    1981-01-01

    If the Three Mile Island (TMI) unit 1 returns to service, state ownership with a Regional Power Authority to oversee its operation and complete the cleanup of unit 2 would benefit ratepayers and avoid lengthy lawsuits, according to an Arthur Young and Company report to the New Jersey Board of Utilities. The report rejects continued ownership by General Public Utilities (GPU), merger, divestiture, and other options. It also outlines several conditions necessary for a Regional Power Authority: adequate rate relief, restart of TMI-1, congressional tax exemption, and approval by the GPU board and stockholders. The report recommends that Jersey Central divest itself of GPU to avoid financial disaster if GPU should declare bankruptcy, but it advises maintaining the flexibility to exercise long-term options

  5. Three run-of-river power plants

    International Nuclear Information System (INIS)

    1992-01-01

    Three 'run-of-river' hydroelectric power plants in the Montreal area in the province of Quebec were described visually and in sound. A run-of-river generating station is one that has no reservoir behind the generating facilities. Instead of a reservoir, the generating station draws its power from the strong flow of the whole river as it passes through the turbines. The first generating station described was the Beauharnois power plant completed in 1963 which became the most powerful generating station in Canada at that time. Today, it ranks fourth after the La Grande complex. In winter, it supplies electricity primarily to the Quebec power system, but between April and November, 90 per cent of its power is destined for export. The Carillon power station on the Ottawa River, the second to be discussed in this videotape presentation, was completed in 1964 with a total generating capacity of 654 MW. Today, it is the tenth largest of its kind in Quebec. The Rivieres des Prairies generating station, the third and last one described was completed in 1930; today it has a generating capacity of 45 MW. Some of the efforts made by Hydro-Quebec to protect and enhance the natural environment were shown in action, including regular removal and recycling of debris at the gateways to the generating stations, construction of fish spawning ladders, and the control of zebra mussels

  6. Agricultural water conservation programs in the lower Colorado River Authority

    International Nuclear Information System (INIS)

    Kabir, J.

    1993-01-01

    Rice irrigation is the largest user of water within the area served by the Lower Colorado River Authority (LCRA), accounting for approximately 75 percent of total annual surface and ground water demands. In an average year, about 30 percent of surface water supplied to rice irrigation is satisfied with water released from the storage in the Highland Lakes located at the upstream reaches of the Lower Colorado River and its tributaries. During a severe drought, the demand for stored water could be as much as 70 percent of annual rice irrigation demand. LCRA owns and operates two irrigation canal systems which together supply water to irrigate 60,000 acres of rice each year. These irrigation systems are the Lakeside and Gulf Coast Irrigation Divisions. The Lakeside system is located in Colorado and Wharton Counties and the Gulf Coast system is located in Wharton and Matagorda Counties. In the 1987 and 1989, the Lower Colorado River Authority Board of Directors authorized implementation and funding for Canal Rehabilitation Project and Irrigation Water Measurement Project respectively. These two projects are key initiatives to agricultural water conservation goals established in the LCRA Water Management Plan and Water Conservation Policy. In addition LCRA participated actively in agricultural water conservation research projects and technology transfer activities

    1984-03-01

    During the past four decades, a number of water power plants has been put up along the river Lech between Fuessen to Augsburg; this section being under the concession of BAWAG. With the present report, the author shows how and by what means water power plants can be designed ecologically beneficial, and he furthermore demonstrates that modern technics and conservation of environment are very well compatible with each other. The use of water power as an indigenous, nonpolluting and constantly regenerating source of energy, also in the future, is pointed out.

    As renewable generation has become less expensive during recent decades, and it becomes more accepted by the global population, the focus on renewable generation has expanded to include new types with promising future applications, such as river and tidal generation. Although the utilization of power electronics and electric machines in industry is phenomenal, the emphasis on system design is different for various sectors of industry. In precision control, robotics, and weaponry, the design emphasis is on accuracy and reliability with less concern for the cost of the final product. In energy generation, the cost of energy is the prime concern; thus, capital expenditures (CAPEX) and operations and maintenance expenditures (OPEX) are the major design objectives. This paper describes the electrical power conversion aspects of river and tidal generation. Although modern power converter control is available to control the generation side, the design was chosen on the bases of minimizing the CAPEX and OPEX; thus, the architecture is simple and modular for ease of replacement and maintenance. The power conversion is simplified by considering a simple diode bridge and a DC-DC power converter to take advantage of abundant and low-cost photovoltaic inverters that have well-proven grid integration characteristics (i.e., the capability to produce energy with good power quality and control real power and voltage on the grid side).

    2009-07-01

    Ontario's Grand River Conservation Authority (GRCA) is a corporate body, through which municipalities, landowners and other organizations work cooperatively to manage the watershed and outdoor recreation. This involves reducing flood damage; improving water quality; providing adequate water supply; protecting natural areas; watershed planning; and environmental education. This presentation discussed public safety issues regarding a dam in the GRCA that is 5 minutes to downtown Brantford; 5 minutes to several elementary and secondary schools; and a popular area for anglers. The city of Brantford owns the east embankment and the Brant conservation area is located on the west embankment. The safeguards included measures to involve the municipality and local police; install better signage; install better fencing; and public education. Increasing public awareness of the dangers surrounding dams was an important point of the presentation. Results included reduced trespassing and greater community awareness. figs.

    Renewable energy sources are the second largest contributor to global electricity production, after fossil fuels. The integration of renewable energy continued to grow in 2014 against a backdrop of increasing global energy consumption and a dramatic decline in oil prices during the second half of the year. As renewable generation has become less expensive during recent decades, and it becomes more accepted by the global population, the focus on renewable generation has expanded from primarily wind and solar to include new types with promising future applications, such as hydropower generation, including river and tidal generation. Today, hydropower is considered one of the most important renewable energy sources. In river and tidal generation, the input resource flow is slower but also steadier than it is in wind or solar generation, yet the level of water turbulent flow may vary from one place to another. This report focuses on hydrokinetic power conversion.

  20. Hydro-electric power project on the Toulnustouc River

    International Nuclear Information System (INIS)

    Rochon, Y.; Morneau, J.; Lefebvre, G.

    2001-01-01

    Hydro-Quebec has proposed the development of a hydro-electric power project on the Toulnustouc River, located between Saint-Anne Lake and Manic Reservoir. The work would involve the construction of a power generation plant of 526 MW, construction of a 77 m dam on the Toulnustouc River, 14 km downstream from the existing Lac-Saint-Anne dam, the creation of a new water expanse covering 22 square kilometers, the construction of an embankment, the strengthening of the existing Saint-Anne embankment, digging a 9.8 km gallery, and the construction of a flood spillway. This work would have consequences for three different sectors of the river: between the existing and the proposed dam, between the dam and the projected power plant, and between the power plant and the limit of the influence of the reservoir Manic-2. Hydro-Quebec would like the work to begin in July 2001, with the aim of having the plant in operation in 2005. The overall cost of the project is estimated at 600 million dollars. It is expected that the economic benefits for the region would be in the 211 million dollar range. An environmental assessment of the entire project was performed by Quebec Ministere de l'Environnement. The authors determined that the project was recognized as justified by the Ministere des Ressources Naturelles (Natural Resources Ministry) and concluded that the project was acceptable from an environmental point of view as long as six conditions were met. They touched on the construction of a flood spillway capable of evacuating 19 cubic meters per second at any time during the year, that water be evacuated downstream following a pre-determined debit that varies according to the time of year, monitoring of the brook trout population and its habitat, and environmental monitoring. 46 refs., 7 tabs., 2 figs., 1 annex

  3. The interdependence of power, authority and the type of leadership

    Directory of Open Access Journals (Sweden)

    Inić Branimir P.

    2014-01-01

    Full Text Available The terms 'leadership' and 'the leader' are some of the most used words in the business world, often in disregard of their true meaning. Many management theorists believe that the skills and the knowledge of the person who lead the company and from which derives its power and authority are crucial for company's survival, development and growth. It is known that the power is a potential ability to influence the behavior of others and this is one of the main characteristics of leaders. Theoretically speaking the leader's power comes from the position which he occupies in the organization and from which derives its authority. Managers/leaders can achieve the power by using multiple sources of power and various forms and tactics based on power. The authority is a type of power that can be identified as a legitimate, official or a formal type of power. This means that such power occurs when subordinates recognize that someone has that 'right' or the law authorizes him to affect to some extent. In addition, the authority is a form of power that is generally used in a broad sense and includes the ability of people to use the power arising from their skills or their role.

  4. SEXUAL HARASSMENT, WORKPLACE AUTHORITY, AND THE PARADOX OF POWER

    McLaughlin, Heather; Uggen, Christopher; Blackstone, Amy

    2012-01-01

    Power is at the core of feminist theories of sexual harassment, though it has rarely been measured directly in terms of workplace authority. While popular characterizations portray male supervisors harassing female subordinates, power-threat theories suggest that women in authority may be more frequent targets. This article analyzes longitudinal survey data and qualitative interviews from the Youth Development Study (YDS) to test this idea and to delineate why and how supervisory authority, gender non-conformity, and workplace sex ratios affect harassment. Relative to non-supervisors, female supervisors are more likely to report harassing behaviors and to define their experiences as sexual harassment. Sexual harassment can serve as an “equalizer” against women in power, motivated more by control and domination than by sexual desire. The interviews point to social isolation as a mechanism linking harassment to gender non-conformity and women’s authority, particularly in male-dominated work settings. PMID:23329855

  6. Potential role of power authorities in offshore wind power development in the US

    International Nuclear Information System (INIS)

    Dhanju, Amardeep; Firestone, Jeremy; Kempton, Willett

    2011-01-01

    This article examines how power authorities could facilitate and manage offshore wind power development in US coastal waters. The power authority structure is an American 20th century institution for managing energy resources-a form of a public authority or public corporation dedicated to creating, operating and maintaining electric generation and transmission infrastructure. Offshore wind power is characterized by high capital costs but no fuel costs and thus low operating costs. Therefore a power authority, by virtue of its access to low-cost capital and managerial flexibility, could facilitate offshore wind power development by reducing financial risk of developing and lowering debt payments, thus improving the risk profile and lowering the cost of electricity production. Additionally, power authorities can be made up of multiple states, thus opening the possibility for joint action by neighboring coastal states. Using primary and secondary data, we undertake an in-depth analysis of the potential benefits and shortcomings of a power authority approach. - Highlights: → Proposes an institutional solution in the form of power authority for offshore wind power. → Power authority structure can significantly lower the cost of capital. → Tax-free bond financing available to power authority can significantly reduce the cost of energy. → It can enhance regional collaboration among coastal states to harness the offshore wind potential.

    Thermal pollution from power plants degrades riverine ecosystems with ramifications beyond the natural environment as it affects power supply. The transport of thermal effluents along river reaches may lead to plant-to-plant interferences by elevating condenser inlet temperatures at downstream locations, which lower thermal efficiencies and trigger regulatory-forced power curtailments. We evaluate thermal pollution impacts on rivers and power supply across 128 plants with once-through cooling technologies in the Mississippi River watershed. By leveraging river network topologies with higher resolutions (0.05°) than previous studies, we reveal the need to address the issue in a more spatially resolved manner, capable of uncovering diverse impacts across individual plants, river reaches and sub-basins. Results show that the use of coarse river network resolutions may lead to substantial overestimations in magnitude and length of impaired river reaches. Overall, there is a modest limitation on power production due to thermal pollution, given existing infrastructure, regulatory and climate conditions. However, tradeoffs between thermal pollution and electricity generation show important implications for the role of alternative cooling technologies and environmental regulation under current and future climates. Recirculating cooling technologies may nearly eliminate thermal pollution and improve power system reliability under stressed climate-water conditions. Regulatory limits also reduce thermal pollution, but at the expense of significant reductions in electricity generation capacity. However, results show several instances when power production capacity rises at individual plants when regulatory limits reduce upstream thermal pollution. These dynamics across energy-water systems highlight the need for high-resolution simulations and the value of coherent planning and optimization across infrastructure with mutual dependencies on natural resources to overcome

  11. New York Power Authority`s energy-efficient refigerator program for the New York City Housing Authority - savings evaluation

    Pratt, R.G.; Miller, J.D.

    1997-09-01

    The New York Power Authority (NYPA) and the New York City Housing Authority (NYCHA) are replacing refrigerators in New York City public housing with new, highly energy-efficient models over a five-year period. This report describes the analysis of the energy cost savings achieved through the replacement of 20,000 refrigerators in 1996, the first year of the NYPA/NYCHA program. The NYPA/NYCHA project serves as the lynchpin of a larger program designed to offer energy-efficient appliances to housing authorities across the country. The national program is a partnership between the U.S. Department of Energy (DOE) and the Consortium for Energy Efficiency (CEE). Starting with the 1997 refrigerator contract, this program invites other housing authorities to join NYPA in its volume purchase of energy-efficient refrigerators, at the same price and terms available to NYPA. Through these volume purchases, DOE`s ENERGY STAR{reg_sign} Partnerships program hopes to encourage appliance manufacturers to bring more efficient appliances to the market and to provide volume purchasers with the per-unit price savings of a bulk purchaser. DOE asked the Pacific Northwest National Laboratory (PNNL) to establish a protocol for evaluating the savings achieved with the NYPA refrigerators. That protocol is summarized in this report.

    2014-06-01

    Full Text Available Tax literature acknowledges that trust in authorities and power of authorities, as grassroots dimensions of the “slippery slope framework”, influence compliance behavior. The present material assesses the framework’s main dimensions in the case of the Mediterranean tax climate (i.e., Cyprus, Greece, Italy, Portugal and Spain by a manifold of economic, financial and psychological variables. The proposed rationale, including World Bank governance indicators (government effectiveness, rule of law, regulatory quality, control for corruption as proxies for the framework’s dimensions, analyses of chain base indexes with respect to economic performance (calculations involving GDP per capita, quantitative evaluation of tax compliance burden and cost of taxation (calculations involving Paying Taxes reports, aims at raising awareness among policy makers and citizens about relevance of trust and power for compliance behavior within the Mediterranean tax climate. Multidisciplinary estimations of trust and power may constitute a benchmark for decision makers in appraising the effects generated by the measures countervailing crises and in designing strategies to hinder future undesirable economic bouts.

    Penaz, M.; Wohlgemuth, E.

    1990-01-01

    The impact was investigated of the construction and operation of a hydropower station with two deep valley reservoirs and subsequently of a nuclear power station whose water management is closely associated with the river ecosystem, upon the ichthyocoenosis of the downstream river section. The initial quantitative and species composition of the ichthyocoenosis, being descriptive for the barbel zone community, changed into the community of the salmonid type, characteristic of the trout and grayling zones. This process was spontaneous as well as caused by the activity of fish management. The development of fishery catches in the past 30 years and their changes due to the operation of the power system are also analyzed in detail. After a temporary decrease, the annual mean fishery yields improved significantly in the affected river section, not only in their absolute weights but also in terms of the sport and market value of the fish caught.

    The variation of the quality of river Indus water with respect to the seasonal changes, discharge of water and dilution with the effluents of Lakhra Thermal Power Station (LTPS), has been monitored. The studies were focussed on the river Indus water quality before and after mixing the effluents of the power station. The samples were collected monthly from the representative locations of the river Indus, and analyzed for the residues (total, filterable, non-filterable, volatile and fixed), pH, temperature (air and water), conductance, chloride, hardness, alkalinity, dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD) /sub 5/- nitrate, phosphate, sulfate, ammonia, ammonium, silicates, magnesium, potassium, calcium and sodium. The results have been compared with the permissible limits of ECC (European Economic Community) standards for drinking and surface water. (author)

  15. Axial power monitoring uncertainty in the Savannah River Reactors

    International Nuclear Information System (INIS)

    Losey, D.C.; Revolinski, S.M.

    1990-01-01

    The results of this analysis quantified the uncertainty associated with monitoring the Axial Power Shape (APS) in the Savannah River Reactors. Thermocouples at each assembly flow exit map the radial power distribution and are the primary means of monitoring power in these reactors. The remaining uncertainty in power monitoring is associated with the relative axial power distribution. The APS is monitored by seven sensors that respond to power on each of nine vertical Axial Power Monitor (APM) rods. Computation of the APS uncertainty, for the reactor power limits analysis, started with a large database of APM rod measurements spanning several years of reactor operation. A computer algorithm was used to randomly select a sample of APSs which were input to a code. This code modeled the thermal-hydraulic performance of a single fuel assembly during a design basis Loss-of Coolant Accident. The assembly power limit at Onset of Significant Voiding was computed for each APS. The output was a distribution of expected assembly power limits that was adjusted to account for the biases caused by instrumentation error and by measuring 7 points rather than a continuous APS. Statistical analysis of the final assembly power limit distribution showed that reducing reactor power by approximately 3% was sufficient to account for APS variation. This data confirmed expectations that the assembly exit thermocouples provide all information needed for monitoring core power. The computational analysis results also quantified the contribution to power limits of the various uncertainties such as instrumentation error

Since the turn of the century, power interests surveyed the river's flow, sited dams and promoted development schemes. Fisheries interests, on the other hand, sought to maintain the river as salmon spawning habitat. They questioned the necessity of dams, supported fisheries research and rehabilitation and organized anti-development coalitions. Before the mid-1950s a number of dam projects proceeded on Fraser tributaries and major landslides at Hells Gate modeled the dangers of main stem development. Because of the concerted political lobbying of fisheries groups, the skeptical appraisal of fisheries scientists to development proposals and the legal and political authority of the federal Department of Fisheries and the International Pacific Salmon Fisheries Commission, major dam projects were defeated on the Fraser in the late 1950s. Delayed development on the Fraser helped to spur hydroelectric projects on other rivers in the province; the fish-power problem on the Fraser altered the province's spatial economy of power. Once development began on the Columbia and Peace Rivers, the Fraser was protected by implication. The study combines approaches from environmental history, the history of science and political economy to demonstrate the intersections and interactions between nature, knowledge and society. Research was conducted at eleven archives in Canada and the United States in the papers of organizations, corporations, government departments, politicians, scientists and individuals.

    There is an evident need for monitoring pollutants and/or other conditions in river flows via wireless sensor networks. In a typical wireless sensor network topography, a series of sensor nodes is to be deployed in the environment, all wirelessly connected to each other and/or their gateways. Each sensor node is composed of active electronic devices that have to be constantly powered. In general, batteries can be used for this purpose, but problems may occur when they have to be replaced. In the case of large networks, when sensor nodes can be placed in hardly accessible locations, energy harvesting can thus be a viable powering solution. The possibility to use three different small-scale river flow energy harvesting principles is hence thoroughly studied in this work: a miniaturized underwater turbine, a so-called `piezoelectric eel' and a hybrid turbine solution coupled with a rigid piezoelectric beam. The first two concepts are then validated experimentally in laboratory as well as in real river conditions. The concept of the miniaturised hydro-generator is finally embedded into the actual wireless sensor node system and its functionality is confirmed.

  2. River ice implications related to water power production in Norway

    2009-07-01

    Nearly 99 per cent of the electricity produced in Norway is based on water power. While the period of large power development is over, the current focus lies in developing small hydroelectric power plants. A new market based energy law was implemented in Norway in 1991 to achieve more efficient use of electricity production by means of market forces. Since water regulation influences ice conditions in lakes and rivers, this paper focused on the implications of changes in ice conditions. In Norway, the expected changes in ice conditions are taken into account when issuing permits for water regulations and schemes for water discharge because some waterways are used as winter roads. Follow-up includes both close and long term observations and measurements. The impact of variable price on power was also discussed, with particular reference to ice conditions in cases where water discharge occurs on rivers. This paper summarized selected ice problems and how they have been handled. The paper also included a summary of anticipated climatic changes relevant to ice conditions.

    As renewable generation has become less expensive during recent decades, and it becomes more accepted by the global population, the focus on renewable generation has expanded to include new types with promising future applications, such as river and tidal generation. Although the utilization of power electronics and electric machines in industry is phenomenal, the emphasis on system design is different for various sectors of industry. In precision control, robotics, and weaponry, the design emphasis is on accuracy and reliability with less concern for the cost of the final product. In energy generation, the cost of energy is the prime concern; thus, capital expenditures (CAPEX) and operations and maintenance expenditures (OPEX) are the major design objectives. This paper describes the electrical power conversion aspects of river and tidal generation. Although modern power converter control is available to control the generation side, the design was chosen on the bases of minimizing the CAPEX and OPEX; thus, the architecture is simple and modular for ease of replacement and maintenance. The power conversion is simplified by considering a simple diode bridge and a DC-DC power converter to take advantage of abundant and low-cost photovoltaic inverters that have well-proven grid integration characteristics (i.e., the capability to produce energy with good power quality and control real power and voltage on the grid side).

    2011-01-01

    Using verified and validated reactor physics methods coupled to a currently accepted thermal hydraulic analysis methodology, onset of incipient boiling power agrees well with the currently-accepted safety basis value. The MCNP-based methodology is acceptable for scoping studies of LEU fuel conversion. A balance-of-plant assessment would have to be conducted to determine if the power up-rate to 100 MW could be supported for LEU fuel. While analyses performed 45 years ago have been shown to be in agreement with today s methods, there is an advantage to the current methodology in that people working at HFIR today can explain/justify/defend the safety analyses rather than relying solely on documentation.

  9. Hydroelectric power plant project on the Coulonge River: Report of inquiry and public hearing

    International Nuclear Information System (INIS)

    1992-01-01

    A hydroelectric power plant is proposed for the Coulonge River, a tributary of the Ottawa River in Quebec. Water would be taken from the river through a 609 m tunnel to the plant, which would contain two Francis turbines with a total installed power of 16.2 MW operating under a net head of 43 m and a water flow rate of 21.5 m 3 /s. Other works would be necessary upstream for controlling flow and protecting the intake. Total cost for the two-year construction project is estimated at $28 million and annual revenues are forecast at $6 million. An inquiry and public hearing were held to consider the biophysical, social, economic, and cultural impacts of the proposed hydroelectric project. Results of the hearing are summarized in such areas as legal aspects, environmental quality, water rights, land use, job creation, effects on tourism and recreation, effects on wildlife, water level fluctuations, water quality, and safety. The economic justification for the project is discussed with reference to electricity demand, economic viability, utilization factors, and policies that favor construction of small-scale hydroelectric plants. The project was not found to bring sufficient benefits to the region in which it was to be situated and would not be authorized unless Hydro-Quebec tariff policy with respect to small hydro plants was modified and unless the project sponsor compensates the regional municipality. 13 refs., 11 figs., 4 tabs

  10. Feasibility study for Boardman River hydroelectric power. Final report

    None

    1979-02-22

    The feasibility of generating additional hydroelectric power from five consecutive existing dams located on the Boardman River in Grand Traverse County and Traverse City, Michigan, was investigated. The potential hydropower production capabilities, in terms of base load power and peak load power, the legal-institutional-environmental constraints, and the economic feasibility, including capital investment, operating costs and maintenance costs, were evaluated for each of the five dam sites individually and as a series of co-dependent facilities. The impact of installing fish passages at each site was analyzed separately. The feasibility assessment utilized the present worth analytical method, considering revenue based on thirty mills/kWh for power, 0.4% general economy escalation rate, and a 6% net income to the municipal utility. The sensitivity of fuel costs increasing at a different rate than the general price-escalation was tested by allowing the increase in fuel costs to vary from 3 to 8% per year. Assuming fuel costs increase at the same rate as the general economy, it is feasible to update, retrofit, renovate, and install hydroelectric generating capacity at Sabin, Boardman and Brown Bridge. Rehabilitation of Union Street and Keystone is also feasible but somewhat less attractive. Operating the dams as a co-dependent system has environmental advantages and can provide additional revenue through peak load power rates. A development plan to implement the above is outlined utilizing an ownership arrangement whereby Grand Traverse County provides easements for Sabin and Boardman Dams. The plan calls for operation of the system by Traverse City.

