULSD) (B20). For risk analysis, it is crucial to know the modality of the size distribution and the shape factor of PM collected inside the bus. The number-size distribution, microstructure, and aspect ratio of fine PM filter samples collected in the urban-public transit buses were measured for three years (2007-2009), using an environmental scanning electron microscope (ESEM) coupled with energy dispersive X-ray spectrometry (EDX). Only the reproducible results from repeated experiments on ESEM and size distribution obtained by the GRIMM dust monitor were used in this study. The size distribution was found bi-modal in the winter and fall months and was primarily uni-modal during spring and summer. The aspect ratio for different filter samples collected inside the bus range from 2.4 to 3.6 in average value, with standard deviation ranging from 0.9 to 7.4. The square-shaped and oblong-shaped particles represent the single inhalable particle's morphology characteristics in the air of the Toledo transit buses.

  3. Evaluation of Aeroelastically Tailored Small Wind Turbine Blades Final Project Report

    2005-09-29

    Evaluation of Aeroelastically Tailored Small Wind Turbine Blades Final Report Global Energy Concepts, LLC (GEC) has performed a conceptual design study concerning aeroelastic tailoring of small wind turbine blades. The primary objectives were to evaluate ways that blade/rotor geometry could be used to enable cost-of-energy reductions by enhancing energy capture while constraining or mitigating blade costs, system loads, and related component costs. This work builds on insights developed in ongoing adaptive-blade programs but with a focus on application to small turbine systems with isotropic blade material properties and with combined blade sweep and pre-bending/pre-curving to achieve the desired twist coupling. Specific goals of this project are to: (A) Evaluate and quantify the extent to which rotor geometry can be used to realize load-mitigating small wind turbine rotors. Primary aspects of the load mitigation are: (1) Improved overspeed safety affected by blades twisting toward stall in response to speed increases. (2) Reduced fatigue loading affected by blade twisting toward feather in response to turbulent gusts. (B) Illustrate trade-offs and design sensitivities for this concept. (C) Provide the technical basis for small wind turbine manufacturers to evaluate this concept and commercialize if the technology appears favorable. The SolidWorks code was used to rapidly develop solid models of blade with varying shapes and material properties. Finite element analyses (FEA) were performed using the COSMOS code modeling with tip-loads and centripetal accelerations. This tool set was used to investigate the potential for aeroelastic tailoring with combined planform sweep and pre-curve. An extensive matrix of design variables was investigated, including aerodynamic design, magnitude and shape of planform sweep, magnitude and shape of blade pre-curve, material stiffness, and rotor diameter. The FEA simulations resulted in substantial insights into the structural

    By combining the top performing commercial laser beam stabilization system with the most ideal optical imaging configuration, the beamline for the Linear Accelerator Coherent Light Source II (LCLS-II) will deliver the highest quality and most stable beam to the cathode. To determine the optimal combination, LCLS-II beamline conditions were replicated and the systems tested with a He-Ne laser. The Guidestar-II and MRC active laser beam stabilization systems were evaluated for their ideal positioning and stability. Both a two and four lens optical imaging configuration was then evaluated for beam imaging quality, magnification properties, and natural stability. In their best performances when tested over fifteen hours, Guidestar-II kept the beam stable over approximately 70-110um while the MRC system kept it stable over approximately 90-100um. During short periods of time, Guidestar-II kept the beam stable between 10-20um, but was more susceptible to drift over time, while the MRC system maintained the beam between 30-50um with less overall drift. The best optical imaging configuration proved to be a four lens system that images to the iris located in the cathode room and from there, imaged to the cathode. The magnification from the iris to the cathode was 2:1, within an acceptable tolerance to the expected 2.1:1 magnification. The two lens configuration was slightly more stable in small periods of time (less than 10 minutes) without the assistance of a stability system, approximately 55um compared to approximately 70um, but the four lens configurations beam image had a significantly flatter intensity distribution compared to the two lens configuration which had a Gaussian distribution. A final test still needs to be run with both stability systems running at the same time through the four lens system. With this data, the optimal laser beam stabilization system can be determined for the beamline of LCLS-II.

    The purpose of this Study is to provide an economic review of current and proposed changes to the Select Area Fishery Evaluation Project (SAFE or Project). The Study results are the information requested in comments made on the Project by a joint review dated March 2005 by the Northwest Power and Conservation Council (NPCC) Independent Scientific Review Panel (ISRP) and Independent Economic Analysis Board (IEAB). North et al. (2006) addressed technical questions about operations and plans, and this report contains the response information for comments concerning Project economics. This report can be considered an economic feasibility review meeting guidelines for cost-effective analysis developed by the IEAB (2003). It also contains other economic measurement descriptions to illustrate the economic effects of SAFE. The SAFE is an expansion of a hatchery project (locally called the Clatsop Economic Development Council Fisheries Project or CEDC) started in 1977 that released an early run coho (COH) stock into the Youngs River. The Youngs River entrance to the Columbia River at River Mile 12 is called Youngs Bay, which is located near Astoria, Oregon. The purpose of the hatchery project was to provide increased fishing opportunities for the in-river commercial fishing gillnet fleet. Instead of just releasing fish at the hatchery, a small scale net pen acclimation project in Youngs Bay was tried in 1987. Hirose et al. (1998) found that 1991-1992 COH broodstock over-wintered at the net pens had double the smolt-to-adult return rate (SAR) of traditional hatchery release, less than one percent stray rates, and 99 percent fishery harvests. It was surmised that smolts from other Columbia River hatcheries could be hauled to the net pens for acclimation and release to take advantage of the SAR's and fishing rates. Proposals were tendered to Bonneville Power Administration (BPA) and other agencies to fund the expansion for using other hatcheries smolts and other off

    High-deck buses that have a higher center of gravity traveling at an excessive speed have a higher likelihood of causing serious and fatal accidents when drivers lose control of the vehicle. In addition, drivers who suffer from fatigue in long-distance driving increase the likelihood of serious accident. This paper examines the effects of risk factors contributing to severe crashes associated with high-deck buses used for long-distance driving on freeways. An ordered logit and latent class models are used to examine significant factors on the severity of injuries in crashes related to high-deck buses. Driver fatigue, drivers or passengers not wearing a seat belt, reckless driving, drunk driving, crashes occurred between midnight and dawn, and crashes occurred at interchange ramps were found to significantly affect the severity of injuries in crashes involving high-deck buses. Safety policies to prevent severe injuries in crashes involving high deck buses used for long-distance runs on freeways include: (1) restricting drivers from exceeding the limit of daily driving hours and mandating sufficient rest breaks; (2) installing an automatic sleep-warning device in the vehicle; (3) drivers with obstructive sleep apnea syndrome or sleep disorders should be tested and treated before they are allowed to perform long hours of driving tasks; (4) educating the public or even amending the seatbelt legislation to require all passengers to wear a seat belt and thus reduce the chance of ejection from a high-deck bus and prevent serious injuries in a crash while traveling at a higher speed on freeways.

    This final report describes work performed on a variety of topics related to the materials interactions that would occur following a postulated core-meltdown accident in a Light Water Reactor. The main topics addressed include: (1) an evaluation of candidate core-retention-system materials for the Zion and Indian Point (Z/IP) nuclear reactors; (2) an examination of various core-retention-system concepts with emphasis on the restrictions imposed by the conditions present in the Z/IP reactors; (3) development of a concept for retrofitting the Z/IP reactors with a molten-core retention device; (4) reactor-cavity conditions following vessel failure, including the existence of a hydraulic jump and molten-core entrainment and sweepout; (5) core debris-concrete crust development, and including the effects of composition, strength, gas pressure and surface tension; (6) a discussion of reactor-containment-system materials in the context of interactions with core debris; (7) reactions forming combustible hydrogen, carbon monoxide, and hydrocarbons; (8) a discussion of the properties and behavior of urania and the prospects for decontamination of aerosols in a BWR suppression pool; and (9) the effect of water salinity and acidity on concrete

  9. Demonstration, testing, ampersand evaluation of in situ heating of soil. Draft final report, Volume I

    International Nuclear Information System (INIS)

    This document is a draft final report (Volume 1) for US DOE contract entitled, open-quotes Demonstration Testing and Evaluation of In Situ Soil Heating,close quotes Contract No. DE-AC05-93OR22160, IITRI Project No. C06787. This report is presented in two volumes. Volume I contains the technical report and Volume II contains appendices with background information and data. In this project approximately 300 cu. yd. of clayey soil containing a low concentration plume of volatile organic chemicals was heated in situ by the application of electrical energy. It was shown that as a result of heating the effective permeability of soil to air flow was increased such that in situ soil vapor extraction could be performed. The initial permeability of soil was so low that the soil gas flow rate was immeasurably small even at high vacuum levels. When scaled up, this process can be used for the environmental clean up and restoration of DOE sites contaminated with VOCs and other organic chemicals boiling up to 120 degrees to 130 degrees C in the vadose zone. Although it may applied to many types of soil formations, it is particularly attractive for low permeability clayey soil where conventional in situ venting techniques are limited by low air flow

    We present simulated fuel economy and emissions city transit buses powered by conventional diesel engines and diesel-hybrid electric powertrains of varying size. Six representative city drive cycles were included in the study. In addition, we included previously published aftertreatment device models for control of CO, HC, NOx, and particulate matter (PM) emissions. Our results reveal that bus hybridization can significantly enhance fuel economy by reducing engine idling time, reducing demands for accessory loads, exploiting regenerative braking, and shifting engine operation to speeds and loads with higher fuel efficiency. Increased hybridization also tends to monotonically reduce engine-out emissions, but trends in the tailpipe (post-aftertreatment) emissions involve more complex interactions that significantly depend on motor size and drive cycle details.

  11. Performance study about biodiesel impact on buses engines using dynamometer tests and fleet consumption data

    International Nuclear Information System (INIS)

    Highlights: ► Driving cycle affects the fuel impacts on engine emissions and performance. ► Incorporation of biodiesel can improve efficiency for some engine regimes. ► Biodiesel oxygen content probably increases combustion efficiency in engine. ► The consumption of the fleet agrees with the dynamometer results. ► NOx emissions are very sensitive to engine operating conditions. - Abstract: The problem of reducing harmful emissions, mainly particulate matter (PM) and nitrogen oxides (NOxs) originated in compression ignition combustion engines, and also the mandatory intention of lowering the CO2 impacts of road transportation define the need to improve our knowledge on biodiesel use in engines. A 6 in line cylinders Volvo engine was submitted to a 100 min cycle with 27 stabilized steps for seven different fuel blends from pure fossil diesel (B0) to pure biodiesel (B100), considering also B10, B15, B20, B30, B50 fuel blends. The cycle imposed tries to simulate a normal use of a bus in an urban and extra-urban circuit, considering different engine rotation and loads applied. An analysis on consumption data obtained of a fleet was made. The fleet had near 200 buses, used different fuel blends, and operated in the north of Portugal. Results reveal that the cycle imposed reflects very well the tendency of consumption, allowing to confirm the methodology and also to check influences on consumption, mainly associated with possibilities to decrease CO2 emissions by using some biodiesel blends on buses. This allows increasing the quality of data in vehicle real use and tightening the uncertainties on the actual effects of using biodiesel.

  12. First final evaluation of the ecological comparison 'rape seed-biodiesel versus ordinary diesel oil'

    1999-01-01

    Since the beginning of the nineties methodology and content of LCAs on 'Rape Seed Biodiesel versus Ordinary Diesel Oil' have continuously been developed. Based on this solid knowledge a final evaluation of the ecological advantages and disadvantages of rape seed biodiesel (RME) as a substitute for diesel oil is now possible. The present final evaluation includes a comparison of the 'specific contributions' of selected environmental impact categories followed by a verbal, i.e. non-quantitative final evaluation that draws on their 'ecological relevance'. The results show that an overall final assessment in favour of RME can be justified because this fuel obtains better results in two of the three most important environmental impact categories ('resource demand', 'greenhouse effect'). But since there is strong interpretational ambiguity concerning the third category 'ozone depletion' this assessment is not inescapable. The results of this evaluation model cannot be completely scientifically objective because they depend on time, place, user and circumstance. Therefore the evaluation process, especially the system boundaries, have to be explicitely documented in order to allow a comprehensible review. (orig.)

  15. Final report of the project performance assessment and economic evaluation of nuclear waste management

    International Nuclear Information System (INIS)

    The publication is the final report of project Performance Assessment and Economic Evaluation of Nuclear Waste Management (TOKA) at the Nuclear Engineering Laboratory of VTT (Technical Research Centre of Finland), forming part of the Publicly Financed Nuclear Waste Management Research Programme (JYT). The project covers safety and cost aspects of all phases of nuclear waste management. The main emphasis has been on developing an integrated system of models for performance assessment of nuclear waste repositories. During the four years the project has so far been in progress, the total amount of work has been around 14 person-years. Computer codes are the main tools in the project, they are either developed by the project team or acquired from abroad. In-house model development has been especially active in groundwater flow, near-field and migration modelling. The quantitative interpretation of Finnish tracer experiments in the laboratory and natural analogue studies at Palmottu support performance assessments via increased confidence in the migration concepts used. The performance assessment philosophy adopted by the team consists of deterministic modelling and pragmatic scenario analysis. This is supported by the long-term experience in practical performance assessment of the team, and in theoretical probabilistic modelling exercises. The radiological risks of spent fuel transportation from the Loviisa nuclear power plant to Russia have been analysed using a probabilistic computer code and Finnish traffic accident statistics. The project assists the authorities in the annual assessment of utility estimates of funding needs for future nuclear waste management operations. The models and methods used within the project are tested in international verification/validation projects

  16. Evaluation of final waste forms and recommendations for baseline alternatives to group and glass

    Bleier, A.

    1997-09-01

    An assessment of final waste forms was made as part of the Federal Facilities Compliance Agreement/Development, Demonstration, Testing, and Evaluation (FFCA/DDT&E) Program because supplemental waste-form technologies are needed for the hazardous, radioactive, and mixed wastes of concern to the Department of Energy and the problematic wastes on the Oak Ridge Reservation. The principal objective was to identify a primary waste-form candidate as an alternative to grout (cement) and glass. The effort principally comprised a literature search, the goal of which was to establish a knowledge base regarding four areas: (1) the waste-form technologies based on grout and glass, (2) candidate alternatives, (3) the wastes that need to be immobilized, and (4) the technical and regulatory constraints on the waste-from technologies. This report serves, in part, to meet this goal. Six families of materials emerged as relevant; inorganic, organic, vitrified, devitrified, ceramic, and metallic matrices. Multiple members of each family were assessed, emphasizing the materials-oriented factors and accounting for the fact that the two most prevalent types of wastes for the FFCA/DDT&E Program are aqueous liquids and inorganic sludges and solids. Presently, no individual matrix is sufficiently developed to permit its immediate implementation as a baseline alternative. Three thermoplastic materials, sulfur-polymer cement (inorganic), bitumen (organic), and polyethylene (organic), are the most technologically developed candidates. Each warrants further study, emphasizing the engineering and economic factors, but each also has limitations that regulate it to a status of short-term alternative. The crystallinity and flexible processing of sulfur provide sulfur-polymer cement with the highest potential for short-term success via encapsulation. Long-term immobilization demands chemical stabilization, which the thermoplastic matrices do not offer. Among the properties of the remaining

  19. Implementation of the MARSSIM to Evaluate the Final Status After Decommissioning Uranium Conversion Plant

    International Nuclear Information System (INIS)

    The decommissioning project of Uranium Conversion Plant was launched in 2001 and completed at the first half of 2011. The final stage of decommissioning process was the release of a site and building from regulatory control. KAERI carried out a final status survey based on the guidance provided in the MARSSIM (Multi-Agency Radiation Survey and Site Investigation Manual). The Uranium Conversion Plant was used to manufacture UO2 powder for CANDU fuel, the plant was contaminated only natural uranium. In this study, plans for the final status survey and release criteria for a site were established by applying the MARSSIM procedures. The survey design for the final status survey of the UCP site and buildings was carried out based on the statistical test of the results form scoping and characterization survey. The site and buildings were classified based on the potential contamination by using measured and calculated results. The results of the final status survey were satisfied the release criteria based on the measured data from a site and building. The summarized final status survey results are given in Figure 1 shows detail residual contamination level in Class 1. The results of the final status survey are sufficiently lower than the release criteria. The MARSSIM procedures were proved to be flexible, scientifically rigorous and cost effective for final status survey of decommissioning site and building. For the effective plan for the final status survey of the UCP site and its implementation, KAERI and its the regulation body are continuously discussing way to ensure the validation of the final status survey.

  1. Reliable evaluation of acceptability of weld for final disposal based on the canister copper weld inspection using different NDT methods

    International Nuclear Information System (INIS)

    The inspection of the sealing weld is an important phase for the evaluation of the acceptability of final disposal canister, but the weld is only a part of the 3D shielding of copper shell. The main tasks for reliable NDT evaluation requires an extensive evaluation of the parameters - which contains typical inspection related items like repeatability, S/N ratio, POD, setting up the equipment for inspection, and all practices for inspections. The other parameters are material parameters, their variation must be taken into account in the evaluation of NDT reliability. Further parameters include human factors, i. e. human inspectors and their interaction with technical systems; their effects were studied on an example of the evaluation of eddy current data. Final parameters are related to evaluation of detected defects, which means sizing and base for acceptance and this can be done in different ways. Some examples are given and results are compared with different methods for instance between radiographic testing and ultrasonic testing by raw data analysis and PA-SAFT results. Also, preliminary curves for the evaluation of metallographic results of 55 defects will be shown by EB weld measurements. Some practical items concerning copper inspections will be also discussed related to acceptability.

  2. Enhancement of nondestructive evaluation techniques for magnetic and nonmagnetic structural components (Final report for doctoral fellowship)

    International Nuclear Information System (INIS)

    In this report, research works performed in the Structural Safety Engineering Group of OEC/JNC are summarized as the final report of the doctoral fellowship. The main objective of this study is for the enhancement of the nondestructive evaluation techniques for structural components of both magnetic and nonmagnetic material. Studies in three topics have been carried out aiming at the quantitative evaluation of crack with the eddy current testing and the validation of a natural magnetic field based NDE method for detecting mechanical damages in a paramagnetic material. In the first part of the study, an approach to the reconstruction of the natural crack was proposed and implemented with an idealized crack model for its validation. In the second part, the correlation of the natural magnetization and the mechanical damages in the SUS304 stainless steel was investigated by using an experimental approach. In part 3, an inverse method of the measured magnetic fields is proposed for the reconstruction of magnetic charges in the inspected material by using an optimization method and wavelet. As the first work, an approach to the reconstruction of an idealized natural crack of non-vanishing conductivity is proposed with use of signals of eddy current testing. Two numerical models are introduced at first for modeling the natural crack in order to represented it with a set of crack parameters. A method for the rapid prediction of the eddy current testing signals coming from these idealized cracks is given then by extending a knowledge based fast forward solver to the case of a non-vanishing conductivity. Based on this fast forward solver, the inverse algorithm of conjugate gradient method is updated to identify the crack parameters. Several examples are presented finally as a validation of the proposed strategy. The results show that both the two numerical models can give reasonable reconstruction results for signal of low noise. The model concerning the touch of crack

    2008-11-01

    Emissions during a trip often depend on transient vehicle dynamics that influence the instantaneous engine load. Vehicle specific power (VSP) is a proxy variable for engine load that has been shown to be highly correlated with emissions. This study estimates roadway link average emission rates for diesel-fueled transit buses based on link mean speeds, using newly defined VSP modes from data gathered by a portable emissions monitoring system. Speed profiles were categorized by facility type and mean travel speed, and stratified into discrete VSP modes. VSP modal average emission rates and the time spent in the corresponding VSP modes were then used to make aggregate estimates of total and average emission rates for a road link. The average emission rates were sensitive to link mean speed, but not to facility type. A recommendation is made regarding the implementation of link average emission rates in conjunction with transportation models for the purpose of estimating regional emissions for diesel transit buses.

    Full Text Available En este trabajo se usa un método iterativo para calcular tarifas Pigouvianascuando las vías son compartidas por autos y buses. Se comparan escenarios en los cuales: 1 la tarifa es calculada considerando sólo la externalidad sobre otros vehículos; 2 la tarifa considera además la externalidad sobre los pasajeros de los vehículos; 3 no se aplican tarifas; y 4 no se aplican tarifas, pero algunas pistas son reservadas para el uso exclusivo de buses. El método es aplicado primero a un modelo idealizado que considera homogenidad de la demanda y cierto grado de heterogenidad en la oferta. Luego el método es aplicado en un experimento con datos reales basado en un modelo simultáneo de cuatro etapas calibrado para la ciudad de Santiago, Chile. Todos los experimentos muestran que cuando se considera la externalidad sobre los pasajeros de los vehículos, las tarifas Pigouvianas crecen sustancialmente en las vías de uso mixto, lo cual se traduce en un menor flujo de automóviles en dichas vías. Por otro lado, las simulaciones con el modelo idealizado muestran que el efecto de la reservación de pistas depende fuertemente del diseño considerado. Respecto de la tarificación Pigouviana, el experimento con datos reales muestra, sorprendentemente, que dicha política resultaría ser inferior a un escenario en el cual no se aplican tarifas. Este resultado podría atribuirse a: 1 que el modelo con datos reales representa una situación de equilibrio general y en cambio las tarifas Pigouvianas se calculan usando un enfoque de equilibrio parcial; 2 limitaciones de modelación en el experimento con datos reales; o 3 una manifestación del contraejemplo de Coase para los impuestos Pigouvianos. El artículo termina discutiendo el impacto de estos resultados en el análisis de políticas de transporte urbano.

  2. Fuel consumption reduction in urban buses by using power split transmissions

    International Nuclear Information System (INIS)

    Highlights: • Fuel consumption is highly influenced by transmission layout and control. • Continuous Variable Transmission allows control of the working point of the engine. • Hydromechanical CVT was numerically tested and compared with usual mechanical solutions. • CVT solution proved to reduce fuel consumption, improving the I.C.E. mean efficiency. • Results obtained from standard emission test cycles: New York and Manhattan Buses. - Abstract: The reduction of fuel consumption of urban vehicles is one of the challenges of the society today. Many promising technologies such as hybrid electric vehicles and fuel cells are the focus of a lot of research and investments, but high costs prevent their development on a large scale, especially in heavy duty vehicles. Simpler solutions, such as continuously variable transmissions, are then interesting alternatives: they preserve some of the advantages of hybrid solutions significantly reducing the overall cost of the system. Since these technologies allow the decoupling of the engine’s velocity from that of the wheels, optimised management of the engine becomes feasible, leading to lower fuel consumption than that of traditional solutions. This work compares the hydromechanical transmission with a traditional power shift in an application where efficiency and comfort are required: a city bus. The performance of a vehicle with a dual stage hydromechanical transmission has been investigated by means of a model implemented in the AMESim environment. A second model of a vehicle with a power shift transmission has been taken as reference solution. During the simulation of two standard test cycles, the first vehicle showed the lower fuel consumption, due to its better engine management, and to the operation of the torque converter during starts, which lowers the efficiency of the reference vehicle

  3. Evaluation of new pH control agents for PWR secondary water systems. Final report

    International Nuclear Information System (INIS)

    This report presents an account of work evaluating new organic pH control agents for PWR station secondary systems. A discussion of corrosion control with pH controlling amines is given together with some information on current utility practice with volatile amines. The report describes opportunities for improved corrosion control with new pH controlling amines and the selection of candidates for laboratory evaluation. Progress on EPRI program RP 1571-7, ''Spectroscopic Characterization Methods for New pH Control Agents'', is presented. Also presented is an outline of the second phase of the RP 1571-7 program which was directed toward ''Evaluation of pH Control Agents in Simulated Steam Generator Tubesheet Crevice Environments.'' Quinuclidine and diaminopropane were evaluated using laser Raman spectroscopy. Hydrothermal stability and pH properties at temperature were determined. Quinuclidine was superior to diaminopropane and presents advantages over ammonia, hydrazine and morpholine for plant use as a pH control agent. It was further evaluated in tests with a scaled PWR crevice simulator for corrosion compatibility as well as pH control. 17 refs., 22 figs., 9 tabs

  4. Evaluation of the PISC-2 trials results PISC 2 report No.5. Final issue

    International Nuclear Information System (INIS)

    Ultrasonic testing is widely used for detecting, locating and sizing flaws in primary circuit elements at various stages of plant life. The successive PISC projects have constituted the most notable, sustained, international effort to assess the effectiveness of these inspection techniques. The Programme for the Inspection of Steel Components (PISC-II, 1981-1986) constitutes a detailed evaluation of the best performance obtainable by modern ultrasonic techniques under optimal conditions. The present report gives a complete evaluation of the results of PISC-II obtained on various plates presenting different types of defects. Three levels of evaluation are considered: a comparison between teams, a comparison between procedures, and a comparison of the individual techniques and components of the procedures. Results are discussed as a function of the tolerance on sizing, as a function of subgroups of defects (defect position, size, characteristics)

  6. Intergrated plant safety assessment. Systematic evaluation program. Palisades plant, Consumers Power Company, Docket No. 50-255. Final report

    International Nuclear Information System (INIS)

    The Nuclear Regulatory Commission (NRC) has published its Final Integrated Plant Safety Assessment Report (IPSAR) (NUREG-0820), under the scope of the Systematic Evaluation Program (SEP), for Consumers Power Company's Palisades Plant located in Covert, Van Buren County, Michigan. The SEP was initiated by the NRC to review the design of older operating nuclear reactor plants to reconfirm and document their safety. This report documents the review completed under the SEP for the Palisades Plant. The review has provided for (1) as assessment of the significance of differences between current technical positions on selected safety issues and those that existed when the Palisades Plant was licensed, (2) a basis for deciding on how these differences should be resolved in an integrated plant review, and (3) a documented evaluation of plant safety when all supplements to the Final IPSAR and the Safety Evaluation Report for converting the license from a provisional to a full-term license have been issued. The report also addresses the comments and recommendations made by the Advisory Committee on Reactor Safeguards in connection with its review of the Draft Report, issued in April 1982

  7. Evaluation of on-line chelant addition dilute chemical cleaning. Final report

    International Nuclear Information System (INIS)

    The on-line addition of chelants (EDTA, HEDTA) was evaluated based on thermostability of the metal chelate at steam generator operating conditions and based upon material compatibility. Testing under prototypical operating conditions in a model steam generator demonstrated the feasibility of this process under various fouling conditions (seawater and freshwater). Application of dilute chemical cleaning to steam generators was also evaluated. Feasibility of this process was demonstrated by its ability to clean packed crevices. However, application times are long and corrosion rates, while acceptable, require additional development of non-sulfur containing inhibitors

  10. The IUE Final Archive -- Scientific Evaluation and Results with NEWSIPS Data

    Science.gov (United States)

    de La Pena, M. D.; Nichols-Bohlin, J.; Levay, K. L.; Michalitsianos, A.

