    Because primary energies such as fossil fuels, nuclear energy and renewable energy are limited in quantity of supply, it is necessary to use available energies effectively for the increase of energy demand that is inevitable this century while keeping environment in good condition. For this purpose, an efficient synergistic energy conversion process using nuclear energy and fossil fuels together converted to energy carriers such are electricity, hydrogen, and synthetic fuels seems to be effective. Synergistic energy conversion processes containing nuclear energy were surveyed and effects of these processes on resource saving and the CO 2 emission reduction were discussed. (T.T.)

    The energy loss effect in nuclear matter, which is a nuclear effect apart from the nuclear effect on the parton distribution as in deep-inelastic scattering process, can be measured best by the nuclear dependence of the high energy nuclear Drell-Yan process. By means of the nuclear parton distribution studied only with lepton deep-inelastic scattering experimental data, the measured Drell-Yan production cross sections for 800 GeV proton incident on a variety of nuclear targets are analyzed within the Glauber framework which takes into account the energy loss of the beam proton. It is shown that the theoretical results with considering the energy loss effect are in good agreement with the FNAL E866 data. (orig.)

  3. Nuclear energy and process heating

    Nuclear energy generated in fission reactors is a versatile commodity that can, in principle, satisfy any and all of mankind's energy needs through direct or indirect means. In addition to its dominant current use for electricity generation and, to a lesser degree, marine propulsion, nuclear energy can and has been used for process heat applications, such as space heating, industrial process heating and seawater desalination. Moreover, a wide variety of reactor designs has been employed to this end in a range of countries. From this spectrum of experience, two design approaches emerge for nuclear process heating (NPH): extracting a portion of the thermal energy from a nuclear power plant (NPP) (i.e., creating a combined heat and power, or CHP, plant) and transporting it to the user, or deploying dedicated nuclear heating plants (NHPs) in generally closer proximity to the thermal load. While the former approach is the basis for much of the current NPH experience, considerable recent interest exists for the latter, typically involving small, innovative reactor plants with enhanced and passive safety features. The high emphasis on inherent nuclear safety characteristics in these reactor designs reflects the need to avoid any requirement for evacuation of the public in the event of an accident, and the desire for sustained operation and investment protection at minimum cost. Since roughly 67% of mankind's primary energy usage is not in the form of electricity, a vast potential market for NPH systems exists, particularly at the low-to-moderate end-use temperatures required for residential space heating and several industrial applications. Although only About 0.5% of global nuclear energy production is presently used for NPH applications, an expanded role in the 21st century seems inevitable, in part, as a measure to reduce greenhouse gas emissions and improve air quality. While the technical aspects of many NPH applications are considered to be well proven, a

    1 - Description of program or function: NMTC/JAM is an upgraded version of the code system NMTC/JAERI97. NMTC/JAERI97 simulates high energy nuclear reactions and nucleon-meson transport processes. It implements an intra-nuclear cascade model taking account of the in-medium nuclear effects and the pre-equilibrium calculation model based on the exciton one. For treating the nucleon transport process, the nucleon-nucleus cross sections are revised to those derived by the systematics of Pearlstein. Moreover, the level density parameter derived by Ignatyuk is included as a new option for particle evaporation calculation. A geometry package based on the Combinatorial Geometry with multi-array system and the importance sampling technique is implemented in the code. Tally function is also employed for obtaining such physical quantities as neutron energy spectra, heat deposition and nuclide yield without editing a history file. The code can simulate both the primary spallation reaction and the secondary particle transport in the intermediate energy region from 20 MeV to 3.5 GeV by the use of the Monte Carlo technique. The code has been employed in combination with the neutron-photon transport codes available to the energy region below 20 MeV for neutronics calculation of accelerator-based subcritical reactors, analyses of thick target spallation experimented and so on. 2 - Methods: High energy nuclear reactions induced by incident high energy protons, neutrons and pions are simulated with the Monte Carlo Method by the intra-nuclear nucleon-nucleon reaction probabilities based on an intra-nuclear nucleon cascade model followed by the particle evaporation including high energy fission process. Jet-Aa Microscopic transport model (JAM) is employed to simulate high energy nuclear reactions in the energy range of GeV. All reaction channels are taken into account in the JAM calculation.