    2014-06-01

    Full Text Available In tax behavior research field, two dimensions compiling the “slippery slope framework” are regarded as main drivers of compliance, i.e., perceived trust in authorities and perceived power of authorities. The former grasps citizens’ cognitions towards the efforts tax authorities render in benevolently supplying public goods. The latter covers general cognitions about authorities’ capacity of detecting and efficiently inflicting punishments on tax dodgers. Following interactions which involve both parties of the tax game, a society’s common good is secured through the ensued tax compliance level. Nevertheless, like any outcome depending on cooperation, compliance is frail. This happens mainly because authorities are called to mediate an ongoing clash between citizens who abide by legal prescriptions, through voluntary or enforced compliance, and citizens who eschew them if opportunities arise, through avoidance or evasion. Depending on the chosen mediation approach (trust-based or power-based, one type of compliance prevails over another. The present writing explores new insights of the framework’s chief dimensions within the perimeter of the Latin American interaction tax climate (viz. Argentina, Brazil, Colombia, Costa Rica, Mexico, Peru by dint of economic, fiscal and psychological determinants. The proposed methodological apparatus ranges from operationalizing World Bank governance indicators (government effectiveness, rule of law, regulatory quality, control for corruption as trust and power proxies, assessing economic growth through chain base indexes and rating ease of tax compliance based on reliable benchmarks (e.g., Paying Taxes indicators, shadow economy, corruption perceptions. The leading goal of the study is to make authorities, investors, international organizations and laypeople cognizant of the role trust in and power of authorities play for compliance levels reached in the Latin American tax climate.

    2007-12-01

    Full Text Available The paper aims to provoke discussion about two issues. Firstly, how do economic ideas, concepts, theories, principles and information enter into the discourse of the owners and controllers of Europe’s most popular sport – football – and into political discussion about the game? It stresses the role management consultants have created for themselves in the new football 'industry'. Secondly, as a specific example of the general concern, the paper considers the role of the Deloitte company in European football. Its publications – especially the Annual Reviews of Football Finance – have been very influential and the company has acted as consultants for UEFA on many of the key issues in contemporary football. The paper critically assesses the approach Deloitte has adopted to the commercialisation of football, and explores difficulties in the way it has analysed some of the key issues in European football. It suggests that some countervailing forces need to be created to limit the authority and influence Deloitte currently exercise.

    Important quantities of ash and breeze resulting from combustion of fossil fuels used in Rovinari, Turceni and Paroseni power plants were evacuated by hydraulic transport into decant ponds for the primary treatment. Waste waters resulting from hydrotransport have large suspension concentrations and, occasionally, strong alkaline pH values. Periodically, accidental pollutions affected the river Jiu and large areas of agricultural lands. The paper presents the analysis results of waste water pH, suspensions and fixed residue. The causes of river Jiu pollution are discussed and measures to reduce its effects are suggested. (authors)

  16. Design basis flood for nuclear power plants on river sites

    International Nuclear Information System (INIS)

    1983-01-01

    The Guide presents techniques for determining the design basis flood (DBF) to be used for siting nuclear power plants at or near non-tidal reaches of rivers and for protecting nuclear power plants against floods. Since flooding of a nuclear power plant can have repercussions on safety, the DBF is always chosen to have a very low probability of exceedance per annum. The DBF may result from one or more of the following causes: (1) Precipitation, snowmelt; (2) Failure of water control structures, either from seismic or hydrological causes or from faulty operation of these structures; (3) Channel obstruction such as landslide, ice effects, log or debris jams, and effects of vulcanism. Normally the DBF is not less than any recorded or historical flood occurrence. For flood evaluation two types of methods are discussed in this Guide: probabilistic and deterministic. Simple probabilistic methods to determine floods of such low exceedance probability have a great degree of uncertainty and are presented for use only during the site survey. However, the more sophisticated probabilistic methods, the so-called stochastic methods, may give an acceptable result, as outlined in this Guide. The preferred method of evaluating the component of the DBF due to precipitation, as described in this Guide, is the deterministic one, based on the concept of a limit to the probable maximum precipitation (PMP) and on the unit hydrograph technique. Dam failures may generate a flood substantially more severe than that due to precipitation. The methodology for evaluating these types of floods is therefore presented in this Guide. Making allowance for the possible simultaneous occurrence of two or more important flood-producing events is also discussed here. The Guide does not deal with floods caused by sabotage

    During the routine operation, nuclear power plants discharge waste water containing a certain amount of radioactivity, whose main component is the artificial radionuclide tritium. The amounts of tritium released into the environment are kept within the legal requirements, which minimize the noxious effects of radioactivity, but the activity concentration is well measurable in surface water of the recipient. This study compares amount of tritium activity in waste water from nuclear power plants and the tritium activity detected at selected relevant sites of surface water quality monitoring. The situation is assessed in the catchment of the Vltava and Elbe Rivers, affected by the Temelín Nuclear Power Plant as well as in the Jihlava River catchment (the Danube River catchment respectively), where the waste water of the Dukovany Nuclear Power Plant is discharged. The results show a good agreement of the amount of released tritium stated by the power plant operator and the tritium amount detected in the surface water and highlighted the importance of a robust independent monitoring of tritium discharged from a nuclear power plant which could be carried out by water management authorities. The outputs of independent monitoring allow validating the values reported by a polluter and expand opportunities of using tritium as e.g. tracer. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Water flow behaviour of Pampeano aquifer was modeled using Visual Mod-flow software Package 2.8.1 with the assumption of a free aquifer, within the region of the Areco river and extending to the rivers of 'Canada Honda' and 'de la Cruz'. Steady state regime was simulated and grid refinement allows obtaining locally detailed calculation in the area of Atucha I and II Nuclear power plants, in order to compute unsteady situations as the consequence of water flow variations from and to the aquifer, enabling the model to study the movement of possible contaminant particles in the hydrogeologic system. In this work the effects of rivers action, the recharge conditions and the flow lines are analyzed, taking always into account the range of reliability of obtained results, considering the incidence of uncertainties introduced by data input system, the estimates and interpolation of parameters used.

    2017-11-01

    Activities of sand mining on the surface stream (river) conducted by Panji Mahakarya company potentially cause various environmental issues. These problems include the destruction of the river ecosystem, decreased the quality of river water quality, increased water pollution load, and another effect on capacity and power support river. The Lambidaro River is one of the rivers found in Palembang, where the inhabitants who live around it take advantage of the existence of this river to meet their daily needs such as bathing, washing, and latrines. The purpose of this research is to know the influence of mining activities towards sustainability of the power support and capacity of the river. The method used in this research is to compare the availability of water and water needs of the population in determining the status of environmental power support based on regulation of the state minister of the environment number 17 in 2009 about the determination of the power guidance support environment in spatial regions, as well as using the index method of pollution based on the decision of the State Minister of the environment number 115 in 2003 about the determination of the status of water quality guidelines with parameters measured are TDS, TSS, pH, DO, COD, dan BOD5. The results of the calculation of the power support river are deficit where SA (34,200,655.64 m3/year) < DA (253,105,600 m3/year). The result of pollution index calculation at 5 water sampling locations shows that the condition of a river is in good condition (uncontaminated) and mild pollutant.

    River diversions are necessary measures in reservoir and river power station construction in order to be able to construct the planned buildings in dry building ground. These diversion measures are only temporary as only in the construction phase of the retaining works the flow is led through the site. As in the recent past large hydraulic engineering plants have reached new dimensions also river diversions have gained importance with regard to the flow to be controlled. With this work the author wants to contribute to an improvement in river diversion with regard to safety, economy and environmental compatibility. (orig.)

    As renewable generation has become less expensive during recent decades, and it becomes more accepted by the global population, the focus on renewable generation has expanded to include new types with promising future applications, such as river and tidal generation. The input variations to these types of resources are slower but also steadier than wind or solar generation. The level of water turbulent flow may vary from one place to another, however, the control algorithm can be adjusted to local environment. This paper describes the hydrokinetic aspects of river and tidal generation based on a river and tidal generator. Although the information given in this paper is not that of an exact generator deployed on site, the data used is representative of a typical river or tidal generator. In this paper, the hydrokinetic and associated electrical controller of the system were not included; however, the focus of this paper is on the hydrodynamic control.

After investigating the most important legal fundamental principles for the authorization of power engineering plants, the Atomic Act and the Federal Immission Protection Act, the author discusses the problems that arise with the application of the authorization procedures. The reasons which can be made responsible for the long running periods of the authorization procedures and therewith of the realization of the site installation work are given. Finally, the author describes and judges the outlines of regulations for large scale furnaces and for the TA-air supplementary clause. (orig.) [de

    1995-11-01

    The System Operation Review (SOR) is a study and environmental compliance process being used by the three Federal agencies to analyze future operations of the system and river use issues. The goal of the SOR is to achieve a coordinated system operation strategy for the river that better meets the needs of all river users. This technical appendix addresses only the effects of alternative system operating strategies for managing the Columbia River system. This appendix discusses the work performed by the SOR Power Work Group. The Power Work Group (PWG) had several major responsibilities: first, to determine the effects of each of the various system operating strategies (SOS) on the Northwest regional power system; second, given these effects, to determine what, if any, actions are required to meet forecasted regional energy consumption; and finally, to estimate the cost for serving the forecasted regional energy consumption. The Northwest regional power system consists of Federal and non-Federal hydroelectric power projects (hydropower or hydro projects) on the main stem of the Columbia and Snake Rivers, numerous smaller hydro projects on other river reaches, and a number of thermal plants (coal, nuclear and combustion turbines)

    Acting as an energy services provider, the New York Power Authority (NYPA) has initiated a long-term project through which 20,000 refrigerators per year will be replaced with the most energy-efficient units possible in apartments managed by the New York City Housing Authority (NYCHA). Using bulk purchasing as an incentive to appliance manufacturers to produce energy-efficient refrigerators suitable for use in apartments, replaced in the first year of the program, which ended in December 1996. These units, kWh per year. Savings were determined by field testing and laboratory testing of 220 existing refrigerators and 56 newly-installed units. In the next program year, a 15.0-cubic-foot Maytag refrigerator, newly-designed in response to bulk purchasing incentives, is being installed. The new unit has a label rating of 437 kWh per year, 31 percent better than 1993 energy standards. Old refrigerators removed from apartments are {open_quotes}demanufactured{close_quotes} in an environmentally-appropriate way and both metals and refrigerants are recovered for reuse.

    2010-01-01

    This paper explores the results and implications of an illustrative application of a sustainability assessment framework in the design and evaluation of a major integrated power system plan. The paper examines the integrated power system plan developed by the Ontario Power Authority in 2007. The basic framework rests on a generic set of evaluation criteria reflecting basic requirements for progress towards sustainability that was adopted, reinterpreted and applied by the Authority in support of its proposed plan. In response to evident deficiencies in the Authority's work, the authors and colleagues undertook a re-examination using a more fully elaborated sustainability assessment framework, specified for application to power system planning. The results point to a plan and plan components substantially different from those proposed by the Authority. More generally, the results highlight three advantages of applying such a sustainability assessment framework: comprehensive coverage of key requirements for progress towards sustainability while ensuring careful attention to the context and concerns of the sector; emphasis on identifying plan options that avoid major trade-offs among the sustainability criteria and recognition of interactions among the social, ecological, economic and technological realms favouring options that offer multiple, mutually reinforcing and lasting benefits.

  12. Impact of nuclear power plants of the PWR-type on river water quality (case-report of the river Meuse)

    1982-01-01

    Five years' experience with data of the TAILFER plant located 48 km downstream of the nuclear power site of CHOOZ is reported so as to provide guidelines for the examination of future nuclear cases. The factors considered are: the reduction in water flow and thermal impacts, the discharge of nuclear active effluents and the physico-chemical impact of enrichment in salts and suspended matter. Primary importance must be given to the proportion of the discharges in terms of added (instantaneous) volume activities. In the case of inland rivers the most active effluents, including the particular isotope tritium, are contained in a reduced volume (1400 m 3 /1000 MWe), and are best evacuated to other sites. Guidelines to check the river water quality are based on the measurement of 3H, total γ, and specifically, Co 60 , Cs 137 , Mn 54 , Co 58 , and Cs 134 . Flow measurement and river transfer modelling must be part of the study of the impact as illustrated by this case-report. (author)

  13. DELIMITATION OF THE DISCRETIONARY POWER FROM THE POWER EXCESS IN THE ACTIVITY OF THE STATE’S AUTHORITIES

    Directory of Open Access Journals (Sweden)

    MARIUS ANDREESCU

    2012-05-01

    Full Text Available A problem of essence of the lawful state is to delimitate the discretionary power and respectively, the abuse ofright in the state’s institutions activities. The legal behavior of the state institutions is being materialized by their right of appreciation, and the power excess yields in the violation of a subjective right or a legitimate interest of the citizen. The application and observance of the lawfulness principle in the activity of the state authorities is a complex problem because the exercise of the state’s functions assumes the discretionary power with which the state’s organs are invested with, or otherwise said the ‘right of appreciation” of the state’s authorities regarding the moment of adopting and the contents of the disposed measures. The discretionary power cannot be opposed to the lawfulness principle, as a dimension of the lawful state. In this study we propose ourselves to analyze the discretionary power concepts and respectively, the excess of power, having as landmark the legislation, jurisprudence and the doctrine in the matter. At the same time, we wish to identify the most important criterions that will allow the practitioner, no matter whether he / she is an administrator, a public clerk or a judge, to delimit the legal behavior of the state’s institutions from the power excess. In this regard, we appreciate that the principle of proportionality represents such a criterion. We consider that the law courts, by applying the principle of Constitution’s supremacy, can censor some juridical acts contrary to the constitutional norms, if the Lawmaker does not foresee the competence of the Constitutional Court in this matter. In our opinion, all law courts, within the limits of the competence granted by law, can control and censor the juridical acts of some public authorities issued by power excess. In order to demonstrate these assertions some theoretical and juridical practice arguments are being brought.

  14. Hydro-economic performances of streamflow withdrawal strategies: the case of small run-of-river power plants

    2014-05-01

    River flows withdrawals to supply small run-of-river hydropower plants have been increasing significantly in recent years - particularly in the Alpine area - as a consequence of public incentives aimed at enhancing energy production from renewable sources. This growth further raised the anthropic pressure in areas traditionally characterized by an intense exploitation of water resources, thereby triggering social conflicts among local communities, hydropower investors and public authorities. This brought to the attention of scientists and population the urgency for novel and quantitative tools for assessing the hydrologic impact of these type of plants, and trading between economic interests and ecologic concerns. In this contribution we propose an analytical framework that allows for the estimate of the streamflow availability for hydropower production and the selection of the run-of-river plant capacity, as well as the assessment of the related profitability and environmental impacts. The method highlights the key role of the streamflow variability in the design process, by showing the significance control of the coefficient of variation of daily flows on the duration of the optimal capacity of small run-of-river plants. Moreover, the analysis evidences a gap between energy and economic optimizations, which may result in the under-exploitation of the available hydropower potential at large scales. The disturbances to the natural flow regime produced between the intake and the outflow of run-of-river power plants are also estimated within the proposed framework. The altered hydrologic regime, described through the probability distribution and the correlation function of streamflows, is analytically expressed as a function of the natural regime for different management strategies. The deviations from pristine conditions of a set of hydrologic statistics are used, jointly with an economic index, to compare environmental and economic outcomes of alternative plant

  15. Ecology of Legionella within water cooling circuits of nuclear power plants along the French Loire River

    2012-01-01

    The cooling circuits of nuclear power plants, by their mode of operating, can select thermophilic microorganisms including the pathogenic organism Legionella pneumophila. To control the development of this genus, a disinfection treatment of water cooling systems with monochloramine can be used. To participate in the management of health and environmental risks associated with the physico-chemical and microbiological modification of water collected from the river, EDF is committed to a process of increasing knowledge about the ecology of Legionella in cooling circuits and its links with its environment (physical, chemical and microbiological) supporting or not their proliferation. Thus, diversity and dynamics of culturable Legionella pneumophila were determined in the four nuclear power plants along the Loire for a year and their links with physico-chemical and microbiological parameters were studied. This study revealed a high diversity of Legionella pneumophila subpopulations and their dynamic seems to be related to the evolution of a small number of subpopulations. Legionella subpopulations seem to maintain strain-specific relationships with biotic parameters and present different sensitivities to physico-chemical variations. The design of cooling circuits could impact the Legionella community. The use of monochloramine severely disrupts the ecosystem but does not select biocide tolerant subpopulations. (author)

    2015-01-01

    Tax compliance represents a social dilemma in which the short-term self-interest to minimize tax payments is at odds with the collective long-term interest to provide sufficient tax funds for public goods. According to the Slippery Slope Framework, the social dilemma can be solved and tax compliance can be guaranteed by power of tax authorities and trust in tax authorities. The framework, however, remains silent on the dynamics between power and trust. The aim of the present theoretical paper is to conceptualize the dynamics between power and trust by differentiating coercive and legitimate power and reason-based and implicit trust. Insights into this dynamic are derived from an integration of a wide range of literature such as on organizational behavior and social influence. Conclusions on the effect of the dynamics between power and trust on the interaction climate between authorities and individuals and subsequent individual motivation of cooperation in social dilemmas such as tax contributions are drawn. Practically, the assumptions on the dynamics can be utilized by authorities to increase cooperation and to change the interaction climate from an antagonistic climate to a service and confidence climate.

  19. TAXPAYERS AND TAX AUTHORITIES INTERACTING WITHIN THE MENA REGION: THE NEXUS BETWEEN TRUST, POWER AND COMPLIANCE

    Directory of Open Access Journals (Sweden)

    Batrancea Larissa

    2014-12-01

    Full Text Available Any type of interaction climate, be it synergistic or antagonistic, is delineated by a tandem of dimensions: trust in authorities and power of authorities. Advocates for this assumption are the manifold of empirical studies testing the “slippery slope framework” which subsumes the two dimensions. A major proffer advanced by the framework is that tax authorities’ approach towards citizens poses great influence on compliance, either fuelling or hindering it. Irrespective of whether tax burden level is high (e.g., Scandinavian, Continental welfare states, medium (e.g., East European, Anglo-Saxon welfare states, minimum or completely lacking (e.g., tax havens, tax authorities and taxpayers establish a connection in which the former’s actions are mirrored in the latter’s perceptions about leadership’s benevolence in public good provisions (i.e., trust and efficiency in deterring tax evasion (i.e., power. The tandem trust-power and the specific features of such connections within some countries of the Middle East and Northern Africa tax climate (i.e., Bahrain, Egypt, Iran, Jordan, Kuwait, Morocco, Oman, Qatar, Saudi Arabia, United Arab Emirates are the thrust of the present study. The methodology spans a multidisciplinary approach, from explaining trust and power via governance indicators proposed by the World Bank, investigating economic development with chain base indexes and examining tax compliance process on country-level. The MENA region is source for novel and relevant insights on the nexus between trust, power and compliance, as it hosts countries which vary greatly in terms of economic development (transition to developed, fiscal policy (low to no taxes or economy drivers (oil exporters, oil importers and where tax compliance gains importance amid diminishing hydrocarbon resources.

  2. Power learning or path dependency? Investigating the roots of the European Food Safety Authority.

    Roederer-Rynning, Christilla; Daugbjerg, Carsten

    2010-01-01

    A key motive for establishing the European Food Safety Authority (EFSA) was restoring public confidence in the wake of multiplying food scares and the BSE crisis. Scholars, however, have paid little attention to the actual political and institutional logics that shaped this new organization. This article explores the dynamics underpinning the making of EFSA. We examine the way in which learning and power shaped its organizational architecture. It is demonstrated that the lessons drawn from the past and other models converged on the need to delegate authority to an external agency, but diverged on its mandate, concretely whether or not EFSA should assume risk management responsibilities. In this situation of competitive learning, power and procedural politics conditioned the mandate granted to EFSA. The European Commission, the European Parliament and the European Council shared a common interest in preventing the delegation of regulatory powers to an independent EU agency in food safety policy.

  3. Contesting authority: China and the new landscape of power sector governance in the developing world

    Science.gov (United States)

    Hannam, Phillip Matthew

    Two co-constructed trends threaten to complicate global efforts to manage climate change. Electric power in developing countries is becoming more coal-intensive, while the international institutions capable of assisting lower-carbon growth paths are having their authority challenged by an emergent set of institutions under China's leadership. In the last decade Chinese firms and state banks have become central players in power sector development across the developing world; China has been involved in over sixty percent of Africa's hydropower capacity and is the single largest exporter of coal power plants globally. Statistical and qualitative evidence suggests that China's growing role in these power markets has contributed to re-prioritization of the power sector in U.S. bilateral development assistance, complicated negotiation and implementation of coal power finance rules among OECD export credit agencies, and influenced where the World Bank chooses to build hydropower projects. The thesis establishes a framework for understanding responses to discord in development governance by drawing inductively on these contemporary cases. Competition between established and emerging actors increases with two variables: 1) conflicting ideological, commercial and diplomatic goals (difference in interests); and 2) the degree to which the emerging actor challenges rules and norms upheld by the established actor (contested authority). Competitive policy adjustment - one actor seeking to undermine or diminish the other's pursuit of its objectives - has been historically commonplace when an emerging actor challenged an established actor in the regime for development assistance. China's growing authority in global power sector assistance has prompted competitive policy adjustment among established donors while also enabling recipient countries to leverage donors and better direct their own development pathways. The thesis shows that although contested authority increases

    About 15 PBq from both {sup 134}Cs and {sup 137}Cs were released from the Fukushima Dai-ichi Nuclear Power Plant (NPP) because of venting operations and hydrogen explosions. The Ministry of Education, Culture, Sports, Science and Technology of Japan reported total surface deposition of {sup 134}Cs and {sup 137}Cs in Japan. To estimate short-term and long-term impacts of the radiation dose in Japan, it is important to understand the dynamics of radionuclides, especially those of {sup 134}Cs and {sup 137}Cs, on river watershed environments. This study investigated {sup 134}Cs and {sup 137}Cs radioactivity in river systems in Fukushima, Miyagi, Ibaraki and Gunma prefectures, Japan. The secondary radioactive dispersion of radiocesium from the contaminated watershed to the river waters is reported for research areas with widely various radiocesium deposition on ground surfaces at 18 months after the accident. Field experiments were conducted at a fixed station in four rivers (the Uta, Niida, Natsui, and Same Rivers) in Fukushima Prefecture, and the Kuji River, and Naka River in Ibaraki Prefecture in August 2012. The Abukuma River was set up one site at the upper, two sites in the middle reach in Fukushima Prefecture and at one site in the lower area in Miyagi Prefecture. The Tone River system has three stations at the upper river area in Gunma Prefecture and one site at the lower reach in Ibaraki Prefecture. Surface deposition results reveals significant external radioactivity in a zone extending northwest from the NPP. However, a mountainous area in Gunma Prefecture, located about 220 km from Fukushima Dai-ichi NPP south of Fukushima Prefecture, shows similar accumulation of {sup 134}Cs and {sup 137}Cs. The 20 L of surface river waters were collected at the station using buckets. The radioactivity of {sup 134}Cs and {sup 137}Cs in the river waters was measured with gamma-ray spectrometry using ammonium molybdophosphate (AMP)/Cs compound method with a low background Ge

    Beaugelin-Seiller, K.; Brottet, D.