    The culmination of the IUE Project will be the creation of a Final Archive which will contain all scientific and calibration data acquired during the mission, processed in a consistent and homogenous fashion, using an enhanced image processing system designed specifically for this purpose. Fundamental observational and image processing parameters will be incorporated into the headers of the image data files, and compiled into an IUE Project Database, further enhancing the utility of the archival information. Data processed for the Final Archive will begin to be available during 1993. The Final Archive data reduction system, NEW Spectral Image Processing System (NEWSIPS), utilizes innovative image processing techniques in order to achieve an improved signal-to-noise ratio (S/N) in the extracted spectrum. Specifically, NEWSIPS employs: an image registration algorithm and a ``raw space'' Intensity Transfer Function (ITF) which yield a more accurate photometric correction; a flux conserving resampling which maps the data to a geometric space where the echelle orders are parallel to an image axis and the wavelength dispersion is linear within each order; and a signal-weighted extraction method. NEWSIPS achieves a significant increase in the S/N in the two-dimensional images, and ultimately, in the extracted spectra. The increase in the S/N for low-dispersion data ranges from 10 -- 50 percent, with factors of 2 -- 4 improvement in some cases. The greatest improvements have been seen in under-exposed, high radiation, and high sky background images. The S/N for NEWSIPS data is often better than that of the IUESIPS data for a single spectrum, and multiple NEWSIPS images can be co-added to attain further increases in the S/N. Preliminary results from the high-dispersion system suggest a comparable improvement in S/N to that obtained for low-dispersion. Examples of the improvements in the data are presented. The Goddard IUE Project Database will contain the basic

  15. Analysis and evaluation of interwell seismic logging techniques for hydrocarbon reservoir characterization. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Parra, J.O.; Zook, B.J.; Sturdivant, V.R.

    1994-06-01

    The work reported herein represents the third year work in evaluating high-resolution interwell seismic logging techniques for hydrocarbon reservoir characterization. The objective of this project is to investigate interwell seismic logging techniques for indirectly interpreting oil and gas reservoir geology and rock physical properties. The work involves a balanced study of theoretical and numerical modeling of seismic waves transmitted between pairs of wells combined with experimental data acquisition and processing at controlled field conditions. The field applications of this reservoir probing concept are aimed at demonstrating high resolution measurements and detailed interpretation of heterogeneous hydrocarbon-bearing formations. The first part of this third year project efforts was devoted to thoroughly evaluating interwell seismic logging and reverse VSP in a hydrocarbon-bearing formation at the Buckhorn test site in Illinois. Specifically, the data from the experiments conducted in the second year of this project were analyzed to delineate geological structures and to extract rock physical parameters. The second part of this project is devoted to the evaluation of continuity logging techniques for hydrocarbon reservoir continuity. Specifically, this part of the project includes the evaluation of methods of measurements, modeling and data processing to delineate the reservoir architecture and relate dispersion and attenuation measurements to rock physical properties.

    Thor, S.E. [comp.] [National Defence Research Establishment (Sweden)

    1996-11-01

    The main aim of the project was to test and evaluate a new wind power technique, partly through detailed measurements of the NWP 400 and partly through comparisons with the Danish standard unit. At the same time, it was a demand that the two units of the Power Station could be run as a production plant once the evaluation was complete. The overall conclusion from operation, and from the various measurements and studies carried out, is that the new technique functions as intended and that the calculations and estimates made in connection with design work were largely correct. The evaluation confirms that the unit can meet expected production levels, that it can cope with different operation situations and that it can be expected to meet the demands set for loads and safety with regard to fatigue. The evaluation has also shown that the calculation tools used to design the unit and calculate the production capacity have given correct results and good estimates. Certain sub-systems did not, however, function as intended and modifications were required. Additional modifications may be required in a series production of NWP 400. In its present form the unit has difficulties at high wind speeds due to large teeter movements. According to calculations, it should be possible to further reduce these teeter movements and thus increase the availability. The comparison between the units shows that both of the units have largely achieved the expected production capacity. 83 figs, 17 tabs

  5. Decision model for assessment of sandstone uranium deposits. National Uranium Resource Evaluation. Final report

    International Nuclear Information System (INIS)

    The main objective of the National Uranium Resource Evaluation (NURE) program is an estimation of the uranium resources of the United States. To achieve this objective, a geologic evaluation and resource assessment program was initiated using NTMS 20 quadrangles as the basic work unit. The evaluation activity commences with data collection within th 20 quadrangles in order to identify and delineate geologic environments that are favorable for the occurrence of uranium deposits. A favorable environment is depicted as a geologic setting that has the potential for containing at least 100 tons of U3O8 in rocks whose uranium grade exceeds 100 ppM. Geologic field reconnaissance, hydrochemical and stream sediment reconnaissance, aerial radiometric and magnetic surveys, and logging are the principal means by which favorable environments are identified. The principal investigator of each evaluation team is required to classify a favorable environments according to a preliminary classification of uranium occurrences and favorable environments. Based on this information the uranium potential in each quadrangle is estimated. The scope of this study is limited to development of an assessment procedure and a Bayesian decision model for estimating the endowed area A/sub e/ for three sandstone type uranium deposits: Wyoming roll-type, South Texas roll-type, and Uravan/Salt Wash tabular type deposits

  7. Demonstration, testing, and evaluation of in situ heating of soil. Volume 1, Final report

    International Nuclear Information System (INIS)

    This document is a final reports in two volumes. Volume I contains the technical report and Volume II contains appendices with background information and data. In this project approximately 300 cubic yards of clayey soil containing a low concentration plume of volatile organic chemicals was heated in situ by the application of electrical energy. It was shown that as a result of heating the effective permeability of soil to air flow was increased such that in situ soil vapor extraction could be performed. The initial permeability of soil was so low that the soil gas flow rate was immeasurably small even at high vacuum levels. It was demonstrated that the mass flow rate of the volatile organic chemicals was enhanced in the recovered soil gas as a result of heating

    Duplex stainless steels (DSS) are being specified for chloride containing environments due to their enhanced pitting and stress corrosion cracking resistance. They exhibit improved corrosion performance over the austenitic stainless steels. Duplex stainless steels also offer improved strength properties and are available in various wrought and cast forms. Selected grades of duplex stainless steel castings and their welds, in comparison with their wrought counterparts, were evaluated, regarding corrosion performance and mechanical properties and weldability. Multiple heats of cast duplex stainless steel were evaluated in the as-cast, solution annealed (SA) static cast and SA centrifugal cast conditions, while their wrought counterparts were characterized in the SA condition and in the form of as-rolled plate. Welding, including extensive assessment of autogenous welds and a preliminary study of composite welds (shielded metal arc weld (SMAW)), was performed. The evaluations included critical pitting temperature (CPT) testing, intergranular corrosion (IGC) testing, ASTM A923 (Methods A, B and C), Charpy impact testing, weldability testing (ASTM A494), ferrite measurement and microstructural evaluations. In the study, the corrosion performances of DSS castings were characterized and assessed, including the wrought counterparts for comparison. The evaluation filled the pore of lack of data for cast duplex stainless steels compared to wrought materials. A database of the pitting corrosion and IGC behavior of cast and wrought materials was generated for a greater depth of understanding for the behavior of cast duplex stainless steel. In addition, improved evaluation methods for DSS castings were developed according to ASTM A923, A262, G48 and A494. The study revealed that when properly heat treated according to the specification, (1) DSS castings have equal or better pitting and intergranular corrosion resistance than their wrought counterparts; (2) Welding reduces the

    The Spills Working Group was one of six working groups established under the Accident Phenomenology and Consequence (APAC) methodology evaluation program. The objectives of APAC were to assess methodologies available in the accident phenomenology and consequence analysis area and to evaluate their adequacy for use in preparing DOE facility safety basis documentation, such as Basis for Interim Operation (BIO), Justification for Continued Operation (JCO), Hazard Analysis Documents, and Safety Analysis Reports (SARs). Additional objectives of APAC were to identify development needs and to define standard practices to be followed in the analyses supporting facility safety basis documentation. The Spills Working Group focused on methodologies for estimating four types of spill source terms: liquid chemical spills and evaporation, pressurized liquid/gas releases, solid spills and resuspension/sublimation, and resuspension of particulate matter from liquid spills.

  11. Methodology for evaluation of the reliability and safety of interim and final repositories for radioactive waste

    International Nuclear Information System (INIS)

    The methodology is based on a set of macro models, mathematical methods and computer codes describing events and processes of radionuclide migration from the repository to the biosphere and evaluating the exposure doses to the population from the area in case of an emergency scenario. The basic macromodels are: Near Field; Intermediate Field; Far Field and Biosphere. The development and effects of corrosion processes, considering complex corrosion as well as local corrosion, are emphasized. The basic modules in the set of computer codes used are: FEMWATER (Sandia NL, USA) modelling radionuclide migration from the repository; PAGAN, which includes the codes DISPERSE and SURFACE, modelling radionuclide migration by surface waters; and GEN II PRESTO, which evaluates the direct dispersion of radioactivity into the atmosphere by the Gaussian model. On the basis of methodology proposed a qualitative assessment of the safety and reliability of the radwaste repository can be made. 5 figs., 45 refs. (author)

This report contains all of the results derived from the program to evaluate the use of cyclocraft in the support of oil and gas drilling and production operations in wetland areas.

  14. Evaluation of the potential for surface faulting at TA-63. Final report

    International Nuclear Information System (INIS)

    This report describes an investigation of the potential for surface faulting at the proposed sites for the Radioactive Liquid Waste Treatment Facility (RL)WF) and the Hazardous Waste Treatment Facility at TA-63 and TA-52 (hereafter TA-63), Los Alamos National Laboratory (LANL). This study was performed by Woodward-Clyde Federal Services (WCFS) at the request of the LANL. The projections of both the Guaje Mountain and Rendija Canyon faults are mapped in the vicinity of TA-63. Based on results obtained in the ongoing Seismic Hazard Evaluation Program of the LANL, displacement may have occurred on both the Guaje Mountain and Rendija Canyon faults in the past 11,000 years (Holocene time). Thus, in accordance with US Department of Energy (DOE) Orders and Standards for seismic hazards evaluations and the US Environmental Protection Agency (EPA) Resource Conservation and Recovery Act (RCRA) Regulations for seismic standard requirements, a geologic study of the proposed TA-63 site was conducted

  1. Monitoring and Evaluation : Yakima/Klickitat Fisheries Project, Final Report 2000.

    Energy Technology Data Exchange (ETDEWEB)

    Sampson, Melvin R.

    2000-01-01

    The monitoring and evaluation objectives and tasks have been developed through a joint process between the co-managers, Yakama Nation (YN, Lead Agency) and Washington Department of Fish and Wildlife (WDFW). The Science/Technical Advisory Committee (STAC), which consists of core members from the co-managers, employs the services of a work committee of scientists, the Monitoring Implementation Planning Team (MIPT) to develop the Monitoring and Evaluation (M&E) Plan. The process employed by STAC to verify these designated activities and the timing of their implementation involved the utilization of the following principles: (1) YKFP monitoring should evaluate the success (or lack of it) of project supplementation efforts and its impacts, including juvenile post release survival, natural production and reproductive success, ecological interactions, and genetics; (2) YKFP monitoring should be comprehensive: and, (3) YKFP monitoring should be done in such a way that results are of use to salmon production efforts throughout and Columbia basin and the region. Utilizing these principles, STAC and MIPT developed this M&E action plan in three phases. The first phase was primarily conceptual. STAC and MIPT defined critical issues and problems and identified associated response variables. The second phase was quantitative, which determined the scale and size of an effective monitoring effort. A critical element of the quantitative phase was an assessment of the precision with which response variables can be measured, the probability of detecting real impacts and the sample sizes required for a given level of statistical precision and power. The third phase is logistical. The feasibility of monitoring measures was evaluated as to practicality and cost. The Policy Group has determined that the M&E activities covered by this agreement are necessary, effective and cost-efficient.

  2. Improvement and evaluation of methods for sulfate analysis. Part II. Final report Oct 78-May 79

    International Nuclear Information System (INIS)

    Methods for extraction of sulfate from glass-fiber hi-vol and Teflon lo-vol samples were evaluated. Efficiencies were found to vary with sampling location up to 20%. Mechanical shaking in water at room temperature was significantly more efficient than ultrasonic or reflux techniques with hi-vol samples. While Teflon filters are not wet by water, pre-wetting of filters with methanol did not significantly enhance sulfate extraction. A turbidimetric sulfate method using SulfaVer IV was evaluated for ruggedness, precision and intermethod agreement. Its precision was at least equal to that of a conventional turbidimetric method, but its accuracy was somewhat less, especially at lower sulfate levels. The Dionex Model 10 ion chromatograph was evaluated for low level sulfate analysis using both a sample preconcentrator and large (0.5 ml) sample loop. The latter was the preferred technique for samples = or < 20 microgram/ml. Accuracy was within 15% in the range 2 to 20 microgram/ml with a median C.V. of 6.5% for 24 atmospheric samples collected with dichotomous samplers. Use of a sample pre-concentrator permitted analysis of samples containing < 1 microgram/ml sulfate

  3. Evaluation of control technology for the phosphate fertilizer industry. Final report July 1978-June 1979

    Energy Technology Data Exchange (ETDEWEB)

    Boscak, V.G.

    1979-08-01

    The report gives results of a phosphate fertilizer industry study to evaluate multimedia control technology, identify information gaps, and define needed RDandD projects. The following manufacturing processes were covered: wet process phosphoric acid, superphosphoric acid, diammonium phosphate, and normal and triple superphosphate. Air emission control technology, based largely on using wet scrubbers, is adequate for control of fluoride and particulate and is used throughout the industry. The cross-flow packed scrubber appears to be the best and applies to all processes. The gypsum pond appears to be the major environmental concern: main problems are fluoride emissions to the atmosphere and possible leaching of fluoride, phosphate, and radioactive substances. None of the several control alternatives are economically attractive. RDandD projects identified and defined in this study are: (1) an epidemiologic study of the industry; (2) studies of gypsum pond emissions and chemistry; (3) an evaluation and optimization of wet scrubbers; (4) a study of the atmospheric interaction and dispersion modeling of ammonia/sulfuric acid mist; (5) a demonstration of a dry system for fluoride removal; and (6) an evaluation of the Kimre mist eliminator.

    Walkowicz, K.; Lammert, M.; Curran, P.

    2012-08-01

    This 13-month evaluation used five Kenworth T370 hybrid tractors and five Freightliner M2106 standard diesel tractors at a Coca Cola Refreshments facility in Miami, Florida. The primary objective was to evaluate the fuel economy, emissions, and operational field performance of hybrid electric vehicles when compared to similar-use conventional diesel vehicles. A random dispatch system ensures the vehicles are used in a similar manner. GPS logging, fueling, and maintenance records and laboratory dynamometer testing are used to evaluate the performance of these hybrid tractors. Both groups drive similar duty cycles with similar kinetic intensity (0.95 vs. 0.69), average speed (20.6 vs. 24.3 mph), and stops per mile (1.9 vs. 1.5). The study demonstrated the hybrid group had a 13.7% fuel economy improvement over the diesel group. Laboratory fuel economy and field fuel economy study showed similar trends along the range of KI and stops per mile. Hybrid maintenance costs were 51% lower per mile; hybrid fuel costs per mile were 12% less than for the diesels; and hybrid vehicle total cost of operation per mile was 24% less than the cost of operation for the diesel group.

    Ingersoll, D.; Clark, N.H.

    1999-04-01

    In February 1997, under the auspices of the Product Realization Program, an initiative to develop performance models for lithium/manganese dioxide-based batteries began. As a part of this initiative, the performance characteristics of the cells under a variety of conditions were determined, both for model development and for model validation. As a direct result of this work, it became apparent that possible Defense Program (DP) uses for batteries based on this cell chemistry existed. A larger effort aimed at mapping the performance envelope of this chemistry was initiated in order to assess the practicality of this cell chemistry, not only for DP applications, but also for other uses. The work performed included an evaluation of the cell performance as a function of a number of variables, including cell size, manufacturer, current, pulse loads, constant current loads, safety, etc. In addition, the development of new evaluation techniques that would apply to any battery system, such as those related to reliability assessments began. This report describes the results of these evaluations.

    A 30-Mwt prototype sodium-to-sodium intermediate heat exchanger and a 30-Mwt prototype sodium-heated steam generator were tested in combined operation in its Sodium Components Test Installation. This report contains the results of test and evaluation of the steam generator. During plant performance tests, performance degradation was observed, which resulted in the initiation of a diagnostic test series. This test series revealed that under certain operating conditions, the thermohydraulic characteristic of the steam generator changed either suddenly or gradually, resulting in overall performance degradation. A structural failure, requiring retirement of the unit, occurred before the diagnostic test series and analytical support effort were completed. This report describes the thermohydraulic and structural performance, including the structural failures, and related evaluation analyses of the Alco/BLH prototype steam generator performed prior to termination of the test and evaluation program. In addition, the report presents a post-test examination plan to obtain data that could possibly explain the cause of performance anomalies and structural failures experienced during testing.

  7. Final Test and Evaluation Results from the Solar Two Project; TOPICAL

    International Nuclear Information System (INIS)

    Solar Two was a collaborative, cost-shared project between 11 U. S. industry and utility partners and the U. S. Department of Energy to validate molten-salt power tower technology. The Solar Two plant, located east of Barstow, CA, comprised 1926 heliostats, a receiver, a thermal storage system, a steam generation system, and steam-turbine power block. Molten nitrate salt was used as the heat transfer fluid and storage media. The steam generator powered a 10-MWe (megawatt electric), conventional Rankine cycle turbine. Solar Two operated from June 1996 to April 1999. The major objective of the test and evaluation phase of the project was to validate the technical characteristics of a molten salt power tower. This report describes the significant results from the test and evaluation activities, the operating experience of each major system, and overall plant performance. Tests were conducted to measure the power output (MW) of the each major system, the efficiencies of the heliostat, receiver, thermal storage, and electric power generation systems and the daily energy collected, daily thermal-to-electric conversion, and daily parasitic energy consumption. Also included are detailed test and evaluation reports

    1994-08-01

    Herbaceous lignocellulose crops are a potential renewable feedstock for biochemical conversion systems second in size to wood products. Several herbaceous crops are utilized as forage crops in the northern Great Plains, but forage quality considerations usually dictates a early harvest. Biomass cropping does not have this constraint; therefore, little information was available on herbaceous crops utilized as energy crops prior to this project. Our primary objectives were to evaluate the biomass yield and select chemical components of several herbaceous crops for energy crops in the northern Great Plains, compare the economic feasibility of energy crops with common competing crops, and evaluate biomass cropping on summer fallow lands. Three good, two marginal, and one irrigated sites were used during 1988 to 1992 for the first component. At least six perennial and four annual biomass species were included at all sites. Three to four nitrogen (N) levels and a crop-recrop comparison (annuals only) were management intensities included. Biomass cropping on idled lands was performed on dryland at Carrington and evaluated the effects of removing leguminous biomass on fallowed lands. This report summarizes results from the 5-year project.

    1981-08-01

    The objective was to advance the technology for the preparation, storage, handling and combustion of highly-loaded coal/water mixtures. A systematic program to prepare and experimentally evaluate coal/water mixtures was conducted to develop mixtures which (1) burn efficiently using combustion chambers and burners designed for oil, (2) can be provided at a cost less than that of No. 6 oil, and (3) can be easily transported and stored. The program consisted of three principal tasks. The first was a literature survey relevant to coal/water mixture technology. The second involved slurry preparation and evaluation of rheological and stability properties, and processing techniques. The third consisted of combustion tests to characterize equipment and slurry parameters. The first task comprised a complete search of the literature, results of which are tabulated in Appendix A. Task 2 was involved with the evaluation of composition and process variables on slurry rheology and stability. Three bituminous coals, representing a range of values of volatile content, ash content, and hardness were used in the slurries. Task 3 was concerned with the combustion behavior of coal/water slurry. The studies involved first upgrading of an experimental furnace facility, which was used to burn slurry fuels, with emphasis on studying the effect on combustion of slurry properties such as viscosity and particle size, and the effect of equipment parameters such as secondary air preheat and atomization.

    2011-01-01

    This report is provided as part of ITT s NASA Glenn Research Center Aerospace Communication Systems Technical Support (ACSTS) contract NNC05CA85C, Task 7: New ATM Requirements-Future Communications, C-Band and L-Band Communications Standard Development and was based on direction provided by FAA project-level agreements for New ATM Requirements-Future Communications. Task 7 included two subtasks. Subtask 7-1 addressed C-band (5091- to 5150-MHz) airport surface data communications standards development, systems engineering, test bed and prototype development, and tests and demonstrations to establish operational capability for the Aeronautical Mobile Airport Communications System (AeroMACS). Subtask 7-2 focused on systems engineering and development support of the L-band digital aeronautical communications system (L-DACS). Subtask 7-1 consisted of two phases. Phase I included development of AeroMACS concepts of use, requirements, architecture, and initial high-level safety risk assessment. Phase II builds on Phase I results and is presented in two volumes. Volume I is devoted to concepts of use, system requirements, and architecture, including AeroMACS design considerations. Volume II (this document) describes an AeroMACS prototype evaluation and presents final AeroMACS recommendations. This report also describes airport categorization and channelization methodologies. The purposes of the airport categorization task were (1) to facilitate initial AeroMACS architecture designs and enable budgetary projections by creating a set of airport categories based on common airport characteristics and design objectives, and (2) to offer high-level guidance to potential AeroMACS technology and policy development sponsors and service providers. A channelization plan methodology was developed because a common global methodology is needed to assure seamless interoperability among diverse AeroMACS services potentially supplied by multiple service providers.