    The energy loss effect in nuclear matter is another nuclear effect apart from the nuclear effects on the parton distribution as in deep inelastic scattering process. The quark energy loss can be measured best by the nuclear dependence of the high energy nuclear Drell-Yan process. By means of three kinds of quark energy loss parameterizations given in literature and the nuclear parton distribution extracted only with lepton-nucleus deep inelastic scattering experimental data, measured Drell-Yan production cross sections are analyzed for 800 GeV proton incident on a variety of nuclear targets from FNAL E866. It is shown that our results with considering the energy loss effect are much different from those of the FNAL E866, who analyzes the experimental data with the nuclear parton distribution functions obtained by using the deep inelastic IA collisions and pA nuclear Drell-Yan data. Considering the existence of energy loss effect in Drell-Yan lepton pairs production, we suggest that the extraction of nuclear parton distribution functions should not include Drell-Yan experimental data.

    The industrialized nations require 75% of the energy as heat and it is likely that developing countries in the course of industrialization will show a comparable energy consumption structure. The High Temperature Reactor (HTR) allows the utilization of nuclear energy at high temperatures as process heat. In the Federal Republic of Germany (FRG) the development in the relevant technical areas is well advanced and warrants investigation as a matter for transfer to Brazil. In Brazil nuclear process heat finds possible applications in steel making, shale oil extraction, petroleum refining, and in the more distant future coal gasification with distribution networks. Based on growth forecasts for these industries a theoretical potential market of 38-53 GW (th) can be identified. At present nuclear process heat is marginally more expensive than conventional fossil technologies but the anticipated development is expected to add an economic incentive to the emerging necessity of providing a sound energy base in the developing countries.

    Use of energy in a sustainable manner is to make processes more efficient. Oil industry requires of electricity and steam for refinery and petrochemical processes, nuclear energy can be a clean energy alternative. Cogeneration is an option to be assessed by Mexico to provide additional value to electricity generation. Mexico is a country with oil resources that requires process heat for gasoline production among other things. With the concern about the climate change and sustain ability policies it is adequate to use cogeneration as a way to optimize energy resources. Currently there is a national program that considers cogeneration for several Mexican refineries, and the first choices are combined cycle plants and thermo power plants using residual oil. This is long term program. The pebble bed modular reactor (PBMR) is a next generation reactors that works with very high temperatures that can be used to produce steam process along with electricity, in this work two different couplings are assessed for the PBMR reactor to produce steam process, the two couplings are compared for using in the Mexican refineries and some conclusions are given.

    Nuclear reactors are potential sources for generating process heat, and their applications for such use economically competitive. They help satisfy national needs by helping conserve and extend oil and natural gas resources, thus reducing energy imports and easing future international energy concerns. Several reactor types can be utilized for generating nuclear process heat; those considered here are light water reactors (LWRs), heavy water reactors (HWRs), gas-cooled reactors (GCRs), and liquid metal reactors (LMRs). LWRs and HWRs can generate process heat up to 280 0 C, LMRs up to 540 0 C, and GCRs up to 950 0 C. Based on the studies considered here, the estimated process heat markets and the associated energy markets which would be supplied by the various reactor types are summarized

    Today we know two forms of nuclear energy: fission and fusion. Fission is the decomposition of heavy nuclei, while fusion is the melting together of light nuclei. Both processes create a large surplus of energy. Technologically, we can currently only use fission to produce energy in today's nuclear power plants, but there is intense research worldwide in order to realize a controlled fusion process. In a practical context, today's nuclear energy is a sustained source of energy since the resource base is virtually unlimited. When fusion technology is realized, the resource supply will be a marginal problem. (AG)

    A concept to produce hydrogen of an energy carrier using nuclear energy was proposed since 1970s, and a number of process based on thermochemical method has been investigated after petroleum shock. As this method is used high temperature based on nuclear reactors, these researches are mainly carried out as a part of application of high temperature reactors, which has been carried out at an aim of the high temperature reactor application in the Japan Atomic Energy Research Institute. On October, 2000, the 'First International Conference for Information Exchange on Hydrogen Production based on Nuclear Energy' was held by auspice of OECD/NEA, where hydrogen energy at energy view in the 21st Century, technology on hydrogen production using nuclear energy, and so on, were published. This commentary was summarized surveys and researches on hydrogen production using nuclear energy carried out by the Nuclear Hydrogen Research Group established on January, 2001 for one year. They contains, views on energy and hydrogen/nuclear energy, hydrogen production using nuclear energy and already finished researches, methods of hydrogen production using nuclear energy and their present conditions, concepts on production plants of nuclear hydrogen, resources on nuclear hydrogen production and effect on global environment, requests from market and acceptability of society, and its future process.

