    In today’s uncertain and turbulent markets, supply chain vulnerability has become an issue of significance for many companies. As supply chains become more complex as a result of global sourcing and the continued trend to ‘leaning-down’, supply chain risk increases. The challenge to business today is to manage and mitigate that risk through creating more resilient supply chains.

    Timber supply has traditionally been modelled using aggregate data. In this paper, we build aggregate supply models for four roundwood products for the US state of North Carolina from a stand-level harvest choice model applied to detailed forest inventory. The simulated elasticities of pulpwood supply are much lower than reported by previous studies. Cross price elasticities indicate a dominant influence of sawtimber markets on pulpwood supply. This approach allows predicting the supply conse...

    Full Text Available It is irrefutable that the construction industry is in need of a highly technological construction method or system for the simple aim of giving it a push it deserves. In Malaysia this technologically enhanced method is known as the Indutrialised Building System (IBS. Concerted efforts have been made for the past decade by various responsible parties especially by the government. Therefore, the IBS ‘Road Map’ 2003–2010 was introduced and now continues with the IBS ‘road map’ 2011-2015. However, its performance is still at its infancy, which target is only at an initial stage. This study seeks to identify and analyse the factor of the IBS’ system’s supply chain flexibility as a factor on the success of the system itself. It has been a suspicion that there exists a condition and situation where the supply chain is too rigid and is not flexible in fulfilling the needs and demands of the IBS development in Malaysia. This inflexible situation has brought about a broad range of problems and has stood in the way of the development of the industrialised building system, despite it being introduced since 1964, or 49 years ago. Flexibility in the IBS supply chain is very important and is associated with other industries like transportation, manufacturing industry, and others. Up until now, we have yet to discover any special studies related to the flexibility in the IBS supply chain in this country. Responding to this challenge, this research is hoped to be able to provide sufficient feedback to the solution to the IBS supply chain flexibility issue. The researcher is confident that the poor system flow of supply chain has impeded the advancement of the Industrialised Building System that has long been open to debate.

    Trigeneration systems, also known as Combined Heat, Cooling and Power (CHCP) systems, are interesting alternatives to supply different energy services in urban districts and in large buildings, particularly in warm areas such as Mediterranean countries. These systems can provide substantial benefits from economic, energetic, and environmental viewpoints, since the cogenerated heat can be used for heating in winter as well as cooling in summer with an absorption refrigerator. This paper develops an optimization model using Mixed Integer Linear Programming (MILP) to determine the type, number and capacity of equipment in CHCP systems installed in the tertiary sector as well as to establish the optimal operation mode for the different plant components on an hour-by-hour basis throughout the year. The objective function to be minimized is the annual total cost. The optimization model considers the legal constraints imposed to feed the surplus autogenerated electricity into the grid at a regulated feed-in tariff. The optimization model is applied to design a system providing energy services for a hospital located in the city of Zaragoza (Spain). The effects of the financial market conditions and energy prices in the optimal structure of the system are analyzed. (author)

    Full Text Available Supply chain relationships play a significant role in supply chain management to respond to dynamic export market changes. If the dyadic exporter-producer relationships are still weak, they impede the emergence of a high performance supply chain within an export market. This paper develops a conceptual framework for understanding how exporter-producer relationships include not only the relationship system but also network and transaction systems; and thus introduces a more integrated way of looking at supply chain management based on information sharing as a key process between exporters and producers. To achieve this aim, supply chain relationships are reviewed from the perspectives of relationship marketing theory, network theory and transaction cost theory. Findings from previous research are discussed to provide a better understanding of how these relationships have evolved. A conceptual framework is built by offering a central proposition that specific dimensions of relationships, networks and transactions are the key antecedents of information sharing, which in turn influences export performance in supply chain management.

  15. Building sustainable supply chains: consumer choice or direct management?

    Energy Technology Data Exchange (ETDEWEB)

    Hebditch, David; Blackmore, Emma

    2012-06-15

    Putting a 'carbon label' on products to show how much carbon dioxide is emitted during their production, transport and disposal has been heralded as a powerful route to sustainability within companies' supply chains. Several leading firms have joined the Carbon Trust carbon labelling scheme over the past five years, including UK-based retail giant Tesco, which as early as 2007 promised to use carbon labels on all its products. But earlier this year, the multinational said it was dropping carbon labels and instead directly managing its supply chains. Many other companies are similarly choosing direct management over consumer choice as the most effective route to emission reductions. In so doing, they are shouldering greater responsibility for the emissions and impacts of their supply chains. But environmental concerns must not be allowed to trump development needs and companies must not unfairly disadvantage smaller-scale producers in developing countries.

  1. Energy efficiency of elevated water supply tanks for high-rise buildings

    International Nuclear Information System (INIS)

    Highlights: ► We evaluate energy efficiency for water supply tank location in buildings. ► Water supply tank arrangement in a building affects pumping energy use. ► We propose a mathematical model for optimal design solutions. ► We test the model with measurements in 22 Hong Kong buildings. ► A potential annual energy saving for Hong Kong is up to 410 TJ. -- Abstract: High-rise housing, a trend in densely populated cities around the world, increases the energy use for water supply and corresponding greenhouse gas emissions. This paper presents an energy efficiency evaluation measure for water supply system designs and a mathematical model for optimizing pumping energy through the arrangement of water tanks in a building. To demonstrate that the model is useful for establishing optimal design solutions that integrate energy consumption into urban water planning processes which cater to various building demands and usage patterns, measurement data of 22 high-rise residential buildings in Hong Kong are employed. The results show the energy efficiency of many existing high-rise water supply systems is about 0.25 and can be improved to 0.26–0.37 via water storage tank relocations. The corresponding annual electricity that can be saved is 160–410 TJ, a 0.1–0.3% of the total annual electricity consumption in Hong Kong.

    2015-10-01

    As suggested by UNEP, the key to sustainable development is to create a "green economy" which should encapsulate all three sectors: the industry, the people, and the government. Therefore, there is an urgent need to develop and implement the green technologies into the existing facilities, especially in the developing countries. In this study, the role of green supply chains in eco-industrial parks (EIPs) towards a green economy was investigated. The strategies and effective evaluation procedures of the green economy were proposed by assessing the barriers from the perspective of institution, regulation, technology, and finance. In addition, three case studies from iron and steel-making, paper mill and pulping, and petrochemical industries were presented and illustrated for building the green supply chains. For example, in the case of Lin-Hai Industrial Park, a total of 15 efficient green supply chains using waste-to-resources technologies were established by 2012, resulting in an economic benefit of USD 100 million per year. It suggests that the green supply chains should be established to achieve both economic growth and environmental protection. With these successful experiences, building a green supply chain within industrial park should be extensively promoted to make traditional industries around the world being environmentally bearable, economic viable, and social equitable.

  15. Management of hybrid energy supply systems in buildings using mixed-integer model predictive control

    International Nuclear Information System (INIS)

    Highlights: • Management of a heating supply system for buildings with storage tank is optimized. • Mixed-integer model predictive controller for hybrid energy supply is proposed. • Efficient management of a stratified storage tank is provided. • Unit commitment problem with switching heat pump is solved for heat load prediction. • Excellent and robust performance is guaranteed by extensive analysis of parameters. - Abstract: In this paper a mixed-integer model predictive controller for hybrid energy supply systems in buildings is presented. This approach is based on a hierarchical building control concept where the energy supply level is coupled to the energy consumption level only by the heat load. The supply level is characterized by non-linear dynamics due to a stratified water storage tank and a switched heat pump with minimum on/off times. The mixed-integer model predictive controller optimizes the unit commitment problem at minimum costs while satisfying the consumption level’s predicted heat load. The hybrid system is formulated as a piecewise affine model comprising continuous and discrete system inputs. Moreover, the proposed controller is able to manage the stratified storage tank including switching sequences of the heat pump with respect to energy price forecasts. The effectiveness of this approach is shown by a comparison to a model predictive controller with an a priori fixed operation mode profile, where the heat pump is only operating at night, and discussing the effect of the variation of the stratified storage tank size. The proposed concept is able to flexibly manage all sizes of stratified storage tanks with better performance than the reference control strategy, which is only effective for larger tanks. Additionally, a robustness analyses demonstrates that the mixed-integer model predictive controller can handle errors in the heat load prediction from the consumption level. Both analyses show promising results for the practical use

The energy sources for this system, the IWESS, are solar radiation and bioDiesel fuel. The components of this overall system are: (1) a solar driven cooling and heating system for the IW comprising solar receivers, an absorption chiller, heat recovery exchanger, and circulation pump; (2) a bioDiesel fueled engine generator with heat recovery exchangers, one on the exhaust to provide steam and the other on the engine coolant to provide heated water; (3) a ventilation system including an enthalpy recovery wheel, an air based heat pump, an active desiccant wheel, and an air circulation fan; and (4) various convective and radiant cooling/heating units and ventilation air diffusers distributed throughout the IW. The goal of the ABETI/IWESS project is to demonstrate an energy supply system for a building space that will provide a healthy, comfortable environment for the occupants and that will reduce the quantity of energy consumed in the operation of a building space by a factor of 2 less than that of a conventional energy supply for power, cooling, heating, and ventilation based on utility power and natural gas fuel for heating.

    Growing concerns on environmental problems related to current energy use have emphasized the importance of ''energy-saving measures'' and the necessity for an increased efficiency in all forms of energy utilization. Being responsible for around 40% of the final energy use in Germany, buildings are major contributors to energy related problems and a sector where a more rational and efficient energy use is absolutely necessary. By showing the thermodynamic efficiency of an energy system, exergy analysis is expected to be a valuable tool for developing and designing more efficient energy supply systems in buildings, similarly as it has contributed to raise the efficiency of power plants. In this thesis, the usability and added value of exergy analysis applied to different building energy systems is investigated. Exergy analysis is, herefore, compared to conventional primary energy assessment and the different results and conclusions obtained from both methods are thoroughly studied and discussed.

    Full Text Available This study involves a financial analysis of 43 publicly listed and large private companies in the building and construction supply chain from 2005 to 2010; straddling the period of the global financial crisis (GFC; and examines the impact of the GFC on the performance of these companies. The construction supply chain was divided into four sectors – material suppliers, construction companies, property developers and real estate investment trusts (REITs. The findings indicate that the impact was minimal for both material suppliers and construction companies, but especially severe for the more leveraged property developers and REITs. Building material suppliers and construction companies have benefitted substantially from the building economic stimulus package provided by the Australian government to mitigate the effects of the GFC. Decreases in the valuation of assets have, to a large extent, reduced the profitability of property developers and REITs during the GFC but these companies have recovered quickly from these adverse conditions to return to a sound financial position by the end of the 2010 financial year. The results will inform investors, managers and construction professionals in devising strategies for prudent financial management and for weathering future financial crises.

    A method is described for quantifying the reentrainment of exhaust air contaminants into a building's fresh-air supply system. The method relies on the "tracer" gas, sulfur hexafluoride (SF6), which Is detected by infrared (IR) absorption analysis. This method of analysis differs from the conventional gas chromatography, electron capture detection method due to the MIRAN-1 A's portability, direct-reading capabilities, ease of operation and modest cost. Specific instrument settings for the MIRAN-1 A are given such that detection of SF6 will be optimized without interference. Calculations for quantifying reentrainment are presented and discussed for the "worst case" reentrainment observed. PMID:6624644

    Full Text Available Rise in comfort and inhabitation safety is one of the main requirements of the general maintenance, reconstruction of the old and construction of the new residential houses. One of the essential factors of it is substitution in the household hot-water preparing sources: from the individual domestic gas  water-heaters to  the common  entire-building hot-water supply at the expense of the centralized heat supply. Extremely erratic hot-water daily consumption by tenants leads to the necessity of sharp increase in central heat-supply level during a few hours of the day, which requires a significant increase of the source heat-power. On that score, the authors propose to direct a significant part (up to 50 % of the centralized heating and ventilation heat power-consumption to the hot water preparation during the period of short-term hot water consumption peak.Substitution  of  the  individual  domestic  gas  water-heaters  with  the  common  entirebuilding hot-water supply releases a huge amount of natural gas which can be utilized not only for production of the necessary heat power but as well for electric power producing. This substitution is especially advantageous if heat-power is delivered to the residential area from a НРС where significant part of heat especially in a relatively warm season of the year is thrown out into the air. The content of the article is based on several patents received earlier.

    Full Text Available A water supply system of a special purpose is a necessary element in hot and cold shops of the industrial enterprises, office buildings and the medical centers, and also other rooms. The water supply systems of a special purpose, which give subsalty, sparkling water and water sated with oxygen, allow people to prevent, for example, strong dehydration of an organism, which is possible at big losses of water, especially in case of the people working in hot shops. Various elements of special drinking water supply system are given in the article, their main functions are described. Different types of the water folding devices pumping water to consumers, one of which is drinking fountain, are considered. Possible systems of water filtration, which can be established for quality improvement, are transferred. Among them the great role is played by membrane technologies and the return osmosis, which is widely applied now. Today there is a possibility of construction, both the centralized water supply system of a special purpose, and local. Besides, the least is a more preferable option taking into account capital expenditure for construction and operation, and also it can lead to solid resource-saving as a result of the electric energy saving going for water heating in heaters. Automatic machines of drinking water for a local water supply system of a special purpose have indisputable advantages. They are capable to carry out several functions at the same time, and also to distribute water to consumers. It allows placing all the necessary equipment, which will be well in harmony with the environment in their small and compact case, and will fit into any difficult interior of the room. Also they are very easily connected to the systems of an internal water supply system by means of a propylene tube that allows to change their sposition in space and to transfer to any place of the room with fast installation of equipment. Also the ecological effect was

  10. A First Approach to Natural Thermoventilation of Residential Buildings through Ventilation Chimneys Supplied by Solar Ponds

    2015-07-01

    Full Text Available The exploitation of natural ventilation is a good solution to improve buildings from an energetic point of view and to fulfill the requirements demanded by the thermohygrometric comfort and the air quality in enclosed spaces. Some past researches demonstrated how some devices, useful to this purpose, follow the principles of solar chimneys and are able to move air masses while exploiting the Archimedes thrust. The natural ventilation must be supplied by a flow moving upward, generated by a heat source performing at temperatures slightly higher than the one present in the environment. To have a minimum energetic effect, the heat can be extracted from solar ponds; solar ponds are able to collect and store solar energy in the geographical regions characterized by sufficient values of solar radiation. Thus it is possible, in summer, to provoke a nocturnal natural ventilation useful for the air change in indoor spaces (in those climatic areas where, during the night, there is a temperature gradient.