  11. Evaluative studies in nuclear medicine research: positron computed tomography assessment. Final report, January 1, 1982-December 31, 1982

    International Nuclear Information System (INIS)

    Results are reported of the final phase of the study effort generally titled Evaluative Studies in Nuclear Medicine Research. The previous work is reviewed and extended to an assessment providing perspectives on medical applications of positron emission tomographic (PET) systems, their technological context, and the related economic and marketing environment. Methodologies developed and used in earlier phases of the study were continued, but specifically extended to include solicitation of opinion from commercial organizations deemed to be potential developers, manufacturers and marketers of PET systems. Several factors which influence the demand for clinical uses of PET are evaluated and discussed. The recent Federal funding of applied research with PET systems is found to be a necessary and encouraging event toward a determination that PET either is a powerful research tool limited to research, or whether it also presents major clinical utility. A comprehensive, updated bibliography of current literature related to the development, applications and economic considerations of PET technology is appended

  13. Risk Evaluation for CO2 Geosequestration in the Knox Supergroup, Illinois Basin Final Report

    Energy Technology Data Exchange (ETDEWEB)

    Hnottavange-Telleen, Ken; Leetaru, Hannes

    2014-09-30

    This report describes a process and provides seed information for identifying and evaluating risks pertinent to a hypothetical carbon dioxide (CO2) capture and sequestration (CCS) project. In the envisioned project, the target sequestration reservoir rock is the Potosi Formation of the Knox Supergroup. The Potosi is identified as a potential target formation because (1) at least locally, it contains vuggy to cavernous layers that have very high porosity, and (2) it is present in areas where the deeper Mt. Simon Sandstone (a known potential reservoir unit) is absent or nonporous. The key report content is discussed in Section 3.3, which describes two lists of Features, Events, and Processes (FEPs) that should be considered during the design stage of such a project. These lists primarily highlight risk elements particular to the establishment of the Potosi as the target formation in general. The lists are consciously incomplete with respect to risk elements that would be relevant for essentially all CCS projects regardless of location or geology. In addition, other risk elements specific to a particular future project site would have to be identified. Sources for the FEPs and scenarios listed here include the iconic Quintessa FEPs list developed for the International Energy Agency Greenhouse Gas (IEAGHG) Programme; previous risk evaluation projects executed by Schlumberger Carbon Services; and new input solicited from experts currently working on aspects of CCS in the Knox geology. The projects used as sources of risk information are primarily those that have targeted carbonate reservoir rocks similar in age, stratigraphy, and mineralogy to the Knox-Potosi. Risks of using the Potosi Formation as the target sequestration reservoir for a CCS project include uncertainties about the levels of porosity and permeability of that rock unit; the lateral consistency and continuity of those properties; and the ability of the project team to identify suitable (i.e., persistently

    1997-10-01

    This final report presents detection thresholds, detection probabilities, and location error ellipse projections for the US National Seismic Network (USNSN) with and without real-time cooperative stations in the eastern US. Network simulation methods are used with spectral noise levels at stations in the USNSN and other stations to simulate the processes of excitation, propagation, detection, and processing of seismic phases. The USNSN alone should be capable of detecting 4 or more P waves for shallow crustal earthquakes in nearly all of the eastern and central US at the magnitude 3.8 level. When real-time cooperative stations are used in conjunction with the USNSN, the network should be capable of detecting 4 or more P waves from events 0.2 to 0.3 magnitude units lower. The planned expansion of the USNSN and cooperative stations should improve detection levels by an additional 0.2 to 0.3 magnitudes units in many areas. Location uncertainties for the USNSN should be significantly improved by addition of real-time cooperative stations. Median error ellipses for magnitude 4.5 earthquakes in the eastern and central US depend strongly upon location, but uncertainties should be less than 100 square km in the central US and degrade to 200 square km or more offshore and to the south and north of the international boundaries. Close cooperation with the Canadian National Network should substantially improve detection thresholds and location uncertainties along the Canadian border.

  15. Evaluation and design of geophysical monitoring network for ground-water contamination. Final report

    International Nuclear Information System (INIS)

    Ground water contamination has emerged as one of the Nation's primary environmental concerns. Reliable, rapid and cost-effective detection and remedial action can contribute to minimizing the adverse environmental and economic impacts of ground water contamination. The report contributes to aquifer remediation by developing a set of planning tools for detection, mapping, monitoring and remediation of contaminated aquifers. The report is divided into three main sections that correspond to a typical sequence of actions resulting in a final remedial action plan for handling contamination at a particular site. The first section develops a methodology for detecting and mapping suspected contamination using multiple sources of data. A decision support system for observation network design is presented in the second section. Network design is approached from a multiple objective decision making perspective. The objective is to identify the preferred network design while considering the trade-off between performance and cost. A remedial action design support system is described in the third section. Three dimensional geostatistical simulation and analytical ground water modeling are used to assess the need for further remedial action planning. Each of the methods developed in the report have been demonstrated using data collected from the site of a low-level radioactive industrial waste reprocessing facility near Wood River Junction, Rhode Island

  16. Evaluation of dry-solids-blend material source for grouts containing 106-AN waste: Final report

    International Nuclear Information System (INIS)

    Stabilization/solidification technology is one of the most widely used techniques for the treatment and ultimate disposal of both radioactive and chemically hazardous wastes. Cement-based products, commonly referred to as grouts, are the predominant materials of choice because of their low associated processing costs, compatibility with a wide variety of disposal scenarios, and ability to meet stringent processing and performance requirements. Such technology is being utilized in a Grout Treatment Facility (GTF) by the Westinghouse Hanford Company (WHC) for the disposal of various wastes, including 106-AN wastes, located on the Hanford Reservation. The WHC personnel have developed a grout formula for 106-AN disposal that is designed to meet stringent performance requirements. This formula consists of a dry-solids blend containing 40 wt % limestone, 28 wt % granulated blast furnace slag (BFS), 28 wt % American Society for Testing and Materials (ASTM) Class F fly ash, and 4 wt % Type I-II-LA Portland cement. This blend is mixed with 106-AN at a mix ratio of 9 lb of dry-solids blend per gallon of waste. This report documents the final results of efforts at Oak Ridge National Laboratory in support of WHC's Grout Technology Program to assess the effects of the source of the dry-solids-blend materials on the resulting grout formula

    1992-04-01

    The feasibility of silicon nitride (Si{sub 3}N{sub 4}) use in internal combustion engines was studied by testing three different components for wear resistance and lower reciprocating mass. The information obtained from these preliminary spin rig and engine tests indicates several design changes are necessary to survive high-stress engine applications. The three silicon nitride components tested were valve spring retainers, tappet rollers, and fuel pump push rod ends. Garrett Ceramic Components` gas-pressure sinterable Si{sub 3}N{sub 4} (GS-44) was used to fabricate the above components. Components were final machined from densified blanks that had been green formed by isostatic pressing of GS-44 granules. Spin rig testing of the valve spring retainers indicated that these Si{sub 3}N{sub 4} components could survive at high RPM levels (9,500) when teamed with silicon nitride valves and lower spring tension than standard titanium components. Silicon nitride tappet rollers showed no wear on roller O.D. or I.D. surfaces, steel axles and lifters; however, due to the uncrowned design of these particular rollers the cam lobes indicated wear after spin rig testing. Fuel pump push rod ends were successful at reducing wear on the cam lobe and rod end when tested on spin rigs and in real-world race applications.

    1998-05-01

    The PICHTR Sustainable Biomass Energy Program was developed to evaluate the potential to cultivate crops for energy production as an alternative use of lands made available by the closing of large sugar plantations. In particular, the closing of the Hamakua Sugar Company on the island of Hawaii brought a great deal of attention to the future of agriculture in this region and in the state. Many options were proposed. Several promising alternatives had been proposed for cane lands. These included dedicated feedstock supply systems (DFSS) for electrical energy production, cultivation of sugarcane to produce ethanol and related by-products, and the production of feed and crops to support animal agriculture. Implementation of some of the options might require preservation of large tracts of land and maintenance of the sugar mills and sugar infrastructure. An analysis of the technical, financial, and other issues necessary to reach conclusions regarding the optimal use of these lands was required. At the request of the Office of State Planning and Senator Akaka`s office, the Pacific International Center for High Technology Research (PICHTR) established and coordinated a working group composed of state, county, federal, and private sector representatives to identify sustainable energy options for the use of idle sugar lands on the island of Hawaii. The Sustainable Biomass Energy Program`s Hamakua Project was established to complete a comprehensive evaluation of the most viable alternatives and assess the options to grow crops as a source of raw materials for the production of transportation fuel and/or electricity on the island of Hawaii. The motivation for evaluating biomass to energy conversion embraced the considerations that Hawaii`s energy security would be improved by diversifying the fuels used for transportation and reducing dependency on imported fossil fuels. The use of waste products as feedstocks could divert wastes from landfills.

  1. TRUPACT insulation evaluation. Acurex final report FR-82-10/ATD

    International Nuclear Information System (INIS)

    This report summarizes the results of a combined experimental and analytical study to define the best wall insulation for TRUPACT applications from among commercially available polyurethane foam materials. Screening tests were conducted for eleven candidate foam materials to evaluate their basic performance characteristics. From these results, three materials were selected for further investigation via mockup wall-fire simulation tests. On the basis of these data, Sandia selected General Plastics' FR-9606 as the primary insulation material for TRUPACT prototype design. Both charring and noncharring analytical thermal models were developed for FR-9606 to support TRUPACT design analysis. 13 references, 77 figures, 14 tables

  4. Developing an inventor support service which performs early stage market and manufacturing evaluations. [Final Report

    Energy Technology Data Exchange (ETDEWEB)

    1991-10-01

    American businesses are learning the difficult high cost lesson of ignoring production and market factors (producibility, unit product cost (UPC), marketability, etc) during the engineering design phase of product development. Studies have shown that the Japanese spend three times as long as Americans in the design feasibility and decision process of new product introductions and one third the amount of time in the implementation of those products. There is a 20 to 1 cost benefit on effort applied in the design phase versus the production phase of the product life cycle. The number one goal of this project was to establish an organization that has, as one of its purposes, the providing of services responsive to the needs of independent inventors. The number two goal was to demonstrate the value of providing marketing and manufacturing counsel at an early stage in the product development process. The first study goal was met by providing the materials and information necessary to establish an evaluation team and an organization to handle such evaluations. The second study goal was met by demonstrating the impact of early market analysis and manufacturing considerations on product design and therefore on the description of the invention for four different inventions. These inventions were selected at various stages of development. Regardless of stage of development, the marketing and manufacturing reviews resulted in significant changes in design and/or market positioning.

    One significant component of the waste stream, discarded plastic products and packaging, continues to be a growing portion of the municipal solid waste (MSW). There has been considerable work done in characterizing the quantity and types of plastics in different waste streams, collection methods, separation, sorting as well as technologies for processing post-consumer mixed plastics. The focus in recent years has been the development of markets for recycled plastic products, which constitutes the second half of the material flow diagram cycle shown in Figure 1. One key product that holds significant promise for plastics recycling to be both technically feasible and economically viable is Recycled Plastic Lumber (RPL). The contents of this report forms the second phase of a two-phase pilot project on developing specifications and standards for a product fabricated from RPL. Such standards and specifications are needed to prepare procurement guidelines for state and federal agencies interested in purchasing products made from recycled materials. The first phase focused on establishing a procedure to evaluate RPL product,s such as pallets, in a laboratory setting while this phase focuses on field evaluation of RPL pallets in service. This effort is critical in the development of new markets for RPL products. A brief summary of the findings from Phase 1 of this effort is presented next.

    This report describes testing and evaluation performed by the Environmental Laboratory of the US Army Engineer Waterways Experiment Station on sediment from the turning basin of Oakland Inner Harbor, Oakland, CA. Test protocols from the Corps' Management Strategy for Disposal of Dredged Material were used in the present evaluation to determine the potential for migration of contaminants into effluent, surface runoff, leachates, plants, and animals at an upland disposal site. Two sediments from the turning basin of Oakland Inner Harbor were tested: a composite sample of cores taken from the surface to 38-ft depth (upper sediment) and a composite sample of cores taken from 38- to 45-ft depth (lower sediment). In addition, two potential disposal site soils were tested: Twitchell Island and 7th Street disposal site. Sediment characterization indicated that the Oakland upper sediment contained higher concentrations of most contaminants than the lower sediment. Metal concentrations in the Oakland lower sediment were in the range of values found at the Twitchell Island disposal site. The Oakland upper sediment contained levels of cadmium and arsenic similar to those in Twitchell Island levee soils, but higher levels of zinc, nickel, lead, and copper....

    The results are presented of processing plant evaluations of the St. Louis-Union Electric Refuse Fuel Project, including equipment and facilities as well as assessment of environmental emissions at both the processing and the power plants. Data on plant material flows and operating parameters, plant operating costs, characteristics of plant material flows, and emissions from various processing operations were obtained during a testing program encompassing 53 calendar weeks. Refuse derived fuel (RDF) is the major product (80.6% by weight) of the refuse processing plant, the other being ferrous metal scrap, a marketable by-product. Average operating costs for the entire evaluation period were $8.26/Mg ($7.49/ton). The average overall processing rate for the period was 168 Mg/8-h day (185.5 tons/8-h day) at 31.0 Mg/h (34.2 tons/h). Future plants using an air classification system of the type used at the St. Louis demonstration plant will need an emissions control device for particulates from the large de-entrainment cyclone. Also in the air exhaust from the cyclone were total counts of bacteria and viruses several times higher than those of suburban ambient air. No water effluent or noise exposure problems were encountered, although landfill leachate mixed with ground water could result in contamination, given low dilution rates.

    1985-03-01

    Research was undertaken to develop a method of evaluating reservoirs as prospects for carbon dioxide flooding. Evaluation was to be based on a determination of miscibility pressure and displacement efficiency under idealized conditions. To reach the objective, project work was divided into five areas: (1) conducting of phase-equilibrium studies of carbon dioxide with synthetic oils; (2) application of an equation of state to simulate the phase behavior of carbon dioxide - oil systems; (3) conducting of linear displacements of crude oils and synthetic oils by carbon dioxide in a slim-tube apparatus; (4) application of the equation of state, the phase-behavior data and slim-tube data to develop a method of screening reservoirs for carbon dioxide flooding based on determination of minimum miscibility pressure and displacement efficiency; (5) development of a one-dimensional mathematical model, based on the equation of state, for application in conjunction with the results of Parts 1 to 4. The accomplishments for these five areas are discussed in five chapters. 44 references, 90 figures, 42 tables.

    The release of the new realization of the International Terrestrial Reference Frame - ITRF2014 was already evaluated in its preliminary form and found to be a significant improvement over previous TRFs. The International Laser Ranging Service (ILRS) contributes unique information that only Satellite Laser Ranging - SLR is sensitive to: the definition of the origin, and in equal parts with VLBI, the scale of the model. For the development of ITRF2014, the ILRS analysts adopted a revision of the internal standards and procedures in generating our contribution from the eight ILRS Analysis Centers. The improved results for the ILRS components were reflected in the resulting new time series of the ITRF origin and scale, showing insignificant trends and tighter scatter. The reanalyzed SLR data on the basis of ITRF2014 are now used to evaluate the individual station performance for the entire ILRS network, focusing on improved estimates of persistent systematic errors over significant periods of time, in hopes of an improved a priori model to be used in the next realization of the ITRF. SLR data beyond what is included in the development of the ITRF and especially from lower altitude missions are used to validate the performance of the model (using e.g. STARLETTE, AJISAI and LARES data). This presentation will focus on the resulting model for persistent systematics and its effect on the ITRF development, using exclusively ILRS tracking data and other ILRS products.

  11. Evaluation of the Dutch National Research Programme on Global Air Pollution and Climate Change. Final Report

    International Nuclear Information System (INIS)

    During 2001, the second phase of the National Research Programme on Global Air Pollution and Climate Change (NOP2) has been evaluated. In the period 1995-2001 the budget for NOP was 47 million Dutch guilders, which supported over 30 organisations in 100 projects and studies spanning four main themes: (1) dynamics of the climate system and its component parts; (2) vulnerability of natural and societal systems to climate change; (3) societal causes and solutions; (4) integration and assessment. Later in the life of the programme, two themes were added to widen the scope of the programme and add value to existing activities. These covered projects concerned with 'cross-cutting' or 'over-arching' issues and those dealing with 'internationalisation', i.e. projects specifically designed to support various initiatives in the development of international programmes. A further proportion of the research budget was dedicated to direct policy support. The evaluation was primarily intended to: Assess the scientific quality of the work undertaken in the programme and the attainment of scientific and technical goals. Also attention was paid to the relevancy of projects and project outputs to national and international policy formulation (policy relevance); the structure and operation of the programme to see if it promoted coherence and synergy between the constituent parts (synergy); and recommendations concerning the form, content and direction of a new programme in the area (new directions)

  12. Evaluation procedure for simulation facilities certified under 10 CFR 55: Final report

    International Nuclear Information System (INIS)

    This document describes the procedure to be followed by the NRC for the inspection of simulation facilities certified by facility licensees under 10 CFR 55. Inspections are divided into four major areas based on the types of evaluations conducted: (1) performance testing; (2) physical fidelity/human factors; (3) control capabilities; and (4) design, updating, modification, and testing. NRC staff representing several disciplines including license examiners, operations specialists, and human factors experts, under the direction of a team leader, will perform these inspections. A simulation facility inspection may include off-site and on-site phases. The off-site phase will consist of an examination of the simulation facility documentation and an identification of those operations and procedures which may be considered for use in performance testing during the on-site phase. In the on-site review, the staff will work closely with the facility licensee to conduct a sound and fair inspection and to evaluate the results of tests that are conducted. Inspection findings will be based upon the staff's judgment of the simulation facility's compliance with 10 CFR 55.45. Findings may range from one of ''no adverse impact on the conduct of operating tests'' through degrees of ''adverse impact requiring correction'' to ''adverse impacts so serious that the simulation facility may not be used in the conduct of operating tests until the discrepancies are corrected and the simulation facility is recertified to the NRC.''

    1980-03-01

    The State Energy Conservation Program was established in 1975 to promote energy conservation and to help states develop and implement their own conservation programs. Base (5) and supplemental (3) programs required states to implement programs including: mandatory thermal-efficiency standards and insulation requirements for new and renovated buildings; mandatory lighting efficiency standards for public buildings; mandatory standards and policies affecting the procurement practices of the state and its political subdivisions; program measures to promote the availability and use of carpools, vanpools, and public transportation; a traffic law or regulation which permits a right turn-on-red; and procedures to carry out a continuing public education effort to increase awareness of energy conservation; procedures which promote effective coordination among local, state, and Federal energy conservation programs; and procedures for carrying out energy audits on buildings and industrial plants. All 50 states and Puerto Rico, Guam, the Virgin Islands, American Samoa, and the District of Columbia participated in the program. The total 1980 energy savings projected by the states is about 5.9 quadrillion Btu's or about 7% of the DOE projected 1980 baseline consumption of just under 83 quads. The detailed summary is presented on the following: information the SECP evaluation; DOE response to the SECP; DOE's role in the program management process; the effectiveness of the states in managing the SECP; the status of program measure implementation; innovative state energy conservation programs; and the evaluation methodology.

    1977-06-30

    The results of tests performed to evaluate the performance of selected high-speed flywheel bearings and shaft seals are reported, and work performed on the development of a high-speed composite flywheel rotor is described. The overall program objective is to develop a composite flywheel system for primary energy storage in a flywheel powered vehicle. These initial tests were intended to evaluate the performance of full-size composite rotor elements, high-speed bearings and shaft seals for that system under conditions simulating as closely as possible those anticipated in a finished vehicle. Performance of the angular contact ball bearings is reported to be satisfactory at all speeds; a simplified lubrication system is recommended for second generation hardware. Performance of the ferrofluidic shaft seals is reported to be marginal, as they failed to hold a hard vacuum at the maximum design speed. Several concepts for improved seals are offered for second generation hardware. The test objectives for the high-speed composite flywheel rotor were not achieved due to dynamic instability problems with the test hardware. Recommendations are offered for the design of second generation hardware, and a scope of activities is proposed for the second phase of this program.

    The point of departure was the statement that people find public transport buses highly polluting. A lot of attention went to the advantages and the disadvantages of buses and trucks on liquefied petroleum gas (LPG) and natural gas. These fuels don`t cause any particle emissions from the combustion process. To quantify the other environmental advantages of gas technology, the Flemish Institute for Technological Research (VITO) carried out measurements of different bus technologies. Fuel consumption, emission of nitrogen oxides, carbon monoxides and hydrocarbons of 8 buses were measured in the Brussels traffic. 3 technologies of the early nineties were taken as a reference: the Euro-1 diesel, the current Brussels public transport company natural gas bus and a LPG bus. Comparisons were made with the modern diesel bus (Euro-2) and the newest buses on natural gas and LPG. To achieve minimal emissions, the best available technology for buses on natural gas or LPG is multipoint injection, the constructors of engines for heavy-duty traffic are changing from carburetor to fuel injection. The best available gas technologies has emissions that can be 50 to 95 per cent lower than the most modern diesel bus. Users mentioned problems at the introduction of vehicles on gas, such as lower reliability and availability. The cost price continues to be a disadvantage of buses and trucks on gas. The extra consumption of fuel doesn`t necessarily imply higher costs. Often fuel suppliers and distributors offer a favourable unit price, which includes the cost for the infrastructure. The purchase price of the vehicle remains higher and the workplaces must be adjusted for maintenance and repairs of vehicles on gas. The bus or truck on diesel is very reliable and cheaper to use than a similar vehicle on gas. The environmental perspectives are much less marked. Heavy-duty traffic emits nitrogen oxides and particles. With respect to these harmful substances in particular, constructors must

    The research project `Evaluation of Anthropogenic Urban Soils` was subsidized by the German Federal Ministry of Education, Science, Research and Technology and adviced by the working group `Stadtboeden` of the German Society of Soil Science. It was realized as a cooperation between the universities of Berlin (TU), Halle-Wittenberg, Hohenheim, Kiel and Rostock and had three objectives: - to characterize soils developed from anthropogenic substratums (`urban soils`), - to figure out distribution patterns of such soils and - to verify whether urban soils could be evaluated according to their filtering and habitat function in the same way as soils developed from natural parent material. Evaluation methods based on easily obtainable field data had to be adapted to `urban soils` respectively developed anew. For that reason some typical soils of anthropogenic lithogenesis had to be examined between 1993 and 1996 both on their importance as habitats for plants and soil organisms and on their filtering, buffering and transforming capacities for organic and inorganic pollutants. Accordingly representative `urban soils` were gathered in the towns of Berlin, Eckernfoerde, Essen, Halle, Kiel, Rostock and Stuttgart; these soils had developed from technogenic substratums (brick and mortar debris, municipal waste, ashes, slag, sludge) and redeposited alkaline resp. acidic natural substratums (mud, coal mine and coking plant deposits). Some of the soils were influenced by ground water, and all soils developed from the same kind of parent material belonged to different stages of development. (orig./SR) [Deutsch] Ziele des vom BMBF gefoerderten und vom Arbeitskreis Stadtboeden der Deutschen Bodenkundlichen Gesellschaft beratenen Verbundprojektes `Bewertung anthropogener Stadtboeden` waren die Charakterisierung von Boeden anthropogener Substrate, die exemplarische Ermittlung des Verteilungsmusters derartiger Boeden und die Pruefung, inwieweit sie sich aehnlich den Boeden natuerlicher

    International Nuclear Information System (INIS)

    In the frame of seismic evaluation of the Kozloduy nuclear power plant units 5 and 6, the region of the spray ponds was investigated because they are of great importance for proper functioning of the NPP in case of an accident. Spray pond is a water containing structure designed for creating a temperature drop of the circulating cooling water in case of an accident in the technical water supply. The region of the spray ponds is well studied in regard to geology and this enabled full-size investigation of the on the liquefaction potential of water saturated sands. In this In this study, three kinds of procedures were applied for estimating the liquefaction potential of water saturated sands. The results obtained were compared, analyzed and conclusions concerning liquefaction potential of water saturated sands drawn

    On July 1--2, 1997, Sandia National Laboratories hosted the External Committee to Evaluate Sandia`s Risk Expertise. Under the auspices of SIISRS (Sandia`s International Institute for Systematic Risk Studies), Sandia assembled a blue-ribbon panel of experts in the field of risk management to assess their risk programs labs-wide. Panelists were chosen not only for their own expertise, but also for their ability to add balance to the panel as a whole. Presentations were made to the committee on the risk activities at Sandia. In addition, a tour of Sandia`s research and development programs in support of the US Nuclear Regulatory Commission was arranged. The panel attended a poster session featuring eight presentations and demonstrations for selected projects. Overviews and viewgraphs from the presentations are included in Volume 1 of this report. Presentations are related to weapons, nuclear power plants, transportation systems, architectural surety, environmental programs, and information systems.

    International Nuclear Information System (INIS)

    Using National Uranium Resource Evaluation criteria, the Raton Quadrangle (New Mexico and Colorado) contains one environment favorable for uranium deposits, the permeable arkosic sandstone members of the Pennsylvanian-Permian Sangre de Cristo Formation for either peneconcordant or roll-type deposits. The favorable parts of the Sangre de Cristo lie mostly in the subsurface in the Raton and Las Vegas Basins in the eastern part of the quadrangle. An area in the Costilla Peak Massif was investigated for uranium by determining geochemical anomalies in stream sediments and spring waters. Further work will be required to determine plutonic environment type. Environments unfavorable for uranium deposits include the Ogallala, Raton, and Vermejo Formations, the Trinidad Sandstone, the Pierre Shale, the Colorado Group, the Dakota Sandstone, the Morrison Formation, the Entrada and Glorieta Sandstones, Mississippian and Pennsylvanian rocks, quartz-pebble conglomerates, pegmatities, and Tertiary granitic stocks

    The emergence more and more constant of non-linear loads in the power systems, with the consequent distortion in the voltage wave forms and of current, turns necessary complementary analyses in the planning of the systems, in way the if understands and to minimize the effects caused by the harmonic distortions. Among the methods used in this analysis are the computational programs that determine the flow of harmonic current and the voltages distorted in the buses. The objective of this work is the optimization of a program developed for large computers, turning possible its utilization in microcomputers. Besides, several models of components and two electric systems have its answers to the presence of multiple frequencies of the fundamental (harmonic frequency) evaluated and the results of the simulations will be presented. It also accomplishes simulations that make possible the visualization of the distortions in the voltage wave forms of the buses. Finally, the work offers a global and qualitative vision of this phenomenon that has been reason increasing preoccupation for mainly among the responsible for the quality of the supplied energy.