    It is anticipated that the coupled utilization of coal and nuclear energy will achieve great importance in the future, the coal serving mainly as raw material and nuclear energy more as primary energy. Prerequisite for this development is the availability of high-temperature reactors, the state of development of which is described here. Raw materials for coupled use with nuclear process heat are petroleum, natural gas, coal, lignite, and water. Steam reformers heated by nuclear process heat, which are suitable for numerous processes, are expected to find wide application. The article describes several individual methods, all based on the transport of gas in pipelines, which could be utilized for the long distance transport of 'nuclear energy'.

  18. Uranium mining, processing and nuclear energy - opportunities for Australia?

    International Nuclear Information System (INIS)

    2006-12-01

    On 6 June 2006, the Prime Minister announced the appointment of a taskforce to undertake an objective, scientific and comprehensive review of uranium mining, value-added processing and the contribution of nuclear energy in Australia in the longer term. This is known as the Review of Uranium Mining Processing and Nuclear Energy in Australia, referred to in this report as the Review. The Prime Minister asked the Review to report by the end of 2006. A draft report was released for public comment on 21 November 2006 and was also reviewed by an expert panel chaired by the Chief Scientist (see Appendix F). The Review is grateful for comments provided on the draft report by members of the public. The report has been modified in the light of those comments. In response to its initial call for public comment in August 2006 the Review received over 230 submissions from interested parties. It also conducted a wide range of consultations with organisations and individuals in Australia and overseas, and commissioned specialist studies on various aspects of the nuclear industry. Participating in the nuclear fuel cycle is a difficult issue for many Australians and can elicit strong views. This report is intended to provide a factual base and an analytical framework to encourage informed community discussion. Australia's demand for electricity will more than double before 2050. Over this period, more than two-thirds of existing electricity generation will need to be substantially upgraded or replaced and new capacity added. The additional capacity will need to be near-zero greenhouse gas emitting technology if Australia is just to keep greenhouse gas emissions at today's levels. Many countries confront similar circumstances and have therefore considered the use of nuclear power for some of the following reasons: the relative cost competitiveness of nuclear power versus the alternatives; security of supply and independence from fossil fuel energy imports; diversity of domestic

    2016-09-01

    In the present work, is theoretically proven that the residual heat, removed by the chillers in the stage prior to the compression of the recuperative Brayton cycle with which nuclear power plants operate with high temperature gas reactors (HTGR), can be used to produce stem and desalinate seawater. The desalination process selected for the analysis, based on its operating characteristics, is the Multi-Stage Distillation (Med). The Med process will use as energy source, for the flash evaporation process in the flash trap, the residual heat that the reactor coolant dissipates to the environment in order to increase the compression efficiency of the same; the energy dissipated depends on the operating conditions of the reactor. The Med distillation process requires saturated steam at low pressure which can be obtained by means of a heat exchanger, taking advantage of the residual heat, where the relative low temperatures with which the process operates make the nuclear plants with HTGR reactors ideal for desalination of sea water, because they do not require major modifications to their design of their operation. In this work the energy analysis of a six-stage Med module coupled to the chillers of an HTGR reactor of the Pebble Bed Modular Reactor type is presented. Mathematical modeling was obtained by differential equations of mass and energy balances in the system. The results of the analysis are presented in a table for each distillation stage, estimating the pure water obtained as a function of the heat supplied. (Author)