    1994-01-01

    The detection of radionuclides in water, downstream of nuclear installations located on river banks, is often very difficult notably because of their low concentrations. Thus the use of biological indicators is an interesting process to detect radioactive contamination of an aquatic ecosystem. From 1986 to 1990, artificial radionuclides were measured in freshwater mosses sampled downstream of the nuclear power station of Bugey. These field data on the whole, have shown a comparatively good qualitative and quantitative relationship between radioactive composition of liquid waste and radionuclides detected in mosses. In other respects, the results showed up a relatively clear hierarchical structure in the affinity of the different radionuclides for the mosses. To specify these relations, mesh bags containing allochtonous mosses were immersed at four stations downstream of the power plant and regularly sampled during a 10-h waste discharge period. (author)

    The type of monitoring of nuclear power plants in Ukraine practiced in the early nineties provided the supervisory authority with only inadequate access to information about the current safety status of plants. For the Zaporozhye nuclear power plant, unit 5, a technical system to improve operational monitoring has been designed, installed and commissioned for trial operation at the end of 1995 as a pilot project. The system complements existing operational checking and monitoring facilities by including modern means of information technology. It enables concentration on a continuous monitoring of the state of unit 5 in normal operation and in cases of anormalies or incidents so that when recognisable deviations from the regular plant operation occur, the authority can immediately inquire and if necessary impose conditions on the operator. In 1997, the Information and Crisis Centre of the Ukraninian supervisory authority in Kiev was equipped with the most essential technical means necessary for quasi-simultaneous transfer of data and voice and for monitoring purposes and connected to the Centre to the Zaporozhye system. A similar monitoring system for both VVER-440 units of the Rovno nuclear power plant by analogy with the pilot project was specified and put into operation and connected to the ICC in 1998. (orig.)

    The object of this study is to establish the correlates of the phenomenology of conflict and power management in the Jamaican population. A total of 1506 adult individuals were sampled from 2150 households using a stratified sampling method and assessed using the 12 questions of the Jamaica Personality Disorder Inventory (JPDI) on the phenomenology of conflict and power management that are grouped into the psychological features of aggressive social behaviour, unlawful behaviour, socially unacceptable behaviour and financial transgressive behaviour. The database of responses to the demographic and JPDI questionnaires was created and analysed using the Statistical Package for the Social Sciences (SPSS) version 17. Of the national population sampled, 69.1% denied having any phenomenological symptoms of abnormal power management relations while 30.9% of the population admitted to having some degree of conflict and power management, ranging from mild (10.3%), to moderate (17.1), or severe (3.5%). There were 46.55% of the population which had problems with aggressive social behaviour, 9.33% had problems with unlawful behaviour, 9.58% had problems with unacceptable social behaviour and 37.74% had problems with financial transgressive behaviour. Significant gender and socio-economic class patterns for conflict and power management were revealed. This pattern of conflict and power management behaviour is critical in understanding the distinction between normal and abnormal expression of these emotions and actions. Nearly one-third of the sample population ` studied reported problems with conflict, abnormal power and authority management, impulse control and serious aggressive and transgressive behaviour.

    This Environmental Assessment (EA) has been prepared by the US Department of Energy (DOE) to assess the potential environmental impacts associated with the construction and operation of a landfill and technology center for regionally-generated municipal solid waste at the Savannah River Site (SRS) near Aiken, South Carolina. The facility would serve the municipal solid waste disposal needs for SRS and at least nine of the surrounding counties who currently comprise the Three Rivers Solid Waste Authority (TRSWA). Additional counties could become included in the proposed action at some future date. Current Federal and state requirements do not afford individual counties and municipalities within the region encompassing SRS the ability to efficiently or economically operate modern waste management facilities. In addition, consolidation of regional municipal solid waste at one location would have the benefit of reducing the duplicity of environmental consequences associated with the construction and operation of county-level facilities. The option to seek a combined disposal and technology development facility based on a regionally-cooperative effort was selected as a viable alternative to the existing individual SRS or county disposal activities. This document was prepared in compliance with the National Environmental Policy Act (NEPA) of 1969, as amended, the requirements of the Council on Environmental Quality Regulations for Implementing NEPA (40 CFR Part 1021). NEPA requires the assessment of environmental consequences of Federal actions that may affect the quality of the human environment. Based on the potential for impacts described for impacts described herein, DOE will either publish a Finding of No Significant Impact or prepare an environmental impact statement (EIS)

    Studies were conducted on selected Hudson River macrozooplankton species to determine temporal and spatial distributions and responses to power plant operation. Distinguishing morphological and habitat characteristics were determined for the three gammarid amphipods (Gammarus daiberi, G. tigrinus, and G. fasciatus) occurring in the Hudson River. The oedicerotid amphipod Monoculodes edwardsi and the mysid Neomysis americana, in addition to the gammarid amphipods, displayed characteristic diel and seasonal abundances which affect their potential availability for power plant entrainment. The selected macrozooplankton species were utilized in temperature and chlorine bioassays in order to predict responses to cooling water entrainment. Although amphipods (Gammarus spp. and M. edwardsi) survived typical Indian Point cooling water temperatures, N. americana had high mortalities during a 30-minute, 8.3 0 C ΔT at 25 0 C ambient temperature. The bioassay results were substantiated by generally high survivals of entrained amphipods at the Indian Point plant. Neomysis americana were more heat sensitive, as indicated in bioassays, with average entrainment mortalities ranging from 30 to 60 percent during the summer. All species examined had higher immediate and latent mortalities during plant condenser chlorination. The ability of Gammarus to survive condenser passage and exposure to the Indian Point thermal discharge plume indicates that power plant operation on the lower Hudson River Estuary has no adverse impact on local gammarid amphipod populations. Entrained N. americana experience considerable mortalities; however, the impact on Atlantic Coast populations is minimized by the limited exposure of the population fringe to the Indian Point power plant

    Federal financing of an undivided ownership interest of River Bend Nuclear Power Station Unit 1 on a 3293-acre site near St. Francisville, Louisiana is proposed in a supplement to the final environmental impact statement of September 1974. The facility would consist of a boiling-water reactor that would produce a maximum of 2894 megawatts (MW) of electrical power. A design level of 3015 MW of electric power could be realized at some time in the future. Exhaust steam would be cooled by mechanical cooling towers using makeup water obtained from and discharged to the Mississippi River. Power generated by the unit would be transmitted via three lines totaling 140 circuit miles traversing portions of the parishes of West Feliciana, East Feliciana, East Baton Rouge, West Baton Rouge, Pointe Coupee, and Iberville. The unit would help the applicant meet the power needs of rural electric consumers in the region, and the applicant would contribute significanlty to area tax base and employment rolls during the life of the unit. Construction related activities would disturb 700 forested acres on the site and 1156 acres along the transmission routes. Of the 60 cubic feet per second (cfs) taken from the river, 48 cfs would evaporate during the cooling process and 12 cfs would return to the river with dissolved solids concentrations increased by 500%. The terrace aquifer would be dewatered for 16 months in order to lower the water table at the building site, and Grants Bayou would be transformed from a lentic to a lotic habitat during this period. Fogging and icing due to evaporation and drift from the cooling towers would increase slightly. During the construction period, farming, hunting, and fishing on the site would be suspended, and the social infractructure would be stressed due to the influx of a maximum of 2200 workers

    The potential environmental impacts of large-scale storage hydroelectric power (HEP) schemes have been well-documented in the literature. In Europe, awareness of these potential impacts and limited opportunities for politically-acceptable medium- to large-scale schemes, have caused attention to focus on smaller-scale HEP schemes, particularly run-of-river (ROR) schemes, to contribute to meeting renewable energy targets. Run-of-river HEP schemes are often presumed to be less environmentally damaging than large-scale storage HEP schemes. However, there is currently a lack of peer-reviewed studies on their physical and ecological impact. The aim of this article was to investigate the effects of ROR HEP schemes on communities of fish in temperate streams and rivers, using a Before-After, Control-Impact (BACI) study design. The study makes use of routine environmental surveillance data collected as part of long-term national and international monitoring programmes at 23 systematically-selected ROR HEP schemes and 23 systematically-selected paired control sites. Six area-normalised metrics of fish community composition were analysed using a linear mixed effects model (number of species, number of fish, number of Atlantic salmon-Salmo salar, number of >1 year old Atlantic salmon, number of brown trout-Salmo trutta, and number of >1 year old brown trout). The analyses showed that there was a statistically significant effect (pcomposition. The implications of these findings are discussed in this article and recommendations are made for best-practice study design for future fish community impact studies.

    1974-12-01

    Physical, chemical, biological, ecological, and aesthetic aspects of the Wairakei Power Plant are examined, in varying detail, but with primary emphasis on the chemical and thermal effluents. When flows are average or higher in the Waikato River, the Plant's environmental effects are not overly severe. However, operating requirements for the Waikato Hydro-electric System are such that the Plant sporadically produces wastes that may affect the human and natural environment adversely. These adverse effects are not presently too serious, but suggestions are made for improving the Plant's overall environmental performance. Although the point is not discussed in detail, it is clear from the results of the study that any additional thermal plants on the Waikato could strain the river's absorptive capacities severely, unless alternative disposal techniques are used for the various effluents.

    Run-of-river (ROR) hydroelectric power (HEP) schemes are often presumed to be less ecologically damaging than large-scale storage HEP schemes. However, there is currently limited scientific evidence on their ecological impact. The aim of this article is to investigate the effects of ROR HEP schemes on communities of invertebrates in temperate streams and rivers, using a multi-site Before-After, Control-Impact (BACI) study design. The study makes use of routine environmental surveillance data collected as part of long-term national and international monitoring programmes at 22 systematically-selected ROR HEP schemes and 22 systematically-selected paired control sites. Five widely-used family-level invertebrate metrics (richness, evenness, LIFE, E-PSI, WHPT) were analysed using a linear mixed effects model. The analyses showed that there was a statistically significant effect (p<0.05) of ROR HEP construction and operation on the evenness of the invertebrate community. However, no statistically significant effects were detected on the four other metrics of community composition. The implications of these findings are discussed in this article and recommendations are made for best-practice study design for future invertebrate community impact studies.

    Following the classic economic model of tax evasion, taxpayers base their tax decisions on economic determinants, like fine rate and audit probability. Empirical findings on the relationship between economic key determinants and tax evasion are inconsistent and suggest that taxpayers may rather rely on their beliefs about tax authority's power. Descriptions of the tax authority's power may affect taxpayers' beliefs and as such tax evasion. Experiment 1 investigates the impact of fines and beliefs regarding tax authority's power on tax evasion. Experiments 2-4 are conducted to examine the effect of varying descriptions about a tax authority's power on participants' beliefs and respective tax evasion. It is investigated whether tax evasion is influenced by the description of an authority wielding coercive power (Experiment 2), legitimate power (Experiment 3), and coercive and legitimate power combined (Experiment 4). Further, it is examined whether a contrast of the description of power (low to high power; high to low power) impacts tax evasion (Experiments 2-4). Results show that the amount of fine does not impact tax payments, whereas participants' beliefs regarding tax authority's power significantly shape compliance decisions. Descriptions of high coercive power as well as high legitimate power affect beliefs about tax authority's power and positively impact tax honesty. This effect still holds if both qualities of power are applied simultaneously. The contrast of descriptions has little impact on tax evasion. The current study indicates that descriptions of the tax authority, e.g., in information brochures and media reports, have more influence on beliefs and tax payments than information on fine rates. Methodically, these considerations become particularly important when descriptions or vignettes are used besides objective information.

    The paper deals with the legal and organizational aspects as well as with the principles and procedures of the quality assurance (QA) system for particular equipment of nuclear power plants in Czechoslovakia, and the role of governmental authorities in surveillance activities. The basic governmental document is the Decree No.5 (1979) of the Czechoslovak Atomic Energy Commission (CzAEC) on the QA of particular equipment in nuclear power plants with regard to nuclear safety. It is divided into ten sections: opening provisions; classification of the particular equipment; QA programmes; procedures of final elaboration of QA programme documentation; QA principles; QA during design; QA during manufacture, procurement, installation and commissioning; in-service inspection; QA during repair and modifications; and concluding provisions. Governmental surveillance is based on Governmental Resolution No.195 (1977). According to this resolution, inspection must be carried out by an organization which is independent of the manufacturing and operating organizations. This inspection is performed by the Czechoslovak Atomic Energy Commission (for nuclear safety) and by the Czech Safety Work Office and the Slovak Safety Work Office (for technical safety), together with subordinated regional divisions. The activities of these authorities are discussed. (author)

  13. Run-of-river power plants in Alpine regions: whither optimal capacity?

    Science.gov (United States)

    Lazzaro, Gianluca; Botter, Gianluca

    2015-04-01

    Hydropower is the major renewable electricity generation technology worldwide. The future expansion of this technology mostly relies on the development of small run-of-river projects, in which a fraction of the running flows is diverted from the river to a turbine for energy production. Even though small hydro inflicts a smaller impact on aquatic ecosystems and local communities compared to large dams, it cannot prevent stresses on plant, animal, and human well-being. This is especially true in mountain regions where the plant outflow is located several kilometers downstream of the intake, thereby inducing the depletion of river reaches of considerable length. Moreover, the negative cumulative effects of run-of-river systems operating along the same river threaten the ability of stream networks to supply ecological corridors for plants, invertebrates or fishes, and support biodiversity. Research in this area is severely lacking. Therefore, the prediction of the long-term impacts associated to the expansion of run-of-river projects induced by global-scale incentive policies remains highly uncertain. This contribution aims at providing objective tools to address the preliminary choice of the capacity of a run-of-river hydropower plant when the economic value of the plant and the alteration of the flow regime are simultaneously accounted for. This is done using the concepts of Pareto-optimality and Pareto-dominance, which are powerful tools suited to face multi-objective optimization in presence of conflicting goals, such as the maximization of the profitability and the minimization of the hydrologic disturbance induced by the plant in the river reach between the intake and the outflow. The application to a set of case studies belonging to the Piave River basin (Italy) suggests that optimal solutions are strongly dependent the natural flow regime at the plant intake. While in some cases (namely, reduced streamflow variability) the optimal trade-off between economic

    A detailed study on water quality was conducted on rivers Tikara and Brahmani one of which (Brahmani) is the source of water for super thermal power plant in Talcher, Orissa. Four sites were selected for study, 2 in Tikara and the rest in Brahmani. Person's correlation coefficient was worked for all the water quality parameters. High correlations were observed between conductivity with TDS, calcium and chlorides. High correlations were also observed between hardness with chlorides and calcium, and it has been concluded that the result will help in the calculation of some of the parameters without experimental determination. The analyses, show that there is no appreciable pollution in these rivers. However, flyash and pollutants from thermal plant might pollute these rivers. Suggestions have been given to abate pollution. (author)

  15. River longitudinal profiles and bedrock incision models: Stream power and the influence of sediment supply

    Science.gov (United States)

    Sklar, Leonard; Dietrich, William E.

    The simplicity and apparent mechanistic basis of the stream power river incision law have led to its wide use in empirical and theoretical studies. Here we identify constraints on its calibration and application, and present a mechanistic theory for the effects of sediment supply on incision rates which spotlights additional limitations on the applicability of the stream power law. On channels steeper than about 20%, incision is probably dominated by episodic debris flows, and on sufficiently gentle slopes, sediment may bury the bedrock and prevent erosion. These two limits bound the application of the stream power law and strongly constrain the possible combination of parameters in the law. In order to avoid infinite slopes at the drainage divide in numerical models of river profiles using the stream power law it is commonly assumed that the first grid cell is unchanneled. We show, however, that the size of the grid may strongly influence the calculated equilibrium relief. Analysis of slope-drainage area relationships for a river network in a Northern California watershed using digital elevation data and review of data previously reported by Hack reveal that non-equilibrium profiles may produce well defined slope-area relationships (as expected in equilibrium channels), but large differences between tributaries may point to disequilibrium conditions. To explore the role of variations in sediment supply and transport capacity in bedrock incision we introduce a mechanistic model for abrasion of bedrock by saltating bedload. The model predicts that incision rates reach a maximum at intermediate levels of sediment supply and transport capacity. Incision rates decline away from the maximum with either decreasing supply (due to a shortage of tools) or increasing supply (due to gradual bed alluviation), and with either decreasing transport capacity (due to less energetic particle movement) or increasing transport capacity (due less frequent particle impacts per unit bed

    Full Text Available Hydropolitical complexes are emerging to negotiate water-sharing policies that promote politicalstability, regional security, economic prosperity, and environmental sustainability. Yet interstatedisputes are occurring within most hydropolitical complexes, and weak riparians are oftencoerced to agree to water-sharing policies that adversely affect them. This research examines thestrategies weak riparians use to assert leverage in international river basins with asymmetricalpower, and the success of those strategies in achieving cooperation versus conflict. Grounded inthe theoretical framework of hydro hegemony, hard power, and soft power, this study uses crossnational analysis to test the effects of geographic, military, political, economic, technological,and external influence on water governance in eight international river systems. The resultsdemonstrate that weak riparians mobilize the assets and capacities of external actors, such asdonor countries and the World Bank, to increase their leverage within hydropolitical complexes.The study finds that strategies to balance hard power are largely ineffective; they fail to achievecooperative water-sharing arrangements and often exacerbate conflict. In contrast, strategies tobalance economic power and soft power, such as market access and political legitimacy, aremore successful in promoting cooperation and preventing conflict in hydropolitical complexes.

    2015-12-01

    Full Text Available The stature of the National Prosecuting Authority (NPA has been subverted through highly publicised political interference by the executive. Beginning with the marathon legal entanglements of the current South African president the decisions of sitting National Directors of Public Prosecutions (NDPP on high-profile criminal matters, particularly those involving prominent members of the political leadership, have been marred with controversy. Undoubtedly unwarranted intrusion into the prosecutorial domain, at the behest of key political protagonists, has blighted the repute of the NPA. The judiciary too has played a pivotal, if lesser role, in eroding the sagging reputation of the NPA. This article charts the narrative of judicial influence on the diminishing credibility of the NPA, using selected cases from the recent past. It shows that key political events such as the Zuma corruption saga have placed the judiciary together with political forces at centre stage where the focus is their culpability for exceeding their lawful mandate. Finding itself vulnerable as a result of its being the target of rhetoric casting doubt on its integrity and threatening its independence, the judiciary (through a crucial judgment entered the political fray and positioned itself behind what it judged to be the pervasive political sentiment of the day. The article examines whether, subsequently, in an effort to curb undue political influence of the executive on the NPA, the Constitutional Court in Democratic Alliance v President of South Africa interpreted and extended judicial authority in a manner that violated the doctrine of separation of powers. Furthermore, the article argues that in Freedom Under Law v National Director of Public Prosecutions the court again misconstrued its powers by unduly interfering with the discretionary decision-making powers of the NDPP. These cases illustrate that, once they have been issued, the far reaching consequences of judicial

    Niagara Falls and the Niagara River have always attracted great public interest due to their natural beauty, their enormous potential for electricity generation, their recreational value and as an important ecosystem. There have been simultaneous efforts to preserve this unique natural wonder and harness its power through hydroelectric development projects by both the United States and Canada. This paper explores the evolution of these efforts that culminated with the signing of the 1950 Niagara River Water Diversion Treaty that established minimum water flow rates to protect the “scenic beauty” of the falls, allowing the remaining water to be diverted for power production. We examine the rationale that led to specific water flow restrictions and question to what extent they are relevant today, as water intake capacity on the Canadian side has just been extended by around 25%. We find that current restrictions under the Niagara River Water Treaty (that expired in 2000) are not based on sound scientific evidence and estimate the upper limit of potential foregone benefits from clean electricity generation and greenhouse gas reductions. We identify a number of important issues that emerged in the last decades and that would justify an exploration of new treaty rules. - Highlights: • We examine the history of water diversion at Niagara Falls. • We examine the rationale that led to water flow restrictions over Niagara Falls and its relevance today. • We estimate the opportunity cost of foregone energy generation with the new Canadian intake capacity. • Water flow stipulations were not based on the sound scientific or ecosystem analysis. • A renegotiation of the 1950 Niagara River Water Diversion Treaty is overdue

  19. Meeting Ontario's electricity needs : a critical review of the Ontario Power Authority's supply mix advice report

    Gibbons, J.; Fracassi, J.

    2006-01-01

    In December, 2005 the Ontario Power Authority (OPA) outlined its proposed blueprint for meeting Ontario's electricity needs to 2025 in the document entitled Supply Mix Advice Report. As a result of the actions taken by the current government, the OPA believes that Ontario will have adequate electricity supplies to meet the province's needs until 2013. However, it stated that Ontario will require an additional 15,000 megawatts of new generation capacity between 2013 and 2025. The OPA also recommends that a significant proportion of this new generation capacity be nuclear. The Ontario Clean Air Alliance undertook a review of the OPA report and identified several discrepancies including an over-estimation of Ontario's rate of electricity load growth from 2005 to 2025; an under-estimation of the potential for electricity productivity improvements to reduce electricity demand and raise living standards; an under-estimation of renewable energy supply potential; an under-estimation of the potential for biomass and natural gas fired combined heat and power plants to meet electricity needs and increase the competitiveness of Ontario's industries; an under-estimation of the economic costs and risks of nuclear power; and a biased recommendation for a 70 million dollar resource acquisition budget against energy efficiency investments that would reduce demand and raise living standards. This report provides the Ontario Clean Air Alliances' analysis of the OPA report and presents it own recommendations for how Ontario can increase its electricity productivity and meet its electricity supply needs until 2025. The report concluded that the Government of Ontario should direct the OPA to develop a long-term strategy to raise the price of electricity up to its full cost without raising the electricity bills of low income consumers or impairing the competitiveness of Ontario's industries. It was suggested that Ontario's electricity productivity should be increased to the same level as

  20. Hindrances to upstream migration of atlantic salmon (Salmo salar) in a northern Swedish river caused by a hydroelectric power-station

    2001-01-01

    Many Baltic salmon rivers have lost their natural juvenile production due to human activities blocking or reducing access to their spawning grounds, e.g. damming, power generation, partial hinders, etc.. One such hindrance is a hydroelectric complex located in the lower reaches of River Umeaelven in northern Sweden. Water from the forbay created by the dam Norrfors is directed to the Stornorrfors power-station. At times, 100 per cent of the river is directed to the power-station. Water from the power-station then flows via a tunnel and outlet channel to the river. From the point of the tunnel's discharge into the river, the old river bed acts as a bypass channel directing migrating adult fish to a fish ladder located at the base of the dam. In this study, the effect that an additional turbine, that was installed at the power-station in 1986, had on fish passage run-time was examined. Changes in run-time were compared for two periods 1974-1985 and 1986-1995. In 1997, 55 wild and 25 hatchery salmon were captured in the Umeaelven estuary, radio tagged with uniquely coded tags, and tracked upstream. Both manual and automatic loggers were used to locate fish daily. The main findings show that only 26 per cent of the wild salmon and none of the hatchery salmon found the fish ladder. It is suggested that the salmon followed the main water discharge from the power-station outlet and are thus directed away from the entrance to the bypass channel leading to the fish ladder. Salmon respond by moving upstream or downstream depending on the current flow regimes. The bypass channel consists of partial hinders that may explain why it takes on average 52 days for the salmon to migrate 32 km from the estuary to the fish ladder. Adding a fourth turbine at the power-station did not appear to have changed the timing of the migration or the seasonal distribution of the migrating wild salmon through the fish ladder. There was no significant effect of the fourth turbine on the duration

    Radioactive products discharge into natural water streams results in the necessity to regulate nuclear power plant discharges to ensure radiation safety (RS) for population using a river and surrounding river territory. To ensure RS it is necessary to set scientific-founded standards of permissible discharge level of liquid radioactive wastes (LRW) from nuclear power plant assuring observance of hygienic requirements for surface water puring. Volume of permissible LRW discharge into river systems must be set both with provision for concrete physical-geographycal conditions, specficity of utilizing the river and river valley and social-economical peculiarities of crtical population groups. The value of permissible LRW discharge into river systems is determined by three criterion groups: radiological, ecological and hydrological ones. By means of radiological group the internal and external irradiation doses for the whole body and its separate organs are set and RS of population is determined. Ecological criteria include a number of parameters (coefficients of accumulation, distribution and transition) determining quantitative ratios between radioactive element contents in water and separate links of biological chains: soil/water, fish/water, vegetables/water and others. Hydrological criteria determine the degree of waste dilution in rivers, control radioactive contamination of flood-lands areas and in common with ecological criteria determine radionuclide contents in soil and food products. A method of determining average annual values of LRW dilution in river waters is presented [ru

    Full Text Available Identification and assessment of strategies for the conservation and multifunctional development of green open space in the urban fringe of European urban regions is a challenge to both the academic and the real life world. Within the EU funded research project PLUREL – Peri-urban land use relationships – ‘Strategies and sustainability assessment tools for urban rural linkages’, we developed a methodology for international comparison of regional strategies that considers the policy context at supra-regional level. This methodology helped to explain the reported impacts of strategies. For this we further elaborated the theoretical concept of policy arrangements and policy dimensions by Van Tatenhove et al. (2000 and Arts et al. (2006. Strategies and policy contexts referred to are from Montpellier Agglomeration, a formal coalition of now 31 municipalities, Leipzig-Halle region, a functional urban region (FUR with governance coalitions around green open space preservation strategies, and Hangzhou in China, a very large city with hierarchical formal government. Results showed how the means of influence from different government levels can complement and reinforce each other and raise the effectiveness of the strategies. A combination of hierarchical government with a horizontal coalition between local authorities covering the full FUR can be very effective for managing the land use developments in the urban fringe, even when private business, CSOs or other NGOs are not included in the coalition. Supra-regional authorities do not have to possess the land resources, but setting the Rules of the Game is a powerful means of influence to coerce local municipalities to preserve green open space in the urban fringe.