  2. A Very Different Non-Stressful Comprehensive Final Exam that Achieve Our Goals for Student Evaluation and Learning

    2015-08-01

    I will introduce the radical concept of a final exam where the questions are given beforehand, a method I first encountered as a graduate student at Princeton University from an outstanding and well known astrophysicist and exceptional teacher, Lyman Spitzer.Every Instructor aspires for students to master all the material covered. A comprehensive final can assess the breadth and depth of their learning. Students are required to review early material in light of later topics, create connections and integrate understanding, thus retaining knowledge for the long term. Comprehensive finals can therefore be a significant basis for student learning and evaluation, but are especially daunting for non-STEM majors in required GE synthesis STEM classes. The exam format proposed here calmed student fears and encouraged thorough review.Ten days before the exam students received 20-30 challenging, well-crafted, numbered questions that interconnected and spanned the entire range of topics. The key is crafting questions that lead to deeply understanding the subject matter and mastering skills to solve problems. At the final, each student was required to pick a number out of a hat and answer that numbered question in a 5-minute presentation. They also had to critically comment on 10 other presentations of their peers. They are graded equally on both.The exam sets up definite goals for a student. Equally important, it enhances collaborative learning and peer mentoring. The conceptual questions and problems that students are required to answer can be studied together in study groups. The final presentation is theirs and they are not only encouraged but required to be constructively critical of their peer presentations.I will provide examples of some of the conceptual and problem solving questions I used. These were crafted to interconnect and span the entire range of topics. This method requires students to be prepared for all of the multitude of crafted question encouraging

  3. Evaluation of uncertainties in irradiated hardware characterization: Final report, September 30, 1986-March 31, 1987

    International Nuclear Information System (INIS)

    Waste Management Group, Inc. has evaluated the techniques used by industry to characterize and classify irradiated hardware components for disposal. This report describes the current practices used to characterize the radionuclide content of hardware components, identifies the uncertainties associated with the techniques and practices considered, and recommends areas for improvement which could reduce uncertainty. Industry uses two different characterization methods. The first uses a combination of gamma scanning, direct sampling, underwater radiation profiling and radiochemical analysis to determine radionuclide content, while the second uses a form of activation analysis in conjunction with underwater radiation profiling. Both methods employ the determination of Cobalt 60 content, and the determination of scaling factors for hard-to-detect Part 61 radionuclides. The accurate determination of Cobalt-60 is critical since the Part 61 activation product radionuclides which affect Part 61 classification are scaled from Cobalt-60. Current uncertainties in Cobalt-60 determination can be reduced by improving underwater radiation profiling equipment and techniques. The calculational techniques used for activation analysis can also be refined to reduce the uncertainties with Cobalt-60 determination. 33 refs., 11 figs., 10 tabs

    After the accident of Three Mile Island, Unit 2, nuclear power plant owners made a number of improvements to their nuclear facilities. Despite these improvements, the US Nuclear Regulatory Commission (NRC) staff is concerned that the number and complexity of events at Babcock and Wilcox (B and W) nuclear plants have not decreased as expected. This concern was reinforced by the June 9, 1985 total-loss-of-feedwater event at Davis-Besse Nuclear Power Station and the December 26, 1985 overcooling transient at Rancho Seco Nuclear Generating Station. By letter dated January 24, 1986, the Executive Director for Operations (EDO) informed the Chairman of the B and W Owners Group (BWOG) that a number of recent events at B and W-designed reactors have led the NRC staff to conclude that the basic requirements for B and W reactors need to be reexamined. In its February 13, 1986 response to the EDO's letter, the BWOG committed to lead an effort to define concerns relative to reducing the frequency of reactor trips and the complexity of post-trip response in B and W plants. The BWOG submitted a description of the B and W program entitled ''Safety and Performance Improvement Program'' (BAW-1919) on May 15, 1986. Five revisions to BAW-1919 have also been submitted. The NRC staff has reviewed BAW-1919 and its revisions and presents its evaluation in this report. 2 figs., 34 tabs

    The objective of this work is to develop and apply a method for research planning for advanced process technologies. To satisfy requirements for research planning, it is necessary to: (1) identify robust solutions to process design questions in the face of uncertainty to eliminate inferior design options; (2) identify key problem areas in a technology that should be the focus of further research to reduce the risk of technology failure; (3) compare competing technologies on a consistent basis to determine the risks associated with adopting a new technology; and (4) evaluate the effects that additional research might have on comparisons with conventional technology. An important class of process technologies are electric power plants. In particular, advanced clean coal technologies are expected to play a key role in the energy and environmental future of the US, as well as in other countries. Research planning for advanced clean coal technology development is an important part of energy and environmental policy. Thus, the research planning method developed here is applied to case studies focusing on a specific clean coal technology. The purpose of the case studies is both to demonstrate the research planning method and to obtain technology-specific conclusions regarding research strategies.

    Lammert, M.; Walkowicz, K.

    2012-09-01

    A parallel hybrid-electric diesel delivery van propulsion system was evaluated at a UPS facility in Minneapolis using on-vehicle data logging, fueling, and maintenance records. Route and drive cycle analysis showed different duty cycles for hybrid vs. conventional delivery vans; routes were switched between the study groups to provide a valid comparison. The hybrids demonstrated greater advantage on the more urban routes; the initial conventional vans' routes had less dense delivery zones. The fuel economy of the hybrids on the original conventional group?s routes was 10.4 mpg vs. 9.2 mpg for the conventional group on those routes a year earlier. The hybrid group's fuel economy on the original hybrid route assignments was 9.4 mpg vs. 7.9 mpg for the conventional group on those routes a year later. There was no statistically significant difference in total maintenance cost per mile or for the vehicle total cost of operation per mile. Propulsion-related maintenance cost per mile was 77% higher for the hybrids, but only 52% more on a cost-per-delivery-day basis. Laboratory dynamometer testing demonstrated 13%-36% hybrid fuel economy improvement, depending on duty cycle, and up to a 45% improvement in ton-mi/gal. NOx emissions increased 21%-49% for the hybrids in laboratory testing.

    1977-01-01

    An analytical study was undertaken to estimate the present and potential technical and economic characteristics of a wide range of components and complete systems capable of converting industrial and commercial waste heat into mechanical or electrical power and/or building and process heating and cooling. The component and system technologies evaluated include: Rankine-, Stirling-, and Brayton-cycle power systems; reciprocating-, rotary-, and turbo-expanders; heat exchangers and heat pumps; thermally driven cooling and dehumidification systems; and integrated systems capable of providing multiple outputs. Extensive analyses were conducted of Rankine-cycle systems using steam, halogenated hydrocarbons, and other organic compounds as working fluids. Performance characteristics, recoverable output power, and installed costs were estimated and are presented herein for Rankine-cycle systems utilizing selected working fluids over a range of waste heat source temperatures between approximately 200 and 1000/sup 0/F. Data describing the performance capabilities, technology and installed costs of heat exchangers, expanders and thermally driven absorption, vapor compression, steam-jet cooling and refrigeration systems are presented herein together with limited performance and cost estimates for Stirling-cycle power recovery systems. The component and system data were used to provide a preliminary assessment of the recoverable energy and associated system costs when integrated with generalized waste heat sources identified by Drexel University from their two-digit SIC industrial energy survey.

  9. Evaluation of new nuclear density gauges on asphalt concrete. Final report, Oct 87-Jun 90

    International Nuclear Information System (INIS)

    The report documents an evaluation of the state-of-the-art capabilities of nuclear density gauges to monitor the density of asphalt concrete. In particular, providing immediate information on compaction by the use of roller-mounted gauges and measuring the densities of thin layers were addressed. The study included three phases: literature search, laboratory tests, and field trials. The first phase included a review of current literature on the theory and operating characteristics of commercially available equipment and a review of State highway agency procedures and specifications for monitoring asphalt concrete density. The second phase included a series of laboratory tests to verify factory calibrations and to determine the depth sensitivity, chemical composition errors, and thin-lift capabilities of the various gauges under laboratory conditions. The third phase consisted of five sets of field trials. The data show that, within limitations, static nuclear gauges can be used for acceptance testing of thin-lifts, but only when all parameters affecting the measurements are precisely known. The dynamic gauges can be effectively used to monitor relative density growth

  10. Evaluation of NASA's Launch Processing System for nuclear power applications: Final report

    International Nuclear Information System (INIS)

    The Space Shuttle Launch Processing System (LPS) automation technology is developed by NASA for the support of the shuttle launch control process. The LPS is based on a software package composed of a high-level real-time programming language and the associated control logic and the user interface facilities. The primary mission of the LPS is to prevent hazardous manual intervention and to allow automatic reaction to out of tolerance events. It also supports interactive and automated control techniques and provides graphical displays for monitoring and control tasks. The LPS programming language includes rule-based capabilities to monitor data, to initiate control actions, and to override operator actions which are inconsistent with the rule set. The NASA's Space Shuttle Launch Processing System has been demonstrated to Nuclear Regulatory Commission (NRC) for an application to nuclear power plant. Using the TMI accident as a reference, the demonstration system shows how the LPS technology can be employed to handle some of the operational deficiencies encountered during the accident. It illustrates the sequence of events including the manual actions, and shows places where the LPS would have intervened to prevent the accident. The purpose of this report is to evaluate this demonstration system both in terms of its applicability to the nuclear industry, and the technology used. Specific recommendations for consideration by EPRI are made. 8 refs., 9 figs

  11. Evaluation of E/EV/SE aptitude to very long duration. Final report of working groups

    International Nuclear Information System (INIS)

    A joint COGEMA/CEA action aims at evaluating the conditions allowing the extension beyond 50 years of the exploitation of the E/EV/SE vitrified wastes storage facility of the UP3 factory of La Hague (France). The approach considered consists in analysing the technical and administrative aspects of the facility in order to determine the changes to be implemented for its qualification as very long storage facility. Three target characteristics have been identified as priorities for this analysis: safety, civil engineering, and cooling ventilation of wells, and thus three working groups have been created. According to works carried out, facilities like the E/EV/SE one are designed in such a way that their durability can reach the century scale: the robustness of the cooling process, the passiveness of most equipments and the limitation of components functions are the main strong points. Service life limitations come mainly from the thermal evolution of waste packages and the aging of components under the climate conditions: risk of atmospheric corrosion of the bottom part of wells under the effect of water condensation, and risk of corrosion of concrete reinforcements. Suggestions of improvement of the quantification and understanding of phenomena influencing the lifetime limitation are made, and some possible technical solutions are proposed. (J.S.)

    1993-09-01

    The New York City Department of Sanitation is developing a comprehensive landfill leachate management plan for the Fresh Kills landfill, located on the western shore of Staten Island, New York. The 3000-acre facility, owned and operated by the City of New York, has been developed into four distinct mounds that correspond to areas designated as Sections 1/9, 2/8, 3/4 and 6/7. In developing a comprehensive leachate management plan, the estimating leachate flow rates is important in designing appropriate treatment alternatives to reduce the offsite migration that pollutes both surface water and groundwater resources.Estimating the leachate flow rates from Sections 1/9 and 6/7 was given priority using an available model, hydrologic evaluation of landfill performance (HELP), and a new model, flow investigation for landfill leachate (FILL). The field-scale analysis for leachate flow included data collection of the leachate mound-level from piezometers and monitoring wells installed on-site, for six months period. From the leachate mound-head contours and flow-gradients, Leachate flow rates were computed using Darcy`s Law.

  13. Grand Junction Projects Office Remedial Action Project Building 2 public dose evaluation. Final report

    International Nuclear Information System (INIS)

    Building 2 on the U.S. Department of Energy (DOE) Grand Junction Projects Office (GJPO) site, which is operated by Rust Geotech, is part of the GJPO Remedial Action Program. This report describes measurements and modeling efforts to evaluate the radiation dose to members of the public who might someday occupy or tear down Building 2. The assessment of future doses to those occupying or demolishing Building 2 is based on assumptions about future uses of the building, measured data when available, and predictive modeling when necessary. Future use of the building is likely to be as an office facility. The DOE sponsored program, RESRAD-BUILD, Version. 1.5 was chosen for the modeling tool. Releasing the building for unrestricted use instead of demolishing it now could save a substantial amount of money compared with the baseline cost estimate because the site telecommunications system, housed in Building 2, would not be disabled and replaced. The information developed in this analysis may be used as part of an as low as reasonably achievable (ALARA) cost/benefit determination regarding disposition of Building 2

  14. Evaluating United States and world consumption of neodymium, dysprosium, terbium, and praseodymium in final products

    -term (2015) and mid-term (2020) scenarios could be between: 1,984 to 6,475 tons (2015) and 3,487 to 13,763 tons (2020) of neodymium; 331 to 864 tons (2015) and 587 to 1,834 tons (2020) of dysprosium; 123 to 325 tons (2015) and 219 to 687 tons (2020) of terbium; finally, zero to 871 tons (2015) and zero to 1,493 tons (2020) of praseodymium. Hybrid vehicle sales in non-U.S. countries could account for a large portion of magnetic rare earth consumption. Wind turbine and related rare earth consumption growth will also be driven by non-U.S. countries, especially developing nations like China. Despite wind turbines using bigger magnets, the sheer volume of hybrids sold and non-U.S. consumers could account for most future consumption of permanent magnets and their rare earths.

  15. The evaluation of a 4000-home geothermal heat pump retrofit at Fort Polk, Louisiana: Final Report

    Hughes, P.J.; Shonder, J.A.

    1998-03-01

    This report documents an independent evaluation of an energy retrofit of 4,003 family housing units at Fort Polk, Louisiana, under an energy savings performance contract (ESPC). Replacement of the heating, cooling, and water heating systems in these housing units with geothermal heat pumps (GHPs) anchored the retrofit; low-flow shower heads and compact fluorescent lighting were also installed, as well as attic insulation where needed. Statistically valid findings indicate that the project will save 25.8 million kWh, or 32.5% of the pre-retrofit whole-community electrical consumption, and 100% of the whole-community natural gas previously used for space conditioning and water heating (260,000 therms) in a typical meteorological year. At the end-use level, the GHPs were found to save about 42% of the pre-retrofit electrical consumption for heating, cooling, and water heating in housing units that were all-electric in the pre-retrofit period. This report also demonstrates an improved method of predicting energy savings. Using an engineering model calibrated to pre-retrofit energy use data collected in the field, the method predicted actual energy savings on one of the electric feeders at Fort Polk with a very high degree of accuracy. The accuracy of this model was in turn dependent on data-calibrated models of the geothermal heat pump and ground heat exchanger that are described in this report. In addition this report documents the status of vertical borehole ground heat exchanger (BHEx) design methods at the time this project was designed, and demonstrates methods of using data collected from operating GHP systems to benchmark BHEx design methods against a detailed engineering model calibrated to date. The authors also discuss the ESPC`s structure and implementation and how the experience gained here can contribute to the success of future ESPCs.

  16. Program to monitor and evaluate a passive solar greenhouse/aquaculture system. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1982-01-01

    A temperature monitoring program of Amity's solar greenhouse demonstrated that air, soil, and water temperatures can be maintained at optimal levels without supplemental heat. A foil reflector placed in front of the greenhouse glazing at an angle of between 0 and 5/sup 0/ above horizontal enhanced direct light entering the greenhouse by as much as 22%. Aquaculture in the water heat storage of a solar greenhouse has been a success. Fish reached harvest size in about seven months. The two species that were received the best by the public were African perch (Tilapia mossambica) and channel catfish (Ictalurus punctatus). Although carp (Cyprinus carpio) were the fastest growers they were not well received by the public. Linking hydroponics to greenhouse aquaculture shows a lot of promise. Different support medias were examined and tomatoes and European cucumbers were raised successfully. A savonius windmill was successfully linked to an aquaculture aeration system but because of the wind pattern in the Willamette valley the windmill system did not provide air in the evening when it was needed most. Alternate designs are discussed. Locally grown fish diets were evaluated for their ability to promote fish growth. Diets such as water hyacinth, duckweed, earthworms, beans, and comfrey were raised on the Amity site, pelleted with a hand grinder and solar dried. Duckweed and earthworms appear to hold promise for a nutritous, easy to grow and pelletize, food source. Amity's solar greenhouse, three coldframe designs and a PVC tunnel cloche were compared in a vegetable growing trial. Most impressive was the cloche design because it provided adequate protection, was inexpensive and very easy to build.

  17. Evaluation of selected drive components for a flywheel-powered commuter vehicle, Phase I. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1977-06-30

    The Phase I tasks of a project for the development of an energy storing flywheel powerplant for a short-range commuter vehicle were directed towards evaluating and characterizing specific technologies associated with the flywheel propulsion system that were considered to be critical to the successful development of the proposed commuter car. The vehicle flywheel would be designed to operate between 20,000 and 41,000 rpm, storing a total of 16 kw-hrs at the maximum speed of 41,000 rpm. Vertical spin axes were selected so that normal vehicle cornering would not induce gyroscopic forces on the flywheel bearings. Two rotors would turn in opposite directions so that any gyroscopic forces produced by vehicle pitch or roll motions would be balanced within the flywheel assembly and not reflected to the chassis. Each rotor would be assembled from six identical modules stacked on a common shaft, each module being of multi-rim construction. In Phase I, the rotor testing was limited to the outer (most highly stressed) rims from a single module. The bearings and seals were tested under load conditions simulating those expected from a complete six module rotor. The flywheel system failed to achieve target speed and exhibited whip-like instability of the shaft/hub/spoke combination. The bearings and lubricant performed satisfactorily. The ferrofluidic centrifugal seals lacked the ability to withstand adequate pressure differentials. It is recommended that the project concentrate on the development of smaller, composite material flywheels suitable for use in hybrid vehicles. (LCL)

    2015-11-01

    Oak Ridge National Laboratory (ORNL) performed a detailed technical review of the 2015 Electrabel (EBL) Safety Cases prepared for the Belgium reactor pressure vessels (RPVs) at Doel 3 and Tihange 2 (D3/T2). The Federal Agency for Nuclear Control (FANC) in Belgium commissioned ORNL to provide a thorough assessment of the existing safety margins against cracking of the RPVs due to the presence of almost laminar flaws found in each RPV. Initial efforts focused on surveying relevant literature that provided necessary background knowledge on the issues related to the quasilaminar flaws observed in D3/T2 reactors. Next, ORNL proceeded to develop an independent quantitative assessment of the entire flaw population in the two Belgian reactors according to the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code, Section XI, Appendix G, Fracture Toughness Criteria for Protection Against Failure, New York (1992 and 2004). That screening assessment of all EBL-characterized flaws in D3/T2 used ORNL tools, methodologies, and the ASME Code Case N-848, Alternative Characterization Rules for QuasiLaminar Flaws . Results and conclusions from the ORNL flaw acceptance assessments of D3/T2 were compared with those from the 2015 EBL Safety Cases. Specific findings of the ORNL evaluation of that part of the EBL structural integrity assessment focusing on stability of the flaw population subjected to primary design transients include the following: ORNL s analysis results were similar to those of EBL in that very few characterized flaws were found not compliant with the ASME (1992) acceptance criterion. ORNL s application of the more recent ASME Section XI (2004) produced only four noncompliant flaws, all due to LOCAs. The finding of a greater number of non-compliant flaws in the EBL screening assessment is due principally to a significantly more restrictive (conservative) criterion for flaw size acceptance used by EBL.

    Addition of phenol recovery to the wastewater treatment scheme in the Baseline Design for the SRC-I Demonstration Plant was evaluated as a major post-Baseline effort. Phenol recovery affects many downstream processes, but this study was designed to assess primarily its effects on biooxidation and subsequent tertiary treatment. Two parallel treatment schemes were set up, one to treat dephenolated wastewaters and the other for processed nondephenolated wastewaters, a simulation of the Baseline Design. The study focused on comparisons of five areas: effluent quality; system stability; the need for continuous, high-dose powdered activated carbon (PAC) augmentation to the bioreactor; minimum bioreactor hydraulic residence time (HRT); and tertiary treatment requirements. The results show that phenol recovery improves the quality of the bioreactor effluent in terms of residual organics and color. With phenol recovery, PAC augmentation is not required; without phenol recovery, PAC is needed to produce a comparable effluent. Dephenolization also enhances the stability of biooxidation, and reduces the minimum HRT required. With tertiary treatment, both schemes can meet the effluent concentrations published in the SRC-I Final Envivornmental Impact Statement, as well as the anticipated effluent limits. However, phenol recovery does provide a wider safety margin and could eliminate the need for some of the tertiary treatment steps. Based solely on the technical merits observed in this study, phenol recovery is recommended. The final selection should, however, also consider economic tradeoffs and results of other studies such as toxicology testing of the effluents. 34 references, 30 figures and 26 tables.

  3. On-road, in-use gaseous emission measurements by remote sensing of school buses equipped with diesel oxidation catalysts and diesel particulate filters.

    Burgard, Daniel A; Provinsal, Melissa N

    2009-12-01

    A remote sensing device was used to obtain on-road and in-use gaseous emission measurements from three fleets of schools buses at two locations in Washington State. This paper reports each fleet's carbon monoxide (CO), hydrocarbon (HC), nitric oxide (NO), and nitrogen dioxide (NO2) mean data. The fleets represent current emission retrofit technologies, such as diesel particulate filters and diesel oxidation catalysts, and a control fleet. This study shows that CO and HC emissions decrease with the use of either retrofit technology when compared with control buses of the same initial emission standards. The CO and HC emission reductions are consistent with published U.S. Environmental Protection Agency verified values. The total oxides of nitrogen (NOx), NO, and the NO2/NOx ratio all increase with each retrofit technology when compared with control buses. As was expected, the diesel particulate filters emitted significantly higher levels of NO2 than the control fleet because of the intentional conversion of NO to NO2 by these systems. Most prior research suggests that NOx emissions are unaffected by the retrofits; however, these previous studies have not included measurements from retrofit devices on-road and after nearly 5 yr of use. Two 2006 model-year buses were also measured. These vehicles did not have retrofit devices but were built to more stringent new engine standards. Reductions in HCs and NOx were observed for these 2006 vehicles in comparison to other non-retrofit earlier model-year vehicles. PMID:20066912

  5. Final safety evaluation report related to the certification of the Advanced Boiling Water Reactor design. Supplement 1

    International Nuclear Information System (INIS)

    This report supplements the final safety evaluation report (FSER) for the US Advanced Boiling Water Reactor (ABWR) standard design. The FSER was issued by the US Nuclear Regulatory Commission (NRC) staff as NUREG-1503 in July 1994 to document the NRC staff's review of the US ABWR design. The US ABWR design was submitted by GE Nuclear Energy (GE) in accordance with the procedures of Subpart B to Part 52 of Title 10 of the Code of Federal Regulations. This supplement documents the NRC staff's review of the changes to the US ABWR design documentation since the issuance of the FSER. GE made these changes primarily as a result of first-of-a-kind-engineering (FOAKE) and as a result of the design certification rulemaking for the ABWR design. On the basis of its evaluations, the NRC staff concludes that the confirmatory issues in NUREG-1503 are resolved, that the changes to the ABWR design documentation are acceptable, and that GE's application for design certification meets the requirements of Subpart B to 10 CFR Part 52 that are applicable and technically relevant to the US ABWR design

  6. Integrated plant safety assessment. Systematic evaluation program, Big Rock Point Plant (Docket No. 50-155). Final report

    International Nuclear Information System (INIS)

    The Systematic Evaluation Program was initiated in February 1977 by the U.S. Nuclear Regulatory Commission to review the designs of older operating nuclear reactor plants to reconfirm and document their safety. The review provides (1) an assessment of how these plants compare with current licensing safety requirements relating to selected issues, (2) a basis for deciding how these differences should be resolved in an integrated plant review, and (3) a documented evaluation of plant safety when the supplement to the Final Integrated Plant Safety Assessment Report has been issued. This report documents the review of the Big Rock Point Plant, which is one of ten plants reviewed under Phase II of this program. This report indicates how 137 topics selected for review under Phase I of the program were addressed. It also addresses a majority of the pending licensing actions for Big Rock Point, which include TMI Action Plan requirements and implementation criteria for resolved generic issues. Equipment and procedural changes have been identified as a result of the review

    2015-11-01

    A total of 13 diesel buses and 12 diesel trucks in Macao were tested using portable emission measurement systems (PEMS) including a SEMTECH-DS for gaseous emissions and a SEMTECH-PPMD for PM2.5. The average emission rates of gaseous pollutants and CO2 are developed with the operating mode defined by the instantaneous vehicle specific power (VSP) and vehicle speed. Both distance-based and fuel mass-based emission factors for gaseous pollutants (e.g., CO, THC and NOX) are further estimated under typical driving conditions. The average distance-based NOX emission of heavy-duty buses (HDBs) is higher than 13 g km-1. Considering the unfavorable conditions for selective reductions catalyst (SCR) systems, such as low-speed driving conditions, more effective technology options (e.g., dedicated natural gas buses and electric buses) should be considered by policy makers in Macao. We identified strong effects of the vehicle size, engine displacement and driving conditions on real-world CO2 emission factors and fuel consumption for diesel vehicles. Therefore, detailed profiles regarding vehicle specifications can reduce the uncertainty in their fleet-average on-road fuel consumption. In addition, strong correlations between relative emission factors and driving conditions indicated by the average speed of generated micro-trips are identified based on a micro-trip method. For example, distance-based emission factors of HDBs will increase by 39% for CO, 29% for THC, 43% for NOX and 26% for CO2 when the average speed decreases from 30 km h-1 to 20 km h-1. The mitigation of on-road emissions from diesel buses and trucks by improving traffic conditions through effective traffic and economic management measures is therefore required. This study demonstrates the important role of PEMS in understanding vehicle emissions and mitigation strategies from science to policy perspectives.