    When compared to other energy sources such as fossil fuels, coal, oil, and gas, nuclear energy has perhaps the lowest impact on the environment. Moreover, nuclear energy has also benefited other fields such as medicine, pharmaceutical industry, and agriculture, among others. However, despite all benefits that result from the peaceful uses of nuclear energy, the theme is still addressed with prejudice. Education may be the starting point for public acceptance of nuclear energy as it provides pedagogical approaches, learning environments, and human resources, which are essential conditions for effective learning. So far nuclear energy educational researches have been conducted using only conventional assessment methods. The global educational scenario has demonstrated absence of neuroscience-based methods for the teaching of nuclear energy, and that may be an opportunity for developing new strategic teaching methods that will help demystifying the theme consequently improving public acceptance of this type of energy. This work aims to present the first step of a methodology in progress based on researches in neuroscience to be applied to Brazilian science teachers in order to contribute to an effective teaching/learning process. This research will use the Implicit Association Test (IAT) to verify implicit attitudes of science teachers concerning nuclear energy. Results will provide data for the next steps of the research. The literature has not reported a similar neuroscience-based methodology applied to the nuclear energy learning/teaching process; therefore, this has demonstrated to be an innovating methodology. The development of the methodology is in progress and the results will be presented in future works. (author)

  3. The application of nuclear energy to the Canadian chemical process industry

    1976-03-01

    A study has been made to determine what role nuclear energy, either electrical or thermal, could play in the Canadian chemical process industry. The study was restricted to current-scale CANDU type power reactors. It is concluded that the scale of operation of the chemical industry is rarely large enough to use blocks of electrical power (e) of 500 MW or thermal power (t) of 1500 MW. Thus, with a few predictable exceptions, the role of nuclear energy in the Canadian chemical industry will be as a general thermal/electrical utility supplier, serving a variety of customers in a particular geographic area. This picture would change if nuclear steam generators of 20 to 50 MW(t) become available and are economically competitive. (author)

    An analysis is given of the consequences resulting from the Dutch government's decision to use both coal and uranium for electricity production. The energy yields are calculated for the total conversion processes, from the mine to the processing of waste and the demolition of the installations. The ecological aspects considered include the nature and quantity of the waste produced and its effect on the biosphere. The processing of waste is also considered here. Attention is given to the safety aspects of nuclear energy and the certainties and uncertainties attached to nuclear energy provision, including the value of risk-analyses. Employment opportunities, the economy, nuclear serfdom and other social aspects are discussed. The author concludes that both sources have grave disadvantages and that neither can become the energy carrier of the future. (C.F.)

    One of the IAEA's statutory objectives is to 'seek to accelerate and enlarge the contribution of atomic energy to peace, health and prosperity throughout the world.' One way this objective is achieved is through the publication of a range of technical series. Two of these are the IAEA Nuclear Energy Series and the IAEA Safety Standards Series. According to Article III.A.6 of the IAEA Statute, the safety standards establish 'standards of safety for protection of health and minimization of danger to life and property'. The safety standards include the Safety Fundamentals, Safety Requirements and Safety Guides. These standards are written primarily in a regulatory style, and are binding on the IAEA for its own programmes. The principal users are the regulatory bodies in Member States and other national authorities. The IAEA Nuclear Energy Series comprises reports designed to encourage and assist R and D on, and application of, nuclear energy for peaceful uses. This includes practical examples to be used by owners and operators of utilities in Member States, implementing organizations, academia, and government officials, among others. This information is presented in guides, reports on technology status and advances, and best practices for peaceful uses of nuclear energy based on inputs from international experts. The IAEA Nuclear Energy Series complements the IAEA Safety Standards Series. Nuclear generated hydrogen has important potential advantages over other sources that will be considered for a growing hydrogen share in a future world energy economy. Still, there are technical uncertainties in nuclear hydrogen processes that need to be addressed through a vigorous research and development effort. Safety issues as well as hydrogen storage and distribution are important areas of research to be undertaken to support a successful hydrogen economy in the future. The hydrogen economy is gaining higher visibility and stronger political support in several parts of the

    The technical and economic studies were performed to examine the possible installation of a small, integral pressurized water reactor as an industrial energy source in the Duval Corporation's Frasch Process sulfur mining operation located in Culberson County, Texas. Since this is the first industrial application study attempted for this type of reactor, it has been a learning process on the nuclear plant side as well as the industrial side, particularly in the area of economic analysis. The importance of considering inflationary effects, the significance of plant financing form, and the annualized, after-tax cash flow and incremental rate-of-return methods of comparison in determing energy costs have all been recognized during the course of the study

    Hoffmann, J.; Kuczera, B.