  5. Study of the long-range effects of radioactive effluents from nuclear power plants in the Rhine river using 58Co and 60Co as tracers

    International Nuclear Information System (INIS)

    Mundschenk, H.

    1992-01-01

    58 Co and 60 Co were used to trace the long-range effects of nuclear power plants in the aquatic environment of the Rhine river basin. 60 Co, preferentially originating from Swiss installations, could be detected in suspended matter along the river over several hundreds of kilometres, even to the Lower Rhine. This nuclide was transferred to the bottom layer by sedimentation along the whole stretch, especially in high-sedimentation zones, which must be considered to be the so-called 'critical impact areas' for estimation of the radiological effects of the nuclear power plants in the aquatic environment. 58 Co, mainly discharged by French and Swiss installations, could be measured in suspended matter. In sediment samples, however, this nuclide could not, or only occasionally, be detected because transfer to the sediment layer proceeded at a rather low rate relative to the decay rate of 58 Co. From these findings, it follows that impact control of these nuclear power plants should not be restricted to their immediate aquatic environments but should be extended to the whole river. Estimation of the resulting radiation exposure, based on the measured concentrations of 60 Co and 58 Co in sediment assuming standard conditions, showed that the dose rates generated by the most sensitive pathway, and indeed by other nuclides and different pathways, were far below the dose limit defined in German legal regulations and therefore were negligible.

  7. Does the Sole Description of a Tax Authority Affect Tax Evasion? - The Impact of Described Coercive and Legitimate Power

    Science.gov (United States)

    Hartl, Barbara; Hofmann, Eva; Gangl, Katharina; Hartner-Tiefenthaler, Martina; Kirchler, Erich

    2015-01-01

    Following the classic economic model of tax evasion, taxpayers base their tax decisions on economic determinants, like fine rate and audit probability. Empirical findings on the relationship between economic key determinants and tax evasion are inconsistent and suggest that taxpayers may rather rely on their beliefs about tax authority’s power. Descriptions of the tax authority’s power may affect taxpayers’ beliefs and as such tax evasion. Experiment 1 investigates the impact of fines and beliefs regarding tax authority’s power on tax evasion. Experiments 2-4 are conducted to examine the effect of varying descriptions about a tax authority’s power on participants’ beliefs and respective tax evasion. It is investigated whether tax evasion is influenced by the description of an authority wielding coercive power (Experiment 2), legitimate power (Experiment 3), and coercive and legitimate power combined (Experiment 4). Further, it is examined whether a contrast of the description of power (low to high power; high to low power) impacts tax evasion (Experiments 2-4). Results show that the amount of fine does not impact tax payments, whereas participants’ beliefs regarding tax authority’s power significantly shape compliance decisions. Descriptions of high coercive power as well as high legitimate power affect beliefs about tax authority’s power and positively impact tax honesty. This effect still holds if both qualities of power are applied simultaneously. The contrast of descriptions has little impact on tax evasion. The current study indicates that descriptions of the tax authority, e.g., in information brochures and media reports, have more influence on beliefs and tax payments than information on fine rates. Methodically, these considerations become particularly important when descriptions or vignettes are used besides objective information. PMID:25923770

  9. Tracing cohesive sediment transportation at river mouths around Tokyo, Japan by Cesium originated from Fukushima Daiichi Power Plant

    koibuchi, Y.

    2012-12-01

    Sediment transport at river mouths, which consists of suspended-load and bed-load, has not been fully understood, since bed-load transport of cohesive sand is difficult to observe. Especially, the impact of sediment transport on the total amount of fine-grained cohesive sediment has not been elucidated. Cesium-134 and cesium-137 were spread from the Fukushima Daiichi Nuclear Power Plant (FDNPP) after the earthquake of March 11 of 2011, and attached to the fine-grained sand on the land. The contaminated sand flowed into the river mouths through the rivers possibly due to the complex physical processes in estuarine areas. To evaluate the fine-grained sediment transport around Tokyo and Tokyo Bay, field observations were carried out utilizing radionuclide originated from FDNPP as an effective tracer. The cohesive sediment transport at three different river mouths around Tokyo was successfully quantified. The cohesive sediment transport deposited in the estuary was found to be greatly dependent on the land use, geometry, river discharge and salinity. In addition,the transport driven by the rainfall was minute, and its behavior was quite different from suspended solids. Although further field observations of radionuclide are necessary, it is clear that fine-grained sediment in the bay from rivers already settled on the river mouth by aggregation. The settled sand will not move even in rainfall events. Consequently, the transport of radionuclide to the Pacific Ocean may not occur.; Cesium distribution around Tokyo Bay ; Cesium Concentration in Edogawa river

  10. B, As, and F contamination of river water due to wastewater discharge of the Yangbajing geothermal power plant, Tibet, China

    Science.gov (United States)

    Guo, Qinghai; Wang, Yanxin; Liu, Wei

    2008-11-01

    Thermal waters from the Yangbajing geothermal field, Tibet, contain high concentrations of B, As, and F, up to 119, 5.7 and 19.6 mg/L, respectively. In this paper, the distribution of B, As, and F in the aquatic environment at Yangbajing was surveyed. The results show that most river water samples collected downstream of the Zangbo River have comparatively higher concentrations of B, As, and F (up to 3.82, 0.27 and 1.85 mg/L, respectively), indicating that the wastewater discharge of the geothermal power plant at Yangbajing has resulted in B, As, and F contamination in the river. Although the concentrations of B, As, and F of the Zangbo river waters decline downstream of the wastewater discharge site due to dilution effect and sorption onto bottom sediments, the sample from the conjunction of the Zangbo River and the Yangbajing River has higher contents of B, As, and F as compared with their predicted values obtained using our regression analysis models. The differences between actual and calculated contents of B, As, and F can be attributed to the contribution from upstream of the Yangbajing River. Water quality deterioration of the river has induced health problems among dwellers living in and downstream of Yangbajing. Effective measures, such as decontamination of wastewater and reinjection into the geothermal field, should be taken to protect the environment at Yangbajing.

    Full Text Available Problem Setting. The article studies the issue of demarcation of powers of local administrations and other public authorities, local governments in the sphere of land relations. Emphasized the special legal status of local state administrations is to combine the powers of the authority of general and special jurisdiction. Paper objective. Local administration is a local executive body and is part of the executive power. The local administration within their authority exercises executive power in the territory of the administrative-territorial unit, as well as implementing powers delegated to it by the respective council. Paper main body. Powers of special competence in particular, carry out structural subdivisions of local state administrations, the jurisdiction of which include question of sectoral or functional management in the relevant territory (eg, health administration, financial management, etc.. Conclusions. Analyzing the above legal provisions, the authority of the local administration can be understood as assigned to it by the State and enshrined in law the obligation to exposure to certain social relations. In other words, the powers of local state administrations are certain activities of the state in the face of local state administration. This is consistent with the understanding of the general theory of law the concept of «state functions» - the basic perspectives that express its nature and social purpose in the management of public affairs.

    Full Text Available Need of electrical energy is increasing along with people population and economic growth. According to PLN data, Bali Province’s electrical consumption is predicted growth 5,6% in average every year. Until year 2007, electrical condition in Bali is categorized critical. If Power Plat in Bali, PLTG Gilimanuk that has power 130 MW is out of system, affecting Bali’s electrical back up is minus. Consecuenlly, it will be extinguishing if there is not adding power plan or new energy supply. This problem needs to be anticipated by use of thermal energy program such as coal, gas and geothermal and use of alternative energy such as solar, wind and ocean energies. Regency of Buleleng is one of Regency in Bali having potency of renewable energy development especially water resource. It has some rivers that have potency to be developed as a Micro Hydro Power Plant (PLTMH. One of them is Kelampuak River which is located in Tamblang Village. As a first step in developing of Micro Hydro Power Plant, it needs to be known water debit and head of the river. For that reason, it needs to be investigated debit and head of Kelampuak River so that it can be predicted the power can be generated.

  13. Implications of power plant mortality for management of the Hudson River striped bass fishery

    Goodyear, C.P.

    1988-01-01

    The Atlantic coastal stock of striped bass apparently declined from colonial times to the early 1930s and subsequently recovered. The reasons for the decline and recovery are not known, but fishing remains a possible explanation, which would suggest population sensitivity to increased mortality. Evidence suggests that fishing mortality has been increasing in recent years and will continue to increase in the absence of management intervention. The consequence of increased fishing mortality is an increase in the marginal effect of the power plant mortality which based on the utilities' models and parameter fits, could result in important reductions in the Hudson River striped bass population. Any management actions imposed to arrest population decline or to increase yield per effort in the fishery would be required to mitigate the impact of the power plants by reducing fishing mortality. It is estimated that a 20% conditional power plant mortality is equivalent to a 14% increase in the number of average fishermen using the stock. Consequently, should any management intervention be required on behalf of the population, managers would be required to reduce fishing mortality by about 14% just to account for the power plant mortality. 26 refs., 5 figs., 4 tabs

    The U.S. Department of Energy (DOE) proposes to consent to a proposal by the Puerto Rico Electric Power Authority (PREPA) to allow public access to the Boiling Nuclear Superheat (BONUS) reactor building located near Rincon, Puerto Rico for use as a museum. PREPA, the owner of the BONUS facility, has determined that the historical significance of this facility, as one of only two reactors of this design ever constructed in the world, warrants preservation in a museum, and that this museum would provide economic benefits to the local community through increased tourism. Therefore, PREPA is proposing development of the BONUS facility as a museum

    A sampling program to assess the effects of entrainment in the cooling water systems at the Fort Calhoun and Cooper Nuclear Stations on larval fishes was carried out in the months of May, June, and July of 1974--1976. Fish larvae were collected with 2.3 m long, 0.5 m diameter Nitex plankton nets. The samples were taken to laboratory facilities where the living and dead larvae were separated from the debris, counted, and preserved for later identification and measurement. Samples collected above the intake structures of the power plants were used to determine the seasonal patterns, species composition, and abundance of ichthyoplankton in this region of the Missouri River. Relatively low larval fish densities throughout May and early June were generally followed by a single 2 to 3 week long peak in density in late June and early July, due primarily to the larvae of Aplodinotus grunniens. The observed densities then declined to near zero by the end of July. The horizontal distribution of ichthyoplankton was determined by dividing the river above the intake into three sections and sampling the sites sequentially. The highest concentrations of larvae were generally found along the cutting bank (Nebraska shore) and the lowest in the middle of the river. Twenty-four hour sampling was conducted to identify possible diurnal differences in the ichthyoplankton densities above the intake. On six occasions, collections were made every two hours over a 24-hour period. Although great variations in densities were noted over the sampling period, significant differences between mean day and night densities were demonstrated only once, and no recurring temporal pattern in drift rates was identified. Net-induced sampling mortality was found to be a significant factor in the analysis of entrainment mortality

    2017-04-01

    The people's perception on environmental and socio-economic impacts due to three hydro-electric projects (HEPs; commissioned and under construction) were studied in the north-west Indian Himalaya. Surveys among 140 project-affected people (PAPs) using a checklist of impacts indicate that among the negative impacts, decrease in flora/fauna, agriculture, flow of river, aesthetic beauty; and increase in water pollution, river bed quarrying for sand/stone, human settlement on river banks and social evils; and among the positive impacts, increase in standard of living, road connectivity, means of transport, public amenities, tourism and environmental awareness were related with HEPs. The PAPs tend to forget the negative impacts with the age of the HEPs after it becomes functional, and the positive impacts seem to outweigh the negative impacts. Study concludes that it is difficult to separate the compounding impacts due to HEP construction and other anthropogenic and natural factors, and in the absence of cause-and-effect analyses, it is hard to dispel the prevailing notion that HEPs are undesirable in the study area that led to agitations by the environmentalists and stopped construction of one of these HEPs. To overcome the situation, multi-disciplinary scientific studies involving the PAPs need to be carried out in planning and decision-making to make HEPs environment friendly and sustainable in this region. There is also a need to adopt low carbon electric power technologies and promote a decentralized energy strategy through joint ventures between public and private companies utilizing locally available renewable energy resources.

    1988-01-01

    Between 1963 and 1980, the Hudson River estuary was the focus of one of the most ambitious environmental research and assessment programs ever performed. The studies supported a series of US federal proceedings involving licenses and discharge permits for two controversial electric power generating facilities: the Cornwall pumped storage facility, and units 2 and 3 of the Indian Point nuclear generating station. Both facilities were to draw large volumes of water from a region of the Hudson used as spawning and nursery habitat by several fish species, including the striped bass. Fishermen and conservationists feared that a major fraction of the striped bass eggs and larvae in the Hudson would be entrained with the pumped water and killed. Additional fish would be killed on trash screens at the intakes. Scientists were asked to aid the utility companies and regulatory agencies in determining the biological importance of entrainment and impingement. This monograph contains both technical papers that present research results and synthesis papers that summarize and interpret the results. The intent was to: (1) summarize the scientific issues and approaches; (2) present the significant results of the Hudson River biological studies; (3) describe the role of the studies in the decision-making process; (4) evaluate the successes and failures of the studies; and (5) present recommendations for future estuarine impact assessments.

  19. Thermodynamics, maximum power, and the dynamics of preferential river flow structures at the continental scale

    Directory of Open Access Journals (Sweden)

    A. Kleidon

    2013-01-01

    Full Text Available The organization of drainage basins shows some reproducible phenomena, as exemplified by self-similar fractal river network structures and typical scaling laws, and these have been related to energetic optimization principles, such as minimization of stream power, minimum energy expenditure or maximum "access". Here we describe the organization and dynamics of drainage systems using thermodynamics, focusing on the generation, dissipation and transfer of free energy associated with river flow and sediment transport. We argue that the organization of drainage basins reflects the fundamental tendency of natural systems to deplete driving gradients as fast as possible through the maximization of free energy generation, thereby accelerating the dynamics of the system. This effectively results in the maximization of sediment export to deplete topographic gradients as fast as possible and potentially involves large-scale feedbacks to continental uplift. We illustrate this thermodynamic description with a set of three highly simplified models related to water and sediment flow and describe the mechanisms and feedbacks involved in the evolution and dynamics of the associated structures. We close by discussing how this thermodynamic perspective is consistent with previous approaches and the implications that such a thermodynamic description has for the understanding and prediction of sub-grid scale organization of drainage systems and preferential flow structures in general.

    Survival studies of juvenile salmonids implanted with acoustic tags have been conducted at hydroelectric dams within the Federal Columbia River Power System (FCRPS) in the Columbia and Snake rivers between 2010 and 2014 to assess compliance with dam passage survival standards stipulated in the 2008 Biological Opinion (BiOp). For juvenile salmonids migrating downstream in the spring, dam passage survival defined as survival from the upstream dam face to the tailrace mixing zone must be ≥96% and for summer migrants, ≥93%, and estimated with a standard error ≤1.5% (i.e., 95% confidence interval of ±3%). A total of 29 compliance tests have been conducted at 6 of 8 FCRPS main-stem dams, using over 109,000 acoustic-tagged salmonid smolts. Of these 29 compliance studies, 23 met the survival standards and 26 met the precision requirements. Of the 6 dams evaluated to date, individual survival estimates range from 0.9597 to 0.9868 for yearling Chinook Salmon, 0.9534 to 0.9952 for steelhead, and 0.9076 to 0.9789 for subyearling Chinook Salmon. These investigations suggest the large capital investment over the last 20 years to improve juvenile salmon passage through the FCRPS dams has been beneficial.

    The survival of Hudson River fishes, juveniles and adults, after they had been impinged on continuously rotated traveling screens at the Bowline Point and Danskammer Point power plants was examined. Survival of principal species was similar at the two plants, and estimates of survival improved as monitoring stress was reduced. Adjusted for survival of control fish, survival over 84-108 h after fish were recovered from the screens was highest for Atlantic tomcod, striped bass, and white perch (50-90%) and lowest for bay anchovy, alewife, and blueback herring; other species showed intermediate survival. Survival of striped bass and white perch was positively correlated with water temperature in winter and with conductivity in spring and fall. Continual rotation of the screens, which shortens the average time that fish are impinged, increased survival over that associated with intermittent rotation. 24 refs., 9 figs., 4 tabs

  3. Feasibility determination of low head hydroelectric power development at existing sites: Mousam River Project

    Energy Technology Data Exchange (ETDEWEB)

    1979-06-01

    The technical and economic feasibility of low head hydroelectric power development at existing sites along the Mousam River in southeastern Maine was studied. The following areas were investigated: determination of available energy; development of restoration concepts; environmental studies; historical and archeological studies; assessment of civil construction requirements; geotechnical and geologic assessment of existing dams; assessment of turbine alternatives; assessment of generator and utility interface alternatives; economic analysis; and restoration concept evaluation and selection. The results of the hydropower evaluation showed that: of the seven sites evaluated, only four can be considered economically feasible for refurbishment at this time; the use of used and/or rebuilt equipment is more economically attractive than new equipment; the cost of equipment at each site was of the same order as the cost of the dam reconstruction; and the cost of fuel prices will be the determining feature of whether the sites should be reconstructed.

    In a first bibliographic part, after some generalities on radioactivity and nuclear power, general principles of radiation protection and national and international regulations are presented. The methodology of the radioecological study involved in site selection is developed. In a second more experimental part, the processing of radiocobalt gamma radioactivity measurement in water, fishes, plants and Rhone river sediments demonstrates the influence of age and geographical situation of the nuclear power stations located along the river. A laboratory experiment of cobalt 60 transfer from chironomes larvae to carp is carried out. Comparison with the results of other laboratory experiments makes it possible to propose an experimental model of cobalt transfer within a fresh water ecosystem; radioactivity levels calculated for various compartments seem to be consistent with the Rhone river levels [fr

  8. Experience gained in Hungary on the role and responsibility of the public health authority in the nuclear power programme

    1983-01-01

    The public health service of every country has a basic responsibility for maintaining and continuously improving the standard of health of its population. A significant part of this general responsibility, which has grown in importance in recent years, is radiation protection. While substantial economic, social, medical and scientific benefits are derived from various applications of nuclear energy, health authorities must insist on adequate control to protect the population from excessive exposure to radiation. Safety in the nuclear power industry means the assurance that all operational activities are carried out without undue radiation hazard to the general public and to the persons on-site. It is essential, therefore, that national public health authorities give immediate attention to their responsibilities for radiation protection and ensure the development of an adequate system of control as soon as initiation of a nuclear power programme has been decided. The role and responsibility assigned in Hungary to the public health authority by the government, the development of its organizational structure and of its control system and the actions taken to assert radiation protection requirements in the nuclear power programme of the country from the very beginning of its institution till the commissioning of the first 440 MW(e) unit of the nuclear power plant at Paks are reviewed.

    Laverie, M.; Flandrin, R.

    1991-01-01

    The French experience has led the safety authority to pay particular attention to the competence of a nuclear operator and to the exercise of his responsibility. In this context, safety does not seem to be improved by the imposition of too many regulations and control activities. On the contrary, an excessive regulatory framework may blunt the operator's awareness of his responsibility. It is the duty of the safety authority to fix the safety objectives. It is the operator's duty to establish the practical conditions for attaining these objectives and to justify these conditions to the safety authority. It is also his duty to implement them correctly. The authority must then verify the quality of this implementation by random inspection methods. Each of the two partners, each conforming to his role and exercise of his particular responsibilities, must remain vigilant. These different actions necessitate a permanent technical dialogue which is not in contradiction with the exercise of strict regulatory control. (orig.)

We contrast two EIA cases in hydro-power generation plans made for the Ii River, Finland in different decades, and evaluate how impact assessment in these cases has contributed to the creation, mediation and resolution of conflicts. We focus on the elements of distributional and procedural justice that made the former EIA process more legitimate and consensual and the latter more conflictual. The results indicate that it is crucial for conflict mediation to include all the values and interests of the parties in the goal-setting process and in the definition and assessment of alternatives. The analysis also indicates that procedural justice is the most important to help the people and groups involved to accept the legitimacy of the impact assessment process: how different parties and their values and interests are recognized, and how participation and distribution of power are organized in an impact assessment process. It is confirmed in this article that SIA may act as a mediator or a forum providing a process through which competing knowledge claims, various values and interests can be discussed and linked to the proposed alternatives and interventions.

  12. The gas and electric power markets opening in Europe, the implementation of the regulation authorities

    International Nuclear Information System (INIS)

    2001-12-01

    Because the gas and the electric power are not simple goods, the opening of their market needs a whole reflexion where the governments must be involved. To analyse this opening, this report presents in a first part the traditional organization of the gas and electric power sectors marked by the strong presence of the government and the end of this organization at the end of the years 1980. It details then the new regulation, the operators and the effects of the competition. In a last part it provides propositions for the institutional framework in France. (A.L.B.)