The purpose of this study was to examine the feasibility of the RCGP proposal to implement a QIP in the final year of training. An educational intervention was designed and delivered to a group of GP trainees six months before the end of their training. This comprised facilitated small group work, web resources and guiding paperwork to structure meetings between the trainee and trainer to monitor and support the development of the project. The projects were marked and presented to a panel. The evaluation included a questionnaire to trainees, interviews with trainees and trainers and a focus group with facilitators and markers. The results suggest that the educational intervention was feasible and acceptable to GP trainees, trainers and practices. It resulted in an increase in confidence of GP trainees in understanding quality improvement methodologies and in undertaking QIP in general practices. In particularly, GP trainees highly valued the experience and leadership skills gained through engagement in change management which was viewed as advantageous for their future careers. Facilitated small group meetings and support from others in the practice were most useful resources supporting the development of QIP. PMID:26947015

    This report supplements the final safety evaluation report (FSER) for the System 80+ standard design. The FSER was issued by the US Nuclear Regulatory Commission (NRC) staff as NUREG-1462 in August 1994 to document the NRC staff`s review of the System 80+ design. The System 80+ design was submitted by Asea Brown Boveri-Combustion Engineering (ABB-CE), in accordance with the procedures of Subpart B to Part 52 of Title 10 of the Code of Federal Regulations. This supplement documents the NRC staff`s review of the changes to the System 80+ design documentation since the issuance of the FSER. ABB-CE made these changes as a result of its review of the System 80+ design details. The NRC staff concludes that the changes to the System 80+ design documentation are acceptable, and that ABB-CE`s application for design certification meets the requirements of Subpart B to 10 CFR Part 52 that are applicable and technically relevant to the System 80+ design.

  12. Review and evaluation of immobilized algae systems for the production of fuels from microalgae. Final subcontract report

    Energy Technology Data Exchange (ETDEWEB)

    1985-11-01

    The purpose of this paper is to review and evaluate the use of immobilized algae systems. It was the finding that commercial immobilized algae systems are not in operation at this time but, with research, could certainly become so. The use of immobilized algae will depend on, as in all commercial systems, the economic value of the product. This paper reviews the technical feasibility of immobilization as it applies to algae. Finally, the economics of possible immobilized algal systems that would produce liquid fuels were investigated. It was calculated that an immobilized system would have 8.5 times the capital costs of a conventional microalgae culture system. Operational costs would be about equal, although there would be substantial savings of water with the immobilized system. A major problem with immobilizing algae is the fact that sunlight drives the system. At present, an immobilized algal system to mass produce lipids for use as a liquid fuel does not appear to be economically feasible. The major drawback is developing a low-cost system that obtains the same amount of solar energy as provided to a shallow 3 square mile pond while increasing the culture density by an order of magnitude. R and D to increase light availability and to develop low cost transparent tanks could increase the competitiveness of immobilized algal systems. 44 refs., 2 figs., 7 tabs.

  13. Demonstration, testing, ampersand evaluation of in situ heating of soil. Draft final report, Volume II: Appendices A to E

    International Nuclear Information System (INIS)

    This document is a draft final report for US DOE contract entitled, open-quotes Demonstration Testing and Evaluation of In Situ Soil Heating,close quotes Contract No. DE-AC05-93OR22160, IITRI Project No. C06787. This report is presented in two volumes. Volume I contains the technical report This document is Volume II, containing appendices with background information and data. In this project approximately 300 cu. yd. of clayey soil containing a low concentration plume of volatile organic chemicals was heated in situ by the application of electrical energy. It was shown that as a result of heating the effective permeability of soil to air flow was increased such that in situ soil vapor extraction could be performed. The initial permeability of soil was so low that the soil gas flow rate was immeasurably small even at high vacuum levels. When scaled up, this process can be used for the environmental clean up and restoration of DOE sites contaminated with VOCs and other organic chemicals boiling up to 120 degrees to 130 degrees C in the vadose zone. Although it may applied to many types of soil formations, it is particularly attractive for low permeability clayey soil where conventional in situ venting techniques are limited by low air flow

    This article presents some miscellaneous data from two low-slope and two steep-slope experimental roofs. The low-slope roofs were designed to compare the performance of various roof coatings exposed to natural weatherization. The steep-slope roofs contained different combinations of phase change material, rigid insulation, low emittance surface and above-sheathing ventilation, with standing-seam metal panels on top. The steep-slope roofs were constructed on a series of adjacent attics separated at the gables using thick foam insulation. This article describes phase three (3) of a study that began in 2009 to evaluate the energy benefits of a sustainable re-roofing technology utilizing standing-seam metal roofing panels combined with energy efficient features like above-sheathing-ventilation (ASV), phase change material (PCM) and rigid insulation board. The data from phases 1 and 2 have been previously published and reported [Kosny et al., 2011; Biswas et al., 2011; Biswas and Childs, 2012; Kosny et al., 2012]. Based on previous data analyses and discussions within the research group, additional test roofs were installed in May 2012, to test new configurations and further investigate different components of the dynamic insulation systems. Some experimental data from phase 3 testing from May 2012 to December 2013 and some EnergyPlus modeling results have been reported in volumes 1 and 3, respectively, of the final report [Biswas et al., 2014; Biswas and Bhandari, 2014].

  18. Evaluation and performance based mix design of rubber modified mixtures: Laboratory evaluation of asphalt concrete mixtures using waste tires. Final report

    Energy Technology Data Exchange (ETDEWEB)

    Goulias, D.G.; Ali, A.H.M.

    1997-02-01

    New Jersey Department of Transportation has been investigating the use of rubber modified materials over the last few years with the design and use of dense and gap graded mixtures, and in some cases the incorporation of RAP materials, in selected projects. While the short term field performance of these materials is satisfactory, their long term performance is unknown. These mixtures were designed with the traditional Marshall mixture design method, and thus is was not considered design criteria related to mixture behavior and performance into mixture selection. The main objective of this study is the development of a mixture design methodology for rubber modified materials that considers mixture behavior and performance. In order to achieve this objective researchers conducted a laboratory investigation which was able to evaluate mixture properties that can be related to mixture performance, (in terms of rutting, low temperature cracking, and fatigue), and simulating the actual field loading conditions that the material is being exposed to. The possibility of coupling the traditional Marshall mix design method with parameters related to mixture behavior and performance was investigated since this technique has been used over the years by the agency, and the necessary testing apparatus is available to both the agency and material laboratories. The SHRP SUPERPAVE mix design methodology was reviewed and considered in this study for the development of an integrated performance based design procedure. However, its applicability and use on routine bases was not considered at this time since it requires specific equipment with ongoing evaluation for its repeatability and precision. Finally, for the conduct of this investigation materials and mixtures used by NJDOT in rubber modified paving projects were used.

  19. Evaluation of dose due to the liberation of the radioactive content present in systems of final disposal of radioactive residues

    International Nuclear Information System (INIS)

    The disposal systems of radioactive residuals well-known as repositories near to the surface, are used to dispose residuals that can contain high concentrations of radionuclides of period of short semi disintegration, which they would decay at levels radiologically insignificant in some few decades or in some centuries: and acceptably low concentrations of radionuclides of period of long semi disintegration. The dose that would receive the critic group due to these systems it could be increased by cause of discreet events that affect the foreseen retard time, or by the gradual degradation of the barriers. To this last case it contributes the presence of water, because it implies leaching and dissolution that can give place to radionuclide concentrations in the underground water greater to the prospective ones. The dosimetric evaluation is important because it offers useful objective information to decide if a given repository is adjusted to the purposes of its design and it fulfills the regulatory requirements. In this work a simplified evaluation of the dose that would receive the critic group due to the liberation of contained radionuclides in a hypothetical system of final disposition of radioactive residuals is presented. For it, they are considered representative values of the usually contained activities in this type of systems and they are carried out some approaches of the source term. The study is developed in two stages. In the first one, by means of the Radionuclide pollutant scattering pattern in phreatic aquifers (DRAF) it is considered the scattering of the pollutants in the phreatic aquifer, until the discharge point in the course of the nearest surface water. This model, developed originally in the regulatory branch of the National Commission of Argentine Atomic Energy (CNEA); it solves the transport equation of solutes in porous means in three dimensions, by the finite differences method having in account the soil retention and the radioactive

  1. Evaluation of interim and final waste forms for the newly generated liquid low-level waste flowsheet

    International Nuclear Information System (INIS)

    The purpose of this review is to evaluate the final forms that have been proposed for radioactive-containing solid wastes and to determine their application to the solid wastes that will result from the treatment of newly generated liquid low-level waste (NGLLLW) and Melton Valley Storage Tank (MVST) supernate at the Oak Ridge National Laboratory (ORNL). Since cesium and strontium are the predominant radionuclides in NGLLLW and MVST supernate, this review is focused on the stabilization and solidification of solid wastes containing these radionuclides in cement, glass, and polymeric materials-the principal waste forms that have been tested with these types of wastes. Several studies have shown that both cesium and strontium are leached by distilled water from solidified cement, although the leachabilities of cesium are generally higher than those of strontium under similar conditions. The situation is exacerbated by the presence of sulfates in the solution, as manifested by cracking of the grout. Additives such as bentonite, blast-furnace slag, fly ash, montmorillonite, pottery clay, silica, and zeolites generally decrease the cesium and strontium release rates. Longer cement curing times (>28 d) and high ionic strengths of the leachates, such as those that occur in seawater, also decrease the leach rates of these radionuclides. Lower cesium leach rates are observed from vitrified wastes than from grout waste forms. However, significant quantities of cesium are volatilized due to the elevated temperatures required to vitrify the waste. Hence, vitrification will generally require the use of cleanup systems for the off-gases to prevent their release into the atmosphere

  3. Fast Charging Battery Buses for the Electrification of Urban Public Transport—A Feasibility Study Focusing on Charging Infrastructure and Energy Storage Requirements

    Directory of Open Access Journals (Sweden)

    Matthias Rogge

    2015-05-01

    Full Text Available The electrification of public transport bus networks can be carried out utilizing different technological solutions, like trolley, battery or fuel cell buses. The purpose of this paper is to analyze how and to what extent existing bus networks can be electrified with fast charging battery buses. The so called opportunity chargers use mainly the regular dwell time at the stops to charge their batteries. This results in a strong linkage between the vehicle scheduling and the infrastructure planning. The analysis is based on real-world data of the bus network in Muenster, a mid-sized city in Germany. The outcomes underline the necessity to focus on entire vehicle schedules instead on individual trips. The tradeoff between required battery capacity and charging power is explained in detail. Furthermore, the impact on the electricity grid is discussed based on the load profiles of a selected charging station and a combined load profile of the entire network.

  4. At what extent the benefits of introducing alternative light-duty vehicles offset those of increasing the buses average occupancy?

    International Nuclear Information System (INIS)

    Highlights: • Characterization of fuel consumption, emissions and daily distance, of road fleet by probability distribution functions. • The co-benefit of congestion level decrease due to mode-shifting from LDV to bus is explored. • A potential decrease in NOx + PM of 23% is foreseen, by 50% LDV replacement or mode-shifting (bus occupancy 40–80%). • A decrease of CO2 is foreseen as being 20%, by 50% LDV replacement or mode-shifting (bus occupancy 30–60%). • Electricity mix relaying on renewables will increase the window were the energy and CO2 benefits match to 35%. - Abstract: This paper quantifies the energy and emissions benefits of introducing electric drive vehicles (pure electric, plug-in hybrid and fuel cell) on a conventional light-duty fleet (LDV) versus promoting the intensification of the public transportation use by means of mode-shifting and increased average bus occupancy. The impact is assessed in terms of energy, local pollutants, HC, CO, NOx, PM, and global emissions of CO2. The specific fleet of Portugal is used as case study. This fleet has roughly 6 million LDV (30% diesel, 70% gasoline) and 15,000 buses, with a mobility indicator of 106 thousand million passengerxkm (pkm). Probability density functions for energy consumption and emissions are derived for conventional, electric drive vehicles, and buses, avoiding considering one representative vehicle of each. Scenarios of 30–50% conventional fleet replacement is compared against scenarios of bus occupancy increase from 20% to 80%. The increased bus occupancy is made by mode-shifting from conventional LDV vehicles keeping the mobility pkm and bus supply. The co-benefit of congestion level decrease due to mode-shifting is explored. The effect of different electricity mixes is also analyzed. The methodology used allowed obtaining likelihood functions for energy consumption and emissions for each scenario and offset areas where the benefits match. The use of the methodology for

    International Nuclear Information System (INIS)

    TASK 45 FIELD DEPLOYMENT EVALUATION OF THE FREEZE-THAW/ EVAPORATION (FTE ) PROCESS TO TREAT OIL AND GAS PRODUCED WATERS coupling evaporation with freezing. This offers operators a year- round method for treating produced water. Treating water with the FTE process reduces the volume of water to be disposed of as well as purifying the water to a level acceptable for watering livestock and agricultural lands. This process is currently used at two evaporation facilities, one in the San Juan Basin in New Mexico and one in the Green River Basin in Wyoming. the freezing point below that of pure water. When such a solution is cooled below 32EF, relatively pure ice crystals form, along with an unfrozen brine solution that contains elevated concentrations of salts. Because of the brine's high concentration of these constituents, its density is greater than that of the ice, and the purified ice and brine are easily separated. Coupling the natural processes of freezing and evaporation makes the FTE process a more cost- effective and efficient method for the treatment and disposal of produced water and allows for year-round operation of an FTE facility. drops below 32 F, produced water is automatically pumped from a holding pond and sprayed onto a freezing pad. The freezing pad consists of an elevated framework of piping with regularly placed, upright, extendable spray heads similar to those used to irrigate lawns. As the spray freezes, an ice pile forms over the elevated framework of pipes, and the brine, with an elevated constituent concentration, drains from the ice pile. The high-salinity brine, identified by its high electrical conductivity, is separated using automatic valves and pumped to a pond where it can subsequently be disposed of by conventional methods. As the ice pile increases in height, the sprayers are extended. When the ice on the freezing pad melts, the relatively pure water is pumped from the freezing pad and discharged or stored for later use . No new

  6. Technological capability assessment of suppliers to support product development: case study on a buses and coaches manufacturer

    2013-05-01

    Full Text Available Supply chain management has become a critical issue in the global collaboration scenario. Suppliers are not expected to provide just commodities or pre-defined components, but also collaborative engineering design solutions within the product development cycle. Thus, the selection criteria for defining supply partner go beyond the production and logistic capabilities, but must also include technical and engineering competence. This, in some sense, can be considered a common scenario of big companies, but is still challenging when dealing with SME´s. This work discusses how SME´s can be included in a supply chains taking in consideration a set of parameters to assess their technical competence related to product development collaboration. A set of eight parameters has been proposed to assess the engineering team competence, physical and technological structure and further legal responsibility. For each parameter values and weights were defined also. The assessment was applied to three companies that are suppliers of a buses and coaches manufacturer from Rio Grande do Sul, Brazil. The results show that even when dealing with objective parameters, the suppliers and costumer can have different perceptions about same issues.

    Traffic jam and air pollution by automobiles are currently getting severe in the Mexico Metropolitan Area. Trolley buses were introduced for improving the environment more than ten years ago. Vehicles become too old for use, and their energy efficiency is low. In this project, 200 highly energy-efficient trolley buses are introduced to replace old inefficient trolley buses, which results in the improved traffic convenience in the City and enhanced energy efficiency. The new energy-efficient trolley buses are made of energy-efficient control VVVF inverters produced and exported by MELCO (Mitsubishi Electric Corporation), energy-efficient motors by MELMEX (Mitsubishi Electric Corporation, Mexico), and bodies by MASA which is a major manufacturer of bus bodies. The objective of this research is to analyze the background of introduction of new energy-efficient trolley buses and the effects of the present project.

  16. R&D for computational cognitive and social models : foundations for model evaluation through verification and validation (final LDRD report).

    Energy Technology Data Exchange (ETDEWEB)

    Slepoy, Alexander; Mitchell, Scott A.; Backus, George A.; McNamara, Laura A.; Trucano, Timothy Guy

    2008-09-01

    Sandia National Laboratories is investing in projects that aim to develop computational modeling and simulation applications that explore human cognitive and social phenomena. While some of these modeling and simulation projects are explicitly research oriented, others are intended to support or provide insight for people involved in high consequence decision-making. This raises the issue of how to evaluate computational modeling and simulation applications in both research and applied settings where human behavior is the focus of the model: when is a simulation 'good enough' for the goals its designers want to achieve? In this report, we discuss two years' worth of review and assessment of the ASC program's approach to computational model verification and validation, uncertainty quantification, and decision making. We present a framework that extends the principles of the ASC approach into the area of computational social and cognitive modeling and simulation. In doing so, we argue that the potential for evaluation is a function of how the modeling and simulation software will be used in a particular setting. In making this argument, we move from strict, engineering and physics oriented approaches to V&V to a broader project of model evaluation, which asserts that the systematic, rigorous, and transparent accumulation of evidence about a model's performance under conditions of uncertainty is a reasonable and necessary goal for model evaluation, regardless of discipline. How to achieve the accumulation of evidence in areas outside physics and engineering is a significant research challenge, but one that requires addressing as modeling and simulation tools move out of research laboratories and into the hands of decision makers. This report provides an assessment of our thinking on ASC Verification and Validation, and argues for further extending V&V research in the physical and engineering sciences toward a broader program of model

  20. Screening study for evaluation of the potential for system 80+ to consume excess plutonium - Volume 1. Final report

    Energy Technology Data Exchange (ETDEWEB)

    1994-04-30

    As part of the U.S. effort to evaluate technologies offering solutions for the safe disposal or utilization of surplus nuclear materials, the fiscal year 1993 Energy and Water Appropriations legislation provided the Department of Energy (DOE) the necessary funds to conduct multi-phased studies to determine the technical feasibility of using reactor technologies for the triple mission of burning weapons grade plutonium, producing tritium for the existing smaller weapons stockpile, and generating commercial electricity. DOE limited the studies to five advanced reactor designs. Among the technologies selected is the ABB-Combustion Engineering (ABB-CE) System 80+. The DOE study, currently in Phase ID, is proceeding with a more detailed evaluation of the design`s capability for plutonium disposition.

  1. Preliminary evaluation of a method using an FID (flame ionization detector) for measurement of methanol in auto emissions. Final report

    International Nuclear Information System (INIS)

    This report evaluates a simplified technique for estimating methanol emission rates in auto exhaust. The technique, referred to as the FID Bubbled Method or FBM, is based in principle on the fact that, while hydrocarbons are not readily absorbed in water, methanol is. Hence, by using a heated flame ionization detector to measure the organic mass in samples before and after bubbling them in water, the quantity of methanol originally present can be estimated by taking the difference between the measurements. Evaluation of the method was done by comparing methanol measurements using the FBM with measurements made using an established reference method. Results showed poor to fair agreement between the two methods. The FBM appeared better at estimating methanol emission rates from evaporative tests than from exhaust tests and also exhibited better accuracy for samples containing higher levels of methanol

  2. Evaluation of the appropriate land-surface resolution for climate models. Final report, August 1, 1992--July 31, 1995

    1998-07-17

    The land surface interacts strongly with the atmosphere at all spatial and temporal scales. Therefore, land-surface processes must be represented as accurately as possible in climate models. The investigation conducted under this project was aimed at answering two major questions related to land-surface processes: (1) What are the land-surface characteristics and processes that need to be represented in a climate model? (2) How does one average, in a nonlinear form, land-surface energy fluxes over heterogeneous domain at the scale that is not represented explicitly in the model? Correspondingly, two major tasks were conducted: (1) an evaluation of the relative importance of the various land-surface characteristics based on their impact on the redistribution of energy into turbulent sensible heat flux and turbulent latent heat flux at the ground surface; and (2) an evaluation of the impact of the heterogeneity of these characteristics on land-surface energy and mass fluxes into the atmosphere.

    The project was aimed at demonstrating that the geothermometric predictions can be improved through the application of multi-element reaction path modeling that accounts for lithologic and tectonic settings, while also accounting for biological influences on geochemical temperature indicators. The limited utilization of chemical signatures by individual traditional geothermometer in the development of reservoir temperature estimates may have been constraining their reliability for evaluation of potential geothermal resources. This project, however, was intended to build a geothermometry tool which can integrate multi-component reaction path modeling with process-optimization capability that can be applied to dilute, low-temperature water samples to consistently predict reservoir temperature within ±30 °C. The project was also intended to evaluate the extent to which microbiological processes can modulate the geochemical signals in some thermal waters and influence the geothermometric predictions.

    A selected group of reported tests of chemical additives in actual geothermal fluids are reviewed and evaluated to summarize the status of chemical scale-control testing and identify information and testing needs. The task distinguishes between scale control in the cooling system of a flash plant and elsewhere in the utilization system due to the essentially different operating environments involved. Additives for non-cooling geothermal fluids are discussed by scale type: silica, carbonate, and sulfide.

  10. Simulation studies to evaluate the effect of fracture closure on the performance of fractured reservoirs; Final report

    Energy Technology Data Exchange (ETDEWEB)

    Howrie, I.; Dauben, D.

    1994-03-01

    A three-year research program to evaluate the effect of fracture closure on the recovery of oil and gas from naturally fractured reservoirs has been completed. The overall objectives of the study were to: (1) evaluate the reservoir conditions for which fracture closure is significant, and (2) evaluate innovative fluid injection techniques capable of maintaining pressure within the reservoir. The evaluations of reservoir performance were made by a modern dual porosity simulator, TETRAD. This simulator treats both porosity and permeability as functions of pore pressure. The Austin Chalk in the Pearsall Field in of South Texas was selected as the prototype fractured reservoir for this work. During the first year, simulations of vertical and horizontal well performance were made assuming that fracture permeability was insensitive to pressure change. Sensitivity runs indicated that the simulator was predicting the effects of critical reservoir parameters in a logical and consistent manner. The results confirmed that horizontal wells could increase both rate of oil recovery and total oil recovery from naturally fractured reservoirs. In the second year, the performance of the same vertical and horizontal wells was reevaluated with fracture permeability treated as a function of reservoir pressure. To investigate sensitivity to in situ stress, differing loading conditions were assumed. Simulated natural depletions confirm that pressure sensitive fractures degrade well performance. The severity of degradation worsens when the initial reservoir pressure approaches the average stress condition of the reservoir, such as occurs in over pressured reservoirs. Simulations with water injection indicate that degradation of permeability can be counteracted when reservoir pressure is maintained and oil recovery can be increased when reservoir properties are favorable.