    In addressing sustainability issues for the built environment, focus is often directed towards minimising energy consumption and material use. Often forgotten however, is the potential for the integration of sustainable solutions when designing water and waste management systems for buildings. The fundamental functions of such systems are clearly recognised, but traditional design principles often constrain opportunities for performance enhancement and for water and pipework economies. To an extent, this is unsurprising, given the basic premise that steady-state analysis of flows underpins many of the codes and guidelines used worldwide. However, advances in simulation methods mean that system performance resulting from the use of new techniques and from the integration of innovative and more sustainable design approaches can now be fully assessed. This paper provides an overview of the water supply and drainage systems for buildings whose performance has been assessed through the development, at Heriot-Watt University, of a suite of numerical simulation models. These models accurately predict, using appropriate forms of the St. Venant equations, the pressure and flow regime within such systems by applying the Method of Characteristics finite difference technique. The paper provides three different examples of application, where the focus of each is on embedding sustainability in design. (author)

    In the future, buildings will not only act as consumers of energy but as producers as well. For these ''prosumers'', energy production by use of solar panels, photovoltaics and heat pumps etc will be essential. The objective of this project was to find the most optimal combinations of building insulation and use of renewable energy sources in existing buildings in terms of economics and climate impacts. Five houses were analyzed based on different personal load, consumption profiles, solar orientation and proposed building envelope improvements and use of combinations of renewable energy systems. The present report describes typical construction details of the building envelope (windows, floor, outside wall and roof/ceiling) for houses built in the years 1961-1972, 1973-1978 and 1979-1998. Furthermore the report describes the necessary improvements for the buildings' U-value to be the minimum value as stated in the Danish building code of 2010, and to be the values for buildings at the level of low-energy class 2015. Cost estimation for optimizing the houses to an optimum insulation level has been made. (ln)

    Full Text Available As consisted with Directive No 3 of President of the Republic of Belarus of June, 14th 2007 ‘Economy and Husbandry – the Major Factors of Economic Security of the Republic of Belarus’, saving fuel-and-energy resources over the republic in 2010–2015 should amount to 7,1–8,9 MIO tons of fuel equivalent including 1,00–1,25 MIO tons of fuel equivalent at the expense of heat-supply optimization and 0,25–0,40 MIO tons of fuel equivalent at the expense of increasing enclosing structures heat resistance of the buildings, facilities and housing stock. It means, where it is expected to obtain around 18 % of general thermal resources economy in the process of heat-supply optimization, then by means of enhancing the cladding structure heat resistance of the buildings and constructions of various applications – only about 3–5 % and even a bit less so of the housing stock. Till 1994, in residential sector of the Republic of Belarus, the annual heat consumption of the heating and ventilation averaged more than 130 kW×h/(m2×year (~56 %, of the hot-water supply – around 100 kW×h/(m2×year (~44 %. In residential houses, built from 1994 to 2009, heat consumption of the heating and ventilation is already 90 kW×h/(m2×year, of the hot-water supply – around 70 kW×h/(m2×year. In buildings of modern mainstream construction, they expend 60 kW×h/(m2×year (~46 % on heating and ventilation and 70 kW×h/(m2×year (~54 % on hot-water supply. In some modern residential buildings with the exhausted warm air secondary energy resource utilization, the heating and ventilation takes around 30–40 kW×h/(m2×year of heat. Raising energy performance of the residential buildings by means of reducing heat expenses on the heating and ventilation is the last segment in the system of energy resources saving. The first segments in the energy performance process are producing heat and transporting it over the main lines and outside distribution networks. In

  5. Optimum testing intervals of building emergency power supply systems in tall buildings in the Hong Kong Special Administrative Region

    Science.gov (United States)

    Kwok, Yu Fat

    The main objective of this study is to develop a model for the determination of optimum testing interval (OTI) of non-redundant standby plants. This study focuses on the emergency power generators in tall buildings in Hong Kong. The model for the reliability, which is developed, is applicable to any non-duplicated standby plant. In a tall building, the mobilisation of occupants is constrained by its height and the building internal layout. Occupant's safety, amongst other safety considerations, highly depends on the reliability of the fire detection and protection system, which in turn is dependent on the reliability of the emergency power generation plants. A thorough literature survey shows that the practice used in determining OTI in nuclear plants is generally applicable. Historically, the OTI in these plants is determined by balancing the testing downtime and reliability gained from frequent testing. However, testing downtime does not exist in plants like emergency power generator. Subsequently, sophisticated models have taken repairing downtime into consideration. In this study, the algorithms for the determination of OTI, and hence reliability of standby plants, are reconsidered. A new concept is introduced into the subject. A new model is developed for such purposes which embraces more realistic factors found in practice. System aging and the finite life cycle of the standby plant are considered. Somewhat more pragmatic is that the Optimum Overhauling Interval can also be determined from this new model. System unavailability grow with time, but can be reset by test or overhaul. Contrary to fixed testing intervals, OTI is determined whenever system point unavailability exceeds certain level, which depends on the reliability requirement of the standby system. An optimum testing plan for lowering this level to the 'minimum useful unavailability' level (see section 9.1 for more elaboration) can be determined by the new model presented. Cost effectiveness is

    Full Text Available In the present study, we have developed an optimal heat supply algorithm which minimizes the heat loss through the distribution pipe line in a group energy apartment. Heating load variation of a group energy apartment building according to the outdoor air temperature was predicted by a correlation obtained from calorimetry measurements of all households in the apartment building. Supply water temperature and mass flow rate were simultaneously controlled to minimize the heat loss rate through the distribution pipe line. A group heating apartment building located in Hwaseong city, Korea, which has 1473 households, was selected as the object building to test the present heat supply algorithm. Compared to the original heat supply system, the present system adopting the proposed control algorithm reduced the heat loss rate by 10.4%.

The present report describes how person and consumption profiles used in this project are developed, and which data that form the basis for these profiles. The increasing requirements for energy in the building sector mean that the primary energy consumption ends close to or below zero within the next years. Therefore, the consumption in buildings becomes a relatively larger and larger part of the total energy demand in dwellings. It is important to investigate whether there are seasonal distributions of power and water consumption, because it might give a more exact result and describe the reality better than by using yearly values. First, the personal load determined, and then humidity and consumption of both power and hot water is defined. Second, the hourly profiles are developed based on analyses of seasonal distributions. These profiles also include cold domestic water to see whether there is a correlation between this and hot domestic water. (ln)

    Most of the energy required by residential buildings is for low temperature heat. Often this demand is met by the use of high quality energy sources such as fossil fuels and electricity. The energy analysis alone does not take into account the quality of energy and so it hides the real potential for the so-called energy savings. Thus the concept of exergy must be involved. In particular the low-exergy approach shows that the energy with low exergy level has to be supplied with energy with sim...

  12. Estimates of U.S. Commercial Building Electricity Intensity Trends: Issues Related to End-Use and Supply Surveys

    Energy Technology Data Exchange (ETDEWEB)

    Belzer, David B.

    2004-09-04

    This report examines measurement issues related to the amount of electricity used by the commercial sector in the U.S. and the implications for historical trends of commercial building electricity intensity (kWh/sq. ft. of floor space). The report compares two (Energy Information Administration) sources of data related to commercial buildings: the Commercial Building Energy Consumption Survey (CBECS) and the reporting by utilities of sales to commercial customers (survey Form-861). Over past two decades these sources suggest significantly different trend rates of growth of electricity intensity, with the supply (utility)-based estimate growing much faster than that based only upon the CBECS. The report undertakes various data adjustments in an attempt to rationalize the differences between these two sources. These adjustments deal with: 1) periodic reclassifications of industrial vs. commercial electricity usage at the state level and 2) the amount of electricity used by non-enclosed equipment (non-building use) that is classified as commercial electricity sales. In part, after applying these adjustments, there is a good correspondence between the two sources over the the past four CBECS (beginning with 1992). However, as yet, there is no satisfactory explanation of the differences between the two sources for longer periods that include the 1980s.

  14. Using air-conditioning waste water and stormwater as supply management in a commercial building, case study

    Full Text Available The concept of rational use as applied to water conservation consists in managing water supply and demand by trying to meet lesser quality water demands with alternative or reused water supply. This project attempts to demonstrate the application of a system that uses water drained from air conditioning system evaporators and rainwater as alternative sources. Given that each evaporator produces 4.80 liters of water per hour and considering the average use of an air conditioning system to be approximately 10 hours per day, the daily total of a single evaporator would be 48 liters. This would implicate a daily volume of 4,298 liters for the whole 137 units spread throughout the building, which in time would represent 77.72% of the daily demand of wastewater (5,53 liter/day. For the rainwater collection system, the total accumulated volume corresponds to 10% of the site area multiplied by a factor of 0.05, for a retention time of 1 hour, which will produce a total volume 14.8m³ of water. This system´s primary objective is to significantly reduce the consumption of potable water, which nowadays is used for every single activity, thus contributing to a more sustainable building and minimizing the environmental impact caused by the construction.

    The temperature regime inside a building has been calculated. It has been established that the presence of a lateral pipeline at the heat point ensures such a value of the mixing coefficient at which a constant comfortable temperature of 24°C is attained. When this pipeline is absent, the comfortable temperature may not be attained at any values of the mixing coefficient. Consideration has been given to the problem on determination of the optimum dependence of the average velocity of the heat-transfer agent in the heating system on the mixing coefficient. The notion of an ideal temperature chart has been introduced.

In contrast to focus on workflow as is more common in construction, Systematic Production Analysis (SPA is a tool capable of providing a more robust production process in terms of better resource characterisation and predictability. A roadmap model, composed of six steps, has been developed for simple introduction of SPA. The model is a straightforward way of classifying the production system in terms of impacting resource and parameters attributing to production loss (scrap or downtime. The applicability of SPA is analysed through a pilot case study at a patio door manufacturer. Two main response parameters emerged related to scrap; surface and dimension errors of the work piece material (wood. An objective function was formulated to reduce the scrap without increasing the total cost of the work piece material. It was suggested that the case company evaluates Engineering Wood Products (EWP leading to a more robust production process (less scrap, but in turn increasing the initial cost of the work piece material. Other potential measures are purchasing new processing tools, investing in new machinery or educating workers which all, directly or indirectly, lead to reduced scrap. Consequently, proper management of production resources will improve their predictability and in turn improve production control.

The following process equipment modules would be prefabricated for installation at the modified dock: an AHF cylinder enclosure, an AHF supply manifold and vaporizer module, an AHF sump tank and transfer skid, and an AHF supply off-gas scrubber assembly module. The fluidized-bed reactor system would be constructed in an area adjacent to the existing system in Building 9212. The replacement equipment would consist of a new reduction fluidized-bed reactor, a hydrofluorination fluidized-bed reactor, and associated air emission control equipment. The no-action alternative, which is the continued operation of the existing AHF supply and fluidized-bed reactor systems, was also evaluated.

    Full Text Available In the field of biomass and bio-energy production, an analysis was performed of the whole production process from biomass supply to bio-energy production. The available biomass, harvesting and transportation costs and the distribution of supply area were quantified. The assessment of volumes was based on forest type and its relative increment. The transportation costs, influenced by different species-specific and site-specific factors, were calculated by integrating data in a geographic information system (GIS. The economic values calculated were the main economic indicators (net present value (NPV, internal rate of return (IRR and Payback Period. The results show that: (a there is a good supply of forest biomass across most of the territory of Basilicata region, Italy; (b the harvesting and transportation costs are dependent on biomass density and distances; (c there are strong margins for economic profits at the level of each single supply basin; and (d the endogenous value added was estimated to about 150 seasonal workers.

The countries examined in this study are the United Kingdom and Romania. The results attest that due to various historical, political, competition, and electricity market structural conditions Romania and the United Kingdom have emerged with different models for new build nuclear projects. This paper begins with an assessment of the effects on the nuclear sector from energy, environmental and competition legislation in the EU. Then the political and economic climate of the aforementioned EU member states is completed. Following this an overview of the market structure of the electricity sector in those respective countries is conducted. Then the key research on the models and the phases of new nuclear build are explored. The research concludes each model has transcended from different political and economic forces, and consequently each model has met with varied levels of success. Electricity market structures while operating to the same legal requirements, have been dissimilar in their evolution. The combination of the above factors has led to different models for new nuclear build. Upon further analysis it is concluded and demonstrated that the Romanian financing model cab stated to be more stable and provides an example for any new nuclear build aspiring nations in the EU and beyond.

    The US Department of Energy (DOE) proposes to replace the existing anhydrous hydrogen fluoride (AHF) supply and fluidized-bed reactor systems for the Weapons Grade Highly Enriched Uranium Chemical Recovery and Recycle Facility, Building 9212, which is Iocated within the Y-12 Plant on DOE`s Oak Ridge Reservation in Oak Ridge, Tennessee. The current AHF supply and fluidized-bed reactor systems were designed and constructed more than 40 years ago. Because of their deteriorating condition, the corrosive nature of the materials processed, and the antiquated design philosophy upon which they are based, their long-term reliability cannot be assured. The current AHF supply system cannot mitigate an accidental release of AHF and vents fugitive AHF directly to the atmosphere during operations. the proposed action would reduce the risk of exposing the Y-12 Plant work force, the public, and the environment to an accidental release of AHF and would ensure the continuing ability of the Y-12 Plant to manufacture highly enriched uranium metal and process uranium from retired weapons for storage.

    The periodic stationwide outage at Darlington NGS includes removal of the Emergency Coolant Injection System from service to allow for maintenance. As a prerequisite, the station must set up a minimum 2.5 kg/s temporary makeup water supply, to help cool the fuel should a seismic event occur. This modification cannot be commissioned, as commissioning would dilute the heavy water in the Primary Heat Transport System with light water. Therefore, flow analysis is necessary to demonstrate that the required flow rate can be achieved. This paper provides details of the design, and key aspects of the supporting analysis. (author)

    Full Text Available Domestic rainwater harvesting (DRWH is widely recognized as an alternative source of water in Taiwan because of water shortages. This suggests that rainwater potential should be maximized and quantified. In this article, we assess the potential of DRWH at a national level. To consider the climatic, building characteristic, economic, and ecological aspects of DRWH, we propose three categories: (1 theoretical; (2 available; and (3 environmental bearable rainwater potential. Four main steps were followed to develop the proposed framework: (1 Fifteen rainfall zones across Taiwan were generated through cluster analysis based on the average annual 10-day rainfall distributions of rainfall stations and administrative districts; (2 The roof area in each rainfall zone was estimated using a geographic information system (GIS and land use classification database; (3 The weighted percentage of rainwater use in each rainfall zone was determined by the optimal point on the storage capacity and rainwater supply reliability curve for an equivalent building from each building type; (4 The percentage of the total roof area used to harvest rainwater in each region depends on the downstream impact of the stream flow. The procedures developed in this study constitute an effective tool for preliminarily estimation of the national DRWH potential.

    Full Text Available Access to essential medicines continues to be a challenge in most developing countries and is among the Millennium Development Goals targets . Over the past decade, international programs, including the Global Fund to Fight Aids, Tuberculosis and Malaria, the World Bank, the United States Agency for International Development, among others, have led to improved access to essential medicines, particularly those for HIV/AIDS, malaria and tuberculosis. For instance, GAVI by end of 2013 had US$8.2 million in pledges for new and underused vaccines, while the Global Fund to Fight AIDS, Tuberculosis and Malaria had received a total of $30.5 billion in pledges and $25.6 billion in contributions . In addition to these, the President’s Emergency Plan for AIDS Relief (pepfar [4], had US$3.2 billion for HIV and AIDS for Africa alone in their 2014 budgets. Laudable as these efforts are, the availability of commodities alone is not sufficient to improve the overall impact on communities and livelihoods. Accessibility to quality-assured essential medicines needs to be tied to functional pharmaceutical supply chain management systems. Functional pharmaceutical supply management systems enable efficient procurement, distribution, and rational use of life-saving medicines.

  6. Can fuel services supply be secured? Building trust in a multi-lateral approach to nuclear fuel cycles

    International Nuclear Information System (INIS)

    Global climate change and concerns about energy supply security fuelling the nuclear desires of an increasing number of states, there is growing interest within the nonproliferation community to promote the establishment of an international system for the provision of nuclear fuel cycle services that would be 'equitable and accessible to all users of nuclear energy' (Rauf, 2008) while reducing proliferation risks. Although the idea was already voiced on the cradle of civilian use of nuclear energy (Baruch, 1946), the IAEA director's 2003 call for a group of international experts to examine the issue (ElBaradei, 2003) triggered renewed interest that resulted in up to twelve different proposals for multilateral nuclear fuel cycle arrangements (Rauf, 2008; Simpson, 2008). Nonproliferation experts have examined the conditions under which equitable and accessible access to enrichment, reprocessing and spent fuel disposal services can be granted to all users (Rauf, 2008; Braun 2006; Pellaud and al 2005). They suggested putting together multilateral nuclear approaches (MNA) that could consist in the establishment of mechanisms to assure fuel cycle services, or the shared ownership by recipient and host countries of fuel services facilities through either the creation of new multilateral centers or the conversion of existing national facilities into multinational enterprises. While countries that possess nuclear fuel facilities would benefit from the increased global security and strengthened non-proliferation situation that would result from the establishment of these MNAs, they would also be baited into participating by possible attraction of foreign investments as well as the opportunity to export high value services (Rushkin, 2006). Yet, what incentives would there be for a recipient non-nuclear state to participate in an arrangement that would intrinsically strip it of its sovereign right to ensure its fuel supply security? In addition to the economic benefits of

    Full Text Available The present study contributes to identifying obstacles to the development of a local biodiesel agro-industrial system (AGS in the state of Minas Gerais, Brazil. The research questions are: “How do local social characteristics influence the organizational effectiveness of agents involved in the joint production effort?”; and “How can the institutional arrangement of biodiesel production be described?” The method adopted is the case study, focused on family farmers served by the Family Farmers Rural Extension and Technical Assistance Company (EMATER. This state organization introduced castor beans (Ricinus communis L. to family farmers as an alternative crop to supply a processing plant (Darcy Ribeiro Biodiesel Plant—DRBP in northern Minas Gerais state, Brazil. These family farmers are not horizontally organized, and sign individual contracts with DRBP. The paper concludes that the primary obstacle to developing the biodiesel AGS with castor beans in Minas Gerais is the lack of horizontal organization among family farmers.

    The new energy saving windows with heat-reflecting shields have been developed, and for their practical use they need to be integrated into the automated system for controlling heat supply in buildings and the efficiency of their use together with the existing energy-saving measures must be determined. The study was based on the results of field tests of windows with heat-reflective shields in a certified climate chamber. The method to determine the minimum indoor air temperature under standby heating using heat-reflective shields in the windows and multifunctional energy-efficient shutter with solar battery have been developed. Annual energy saving for the conditions of different regions of Russia and France was determined. Using windows with heat-reflecting screens and a solar battery results in a triple power effect: reduced heat losses during the heating season due to increased window resistance; lower cost of heating buildings due to lowering of indoor ambient temperature; also electric power generation.