    The Sixth Department of the Nuclear, Industrial and Environmental Regulatory Authority of Russia, Scientific and Engineering Centre for Nuclear and Radiation Safety process, analyse and use the information on nuclear power plants (NPPs) operational experience or NPPs safety improvement. Safety performance indicators (SPIs), derived from processing of information on operational violations and analysis of annual NPP Safety Reports, are used as tools to determination of trends towards changing of characteristics of operational safety, to assess the effectiveness of corrective measures, to monitor and evaluate the current operational safety level of NPPs, to regulate NPP safety. This report includes a list of the basic SPIs, those used by the Russian safety regulatory authority in regulatory activity. Some of them are absent in list of IAEA-TECDOC-1141 ('Operational safety performance indicators for nuclear power plants'). (author)

  14. They bewitched the generator: state power and religious authority at the New Year’s festival in Makunduchi, Zanzibar

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available The New Year’s festival in Makunduchi, Zanzibar, has been one of the central sites for the interaction between state power and religious authority. It has changed considerably since colonial times, as political rituals were grafted onto religious ones, and a commercial fair developed. In this article, it is argued that these changes can be explained in part by the renegotiation, both in conflict and co-operation, of the relationship between local religious experts and state officials. First the New Year’s rituals as central practices for the production of local religious authority is analysed. Then the colonial history of the festival is discussed, before finally turning to the interactions between state power and local authority at the festival in post-colonial times.

    The peculiarities of radionuclide depositing in the silt of the river Arbuzynka in the place of discharge of sewerage water from South Ukrainian Atomic Power Plant have been studied. According to the finding of the observation, the main contribution to the total radioactivity of the sewerage water for the entire period of the plant operation was made by Cs-137. The greatest contamination of the river was observed in 1988 and 1993. It has been established that for the whole period of the plant operation two processes developed dynamically in the Arbuzynka, e.i. Cs-137 accumulation by the bottom deposits and its reserve receipt by the water. The process of accumulation was more dynamic

    The construction of human-controlled watercourses to meet the need for hydroelectric power has substantially changed freshwater ecosystems, as well as the cultural dynamics of local communities along the Kemi River. At the moment there are 21 hydropower plants in the Kemi River basin, and further building is still topical. The construction of hydropower plants gave benefits but it also caused damages to the people living along the Kemi River. It was a deathblow to salmon migration. The alteration of the river has radically changed the water environment, the landscape and the usage of the river environment. The processed conflicts and paid compensations are always connected to economic losses, but the river has also many other aspects and meanings from the viewpoint of a riverman. The planning and building of hydroelectric plants took place at the same time with other significant events in northern Finland. The rise of the forestry industry, the Second World War, post-war reconstruction and structural changes in society framed the electrification of northern rivers. The transformation from an agrarian society to a service and information society happened unusually fast in Finland. It involved every aspect of local people's lives, as the physical environment, local culture, social relations, means of income and the surrounding society changed in a short period of time. In my research I examine the changes caused by the electrification of the Kemi River in their temporal and spatial context. The focus is on the perspectives of local people and their personal relationships with the environment, but on the other hand also on the power relations within various actor groups. From my interview data I have identified four different adaptation strategies: compliant builders, those in denial, resigned bystanders and opposing resisters. These strategies may be found overlapping in the stories of the interviewees. Local residents have had an opportunity to realign

    This report discusses the possible environmental consequences of a planned hydroelectric power development of the river Grunnaai, Norway. The consequences are found to be small, provided the proper counter measures are taken. Without counter measures, there may be moderate consequences on fish populations and botanical conditions, directly dependent on the changed water flow. The greatest value of the area concerned lies in its unspoiled wilderness character. There are extensive lists of birds and mammals and plant species registered in the river valley. 51 refs., 7 figs., 4 tabs

  2. A BIRD’S EYE VIEW ON CITIZENS’ TRUST IN AND POWER OF TAX AUTHORITIES IN EAST AND SOUTH ASIA

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available In tax behavior research, “slippery slope” framework represents an important instrument of assessing compliance, based on its two dimensions: trust in authorities (citizens’ perceptions regarding authorities’ disposition to work for the sake, safety and benefit of people and power of authorities (authorities’ ability to chase, catch and punish evaders. The increase/decrease of trust and power as well as their interlacement engender the type of compliance, i.e., voluntary or enforced, and ultimately the profile of the interaction climate between taxpayers and authorities. In this paper we explain taxpayers’ trust in authorities and their perceptions of authorities’ power with the help of socio-economic, financial, political, psychological proxies in eastern and southern Asian jurisdictions like China, Hong Kong SAR, India, Japan, Republic of Korea and Pakistan. For this purpose, we tackle several aspects, such as political regime, voice and accountability, political stability, citizens’ involvement in public decisions, tax law transparency, degree in which citizens receive information about public expenditures and indicators, such as government effectiveness, rule of law, regulatory quality, control for corruption, weaving them into an attire of analytical insights meant to serve policy makers and inform laypeople.

  3. Calculation of Savannah River K Reactor Mark-22 assembly LOCA/ECS power limits

    International Nuclear Information System (INIS)

    Fischer, S.R.; Farman, R.F.; Birdsell, S.A.

    1992-01-01

    This paper summarizes the results of TRAC-PF1/MOD3 calculations of Mark-22 fuel assembly of loss-of-coolant accident/emergency cooling system (LOCA/ECS) power limits for the Savannah River Site (SRS) K Reactor. This effort was part of a larger effort undertaken by the Los Alamos National Laboratory for the US Department of Energy to perform confirmatory power limits calculations for the SRS K Reactor. A method using a detailed three-dimensional (3D) TRAC model of the Mark-22 fuel assembly was developed to compute LOCA/ECS power limits. Assembly power was limited to ensure that no point on the fuel assembly walls would exceed the local saturation temperature. The detailed TRAC model for the Mark-22 assembly consisted of three concentric 3D vessel components which simulated the two targets, two fuel tubes, and three main flow channels of the fuel assembly. The model included 100% eccentricity between the assembly annuli and a 20% power tilt. Eccentricity in the radial alignment of the assembly annuli arises because axial spacer ribs that run the length of the fuel and targets are used. Wall-shear, interfacial-shear, and wall heat-transfer correlations were developed and implemented in TRAC-PF1/MOD3 specifically for modeling flow and heat transfer in the narrow ribbed annuli encountered in the Mark-22 fuel assembly design. We established the validity of these new constitutive models using separate-effects benchmarks. TRAC system calculations of K Reactor indicated that the limiting ECS-phase accident is a double-ended guillonite break in a process water line at the pump discharge (i.e., a PDLOCA). The fuel assembly with the minimum cooling potential is identified from this system calculation. Detailed assembly calculations then were performed using appropriate boundary conditions obtained from this limiting system LOCA. Coolant flow rates and pressure boundary conditions were obtained from this system calculation and applied to the detailed assembly model

    The Wabash River Integrated Methanol and Power Production from Clean Coal Technologies (IMPPCCT) project is evaluating integrated electrical power generation and methanol production through clean coal technologies. The project is conducted by a multi-industry team lead by Gasification Engineering Corporation (GEC), and supported by Air Products and Chemicals, Inc., Dow Chemical Company, Dow Corning Corporation, Methanex Corporation, and Siemens Westinghouse Power Corporation. Three project phases are planned for execution over a three year period, including: (1) Feasibility study and conceptual design for an integrated demonstration facility, and for fence-line commercial plants operated at Dow Chemical or Dow Corning chemical plant locations; (2) Research, development, and testing to define any technology gaps or critical design and integration issues; and (3) Engineering design and financing plan to install an integrated commercial demonstration facility at the existing Wabash River Energy Limited (WREL) plant in West Terre Haute, Indiana. This report describes management planning, work breakdown structure development, and feasibility study activities by the IMPPCCT consortium in support of the first project phase. Project planning activities have been completed, and a project timeline and task list has been generated. Requirements for an economic model to evaluate the West Terre Haute implementation and for other commercial implementations are being defined. Specifications for methanol product and availability of local feedstocks for potential commercial embodiment plant sites have been defined. The WREL facility is a project selected and co-funded under the fifth phase solicitation of the U.S. Department of Energy's Clean Coal Technology Program. In this project, coal and/or other solid fuel feedstocks are gasified in an oxygen-blown, entrained-flow gasifier with continuous slag removal and a dry particulate removal system. The resulting product synthesis

    his own personal ambition. Burning ambition—his own personal sense of political self-preservation—trumped Johnson's early beliefs about civil rights. Therefore because of his personal ambition he kept his opinions about civil rights silent while his operators utilized "out of sight, out of mind" policies towards race relations when necessary. While building this political community Johnson pledged electricity for votes. He had two goals: (1) create a market for LCRA-generated power to prevent private utilities from acquiring the power, and (2) create a political machine. Initially growth occurred slowly but Johnson used modern forms of communications and propaganda to construct a community; including radio, newsprint, theater, and public events and affairs. Johnson also laid the foundations for this community through the creation of shared community space and the promotion of a shared community-mindset. Johnson prioritized the creation of these community spaces over the construction of transmission lines and engaged in deceit when necessary—Arthur Stehling committed forgery—while pursuing Johnson's plans for the formation of this political machine through the conception of a new, common community. Johnson pushed for optimal growth and utilized every opportunity for publicity. These new structures signified the changes occurring across the landscape and for the first time the people of Central Texas began to feel the relief of the New Deal—five years after President Roosevelt initiated relief efforts. Subsequently, the people of Central Texas supported Johnson in his political endeavors. Secondly, this thesis explores the geographical expansion of multipurpose river development and rural electrification operations in Central Texas. Expansion was priority number one because this increased Johnson's political clout in Central Texas. Johnson expanded his control by infiltrating or manipulating newly forming rural electric cooperatives. His operators side

  13. Snow Cover, Snowmelt Timing and Stream Power in the Wind River Range, Wyoming

    Science.gov (United States)

    Hall, Dorothy K.; Foster, James L.; DiGirolamo, Nicolo E.; Riggs, George A.

    2011-01-01

    Earlier onset of springtime weather, including earlier snowmelt, has been documented in the western United States over at least the last 50 years. Because the majority (is greater than 70%) of the water supply in the western U.S. comes from snowmelt, analysis of the declining spring snowpack (and shrinking glaciers) has important implications for the management of streamflow. The amount of water in a snowpack influences stream discharge which can also influence erosion and sediment transport by changing stream power, or the rate at which a stream can do work, such as move sediment and erode the stream bed. The focus of this work is the Wind River Range (WRR) in west-central Wyoming. Ten years of Moderate-Resolution Imaging Spectroradiometer (MODIS) snow-cover, cloud-gap-filled (CGF) map products and 30 years of discharge and meteorological station data are studied. Streamflow data from streams in WRR drainage basins show lower annual discharge and earlier snowmelt in the decade of the 2000s than in the previous three decades, though no trend of either lower streamflow or earlier snowmelt was observed within the decade of the 2000s. Results show a statistically-significant trend at the 95% confidence level (or higher) of increasing weekly maximum air temperature (for three out of the five meteorological stations studied) in the decade of the 1970s, and also for the 40-year study period as a whole. The extent of snow-cover (percent of basin covered) derived from the lowest elevation zone (2500-3000 m) of the WRR, using MODIS CGF snow-cover maps, is strongly correlated with maximum monthly discharge on 30 April, where Spearman's Rank correlation, rs,=0.89 for the decade of the 2000s. We also investigated stream power for Bull Lake Creek above Bull Lake; and found a trend (significant at the 90% confidence level) toward reduced stream power from 1970 to 2009. Observed changes in streamflow and stream power may be related to increasing weekly maximum air temperature

  14. A preliminary look at the impacts of warming on the federal Columbia River power system

    International Nuclear Information System (INIS)

    Stephan, N.

    2008-01-01

    Studies have indicated that the precipitation changes resulting from climatic warming are unlikely to be distinguishable from natural variability until late in the 21. century. This study presented scenarios and projected changes for the Federal Columbia River power system that used volume and runoff data in monthly time-steps. A streamflow model of data from the previous 44 years was also used. The region is currently meeting 50 per cent of its loads with clean hydro-generation, and is now examining ways of limiting greenhouse gas (GHG) emissions as electricity loads continue to grow. The impacts of climate change were compared with projected loads up to the year 2040. Flow targets for regional fish operations peak between April and July. Volume changes in water as a result of hydroelectricity projects in the region have also been simulated. Monitoring tools and meteorological data were presented as well as watershed run-off data from 1929 to 2008. Policies related to climate change continue to be challenged by both legal and political issues as well as a lack of strategic planning. It was concluded that accurate system modelling is needed to avoid the impacts of costly and un-informed decision-making processes. tabs., figs

    Full Text Available Moving towards energy systems with high variable renewable energy shares requires a good understanding of the impacts of climate change on the energy penetration. To do so, most prior impact studies have considered climate projections available from Global Circulation Models (GCMs. Other studies apply sensitivity analyses on the climate variables that drive the system behavior to inform how much the system changes due to climate change. In the present work, we apply the Decision Scaling approach, a framework merging these two approaches, for analyzing a renewables-only scenario for the electric system of Northern Italy where the main renewable sources are solar and hydropower. Decision Scaling explores the system sensibility to a range of future plausible climate states. GCM projections are considered to estimate probabilities of the future climate states. We focus on the likely future energy mix within the region (25% of solar photovoltaic and 75% of hydropower. We also carry out a sensitivity analysis according to the storage capacity. The results show that run-of-the river power generation from this Alpine area is expected to increase although the average inflow decreases under climate change. They also show that the penetration rate is expected to increase for systems with storage capacity less than one month of average load and inversely for higher storage capacity.

    The Powersmart program at British Columbia Hydro seeks to minimize the short- and long-term energy costs to customers through the efficient or avoided use of electricity. In determining the overall financial reporting of Powersmart, four areas were reviewed in depth. The question of deferral or expensing of expenditures was examined with reference to accounting principles and industry practice in Canada and the USA. Discussion is provided on the costs that would be deferred, the amortization period of deferred expenses, and financial statement presentation. Deferral and amortization appear appropriate if the costs incurred are recoverable under future rates. The design, development, and implementation of power saving programs are outlined as well as the criteria for selection of an amortization period. At British Columbia Hydro, all Powersmart programs are treated as one type of expense and an amortization period of 7 years has been selected for all programs to simplify the accounting

    Full Text Available Reliable and safe operation of a coal-fired power plant is strongly linked to freshwater resources, and environmental problems related to water sources and wastewater discharge are challenges for power station operation. In this study, an evaluation on the basis of a wastewater thermal pollution vector is reported for the environmental impact of residual water generated and discharged in the Jiu River during the operation of thermoelectric units of the Rovinari, Turceni and Craiova coal-fired power plants in Romania. Wastewater thermal pollutant vector Plane Projection is applied for assessing the water temperature evolution in the water flow lane created downstream of each power plant wastewater outlet channel. Simulation on the basis of an Electricity of France model, and testing validation of the results for thermoelectric units of 330 MW of these power plants are presented.

  18. Authorization of nuclear power plant control room personnel: Methods and practices with emphasis on the use of simulators

    International Nuclear Information System (INIS)

    2006-07-01

    In 2002 the IAEA published a revision to Safety Guide NS-G-2.8, Recruitment, Qualification and Training of Personnel for Nuclear Power Plants. This Safety Guide provides recommendations on the authorization of designated personnel who have a direct impact on nuclear safety. The IAEA Technical Working Group on Training and Qualification of Nuclear Power Plant Personnel recommended that an additional report be prepared that provided information on the practices in Member States on the use of simulators in the authorization of control room staff. This publication has been prepared in response to that recommendation. In gathering information for the report, Member States were asked to: respond to a survey on the use of simulators and the involvement of regulatory body in operator authorization; and to complete a questionnaire on their practices in authorizing control room staff. Safety analysis and operating experience consistently indicate that human error is a major contributor to nuclear power plant (NPP) accident risk. With the recent world wide emphasis and implementation of full scope simulators for nuclear power plant personnel training, operators spend a large portion of their training time on simulators. As described in the foreword to IAEA-TECDOC-1411, Use of Control Room Simulators for Training of Nuclear Power Plant Personnel, simulators provide operators an opportunity to learn and practice the abilities that are required in accident and infrequently used plant evolutions. Because of their fidelity, full scope simulators are now used by most Member States in the authorization examinations of control room personnel. This situation is becoming more common as more plants acquire modern full scope plant referenced simulators. This publication provides information and examples based upon experience in a variety of Member States. The body of the report provides general information that represents the practices of the Member States that contributed to the

    The current article discusses institutional violence in maternity hospitals from the health workers' perspective, based on data from a study in the city of São Paulo, Brazil. Eighteen health workers from the public and private sectors were interviewed, including obstetricians, nurses, and nurse technicians. A semi-structured interview was used with questions on professional experience and the definition of violence. The analysis revealed that these health workers acknowledged the existence of discriminatory and disrespectful practices against women during prenatal care, childbirth, and the postpartum. Examples of such practices cited by interviewees included the use of pejorative slang as a form of "humor", threats, reprimands, and negligence in the management of pain. Such practices are not generally viewed by health workers as violent, but rather as the exercise of professional authority in what is considered a "difficult" context. The institutional violence is thus trivialized, disguised as purportedly good practice (i.e., "for the patient's own good"), and rendered invisible in the daily routine of care provided by maternity services.

    Thermoelectric power plants require large volumes of water for cooling, which can introduce drought vulnerability and compete with other water needs. Alternative cooling technologies, such as cooling towers and hybrid wet-dry or dry cooling, present opportunities to reduce water diversions. This case study uses a custom, geographically resolved river basin-based model for eleven river basins in the state of Texas (the Brazos and San Jacinto-Brazos, Colorado and Colorado-Brazos, Cypress, Neches, Nueces, Red, Sabine, San Jacinto, and Trinity River basins), focusing on the Brazos River basin, to analyze water availability during drought. We utilized two existing water availability models for our analysis: (1) the full execution of water rights-a scenario where each water rights holder diverts the full permitted volume with zero return flow, and (2) current conditions-a scenario reflecting actual diversions with associated return flows. Our model results show that switching the cooling technologies at power plants in the eleven analyzed river basins to less water-intensive alternative designs can potentially reduce annual water diversions by 247-703 million m 3 -enough water for 1.3-3.6 million people annually. We consider these results in a geographic context using geographic information system tools and then analyze volume reliability, which is a policymaker's metric that indicates the percentage of total demand actually supplied over a given period. This geographic and volume reliability analysis serves as a measure of drought susceptibility in response to changes in thermoelectric cooling technologies. While these water diversion savings do not alleviate all reliability concerns, the additional streamflow from the use of dry cooling alleviates drought concerns for some municipal water rights holders and might also be sufficient to uphold instream flow requirements for important bays and estuaries on the Texas Gulf coast.

    The Wabash River Integrated Methanol and Power Production from Clean Coal Technologies (IMPPCCT) project was established to evaluate integrated electrical power generation and methanol production through clean coal technologies. The project was under the leadership of ConocoPhillips Company (COP), after it acquired Gasification Engineering Corporation (GEC) and the E-Gas gasification technology from Global Energy Inc. in July 2003. The project has completed both Phase 1 and Phase 2 of development. The two project phases include the following: (1) Feasibility study and conceptual design for an integrated demonstration facility at SG Solutions LLC (SGS), previously the Wabash River Energy Limited, Gasification Facility located in West Terre Haute, Indiana, and for a fence-line commercial embodiment plant (CEP) operated at the Dow Chemical Company or Dow Corning Corporation chemical plant locations. (2) Research, development, and testing (RD&T) to define any technology gaps or critical design and integration issues. Phase 1 of this project was supported by a multi-industry team consisting of Air Products and Chemicals, Inc., The Dow Chemical Company, Dow Corning Corporation, Methanex Corporation, and Siemens Westinghouse Power Corporation, while Phase 2 was supported by Gas Technology Institute, TDA Research Inc., and Nucon International, Inc. The SGS integrated gasification combined cycle (IGCC) facility was designed, constructed, and operated under a project selected and co-funded under the Round IV of the United States Department of Energy's (DOE's) Clean Coal Technology Program. In this project, coal and/or other carbonaceous fuel feedstocks are gasified in an oxygen-blown, entrained-flow gasifier with continuous slag removal and a dry particulate removal system. The resulting product synthesis gas (syngas) is used to fuel a combustion turbine generator whose exhaust is integrated with a heat recovery steam generator to drive a refurbished steam turbine

    Full Text Available The Pilot Arno Water Accounts (PAWA project was recently funded under the Call “Preparatory Action on Development of Prevention Activities to Halt Desertification in Europe” of the Directorate- General for the Environment of the European Commission to promote preventive actions to manage water scarcity and drought phenomena and to meet one of the main goals under European environmental legislation: the effective and sustainable management of water resources. The partners involved in the implementation of the PAWA project (ISPRA, Arno River Basin Authority, SEMIDE/EMWIS will carry out a pilot initiative in the Arno River Basin, an area severely affected by water scarcity and droughts phenomena and characterized by water withdrawals and land use changes. In the area a large experience about water balance application was already performed, for example in the context of the Water Framework Directive Common Implementation Strategy. Moving from this knowledge, the objective of the project is the definition of water accounting processing based on the UN System of Environmental Economic Accounts for Water, with the final goal to optimize a list of effective measures to face water scarcity phenomena. By the end of project (March 2015 the PAWA partnership aims at preparing physical water stock accounts, using the best available data resulting from field measurements or models, on a monthly step for the period 1999–201. The quality of each dataset will be assessed; tables, maps and graphs will be produced as outputs of the projects in cooperation with local stakeholders and players of the water sector. Furthermore, water accounts will be used to assess the potential impact of various measures related to water resource efficient exploitation in the most vulnerable sub-basins; their tolerability will be tested during workshops with stakeholders. Finally, water efficiency targets for potential future integration into Arno River Basin Management Plan

    Electricity can be produced directly with reverse electrodialysis (RED) from the reversible mixing of two solutions of different salinity, for example, sea and river water. The literature published so far on RED was based on experiments with relatively small stacks with cell dimensions less than 10 × 10 cm(2). For the implementation of the RED technique, it is necessary to know the challenges associated with a larger system. In the present study we show the performance of a scaled-up RED stack, equipped with 50 cells, each measuring 25 × 75 cm(2). A single cell consists of an AEM (anion exchange membrane) and a CEM (cation exchange membrane) and therefore, the total active membrane area in the stack is 18.75 m(2). This is the largest dimension of a reverse electrodialysis stack published so far. By comparing the performance of this stack with a small stack (10 × 10 cm(2), 50 cells) it was found that the key performance parameter to maximal power density is the hydrodynamic design of the stack. The power densities of the different stacks depend on the residence time of the fluids in the stack. For the large stack this was negatively affected by the increased hydrodynamic losses due to the longer flow path. It was also found that the large stack generated more power when the sea and river water were flowing in co-current operation. Co-current flow has other advantages, the local pressure differences between sea and river water compartments are low, hence preventing leakage around the internal manifolds and through pinholes in the membranes. Low pressure differences also enable the use of very thin membranes (with low electrical resistance) as well as very open spacers (with low hydrodynamic losses) in the future. Moreover, we showed that the use of segmented electrodes increase the power output by 11%.

    The paper summarizes impacts of the Temelín Nuclear Power Plant (NPP) on the Vltava and Labe River basins. The study is based on the results of long-term monitoring carried out before the plant operation (1989-2000), and subsequently during the plant operation (2001-2005). In the first period, the main objective was to determine background radionuclide levels remaining in the environment after global fallout and due to the Chernobyl accident. A decrease in the concentrations of (90)Sr, (134)Cs and (137)Cs, which was observed before the plant operation, continued also during the subsequent period. Apart from tritium, the results of the observation did not indicate any impacts of the plant on the concentrations of activation and fission products in the hydrosphere. The annual average tritium concentrations in the Vltava River were in agreement with predicted values. The maximum annual average tritium concentration (13.5 Bq L(-1)) was observed in 2004 downstream from the wastewater discharge in the Vltava River at Solenice. Estimated radiation doses for adults due to intakes of river water as drinking water contaminated by tritium are below 0.1 microSv y(-1).