  11. Compilation and evaluation of fission yield nuclear data. Final report of a co-ordinated research project 1991-1996

    International Nuclear Information System (INIS)

    Fission product yields are required at several stages of the nuclear fuel cycle and are therefore included in all large international data files for reactor calculations and related applications. Such files are maintained and disseminated by the Nuclear Data Section of the IAEA as a member of an international data centres network. Users of these data are from the fields of reactor design and operation, waste management and nuclear materials safeguards, all of which are essential parts of the IAEA programme. In the 1980s, the number of measured fission yields increased so drastically that the manpower available for evaluating them to meet specific user needs was insufficient. To cope with this task, it was concluded in several meetings on fission product nuclear data, some of them convened by the IAEA, that international co-operation was required, and an IAEA co-ordinated research project (CRP) was recommended. This recommendation was endorsed by the International Nuclear Data Committee, an advisory body for the nuclear data programme of the IAEA. As a consequence, the CRP on the Compilation and Evaluation of Fission Yield Nuclear Data was initiated in 1991, after its scope, objectives and tasks had been defined by a preparatory meeting. The different tasks, such as special evaluations and development of improved methods, were distributed among participants. The results of the research work were discussed and approved by all participants in research co-ordination meetings. For a successful development of theoretical and empirical models, experiments had to be recommended and their results to be awaited, which made necessary an extension of the CRP by two years. This TECDOC is the result of a joint effort of all participants in this CRP. The individual sections represent CRP tasks and were prepared by the participants responsible for doing the research, some of which comprise significant new scientific developments. The appendices to this book contain voluminous

  12. Demonstration, testing, and evaluation of in situ heating of soil. Final report, Volume 2, Appendices A to E

    International Nuclear Information System (INIS)

    This is a final report presented in two volumes. Volume I contains the technical report and Volume II contains appendices with background information and data. In this project approximately 300 cubic yards of clayey soil containing a low concentration plume of volatile organic chemicals was heated in situ by the application of electrical energy. It was shown that as a result of heating the effective permeability of soil to air flow was increased such that in situ soil vapor extraction could be performed. The initial permeability of soil was so low that the soil gas flow rate was immeasurably small even at high vacuum levels. It was demonstrated that the mass flow rate of the volatile organic chemicals was enhanced in the recovered soil gas as a result of heating. When scaled up, this process can be used for the environmental clean up and restoration of DOE sites contaminated with VOC's and other organic chemicals. Although it may be applied to many types of soil formations, it is particularly attractive for low permeability clayey soil where conventional in situ venting techniques are limited by air flow

    Final results from a longitudinal investigation of the effectiveness of cognitive-behavioral treatment with sexual offenders are presented. The study was a randomized clinical trial that compared the reoffense rates of offenders treated in an inpatient relapse prevention (RP) program with the rates of offenders in two (untreated) prison control groups. No significant differences were found among the three groups in their rates of sexual or violent reoffending over an 8-year follow-up period. This null result was found for both rapists and child molesters, and was confirmed in analyses using time to reoffense as the outcome and those controlling for static risk differences across the groups. Closer examination of the RP group's performance revealed that individuals who met the program's treatment goals had lower reoffense rates than those who did not. Although our results do not generally support the efficacy of the RP model, they do suggest a number of ways in which this kind of treatment program can be improved. This study also emphasizes the importance of including appropriate control groups in treatment outcome research. Additional controlled investigations are needed to address the many questions that remain about when and how treatment works for sexual offenders. PMID:15757007

  14. Design and Evaluation of a Clock Multiplexing Circuit for the SSRL Booster Accelerator Timing System - Final Paper

    Energy Technology Data Exchange (ETDEWEB)

    Araya, Million

    2015-08-21

    SPEAR3 is a 234 m circular storage ring at SLAC’s synchrotron radiation facility (SSRL) in which a 3 GeV electron beam is stored for user access. Typically the electron beam decays with a time constant of approximately 10hr due to electron lose. In order to replenish the lost electrons, a booster synchrotron is used to accelerate fresh electrons up to 3GeV for injection into SPEAR3. In order to maintain a constant electron beam current of 500mA, the injection process occurs at 5 minute intervals. At these times the booster synchrotron accelerates electrons for injection at a 10Hz rate. A 10Hz 'injection ready' clock pulse train is generated when the booster synchrotron is operating. Between injection intervals-where the booster is not running and hence the 10 Hz ‘injection ready’ signal is not present-a 10Hz clock is derived from the power line supplied by Pacific Gas and Electric (PG&E) to keep track of the injection timing. For this project I constructed a multiplexing circuit to 'switch' between the booster synchrotron 'injection ready' clock signal and PG&E based clock signal. The circuit uses digital IC components and is capable of making glitch-free transitions between the two clocks. This report details construction of a prototype multiplexing circuit including test results and suggests improvement opportunities for the final design.

  17. Evaluation of the UK fusion programme Part A. Final report to the Department of Trade and Industry

    International Nuclear Information System (INIS)

    The UK takes part in thermonuclear fusion R and D through its participation in Euratom, and thereby in the EU's Framework Programme of research and technological development. The UK's work is managed by UKAEA, and is the responsibility of the Nuclear Industries Directorate of the Department of Trade and Industry. The UK's financial support to fusion R and D comprises a portion (ca. 23.5m pounds) of its national contribution to the Framework Programme, a contribution (ca. 6.8m pounds) to the Joint European Torus (JET), and a domestic programme of R and D. The domestic fusion programme receives partial funding from Euratom under the UKAEA/Euratom Contract of Association, and its net cost to the UK is of order 8m pounds. JET is located at the UKAEA site at Culham, Oxfordshire, where the domestic programme is conducted. On 1 January 2000 JET will revert to the ownership of UKAEA, who will operate it under contract while a continuing European JET programme takes place. This report describes the results of an evaluation of the rationale, objectives, organisation and management of the UK Fusion Programme, and the performance achieved by UKAEA. Our evaluation concentrated primarily on the domestic programme, since it is the part of the UK's fusion work over which UKAEA and DTI have most direct control.

    International Nuclear Information System (INIS)

    This safety evaluation report (SER) documents the technical review of the US Advanced Boiling Water Reactor (ABWR) standard design by the US Nuclear Regulatory Commission (NRC) staff. The application for the ABWR design was initially submitted by the General Electric Company, now GE Nuclear Energy (GE), in accordance with the procedures of Appendix O of Part 50 of Title 10 of the code of Federal Regulations (10 CFR Part 50). Later GE requested that its application be considered as an application for design approval and subsequent design certification pursuant to 10 CFR section 52.45. The ABWR is a single-cycle, forced-circulation, boiling water reactor (BWR) with a rated power of 3,926 megawatts thermal (MWt) and a design power of 4,005 MWt. To the extent feasible and appropriate, the staff relied on earlier reviews for those ABWR design features that are substantially the same as those previously considered. Unique features of the ABWR design include internal recirculation pumps, fine-motion control rod drives, microprocessor-based digital logic and control systems, and digital safety systems. On the basis of its evaluation and independent analyses, the NRC staff concludes that, subject to satisfactory resolution of the confirmatory items identified in Section 1.8 of this SER, GE's application for design certification meets the requirements of Subpart B of 10 CFR Part 52 that are applicable and technically relevant to the US ABWR standard design

    The process evaluation reports on the implementation of Orange and Rockland Utilities demand-side bidding program in New York State during 1991 and 1992. The program is implemented by two energy service companies in Orange and rockland`s New York State service territory. The process evaluation methodology included interviews with utility staff (3), energy service company staff (2), and participating (6) and nonparticipating (7) utility customers. The two energy service companies had enrolled 14 customers in the program by summer 1992. One company had achieved 90% of their 2.75 MW bid and the other had achieved less than 90% of their 6.9 MW bid. Critical factors in success were determination of a reasonable bid amount for the market and marketing to the appropriate customers. Customers most interested in the program included those with limited access to capital and medium-sized firms with poor cash flows, particularly schools and hospitals. The findings also show that due to the incentive structure and associated need for substantial customer contributions, lighting measures dominate all installations. Customers, however, were interested in the potential savings and six of the nonparticipants chose to either install measures on their own or enroll in the utility`s rebate program.

    This report describes testing and evaluation performed by the Environmental Laboratory of the U.S. Army Engineer Waterways Experiment Station on sediment from Oakland Inner and Outer Harbor, California. Test protocols from the U.S. Environmental Protection Agency (EPA)/U.S. Army Corps of Engineers' Technical Framework for the Management of Dredged Material were used in the present evaluation to determine the potential for migration of contaminants into effluent, surface runoff, leachate, plants, and animals at an undetermined upland disposal site. One composite sediment each from Oakland Inner Harbor and Oakland Outer Harbor was tested. The composite sample consisted of sediment cores taken from the mud line to 44-ft depth. Both Oakland Harbor sediments had clayey sand textures. Total organic carbon concentrations in sediment from Oakland Inner and Outer Harbors were 3,364 and 6,042 mg/kg, respectively. Based on test results, Oakland Harbor sediments will require management of suspended solids in effluent and surface runoff and a mixing zone of at least 20 to 1 to meet the strictest assumed water quality criteria or standards. Management controls should be considered at the upland site, since plants grew poorly and contained elevated cadmium, lead, and selenium and earthworms accumulated arsenic, cadmium, and nickel.

    The objective of this internal research and development (IRAD)-funded campaign by Aerodyne Research, Inc. was to demonstrate the field-worthiness and assess the performance of a real-time cloud optical depth (COD) sensor (dubbed three-waveband spectrally-agile technique [TWST]) through a side-by-side comparison with proven, ground-based operational sensors currently deployed at the U.S. Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Climate Research Facility Mobile Facility (AMF) site on the Cape Cod National Seashore for the Two-Column Aerosol Project (TCAP). We anticipated direct comparisons with the Aerosol Robotic Network (AERONET; when in cloud mode) and SAS instruments and expected ancillary data from other sensors such as the Total Sky Imager, the Scanning Cloud Radar, and the Microwave Radiometer to facilitate and validate these comparisons. Because the cloud optical depth retrieval algorithms used by AERONET, solar array spectrometer (SAS), and TWST are totally independent, this deployment provided a unique opportunity to evaluate the field performance of TWST. If the effort proves successful, it may qualify TWST for operational service or additional evaluation effort.

  3. Evaluation of potential surface rupture and review of current seismic hazards program at the Los Alamos National Laboratory. Final report

    International Nuclear Information System (INIS)

    This report summarizes the authors review and evaluation of the existing seismic hazards program at Los Alamos National Laboratory (LANL). The report recommends that the original program be augmented with a probabilistic analysis of seismic hazards involving assignment of weighted probabilities of occurrence to all potential sources. This approach yields a more realistic evaluation of the likelihood of large earthquake occurrence particularly in regions where seismic sources may have recurrent intervals of several thousand years or more. The report reviews the locations and geomorphic expressions of identified fault lines along with the known displacements of these faults and last know occurrence of seismic activity. Faults are mapped and categorized into by their potential for actual movement. Based on geologic site characterization, recommendations are made for increased seismic monitoring; age-dating studies of faults and geomorphic features; increased use of remote sensing and aerial photography for surface mapping of faults; the development of a landslide susceptibility map; and to develop seismic design standards for all existing and proposed facilities at LANL

    1980-01-01

    Economic analysis of the solar energy system installed at Loxahatchee, was developed for Loxahatchee and four other sites typical of a wide range of environmental and economic conditions in the continental United States. This analysis was accomplished based on the technical and economic models in the f Chart design procedure with inputs based on the characteristics of the installed system and local conditions. The results are expressed in terms of the economic parameters of present worth of system costs over a projected twenty year life, life cycle savings, year of positive savings and year of payback for the optimized solar energy system at each of the analysis sites. The sensitivity of the economic evaluation to uncertainties in constituent system and economic variables was also investigated. The results demonstrate that the solar energy system is economically viable at all of the five sites for which the analysis was conducted.

    The study of natural analogues has been established as one of the most important methods for validation of concepts and models applied for the assessment of long-term performance of repositories for nuclear waste. The objectives of such studies range from detailed investigations of processes and features on a small scale to attempts of explaining the evolution of whole sites. For studies of specific processes it may well be as important to consider the larger scale settings as boundary conditions. This appreciation of context and an integrated view may be as important for evaluation of most natural analogues as for performance assessments. This is more evident the more the evaluation depends on a knowledge about the evolution of the natural analogue. The attempted formulation of scenarios of the Koongarra Analogue has been based on the external conditions and external features. A rapid weathering of the host rock, i.e. the chlorite schist, is assumed to have started around the onset of the Pleistocene Ice Age (ca 1.6 Ma BP). The eventual oxidation and mobilization of the uranium ore could then have occurred under unsaturated or saturated conditions. This leads to the following major scenarios: (1) Uranyl Phosphates formed under unsaturated conditions, with a periodical evolution of the dispersion fan in conjunction with alternating dry (glacial) and wet (interglacial) periods during the Pleistocene Ice Age; (2) Uranyl Phosphates formed under unsaturated conditions as a single event, taking place either early or late during the Pleistocene Ice Age; (3)Uranyl Phosphates formed under saturated conditions, in conjunction with periods of higher and lower flow due to the climatic cycling. Although the original objectives may not have been fully achieved, this work is believed to contribute to a better understanding of the Koongarra Analogue as well as to give a basis for further scenario work

    1994-02-01

    This preapplication safety evaluation report (PSER) presents the results of the preapplication desip review for die Power Reactor Innovative Small Module (PRISM) liquid-mew (sodium)-cooled reactor, Nuclear Regulatory Commission (NRC) Project No. 674. The PRISM conceptual desip was submitted by the US Department of Energy in accordance with the NRC`s ``Statement of Policy for the Regulation of Advanced Nuclear Power Plants`` (51 Federal Register 24643). This policy provides for the early Commission review and interaction with designers and licensees. The PRISM reactor desip is a small, modular, pool-type, liquid-mew (sodium)-cooled reactor. The standard plant design consists of dim identical power blocks with a total electrical output rating of 1395 MWe- Each power block comprises three reactor modules, each with a thermal rating of 471 MWt. Each module is located in its own below-grade silo and is co to its own intermediate heat transport system and steam generator system. The reactors utilize a metallic-type fuel, a ternary alloy of U-Pu-Zr. The design includes passive reactor shutdown and passive decay heat removal features. The PSER is the NRC`s preliminary evaluation of the safety features in the PRISM design, including the projected research and development programs required to support the design and the proposed testing needs. Because the NRC review was based on a conceptual design, the PSER did not result in an approval of the design. Instead it identified certain key safety issues, provided some guidance on applicable licensing criteria, assessed the adequacy of the preapplicant`s research and development programs, and concluded that no obvious impediments to licensing the PRISM design had been identified.

  13. Safety requirements to be met in final storage of heat-producing waste an evaluation of the BMU draft

    International Nuclear Information System (INIS)

    The German Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU) on August 12, 2008 published a July 29, 2008 draft of the ''Safety Requirements to Be Met in Final Storage of Heat-producing Radioactive Waste.'' As announced by the BMU, these safety requirements are to bring up to the state of the art the safety criteria of 1983. Over a couple of years, efforts had been made to adapt the criteria to the internationally accepted standard as demanded by the Advisory Committees on Reactor Safeguards (RSK) and Radiation Protection (SSK). The main changes made by the BMU are the introduction of a phased procedure in building repositories. A phased plans approval procedure under the Atomic Energy Act has been foreseen by the Ministry for this purpose. In addition, the draft provides for the introduction of a risk-based goal of protection. To ensure retrievability of the waste, the casks are to have a demonstrated service life of 500 years. The BMU draft safety requirements are unable to bring the safety criteria of 1983 up to the current state of the art. Here are the key points of criticism: - A risk-based goal of protection is introduced. The yardstick to be applied is to be defined in a guideline yet to be elaborated. As a consequence, the draft lacks substance. - As in licensing of nuclear facilities, the licensing procedure provides for a phased plans approval procedure for exploration. This analogy does not exist, as exploration is not the first phase of the plant to be built but a measure which is a precondition for obtaining a permit for construction and operation. - The information contained in the draft indicates that, contrary to international recommendations, it tightens the goal of protection by more than one order of magnitude. - The requirements to be met by the casks because of retrievability impose constraints on solutions optimized for safety in emplacement technology. - The risk-based approach is not mature and is

    International Nuclear Information System (INIS)

    , detailed examination of the removed tube segments and correlation with the NDE data was completed. The examinations included post removal NDE with bobbin-coil EC. These EC inspections were performed both before and after tenacious copper rich OD surface deposits had been removed by chemical cleaning. Visual inspection of the clean tube surfaces with the aid of an optical microscope was the primary means for identifying tube defects. The OD surfaces of all specimens were inspected, while detailed examination of the ID surfaces was limited to those specimen locations where an ID defect had been reported or where ID cracking was expected. Metallography was performed on selected specimens to determine the nature and extent of tube degradation. Specimens removed from the hot leg top of tube sheet level of the generator with pitting/wastage type defects, along with tubes containing laboratory produced axial stress corrosion cracks, were burst tested to validate empirical models of remaining tube integrity. In addition, an evaluation of the publicly available leak rate data was conducted to determine if the leak rate could be correlated with crack length and fluid pressure differential across the tube wall. A mini-round robin using tube specimens with laboratory produced stress corrosion cracking was conducted. The objective of this activity was to acquire information to supplement the Surry data base. This was important since limited information regarding the EC inspection performance on crack type defects was obtained from the round robin examinations on the Surry generator. A tube bundle consisting of 18 tubes was sent to various firms that perform actual inservice inspections. Standard bobbin-coil and alternate NDE methods were evaluated. Analyses and Monte Carlo simulations were performed to compare and evaluate candidate ISI sampling plans. The measured EC performance from the round robin inspections was used to guide the selection of input parameters for this work

  15. Quantification of the reliability of personnel actions from the evaluation of actual German operational experience. Final report

    International Nuclear Information System (INIS)

    The results and their uncertainty bounds of PSA studies are considerably impacted by the assessment of human reliability. But the amount of available, generic data is not sufficient to evaluate all human actions considered in a modern PSA study adequately. Further the data are not sufficiently validated and rely as well as the proposed uncertainty bounds on expert judgement. This research project as well as the preceding project /GRS 10/ validated data recommended by the German PSA Guidelines and enlarged the amount of available data. The findings may contribute to an update of the German PSA Guidelines. In a first step of the project information about reportable events in German nuclear power plants with observed human errors (event reports, expert statements, technical documents, interviews and plant walk downs with subject matter experts from the plants) were analysed. The investigation resulted in 67 samples describing personal activities, performance conditions, the number of observed errors and the number of action performance. In a second step a new methodology was developed and applied in a pilot plant. The objective was to identify undoubtedly error free safety relevant actions, their performance conditions, and frequency as well as to prove and demonstrate that probabilistic data can be derived from that operational experience (OE). The application in the pilot plant resulted in 18 ''error free'' samples characterizing human reliability. All available samples were evaluated by use of the method of Bayes. That commonly accepted methodology was applied in order to derive probabilistic data based on samples taken from operational experience. A thorough analysis of the obtained results shows that both data sources (OE reportable events, OE with undoubtedly error free action performance) provide data with comparable quality and validity. At the end of the research project the following products are available. - Methods to select samples

    1996-02-01

    The Modular Electromechanical Lock Actuator (MELA) is the result of research and development (R&D) conducted under the direction of Dudley S. Childress, PhD, at the Northwestern University Prosthetics Research Laboratory (NUPRL), Chicago, Illinois. NUPRL, based upon experience with prostheses for persons with high-level, above-elbow amputations, developed the MELA to assist those persons with amputation who experience difficulty in operating existing manual elbows, whether with a conventional harness, nudge control, excursion amplifier, or other arrangement. Technology Transfer Section, VA Rehab R&D, with collaboration from Frederick Downs, Jr., Director, and John Clements, Prosthetic Regional Manager, VA National Prosthetic and Sensory Aids Service, managed a multicenter clinical evaluation of the MELA. The purpose was to objectively assess and affirm its performance, safety, clinical application, and commercial readiness. The following VA Prosthetic Treatment Centers served as evaluation sites: Baltimore, MD, Huntington, WV, and New York, NY. A VA-wide screening process yielded 10 candidates for review. A total of seven subjects met the selection criteria and were accepted for participation. In addition, several prosthetists provided their comments on the MELA. Overall, the performance of the MELA demonstrated that it could be fit to existing body-powered arms and used as an alternative control method for manual elbows. Consensus of participant feedback indicated general satisfaction and improved elbow lock function. In addition, several modifications were identified for the commercial version. The primary issues focused on 1) increasing speed (alternating response time); 2) unloading forearm (sometimes required to cycle the MELA); 3) providing mechanical back-up in case of unit failure; 4) reducing gear-motor noise; 5) improving integrity of wiring and retaining clip; and 6) marketing the MELA as a stand-alone product.

    1992-11-01

    The University of North Dakota Energy and Environmental Research Center (EERC) and the AMAX Research and Development Center are cooperating in the development of a Mild Gasification process that will rapidly devolatilize coals of all ranks at relatively low temperatures between 930{degree} and 1470{degree}F (500{degree}and 800{degree}C) and near atmospheric pressure to produce primary products that include a reactive char, a hydrocarbon condensate, and a low-Btu gas. These will be upgraded in a ``coal refinery`` system having the flexibility to optimize products based on market demand. Task 2 of the four-task development sequence primarily covered bench-scale testing on a 10-gram thermogravimetric analyzer (TGA) and a 1 to 4-lb/hr continuous fluidized-bed reactor (CFBR). Tests were performed to determine product yields and qualities for the two major test coals-one a high-sulfur bituminous coal from the Illinois Basin (Indiana No. 3) and the other a low-sulfur subbituminous coal from the Powder River Basin (Wyodak). Results from Task 3, on product upgrading tests performed by AMAX Research and Development (R&D), are also reported. Task 4 included the construction, operation of a Process Research Unit (PRU), and the upgrading of the products. An economic evaluation of a commercial facility was made, based on the data produced in the PRU, CFBR, and the physical cleaning steps.

    The Oklahoma Geological Survey (OGS), the Geo Information Systems department, and the School of Petroleum and Geological Engineering at the University of Oklahoma have engaged in a five-year program to identify and address Oklahoma`s oil recovery opportunities in fluvial-dominated deltaic (FDD) reservoirs. This program included a systematic and comprehensive collection and evaluation of information on all FDD oil reservoirs in Oklahoma and the recovery technologies that have been (or could be) applied to those reservoirs with commercial success. The execution of this project was approached in phases. The first phase began in January, 1993 and consisted of planning, play identification and analysis, data acquisition, database development, and computer systems design. By the middle of 1994, many of these tasks were completed or nearly finished including the identification of all FDD reservoirs in Oklahoma, data collection, and defining play boundaries. By early 1995, a preliminary workshop schedule had been developed for project implementation and technology transfer activities. Later in 1995, the play workshop and publication series was initiated with the Morrow and the Booch plays. Concurrent with the initiation of the workshop series was the opening of a computer user lab that was developed for use by the petroleum industry. Industry response to the facility initially was slow, but after the first year lab usage began to increase and is sustaining. The remaining six play workshops were completed through 1996 and 1997, with the project ending on December 31, 1997.

The objectives of the cooperation were to investigate the adequacy of RBMK shutdown systems with regard to shutdown effectiveness and shutdown rate and to compare the results of the respective calculations performed by the individual partners using their own computational techniques. It was not the intention to perform a comprehensive, representative safety analysis for the plant. The project was structured in three phases. Phase I: code, implementation and testing; phase II: steady state analysis of Smolensk-3; phase III: transient analysis of Smolensk-3. As a consequence of this project the reactor designer will eliminate the short-comings of the control and protection system and implement an additional diverse shutdown system in all RBMK. This system will utilize the present 24 fast acting shutdown rods in combination with a liquid poison system as an additional mean to shut the reactor down from any operational or accidental condition and to provide long term subcriticality. The reactor scram system (first shutdown system) will utilize the remaining rods to shut the reactor down quickly enough to cope with any accident and to maintain long term subcriticality. The new systems have been reported to be installed in Sosnoby Bor in 1997. (author) figs., tabs., 6 refs

  20. Demonstration and evaluation of the CORPEX trademark Nuclear Decontamination Process, Technical task plan No. SR152005. Final Report

    International Nuclear Information System (INIS)

    In June, 1995, the Decontamination and Decommissioning Focus Area funded a demonstration of the CORPEX Nuclear Decontamination Process in an Old Metallography Laboratory glovebox at the Savannah River Site. The objective of the demonstration was to prove the effectiveness of a new and innovative technology that would reduce the risks associated with future cleanups of plutonium-238 contaminated equipment in the DOE complex. After facility and vendor preparations in support of the demonstration, Westinghouse Savannah River Company (WSRC) was informed by the vendor that the chemistry proposed for use in the decontamination process was not effective on sintered plutonium, which was the form of plutonium in the selected glovebox. After further technical evaluation, the demonstration was canceled. This report describes the work performed in support of the demonstration and the present status of the project. The CORPEX chemical process is a nondestructive cleaning method that removes only the contaminant and the matrix that fixed the contaminant to the surface. It does not damage the substrate. The cleaning agent is destroyed by the addition of proprietary oxidizers, leaving water, carbon dioxide and nitrogen gases, and a sludge as waste

  1. Analysis of airborne radiometric data. Volume 1. Evaluation of the DELPHI/MAZAS computer code. Final report

    International Nuclear Information System (INIS)

    Testing and evaluation of the code MAZAS/DELPHI led to the following conclusions: its precision is better than the Window method for the analysis of uranium, comparable for the analysis of potassium, and worse for the analysis of thorium. Its accuracy of MAZAS is consistently better than the Window method when used on simulated data. The accuracy of the average values of the individual gamma-ray intensities obtained with MAZAS is good over the entire energy spectrum for the uranium and thorium spectra. The precision of the intensities of the low energy lines is poor unless 15 to 20 s integration times are used. Results of the analysis of actual flight data for potassium and thorium are very similar for MAZAS and the Window method. Results for uranium using MAZAS and the Window method appear to be different. MAZAS, which measures an average of several discrete gamma-ray components, seems to indicate considerably more airborne radon than the Window method. It is suspected that the Window method is measuring a combination of discrete and continuum components and that this is resulting in analyses that are inconsistent with MAZAS. The DELPHI time filter appears to work exceedingly well on simulated data. The accuracy of the method on actual flight data is uncertain

  2. QUANTOM - improved tumor diagnosis by quantitative evaluation of tomography data using digital 3D image processing. Final report

    International Nuclear Information System (INIS)

    Nonlinear techniques are applied to tasks in medical image processing. Using the so-called scaling index method and scaling vector method segmentation and detection algorithms are developed in order to recognise and measure tumors in three-dimensional tomographic data sets. It is shown that pulmonary nodules can well be detected in the lung only by analysing their morphological structure. Especially the nodules can be discriminated from the bronchovascular structures, which have the same intensity in the data sets. Newly developed segmentation algorithms, with which an exact volumetric assessment of tumors is made possible, are presented. It turns out that an algorithm, which combines elements from the watershed-transformation and from region growing techniques, yields the best results in terms of accuracy, transparency and reproducibility. The clinical valence of the volumetry is illustrated with studies concerning the response evaluation of tumors of the gastrointestinal tract during (chemo-)therapy. It turns out that the results obtained with an exact three-dimensional volume determination are in much better agreement with the histological gold standard than those obtained with simple conventional, planimetric measurements. Furthermore the specificity of the prediction for the response to a chosen therapy can be significantly increased using CT-volumetry and PET-measurements. Therefore, the number of therapeutically questionable operations can be reduced. Further possible fields of application for the newly developed methods are presented. (orig.)