  9. Modeling and optimization of a hybrid system for the energy supply of a “Green” building

    International Nuclear Information System (INIS)

    Highlights: ► The system model is embedded in a dynamic decision model. ► The model has been applied to a specific case study. ► Optimal results are reported for two main cases: the presence/absence of the energy storage system. - Abstract: Renewable energy sources (RES) are an “indigenous” environmental option, economically competitive with conventional power generation where good wind and solar resources are available. Hybrid systems can help in improving the economic and environmental sustainability of renewable energy systems to fulfill the energy demand. The aim of this paper is to present a dynamic model able to integrate different RES and one storage device to feed a “Green” building for its thermal and electrical energy needs in a sustainable way. The system model is embedded in a dynamic decision model and is used to optimize a quite complex hybrid system connected to the grid which can exploit different renewable energy sources. A Model Predictive Control (MPC) is adopted to find the optimal solution. The optimization model has been applied to a case study where electric energy is also used to pump water for domestic use. Optimal results are reported for two main cases: the presence/absence of the energy storage system.

  10. Pressurized air supply device

    International Nuclear Information System (INIS)

    Ventilation air-conditioning facilities in a nuclear reactor building are adapted to suck clean external air not containing radioactivity through air supply filters disposed at an air intake port of the nuclear reactor building by means of an air supply blower and then supply the sucked air through an air supply duct and an air supply port to the inside of the power plant. Futher, pipeways for supplying sucked air to a compressor is branched from the air supply duct, through which air is supplied to an air compressor for instrumentation and an air compressor used in the power plant. The air sucked and compressed in the air compressor for instrumentation is further supplied by way of pipeways for supplying air for instrumentation to air-actuated valves, instruments, etc. Further, air sucked and compressed in the air compressor used in the power plant is further supplied by way of air supply pipeways for the power plant to a reservoir, air mask, etc. By supplying clean compressed air in this way, operators exposure dose can be reduced.

  11. Build-ups in the supply chain of the brain: on the neuroenergetic cause of obesity and type 2 diabetes mellitus

    Directory of Open Access Journals (Sweden)

    Achim Peters

    2009-04-01

    Full Text Available Obesity and type 2 diabetes have become the major health problems in many industrialized countries. A few theoretical frameworks have been set up to derive the possible determinative cause of obesity. One concept views that food availability determines food intake, i.e. that obesity is the result of an external energy “push” into the body. Another one views that the energy milieu within the human organism determines food intake, i.e. that obesity is due to an excessive “pull” from inside the organism. Here we present the unconventional concept that a healthy organism is maintained by a „competent brain-pull“ which serves systemic homeostasis, and that the underlying cause of obesity is “incompetent brain-pull”, i.e. that the brain is unable to properly demand glucose from the body. We describe the energy fluxes from the environment, through the body, towards the brain with a mathematical “supply chain” model and test whether its predictions fit medical and experimental data sets from our and other research groups. In this way, we show data-based support of our hypothesis, which states that under conditions of food abundance incompetent brain-pull will lead to build-ups in the supply chain culminating in obesity and type 2 diabetes. In the same way, we demonstrate support of the related hypothesis, which states that under conditions of food deprivation a competent brain-pull mechanism is indispensable for the continuance of the brain´s high energy level. In conclusion, we took the viewpoint of integrative physiology and provided evidence for the necessity of brain-pull mechanisms for the benefit of health. Along these lines, our work supports recent molecular findings from the field of neuroenergetics and continues the work on the “Selfish Brain” theory dealing with the maintenance of the cerebral and peripheral energy homeostasis.

  12. Some potential material supply constraints in solar systems for heating and cooling of buildings and process heat. (A preliminary screening to identify critical materials)

    Energy Technology Data Exchange (ETDEWEB)

    Watts, R.L.; Gurwell, W.E.; Nelson, T.A.; Smith, S.A.

    1979-06-01

    Nine Solar Heating and Cooling of Buildings (SHACOB) designs and three Agricultural and Industrial Process Heat (AIPH) designs have been studied to identify potential future material constraints to their large scale installation and use. The nine SHACOB and three AIPH systems were screened and found to be free of serious future material constraints. The screening was carried out for each individual system design assuming 500 million m/sup 2/ of collector area installed by the year 2000. Also, two mixed design scenarios, containing equal portions of each system design, were screened. To keep these scenarios in perspective, note that a billion m/sup 2/ containing a mixture of the nine SHACOB designs will yield an annual solar contribution of about 1.3 Quads or will displace about 4.2 Quads of fossil fuel used to generate electricity. For AIPH a billion square meters of the mixed designs will yield about 2.8 Quads/year. Three materials were identified that could possibly restrain the deployment of solar systems in the specific scenarios investigated. They are iron and steel, soda lime glass and polyvinyl fluoride. All three of these materials are bulk materials. No raw material supply constraints were found.

  19. Energy transition and security: which voluntary codes? Energy efficiency: IEA, IEC and ISO dialogue. The European Commission's safety, solidarity and efficiency measures. Securing natural gas supplies and favoring cogeneration. Less energy consuming buildings: rework of the energy efficiency directive. Energy efficiency inside buildings: GDF Suez report

    International Nuclear Information System (INIS)

    This dossier gathers a series of short articles about energy security and efficiency in a context of policy transition. The first paper deals with the use of international standards to promote energy efficiency thanks to efficient public policies and private sector actions. This was the main topic of the mixed workshop organized by the International electrotechnics Commission (IEC) in spring 2009. The second paper presents the new strategic analysis of the European commission in the domain of energy which stresses on the '20-20-20' climate change proposals approved in December 2008. A new European action plan for energy security and solidarity defines 5 domains requiring an extra action to warrant a sustainable energy supply. The commission is also examining the challenges that Europe will have to face between 2020 and 2050. The third article treats of the security of natural gas supplies which represents a quarter of the European Union (EU) energy mix. The supply crises susceptible to occur may have serious economic and social consequences. Therefore, the EU must be prepared to warrant its security of supplies. Cogeneration allows the EU to stay close to its energy goals. Buildings play a key role in the realisation of the EU's energy saving objectives and fight against climate change. The new directive on buildings energy efficiency (2002/91/CE) will allow to exploit this potential of saving and to stimulate sustainable investment and employment as well. Finally, the publication of the second WBCSD (World business council for sustainable development) international report on buildings energy efficiency has led GDF Suez utility to reaffirm its commitment in favour of energy saving and efficiency.

    More and more local authorities in the Netherlands are aiming for climate or energy neutrality. Within the municipal borders, a balance needs to be found between sustainable energy generation and the energy use of dwellings, offices, businesses and vehicles. Practice is more unruly, however, particularly in existing dwellings, offices and businesses. Heat supply, particularly in combination with green heat, offers opportunities [Dutch] Steeds meer gemeenten streven naar klimaat- of energieneutraliteit. Binnen de gemeentegrenzen moet er evenwicht komen tussen de opwekking van duurzame energie en het energiegebruik van woningen, kantoren, bedrijven en voertuigen.

  1. Energy supply for buildings with focus on solar power in the urban context - an interactive WebGIS implementation for citizens

    Science.gov (United States)

    Castellazzi, Bernhard; Biberacher, Markus

    2016-04-01

    Many European cities nowadays offer their citizens Web-GIS applications to access data about solar potentials for specific buildings. However, the actual benefit of such solar systems can only be investigated, if their generation is not considered singularly, but in combination with information about temporal appearance of energy demand (heat, electricity), type of primary heating system, hourly internal consumption of photovoltaic power, feed-in power and other important financial and ecological aspects. Hence, the presented application addresses citizens, who are interested in the integration of solar power in buildings and would like to have an extended view on related impacts. Based on user inputs on building parameters and energy use, as well as high spatial and temporal resolved solar data for individual roof areas, financial and ecological effects of solar thermal installations and PV are estimated. Also interactions between heat and power generation are considered in the implemented approach. The tool was developed within the Central Europe project „Cities on Power" and is being realized for the cities Torino, Warsaw, Dresden, Klagenfurt and Ravenna.

  3. NGL supply

    International Nuclear Information System (INIS)

    Highlights of the key drivers behind natural gas liquids (NGL) supply were discussed. These include: (1) volume and location of conventional oil and gas reserves, (2) accessibility of gas to reach economic natural gas markets in North America, (3) composition of produced gas stream, and (4) access to economic NGL logistics and processing infrastructure. Supply developments over the last 10 years and the supply outlook were also reviewed. The review showed that the value of Canadian NGL production has risen steadily over the last 10 years with a sharp increase in 1996. There has been continued expansion of NGTL, TCPL and PGT gas infrastructures. NGL supply is driven by natural gas production. Extraction of NGLs from gas is dependent on demand, economics and infrastructure. It was considered very likely that future NGL supply will increase with increased gas production and recovery from upgraders. 5 figs

    The Xingo Program is a multidisciplinary initiative, developed jointly by the CNPq-Brazilian National Council for Scientific and Technological Development and CHESF- Hydroelectric Power Company of the Sao Francisco River. Its main objective is to promote the development of a semi-arid region through actions undertaken in different areas; more specifically, to seek energetic solutions on suitable techniques in the region and at the same time identify local demands and business opportunities that may lead to the introduction of enterprises in the region, principally focusing social and citizenship development. Eight rural communities located in the perimeter of Xingo program were selected for implementing the first pilot projects. This paper describes a technical and social diagnosis, and a conceptual project that were made for each community, considering the resources and the local available potentialities, prioritizing energy supply to schools, health centers and the supply of drinking water. In particular, the case study describes the process of energy supply to Guatle community, an old farm without any education/health infrastructure and water is supplied by means of trucks, in which there was a significant increase in the number of families after being occupied by activists of the Landless movement. In this community a school unit was built and electrified (school and park illuminated, TV, refrigerator), a 12 m{sup 3}/day water supply system was installed in and old and abandoned well, the water of which showed an excellent quality and quantity, 6 m{sup 3}/h, a very rare occurrence in that region. Later, literacy courses were given to young people and adults, the natural aptitude of the inhabitants. With the arrival of water, the first conflicts for the management of these resources emerged. The experience in Gualte, in spite of the successes and failures, could be considered as a lesson that should be learned. The feeling of citizenship of the needy community

  7. Water supply

    International Nuclear Information System (INIS)

    Options and methodologies for the development of fresh water supplies on Bikini Atoll are much the same as those practiced in the rest of the Marshall Islands and for that matter, most atolls in the central Pacific Ocean Basin. That is, rainfall distribution on Bikini produces a distinct wet season, lasting from about May through November, with the remaining months being generally dry. As a result, fresh water from surface catchments tends to be plentiful during the wet season? but is usually scarce during the dry months, and alternative sources such as groundwater must be utilized during this time. On Bikini the problems of fresh water supply are somewhat more difficult than for most Marshall Island atolls because rainfall is only about half the Marshall Island's average. Tus water supply is a critical factor limiting the carrying capacity of Bikini Atoll. To address this problem BARC has undertaken a study of the Bikini Atoll water supply. Te primary objectives of this work are to determine: (1) alternatives available for fresh water supply, 2 the amounts, location and quality of available supplies and 3 optimal development methods. The study planned for one's year duration, has been underway only since the summer of 1985 and is thus not yet fully completed. However, work done to date, which is presented in this report of preliminary findings, provides a reasonably accurate picture of Bikini's fresh water supplies and the various options available for their development. The work remaining to be completed will mainly add refinements to the water supply picture presented in the sections to follow

  15. Sustainable Buildings in Interaction

    DEFF Research Database (Denmark)

    Elle, Morten

    The first attempts to build sustainable buildings in Denmark were typically located on the countryside. The basic idea was to create buildings that were independent of the technical infrastructure. District heating has, however, been the dominating solution to heating in buildings in Denmark, and...... the focus on sustainable building have gradually turned from special houses on the countryside to normally looking houses in the urban fabric, integrated in the technical infrastructure. Some new built urban areas in Denmark will, however, not have to be supplied with district heating – these...... developments are going to consist of passive houses. The first sustainable buildings were built by their users, and the user – building interaction still play a decisive role for the performance of the present sustainable buildings. The users have to understand how the building functions. Urban design is...

    International Nuclear Information System (INIS)

    Recently, a study investigated the feasibility of building a large 60 GeV, kaon factory accelerator. This paper presents the conceptual design of the magnet power supplies and energy storage system. In this study the following three systems were investigated: (a) power supply using storage generator; (b) power supply using inductive storage device; and (c) resonant power supplies. These systems were analyzed from both technical and economical points of view. It was found that all three systems are feasible and can be built using commercially available components. From a technical point of view, the system using inductive storage is the most advantageous. The resonant power supply is the most economical solution

  19. Gas supplies

    International Nuclear Information System (INIS)

    Of all the main sources of fossil fuels, natural gas stands as a newcomer. While it has already reached an age of maturity in the New World, due to the seniority of its development there, it is marked by the hopes and growth rates of a new energy source in European and Asia. As it becomes a major world energy source, natural gas has to secure consumer confidence, and thereby its own future development. To do so, a reliable supply of it must remain available, and at prices compatible with users' needs. How does natural gas resemble other sources of energy. And what specific features distinguish it in many ways from the others. The answers to these questions are themselves basis elements for understanding the physical process linking the gas field to the client's appliance. They also shed some light on the evolving commercial ties among producers and gas companies on the large regional markets around the world - North America, Europe and the Far East

    Full Text Available Significant reductions of heat demand, low-carbon and renewable energy sources, and district heating are key elements in 100% renewable energy systems. Appraisal of district heating along with energy efficient buildings and individual heat supply requires a geographical representation of heat demand, energy efficiency and energy supply. The present paper describes a Heat Atlas built around a spatial database using geographical information systems (GIS. The present atlas allows for per-building calculations of potentials and costs of energy savings, connectivity to existing district heat, and current heat supply and demand. For the entire building mass a conclusive link is established between the built environment and its heat supply. The expansion of district heating; the interconnection of distributed district heating systems; or the question whether to invest in ultra-efficient buildings with individual supply, or in collective heating using renewable energy for heating the current building stock, can be based on improved data.

  13. THE COSTS OF ENERGY SUPPLY SECURITY

    Rogner, H.H.; Langlois, L.M.; McDonald, A.; Weisser, D.; Howells, M.

    2007-07-01

    In general, increasing a country's energy supply security does not come for free. It costs money to build up a strategic reserve, to increase supply diversity or even to accelerate energy efficiency improvements. Nor are all investments in increasing energy supply security cost effective, even if the shocks they are designed to insure against can be predicted with 100% accuracy. The first half of the paper surveys different definitions and strategies associated with the concept of energy supply security, and compares current initiatives to establish an 'assured supply of nuclear fuel' to the International Energy Agency's (IEA's) system of strategic national oil reserves. The second half of the paper presents results from several case studies of the costs and effectiveness of selected energy supply security policies. One case study examines alternative strategies for Lithuania following the scheduled closure of the Ignalina-2 nuclear reactor in 2009. The second case study examines, for countries with different energy resources and demand structures, the effectiveness of a policy to increase supply diversity by expanding renewable energy supplies.

Companies use different strategies to reduce uncertainty, like building agile supply chains, increasing resilience, postponement, etc. All these strategies require strong supply chain collaboration. Although research interest in supply chain collaboration is growing, no research has been done in Albania. This paper is one of the first to investigate supply chain management practices and the extent of supply chain collaboration in the Albanian beer industry. The aim of this research is twofold: first, to investigate how supply chain uncertainty influences the extent of collaboration with the supply chain members, and second, to analyze how organizational culture facilitates the collaboration process. Semi-structured interviews were conducted with the managers of the main beer companies. A guide questionnaire was prepared. It consisted of open and rate-scale questions about supply chain collaboration, supply chain uncertainty, supply chain management practices and organizational culture. The research will show that a high level of supply chain uncertainty does not always lead to a high degree of collaboration with the supply chain members. Organizational culture is the key driver of a successful collaboration. Not all types of culture can facilitate collaboration but only the ones with an external orientation.

  2. PV supply chain growing pains

    International Nuclear Information System (INIS)

    This article discussed issues involving the supply chain for photovoltaic (PV) equipment that is emerging in Ontario as a result of the Feed-in-Tariff (FIT) program that was launched in late 2009. The rapidly developing PV supply chain may not be taking a sustainable path. The domestic-content requirement is making manufacturers outlay capital to set up manufacturing in Ontario without reliable market data. Only a small number of dealer/installers have any meaningful experience designing and installing grid-tie PV. Until recently, wholesale distributors designed and supplied most grid-tie PV systems in Canada, and solar dealers/installers or electricians or electrical contractors did the installation. Instead of selling directly to dealer/installers, solar manufacturers should develop strong relationships with wholesalers, who have system design experience and product training. This would allow manufacturers to focus on their core strength, reach more customers, and keep lower inventory levels. Wholesale distributors in turn provide dealer/installers with expertise in product and system design, training from a range of manufacturers, marketing and logistics support, and immediate access to inventory. Manufacturers generally lack appropriate accounting, engineering, marketing, and logistics services to deal with a multitude of active accounts, and they are not structured to work with architects and engineers to do complete system design. Partnering with wholesale distributors allows manufacturers to take on the residential and small-scale commercial sectors by building brand awareness and increasing market share and sales across Canada. 2 figs.