    A comprehensive study of the effects of power plant operation on the Hudson River was conducted. The study included thermal, biological, and air quality effects of existing and planned electrical generating stations. This section on thermal impacts presents a comprehensive mathematical modeling and computer simulation study of the effects of heat rejection from the plants. The overall study consisted of three major parts: near-field analysis; far-field analysis; and zone-matched near-field/far-field analysis. Near-field analyses were completed for Roseton, Danskammer, and Bowline Point Generating Stations, and near-field dilution ratios range from a low of about 2 for Bowline Point and 3 for Roseton to a maximum of 6 for both plants. The far-field analysis included a critical review of existing studies and a parametric review of operating plants. The maximum thermal load case, based on hypothetical 1974 river conditions, gives the daily maximum cross-section-averaged and 2-mile-segment-averaged water temperatures as 83.80 0 F in the vicinity of the Indian Point Station and 83.25 0 F in the vicinity of the Bowline Station. This maximum case will be significantly modified if cooling towers are used at certain units. A full analysis and discussion of these cases is presented. A study of the Hudson River striped bass population is divided into the following eight subsections: distribution of striped bass eggs, larvae, and juveniles in the Hudson River; entrainment mortality factor; intake factor; impingement; effects of discharges; compensation; model estimates of percent reduction; and Hudson River striped bass stock

    For about 100 years power is generated from hydroelectric power on the river Neckar (Federal Republic of Germany). A total hydropower capacity of about 100 megawatts already is installed at the Neckar river. In the Federal State Baden-Wuerttemberg there is certainly the potential for the construction and modernization of hydroelectric power plants. Under this aspect, the contribution under consideration reports on the reconstruction of the run-of-river power plant Schwabenheim nearby Heidelberg (Federal Republic of Germany).

  8. Short-term optimization of the new Avce pumping plant and three existing hydro power plants on the Soca river in Slovenia

    2007-01-01

    In the following years a new pumping plant Avce is going to join the existing cascade of three small-regulating-basin hydro power plants (HPPs) on the Soca river in Slovenia. The pumping plant operation will have to be synchronous to the operation of existing plants and vice versa since all four plants depend upon the same inflow and since they all belong to the same generation company that buys and sells electricity to a day-ahead electricity market. The Soca river has torrent alpine characteristics so there are doubts about the operation of the system in frequent dry seasons. As shown in this article, such questions can be effectively solved by first presenting the hydro system of four HPPs under study as a directed graph and then as a mixed integer linear program (MILP): a set of equations and inequations modeling technical issues of HPPs and a target function (the day-ahead market price) modeling the electricity market. A small and simple MILP model called Flores has been used for this study. The MILP approach requires only to specify the problem since the solution is found by using available commercial computer solvers. It can be applied on-line and it can be augmented to include also the transmission constraints, ancillary services, etc. (author)

    The Caorso nuclear power plant, which is near Piacenza and has an 875 MW boiling water reactor, has been generating electricity on a regular basis since 1978. The off-site intervention plan of the public health authorities, based on an analysis of hypothetical accidents, was approved in 1977 and subsequently revised. A study of the radiological consequences of these accidents for man and the environment indicates that the highest doses likely to be received by inhalation of 131 I would be no more than a few rem, whereas the levels of soil contamination, even at a distance of 40 km, could exceed 1 μCi/m 2 . The main problems caused by such accidents are therefore related to environmental contamination. Under the intervention plan, the provincial prefect is responsible for co-ordinating the work of all the civil, military and medical authorities. Teams from ENEL, the fire service and the local health services (USL) monitor the concentration of 131 I in the air and the exposure level, and take samples within a radius of 10 km around the site. The police and army control road traffic and are responsible, if necessary, for the evacuation of the population. A radiometry co-ordination centre (CCRI) is set up to process the readings made by the teams and provides the prefect with the technical information he requires to take decisions The local medical services (USL) run the centre where the population is assembled and monitor superficial contamination, apply initial decontamination measures, and provide medical assistance in general. The Piacenza USL also takes action by sending out its mobile radiometry laboratory, using its measurement equipment and providing logistic support to the CCRI. It is also to play a major role in informing the population in the event of an alarm. (author)

    We investigate scenarios of hydroelectric power generation for an Alpine run-of-the-river plant in 2050. To this end, we include a conversion from streamflow to energy in a hydrological model of the basin, and we introduce a set of benchmark climate scenarios to evaluate expected future production. These are a "future-like-present" scenario assuming future precipitation and temperature inputs to be statistically equivalent to those observed during the recent past at the same location, a "warmer-future" scenario, which considers an additional increase in temperature, and a "liquid-only" scenario where only liquid precipitation is admitted. In addition, two IPCC-like climatic scenarios (RCP 4.5 and RCP 8.5) are considered. Uncertainty in glaciers' volume is accounted by initializing the hydrological model with two different inventories of glaciers. Ensemble results reveal that 1) an average decrease between -40% and -19% of hydroelectric power generation in 2050 is predicted at the plant considered (with respect to present condition); 2) an average decrease between -20% and -38% of cumulative incoming streamflow volume at the plant is also predicted, again with respect to present condition; 3) these effects are associated with a strong average decrease of the volume of glaciers (between -76% and -96%, depending on the initial value considered). However, Monte Carlo simulations show that results are also prone to high uncertainties. Implications of these results for run-of-the-river plants are discussed.

    The main object of this research is to assess the water quality of Shatt Al-Arab River and its suitability for various purposes near power plants (Hartha and Najibia) through physical and chemical analysis [temperature, pH, EC, Cl-, Na+, K+, Ca+2, Mg+2, HCO3 -, NO3 -, SO 4 -2 , Fe+, total alkalinity, total hardness, biological oxygen demand (BOD5), NH4 +, and NO2 -] using water quality index (WQI), organic pollution index (OPI), sodium adsorption ratio (SAR), and percentage of sodium ion (Na%) during the dry season (August, 2016) and the wet season (January, 2017). WQI of Shatt Al-Arab falls under very poor quality during summer season, while it ranges from very poor quality to unsuitable for drinking purposes during winter season. There is a clear effect of power plants on water quality. Hartha and Najibia power plants contribute to the deterioration of water quality by increasing the percentage ratio of WQI near these plants by 13.22 and 9.69%, respectively, compared to the north sites of these plants during summer season. The percentage ratios of increased WQI near Hartha and Najibia power plants compared to the north sites of these plants are 17.93 and 15.92%, respectively, during winter season. Water quality of Shatt Al-Arab falls under a high level of organic pollution during the summer and winter seasons. There is a slight effect by the power plants on the OPI. Hartha and Najibia power plants contributed to the change of the OPI by 10% compared to the north site of Hartha power plant. According to the comparison between the SAR values which represent the suitability of water for serve irrigation purposes and SAR values of Shatt Al-Arab, all sites lie in the first class (excellent). According to Na+%, the type of surface water in the studied area lies in good class during winter season and permissible class during summer season.

    This paper investigates Momoyama hydraulic power station built on the middle reaches of the Kiso River in Uematsu-cho, Kiso-gun, Nagano Prefecture in Japan, in 1923 by relating to the feature of the building of the hydraulic power station and the architect, Shiro Sato. The hydraulic power station originally was a functional and industrial building which puts a priority on the efficiency of business economy, at the same time it was often required to present a beautiful appearance. The building of Momoyama hydraulic power station was founded on the crane girder structure covered with reinforced concrete(RC) walls. A Hat roof of RC slab was applied to the roof of the building. It was generally designed in Neo-Gothic style. More specifically, however, the wall surface was designed in church style and the upper part was like a castle in the middle ages. Therefore the total design was eclectic. The outer surfaces of the building were remained to be bare concrete as cast. Such a multiple building symbolizes the situation of Japanes architecture in the 1920s. 4 figs.

    A survey of the transport of spent fuel in and from Germany during the last 20 years is presented. The spent fuel is now transported from the German nuclear power facilities to the reprocessing plants in France and the United Kingdom. In the past, there were also shipments to the former reprocessing plant WAK Karlsruhe (Germany), to the long-term storage facility CLAB (Sweden) and also from the former German Democratic Republic to the USSR. The transport of the spent fuel is carried out in specially built flasks requiring an extensive quality assurance programme. Due to the heavy weight of these packages, the shipments are mostly carried out by rail, but also by road and sea. An overview is given of the following matters: (i) quantities of spent fuel transport, (ii) organisation of transport (iii) licensing matters, and (iv) reported incidents. In addition, an analysis is included of the radiation exposure for normal conditions of transport, especially of the transport workers. Difficulties and hindrances during transport are also reported.

    Beginning at the turn of the century, Chapter One reconstructs the process by which the Provincial Government of Quebec sold--individually, outright, and cheaply--the waterfalls and rapids strung out along the length of the Saguenay River. The small-scale Canadian power projects stalled, however, for want of capital or power customers in a remote North American region. A major shift in developmental scale ensues in Chapter Two as a Canadian who owned riparian rights, Thomas "Carbide" Willson, uncorks a genie of American capital in industrialist J. B. Duke. While Duke was invited to participate in the Saguenay's development as a third party, Chapter Three describes how the aggressive New York trader seizes the entire length of the river for his exclusive use. Chapter Four recounts the unexpectedly stiff resistance to the industrial plans of Duke's lieutenants by a young French-Canadian engineer named Arthur Amos, head of Quebec's newly established Hydraulic Service. Stymied in Quebec City, Duke nonetheless proves remarkably agile in the broader theater of multinational enterprise. As Chapter Five documents, Duke succeeds in rounding up an array of industrial power customers to justify the enormous cost of his dams, most notably Delaware-based explosives manufacturer E. I du Pont de Nemours Powder Company. Ultimately Du Pont gets cold feet, and Duke's giant electrochemical scheme collapses around him at the end of 1915. Only after 1920, in Chapter Six, is Duke able to proceed with his project in a changed political and business climate of the postwar period. Contemplating aluminum manufacture by his own company, in Chapter Seven, he attempts to procure the requisite supply of high grade bauxite. But he encounters ferocious competition for possession of the essential raw material. Choosing to merge rather than fight, Duke and Alcoa's President Arthur Vining Davis ally in 1925. Their deal sealed, the two businessmen send their Canadian lawyer to Quebec City to sidestep

    Laboratory and field simulations of the discharge plume entrainment of phytoplankton, zooplankton and fish were carried out at the Indian Point Nuclear Station, Hudson River estuary, USA. Phytoplankton assemblages studied on two dates produced different response patterns measured as photosynthetic activity. Chlorophyll-a levels did not change following simulated entrainment. Possible explanations for the differences are discussed. The two abundant copepods Acartia tonsa and Eurytemorta affinis appear to tolerate exposure to discharge plume ΔT without adverse effects. Copepods subjected to plume entrainment may suffer considerable mortality during periods of condenser chlorination. In general, the amphipod Gammarus spp. did not appear to suffer significant mortality during simulated entrainment. Juvenile striped bass, Morone saxatilis, were not affected by simulated plume transit before and during plant condenser chlorination; however, a simulated ''worst possible case'' plume ΔT produced statistically significant moralities.

    1975-01-01

    The Gundremmingen Nuclear Power Plant (boiling water reactor, 237 MW(e)), on the Upper Danube, has been in operation since 1967. Radiological data have been collected throughout its period of operation. The behaviour of the radioactive waste products in the ecological system of the Upper Danube (water, sediments, suspended solids, water-plants, fish) has been analysed in connection with environmental contamination, the uptake capacity of the Danube, and the possible pathways to man. As a result of the investigations, it seems possible to build further nuclear power plants on the Danube, if their rates of release of radioactivity are similar to those at Gundremmingen. (author)

    Distribution of 'supplementary reader on nuclear power: Challenge! Nuclear power world' issued in 2010 and 'supplementary reader on radiation' issued in October 2011 was shelved in June 2012 by the administrative project review with revised policy of nuclear education for nuclear power promotion reflected. Great East Japan Earthquake and Fukushima Daiichi Nuclear Power Accident brought about great effects and change on fundamental conditions of citizen's life as well as national consciousness of future society in Japan. Reconsideration of scientific education should be needed taking account how to recognize 'scientific literacy' and 'scientific communication'. This article discussed nuclear power problem related with supplementary reader and nuclear power education so as to establish science education framework for 'scientific literacy' for citizen. Preparation of nuclear power education at junior high school according to guideline of new course of study was reviewed and then 'scientific literacy' based on British science higher level student textbook for public understanding of science in society was described for reference, which suggested some problem in science education in Japan although social background was different.

  3. From two reports; authorization of 17 nuclear power plants in '81 and '82: by the year 2000, underground and offshore siting should be possible

    International Nuclear Information System (INIS)

    1981-01-01

    The Ministry of International Trade and Industry has published ''Electric power facility plan, 1981'', and set the target of the installed capacity of nuclear power in 1990 at 51,000 MW. In order to reach this target, the Ministry must submit the electrical power facility plan involving 20,000 MW to the Electric Power Resource Development Coordination Council for the required authorization. Meanwhile, the Central Research Institute for Electric Power Industry has engaged in the assessment of long term electric power needs for three years, and completed the report ''Prospects of electric power supply and demand until the year 2000, long term energy strategy''. The conclusions are that nuclear energy must be actively promoted, and that the limitation of land space and the geological conditions in Japan must be overcome, and for the purpose, the technologies of locating nuclear power stations underground and offshore should be developed. The summaries of these two reports are given. 17 units are planned to be submitted to the ERDCC for the approval in the years 1981 and 1982. But the actual situation is severe because it takes long years from the application for construction to the start of operation of nuclear power plants. (Kako, I.)

    Muniz, I.P.; Bendiksen, E.; Erikstad, L.; Reitan, O.

    1997-12-31

    This report discusses the possible environmental consequences of a planned hydroelectric power development of the river Grunnaai, Norway. The consequences are found to be small, provided the proper counter measures are taken. Without counter measures, there may be moderate consequences on fish populations and botanical conditions, directly dependent on the changed water flow. The greatest value of the area concerned lies in its unspoiled wilderness character. There are extensive lists of birds and mammals and plant species registered in the river valley. 51 refs., 7 figs., 4 tabs.

  5. Transport behavior of radioactive caesium from forests contaminated by the Fukushima Dai-ichi nuclear power plant accident through river water system

    2014-07-01

    Japan Atomic Energy Agency (JAEA) has carried out 'the project on the Long-term Assessment of Transport of Radioactive Contaminant in the Environment of Fukushima (F-TRACE project)' since the end of 2012. Radioactive caesium (Cs) has been distributed by the fallout by the Fukushima Dai-ichi Nuclear Power Plant (1F-NPP) accident, and forests in mountain areas have large amount of inventory of radioactive Cs and cover relatively large part of contaminated area of Fukushima. In this project, the transport behavior of radioactive Cs from the forests to biosphere and sea is evaluated by computer simulation based on the results of field observation and laboratory experiments. The results are used to predict evolution of effective dose of the residents in the affected area due to the transport, specify the dominant pathway of Cs, and propose effective methodology to constrain the transport along the pathway. This study reports the specific transport behavior of Cs observed in the basins of five rivers by means of the field investigation and laboratory experiments during the first year of the project. Radioactive Cs located at the crown was considered to be transported to the soil surface by litter fall, stem flow and canopy drip in the Japanese cedar tree forests. Even after two years since the accident, more than 90% of radioactive Cs was still been remained within 5 cm depth from the top of the soil, indicating that the distribution coefficient of radioactive Cs onto the specific minerals such as clay was significantly high. In the river, relatively higher dose rate was observed at the flood channel where fine-grained soil particles were trapped by growing vegetation, while low dose rate was observed beside the river channel where coarse sand or gravel accumulated. The results suggested that fine-grained soil particles containing minerals adsorbing large amount of radioactive Cs were transported in high water level and trapped by the vegetation. In the dam

  7. Has the Federal Government the power to instruct State authorities in procedures under the Atomic Energy Act

    International Nuclear Information System (INIS)

    Ost, W.; Pelzer, N.

    1979-01-01

    The differences in opinion which have emerged between the Federal Government and ministers of the State of North Rhine-Westphalia about further permits to be issued for construction of the SNR 300 fast breeder reactor at Kalkar have raised the question of whether the Federal Government has the right to issue directives to a state authority to grant a permit. Close examination of the legal aspects indicates that hardly any literature and no court decisions are as yet available on this problem, because it has never played a role so far. However, it is undisputed that there is such a right to give instructions. Under the Constitution and the Atomic Energy Act the state authorities are responsible for granting permits, but only as agents acting on behalf of the federal authority. Such instructions must be in accordance with the Atomic Energy Act and the objective sought must be lawful for the instructions to be effective. (orig.) [de

  8. Do rivers really obey power-laws? Using continuous high resolution measurements to define bankfull channel and evaluate downstream hydraulic-scaling over large changes in drainage area

    Science.gov (United States)

    Scher, C.; Tennant, C.; Larsen, L.; Bellugi, D. G.

    2016-12-01

    Advances in remote-sensing technology allow for cost-effective, accurate, high-resolution mapping of river-channel topography and shallow aquatic bathymetry over large spatial scales. A combination of near-infrared and green spectra airborne laser swath mapping was used to map river channel bathymetry and watershed geometry over 90+ river-kilometers (75-1175 km2) of the Greys River in Wyoming. The day of flight wetted channel was identified from green LiDAR returns, and more than 1800 valley-bottom cross-sections were extracted at regular 50-m intervals. The bankfull channel geometry was identified using a "watershed-based" algorithm that incrementally filled local minima to a "spill" point, thereby constraining areas of local convergence and delineating all the potential channels along the cross-section for each distinct "spill stage." Multiple potential channels in alluvial floodplains and lack of clearly defined channel banks in bedrock reaches challenge identification of the bankfull channel based on topology alone. Here we combine a variety of topological measures, geometrical considerations, and stage levels to define a stage-dependent bankfull channel geometry, and compare the results with day of flight wetted channel data. Initial results suggest that channel hydraulic geometry and basin hydrology power-law scaling may not accurately capture downstream channel adjustments for rivers draining complex mountain topography.

  9. The impact of nuclear power stations and of a fuel reprocessing plant on the Rhone river and its prodelta

    1992-01-01

    The Rhone, with its 6 nuclear sites (17 reactors of various types and a fuel reprocessing unit), presents a relevant example for comparing the impact of these various installations on the aquatic ecosystem. Artificial radioactivity (γ emitters, Pu, 3 H, 90 Sr...) and natural radioactivity are monitored in sediments and various living organisms in the river and its prodelta. A summary of the radioecological procedure is given and illustrated with examples selected from results obtained over the last fifteen years (data resulting from about 7500 samples taken up- and downstream of the installations and in the prodelta). The evolution of results obtained during this period by γ spectrometry on fish up- and downstream of the nuclear power station at Bugey and the Marcoule fuel reprocessing unit is presented. The role of aquatic vegetation as indicator of radiocontamination is also illustrated. The evolution in the concentration levels of γ emitting artificial radionuclides in sediments and mussels in the prodelta is commented on in order to show the global radioecological impact of the Rhone in the Mediterranean sea. The analyses presented show that it is possible to quantify the influence of each source term on the total artificial radioactivity of the compartments of the ecosystem. The source terms are atmospheric fallout from early nuclear weapon tests and of the Chernobyl accident, and liquid wastes of various composition from nuclear installations

    1977-07-01

    Because of the location of the Bowline, Roseton, and Indian Point power generating facilities in the low-salinity zone of the Hudson estuary, operation of these plants with the present once-through cooling systems will adversely influence the fish populations that use the area for spawning and initial periods of growth and development. Recruitment rates and standing crops of several fish species may be lowered in response to the increased mortality caused by entrainment of nonscreenable eggs and larvae and by impingement of screenable young of the year. Entrainment and impingement data are particularly relevant for assessing which fish species have the greatest potential for being adversely affected by operation of Bowline, Roseton, and Indian Point with once-through cooling. These data from each of these three plants suggest that the six species that merit the greatest consideration are striped bass, white perch, tomcod, alewife, blueback herring, and bay anchovy. Two points of view are available for assessing the relative importance of the fish species in the Hudson River. From the fisheries point of view, the only two species of major importance are striped bass and shad. From the fish-community and ecosystem point of view, the dominant species, as determined by seasonal and regional standing crops (in numbers and biomass per hectare), are the six species most commonly entrained and impinged, namely, striped bass, white perch, tomcod, alewife, blueback herring, and anchovy

  11. Report and recommendations in the matter of British Columbia Hydro and Power Authority and an inquiry into a Heritage Contract for British Columbia Hydro and Power Authority's existing generation resources and regarding stepped rates and transmission access

    2003-01-01

    Under British Columbia's new energy plan, the BC Utilities Commission made recommendations on two main policy initiatives regarding regulation of BC Hydro. The first involved a Heritage Contract that would ensure any benefits attributable to the existing low-cost generation of BC Hydro would be secured for British Columbians. The Heritage Contract had the support of all participants. The proposal was based on the revenue required by Generation to meet the cost of supplying the energy of Heritage Resources to Distribution. The second recommendation involved a stepped rate structure for large commercial and industrial customers to encourage a more efficient use of energy resources and private investments in new generation. It also recommends concurrent implementation of time-of-use rates. BC Hydro had also proposed a significant change in the determination and disposition of Trade Income between BC Hydro and Powerex. The agreement stipulated that Trade Income would no longer include revenues from the sale of surplus power, except for profits realized by Powerex after paying BC Hydro an indexed price for surplus power. All Trade income up to $200 million would accrue to the ratepayers. This report presents 3 alternatives to the Trade Income proposal and several others recommendations dealing with transmission voltage customers and generation access, legislation, regulation and special directions. The report identified a schedule for implementation of retail access by the end of 2004. 9 appendices

  12. Authority, Power and Reason of State in the Theater of Antonio Enríquez Gómez

    Directory of Open Access Journals (Sweden)

    Manuel Calderón Calderón

    2017-06-01

    Full Text Available Comedies of political content written by Antonio Enríquez Gómez reflect, through the analysis of its four recurring themes —the dichotomy between law and power, the reason of state, the law enforcement from a political point of view and forgiveness—, the outlines of the nascent Leviathan or modern state. Although the patriarchal relationship between the Monarch and his people is based on a iusnaturalist conception, love should be subject to the effectiveness in the exercise of power. The characters in this theatre sometimes hesitate between Aristotelian-Thomistic rationalism and Machiavellian-Hobbesian reason of state and, on other occasions, they oppose the people’s strength, risk and will to the divine reason of Law. In the context of the Hispanic Monarchy crisis, Enríquez Gómez’s critics are not limited to Government representatives and civil servants, but also include the Church and common people (Third State.