  3. Air sampling system for evaluating the thyroid dose commitment due to fission products released from reactor containment. Final report

    International Nuclear Information System (INIS)

    Accidental releases of radioactivity from fission reactors will consist of active vapors and aerosols. Composition of the released plume or cloud will depend on the energy of release and fission product volatility. In accidents at Windscale and SL-1, 131I was the predominant isotope present in both the initial cloud and later release. Thus an air sampling system was developed for efficient radioiodine collection. The air sampling, readout, and dose assessment system was developed to be used in the environment after loss of containment accidents. The system can detect less than 1 rem dose commitments to thyroids of 5 year old children for immersion times of 10 hours or less. The air mover can be operated on either 110V ac power or 12V dc power available from vehicles with cigar lighter sockets. An inorganic silver loaded silica gel adsorber was developed for high mehyl iodine, HOI, and elemental iodine efficiency and low noble gas efficiency. A peal away high efficiency particulate filter permits the gaseous and particulate sample fractions to be evaluated separately. Predicted particulate iodine is combined with the adsorbed component to account for the total radioiodine in a given sample

  4. Evaluation of crushed aggregate and sand-bentonite mixtures for application to sealing of the final repository for reactor waste

    International Nuclear Information System (INIS)

    The Industrial Power Company Ltd (TVO) is planning to dispose the low- and intermediate level waste from the reactors of the Olkiluoto Nuclear Power Station into the bedrock of Olkiluoto at a depth of approximately 50-100 meters. In the TVO concept the reactor waste is disposed in silo shaped rock caverns. The bituminized waste is packed into steel drums, which are laid into a concrete silo inside the rock cavern. In this study the properties of sands, crushed aggregate and their mixtures with bentonite are reviewed. The applicability of these materials for use as a buffer on the top of the concrete silo is evaluated. This study is based on earlier experimental studies of the materials mentioned before and available literature. Gas production in the silo after disposal is estimated. General concepts of gas conductivity and gas migration in saturated soil are reviewed. The results of this study suggest that crushed aggregate and sand-bentonite mixtures are possible sealing materials for the silo in concern. But the need for further experimental study of their physical and mechanical properties and the gas migration processes through the saturated barrier is emphasized. A program for testing of these properties is presented

  5. Evaluation of shale hosted low-level waste disposal sites in semi-arid environments: Final report

    International Nuclear Information System (INIS)

    This report covers the findings of a multidisciplinary investigation intended to delineate critical factors and concerns associated with shale hosted, low-level radioactive waste disposal sites located in semiarid environments. The investigations focus primarily upon concerns regarding the hydrology, geochemistry, and meteorology of such an environment. The studies described within this report specifically do not constitute an evaluation of any one particular site nor even a particular class of sites. Rather, it is the intention of the report to present data and insights that would assist private concerns and governmental agencies in the efficient and prudent development of such disposal areas. This report assumes that the hypothetical waste site in question would be developed as a trench type operation similar to that used at Barnwell, South Carolina, with variations upon the techniques used at Beatty Flat, Nevada, and Hanford, Washington. The trench design (Figures 1 and 2) is assumed to be similar to that generic design described in ''Procedures and Technology for Shallow Land Burial, DOE/LLw-13Td, 1983) although it is also assumed that improvements and adaptations will be made upon this basic design to meet the individual needs of a particular site. During the preparation of this report it became apparent that new types of trench design are being studied. Discussions of these trench design proposals are not central to this report. The examples of trench design in Figures 1 and 2 are presented only to give an idea as to the general philosophy of construction of shallow burial facilities

  6. Final report of the NRC-Agreement State Working Group to evaluate control and accountability of licensed devices

    International Nuclear Information System (INIS)

    US NRC staff acknowledged that licensees were having problems maintaining control over and accountability for devices containing radioactive material. In June 1995, NRC approved the staff's suggestion to form a joint NRC-Agreement State Working Group to evaluate the problem and propose solutions. The staff indicated that the Working Group was necessary to address the concerns from a national perspective, allow for a broad level of Agreement State input, and to reflect their experience. Agreement State participation in the process was essential since some Agreement States have implemented effective programs for oversight of device users. This report includes the 5 recommendations proposed by the Working Group to increase regulatory oversight, increase control and accountability of devices, ensure proper disposal, and ensure disposal of orphaned devices. Specifically, the Working Group recommends that: (1) NRC and Agreement States increase regulatory oversight for users of certain devices; (2) NRC and Agreement State impose penalties on persons losing devices; (3) NRC and Agreement States ensure proper disposal of orphaned devices; (4) NRC encourage States to implement similar oversight programs for users of Naturally-Occurring or Accelerator- Produced Material; and (5) NRC encourage non-licensed stakeholders to take appropriate actions, such as instituting programs for material identification

  7. Evaluation of cerium oxide coated Cu cermets as inert anodes for aluminum electrowinning. Final report, August 1990--March 1992

    Energy Technology Data Exchange (ETDEWEB)

    1992-08-01

    Cu/NiFe{sub 2}O{sub 4} cermets were evaluated, with and without an in-situ deposited CEROX (TM; cerium oxide) coating, in 100 h laboratory A1 electrowinning tests. Bath ratio and current density were varied between tests and corrosion was determined by contamination of the aluminum and cryolite by cermet components (Cu, Fe, and Ni). Higher bath ratios of 1.5 to 1.6 led to less corrosion and thicker CEROX coatings. Lower current densities led to slightly less corrosion but much less oxidation of the Cu cermet substrate. At identical test conditions, the corrosion of the CEROX coated cermets was 1/7 that of an uncoated cermet. Corrosion was increased in CEROX coated cermets tested under unsaturated alumina conditions. The electrical conductivity of the CEROX coating was measured to be {approximately}0.2 ohm{sup {minus}1}cm{sup {minus}1}, resulting in a slight voltage penalty, depending on the thickness of the coating.

  8. Evaluation of juvenile salmonid bypass facilities and passage at water diversions on the lower Umatilla River. Final report

    International Nuclear Information System (INIS)

    Outdated juvenile and adult fish passage facilities were recently reconstructed at the five major irrigation dams on the lower Umatilla River, Oregon to meet National marine Fisheries Service (NMFS) design standards. Changes in design at juvenile fish bypass facilities included reduced mesh size on the rotating drum screens, larger screening area, a more oblique orientation of the drum screens to canal flow, improved screen seals, replacement of bypass portals with vertical slot bypass channels, and increased bypass pipe diameters. Weir-and-pool adult fish ladders and jump pools were replaced with vertical-slot ladders. From 1991--1995, they investigated injury and travel rate of juvenile fish moving through the facilities, and efficiency of screens in preventing fish entry into the canals. Water velocities in front of canal screens, at bypass channel entrances, and at ladder diffusers were measured to assess adherence to NMFS criteria and identify hydraulic patterns. Biological evaluations were conducted by releasing and recapturing marked yearling summer steelhead (Oncorhynchus mykiss), yearling spring chinook salmon (O. tshawytscha), and subyearling fall chinook salmon (O. tshawytscha) in varying locations within the fish passage facilities

    Urban air pollution is becoming a significant global problem, especially for large cities around the world. Traffic emissions contribute significantly to both elevated particle concentrations and to gaseous pollutants in cities. The latter also have the potential of forming more particulate mass via their photochemical oxidation in the atmosphere. The International Agency for Research on Cancer and the US EPA have characterised diesel exhausts as a likely human carcinogen that can also contribute to other health problems. In order to meet the challenges with increased transportation and enhanced greenhouse gas emissions, the European Union have decided on a 10% substitution of traditional fuels in the road transport sector by alternative fuels (e.g. biodiesel, CNG) before the year 2020. However, it is also important to study the influence of fuel switches on other primary pollutants as well as the potential to form secondary aerosol mass. This work focuses on the characterisation of the chemical composition of the gas and the condensed phase of fresh bus emissions during acceleration, in order to mimic the exhaust plume that humans would inhale under realistic conditions. In addition, photochemical aging of the exhaust emissions was achieved by employing a Potential Aerosol Mass (PAM) flow reactor, allowing the characterization of the composition of the corresponding aged emissions. The PAM reactor uses UV lamps and high concentrations of oxidants (OH radicals and O3) to oxidize the organic species present in the chamber. The oxidation that takes place within the reactor can be equivalent to up to one week of atmospheric oxidation. Preliminary tests showed that the oxidation employed in these measurements corresponded to a range from 4 to 8 days in the atmosphere. During June and July 2015, a total of 29 buses, 5 diesel, 13 CNG and 11 RME (rapeseed methyl ester), were tested in two different locations with limited influence from other types of emissions and traffic

  10. Compilation and evaluation of the available data on relevant mineral oil additives and their combustion products. Final report

    The objective of this study is to collect and evaluate environmentally relevant data on mineral oil additives and their combustion products. In addition, their concentration ranges, chemistry and functions in the mineral oils are described. Lubricant and fuel additives belong to the quantitatively most important chemicals with a total quantity of 84600 tons estimated for Germany 1997/98 (57400 tons of lubricant additives, 27200 tons of fuel additives). They determine substantially the characteristic profile of engine oils, gasoline and diesel. Main lubricant additive families are detergents, dispersants, antioxidant/antiwear agents (ZDTP), inhibitors, and viscosity modifiers. Examples for fuel additives are detergents, antioxidants, corrosion inhibitors, cetane improvers (diesel), and wax crystal modifiers (diesel). Based on the information available in the literature and provided by the manufacturers the environmental fate of the additives is explored, and inventories (calculations of the input and output) are presented. Data for emission volumes and additional 'reasonable worst case' assumptions were calculated on this basis. But as measurement data in this area is very limited, the calculated emissions are uncertain. Comparison of the emitted additive combustion products (CO{sub 2}, CO, NO{sub 2}, NMVOC, particulate matter) with exhaust limit values for tail pipe emissions and total traffic emissions in Germany showed that the contribution of additive combustion products to particles is more significant than to other fractions. The results of the calculations indicate that the portion of mineral oil additives of the traffic-dependent particle emissions in Germany is approximately 7% (ca. 3/5 from lubricant additives and ca. 2/5 from fuel additives).

  11. An experimental evaluation of the instrumented flux synthesis method for the real-time estimation of reactivity. Final report

    International Nuclear Information System (INIS)

    One method of determining the flux density is flux synthesis which approximates the flux in the core by linear combinations of precomputed shape functions. In traditional flux synthesis, the unknown mixing coefficients are determined using a weighted residual method of solving the diffusion equation. In the instrumented synthesis method, the mixing coefficients are determined using count rates from neutron detectors in the core. In this way the mixing coefficients are linked to conditions in the reactor. Using the synthesized flux, kinetics parameters, notably reactivity, can be calculated in real time. An experimental evaluation has been performed in the Massachusetts Institute of Technology Reactor, MITR-II. Detector measurements have been collected using fission chambers placed at the periphery of the core. The reactor was put into a number of various conditions, both static and transient, and data were collected using a digital acquisition system for later combination with shape functions. Transients included increasing power, decreasing power, and a reactor scram. The shape functions were generated using Version 3.0 of the QUARTZ code, a quadratic nodal diffusion theory code in triangular-Z geometry. Supernodal analysis algorithms have been added to the original program, along with subroutines to guarantee diagonal dominance of the leakage matrix in the finite difference or quadratic current approximations in the coarse mesh. The agreement between coarse mesh and fine mesh in all cases is excellent, with finite difference coarse mesh solutions generally slightly better. The synthesis method has been shown to accurately reflect the changes from an initial condition by combining representative flux shapes. It can be concluded that, with proper calibration of the measurement system and inclusion of representative flux shapes, the instrumented synthesis method will properly predict the flux in the core under a number of conditions

  12. Development and evaluation of a new depressurization spillage test for residential gas-fired combustion appliances : final report

    International Nuclear Information System (INIS)

    This paper presented a newly developed combustion depressurization spillage test for residential combustion appliances. The test uses carbon dioxide (CO2) that is produced in the fuel combustion process as a tracer gas. The test accurately measures the amount of combustion spillage from residential combustion appliances and their venting systems when they operate at certain levels of depressurization. Seven commonly used gas-fired appliances were used to evaluate the new test as well as the appliances. These included 2 power-vented storage-tank water heaters, 1 mid-efficiency furnace, 2 high-efficiency condensing furnaces, and 2 direct-vent gas fireplaces. Tests were performed for each unit with the test room initially depressurized by 50 Pa compared with the pressure outside the room. If the combustion spillage exceeded 2 per cent, the test was repeated with the room depressurized by 20 Pa, and then by 5 Pa. Each appliance was operated for 5 minutes of burner operation during which time the burner fuel consumption, the concentration of CO2 and the exhaust fan flow rate were monitored. Measurements were taken for 2 minutes following burner shut off. The amount of CO2 that was released into the test room from the appliance and its venting system was determined from the measurements and then compared with the amount of CO2 that would be produced by combustion of the fuel that was consumed during the test. The ratio of the 2 provided a direct measure of the combustion spillage of the appliance and its venting system. The study revealed that 3 products had undetectable levels of combustion spillage, 3 products had low, but measurable combustion spillage, and 1 product had significant combustion spillage. refs., tabs., figs

    A feasibility study was initiated to determine if downstream migrant salmonids could be monitored to determine potential relationships between total dissolved gas (TDG) exposure and signs of gas bubble trauma (GBT). The primary objectives were to: (1) establish logistical requirements for in-river monitoring of TDG exposure, including net pen design, deployment, and navigation constraints; (2) resolve uncertainties associated with effects of the net pen on fish behavior; (3) test the accuracy and precision of in-river monitoring equipment used to measure fish distribution and water quality; and (4) determine the application of hydrologic/flow models to predictions of TDG exposure. In-river measurements included water velocity, boat position, and selected water quality parameters (temperature, dissolved oxygen, pH, depth, conductivity). Fish distribution within the net pen was monitored using scanning sonar, and a split-beam echo sounder was used to evaluate vertical distribution of fish m in the river adjacent to the net pen. Three test drifts were conducted from late July through late August. The studies demonstrated that it was feasible to assemble and deploy a large net pen for mobile monitoring of TDG exposure. Accurate monitoring of vertical and lateral distribution of smolts was performed, and diel differences in behavior were documented. Further, the fish sounded in response to researcher activity on the perimeter platform. Thus, in-transit monitoring for GBT or mortality would affect fish depth distribution and exposure to TDG. Principal recommendations for future studies are directed at improving maneuverability of the net pen in adverse weather conditions and applying new acoustics technology to simultaneously collect fish distribution data from within and outside of the pen. 6 refs., 17 figs., 2 tabs.

  14. Final Report on Evaluating the Representation and Impact of Convective Processes in the NCAR Community Climate System Model

    Energy Technology Data Exchange (ETDEWEB)

    X. Wu, G. J. Zhang

    2008-04-23

    Convection and clouds affect atmospheric temperature, moisture and wind fields through the heat of condensation and evaporation and through redistributions of heat, moisture and momentum. Individual clouds have a spatial scale of less than 10 km, much smaller than the grid size of several hundred kilometers used in climate models. Therefore the effects of clouds must be approximated in terms of variables that the model can resolve. Deriving such formulations for convection and clouds has been a major challenge for the climate modeling community due to the lack of observations of cloud and microphysical properties. The objective of our DOE CCPP project is to evaluate and improve the representation of convection schemes developed by PIs in the NCAR (National Center for Atmospheric Research) Community Climate System Model (CCSM) and study its impact on global climate simulations. • The project resulted in nine peer-reviewed publications and numerous scientific presentations that directly address the CCPP’s scientific objective of improving climate models. • We developed a package of improved convection parameterization that includes improved closure, trigger condition for convection, and comprehensive treatment of convective momentum transport. • We implemented the new convection parameterization package into several versions of the NCAR models (both coupled and uncoupled). This has led to 1) Improved simulation of seasonal migration of ITCZ; 2) Improved shortwave cloud radiative forcing response to El Niño in CAM3; 3) Improved MJO simulation in both uncoupled and coupled model; and 4) Improved simulation of ENSO in coupled model. • Using the dynamic core of CCM3, we isolated the dynamic effects of convective momentum transport. • We implemented mosaic treatment of subgrid-scale cloud-radiation interaction in CCM3.

  16. Evaluation of Lepidoptera population suppression by radiation induced sterility. Proceedings of a final research co-ordination meeting

    International Nuclear Information System (INIS)

    This publication results from the second FAO/IAEA Research Co-ordination Project (CRP) on Inherited Sterility in Lepidoptera (caterpillars of moths). The present CRP and a previous one entitled 'Radiation Induced F1 Sterility in Lepidoptera for Area-Wide Control' were initiated in response to requests from Member States for the development of environment friendly alternatives to current control of moth pests. The first five-year CRP (1987-1991) dealt primarily with aspects such as determining the effects of various radiation dose levels on the resulting sterility in the treated parents and their F1 progeny in different Lepidoptera species. In addition, models were developed on the suppressive effects of F1 sterility on field populations, and some studies were conducted in laboratory or field cages to assess the impact of inherited sterility on pest suppression. The research results were published in 1993 in the IAEA Panel Proceedings Series. This follow-up CRP (1994-1998) has built on the results of the first CRP and has focused on addressing a more challenging phase, consisting of rearing key pest moths and evaluating their application for pest control purposes. The specific objective of the CRP was therefore to assess the potential of suppressing populations of caterpillar pests in the field by inherited sterility methods, i.e. by rearing and releasing irradiated moths and/or their progeny in combination with other biological control methods. The ultimate goal is to have alternative environment-friendly control methods available to be able to reduce the vast quantities of insecticide that are used in agriculture to combat Lepidoptera pests and that adversely affect the trade balance of developing countries because they must use hard currency to import them. The two FAO/IAEA sponsored Lepidoptera CRPs have resulted in expanded research and implementation programmes on F1 sterility in combination with natural enemies. Such programmes are under way in Tunisia for

  17. Evaluation of airborne geophysical surveys for large-scale mapping of contaminated mine pools: draft final report

    Decades of underground coal mining has left about 5,000 square miles of abandoned mine workings that are rapidly filling with water. The water quality of mine pools is often poor; environmental regulatory agencies are concerned because water from mine pools could contaminate diminishing surface and groundwater supplies. Mine pools are also a threat to the safety of current mining operations. Conversely, mine pools are a large, untapped water resource that, with treatment, could be used for a variety of industrial purposes. Others have proposed using mine pools in conjunction with heat pumps as a source of heating and cooling for large industrial facilities. The management or use of mine pool water requires accurate maps of mine pools. West Virginia University has predicted the likely location and volume of mine pools in the Pittsburgh Coalbed using existing mine maps, structure contour maps, and measured mine pool elevations. Unfortunately, mine maps only reflect conditions at the time of mining, are not available for all mines, and do not always denote the maximum extent of mining. Since 1999, the National Energy Technology Laboratory (NETL) has been evaluating helicopter-borne, electromagnetic sensing technologies for the detection and mapping of mine pools. Frequency domain electromagnetic sensors are able to detect shallow mine pools (depth < 50 m) if there is sufficient contrast between the conductance of the mine pool and the conductance of the overburden. The mine pools (conductors) most confidently detected by this technology are overlain by thick, resistive sandstone layers. In 2003, a helicopter time domain electromagnetic sensor was applied to mined areas in southwestern Virginia in an attempt to increase the depth of mine pool detection. This study failed because the mine pool targets were thin and not very conductive. Also, large areas of the surveys were degraded or made unusable by excessive amounts of cultural electromagnetic noise that obscured the

    The disposal systems of radioactive residuals well-known as repositories near to the surface, are used to dispose residuals that can contain high concentrations of radionuclides of period of short semi disintegration, which they would decay at levels radiologically insignificant in some few decades or in some centuries: and acceptably low concentrations of radionuclides of period of long semi disintegration. The dose that would receive the critic group due to these systems it could be increased by cause of discreet events that affect the foreseen retard time, or by the gradual degradation of the barriers. To this last case it contributes the presence of water, because it implies leaching and dissolution that can give place to radionuclide concentrations in the underground water greater to the prospective ones. The dosimetric evaluation is important because it offers useful objective information to decide if a given repository is adjusted to the purposes of its design and it fulfills the regulatory requirements. In this work a simplified evaluation of the dose that would receive the critic group due to the liberation of contained radionuclides in a hypothetical system of final disposition of radioactive residuals is presented. For it, they are considered representative values of the usually contained activities in this type of systems and they are carried out some approaches of the source term. The study is developed in two stages. In the first one, by means of the Radionuclide pollutant scattering pattern in phreatic aquifers (DRAF) it is considered the scattering of the pollutants in the phreatic aquifer, until the discharge point in the course of the nearest surface water. This model, developed originally in the regulatory branch of the National Commission of Argentine Atomic Energy (CNEA); it solves the transport equation of solutes in porous means in three dimensions, by the finite differences method having in account the soil retention and the radioactive

    The Franklin Research Center (FRC), a Division of the Franklin Institute, was contracted by the Bureau of Mines to improve walking dragline roller tracks. The contract was subsequently transferred to the Department of Energy. The period from September 1977 to September 1978 covered laboratory rolling contact rig tests to evaluate typical low hardness dragline track materials. The results of this work are covered by DOE/ET/9121-1 Final Report, Volume I. The period from September 1978 to July 1980 covered field measurements of dragline roller circle loadings. The results of this work are covered by DOE/ET/9121-2 Final Report, Volume II. The laboratory rolling contact rig test results indicate that forged vacuum degassed air melt steel materials are recommended over air-melt cast materials for rollers and tracks. The steels tested exhibited good freedom from sensitivity to stress raisers like brinell marks and small holes or discontinuities (Volume I). The largest unknown in a recommended method for life testing roller tracks is the condition of the upper rotating frame structure and the lower tub supporting structure.