  3. European oil product supply modelling

    International Nuclear Information System (INIS)

    Over the last few years, trends in European oil product consumption (in terms of level as structure and quality) has important implications of the refining industry. In this context, the purpose of this thesis consists in building a mathematical programming model applied to the European refineries in order to determine oil product supply prices, European refining industry investments and oil product exchanges of the European Union. The first part presents the reason for our choice for a long-term aggregate multi-refineries linear programming model, based on European refineries characteristics and the objectives of our model. Its dual properties are studied in detail and we focus particularly on the European exchange modelling. In the second part, an analysis of the European refining trends leads us to identify parameters and variables of the model that are essential to the aggregate representation of the European oil product supply. The third part is devoted to the use of this model, regarding two scenarios of increasingly stringent specifications for gasoline and diesel oil. Our interest for these products is due to their important share of the European oil product consumption and the not insignificant responsibility of the transport sector for atmospheric pollution. Finally, in order to have the use of an overall picture of the European refining industry, we build a regression model summarizing, though a few equations, the main relations between the major endogenous and exogenous variables o the LP model. Based on pseudo-data, this kind of model provides a simple and robust representation of the oil product supply. But a more specialized analysis of the refining industry operations, turning on a technical assessment of processing units, is reliant on the use of an optimization model such as the model we have built.

    Full Text Available Background: Today it is virtually impossible to operate alone on the international level in the logistics business. This promotes the establishment and development of new integrated business entities - logistic operators. However, such cooperation within a supply chain creates also many problems related to the supply chain reliability as well as the optimization of the supplies planning. The aim of this paper was to develop and formulate the mathematical model and algorithms to find the optimum plan of supplies by using economic criterion and the model for the probability evaluating of non-failure operation of supply chain. Methods: The mathematical model and algorithms to find the optimum plan of supplies were developed and formulated by using economic criterion and the model for the probability evaluating of non-failure operation of supply chain. Results and conclusions: The problem of ensuring failure-free performance of goods supply channel analyzed in the paper is characteristic of distributed network systems that make active use of business process outsourcing technologies. The complex planning problem occurring in such systems that requires taking into account the consumer's requirements for failure-free performance in terms of supply volumes and correctness can be reduced to a relatively simple linear programming problem through logical analysis of the structures. The sequence of the operations, which should be taken into account during the process of the supply planning with the supplier's functional reliability, was presented.

  19. Energy-efficient and cost-effective in-house substations bypass for improving thermal and DHW (domestic hot water) comfort in bathrooms in low-energy buildings supplied by low-temperature district heating

    DEFF Research Database (Denmark)

    Brand, Marek; Dalla Rosa, Alessandro; Svendsen, Svend

    2014-01-01

    Using a bypass to redirect a small flow through the in-house DH (district heating) substation directly to the return pipe is a commonly used but energy-inefficient solution to keep the DH network “warm” during non-heating seasons. Instead, this water can be redirected to the bathroom FH (floor...... heating) to cool down further and thus reduce the heat lost from bypass operation while tempering the bathroom floor and guaranteeing fast provision of DHW (domestic hot water). We used the commercial software IDA-ICE to model a reference building where we implemented various solutions for controlling the...... redirected bypass flow and evaluated their performance. The effect on the DH network was investigated using Termis software. Bypass flow redirected into bathroom FH during the non-heating period resulted in comparison to the reference case on average in a 0.6 °C–2.2 °C increase of the floor surface...

    International Nuclear Information System (INIS)

    The whole reactor building is accommodated in a shaft and is sealed level with the earth's surface by a building ceiling, which provides protection against penetration due to external effects. The building ceiling is supported on walls of the reactor building, which line the shaft and transfer the vertical components of forces to the foundations. The thickness of the walls is designed to withstand horizontal pressure waves in the floor. The building ceiling has an opening above the reactor, which must be closed by cover plates. Operating equipment for the reactor can be situated above the building ceiling. (orig./HP)

    This dossier gathers a series of short articles about energy security and efficiency in a context of policy transition. The first paper deals with the use of international standards to promote energy efficiency thanks to efficient public policies and private sector actions. This was the main topic of the mixed workshop organized by the International electrotechnics Commission (IEC) in spring 2009. The second paper presents the new strategic analysis of the European commission in the domain of energy which stresses on the '20-20-20' climate change proposals approved in December 2008. A new European action plan for energy security and solidarity defines 5 domains requiring an extra action to warrant a sustainable energy supply. The commission is also examining the challenges that Europe will have to face between 2020 and 2050. The third article treats of the security of natural gas supplies which represents a quarter of the European Union (EU) energy mix. The supply crises susceptible to occur may have serious economic and social consequences. Therefore, the EU must be prepared to warrant its security of supplies. Cogeneration allows the EU to stay close to its energy goals. Buildings play a key role in the realisation of the EU's energy saving objectives and fight against climate change. The new directive on buildings energy efficiency (2002/91/CE) will allow to exploit this potential of saving and to stimulate sustainable investment and employment as well. Finally, the publication of the second WBCSD (World business council for sustainable development) international report on buildings energy efficiency has led GDF Suez utility to reaffirm its commitment in favour of energy saving and efficiency.

  9. Control of supply temperature

    Energy Technology Data Exchange (ETDEWEB)

    Madsen, H.; Nielsen, T.S.; Soegaard, H.T.

    1996-09-01

    For many district heating systems, e.g. the system in Hoeje Taastrup, it is desirable to minimize the supply temperature from the heat production unit(s). Lower supply temperature implies lower costs in connection with the production and distribution of heat. Factors having impact on the heat demand are for instance solar radiation, wind speed, wind direction and a climate independent part, which is a function of the time of the day/week/year. By applying an optimization strategy, which minimizes the supply temperature, it is assumed that optimal economical operation can be obtained by minimizing the supply temperature and thereby the heat losses in the system. The models and methods described in this report take such aspects into account, and can therefore be used as elements in a more efficient minimization of the supply temperature. The theoretical part of this report describes models and methods for optimal on-line control of the supply temperature in district heating systems. Some of the models and methods have been implemented - or are going to be implemented - in the computer program PRESS which is a tool for optimal control of supply temperature and forecasting of heat demand in district heating systems. The principles for using transfer function models are briefly described. The ordinary generalized predictive control (OGPC) method is reviewed, and several extensions of this method are suggested. New controller, which is called the extended generalized predictive controller (XGPC), is described. (EG) 57 refs.

  11. KEKB electromagnet power supply

    International Nuclear Information System (INIS)

    Numbers of electromagnet power supply for KEKB are 2,243 except BT. To satisfy stability, DAC in the current control circuit, current detector, R and D of small thermostatic bath and a calibration method of current using CPU were introduced. They satisfied needs. With producing R and D apparatus of switching source, problems of ripple, stability and noise were solved, so that we began mass production. In this paper, many kinds of R and D and performance and troubles after operation of KEKB power source are described. A plan of design of power supply consisted of seven items such as high accuracy, serial communication of interface, small type, high affectivity, easy maintenance, independence of current setting and current detector for monitor and control of radiation and conduction noise of switching power supply. These items were satisfied by development of interface board of ARCNET communication, introduction of double buffer method for interface through CPU, power supply unit by air-cooled method using a switching method and small thermostatic oven for bending and quadrupole electromagnet. R and D of DCCT, burden and shunt resistance, DAC, thermostatic bath, power supply, offset and gain calibration by double buffer method, specification of power supply, various kinds of measurements of mass production apparatus at rising, after long operation and problems before and after operation are reported. The results of R and D made satisfy the specification of stability and ripple of power supply. Although many switching power supply were operated, there was no noise and troubles at the initial period decreased. However, in order to use many power supply, the performance measurement and maintenance are very important at long shut down. (S.Y.)

In this first rich illustrated volume the results of the design studies illustrating passive solar architecture in buildings in the European Community are presented in particular for the building categories as mentioned in the subtitle. In a second volume, a similar series of studies is presented for the building categories: office buildings, public buildings and hotels and holiday complexes. Several Design Support Workshops were organized during the Building 2000 programme during which Building 2000 design teams could directly exchange ideas with the various design advice experts represented at these workshops. In the second part of the Building 2000 final report a summary of a selection of many reports is presented (15 papers), as produced by Design Support experts. Most of the design support activities resulted in changes of the various designs, as have been reported by the design teams in the brochures presented in the first part of this book. It is to be expected that design aids and simulation tools for passive solar options, daylighting concepts, comfort criteria etc., will be utilized more frequently in the future. This will result in a better exchange of information between the actual design practitioners and the European R and D community. This technology transfer will result in buildings with a higher quality with respect to energy and environmental issues

  18. Foreign uranium supply

    International Nuclear Information System (INIS)

    Known foreign uranium resources are concentrated in a few countries. The resources of many countries are largely unassessed, but the known uranium countries appear to have the best potential for future expansion. Availability of supply from known resources will depend on resolution of national policies regarding uranium production, ownership and export, and actions of the mining industry. Foreign uranium demand projections have decreased markedly in the last few years, and currently planned and attainable production should be adequate through the 1980's. Longer term resources and supply outlook are still a major concern to both those planning electric supply systems based on converter reactors and those considering reprocessing and recycle of uranium and plutonium and development of breeder reactors. Work continues to clarify long-term supply in several countries and internationally, but more effort, and time, will be needed to clarify these issues

    Full Text Available Background: Supply chain risk management increasingly gains prominence in many international industries. In order to strengthen supply chain structures, processes, and networks, adequate potentials for risk management need to be built (focus on effective logistics and to be utilized (focus on efficient logistics. Natural-based disasters, such as the case of Fukushima, illustrate how crucial risk management is. Method: By aligning a theoretical-conceptual framework with empirical-inductive findings, it may be hypothesized that logistical systems do have a positive effect on supply chain risk management activities.  Result/conclusion:  Flexibility and capacity, as well as redundancy and standardization, are often viewed as being conflictionary. It shows, however, that in the light of supply chain risk management, those factors may yield a common benefit if proper logistics systems are applied.

  5. SIMULATING THE SUPPLY DISRUPTION FOR THE COORDINATED SUPPLY CHAIN

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    There are many disruptive accidents in the supply chain operations system and achieving the coordination of supply chain is main objective for supply chain research. While disruptive accidents have increasingly influenced the coordinated operation of the supply chain, existing research literature on the supply chain coordination is setting in a stationary environment. The answer for how the disruptive accidents affect the coordinated supply chain is given in this paper. Based on the benchmark supply chain which is coordinated by the negative incentive mechanism, we study the impacts of supply disruption on the supply chain system by using simulation approach in which two different distribution function of random variable are used to express the supply disruption. Comparison between these two simulation results and possible coordination mechanism under the supply disruption are proposed. From the perspective of supply chain risk management, we provide the inspiration for the manager.

  11. Compliance with building energy regulations for new-build dwellings

    International Nuclear Information System (INIS)

    Despite increasingly stringent building energy regulations worldwide, non-compliance exists in practice. This paper examines the profile of compliance with building energy regulations for new-build dwellings. In total 404 new-build dwellings completed in the UK from 2006 to 2009 were investigated. Only a third of these dwellings were evidenced as being compliant with Building Regulations Part L (England and Wales). Such low compliance casts a serious concern over the achievability of the UK Government's target for all new-build homes to be ‘zero carbon’ from 2016. Clearly evidenced was a lack of knowledge of Part L and its compliance requirements among the supply and building control sides of new-build dwellings. The results also indicate that the compliance profile was influenced by factors including Standard Assessment Procedure (UK Government's methodology for energy efficiency) calculation submissions, learning and experience of builders and building controls with Part L, use of Part L1A checklist, the introduction of energy performance certificate (EPC), build method, dwelling type, and project size. Better compliance was associated with flats over houses and timber frame over masonry. The use of EPC and Part L1A checklist should be encouraged. Key to addressing the lack of compliance with building energy regulations is training. -- Highlights: ► There exists a lack of compliance, worldwide, with building energy regulations. ► The implementation of England and Wales building energy regulations is problematic. ► Training, learning and experience of builders and building control are critical. ► Energy performance certificate and Part L 2006 checklist helped achieve compliance. ► Flats achieved better compliance over houses; and timber frame over masonry.

  12. Understanding the supply chain

    Directory of Open Access Journals (Sweden)

    Aćimović Slobodan

    2006-01-01

    Full Text Available Supply chain management represents new business philosophy and includes strategically positioned and much wider scope of activity in comparison with its "older brother" - management of logistics. Philosophy of the concept of supply chain is directed to more coordination of key business functions of every link in distribution chain in the process of organization of the flow of both goods and information, while logistic managing instruments are focused on internal optimum of flows of goods and information within one company. Applying the concept of integrated supply chain among several companies makes the importance of operative logistics activity even greater on the level of one company, thus advancing processes of optimum and coordination within and between different companies and confirms the importance of logistics performances for the company’s profitability. Besides the fact that the borders between companies are being deleted, this concept of supply chain in one distribution channel influences increasing of importance of functional, i.e. traditional business managing approaches but instead it points out the importance of process managing approaches. Although the author is aware that "there is nothing harder, more dangerous and with uncertain success, but to find a way for introducing some novelties (Machiavelli, it would be even his additional stimulation for trying to bring closer the concept and goals of supply chain implementation that are identified in key, relevant, modern, theoretical and consulting approaches in order to achieve better understanding of the subject and faster implementation of the concept of supply chain management by domestic companies.

In this second rich illustrated volume the results of the design studies illustrating passive solar architecture in buildings in the European Community are presented in particular for the building categories as mentioned in the subtitle. In the first volume, a similar series of studies is presented for the building categories: schools, laboratories and universities, and sports and educational centres. Several Design Support Workshops were organized during the Building 2000 programme during which Building 2000 design teams could directly exchange ideas with the various design advice experts represented at these workshops. In the second part of the Building 2000 final report a summary of a selection of many reports is presented (11 papers), as produced by Design Support experts. Most of the design support activities resulted in changes of the various designs, as have been reported by the design teams in the brochures presented in the first part of this book. It is to be expected that design aids and simulation tools for passive solar options, daylighting concepts, comfort criteria etc., will be utilized more frequently in the future. This will result in a better exchange of information between the actual design practitioners and the European R and D community. This technology transfer will result in buildings with a higher quality with respect to energy and environmental issues

    2012-10-01

    Full Text Available In recent years, there are several methods introduced for the improvement of operational performances. Total quality management and supply chain management are two methods recommended for this purpose. These two approaches have been studied in most researches separately, while they have objectives in common, and this makes them a strategic means, which can be used, simultaneously. Total quality management and supply chain management play significant roles to increase the organizational competitiveness power. Moreover, they have only one purpose that is customer satisfaction, and they are different only on their approaches to reach their objectives. In this research, we aim to study both approaches of quality management and supply chain, their positive increasing effects that may be generated after their integration. For this purpose, the concept and definitions of each approach is studied, independently, their similarities and differences are recognized, and finally, the advantages of their integration are introduced.

  3. Fuel supply security

    International Nuclear Information System (INIS)

    Stable fuel supply is a prerequisite for any nuclear power program including ISER-PIUS. It encompasses procurement of uranium ore, enriched uranium and fuel elements. Uranium is different from oil in that it can be stockpiled for more than a decade besides the fact that the core residence time is as long as six years, for example in the case of ISER-PIUS. These basic fuel characteristics are favoring nuclear fuel over others in terms of supply security. The central concern will be a gradual increase in prices of uranium and enrichment. Under the present glut situation with the worldwide prevalence of LWRs, fuel supply security seems ensured for the time being till the middle of 21st century. It is estimated that by the turn of the century, the free world will have roughly 450 GWe capacity of nuclear power. If 10 % is supplied for ISER-PIUS, more than 200 modules of 200 MWe ISER-PIUS may be deployed all over the world probably starting around 2000. As part of the fuel supply security consideration, heavy water reactor (HWR) may seem interesting to such a country as Indonesia where there is uranium resources but no enrichment capability. But it needs heavy water instead and the operation is not so easy as of LWR, because of the positive void coefficient as was seen at the Chernobyl-4. Safeguarding of the fuel is also difficult, because it lends itself to on line refueling. The current and future situation of the fuel supply security for LWR seem well founded and established long into the future. (Nogami, K.)

    2006-01-01

    We investigate the relationship between GP supply and body mass index (BMI) in England. Individual level BMI is regressed against area whole time equivalent GPs per 1,000 population plus individual and area level covariates. Using IV models we find that a 10% increase in GP supply is associated with a mean reduction in BMI of around 1 kg/m2 (around 4% of mean BMI). Our study suggests that better primary care in the form of reduced list sizes per GP can improve the management of obesity.