  14. Final environmental assessment for a refinement of the power delivery component of the Southern Nevada Water Authority Treatment and Transmission Facility

    International Nuclear Information System (INIS)

    1998-07-01

    The Southern Nevada Water Authority (SNWA) is designing and constructing a system of regional water supply facilities to meet current and projected water demands and increase system reliability. The existing Southern Nevada Water system is being upgraded with a number of improvements to increase the capacity of the system. However, even the expanded system is expected to be unable to meet projected peak daily water demands by the year 1999. As a result, new facilities are being designed and constructed to operate in conjunction with the upgraded Southern Nevada Water system. These new facilities, known as the Southern Nevada Water Authority Treatment and Transmission Facility (SNWA-TTF), include four primary components: a new raw water intake; new transmission facilities including below ground pipelines, tunnels, and above ground pumping stations; a water treatment facility; and new power supply facilities. Because existing power supplies would not be adequate for the new water treatment facilities, new power facilities, consisting of two new 230 kV-69 kV substations and new 69 and 230 kV power lines, are being constructed. This environmental assessment is specifically on the new power facilities

    1997-11-01

    The report concerns an investigation done in Norway on environmental consequences of hydroelectric power development in the Dokka river. This development has reduced the water flow through the Dokka delta to about 50% of its natural level. The biological effect of the reduction has been studied in the period from 1987 to 1990, comprising two years before and two years after the reduction. Sedimentation, water chemistry, planktonic and littoral crustaceans and bottom fauna have been studied. 223 refs., 58 figs., 9 tabs.

    The Kursk TETs-1 heating and electric power plant is discussed as an illustration of preventing thermal contamination of its water supply (River Seim) by circulating water. An effective water supply system is taken to be one for which the overheating of the water at a monitoring site (near the outlet location) does not exceed an approved level for the water use conditions. The required cooling capacity of a spray pond for circulating and flow-through water supplies is determined.

  17. Saga of Clinch River

    International Nuclear Information System (INIS)

    Young, W.H.

    1984-01-01

    An epic struggle in the US Congress between what the author calls the forces of transcendence and the forces of experience over development of a breeder reactor for electric power generation is described in this article. The project was started by President Nixon, survived repeated attacks under President Carter, and ironically succumbed under a strong supporter, President Reagan, as a result of an unlikely coalition of conservative organizations and Republican politicians. The broader meanings of the demise of the Clinch River project are examined on several levels, examining the significance for the nation's energy future and for the nation's political future

    The aim of this study was to carry out theoretical investigations of power frequency magnetic fields (MFs), produced inside and outside the domain of urban 110-kV power substations and to establish a correspondence between the levels of the fields and the specified population limits as defined by Ukrainian regulations. The fields produced by high-voltage substations were studied based on the application of the numerical finite element methodology. The investigations have shown that magnetic flux density values calculated inside and outside the considered 110-kV power substations do not reach the exposure limits specified by the Ukrainian regulations (1750 μT) and by international guidelines (ICNIRP 2010). Inside the domain of the substation, the maximum value of MFs was found under the 10-kV bus-bars and it equalled 420 μT. (authors)

    The aim of this article is to show that in the context of sustainable development, coal and its downstream power generation industry could complement petroleum and hydroelectric industries in the national power generation scheme. The continued utilization of coal in power generation schemes in the world as well as environmental pollution caused by other fossil fuels were examined. These were presented as justifications for the proposed reintegration of coal as a complement to hydropower and oil/gas sources of electric energy in Nigeria. The scheme of power generation in the Oji-River thermal station was reviewed to enhance the appreciation of the retrofit models to be presented for the revitalization of the plant. Subsequently, two sustainable development retrofit models were considered for the revitalization of the Oji-River thermal power station and enhanced industrial civilization of the Oji neighbourhood. To ensure self-sufficiency, the paper shows how the two retrofit models depend on abundant locally available resources, namely, coal, limestone, water and air.

    A multifilament nylon net of 0.95-cm bar mesh was deployed as a physical barrier to fish in front of the Bowline Point power plant cooling water intake on the Hudson River from 1976 to 1985. The barrier net was deployed during the historical peak impingement months of October-May. The primary species impinged on the intake screens during this period were young-of-year and yearling white perch, striped bass, rainbow smelt, alewife, blue-back herring, and American shad, generally ranging from 5 to 10 cm in total length. When the barrier net was deployed, median impingement of all fish was 91% lower than during comparable periods before the net was installed. A mark-recapture population estimate indicated that 230,000 yearling striped bass and white perch were in the embayment outside the net in April 1982; over a 9-d study period, only 1.6% of this estimated population was impinged. Concurrent survival probability studies of fish marked and released at locations inside and outside the barrier net showed that fish released inside had 72% lower survival (P

    Steelhead (Oncorhynchus mykiss) populations have declined throughout their range in the last century and many populations, including those of the Snake River Basin are listed under the Endangered Species Act of 1973. The reasons for their decline are many and complex, but include habitat loss and degradation, overharvesting, and dam construction. The 2008 Biological Opinion calls for an increase in the abundance of female steelhead through an increase in iteroparity (i.e., repeat spawning) and this can be realized through a combination of reconditioning and in-river survival of migrating kelts. The goal of this study is to provide the data necessary to inform fisheries managers and dam operators of Snake River kelt migration patterns, survival, and routes of dam passage. Steelhead kelts (n = 487) were captured and implanted with acoustic transmitters and passive integrated transponder (PIT)-tags at the Lower Granite Dam (LGR) Juvenile Fish Facility and at weirs located in tributaries of the Snake and Clearwater rivers upstream of LGR. Kelts were monitored as they moved downstream through the Federal Columbia River Power System (FCRPS) by 15 autonomous and 3 cabled acoustic receiver arrays. Cabled receiver arrays deployed on the dam faces allowed for three-dimensional tracking of fish as they approached the dam face and were used to determine the route of dam passage. Overall, 27.3% of the kelts tagged in this study successfully migrated to Martin Bluff (rkm 126, as measured from the mouth of the Columbia River), which is located downstream of all FCRPS dams. Within individual river reaches, survival per kilometer estimates ranged from 0.958 to 0.999; the lowest estimates were observed in the immediate forebay of FCRPS dams. Steelhead kelts tagged in this study passed over the spillway routes (spillway weirs, traditional spill bays) in greater proportions and survived at higher rates compared to the few fish passed through powerhouse routes (turbines and juvenile

    Full Text Available This article explores the ongoing conflict over state forest land between the local population and the State Forestry Corporation (SFC in a village in upland Central Java with regard to authority formation. It looks at how different agents draw on different sources of authority in the course of the conflict and its negotiations. The principal questions are to what kind of sources of authority villagers refer to and how the formation of authority informs the relations between the state and society in the land dispute. The article is based on 11 months of ethnographic fieldwork and focuses on the central figure of Pak Wahid who took a leading position in the forest land dispute and in mobilising peasants in the village. The article argues that in post-Suharto Java, leadership in the struggle for state forest land at the village level is embedded in the interaction of Javanese ideas of power and authority as well as administrative authority. Due to political and institutional reforms, new sources of authority could be invoked while there are no real changes in the power relations within the village or between the SFC and the villagers. ----- Dieser Artikel untersucht den anhaltenden Konflikt um staatliche Waldflächen zwischen der lokalen Bevölkerung und der State Forestry Corporation (SFC in einem Dorf im Hochland von Zentral- Java in Bezug auf die Entwicklung von Autorität. Es wird untersucht, wie sich unterschiedliche AkteurInnen im Rahmen des Konflikts und dessen Verhandlung auf unterschiedliche Bezugsquellen von Autorität beziehen. Die zentralen Forschungsfragen in diesem Zusammenhang sind, auf welche Bezugsquellen von Autorität sich DorfbewohnerInnen beziehen und wie die Entwicklung von Autorität die Beziehungen zwischen Staat und Gesellschaft im Rahmen des Landkonflikts beeinflusst. Der Artikel basiert auf einer 11-monatigen ethnografischen Feldforschung und fokussiert auf die Person von Pak Wahid, der eine Schlüsselrolle im Konflikt

    Migration behavior of several atmospherically-derived radionuclides in a river watershed was studied. A main interest was in their relocation from the ground soil of the watershed to a downstream region through a river. Studied radionuclides are: {sup 137}Cs generated by weapon tests in the atmosphere; {sup 210}Pb and {sup 7}Be of naturally occurring radionuclides; {sup 137}Cs, {sup 90}Sr, {sup 239,240}Pu and {sup 241}Am released by the Chernobyl nuclear power plant accident. Dominance of the form in suspended solid in river water (particulate form) was qualified for the radionuclides in the Kuji river watershed. An importance of discharge in flooding was also confirmed. A historical budget analysis for weapon test derived {sup 137}Cs was presented for the Hi-i river watershed and its accompanied lake sediment (Lake Shinji). The work afforded a scheme of a fate of {sup 137}Cs after falling on the ground soil and on the lake surface. Several controlling factors, which can influence on the chemical form of radionuclides discharged to a river, were also investigated in the vicinity of the Chernobyl nuclear power plant. A special attention was paid on the association of the radionuclides with dissolved species in water. Preferential association of Pu and Am isotopes to a large molecular size of dissolved matrices, probably of humic substances, was suggested. (author)

    The vertical distribution of net zooplankton in head-water of Krasnoyarsk hydroelectric power station and its horizontal distribution in the tail-water were studied during two years in winter and summer seasons. In order to distinguish living and dead individuals the special staining was used. It was revealed that on average 77% of living plankton pass through high-head dam with deep water scoop to the tailwater. While passing through dam aggregates some individuals of the reservoir plankton are traumatized and die, that results in some increase of portion of dead individuals in the tail water near dam (from 3 to 6%). Alive zooplankton passed through the dam aggregates is eliminated under the Upper Yenisei highly turbulent conditions. There is approximately 10% of it in 32 km from the dam if compare with biomass in 20-40 m layer of reservoir, the portion of dead increases to 11%. The biomass of zooplankton suspended in the water column of the tail-water sometimes increases (till > 1 g/m3) due to large Copepoda Heteroscope borealis, which inhabits near-bottom and near-shore river zones and can be found in the central part of the river during reproductive period. Limnetic zooplankton from the reservoir cannot be considered as important food for planktivores in the tail-water.

    Our study in the Journal of Sports Sciences was originally designed to test whether the bar-velocity is a precise indicator of the power training intensity (i.e., optimum loads) in different exercises commonly included in athletes' training programs. Furthermore, we presented secondary findings, related to the actual results obtained in our assessments. As a cross-sectional study with clear objectives, we focused on discussing issues and applications pertaining to neuromuscular training interventions, such as: (1) describing the advantages of using bar-velocities to control the power training intensity, (2) defining a range of loads capable of maximizing the power production in certain ballistic and traditional exercises, and (3) revealing the differences between these exercises and the respective implications for training. Fundamentally, we did not produce a mechanistic investigation and were very accurate and consistent in reporting our data, collected under rigorous and well-established experimental conditions. Here we provide our point-by-point comments to the concerns raised in the "Letter to the Editor", along with some theoretical explanations about the secondary findings reported by the authors of the Letter. To better understand the nature and purposes of our experiment, we also present a series of practical examples and review previous investigations involving the "bar-power" approach.

  1. Analysis of replies to an IAEA questionnaire on procedures for accreditation of training programmes and for authorization and licensing of nuclear power plant operations personnel

    International Nuclear Information System (INIS)

    1991-06-01

    The intent of this survey was to gather data and present results to facilitate the international exchange of information and experience in this field. This was accomplished using a questionnaire developed by the IAEA that was sent in September, 1989 to the thirty-one Member States having nuclear power plants operating or under construction. Of these, twenty-one responses were received. The questionnaire was constructed in two parts: (1) Accreditation of Training Programmes; and (2) Authorization and (Formal) Licensing of Operations Personnel. The analysis was conducted by IAEA staff with the assistance of consultants and resulted in an identification of the commonalities and differences in approach on these issues. An advisory group subsequently considered this analysis, interpreted the results relative to the original responses, and reached conclusions that are contained in this document

    Full Text Available The renewable energy emerged as a solution to the environmental problems caused by the conventional sources of energy. Small hydropower (SHP is claimed to cause negligible effects on the ecosystem, although some environmental values are threatened and maintenance of an adequate water quality should be ensured. This work provides a characterization of the water quality status in a river stretch around a SHP plant on river Lérez, northwest Spain, for four years after its construction. The ecological and chemical status of the water as well as the ecological quality of the riparian habitat, were used as measures of quality. Data were compared with the water quality requirements. The variations in the quality parameters were analyzed over time and over the river sections with respect to the SHP plant elements. Two years after construction, the temperature and dissolved oxygen values achieved conditions for salmonid water and close to the reference condition, while pH values were low. The Iberian Biological Monitoring Working Party (IBMWP index showed a positive trend from two years after the construction and stabilized at “unpolluted or not considerably altered water”. Quality parameters did not present significant differences between sampling points. The SHP plant construction momentarily altered the quality characteristics of the water.

  3. Aspects of authority and power illustrated by the Portuguese canonization celebrations of Ignatius of Loyola and of Francis Javier Cristina Osswald Universidade Nova de Lisboa

    Directory of Open Access Journals (Sweden)

    Cristina Osswald

    2013-05-01

    Full Text Available The canonization of the founder of a Catholic religious order constitutes a milestone in the affirmation of authority by that order. As concerns to the Society of Jesus, it was a double canonization. Such an uncommon fact as this, clearly both demonstrates the power the Society had at the time at the Curia, and explains its intention of celebrating the auto-glorification. Its scenography, thus, aimed more to praise the triumph of the Society of Jesus through the use of allegorical figures such as Religion, Fame, Honour or Pomp, than anything else. The iconography of such festivities framed the first Jesuits saints within the history of the Society. Thus, the Portuguese jesuits paid homage, by means of the staging, to the beatified ones, the first jesuits and the martyrs. Moreover, the set pointed out its main devotions, characteristics and activities such as missionary work and teaching activities. Often canonizations of a certain figure were intimately related to political power in Early Modern Time. Therefore, Portuguese Jesuit festivities exalted, with a great vigour, feelings of nationalism during the Iberian Union’s time. In order to transmit the various aims, the organizers did not hesitate to use all Baroque celebrative resources (poetry, theatre, dance, music and visual arts. In other words, particularly luxurious and grandiose celebrations, including light, sound, colour, and odour spectacles or events (reference be made to the vases with perfume inside the churches took place by that time.

    An aerial radiological survey was conducted over the Oyster Creek Nuclear Power Plant in Forked River, New Jersey, during the period September 18 through September 24, 1992. The survey was conducted at an altitude of 150 feet (46 meters) over a 26-square-mile (67-square-kilometer) area centered on the power station. The purpose of the survey was to document the terrestrial gamma radiation environment of the Oyster Creek Nuclear Power plant and surrounding area. The results of the aerial survey are reported as inferred gamma radiation exposure rates at 1 meter above ground level in the form of a contour map. Outside the plant boundary, exposure rates were found to vary between 4 and 10 microroentgens per hour and were attributed to naturally-occurring uranium, thorium, and radioactive potassium gamma emitters. The aerial data were compared to ground-based benchmark exposure rate measurements and radionuclide assays of soil samples obtained within the survey boundary. The ground-based measurements were found to be in good agreement with those inferred from the aerial measuring system. A previous survey of the power plant was conducted in August 1969 during its initial startup phase. Exposure rates and radioactive isotopes revealed in both surveys were consistent and within normal terrestrial background levels

    and creativity suggests that when managers give people the opportunity to gain power and explicate that there is reason to be more creative, people will show a boost in creative behaviour. Moreover, this process works best in unstable power hierarchies, which implies that power is treated as a negotiable....... It is thus a central point that power is not necessarily something that breaks down and represses. On the contrary, an explicit focus on the dynamics of power in relation to creativity can be productive for the organisation. Our main focus is to elaborate the implications of this for practice and theory...

  2. Feasibility study of upgrading Byllesby and Buck power plants on the New River in the Commonwealth of Virginia

    Energy Technology Data Exchange (ETDEWEB)

    1979-05-01

    The feasibility of upgrading alternatives of the 66-year-old Byllesby and Buck hydroelectric developments located on the New River in Virginia was investigated. Evaluation of technical, economic and environmental factors led to the conclusion that modernization of the plants could result in an annual generation increase of 20.2 GWh at a cost of $6.1 million and with a benefit-cost ratio of 2.32. The recommended retrofitting includes replacing existing runners with new, more efficiently designed runners, modifying draft tube and wicker gate, and rewinding the generators. (LCL)

    Full Text Available Energy is made operational in an industry with great spectrum and impact on world and local economic activities, as it enables the generation production of various products and facilitates human activities, such as transportation, comfort and leisure. The figures in the industry are exceedingly large regarding supply, consumption, financial volume, and influence on individuals, and social imaginarium. Thus, it is understood that Energy defines the course of society, whether positive or negative. The construction of dams on the Madeira River will be examined from this theoretical framework.

    The purpose of the project described in this report was to prepare an operative tool for making decisions about the operation of the power system on the river Otra (Norway) with regard to how this operation might affect the various users of the river system. Above all this affects fish, outdoor life and esthetic values. The connection between water quality and volume of discharge has been examined in a sub project. How suitable parts of the river are as habitats for trout has been simulated on a computer. From field investigation it is concluded that near the Steinfoss power station the physical conditions for trout depend on the operation of the river system.

  5. Channel Planform Dynamics Monitoring and Channel Stability Assessment in Two Sediment-Rich Rivers in Taiwan

    Full Text Available Recurrent flood events induced by typhoons are powerful agents to modify channel morphology in Taiwan’s rivers. Frequent channel migrations reflect highly sensitive valley floors and increase the risk to infrastructure and residents along rivers. Therefore, monitoring channel planforms is essential for analyzing channel stability as well as improving river management. This study analyzed annual channel changes along two sediment-rich rivers, the Zhuoshui River and the Gaoping River, from 2008 to 2015 based on satellite images of FORMOSAT-2. Channel areas were digitized from mid-catchment to river mouth (~90 km. Channel stability for reaches was assessed through analyzing the changes of river indices including braid index, active channel width, and channel activity. In general, the valley width plays a key role in braided degree, active channel width, and channel activity. These indices increase as the valley width expands whereas the braid index decreases slightly close to the river mouth due to the change of river types. This downstream pattern in the Zhuoshui River was interrupted by hydraulic construction which resulted in limited changes downstream from the weir, due to the lack of water and sediment supply. A 200-year flood, Typhoon Morakot in 2009, induced significant changes in the two rivers. The highly active landscape in Taiwan results in very sensitive channels compared to other regions. An integrated Sensitivity Index was proposed for identifying unstable reaches, which could be a useful reference for river authorities when making priorities in river regulation strategy. This study shows that satellite image monitoring coupled with river indices analysis could be an effective tool to evaluate spatial and temporal changes in channel stability in highly dynamic river systems.

    Actual experience gained during the post-construction testing of three nuclear power plants, under the USAEC Power Reactor Demonstration Program, may permit some generalizations concerning this phase of plant construction and operation. The three plants, Elk River Reactor (ERR), Hallam Nuclear Power Facility (HNPF), and the Piqua Nuclear Power Facility (PNPF), represent three different reactor concepts: natural-circulation boiling water, sodiumgraphite, and organic cooled and moderated, respectively. The post-construction testing period included the time between the end of construction (erection of structures and installation of equipment) and the beginning of power operation (generation of significant net electrical power). The tests were intended to: (a) verify the performance characteristics of the as-installed equipment; (b) obtain initial criticality and reactivity coefficient measurements; and (c) determine reactor physics and plant performance characteristics at a sequence of increasing power levels. .The experience gained can be reported in six separate but interrelated categories: (1) schedule; (2) costs; (3) staffing requirements; (4) procedures; (5) equipment performance (including malfunctions); and (6) actual, as compared to predicted, system performance characteristics. The average project staffing, including craftsmen, operators, supervisors, technical support and trainees, was approximately 50 for ERR, 115 for HNPF, and 60 for PNPF. Detailed written Pre-operational Test Procedures were prepared for each major component and system. To the maximum possible extent, all tests were performed before fuel loading and operation of the integrated plant. Authorization procedures (duplicates of the licensing procedures for non-USAEC-owned plants) were in progress during almost all of the post-construction testing periods. The time required for post-construction testing of each of these plants significantly exceeded the original estimates. The tests disclosed

  7. The Mythical Power of the Dual River-System of the Carpathian Basin: The Notion of a Hungarian Mesopotamia

    Directory of Open Access Journals (Sweden)

    Róbert Keményfi

    2016-01-01

    Full Text Available Gyula Prinz is responsible for the notion of “Magyar Mezopotámia” [Hungarian Mesopotamia]. The natural basis for this idea is that Hungarian culture developed on the surface of an alluvial plains area. This sort of natural environment was the precondition of great civilizations based on agriculture. In other words, the intrinsic Duna-Tisza [Danubius-Tibiscus] river structure, which is similar to that of the rivers Tigris and Euphrates, would elevate Hungary to the status of a mesopotamic country. This is how the central Hungarian area could become the distributing core of culture and how this culture could be radiated towards the neighboring peoples who also lived together with us in the Carpathian Basin. Our “cultural power” therefore “elevated” the cultural level of other peoples who lived with us on the edges of the Carpathian Basin. Accordingly, the end, or the borderline, of the highbrow “core culture” is located where the territory populated by Hungarians ends, or where the plains area shifts into the Carpathian Mountains.

    From symposinm on environmentl behavior of radionuclides released in the nuclear industry; Aix-en-Provence, France (14 May 1973). The location of nuclear power plants by rivers whose waters are used for irrigation and industrial and domestic consumption necessities a profound study of the river-irrigated soil- ground water system. Mechanisms of radionuclide transport in cultivated soil are considered under three principal aspects: the effect of the quality of the river water, of the irrigation channels, and of the ground water level on the mobility of the radionuclides in the soil; the influence of the type of soil (the four types of soils considered are acid brown soil, calcic brown soil, chalky brown soil, and chalky alluvial soil); and the distribution of radionuclides in the soil (hydrosoluble forms can contminate the ground water level and these are the forms in which they are taken up by plants. A study was made on the following nuclides: /sup 22/Na, /sup 137/Cs, /sup 85/Sr, /Sup 54/Mn, /Sup 59/Fe, /Sup 60/ Co, /sup 65/Zn, /sup 124/Sb, /sup 141 in the cultivated soils permit the evaluation of the risks of contmination of the food chain and of the underground water. This study also showed new perspectives of the behavior of radionuclides as a function of their contmination of the organo-mineral wastes of industrial and domestic origin. This pollution interfers largely with the formation of stble complexes carried by the river to irrigated soils. The quality of the water determines the distribution of the radionuclides in the profile. The hydrosoluble complex persists in the soil and migrates toward the underground water level if they are not biodegradable. The stability of these forms as a function of the soil pH and of its physicochemical characteristics, as well as that of the radionuclides considered, permit the formulation of a new balance of the radionuclides in soils. The formulation of new proposals for the contml of nuclear sites is discussed. (tr-auth)

    1987-01-01

    In the report EUR 10118 '' Qualification, training, licensing and retraining of operating shift personnel in nuclear power plants'' the current practice in the countries of the European Communities as well as the procedures and programmes applied in Sweden, Switzerland and the USA are outlined and evaluated. The intent was to derive fundamental and generally valid concepts concerning shift-staff training and other relevant aspects. Those items were identified that seemed to be noteworthy because they give some guidance on how to achieve and maintain the qualification of the shift staff of NPPs or how to improve the staffing of the control room. These noteworthy topics identified by evaluation of the practice in countries of the European Communities and also elsewhere are presented in the publication at hand. The report addresses the following topics: tasks of the shift personnel, nomenclature for different grades of the personnel; shift staffing and staffing of the control room; criteria for personnel selection when recruiting new shift staff; personnel qualification necessary for recruitment; training of shift personnel; retraining and preservation of qualification standards; training facilities, especially simulators; responsibility for training; licensing/authorization; retirement from shift work. Consideration of these more general aspects and concepts may lead to improvement in training. The job descriptions given in the Annex to the document are only intended to give a general understanding of the typical designations, tasks and responsibilities of shift staff

  17. The role of LDCs in conservation and demand management in 2007 : the Ontario Clean Air Alliance's response to the Ontario Power Authority's options paper

    International Nuclear Information System (INIS)

    Gibbons, J.