  20. Spent-Fuel Test - Climax: An evaluation of the technical feasibility of geologic storage of spent nuclear fuel in granite: Executive summary of final results

    International Nuclear Information System (INIS)

    This summary volume outlines results that are covered in more detail in the final report of the Spent-Fuel Test - Climate project. The project was conducted between 1978 and 1983 in the granitic Climax stock at the Nevada Test Site. Results indicate that spent fuel can be safely stored for periods of years in this host medium and that nuclear waste so emplaced can be safely retrieved. We also evaluated the effects of heat and radiation (alone and in combination) on emplacement canisters and the surrounding rock mass. Storage of the spent-fuel affected the surrounding rock mass in measurable ways, but did not threaten the stability or safety of the facility at any time

    The U. S. Department of Energy (DOE) methods and protocols allow evaluation of remediation and final site conditions to determine if remediated sites remain protective. Two case studies are presented that involve the Niagara Falls Storage Site (NFSS) and associated vicinity properties (VPs), which are being remediated under the Formerly Utilized Sites Remedial Action Program (FUSRAP). These properties are a part of the former Lake Ontario Ordnance Works (LOOW). In response to stakeholders concerns about whether certain remediated NFSS VPs were putting them at risk, DOE met with stakeholders and agreed to evaluate protectiveness. Documentation in the DOE records collection adequately described assessed and final radiological conditions at the completed VPs. All FUSRAP wastes at the completed sites were cleaned up to meet DOE guidelines for unrestricted use. DOE compiled the results of the investigation in a report that was released for public comment. In conducting the review of site conditions, DOE found that stakeholders were also concerned about waste from the Separations Process Research Unit (SPRU) at the Knolls Atomic Power Laboratory (KAPL) that was handled at LOOW. DOE agreed to determine if SPRU waste remained at that needed to be remediated. DOE reviewed records of waste characterization, historical handling locations and methods, and assessment and remediation data. DOE concluded that the SPRU waste was remediated on the LOOW to levels that pose no unacceptable risk and allow unrestricted use and unlimited exposure. This work confirms the following points as tenets of an effective long-term surveillance and maintenance (LTS&M) program:  Stakeholder interaction must be open and transparent, and DOE must respond promptly to stakeholder concerns.  DOE, as the long-term custodian, must collect and preserve site records in order to demonstrate that remediated sites pose no unacceptable risk.  DOE must continue to maintain constructive relationships

  3. Hy-NOW. Evaluation of methods and technologies for the production of hydrogen based on biomass. Final Report

    International Nuclear Information System (INIS)

    The conversion of biomass is considered an important option for supplying the future mobility sector with sustainable hydrogen. In this study, various processes and technologies are evaluated that are suitable for a biomass-based production of hydrogen. This includes thermochemical processes such as the gasification of biomass in fixed bed, fluidized bed and entrained-flow gasification and the reforming of secondary bioenergy carriers (e.g. biogas), as well as biochemical processes such as the fermentation of biomass to hydrogen, and the photolysis of water. Following a fundamental prescreening of the processes, three of them are identified as the most promising options for a short or medium-term realization within a demonstration plant. Plant and supply concepts for these processes are defined and analyzed in detail. Two of the concepts are based on allothermal fluidized bed gasification (concepts 1 and 2) and the third one on steam reforming of biogas (concept 3). The hydrogen production capacity amounts to 9 MWH2 (270 kgH2/h) with concept 1, 3 MWH2 (90 kgH2/h) with concept 2 and 6 MWH2 (180 kgH2/h) with concept 3. The hydrogen production and supply concepts are analyzed based on their technical, economic and environmental performance as well as on the availability of the raw materials (biomass) required. For each of the concepts assessed, the availability of feedstock is sufficient to allow for the realization of demonstration plants. Significant parts of the existing biomass potentials, however, are used for other applications already. Hence, thorough examination of potential demonstration sites is crucial, giving due consideration to regional or local raw material availabilities Overall, there are advantages for gasification-based concepts as far as feedstocks are concerned. The technical assessment shows disadvantages for the fermentation-based plant concept in the net efficiency of the hydrogen production, i.e. the conversion efficiency from biomass to

    We compiled the results of the source analysis obtained under the collaboration research. Recent construction scheme for source modeling adopted in Japan is described, and strong-motion prediction is performed assuming the scenario earthquakes occurring in the Ulsan fault system, Korea. Finally Qs values beneath the Korean inland crust are estimated using strong-motion records in Korea from the 2005 Off West Fukuoka earthquake (M7.0). Probabilistic seismic hazard for four NPP sites in Korea are evaluated, in which the site specific attenuation equations with Index SA developed for NPP sites are adopted. Furthermore, the uniform hazard spectra for the four NPP sites in Korea are obtained by conducting the PSHA by using the attenuation equations with the index of response spectra and seismic source model cases with maximum weights. The supporting tools for seismic response analysis, the evaluation tool for evaluating annual probability of failure, and system analysis program were developed for the collaboration. The tools were verified with theoretical results, the results written in the reference document of EQESRA, and so forth. The system analysis program was applied for the investigation of the effect of improving the seismic capacity of equipment. We evaluated the annual probability of failure of isolated and non-isolated EDG at Younggwang NPP site as the results of the collaboration. The input ground motion for generating the seismic fragility curve was determined based on the seismic hazard analysis. It was found that the annual probability of failure of isolated EDG is lower than that of non-isolated EDG.

    Full Text Available Background: During endodontic procedures, the smear layer is formed as a result of mechanical instrumentation of the canal. Combination of ethylenediamine tetraacetic acid (EDTA and sodium hypochlorite (NaOCl is widely used for removal of the smear layer. Application of Mixture of tetracycline, acid, and detergent (MTAD as final irrigant subsequent to initial irrigation of 1.35% NaOCl has been proposed to increase clinical efficiency, biocompatibility and prolonged intra-canal antibacterial activity. Considering the importance of adhesion of endodontic sealers to the dentin walls of a prepared root canal, the present study evaluated push-out bond strength of AH26 sealer using final irrigation of MTAD and EDTA + NaOCl. Materials and Methods: Sixty five single-rooted teeth were prepared endodontically with the same chemomechanical technique and were randomly divided into three groups based on their final irrigation regimen: 17% EDTA + 5.25% NaOCl group (n = 30, MTAD group (n = 30 and control group (n = 5. Obturation of the canals was performed with gutta-percha and AH26 sealer. All teeth were sectioned in order that two specimens of 1 mm thickness were obtained from the coronal and the middle one third of each root resulting in 60 specimens for each experimental group and 10 specimens for control group. For push-out test, universal-testing machine was used to exert a constant compressive apico-coronal load at a speed of 0.5 mm/min. Minimum amount of compressive load caused dislodgement was measured and converted into megapascal (MPa scale. One-way analysis of variance and the post hoc Tukey test were used for statistical analysis of the data (α = 0.05. Results: In MTAD group, mean micro-push-out bond strength of AH26 sealer to dentin walls was obtained 2.23 MPa compared to 2.0 MPa for EDTA + NaOCl group. The mean bond strength of AH26 sealer to dentin walls was significantly greater using MTAD compared with combination of EDTA and NaOCl or saline

  12. Fuel-Cycle energy and emission impacts of ethanol-diesel blends in urban buses and farming tractors

    International Nuclear Information System (INIS)

    About 2.1 billion gallons of fuel ethanol was used in the United States in 2002, mainly in the form of gasoline blends containing up to 10% ethanol (E10). Ethanol use has the potential to increase in the U.S. blended gasoline market because methyl tertiary butyl ether (MTBE), formerly the most popular oxygenate blendstock, may be phased out owing to concerns about MTBE contamination of the water supply. Ethanol would remain the only viable near-term option as an oxygenate in reformulated gasoline production and to meet a potential federal renewable fuels standard (RFS) for transportation fuels. Ethanol may also be blended with additives (co-solvents) into diesel fuels for applications in which oxygenation may improve diesel engine emission performance. Numerous studies have been conducted to evaluate the fuel-cycle energy and greenhouse gas (GHG) emission effects of ethanol-gasoline blends relative to those of gasoline for applications in spark-ignition engine vehicles (see Wang (and others) 1997; Wang (and others) 1999; Levelton Engineering (and others) 1999; Shapouri (and others) 2002; Graboski 2002). Those studies did not address the energy and emission effects of ethanol-diesel (E-diesel or ED) blends relative to those of petroleum diesel fuel in diesel engine vehicles. The energy and emission effects of E-diesel could be very different from those of ethanol-gasoline blends because (1) the energy use and emissions generated during diesel production (so-called ''upstream'' effects) are different from those generated during gasoline production; and (2) the energy and emission performance of E-diesel and petroleum diesel fuel in diesel compression-ignition engines differs from that of ethanol-gasoline blends in spark-ignition (Otto-cycle-type) engine vehicles. The Illinois Department of Commerce and Community Affairs (DCCA) commissioned Argonne National Laboratory to conduct a full fuel-cycle analysis of the energy and emission effects of E-diesel blends relative

    Two natural gas buses in Malmoe have in a project been converted to run on mixtures of hydrogen and natural gas. The buses have been in operation from September 2003 to December 2005 and have during the whole extent of the project been in commercial operation with passengers. One bus has been refuelled with a mixture containing 8% hydrogen and another with 25% hydrogen. One of the buses has during limited periods been refuelled with natural gas in order to establish differences in fuel consumption between the different fuels. A number of different supporting activities have been performed in conjunction to the project: Tests at the Lund Univ. with hydrogen addition to natural gas in a one cylinder test engine and in a 6 cylinder natural gas engine. Safety analysis for handling of hydrogen/natural gas blends. Hydrogen compatibility study of material and components in bus fuel system. Test of leak detection systems for hydrogen and hydrogen/natural gas blends. Development of safety routines for operation and maintenance staff. Emission measurement during road operation with mobile equipment. Follow up of filling station for hydrogen/natural gas blends. The results from the projects are: The buses did not need to be modified in any way in order to run on mixtures with up to 8 vol-% hydrogen. The buses could, in less than 4 h, be modified to run on mixtures with 25 vol-% hydrogen. The conversion was accomplished by changing one computer chip in the engine control system, thus altering the air/fuel ratio and adjusting the ignition angle. The fuel consumption of the buses was reduced by 20-30% by hydrogen addition. The largest relative influence was achieved with 8% hydrogen addition. The reduced fuel consumption in combination with reduced carbon content in the fuel resulted in a total reduction in CO{sub 2}-emission by approximately 35% using 8% hydrogen (by volume). Addition of hydrogen to natural gas has thus proved to be a more efficient way of reducing CO{sub 2

    Alinejad, Yasaman

    One of the most challenging issues that the technologies related to nanomaterials face is the impact they have on human health and environment. It is therefore of great importance to investigate the toxicological impacts of these technologies prior to their widespread utilization in different fields of application. Therefore, in this study, the cytotoxicity of the materials present throughout the process of single-walled carbon nanotubes (SWCNTs) synthesis by induction thermal plasma (from the feedstock materials to the final product) was evaluated. First of all, the influence of the induction thermal plasma process on the physico-chemical and cytotoxic properties of feedstock materials (i.e. commercial Co, Ni, Y2O3, Mo catalysts and carbon black) was investigated. The strongest cytotoxicity was observed for commercial Co compared to other catalysts. Although the thermal plasma process affected the properties of all catalysts, only the cytotoxicity of Ni was increased. Comparing the properties and cytotoxicity of the plasma treated Ni particles with commercial Ni nanoparticles revealed that the particles with similar surface area had different cytotoxicities. Plus, the observed cytotoxicity of the catalysts was not mainly due to the release of ions. In order to evaluate the capacity of the RF induction thermal plasma process to produce high quality SWCNTs using non-toxic catalysts, the effects of the type and quantity of three catalyst mixtures (Ni-Y2O 3, Ni-Co-Y2O3, and Ni-Mo-Y2O3 ) on SWCNTs synthesis were examined. Thermodynamic calculations, in gas and particularly in liquid solution phases, were also performed. The results showed that catalyst type affected the quality of the SWCNT final product and similar quality SWCNTs was produced when the same amount of Co was replaced by Ni. Then, to investigate the cytotoxicity of the SWCNTs produced with the three catalyst mixtures, their effect was evaluated on the behavior of murine MC3T3-E1 preosteoblasts. Either

    measurements, data analyses, modeling, meta-analysis, and reanalysis of previously collected data sets. We identified a set of 12 ancillary hypotheses regarding habitat and salmon response. Each ancillary hypothesis states that the response metric will trend toward conditions at relatively undisturbed reference sites. We synthesized the evidence for and against the two necessary conditions by using eleven causal criteria: strength, consistency, specificity, temporality, biological gradient, plausibility, coherence, experiment, analogy, complete exposure pathway, and predictive performance. Our final evaluation included cumulative effects assessment because restoration is occurring at multiple sites and the collective effect is important to salmon recovery. We concluded that all five lines of evidence from the LCRE indicated positive habitat-based and fish-based responses to the restoration performed under the CEERP, although tide gate replacements on small sloughs were an exception. Our analyses suggested that hydrologic reconnections restore access for fish to move into a site to find prey produced there. Reconnections also restore the potential for the flux of prey from the site to the main stem river, where our data show that they are consumed by salmon. We infer that LCRE ecosystem restoration supports increased juvenile salmon growth and enhanced fitness (condition), thereby potentially improving survival rates during the early ocean stage.

The program focused on a Si{sub 3}N{sub 4}-4% Y{sub 2}O{sub 3} high temperature ceramic composition and hot-isostatic-pressing as the method of densification. Stage I had as major objectives: (1) comparing injection molding and colloidal consolidation process routes, and selecting one route for subsequent optimization, (2) comparing the performance of water milled and alcohol milled powder and selecting one on the basis of performance data, and (3) adapting several NDE methods to the needs of ceramic processing. The NDE methods considered were microfocus X-ray radiography, computed tomography, ultrasonics, NMR imaging, NMR spectroscopy, fluorescent liquid dye penetrant and X-ray diffraction residual stress analysis. The colloidal consolidation process route was selected and approved as the forming technique for the remainder of the program. The material produced by the final Stage II optimized process has been given the designation NCX 5102 silicon nitride. According to plan, a large number of specimens were produced and tested during Stage III to establish a statistically robust room temperature tensile strength database for this material. Highlights of the Stage III process demonstration and resultant database are included in the main text of the report, along with a synopsis of the NCX-5102 aqueous based colloidal process. The R and D accomplishments for Stage I are discussed in Appendices 1--4, while the tensile strength-fractography database for the Stage III NCX-5102 process demonstration is provided in Appendix 5. 4 refs., 108 figs., 23 tabs.

    Full Text Available [english] Aims: Due to the discontinuation of the 18-month practical period called "Arzt im Praktikum" students need to be fit for their job as hospital doctors earlier than they used to which is supposed to be achieved by a change of the German curriculum towards a more practical approach. After a needs assessment by focus groups a training scheme for students in their final year matching these needs was being established and assessed at the Medical Hospital Heidelberg. Methods: We established a training scheme composed of four units: (1 Medical didactics, (2 time-management and training on ward rounds, (3 and difficult communication situations (4 on ward. These trainings were attended by 21 final year students from May to July 2005. Outcomes: The students were highly satisfied with the individual training units (values ranging from 1.56±0.81 to 1.93±1.16 / 1= "excellent", 6= "insufficient". The qualitative analysis of the questionnaire comments also shows a consistently positive response. Especially the communication and ward round trainings were seen as being "close to reality", and it was considered very "sensible" training to practise difficult situations in a simulated setting at first. Conclusion: For the final year students, an important training segment for future medical work, options for clinical-practical training schemes, adequate in difficulty and setting, were established. This is a first step towards a curriculum for the final year.

    The Pacific Northwest Electric Power Planning and Conservation Act of 1980 indicated ''The council shall properly develop and adopt a program to protect, mitigate, and enhance fish and wildlife, including related spawning grounds and habitat on the Columbia River and its tributaries.'' As a result, the Bonneville Power Administration (BPA) has spent millions of dollars on various instream projects throughout the Columbia Basin with the goal of increasing system-wide production of anadromous fisheries through a combination of habitat restoration and enhancement measures. For two decades, numerous BPA-funded projects have been initiated in the upper Columbia River Basin for the express intent of improving the aquatic habitats of anadromous salmonids. Largely missing from most of these projects has been any rigorous evaluation of project success or failure. Some field reviews of some habitat projects have been undertaken (e.g., Beschta et al. 1991, Kauffman et al. 1993) and provide an overview of major problems and opportunities associated with selected projects. However, there continues to be a lack of quantifiable information, collected in a systematic manner that could be used as the basis for scientifically assessing the effects of individual projects on riparian/aquatic habitats, functions, or processes. Recent publications (e.g., NRC 1992, ISG 1996, NRC 1996, Beschta 1997, and Kauffman et al. 1997) have identified and summarized important concepts associated with the restoration and improvement of aquatic ecosystems. While such conceptual approaches provide an important structure for those undertaking restoration efforts, there remains a paucity of basic information throughout the upper Columbia Basin on the hydrologic, geomorphic, and biologic responses that occur from various enhancement approaches. Basic data on the spatial and temporal responses of restoration approaches would provide: (1) a better understanding of project effects upon

    The Alternative Fuels for Vehicles Fleet Demonstration Program (AFV-FDP) was a multiyear effort to collect technical data for use in determining the costs and benefits of alternative-fuel vehicles in typical applications in New York State. During 3 years of collecting data, 7.3 million miles of driving were accumulated, 1,003 chassis-dynamometer emissions tests were performed, 862,000 gallons of conventional fuel were saved, and unique information was developed about garage safety recommendations, vehicle performance, and other topics. Findings are organized by vehicle and fuel type. For light-duty compressed natural gas (CNG) vehicles, technology has evolved rapidly and closed-loop, electronically-controlled fuel systems provide performance and emissions advantages over open-loop, mechanical systems. The best CNG technology produces consistently low tailpipe emissions versus gasoline, and can eliminate evaporative emissions. Reduced driving range remains the largest physical drawback. Fuel cost is low ($/Btu) but capital costs are high, indicating that economics are best with vehicles that are used intensively. Propane produces impacts similar to CNG and is less expensive to implement, but fuel cost is higher than gasoline and safety codes limit use in urban areas. Light-duty methanol/ethanol vehicles provide performance and emissions benefits over gasoline with little impact on capital costs, but fuel costs are high. Heavy-duty CNG engines are evolving rapidly and provide large reductions in emissions versus diesel. Capital costs are high for CNG buses and fuel efficiency is reduced, but the fuel is less expensive and overall operating costs are about equal to those of diesel buses. Methanol buses provide performance and emissions benefits versus diesel, but fuel costs are high. Other emerging technologies were also evaluated, including electric vehicles, hybrid-electric vehicles, and fuel cells.

    This study evaluates the costs and benefits associated with the use of a plug-in hybrid electric bus and determines the cost effectiveness relative to a conventional bus and a hybrid electric bus. A sensitivity sweep analysis was performed over a number of a different battery sizes, charging powers, and charging stations. The net present value was calculated for each vehicle design and provided the basis for the design evaluation. In all cases, given present day economic assumptions, the conventional bus achieved the lowest net present value while the optimal plug-in hybrid electric bus scenario reached lower lifetime costs than the hybrid electric bus. The study also performed parameter sensitivity analysis under low market potential assumptions and high market potential assumptions. The net present value of plug-in hybrid electric bus is close to that of conventional bus.

    随着网络的高速发展,其信息资源越来越庞大,面对巨量的信息库,搜索引擎起着重要的作用。主题爬虫技术作为搜索引擎的主要核心部分,计算搜索结果与搜索主题的关系,该关系被称为相关性。一般主题爬虫方法只计算网页内容与搜索主题的相关性,作者所提主题爬虫,通过链接内容和锚文本内容计算链接的重要性,然后利用贝叶斯分类器对链接进行分类,最后利用余弦相似函数计算网页的相关性,如果相关值大于阀值,则认为该网页与预定主题相关,否则不相关。实验结果证明:所提出主题爬虫方法可以获得很高的精确度。%With the rapid development of the network,its information resources are increasingly large and faced a huge amount of information database, search engine plays an important role. Focused crawling technique, as the main core portion of search engine,is used to calculate the relationship between search results and search topics,which is called correlation. Normally,focused crawling method is used only to calculate the correlation between web content and search related topics. In this paper, focused crawling method is used to compute the importance of links through link content and anchor text,then Bayesian classifier is used to classify the links,and finally cosine similarity function is used to calculate the relevance of web pages. If the correlation value is greater than the threshold the page is considered to be associated with the predetermined topics, otherwise not relevant. Experimental results show that a high accuracy can be obtained by using the proposed crawling approach.

  14. Exhaust emissions evaluation of Colombian commercial diesel fuels

    International Nuclear Information System (INIS)

    Ecopetrol, based on the results obtained in the study, The effect of diesel properties on the emissions of particulate matter (Bello et al 2000), reformulated the diesel fuel distributed in Bogota, becoming it lighter and with lower sulfur content. In order to evaluate the environmental benefits that the reformulation of diesel fuel generate in Bogota, Instituto Colombiano del Petroleo (ICP), with the assistance of emissions research and measurement division (ERMD) from environment Canada, arranged a research project to determine the changes in CO, THC, NOx, CO2 and particulate matter emissions. The research program was developed in two steps. First one, developed in Bogota, involved a fleet test with 15 public service buses that normally operate in Bogota's savannah, using a portable emissions sampling technology developed for ERMD (DOES2) and following a representative transient driving cycle. Second step, carried out in ERMD's Heavy-Duty engine emissions laboratory in Ottawa, tested a 1995 caterpillar 3406E 324/5 KW (435 HP) diesel truck engine on the same samples of Colombian diesel fuels used in the fleet tests performed in Bogota, baselining the tests with a Canadian commercial low sulfur diesel fuel. The two commercial Colombian diesel fuels used had the following properties: High Sulfur Diesel (HSD), with 3000 ppm (0,3 wt %) of sulfur and a final boiling point (FBP) of 633 K and the new reformulated diesel fuel, with 1000 ppm (0,1 wt %) of sulfur and FBP of 613 K, which is currently been distributed in Bogota. Fleet test show small reduction on CO, THC and TPM, and small increments on CO2 and NOx but with not statistically significant results, while engine testing shows a strong reduction of 40/8% in TPM when you use the new reformulated diesel fuel (0,1 wt % of sulfur) instead of high sulfur diesel

    Fatigue-related crashes have long been the topic of discussion and study worldwide. The relationship between fatigue-related crashes and time of day is well documented. In Malaysia, the possibility of banning express buses from operating during the early-hours of the morning has emerged as an important consideration for passenger safety. This paper highlights the findings of an impact assessment study. The study was conducted to determine all possible impacts prior to the government making any decision on the proposed banning. This study is an example of a simple and inexpensive approach that may influence future policy-making process. The impact assessment comprised two major steps. The first step involved profiling existing operation scenarios, gathering information on crashes involving public express buses and stakeholders' views. The second step involved a qualitative impact assessment analysis using all information gathered during the profiling stage to describe the possible impacts. Based on the assessment, the move to ban early-hour operations could possibly result in further negative impacts on the overall road safety agenda. These negative impacts may occur if the fundamental issues, such as driving and working hours, and the need for rest and sleep facilities for drivers, are not addressed. In addition, a safer and more accessible public transportation system as an alternative for those who choose to travel at night would be required. The proposed banning of early-hour operations is also not a feasible solution for sustainability of express bus operations in Malaysia, especially for those operating long journeys. The paper concludes by highlighting the need to design a more holistic approach for preventing fatigue-related crashes involving express buses in Malaysia. PMID:22239931

    Full Text Available Objectives: To determine if a pharmacist assisted psychiatric clinic would improve adherence to medications and quality of life over 6 months. The primary study endpoints were the change from baseline in Medication Adherence Rating Scale (MARS, Brief Evaluation of Medication Influences and Beliefs (BEMIB, World Health Organization Quality of Life - BREF (WHOQOL-BREF scales as well as hospitalizations and emergency room visits. Secondary endpoints included metabolic and physiologic parameters.Methods: A prospective, single-center study conducted at an outpatient psychiatric clinic. Subjects were required to attend 3 clinic visits (baseline, 3 and 6 months with the pharmacist. Subject and medication histories were obtained at each visit. Subjects’ records within the local health system were reviewed for emergency room visits and hospitalizations. Metabolic parameters were assessed at each visit.Results: Twenty-seven subjects enrolled and twenty subjects completed. Total MARS score at baseline and study end were 7.90 and 8.65, respectively. At baseline, 10 (50% were nonadherent based on the BEMIB and 9 (45% were nonadherent at 6 months. Statistically significant improvements were seen in 2 domains of the WHOQOL-BREF. Reductions in both ER visits and hospitalizations were achieved. There were significant improvements in total cholesterol and LDL.Conclusions: Improvements were seen in two domains of the WHOQOL-BREF – physical capacity and psychological well-being over the 6 month period. While improvements were seen in various rating scales, due to small sample sizes, these were insignificant improvements. Reductions in hospitalizations and ER visits were also seen during the study and up to 6 months post study. Statistically significant improvements were also seen in both total cholesterol and LDL. The lack of improvement in many of the study outcomes reflects the difficulty of the mental health population to adhere to treatment recommendations

    This protocol is designed to evaluate the fate in ground water of chlorinated aliphatic hydrocarbons and/or fuel hydrocarbons. The data collected under this protocol can be used to compare the relative effectiveness of other remedial options and natural attenuation. This protocol should be used to evaluate whether monitored natural attenuation by itself or in conjunction with other remedial technologies is sufficient to achieve site-specific remedial objectives. Understanding the contaminant flow field in the subsurface is essential for a technically justified evaluation of a monitored natural attenuation remedial option; therefore, use of this protocol is not appropriate for evaluating monitored natural attenuation at sites where the contaminant flow field cannot be determined with an acceptable degree of certainty (e.g., complex fractured bedrock, karst aquifers).