    Comfortable relationships are a prerequisite in a building in order to fulfill its purpose. This requires a supply of energy resources and a supply engineering. Due to the price increases of fossil fuels and due to the connection between CO2 emissions and climate change, these systems come into the focus of conservation efforts. The work package 4 of the project 'Low Energy Living' covers the heating engineering or the supply of building's heating, respectively. Possibilities have to be found to reduce CO{sub 2} emissions and to enable a continuous economic plant operation. The contribution under consideration reports on the application of composite joint projects in existing buildings. This requires a networking and an automation of the process chain with the aim of an inclusion of detailed information on acting factors and disturbances in the standard procedure.

    Full Text Available Construction projects are conventionally analyzed considering factors such as cost and completion time. The present paper focuses on the projects particularly dealing with the house or building. The paper aims at an objective of introducing a synergy between project and supply chain management. After a brief relevant literature review, major construction activities have been discussed and the associated synergy between project management and supply chain concepts has been explained. Applications of the supply chain concepts such as forward and reverse logistics along with the customer order decoupling point in the context of construction management are discussed as a result of the proposed development. For this purpose, a categorization of construction product is developed on the basis of land and building characteristics and it is the major contribution of the present paper. This is also expected to be useful for estimating lead time and availability of the product in the context of relevant supply chain, and an associated managerial implication.

    2016-03-01

    The 2008–2010 food crisis might have been a harbinger of fundamental climate-induced food crises with geopolitical implications. Heat-wave-induced yield losses in Russia and resulting export restrictions led to increases in market prices for wheat across the Middle East, likely contributing to the Arab Spring. With ongoing climate change, temperatures and temperature variability will rise, leading to higher uncertainty in yields for major nutritional crops. Here we investigate which countries are most vulnerable to teleconnected supply-shocks, i.e. where diets strongly rely on the import of wheat, maize, or rice, and where a large share of the population is living in poverty. We find that the Middle East is most sensitive to teleconnected supply shocks in wheat, Central America to supply shocks in maize, and Western Africa to supply shocks in rice. Weighing with poverty levels, Sub-Saharan Africa is most affected. Altogether, a simultaneous 10% reduction in exports of wheat, rice, and maize would reduce caloric intake of 55 million people living in poverty by about 5%. Export bans in major producing regions would put up to 200 million people below the poverty line at risk, 90% of which live in Sub-Saharan Africa. Our results suggest that a region-specific combination of national increases in agricultural productivity and diversification of trade partners and diets can effectively decrease future food security risks.

  9. Oil sands supply outlook

    International Nuclear Information System (INIS)

    In March 2004, The Canadian Energy Research Institute released a report on the expected future supply from Alberta's oil sands. The report indicates that the future for the already well-established oil sands industry is promising, particularly given the outlook for oil prices. The challenges facing the industry include higher industry supply costs and the need for innovative commercial and technological solutions to address the risks of irregularities and changes in crude oil prices. In 2003, the industry produced 874 thousand barrels per day of synthetic crude oil and unprocessed crude bitumen. This represents 35 per cent of Canada's total oil production. Current production capacity has increased to 1.0 million barrels per day (mbpd) due to new projects. This number may increase to 3.5 mbpd by 2017. Some new projects may be deferred due to the higher raw bitumen and synthetic crude oil supply costs. This presentation provided supply costs for a range of oil sands recovery technologies and production projections under various business scenarios. tabs., figs

  10. Exploration Supply Chain Simulation

    Science.gov (United States)

    2008-01-01

    The Exploration Supply Chain Simulation project was chartered by the NASA Exploration Systems Mission Directorate to develop a software tool, with proper data, to quantitatively analyze supply chains for future program planning. This tool is a discrete-event simulation that uses the basic supply chain concepts of planning, sourcing, making, delivering, and returning. This supply chain perspective is combined with other discrete or continuous simulation factors. Discrete resource events (such as launch or delivery reviews) are represented as organizational functional units. Continuous resources (such as civil service or contractor program functions) are defined as enabling functional units. Concepts of fixed and variable costs are included in the model to allow the discrete events to interact with cost calculations. The definition file is intrinsic to the model, but a blank start can be initiated at any time. The current definition file is an Orion Ares I crew launch vehicle. Parameters stretch from Kennedy Space Center across and into other program entities (Michaud Assembly Facility, Aliant Techsystems, Stennis Space Center, Johnson Space Center, etc.) though these will only gain detail as the file continues to evolve. The Orion Ares I file definition in the tool continues to evolve, and analysis from this tool is expected in 2008. This is the first application of such business-driven modeling to a NASA/government-- aerospace contractor endeavor.

  17. Study on the agile supply chain management based on agent

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The most important task of the agile supply chain management (ASCM) is to reconfigure a supply chain based on the customers' requirement. Without more sophisticated cooperation and dynamic formation in an agile supply chain, it cannot be achieved for mass customization, rapid response and high quality services. Because of its great potential in supporting cooperation for the supply chain management, agent technology can carry out the cooperative work by inter-operation across networked human, organization and machines at the abstractive level in a computational system. A major challenge in building such a system is to coordinate the behavior of individual agent or a group of agents to achieve the individual and shared goals of the participants. In this paper, the agent technology is used to support modeling and coordinating of supply chain management.

  19. The Path to a Reliable Supply of Medical Radioisotopes

    International Nuclear Information System (INIS)

    Medical imaging techniques using technetium-99m account for roughly 80% of all nuclear medicine procedures, representing over 30 million examinations worldwide every year. Disruptions in the supply chain of these medical isotopes - which have half-lives of 66 hours for molybdenum-99 (99Mo) and 6 hours for technetium-99m (99mTc), and thus must be produced continually - can lead to cancellations or delays in important medical testing services. Unfortunately, supply reliability has declined over the past decade, due to unexpected or extended shutdowns at the few ageing, 99Mo-producing, research reactors and processing facilities. These shutdowns have created global supply shortages. At the request of its member countries, the OECD Nuclear Energy Agency (NEA) established the High-level Group on the Security of Supply of Medical Radioisotopes (HLG-MR) in 2009. During its two-year mandate, the HLG-MR assessed the factors rendering the supply chain vulnerable and identified practical measures - near, medium and long term - to ensure the security of supply of this important medical isotope. Building on its findings and assessments, the HLG-MR developed a comprehensive policy approach to encourage long-term supply security of 99Mo/'99mTc, detailing the essential steps to be taken by governments, industry and the health community to address the vulnerabilities within the supply chain, including changing an economic structure that does not support or reinforce reliable supply

  20. Reactor building

    International Nuclear Information System (INIS)

    The present invention concerns a structure of ABWR-type reactor buildings, which can increase the capacity of a spent fuel storage area at a low cost and improved earthquake proofness. In the reactor building, the floor of a spent fuel pool is made flat, and a depth of the pool water satisfying requirement for shielding is ensured. In addition, a depth of pool water is also maintained for a equipment provisionally storing pool for storing spent fuels, and a capacity for a spent fuel storage area is increased by utilizing surplus space of the equipment provisionally storing pool. Since the flattened floor of the spent fuel pool is flushed with the floor of the equipment provisionally storing pool, transfer of horizontal loads applied to the building upon occurrence of earthquakes is made smooth, to improve earthquake proofness of the building.

  3. Power supply in future: ecological aspects

    International Nuclear Information System (INIS)

    The most important prerequisites for an ecological supply of energy in the future is the opting out of nuclear energy and the completion of the second and third phase of the socio-ecological tax reform. As a part of our energy will continue to be generated on the basis of fossil fuels in the foreseeable future, it is essential that a radical change takes place in the efficiency of fossil energy engineering. In addition to this, any possible energy-saving potential must be exploited; this includes the new energy-saving law, promoting the modernisation of old buildings and modern energy management (heat insulation, heating engineering, warm water heating etc.). For an ecological power supply the share of renewable energies must be increased to form a major pillar of our power supply. The '100,000-roof' programme of the German federal government and the development programme for near-market renewable energy sources form part of this approach. Energy research should shift its orientation and accelerate the conversion of our power supply: priority should be given to developing energy-saving technologies and renewable energy. Supporting municipalities and public utilities is especially important. This means revising the basic conditions of energy laws so that they assist public utilities to face competition as power utilities. (orig.)

    2011-07-01

    The report's main objective is to investigate employment within the power supply industry and the power supply related activities. The report will describe the composition of employees in regard to sex, age and education. The power supply industry is defined in Statistics Norway's Standard Industrial Classification, as 'Production and distribution of electricity'. The group of companies related to power supply related activities employ similar persons in regard to education and occupation, typical to companies in the power supply industry. In the report, these two groups make up the power supply sector. In 2010 there were 18215 employees in the power supply sector. This constitutes an increase of nearly 12 per cent since 2004 and 1,7 per cent since 2008. The sex distribution of about 80 per cent men and 20 per cent women has been fairly stable since 2004. Compared to the private sector in general the power supply sector has a low share of women among its employees. In 2009 the level of education in the power supply sector was higher than for the private sector in general. Since 2004, the share of persons with higher education has increased from 27 to 33 per cent. Employees in the power supply sector are on an average older than the employees in the private sector. The employees have matured since 2004, but in the last few years, there have also been signs of fresh recruitment. The power supply industry had a net influx of 347 new employees, or 2 percent, in the period between 2009 and 2010. There were 1522 new employees and 1175 employees lost in the sector due to attrition, which gives a turnover rate of 20 percent. If we look at the supply of new employees who were also employed in 2009, 19 percent of female employees worked in temporary staff recruitment agencies. This indicates that temporary work was an entry gate to the power supply industry for many women. Among men, the building- and construction sector was the most common background for

  9. Supply and demand perspectives

    International Nuclear Information System (INIS)

    The outlook for the European gas market is one of steady growth. This growth will manifest itself in all regions and in all sectors of the market, but most strongly in the power generating sector. To meet future demand, it is necessary to bring gas to Western Europe from remote sources in Russia, North Africa and Norway. These new gas supplies require heavy investments in production and transportation, which can only be undertaken on the basis of long-term take-or-pay contracts. Famous examples of such contracts are the development of the Troll field, the Yamal-Europe pipeline connection, and the bringing on stream of Nigerian LNG for Europe. Tensions are likely to arise between the nature of these long-term gas contracts and the dynamic nature of demand in the gas market, and more specifically in the main growth market, the power sector.

    Full Text Available Building resilient supply chain is an effective way to deal with uncertain risks. First, by analyzing the self-organization of supply chain, the supply chain resilience is described as a macroscopic property that generates from self-organizing behavior of each enterprise on the microlevel. Second, a MAS-based supply chain resilience model is established and its local fitness function, neighborhood structure, and interaction rules that are applicable to supply chain system are designed through viewing the enterprise as an agent. Finally, with the help of a case, we find that there is an agglomeration effect and a SOC characteristic in supply chain and the evolution of supply chain is controlled by parameters of MAS. Managers can control the supply chain within the resilient range and choose a good balance between interest and risk by controlling enterprises’ behavior.

  8. Optics Supply Planning System

    International Nuclear Information System (INIS)

    The purpose of this study is to specify the design for an initial optics supply planning system for NIF, and to present quality assurance and test plans for the construction of the system as specified. The National Ignition Facility (NIF) is a large laser facility that is just starting operations. Thousands of specialized optics are required to operate the laser, and must be exchanged over time based on the laser shot plan and predictions of damage. Careful planning and tracking of optic exchanges is necessary because of the tight inventory of spare optics, and the long lead times for optics procurements and production changes. Automated inventory forecasting and production planning tools are required to replace existing manual processes. The optics groups members who are expected to use the supply planning system are the stakeholders for this project, and are divided into three groups. Each of these groups participated in a requirements specification that was used to develop this design. (1) Optics Management--These are the top level stakeholdersk, and the final decision makers. This group is the interface to shot operations, is ultimately responsible for optics supply, and decides which exchanges will be made. (2) Work Center Managers--This group manages the on site optics processing work centers. They schedule the daily work center operations, and are responsible for developing long term processing, equipment, and staffing plans. (3) Component Engineers--This group manages the vendor contracts for the manufacture of new optics and the off site rework of existing optics. They are responsible for sourcing vendors, negotiating contracts, and managing vendor processes. The scope of this analysis is to describe the structure and design details of a system that will meet all requirements that were described by stakeholders and documented in the analysis model for this project. The design specifies the architecture, components, interfaces, and data stores of the system

    1979-01-01

    The power supply system which will energize the superconducting magnets in the ISABELLE machine consists of some 520 computer-programmable power supplies with outputs ranging from 50 A to 4500 A. Most of the power supplies will be used for the correction of field harmonics, orbit correction and adjustment of the machine working line. During acceleration, currents in various magnet correction coils will be controlled in real time to track the main field; all power supplies must be highly stable during the stacking and storage of the beam (in some cases current regulation must be in the order of 0.001%). PS reference programs will be stored in microprocessor based function generators embedded in each power supply. Due to the large amount of stored energy in the system, the magnets must be protected during quenches. Details of the power supply and of the magnet quench protection system are described.

    The report's main objective is to investigate employment within the power supply industry and the power supply related activities. The report will describe the composition of employees in regard to sex, age and education. The power supply industry is defined in Statistics Norway's Standard Industrial Classification, as 'Production and distribution of electricity'. The group of companies related to power supply related activities employ similar persons in regard to education and occupation, typical to companies in the power supply industry. These two groups make up the power supply sector in this report. In 2011 there were 18 450 employees in the power supply sector. This constitutes an increase of nearly 13.5 per cent since 2004 and 1.1 per cent since 2010. The sex distribution of about 80 per cent men and 20 per cent women has been fairly stable since 2004. The power supply sector has a low share of women among its employees compared to the private sector in general. In 2011 the level of education in the power supply sector was higher than for the private sector in general. Since 2004, the share of persons with higher education has increased from 27 to 33 per cent. Employees in the power supply sector are on average older than employees in the private sector. The employees have matured since 2004, but in the last few years, there have also been signs of fresh recruitment. The power supply industry had a net influx of 380 new employees, in the period between 2009 and 2011. There were 1678 new employees and 1298 employees lost in the sector due to attrition. If we look at the supply of new employees who were also employed in 2010, 14.2 percent of female employees worked in temporary staff recruitment agencies. Temporary work seems to be an important entry gate to the power supply industry for women. Among men, the building- and construction sector was the most common background for new employees in the power supply industry. Among people who quit

    We examine the impact of relative wages on labor supply in a laboratory experiment. We test the hypothesis that, ceteris paribus, making a given wage high (low) relative to other wage levels will lead to an increase (decrease) in labor supply. We find that labor supply does respond significantly to relative pay, and in the expected direction. However, when a strong enough reason for the relative low pay is given, this difference disappears.

  18. Reliability Estimates for Power Supplies

    International Nuclear Information System (INIS)

    Failure rates for large power supplies at a fusion facility are critical knowledge needed to estimate availability of the facility or to set priorities for repairs and spare components. A study of the ''failure to operate on demand'' and ''failure to continue to operate'' failure rates has been performed for the large power supplies at DIII-D, which provide power to the magnet coils, the neutral beam injectors, the electron cyclotron heating systems, and the fast wave systems. When one of the power supplies fails to operate, the research program has to be either temporarily changed or halted. If one of the power supplies for the toroidal or ohmic heating coils fails, the operations have to be suspended or the research is continued at de-rated parameters until a repair is completed. If one of the power supplies used in the auxiliary plasma heating systems fails the research is often temporarily changed until a repair is completed. The power supplies are operated remotely and repairs are only performed when the power supplies are off line, so that failure of a power supply does not cause any risk to personnel. The DIII-D Trouble Report database was used to determine the number of power supply faults (over 1,700 reports), and tokamak annual operations data supplied the number of shots, operating times, and power supply usage for the DIII-D operating campaigns between mid-1987 and 2004. Where possible, these power supply failure rates from DIII-D will be compared to similar work that has been performed for the Joint European Torus equipment. These independent data sets support validation of the fusion-specific failure rate values

  19. Estimating Swedish biomass energy supply

    International Nuclear Information System (INIS)

    Biomass is suggested to supply an increasing amount of energy in Sweden. There have been several studies estimating the potential supply of biomass energy, including that of the Swedish Energy Commission in 1995. The Energy Commission based its estimates of biomass supply on five other analyses which presented a wide variation in estimated future supply, in large part due to differing assumptions regarding important factors. In this paper, these studies are assessed, and the estimated potential biomass energy supplies are discusses regarding prices, technical progress and energy policy. The supply of logging residues depends on the demand for wood products and is limited by ecological, technological, and economic restrictions. The supply of stemwood from early thinning for energy and of straw from cereal and oil seed production is mainly dependent upon economic considerations. One major factor for the supply of willow and reed canary grass is the size of arable land projected to be not needed for food and fodder production. Future supply of biomass energy depends on energy prices and technical progress, both of which are driven by energy policy priorities. Biomass energy has to compete with other energy sources as well as with alternative uses of biomass such as forest products and food production. Technical progress may decrease the costs of biomass energy and thus increase the competitiveness. Economic instruments, including carbon taxes and subsidies, and allocation of research and development resources, are driven by energy policy goals and can change the competitiveness of biomass energy

    A switching mode power supply (SMPS) is a hopeful candidate for the 1 MW CW klystron power supply of KOMAC (KOrea Multi-purpose Accelerator Complex). The merits of the SMPS are low stored energy, small size, high rating efficiency and possible cost saving whereas the demerits are EMI problem and system complexities. The proposed power is 2 MW and it is considered that the modules, each of which has the power of 200 kW, are connected in series to supply the total power. As a first step, a 200 kW SMPS is studied and designed. An overview of the power supply designed so far is presented. (author)

    Rego, Nazaré; de Sousa, Jorge Pinho

    This paper presents an innovative approach to support the definition of strategies for the design of alternative configurations of hospital supply chains. This approach was developed around a hybrid Tabu Search / Variable Neighbourhood Search metaheuristic, that uses several neighbourhood structures. The flexibility of the procedure allows its application to supply chains with different topologies and atypical cost characteristics. A preliminary computational experience shows the approach potential in solving large scale supply chain configuration problems. The future incorporation of this approach in a broader Decision Support System (DSS) will provide a tool that can significantly contribute to an increase of healthcare supply chains efficiency and encourage the establishment of collaborative partnerships between their members.