    2006-01-01

    A response to The Ontario Power Authority (OPA) discussion paper on the role of local distribution companies (LDC) was presented, with reference to conservation and demand management (CDM). This paper examined 2 implicit issues raised by the OPA paper: (1) the appropriate role of the OPA with respect to conservation and demand management, and (2) the role of the Ontario Energy Board (OEB) in streamlining its CDM regulatory approval process. It was suggested that LDCs are ideal agencies for the delivery of CDM as they are trusted sources of energy information and have existing business relationships with electricity consumers. Local electric utilities understand local conditions and needs and are better placed to meet them. Ontario's electric utilities are now eligible for conservation profit bonuses equal to 5 per cent of the bill savings that their energy efficiency programs create for customers. It was noted that the benefits of CDM programs have already been demonstrated. The establishment of CDM budget targets was advised. Options to finance CDM programs were reviewed, as well as various energy efficiency programs. It was suggested that the OPA should continue to be a strong public advocate for CDM, and promote stricter provincial and federal energy efficiency standards. Recommendations for streamlining the OEB's CDM regulatory approval process were presented. It was concluded that marginalizing the role of Ontario's electric utilities in the delivery of CDM programs will short-circuit Ontario's efforts to develop a conservation culture. 13 refs

    2012-01-01

    This document presents the French national action plan defined by the Nuclear Safety Authority (ASN) in compliance with the recommendations made by the ENSREG (European nuclear safety regulators group). It refers to decisions taken at the national level after the Fukushima accident, recommendations after European stress tests, and recommendations after the extraordinary meeting of contracting parties at the Convention on Nuclear Safety of August 2012. For different topics, this document recalls the recommendations made by the peer review, indicates the ASN's opinion and progress or ASN's requirements for different power stations. The first part addresses the recommendations made by peers and based on the European review. Topics concern natural hazards (effects, detection, inspections and controls related to earthquakes, margin assessment with respect to flooding and natural hazards), the loss of safety systems (cooling systems, electricity supplies, actions, instruments, training, and so on), the management of a severe accident (reference levels, measures, guides, exercises, training, management of contaminated water, radiation protection, premises). The second part deals with topics addressed within the frame of the Convention: national organisations, organisations in an emergency and post-accidental situation, international cooperation. A third part addresses the follow-up of additional measures issued by the ASN

    1993-01-01

    Tucurui was the first big hydroelectric built in the Brazilian Amazonia (river Tocantins, Para). About 2400 Km 2 of Tropical Rain Forest was inundated. This work attempts to describe some effects of the Tucurui dam upon fish communities of the lower Tocantins river. Surveys of fish communities on the Tocantins were carried out by INPA, before and after the impoudment. Fishes belonging to 223 species was sampled by gillnets. After the impoudment, the average of species richness of the communities was reduced in 42% and 50%, respectively downstream and upstream the dam. In the reservoir, where rapids were flooded, species specialized in this habitats virtually disappeared during and after the filling up phase. The relative contribution of the illiophagous, that dominated the samples before the dam closure, downed, while there has been a sudden widespread of fish predators species in the reservoir. These predators dominated until the third year after the impoudment. The cluster analysis provide evidences that, between the species that take advantages of the impoundment, exist a clear succession of dominance. Until the end of sampling period all the study-area remained very instable, so is difficult to foresee the future composition or structure of the communities in the area under influence of Tucurui's Hydroelectric Dam.

  1. Integral ordering of the River Vardar Valley

    2004-01-01

    From Skopje to Gevgelia, an annual quantity of 4,5 billions M 3 of water flows out of the territory through the Vardar River for only 60 hours. This poses two questions. The first is whether the flowing out of the water can be decelerated, i.e., whether the water can be kept for at least 60 days and the second question is how this can be realized. Construction of 12 hydroelectric power plants is envisaged along Vardar River, i.e., its section extending from Skopje to the border on Greece, which means within a length of 200 km. Two of these are classical hydroelectric power plants (HPP 'Veles' and HPP 'Gradec'), while the remaining 10 hydroelectric power plants are distributed in a cascade along the river course, with small water head of H = 8,20 - 8,50 m and are considered ecological hydroelectric power plants according to European criteria. For us, these represent a new technology of design and construction particularly considering the part referring to the equipment, while in Europe, there is assembly-line production of such equipment. Presented very briefly in the paper shall be the main technical information on these hydroelectric power plants, namely HPP Kukuricani, as a pilot project to be realized by AD ESM. (Author)

  2. Mercury and other trace elements in Ohio River fish collected near coal-fired power plants: Interspecific patterns and consideration of consumption risks.

    2015-07-01

    Many coal-fired electric generating facilities in the United States are discharging higher loads of Hg, Se, and other chemicals to receiving streams due to the installation of flue gas desulfurization (FGD) air pollution control units. There are regulatory concerns about the potential increased uptake of these bioaccumulative trace elements into food webs. We evaluated the concentrations of As, total Hg (THg), methylmercury (MeHg), and Se in Ohio River fish collected proximal to coal-fired power plants, of which 75% operate FGD systems. Fillet samples (n = 50) from 6 fish species representing 3 trophic levels were analyzed. Geometric mean fillet concentrations of THg (wet wt), MeHg (wet wt), and Se (dry wt) in 3 species were 0.136, 0.1181, and 3.19 mg/kg (sauger); 0.123, 0.1013, and 1.56 mg/kg (channel catfish); and 0.127, 0.0914, and 3.30 mg/kg (hybrid striped bass). For all species analyzed, only 3 fillet samples (6% of total) had MeHg concentrations that exceeded the US Environmental Protection Agency (USEPA) human health criterion (0.3 mg/kg wet wt); all of these were freshwater drum aged ≥ 19 y. None of the samples analyzed exceeded the USEPA proposed muscle and whole body Se thresholds for protection against reproductive effects in freshwater fish. All but 8 fillet samples had a total As concentration less than 1.0 mg/kg dry wt. Mean Se health benefit values (HBVSe ) for all species were ≥ 4, indicating that potential Hg-related health risks associated with consumption of Ohio River fish are likely to be offset by adequate Se concentrations. Overall, we observed no measurable evidence of enhanced trace element bioaccumulation associated with proximity to power plant FGD facilities, however, some enhanced bioaccumulation could have occurred in the wastewater mixing zones. Furthermore, available evidence indicates that, due to hydraulic and physical factors, the main stem Ohio River appears to have low net Hg methylation potential. © 2015 SETAC.

    2005-01-01

    WAPDA being an esteemed organization of the country is involved in development of Water and Power Sector Projects. Ghazi Barotha Hydropower Project is another huge hydropower generation project in the country after Tarbela. The barrage to feed power channel of Ghazi Barotha Power Station are built over River Indus 7 Km down of Tarbela Dam. The project has been constructed to utilize the hydraulic head for power generation that is available between the tailrace of Tarbela Dam and the confluence of Haro River. In this reach river Indus drops by 76 m in distance of 63 Km. This is solely a power generation project with an installed capacity of 1450 MW. The purpose of this paper is to assess the negative impacts on the River Indus due to the construction of GBHP as Water of river Indus will be diverted to the power channel and the river Indus flows go to its lowest in low flow season. The reduction in river flow may change the ecology of the river - belas and people dependant on river water. In this context a study was made to keep the negative environmental impacts as low as possible and suggest mitigation measures to reduce negative impacts and provide enhancement measure to compensate the losses to be sustained by the area people and maintain the social life along with the ecology of the area less disturbed. The study demonstrated that the project is technically sound, economically viable and has limited environmental and social impacts on the area overall and specific the belas and people dependant on the Indus Water from Tarbela downstream up to confluence of Kabul River.

  5. Design and simulation of a control system for a run-off-river power plant; Entwurf und Simulation einer Staustufenregelung

    Ott, C.

    2000-07-01

    In run-off-river plants with low discharge and under head-control, changes of inflow lead to amplified changes of outflow. In this thesis a frequency-domain-based design-procedure is introduced, which allows to add an inflow-dependent signal to the head-controller of conventional combined head- and flow-controllers. This efficiently minimizes the discharge amplification. The non-linearity of the channel-reach is taken into consideration by adapting the settings of the controller to the actual discharge. The development of a time-domain-based program system, taking into account all nonlinearities of a run-off-river-plant, is described. Using different test-functions, the capability of the improved combined head- and flow-control can be demonstrated. In both the time- and the frequency-domain it is shown, that the quality of control is not influenced to a significant extent by the inevitable inaccuracies in the description of the channel-reach and in the measurement of the actual inflow and outflow.

    1988-01-01

    The purpose of this paper is to provide a author capability of current author indexing practices in journal literature indexing practices in 'Journal of Nuclear Science and Technology of Japan'. This Journal employed keywords freely assigned by author and not taken from INIS Thesaurus or other vocabulary list. Author examined 413 literatures, comparing keywords assigned by the literatures' authors with descriptor's (ATOMINDEX) assigned by an experienced professional indexer. The results of the comparisons showed that the average set of terms assigned by author included about 70% of all the terms assigned to the same literature by the professional indexer. Authors eventually would contribute, for the most effective point to create reference to information is at the time of its generation. Consequently, it may be possible to transfer them easily to descriptors in every secondary information system. (author)

    This study aimed to cluster and to quantify the wild-caught fingerlings nearby thermal power plant. Samples were monthly collected by bongo nets from four upstream sites of the Na Thap tidal river in Thailand from 2008 to 2013. Each caught species was identified, counted and calculated density in term of individuals per 1,000 cubic meters. A total of 45 aquatic animal fingerlings was commonly trapped in the average density of 2,652 individuals per 1,000 cubic meters of water volume (1,235–4,570). The results of factor analysis revealed that factor 1 was represented by the largest group of freshwater fish species, factors 2 represented a medium-sized group of mesohaline species, factor 3 represented several brackish species and factor 4 was a few euryhaline species. All four factor reached maximum levels during May to October. Total average numbers of fish fingerling caught at the outflow showed greater than those of other sampling sites. The impact of heated pollution from power plant effluents did not clearly detected. Overall water quality according the Thailand Surface Water Quality Standards Coastal tidal periodic and seasonal runoff phenomena exhibit influentially factors. Continuous ecological monitoring is strongly recommended.

  15. Environmental parameters of the Tennessee River in Alabama. 2: Physical, chemical, and biological parameters. [biological and chemical effects of thermal pollution from nuclear power plants on water quality

    1976-01-01

    Physical, chemical and biological water quality data from five sites in the Tennessee River, two in Guntersville Reservoir and three in Wheeler Reservoir were correlated with climatological data for three annual cycles. Two of the annual cycles are for the years prior to the Browns Ferry Nuclear Power Plant operations and one is for the first 14 months of Plant operations. A comparison of the results of the annual cycles indicates that two distinct physical conditions in the reservoirs occur, one during the warm months when the reservoirs are at capacity and one during the colder winter months when the reservoirs have been drawn-down for water storage during the rainy months and for weed control. The wide variations of physical and chemical parameters to which the biological organisms are subjected on an annual basis control the biological organisms and their population levels. A comparison of the parameters of the site below the Power plant indicates that the heated effluent from the plant operating with two of the three reactors has not had any effect on the organisms at this site. Recommendations given include the development of prediction mathematical models (statistical analysis) for the physical and chemical parameters under specific climatological conditions which affect biological organisms. Tabulated data of chemical analysis of water and organism populations studied is given.

    The protection of the aquatic and terrestrial environment from a wide range of radioactive contaminants released by nuclear industry requires continuous monitoring of radionuclides released into the environment. Specific measurement methods depending of the radionuclide are used to determinate this contribution. A lot of radionuclide can easily be measured at low level by gamma spectrometry, like {sup 137}Cs, {sup 60}Co..., but others like {sup 90}Sr, {sup 63}Ni or {sup 55}Fe require prior specific radiochemical separations. Activity of {sup 90}Sr values in environmental samples are available but only few measurements of {sup 63}Ni and {sup 55}Fe activities have been carried out in samples collected in the environment close to French nuclear power plants located on the Loire and Garonne rivers despite they represent 12% to 24% for {sup 63}Ni activity and <1% for {sup 55}Fe + other minor radionuclides of total activity of their liquid effluent discharges. {sup 90}Sr is not rejected by the liquid effluent discharges of Nuclear Power Plants and can be found in the environmental samples because of thermonuclear test and subsequently after the Chernobyl nuclear power plant accident. Considering the French Nuclear Power Plant located on Loire and Garonne rivers, the determination of {sup 90}Sr, {sup 63}Ni and {sup 55}Fe levels in the environmental samples around French nuclear power plants is carried out to detect the traces of these radionuclides originating from nuclear technology activities. The environment around five French nuclear Power Plants was investigated for 4 years between 2009 and 2014. The radionuclide activities determined by liquid scintillation counting after chemical steps were performed on a large set of various matrix samples likely to be encountered in environmental monitoring as soils, sediments, terrestrial and aquatic bio-indicators. It was found that the mean activity concentration of the most frequently detected was for the radionuclide {sup 90

  12. Novel Control Strategy for Multiple Run-of-the-River Hydro Power Plants to Provide Grid Ancillary Services

    Hydropower plant (HPP) generation comprises a considerable portion of bulk electricity generation and is delivered with a low-carbon footprint. In fact, HPP electricity generation provides the largest share from renewable energy resources, which include wind and solar. Increasing penetration levels of wind and solar lead to a lower inertia on the electric grid, which poses stability challenges. In recent years, breakthroughs in energy storage technologies have demonstrated the economic and technical feasibility of extensive deployments of renewable energy resources on electric grids. If integrated with scalable, multi-time-step energy storage so that the total output can be controlled, multiple run-of-the-river (ROR) HPPs can be deployed. Although the size of a single energy storage system is much smaller than that of a typical reservoir, the ratings of storages and multiple ROR HPPs approximately equal the rating of a large, conventional HPP. This paper proposes cohesively managing multiple sets of energy storage systems distributed in different locations. This paper also describes the challenges associated with ROR HPP system architecture and operation.

  13. The impacts of wind power integration on sub-daily variation in river flows downstream of hydroelectric dams.

    Due to their operational flexibility, hydroelectric dams are ideal candidates to compensate for the intermittency and unpredictability of wind energy production. However, more coordinated use of wind and hydropower resources may exacerbate the impacts dams have on downstream environmental flows, that is, the timing and magnitude of water flows needed to sustain river ecosystems. In this paper, we examine the effects of increased (i.e., 5%, 15%, and 25%) wind market penetration on prices for electricity and reserves, and assess the potential for altered price dynamics to disrupt reservoir release schedules at a hydroelectric dam and cause more variable and unpredictable hourly flow patterns (measured in terms of the Richards-Baker Flashiness (RBF) index). Results show that the greatest potential for wind energy to impact downstream flows occurs at high (∼25%) wind market penetration, when the dam sells more reserves in order to exploit spikes in real-time electricity prices caused by negative wind forecast errors. Nonetheless, compared to the initial impacts of dam construction (and the dam's subsequent operation as a peaking resource under baseline conditions) the marginal effects of any increased wind market penetration on downstream flows are found to be relatively minor.

    2003-12-01

    This document provides a comprehensive review of Bonneville Power Administration (BPA) funded activities within the Hood River Basin from 1991 to 2001. These activities, known as the Hood River Production Program (HRPP), are intended to mitigate for fish losses related to operation of federal dams in the Columbia River Basin, and to contribute to recovery of endangered and/or threatened salmon and steelhead, as directed by Nation Oceanic and Atmospheric Administration - Fisheries (NOAA Fisheries). The Environmental Impact Statement (EIS) for the HRPP, which authorized BPA to fund salmon and steelhead enhancement activities in the Hood River Basin, was completed in 1996 (BPA 1996). The EIS specified seven years of monitoring and evaluation (1996-2002) after program implementation to determine if program actions needed modification to meet program objectives. The EIS also called for a program review after 2002, that review is reported here.

  16. Authoring Tools

    Authoring tools that are accessible and that enable authors to produce accessible Web content play a critical role in web accessibility. Widespread use of authoring tools that comply to the W3C Authoring Tool Accessibility Guidelines (ATAG) would ensure that even authors who are neither knowledgeable about nor particularly motivated to produce accessible content do so by default. The principles and techniques of ATAG are discussed. Some examples of accessible authoring tools are described including authoring tool content management components such as TinyMCE. Considerations for creating an accessible collaborative environment are also covered. As part of providing accessible content, the debate between system-based personal optimization and one universally accessible site configuration is presented. The issues and potential solutions to address the accessibility crisis presented by the advent of rich internet applications are outlined. This challenge must be met to ensure that a large segment of the population is able to participate in the move toward the web as a two-way communication mechanism.

  17. Renewal of the small hydro power plant 'La Foulaz' on the river Orbe in Vallorbe, Switzerland; Rehabilitation de la petite centrale hydroelectrique de la Foulaz sur l'Orbe a Vallorbe. Etude d'avant projet - Rapport final

    For now nearly four centuries, hydro power is used on the site named 'La Foulaz' on the river Orbe in the Vallorbe municipal territory. The existing small-scale hydro power plant is under neglect since 1970, although it enjoys a permanent water usage concession of 4.2 m{sup 3}/s. Since June 2008 the company 'La Foulaz Energie SA' owns the site and the water concession and is planning the renewal of the hydro power plant. The plan is to replace the existing permanent water flow rate usage concession by a higher water flow rate usage one of reasonable but limited duration. Reliable hydrological data are available from the Swiss Federal Administration as well as from the electricity utility 'Romande Energie SA' that operates the 'La Dernier' hydro power plant located up-stream. According to these data the design flow rate of 10 m{sup 3}/s has been selected for the new 'La Foulaz' plant. The available water head for the turbine is in the range 1.46 to 3-00 m, depending on the flow rate in the river Orbe. The average annual power production is estimated to 708,000 kWh. The peak electrical power would be 164 kW. With a cost recovery time of 25 years the production cost is estimated to 25 Swiss cents/kWh. This just enables to balance the budget. (author)

    2014-10-01

    With the development of economy, the health of river ecosystem is severely threatened because of the increasing effects of human activities on river ecosystem. In this paper, the authors assessed the river ecosystem health in aspects of chemical integrity and biological integrity, using the criterion in water quality, nutrient, and benthic macroinvertebrates of 73 samples in Haihe River Basin. The research showed that the health condition of river ecosystem in Haihe River Basin was bad overall since the health situation of 72. 6% of the samples was "extremely bad". At the same time, the health situation in Haihe River Basin exhibited obvious regional gathering effect. We also found that the river water quality was closely related to human activities, and the eutrophication trend of water body was evident in Haihe River Basin. The biodiversity of the benthic animal was low and lack of clean species in the basin. The indicators such as ammonia nitrogen, total nitrogen and total phosphorus were the key factors that affected the river ecosystem health in Haihe River Basin, so the government should start to curb the deterioration of river ecosystem health by controlling these nutrients indicators. For river ecosystem health assessment, the multi-factors comprehensive evaluation method was superior to single-factor method.

  14. Croatian-Hungarian cooperation on the Danube river radioactivity measurements

    International Nuclear Information System (INIS)

    Lulic, S.; Vancsura, P.

    2003-01-01

    Danube river radioactivity measurements on the border profile Mohac-Batina have been performed since the beginning of 1978 with varying frequency of sampling. Thus, in the period before nuclear power plant Paks started to work joint croatian-hungarian sampling at the border profile was taking place four times a year; the obtained results of measured radioactivity levels were used to assess radioactivity background data. From the start of nuclear power plant Paks running until Chernobyl reactor accident (April 1986) sampling was performed six times a year. After the Chernobyl accident, samples have been taken every month. Since decreased Chernobyl reactor accident influence was estimated until present samples have been taken six times a year. On the Danube river border profile the concentration activity of gamma radionuclides has been determined in water samples (filtered water and suspended matter), and in fish, sediment and Danube river algae samples.

  12. Novel Control Strategy for Multiple Run-of-the-River Hydro Power Plants to Provide Grid Ancillary Services

    Energy Technology Data Exchange (ETDEWEB)

    Electricity generated by Hydropower Plants (HPPs) contributes a considerable portion of bulk electricity generation and delivers it with a low carbon footprint. In fact, HPP electricity generation provides the largest share from renewable energy resources, which includes solar and wind energy. The increasing penetration of wind and solar penetration leads to a lowered inertia in the grid and hence poses stability challenges. In recent years, breakthrough in energy storage technologies have demonstrated the economic and technical feasibility of extensive deployments in power grids. Multiple ROR HPPs if integrated with scalable, multi time-step energy storage so that the total output can be controlled. Although, the size of a single energy storage is far smaller than that of a typical reservoir, cohesively managing multiple sets of energy storage distributed in different locations is proposed. The ratings of storages and multiple ROR HPPs approximately equals the rating of a large, conventional HPP. The challenges associated with the system architecture and operation are described. Energy storage technologies such as supercapacitors, flywheels, batteries etc. can function as a dispatchable synthetic reservoir with a scalable size of energy storage will be integrated. Supercapacitors, flywheels, and battery are chosen to provide fast, medium, and slow responses to support grid requirements. Various dynamic and transient power grid conditions are simulated and performances of integrated ROR HPPs with energy storage is provided. The end goal of this research is to investigate the inertial equivalence of a large, conventional HPP with a unique set of multiple ROR HPPs and optimally rated energy storage systems.

    Full Text Available In this article, the authors suggest that one method for increasing awareness of the benefits of data sharing can be affected by administering a survey, hopefully encouraging either a minority or majority influence on other members of the behavioural science community. The authors describe the process for creating such a survey and provide their survey, although untested. This is a well-timed article as the existing literature on social and behavioural science data is quite thin. The majority/minority influence of norms is a nice theoretical construct to explore. This is definitely one approach to increase awareness of the benefits of data sharing.

  14. Dating sediment cores from Hudson River marshes

    International Nuclear Information System (INIS)

    Robideau, R.; Bopp, R.F.

    1993-01-01

    There are several methods for determining sediment accumulation rates in the Hudson River estuary. One involves the analysis of the concentration of certain radionuclides in sediment core sections. Radionuclides occur in the Hudson River as a result of: natural sources, fallout from nuclear weapons testing and low level aqueous releases from the Indian Point Nuclear Power Facility. The following radionuclides have been studied in the authors work: Cesium-137, which is derived from global fallout that started in the 1950's and has peaked in 1963. Beryllium-7, a natural radionuclide with a 53 day half-life and found associated with very recently deposited sediments. Another useful natural radionuclide is Lead-210 derived from the decay of Radon-222 in the atmosphere. Lead-210 has a half-life of 22 years and can be used to date sediments up to about 100 years old. In the Hudson River, Cobalt-60 is a marker for Indian Point Nuclear Reactor discharges. The author's research involved taking sediment core samples from four sites in the Hudson River Estuarine Research Reserve areas. These core samples were sectioned, dried, ground and analyzed for the presence of radionuclides by the method of gamma-ray spectroscopy. The strength of each current pulse is proportional to the energy level of the gamma ray absorbed. Since different radionuclides produce gamma rays of different energies, several radionuclides can be analyzed simultaneously in each of the samples. The data obtained from this research will be compared to earlier work to obtain a complete chronology of sediment deposition in these Reserve areas of the river. Core samples may then by analyzed for the presence of PCB's, heavy metals and other pollutants such as pesticides to construct a pollution history of the river