  6. Zapping the food supply

    International Nuclear Information System (INIS)

    The idea of exposing food to gamma radiation is over 30 years old, and in 1963 the Food and Drug Administration (FDA) began to permit the irradiation of wheat. Over the years, a few more foodstuffs such as spices and tea were added, but in 1984 the FDA started to approve irradiation of a much broader list of products which now includes meat, poultry, and fresh fruits and vegetables. Simultaneously the FDA has increased the levels of radiation that may be used. The FDA's recent willingness to allow most of the food supply to be irradiated - and at high doses - has triggered an acrimonious debate. The amount of radiation involved is substantial, with intensities millions of times greater than that of an ordinary chest X-ray. The announced goal of promoters of food irradiation is to obtain general approval for the use of up to one million rad. Irradiation does not make food radioactive, nor has alleged radioactivity been at issue in the debate. But there is concern that foods processed by irradiation may contain radiolytic products that could have toxic effects. 12 refs

  7. Supply, demand and costs

    International Nuclear Information System (INIS)

    Most of the proven reactor types envisaged for commercial operation over the next two decades require enriched uranium. Even assuming a larger share for natural uranium fueled heavy water systems and an early date of introduction for breeders on a commercial scale, enriched uranium fueled stations are likely to represent the bulk of the new nuclear capacity to be installed between now and the turn of the century. Hence the problem of ensuring an adequate supply of enrichment services at the lowest possible cost is just as important as that of securing a solid basis of uranium ore reserves. The present enrichment capacity available in the western world is likely to be exhausted in the early 1980's, the exact date depending on the rate of growth of nuclear capacity and on plausible variations in the proportions of different reactor types. Since the lead time between consideration and commissioning of an enrichment plant is of the order of 8 to 10 years, and since the issue has significant national, regional and international aspects on the commercial and political levels, it has recently been in the forefront of interest, and no review of nuclear power prospects would be complete without its consideration. The demand for separative work depends on the demand for enriched uranium, on the enrichment levels of the fuel and of the enrichment plant tails. The demand for enriched uranium is in turn determined by the nuclear power demand, the reactor strategy, reactor characteristics, capacity factor, delay times, and plutonium recycle policy

  8. Economy of wood supply

    International Nuclear Information System (INIS)

    Research and development of wood fuels production was vigorous in the beginning of the 1980's. Techniques and working methods used in combined harvesting and transportation of energy and merchantable wood were developed in addition to separate energy wood delivery. After a ten year silent period the research on this field was started again. At present the underutilization of forest supplies and the environmental effects of energy production based on fossil fuels caused the rebeginning of the research. One alternative for reduction of the price of wood fuels at the utilization site is the integration of energy and merchantable wood deliveries together. Hence the harvesting and transportation devices can be operated effectively, and the organizational costs are decreased as well. The wood delivery costs consist of the stumpage price, the harvesting and transportation costs, and of general expenses. The stumpage price form the largest cost category (over 50 %) of the industrial merchantable wood delivery, and the harvesting and transportation costs in the case of thinningwood delivery. Forest transportation is the largest part of the delivery costs of logging residues. The general expenses, consisting of the management costs and the interest costs of the capital bound to the storages, form a remarkable cost category in delivery of low-rank wood for energy or conversion purposes. The costs caused by the harvesting of thinningwood, the logging residues, chipping and crushing, the lorry transportation are reviewed in this presentation

  10. Water demand and supply

    International Nuclear Information System (INIS)

    Major international conferences have dealt with the growing concern over the ever increasing use of limited fresh water resources on the planet, including the United Nations Water Conference held in Mar del Plata (1977), the Dublin Conference (1992) and the UN Conference on Environment and Development held in Rio de Janeiro (1992). In April 1997, the UN Commission on Sustainable Development was presented with a report on a Comprehensive Assessment of the Freshwater Resources of the World, in which all UN agencies concerned with water participated. Matching the ever growing demands with the limited supply of a finite resource has led to tremendous stress on natural fresh water. This starts with low water stress, when about 10% of the available fresh water is being used. Use of more than 40% of the available water indicates serious scarcity, and usually increasing dependence on desalination and overexploitation of aquifers. On the basis of population increase projections for the year 2025, and extrapolating current trends, as much as two-thirds of the world's population may be living in moderate or high water stress situations. With increasing water stress and scarcity, drastic changes in the way water business is being done will have to be introduced, particularly in low income countries. Agricultural practices, in particular, have to be introduced that reduce losses. Improved strategies have to make use of rigorously enforced demand management, better resource management, waste water reuse to the extent possible, and finally desalination of sea water and brackish groundwaters. Some of the current water intensive patterns of development may even have to be abandoned. (author)

  13. Seismic Safety Of Simple Masonry Buildings

    International Nuclear Information System (INIS)

    Several masonry buildings comply with the rules for simple buildings provided by seismic codes. For these buildings explicit safety verifications are not compulsory if specific code rules are fulfilled. In fact it is assumed that their fulfilment ensures a suitable seismic behaviour of buildings and thus adequate safety under earthquakes. Italian and European seismic codes differ in the requirements for simple masonry buildings, mostly concerning the building typology, the building geometry and the acceleration at site. Obviously, a wide percentage of buildings assumed simple by codes should satisfy the numerical safety verification, so that no confusion and uncertainty have to be given rise to designers who must use the codes. This paper aims at evaluating the seismic response of some simple unreinforced masonry buildings that comply with the provisions of the new Italian seismic code. Two-story buildings, having different geometry, are analysed and results from nonlinear static analyses performed by varying the acceleration at site are presented and discussed. Indications on the congruence between code rules and results of numerical analyses performed according to the code itself are supplied and, in this context, the obtained result can provide a contribution for improving the seismic code requirements

  17. A simulation approach for analysis of short-term security of natural gas supply in Colombia

    International Nuclear Information System (INIS)

    Achieving security of gas supply implies diversifying gas sources, while having enough supply, transportation, and storage capacity to meet demand peaks and supply interruptions. Devising a strategy for securing gas supply is not straightforward because gas supply depends on complex interactions of production, demand and infrastructure, and it is exposed to economic, regulatory, political, environmental and technical risks. To address this complexity, we propose a simulation approach that replicates the structure of the gas supply chain, including transportation constraints and demand fluctuations. We build and calibrate a computer model for the Colombian gas sector, and run the model to assess the impact of expanding transportation capacity and increasing market flexibility on the security of supply. Our analysis focuses on the operation and planned and proposed expansions of the transportation infrastructure because adequate regulation and development of this infrastructure can contribute to increase the security of supply in the gas sector. We find that proposed import facilities, specifically LNG import terminals at Buenaventura, increase system's security under the current market structure. - Highlights: ► We build a simulation model for analyzing natural gas trade in Colombia. ► The model captures the structure of the gas network and on market rules. ► We simulate investment decisions to increase short-term security of supply. ► Securing supply would need LNG imports and expansion of pipeline capacity.

    Full Text Available The anaesthesia gas supply system is designed to provide a safe, cost-effective and convenient system for the delivery of medical gases at the point of-use. The doctrine of the anaesthesia gas supply system is based on four essential principles: Identity, continuity, adequacy and quality. Knowledge about gas supply system is an integral component of safe anaesthetic practice. Mishaps involving the malfunction or misuse of medical gas supply to operating theatres have cost many lives. The medical gases used in anaesthesia and intensive care are oxygen, nitrous oxide, medical air, entonox, carbon dioxide and heliox. Oxygen is one of the most widely used gases for life-support and respiratory therapy besides anaesthetic procedures. In this article, an effort is made to describe the production, storage and delivery of anaesthetic gases. The design of anaesthesia equipment must take into account the local conditions such as climate, demand and power supply. The operational policy of the gas supply system should have a backup plan to cater to the emergency need of the hospital, in the event of the loss of the primary source of supply.

  10. Supply ships powered by liquid natural gas

    International Nuclear Information System (INIS)

    The Norwegian Government has signed an agreement with three Norwegian companies to build two new supply ships that will use cooled liquid natural gas as a fuel (LNG). The new ships will supply the offshore installations in the North Sea. The greatest advantage for the environment is the fact that the emission of nitrogen oxides is reduced by 85 per cent compared to conventional diesel power. The emission of carbon dioxide is reduced by 20 to 30 per cent. For Norway to be able to fulfil its international environmental commitments the authorities must make it possible for all coastal traffic to use natural gas for fuel in the future. The cost of reducing the NOx emissions directly by using the new gas-powered ships is several times smaller than the cost of obtaining the same reduction on the land bases. If all the Norwegian coastal traffic converted from diesel to natural gas, this would have fulfilled 70 per cent of the country's commitment according to the Gothenburg Protocol

    Full Text Available In recent years information integration became significant problem for both natural and legal persons in everyday operations. Huge amount of information are available, but insufficiently processed in order to have useful value. Choosing the right combination of tools and technologies for integration is prerequisite for requiring information from multiple heterogeneous sources and their qualitative and simple using after.In this paper, we have focused on information integration within companies which are parts of supply chain or network. This environment typically includes a various mix of sources, structured (such as relational or other databases, and unstructured (such as document repositories, spreadsheets, documents, web pages, emails and others. Effective information integration and sharing significantly enhances supply chain practices. Service oriented architecture (SOA is an architectural style for building software applications that use services available in a network such as the web. The use of SOA to achieve inter-enterprise supply network information integration has many advantages.

  16. Large turbogenerators as high power supply for plasma physics research

    International Nuclear Information System (INIS)

    Many countries nowadays design and build research equipments for investigations on the field of plasma physics, requiring very high pulsed power supplies. Such supplies with DC-current output have not only to be powerful, but also quickly regulable. Peak capacities over 500 MW and energy amounts of some Gigajoule for a pulse duration of a few seconds cannot be delivered by a high voltage utility network, wihout untolerable voltage drops or marked current and voltage harmonics occuring. These negative influences can be greatly eliminated by using an intermediate energy storage. In this idea the utilization of a large turbogenerator - with or without suppplementary flywheel - represents an advantageous solution. In this paper the simulation of such power supplies is presented. On the base of three actual examples, the behaviour and the stresses of the generator, as well as its influence on the transient phenomena in the whole system are analyzed and explained. (orig.)

    2016-07-01

    Full Text Available The world’s habitat is being deteriorated despite of the precautions taken. Construction industry is among the industries which highly effect the environment adversely not only through its outputs but also through the construction process and its inputs. The main focus in dealing with the reduction of its footprint has been on sustainable building certificates which mainly analyse the output of the construction activies. There is need to analyse the construction supply chain as a whole and to embed sustainability dynamics in construction supply chain management. Lean construction project management contributes to the reduction of the environmental footprint of the construction industry, enabling reduction in waste, and increasing value added activities. For this reason, based on an in depth literature review, this paper analyses and establishes the principles of the integration of the sustainability dynamics into lean construction supply chain management.

  18. The 3He Supply Problem

    Energy Technology Data Exchange (ETDEWEB)

    Kouzes, Richard T.

    2009-05-01

    One of the main uses for 3He is in gas proportional counters for neutron detection. Radiation portal monitors deployed for homeland security and non-proliferation use such detectors. Other uses of 3He are for research detectors, commercial instruments, well logging detectors, dilution refrigerators, for targets or cooling in nuclear research, and for basic research in condensed matter physics. The US supply of 3He comes almost entirely from the decay of tritium used in nuclear weapons by the US and Russia. A few other countries contribute a small amount to the world’s 3He supply. Due to the large increase in use of 3He for homeland security, the supply has dwindled, and can no longer meet the demand. This white paper reviews the problems of supply, utilization, and alternatives.

    Builders generally use a 'spec and purchase' business management system (BMS) when implementing energy efficiency. A BMS is the overall operational and organizational systems and strategies that a builder uses to set up and run its company. This type of BMS treats building performance as a simple technology swap (e.g. a tank water heater to a tankless water heater) and typically compartmentalizes energy efficiency within one or two groups in the organization (e.g. purchasing and construction). While certain tools, such as details, checklists, and scopes of work, can assist builders in managing the quality of the construction of higher performance homes, they do nothing to address the underlying operational strategies and issues related to change management that builders face when they make high performance homes a core part of their mission. To achieve the systems integration necessary for attaining 40% + levels of energy efficiency, while capturing the cost tradeoffs, builders must use a 'systems approach' BMS, rather than a 'spec and purchase' BMS. The following attributes are inherent in a systems approach BMS; they are also generally seen in quality management systems (QMS), such as the National Housing Quality Certification program: Cultural and corporate alignment, Clear intent for quality and performance, Increased collaboration across internal and external teams, Better communication practices and systems, Disciplined approach to quality control, Measurement and verification of performance, Continuous feedback and improvement, and Whole house integrated design and specification.

  16. Forecasting world natural gas supply

    International Nuclear Information System (INIS)

    Using the multi-cyclic Hubert approach, a 53 country-specific gas supply model was developed which enables production forecasts for virtually all of the world's gas. Supply models for some organizations such as OPEC, non-OPEC and OECD were also developed and analyzed. Results of the modeling study indicate that the world's supply of natural gas will peak in 2014, followed by an annual decline at the rate of one per cent per year. North American gas production is reported to be currently at its peak with 29 Tcf/yr; Western Europe will reach its peak supply in 2002 with 12 Tcf. According to this forecast the main sources of natural gas supply in the future will be the countries of the former Soviet Union and the Middle East. Between them, they possess about 62 per cent of the world's ultimate recoverable natural gas (4,880 Tcf). It should be noted that these estimates do not include unconventional gas resulting from tight gas reservoirs, coalbed methane, gas shales and gas hydrates. These unconventional sources will undoubtedly play an important role in the gas supply in countries such as the United States and Canada. 18 refs., 2 tabs., 18 figs

'Activate' was an evolution of this idea and there was a hole in the market for a lively, activity and article based magazine that could be used in the classroom. The target audience is principally teachers of science, mathematics and geography, but also includes teachers of art,, English and history with students of between 11 and 18. The results were very positive in that teachers appreciated the colourful and lively nature of activate and they felt that it provided information and opinions in an un biased and non-propagandist way. Their comments about layout, number of activities style of presentation were taken into account and during the summer of 1994 activate was remodelled ready for re launch in September. The feedback so far is good with more teachers signing up every week to receive their own free copy

    International Nuclear Information System (INIS)

    The paper is the synthesis of two lectures on the energy market in the FRG and the problems of the future energy supply. The main point of the explanations is nuclear energy and power supply the basic thoughts of which are explained in detail. A general view at the present situation on the individual energy sections shows that by using regenerative energy sources and energy savings only the increasing energy need cannot be met. Also in the case of coal, when having used it for a long time through the technologies of gasification and liquidation, its quantitative limits will be seen sooner than it would be the case otherwise. For long terms, nuclear energy is the only way to guarantee the mankind a relatively rishless supply of energy in the generation of power and process heat, especially when the fast breeders are used.

    2016-04-01

    Extreme weather conditions in Hungary led to difficulties in drinking water management on diverse occasions in the past. Due to reduced water resources and the coexisting high demand for drinking water in dry summer periods the availability of a number of water supplies became insufficient therefore causing limitations in water access. In some other cases, as a result of floods and flash floods over karstic areas evolving in consequence of excessive precipitation, several water supplies had to be excluded in order to avoid the risk of infections. More frequent occurrence of extreme weather conditions and further possible changes in the future induce the necessity for an analysis of the vulnerability of drinking water resources to climate change. Since 95% of the total drinking water supply in Hungary originates from subsurface layers, significance of groundwater resources is outstanding. The aim of our work carried out in the frames of the NAGiS (National Adaptation Geo-information System) project was to build up a methodology for the study and determination of the vulnerability of drinking water supplies to climate. The task covered analyses of climatic parameters influencing drinking water supplies principally and hydrogeological characteristics of the geological media that significantly determines vulnerability. Effects on drinking water resources and their reduction or exclusion may imply societal and economic consequences therefore we extended the analyses to the investigation of possibilities concerning the adaptation capacity to changed conditions. We applied the CIVAS (Climate Impact and Vulnerability Assessment Scheme) model developed in the frames of the international climate research project CLAVIER (Climate Change and Variability: Impact on Central and Eastern Europe) to characterize climate vulnerability of drinking water supplies. The CIVAS model, being based on the combined evaluation of exposure, sensitivity and adaptability, provides a unified

  17. LPG world supply and demand

    International Nuclear Information System (INIS)

    Over the course of this decade, the global LPG market has moved from being tight, where supply barely exceeded non-price sensitive demand, to the current market situation where supply growth has outstripped demand growth to such an extent that current fundamentals suggest that considerable length will prevail in the market over the near term. As is the case for many other energy commodity markets, the LPG industry has experienced a considerable transformation over the last five years with many new LPG supply projects coming on-stream and demand growth in many developing markets slowing in response to higher energy prices. The near term challenge for LPG producers will be securing outlets for output as the market becomes increasingly oversupplied. With expanding LPG supply and a worldwide tightness in the naphtha market, it is expected that petrochemical consumers will favor relatively low priced LPG over naphtha and the resulting increase in LPG cracking rates will go some way to reducing the expected supply surplus. However, the timing of several new LPG supply projects and the start-up of LPG-based petrochemical plants in the Middle-East are expected to impact global LPG trade and pricing over the next few years. Thus, at this point in time, the global LPG market has a high degree of uncertainty with questions remaining over the impact of high energy (and LPG) prices on traditional and developing market demand, the timing of new supply projects and the combined effect of these two factors on international LPG prices. World LPG production has been rising in nearly every region of the world over the last few years and totaled about 229 million tons in 2007, which is some 30 million tons per year higher than in 2000. The exception is North America which accounts for the largest share of global LPG supply at about 24% but production there has remained relatively flat in recent years. Strong LPG production growth in the Middle-East which contributed to about 19% of

  1. Supply mix advice and recommendations : supply mix summary

    International Nuclear Information System (INIS)

    Ontario's electricity sector is at one of its most challenging points in history. The system has less capacity than it did 12 years ago, and demand has increased because of population and economic growth. A projected province-wide shortfall in supply capacity is anticipated in the next 5 years, which will continue to grow over time. This report presented recommendations from the Ontario Power Authority (OPA) on options for the future development of Ontario's electricity system. The report was prepared as a response to the Minister of Energy's request for advice on the appropriate mix of electricity supply sources to satisfy the expected demand in Ontario, while taking into account conservation targets and new sources of renewable energy up to 2025. Many of the most attractive options for meeting base-load generation requirements entail long lead-times, and choices that focus only on immediate needs may foreclose more attractive options for the future. It was suggested that conservation and new renewable sources will meet Ontario's growth in demand for electricity by 2025. However, they will not replace the loss of capacity from the retirement of other supply sources such as nuclear and coal-fired generation stations. It was suggested that gas-fired generation be used to relieve transmission bottlenecks as well as for district energy and cogeneration. Recommendations included maximizing conservation and pursuing an aggressive course for renewables within current constraints while looking at ways to reduce constraints. It was suggested that a smart gas strategy should be adopted that takes advantage of the benefits of natural gas fired generation but limits exposure to its price and supply risks. Supply options that need long lead times such as nuclear, large-scale wind generation, hydro imports and gasification were also recommended. 4 figs

    Paxton, Joseph; Tucker, Brian

    2010-01-01

    This paper will present a model that uses the Supply-Chain Operations Reference (SCOR) model as a foundation for a framework to illustrate the information needed throughout a product lifecycle to support a healthy supply chain management function and the subsequent contract requirements to enable it. It will also show where in the supply chain the information must be extracted. The ongoing case study used to exemplify the model is NASA's (National Aeronautics and Space Administration) Ares I program for human spaceflight. Effective supply chain management and contract requirements are ongoing opportunities for continuous improvement within government agencies, specifically development of systems for human spaceflight operations. Multiple reports from the Government Accountability Office (GAO) reinforce this importance. The SCOR model is a framework for describing a supply chain with process building blocks and business activities. It provides a set of metrics for measuring supply chain performance and best practices for continuously improving. This paper expands the application of the SCOR to also provide the framework for defining information needed from different levels of the supply chain and at different phases of the lifecycle. These needs can be incorporated into contracts to enable more effective supply chain management. Depending on the phase of the lifecycle, effective supply chain management will require involvement from different levels of the organization and different levels of the supply chain.

  5. Occupational radiation exposure in upper Austrian water supplies and Spas

    International Nuclear Information System (INIS)

    The Council Directive 96/29/EURATOM lays down the basic safety standards for the protection of the workers and the general public against the dangers arising from ionising radiation, including natural radiation. Based on the directive and on the corresponding Austrian legislation a comprehensive study was conducted to determine the occupational radiation exposure in Upper Austrian water supplies and spas. The study comprises 45 water supplies and 3 spas, one of them being a radon spa. Most measurements taken were to determine the radon concentration in air at different workplaces (n = 184), but also measurements of the dose rate at dehumidifiers (n = 7) and gamma spectrometric measurements of back washing water (n = 4) were conducted. To determine the maximum occupational radon exposure in a water supply measurements were carried out in all water purification buildings and in at least half o f the drinking water reservoirs of the water supply. The results were combined with the respective working times in these locations (these data having been collected by means of a questionnaire). Where the calculated exposure was greater than 1 MBq h/m then all drinking water reservoirs of the concerned water suppl y were measured for their radon concentration to ensure a reliable assessment of the exposure. The results show that the radon concentrations in the water supplies were lower as expected, being in 55% of all measurement sites below 1000 Bq/m in 91% below 5000 Bq/m and with a maximum value of 38700 Bq/m.This leads to exposures that are below 2 MBq h/m (corresponding to approx. 6 mSv/a) in 42 water supplies. However, for the remaining three water supplies maximal occupational exposures due to radon of 2.8 MBq h/m (∼ 10 mSv/a), 15 MBq h/m (∼ 50 mSv/a), and 17 MBq h/m ( ∼ 56 mSv/a), respectively, were determined. In these water supplies remediation measures were proposed, based mainly on improved ventilation of and/or reduction of working time in the building(s

  2. Water Supply Infrastructure System Surety

    Energy Technology Data Exchange (ETDEWEB)

    EKMAN,MARK E.; ISBELL,DARYL

    2000-01-06

    The executive branch of the United States government has acknowledged and identified threats to the water supply infrastructure of the United States. These threats include contamination of the water supply, aging infrastructure components, and malicious attack. Government recognition of the importance of providing safe, secure, and reliable water supplies has a historical precedence in the water works of the ancient Romans, who recognized the same basic threats to their water supply infrastructure the United States acknowledges today. System surety is the philosophy of ''designing for threats, planning for failure, and managing for success'' in system design and implementation. System surety is an alternative to traditional compliance-based approaches to safety, security, and reliability. Four types of surety are recognized: reactive surety; proactive surety, preventative surety; and fundamental, inherent surety. The five steps of the system surety approach can be used to establish the type of surety needed for the water infrastructure and the methods used to realize a sure water infrastructure. The benefit to the water industry of using the system surety approach to infrastructure design and assessment is a proactive approach to safety, security, and reliability for water transmission, treatment, distribution, and wastewater collection and treatment.

  3. Supply Curves of Conserved Energy

    Energy Technology Data Exchange (ETDEWEB)

    Meier, Alan Kevin

    1982-05-01

    Supply curves of conserved energy provide an accounting framework that expresses the potential for energy conservation. The economic worthiness of a conservation measure is expressed in terms of the cost of conserved energy, and a measure is considered economical when the cost of conserved energy is less than the price of the energy it replaces. A supply curve of conserved energy is independent of energy prices; however, the economical reserves of conserved energy will depend on energy prices. Double-counting of energy savings and error propagation are common problems when estimating conservation potentials, but supply curves minimize these difficulties and make their consequences predictable. The sensitivity of the cost of conserved energy is examined, as are variations in the optimal investment strategy in response to changes in inputs. Guidelines are presented for predicting the consequences of such changes. The conservation supply curve concept can be applied to peak power, water, pollution, and other markets where consumers demand a service rather than a particular good.

  4. Dietary mineral supplies in Africa.

    Dietary micronutrient deficiencies (MNDs) are widespread, yet their prevalence can be difficult to assess. Here, we estimate MND risks due to inadequate intakes for seven minerals in Africa using food supply and composition data, and consider the potential of food-based and agricultural interventions. Food Balance Sheets (FBSs) for 46 countries were integrated with food composition data to estimate per capita supply of calcium (Ca), copper (Cu), iron (Fe), iodine (I), magnesium (Mg), selenium (Se) and zinc (Zn), and also phytate. Deficiency risks were quantified using an estimated average requirement (EAR) 'cut-point' approach. Deficiency risks are highest for Ca (54% of the population), followed by Zn (40%), Se (28%) and I (19%, after accounting for iodized salt consumption). The risk of Cu (1%) and Mg (risks are generally lower in the north and west of Africa. Multiple MND risks are high in many countries. The population-weighted mean phytate supply is 2770 mg capita(-1) day(-1). Deficiency risks for Fe are lower than expected (5%). However, 'cut-point' approaches for Fe are sensitive to assumptions regarding requirements; e.g. estimates of Fe deficiency risks are 43% under very low bioavailability scenarios consistent with high-phytate, low-animal protein diets. Fertilization and breeding strategies could greatly reduce certain MNDs. For example, meeting HarvestPlus breeding targets for Zn would reduce dietary Zn deficiency risk by 90% based on supply data. Dietary diversification or direct fortification is likely to be needed to address Ca deficiency risks. PMID:24524331

  5. Competitive behaviour in supply chains

    Directory of Open Access Journals (Sweden)

    Sylwia Konecka

    2014-06-01

    Full Text Available Background: The article deals with the results of literature and empirical research into competitiveness and behaviour of entities in supply chains. Methods: A research hypothesis has been formulated that both partnership as well as dominance relations occur between enterprises functioning as suppliers-consignees. In order to verify the hypothesis a survey was completed in 2012. It encompassed 116 enterprises (manufacturers - 33, service providers - 32 and sellers - 24 as well as enterprises selling goods and providing services - 27 of which 54 were large, 26 medium and 36 were small enterprises. Competitive behaviour in supply chains has been identified and analysed. Furthermore, the authors intended to identify, reveal and examine possible interdependences between competitive behaviour and behaviour typical of supply chain strategies. Results and conclusions: The analysis of survey results revealed a tendency to preserve equilibrium between a chain leader and dependent enterprises. It may be easily justified in practice as on the one hand there is a need to keep the supply chain competitive and on the other hand to avoid the interruptions, which could occur as a result of elimination of dependent enterprises.

    Data presented in the Petroleum Supply Monthly (PSM) describe the supply and disposition of petroleum products in the United States and major US geographic regions. The data series describe production, imports and exports, inter-Petroleum Administration for Defense (PAD) District movements, and inventories by the primary suppliers of petroleum products in the United States (50 States and the District of Columbia). The reporting universe includes those petroleum sectors in primary supply. Included are: petroleum refiners, motor gasoline blenders, operators of natural gas processing plants and fractionators, inter-PAD transporters, importers, and major inventory holders of petroleum products and crude oil. When aggregated, the data reported by these sectors approximately represent the consumption of petroleum products in the United States. Data presented in the PSM are divided into two sections: Summary Statistics and Detailed Statistics. The tables and figures ih the Summary Statistics section of the PSM present a time series of selected petroleum data on a US level. Most time series include preliminary estimates for one month based on the Weekly Petroleum Supply Reporting System; statistics based on the most recent data from the Monthly Petroleum Supply Reporting System (MPSRS); and statistics published in prior issues of the PSM and PSA. The Detailed Statistics tables of the PSM present statistics for the most current month available as well as year-to-date. In most cases, the statistics are presented for several geographic areas - - the United States (50 States and the District of Columbia), five PAD Districts, and 12 Refining Districts. At the US and PAD District level, the total volume and the daily rate of activities are presented. The statistics are developed from monthly survey forms submitted by respondents to the EIA and from data provided firom other sources.

    Zhang, X. H.; Zhang, H. W.; Chen, B.; Guo, H. C.; Chen, G. Q.; Zhao, B. A.

    2009-01-01

    This paper introduces an inexact-stochastic dual water supply programming (ISDWSP) model based on analysis of the inexact characteristics in demand and supply subsystems of dual water supply system and their dynamic interactions. The model is based on an inexact chance-constrained programming (ICCP) method allowing both distribution information in B (right parameter in the model constrain) and uncertainties in A (left parameter in the model constrain) and C (parameter in the model function) with objective of maximizing economic return, and constrained to available water resource, economical, environmental and social constrains. The decision-making variables of ISDWSP model are water demanded amount by different sectors and waterworks building scale. In the solution process, the ISDWSP is transformed into two deterministic sub-models, which correspond to the upper and lower bounds of the objective function, and the reasonable interval solution set in the given decision space can be obtained by solving the two sub-models. Thus, decision alternatives can be obtained by adjusting decision variable values within their solution intervals and will be useful for decision makers to choose the projected applicable conditions considering tradeoffs between eco-environmental and economic objectives. The model is also applied in a new developing zone of North China with the results of the case study providing reasonable solutions for dynamic planning of different source water (DSW) allocation in a regional system. Finally, waterworks building plan is generated based on the projected applicable conditions.

  6. Mineral supply constraints necessitate a global policy response

    Nickless, Edmund

    2016-04-01

    Adoption on 12 December 2015 of The Paris Agreement, the first universal climate agreement, suggests that nations will invest in infrastructures for renewable energy sources paving the way to a global low-carbon society. These large-scale changes will require vast amounts of metals and minerals. Regardless of whether known supplies are enough to meet demand in the near future, efforts must be made now to forestall unpredictable yet inevitable supply shortages in the decades to come, shortages that would dramatically impact the building of additional generation and distribution capacity, and deployment of low-carbon technology. But in response to the current downturn in commodity prices, the global mining industry is downsizing and reducing investment in the new exploration, putting at risk future security of supply. Mining and climate change are inextricably linked; the new adaptive technologies needed to tackle climate change depend on extraction of minerals and metals. An interdisciplinary group supported by the International Union of Geological Sciences, the International Council for Science Unions and UNESCO proposes measures to avert the looming minerals crisis that is developing in the context of current recycling capacity and exploration trends. Our immediate goal is to stimulate discussion of supply constraints using available data on mineral reserves. We build on recent discussions of supply risk and criticality with a focus on the source of primary resources over the next two to three decades when the availability of metals for recycling will remain low. Current massive production of iron ore and other such commodities despite record low prices indicates a failure of the traditional supply and demand constraints. Broader discussions of metal and mineral supply beyond current criticality are needed given the pace of technological and demographic change as well as rapid development spurts. Furthermore, accessible mineral deposits are irregularly distributed

    This paper describes an approach piloted in the Kasserine region of Tunisia to increase the energy efficiency of the distribution of vaccines and temperature sensitive drugs. The objectives of an approach, known as the 'net zero energy' (NZE) supply chain were demonstrated within the first year of operation. The existing distribution system was modified to store vaccines and medicines in the same buildings and to transport them according to pre-scheduled and optimized delivery circuits. Electric utility vehicles, dedicated to the integrated delivery of vaccines and medicines, improved the regularity and reliability of the supply chains. Solar energy, linked to the electricity grid at regional and district stores, supplied over 100% of consumption meeting all energy needs for storage, cooling and transportation. Significant benefits to the quality and costs of distribution were demonstrated. Supply trips were scheduled, integrated and reliable, energy consumption was reduced, the recurrent cost of electricity was eliminated and the release of carbon to the atmosphere was reduced. Although the initial capital cost of scaling up implementation of NZE remain high today, commercial forecasts predict cost reduction for solar energy and electric vehicles that may permit a step-wise implementation over the next 7-10 years. Efficiency in the use of energy and in the deployment of transport is already a critical component of distribution logistics in both private and public sectors of industrialized countries. The NZE approach has an intensified rationale in countries where energy costs threaten the maintenance of public health services in areas of low population density. In these countries where the mobility of health personnel and timely arrival of supplies is at risk, NZE has the potential to reduce energy costs and release recurrent budget to other needs of service delivery while also improving the supply chain.

    Full Text Available The article presents a computer simulation-based model for analysis of supply chain resilience, which allows determining and verifying the generally valid principles, capabilities and ways for building long-term resilience of global supply chains against serious disruptions. The model is created on the basis of a supply chain from automotive industry and contains the main logistics flows used by present automotive producers. Any real automotive supply chain can be modelled as a combination of these logistics flows. The model was created in DOSIMIS-3® and verified using experimental data. The performed simulation demonstrates a significant decrease of the supply chain performance in case of serious disruption occurrence.

  14. SUPPLY CHAIN MANAGEMENT – KEY FACTORS

    Directory of Open Access Journals (Sweden)

    Magdalena Daniela DINU

    2014-06-01

    Full Text Available This paper exposes Supply Chain Management by its key factors. Briefly, where the Supply Chain Management is treated as strategic part of a company then maintaining both control and influence throughout the entire supply chain are key factors and critical to success. On the other hand, finding the right partner to manage the non-strategic Supply Chains would be another key factor too. To define the most important key factors within Supply Chain Management means a deeply understanding of both Supply Chain’ s components, procedures, workflow, processes and the importance of Supply Chain Management into maximizing company's value. SCORE model able to provide solid information about measuring performance and identifying priorities within Supply Chain Management will help us to understand the key factors by analyzing its elements: Plan, Source, Make, Deliver,Return, Enable. These elements covers all the challenging areas from first to third tier of Supply Chain Management.

  15. What is a Responsible Supply Chain?

    Directory of Open Access Journals (Sweden)

    Terje Ingebrigt Vaaland

    2012-02-01

    Full Text Available The paper introduces the concept of responsible supply chain based on two dimensions, the core processes of a supply chain and the concept of corporate social responsibility (CSR. It is suggested that a responsible supply chain is achieved through manifested core values of the supply chain actors, strategies, and tactics. The paper further discusses the individual supply chain actors’ responsibility in securing a responsible supply chain beyond the actors’ direct control. A conceptual model and a definition of a responsible supply chain are offered. Our model not only provides structure to the extant research but also develops new constructs and relationships that improve the conceptualization of the responsible supply chain. The paper is based on a review of 81 research articles published between 2000 and 2010 in which elements of CSR and supply chain processes are included.

    Berry, J. K.; Sailor, J.

    1982-01-01

    The structure of a computer-oriented cartographic model for assessing roundwood supply for generation of base load electricity is discussed. The model provides an analytical procedure for coupling spatial information of harvesting economics and owner willingness to sell stumpages. Supply is characterized in terms of standing timber; of accessibility considering various harvesting and hauling factors; and of availability as affected by ownership and residential patterns. Factors governing accessibility to timber include effective harvesting distance to haulic roads as modified by barriers and slopes. Haul distance is expressed in units that take into account the relative ease of travel along various road types to a central processing facility. Areas of accessible timber are grouped into spatial units, termed 'timbersheds', of common access to particular haul road segments that belong to unique 'transport zones'. Timber availability considerations include size of ownership parcels, housing density and excluded areas. The analysis techniques are demonstrated for a cartographic data base in western Massachusetts.

  20. Reprivatizing pharmaceutical supplies in Africa.

    Science.gov (United States)

    Turshen, M

    2001-01-01

    Perhaps no part of the health system is as imperiled by neoliberal economic reforms as the public drug sector. The national bill for pharmaceuticals can claim one-third of a developing country's annual health budget. This article describes the essential drugs program created by WHO in the 1980s to protect financially reduced ministries of health from the high prices charged by multinational pharmaceutical companies. It describes the backlash from the World Bank and UNICEF, which launched the Bamako Initiative and other community financing schemes and revolving drug plans in which individuals, families or community groups buy drugs above the wholesale purchase price; clinics use the proceeds to maintain drug supplies and subsidize other health services. When this plan failed, the Bank proposed outright privatization of drug purchase and supply, returning power to the multinational suppliers. The article ends with a consideration of patents and the new intellectual property rights as they pertain to pharmaceutical production in Africa. PMID:11469153

  1. Indemnification of the quality of water supply in residential areas

    Institute of Scientific and Technical Information of China (English)

    CHENJing; GUOShiquan

    2003-01-01

    Most cities of our country now adopt the method of concentative pipe nets in water supply. In order to meet the users'' request of hydraulic pressure, some small residential areas or building groups have established water supply systems of secondary compression. Now most water supply enterprises do much work in purification processes of waterworks so as to improve the water quality; however, the secondary pollution because of water supply pipe nets is ignored. An investigation was done by special team of “security technology of water quality in residential areas” and they investigated water quality of waterworks and health and quarantine stations in big and middle cities of the whole country. The result indicates that secondary pollution of pipeline networks indeed exists. So, in order to resolve the question of secondary pollution and to provide people with clean and secure drinking water, the reason that secondary pollution came into being must be understood, moreover, concrete methods and measures aimed at each reason should be found out.

  3. Non-OPEC oil supply

    International Nuclear Information System (INIS)

    The concentration of world oil reserves in members of the Organization of the Petroleum Exporting Countries (OPEC) has resulted in directing most of the attention toward them. Analysts in energy and petroleum place particular emphasis on developments within these countries. This emphasis is well placed and justified if the scope of the study is long term. However, it would be imprudent to minimize the role of non-OPEC producers in the world petroleum market if the scope of the study is short or medium term. The profiles of production in these countries assume particular importance in assessing market equilibrium and the resulting price pattern. Moreover, development since the early 1980s proved the resilience of production in non-OPEC nations and their ability to maintain production despite a substantial price decline. In fact, some of the countries were able to expand their output despite the decline in prices. In order to analyze this phenomenon, the present paper attempts to utilize available data to estimate an aggregate supply function for the non-OPEC producers as well as a separate supply function for the U.K. North Sea region. The objective is to assess the shape of the supply function and to get reliable estimates of the supply elasticity. The next section outlines the profiles of reserves and production in both OPEC and non-OPEC countries. Thereafter, the data and the estimation method are discussed. The subsequent fourth section presents the results of the estimation, followed by a summary and conclusions. 2 figs., 4 tabs

    The paper develops a theoretical framework, and a diagrammatic apparatus, for explaining the supply of child labour. It examines the effect of credit, insurance, and poverty (defined as more than just low income). It also explains bonded child labour, a modern form of slavery closely associated with the worst forms of child exploitation. The analysis is positive, but provides some of the elements for a normative judgement.

  10. Radon in ground water supplies

    International Nuclear Information System (INIS)

    In September 1986, the System Water Quality Department of the American Water Works Service Co. began conducting a radon survey that was designed to determine the levels of radon in American ground water supplies, and to assess the radon removal efficiency of existing treatment processes such as filtration through granular activated carbon (GAC) and various forms of aeration. The survey found that companies in the northeastern part of the country experienced the highest levels of radon in ground water supplies. The highest concentrations were in individual wells in New Hampshire, Maryland, Connecticut, Rhode Island, New Jersey, Pennsylvania and California. The analytical results from the occurrence phase of the survey seemed to correlate well with the known geology of the aquifer materials from which samples of ground water were drawn. The highest levels were associated with formations of uranium-bearing granitic rocks. GAC can effectively reduce radon concentrations in drinking water supplies to very low levels. However, the amount of contact time within the carbon bed required to do so would be prohibitive to many water utilities from an operational and economic standpoint. Further, disposal of the spent GAC as a low-level radioactive waste may be required. Aeration is very effective in the removal of radon from drinking water. Packed tower aerators achieved > 95% reduction in radon concentrations and conventional cascading tray aerators achieved > 75% reduction in radon concentrations. 7 refs., 6 tabs

  11. Foreign uranium supply. Final report

    International Nuclear Information System (INIS)

    This report presents an assessment of the extent to which foreign uranium may be available to United States utilities in the short term (through 1980), the intermediate term (1981--1985), and the long term (1986--95). All free world foreign uranium producers and prospects are included, with particular emphasis on Australia, Canada, southern Africa, France, and French-speaking Africa. The assessment includes reserves, resources, exploration and prospects; firm and potential production capacity and prospects; national policies and relevant political and economic conditions; foreign uranium demand; etc. Conclusions are: Foreign supply capability is greater than foreign demand in the near term. The current availability of uncommitted future Australian production presents an unusual opportunity for establishing commercial relations with very substantial producers. Foreign uranium contracts represent an increase in diversity of supply and access to resources but have less assurance of supply than do domestic contracts. However, uncertainties can frequently be accommodated within an overall procurement program, thereby retaining the diversity and price advantages of foreign procurement. The practice of market pricing of contracts reduces the incentives for foreign contracting

  12. TFTR CAMAC power supplies reliability

    International Nuclear Information System (INIS)

    Since the expected life of the Tokamak Fusion Test Reactor (TFTR) has been extended into the early 1990's, the issues of equipment wear-out, when to refurbish/replace, and the costs associated with these decisions, must be faced. The management of the maintenance of the TFTR Central Instrumentation, Control and Data Acquisition System (CICADA) power supplies within the CAMAC network is a case study of a set of systems to monitor repairable systems reliability, costs, and results of action. The CAMAC network is composed of approximately 500 racks, each with its own power supply. By using a simple reliability estimator on a coarse time interval, in conjunction with determining the root cause of individual failures, a cost effective repair and maintenance program has been realized. This paper describes the estimator, some of the specific causes for recurring failures and their correction, and the subsequent effects on the reliability estimator. By extension of this program the authors can assess the continued viability of CAMAC power supplies into the future, predicting wear-out and developing cost effective refurbishment/replacement policies. 4 refs., 3 figs., 1 tab

  13. The German power supply situation

    International Nuclear Information System (INIS)

    The first key statement of this paper runs like this: The situation of power supply in Germany basically is good. However, two qualifications should be added: The current situation is still good. Power outages as a consequence of power plant failures of the kind experienced in other countries must not be expected to occur in Germany. German utilities work hard to offer this assurance also for the future. This is where politics comes in with the need to guarantee reliable framework conditions. After deregulation of the electricity market, reregulation resulting from government interventions is becoming potentially more and more problematic. Energy issues remain at the top of the political agenda, e.g. with the amendment to the Power Economy Act. This is a matter involving a variety of questions and projects on the part of legislators which require delicate handling because, in addition to the prices to be paid by consumers, they also involve as the most important factor the continuity of supply. Nuclear power today covers a major part of our baseload supply, in addition to lignite and hard coal which are used mainly in the medium-load range. Supported by the findings of recent studies, such as the dena Study, the Prognos and EWI Energy Report, the problem is how to replace this share reliably, in a way protecting the climate and economically viable, in line with the political conditions stipulating residual electricity outputs of nuclear power plants. Other countries can be seen to pursue different policies in using nuclear power. (orig.)

    2015-06-01

    Full Text Available A building code, or building control, is a set of rules that specify the minimum standards for constructed objects such as buildings and non building structures. The main purpose of building codes are to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate governmental or private authority. Building codes are generally intended to be applied by architects, engineers, constructors and regulators but are also used for various purposes by safety inspectors, environmental scientists, real estate developers, subcontractors, manufacturers of building products and materials, insurance companies, facility managers, tenants and others.

  15. Energy efficiency criteria in uninterruptible power supply selection

    International Nuclear Information System (INIS)

    With the generalized use of microelectronic devices, server computers and other susceptible equipment, the subject related to power quality (PQ) and its relationship to vulnerability of high performance plants are becoming an increasing concern to the industry. This paper addresses how uninterruptible power supply (UPS), particularly when configured in distributed DC mode, can become an energy efficient (EE) solution in high-tech buildings, especially when integrated with complimentary PQ measures. The paper is based on PQ audits conducted at different high-tech industries over the last years. It was found that the main problems for the equipment installed were voltage sags (or dips). Among all categories of electrical disturbances, voltage sags and momentary interruptions are the nemeses of the automated industrial process. The paper analyzes the capabilities of modern electronic power supplies and the convenience of embedded solution. Finally it is addresses the role of the Standards on the protection of electronic equipment and the implications for the final costumer.

    Energy Technology Data Exchange (ETDEWEB)

    Hartley, M.J.; Nerlove, M.; Peters, R.K. Jr.

    1987-11-01

    An analysis of the supply response for perennial crops is undertaken for rubber in Sir Lanka, focusing on the uprooting-replanting decision and disaggregating the typical reduced-form supply response equation into several structural relationships. This approach is compared and contrasted with Dowling's analysis of supply response for rubber in Thailand, which is based upon a sophisticated reduced-form supply function developed by Wickens and Greenfield for Brazilian coffee. Because the uprooting-replanting decision is central to understanding rubber supply response in Sri Lanka and for other perennial crops where replanting activities dominate new planting, the standard approaches do not adequately capture supply response.

  19. Electricity supply in Sweden 1982

    International Nuclear Information System (INIS)

    Energy consumption decreased from 31.1 Mtoe in 1981 to 30.4 Mtoe in 1982 . Most of this decrease occured in industry. The supply of fuel to Sweden decreased supply of electricity for heating. Electricity supply of elctricity increased from 97.4 TWh in 1981 to 99.9 TWh in 1982. Electricity consumption increased during 1982 by 2.6 percent. This was mainly due to an increase in the use of electricity for heating. Electricity consumption in industry has remained unchanged since 1973. Hydro power accounted for 52.9 percent and nuclear power for 36.4 percent of the total supply of electricicity in 1982. The highest hourly load during 1982 and amounted to 19263 MW. The lowest load during 1982 and amounted to 5043 MW. Nine nuclear power units were in commercial operation during the year. A further unit, Ringhals 4, was in trial operation part of the time and supplied power to the grid system. The energy availability figures were as follows: Barsebaeck 1 83 percent, Barsebaeck 2 96 percent, Forsmark 1 76 percent, Forsmark 2 67 percent, Oskarshamn 1 78 percent, Oskarshamn 2 88 percent, Ringhals 1 78 percent and Ringhals 2 66 percent. The production of electricity from conventional thermal power stations was only 5.1 TWh. Back pressure power in industry contributed 2.5 TWh of this figure and combined power and district heating stations 2.3 TWh. 30 km of 400 kV line and 39 km of 220 kV line were added to the high voltage power network during 1982. The combined line length in the high voltage power network now amounts to 14342 km. The high voltage power grid system permits joint operation by all the power companies in the country and the major power companies can also utilize the network for exchanging surplus power with other power companies. An account of the public debate on energy in Sweden during 1982 is also given.(author)

  20. The potential market for PV building products

    International Nuclear Information System (INIS)

    This study was carried out by ECOTEC Research and Consulting Limited (ECOTEC) in collaboration with the Newcastle Photovoltaic Application Centre (NPAC) and ECD Energy and Environment (ECD) under the Department of Trade and Industry's (DTI) New and Renewable Energy Programme (contract reference S/P2/00277/00/00). The aim was to assess the future market potential for building-integrated photovoltaic (BIPV) products in terms of current product availability, product development needs, the nature and size of the potential market, and the opportunities for government and the PV supply industry to work together to develop the market. The study itself comprised a review of existing BIPV products, an analysis of the development of the world market for BIPV, a market research survey of building professionals, and meetings of two 'focus groups' drawn from the PV 'supply side' and from buildings professionals. In principle, BIPV products can be used in virtually any type of building, but the main applications are considered to be housing and offices. (author)

    Full Text Available Problem statement: In today’s manufacturing world, globalization policies and rejuvenation have created a more intensive competition amongst manufacturers. On the other hand, manufacturers have turned to the option of adopting innovative technologies, process re-engineering and strategies such as efficient supply chain management to achieve a sustainable competitive advantage. Effective supply chain performance measurement has been identified as a key issue towards efficient supply chain management. To explore the extent of research in supply chain performance measurement and establish the gap in knowledge in supply chain performance measurement using fuzzy logic operation. Approach: Literatures in the area of supply chain performance measurement had been extensively reviewed. Both traditional and fuzzy logic approaches to supply chain performance measurement were scrutinized. Further scrutiny was carried out to establish potential research areas in the application of fuzzy logic operations in supply chain performance measurement. Results: The supply chain performance measurement using fuzzy logic operation was identified as a new direction in measuring the uncertainty and ambiguity surrounding supply chain performance measurement. Direction for further studies in the application of fuzzy logic operation in supply chain management and its performance measurement were also identified. Conclusion: Result of this study implied that there is still a gap in knowledge in the area of supply chain performance measurement. This new direction of studies involved extending the existing supply chains to incorporate product recovery after the useful life.

    Managing the supply chain plays an important role in creating competitive advantages for companies. Adequate information flow in supply chain is one of the most important issues in SCM. Therefore, using certain Information Systems can have a significant role in managing and integrating data and information within the supply chain. Pharmaceutical supply chain is more complex than many other supply chains, in the sense that it can affect social and political perspectives. On the other hand, managing the pharmaceutical supply chain is difficult because of its complexity and also government regulations in this field. Although, Iran has progressed a lot in pharmaceutical manufacturing, still there are many unsolved issues in managing the information flow in the pharmaceutical supply chain. In this study, we reviewed the benefits of using different levels of an integrated information system in the supply chain and the possible challenges ahead. PMID:26664401