    2001-05-01

    The terms radioactivity and nuclear energy, which have become words causing irritation in the political sphere, actually represent nothing but a large potential for innovative exploitation of natural resources. The contributions to this publication of the Karlsruhe Research Center examine more closely three major aspects of radioactivity and nuclear energy. The first paper highlights steps in the history of the discovery of radioactivity in the natural environment and presents the state of the art in health physics and research into the effects of exposure of the population to natural or artificial radionuclides. Following contributions focus on: Radiochemical methods applied in the medical sciences (diagnostic methods and devices, therapy). Nuclear energy and electricity generation, and the related safety policies, are an important subject. In this context, the approaches and pathways taken in the field of nuclear science and technology are reported and discussed from the angle of nuclear safety science, and current trends are shown in the elaboration of advanced safety standards relating to nuclear power plant operation and ultimate disposal of radioactive wastes. Finally, beneficial aspects of nuclear energy in the context of a sustainable energy policy are emphasized. In particular, the credentials of nuclear energy in the process of building an energy economy based on a balanced energy mix which combines economic and ecologic advantages are shown. (orig./CB) [de

    2000-01-01

    Public perception on nuclear energy is much influenced by subjective impressions mostly formed through sensational and dramatic news of mass media or anti-nuclear groups. However, nuclear experts, those who have more relevant knowledge and information about nuclear energy, may have reasonable opinion based on scientific facts or inferences. Thus their opinion and consensus should be examined and taken into account during the process of nuclear energy policy formulation. For the purpose of eliciting experts' opinion, the web-based on-line survey system (eBOSS) was developed. Using the survey system, experts' views on nuclear energy were tallied, analyzed and compared with the public's. Based on the survey results, the paper suggests some recommendations about the future direction of the public information program in Korea

    Nuclear energy is faltering in many places - especially in the USA: should it be written off. The author sees underlying trends that justify a more optimistic view of nuclear energy's future - the continuing tendency for the electricity intensity of economic activity to rise while the total energy intensity falls; a consistently favourable price trend for electricity compared with energy prices generally - a trend that may become more favourable if his judgment that nuclear plants will turn out to be very long-lived is borne out by events; the substitution of electricity-based processes in industry for older processes; and the development of ultra-safe reactors which will remove once and for all the fears of accidents such as the one that occurred at Three Mile Island.

    The NRV (nuclear reactions video) is an open and permanently extended global system of management and graphical representation of nuclear data and video-graphic computer simulation of low energy nuclear dynamics. It consists of a complete and renewed nuclear database and well known theoretical models of low energy nuclear reactions altogether forming the 'low energy nuclear knowledge base'. The NRV solves two main problems: 1) fast and visualized obtaining and processing experimental data on nuclear structure and nuclear reactions; 2) possibility for any inexperienced user to analyze experimental data within reliable commonly used models of nuclear dynamics. The system is based on the realization of the following principal things: the net and code compatibility with the main existing nuclear databases; maximal simplicity in handling: extended menu, friendly graphical interface, hypertext description of the models, and so on; maximal visualization of input data, dynamics of studied processes and final results by means of real three-dimensional images, plots, tables and formulas and a three-dimensional animation. All the codes are composed as the real Windows applications and work under Windows 95/NT

    Nuclear energy is controversial. But what's all about really in the controversy? It's about more than safty or electricity prices. Nuclear energy is not only a technical or political question, but also a moral, a human. The discussion enter various rational and irrational arguments, beside straightforward arguments various misleading and mendacious exist. The present publication is comprehensively dedicated to the thema of nuclear energy - its pro and contra - and considers its risks and advantages. Thereby the sources of energy, the processes in the nuclear reactor, and the risk potentials (Harrisburg, Chernobyl, Fukushima) are illustratively and reproducibly presented. Extensively the text explains the forms of the radiation, its doses, and the tolerance of it. Also to the theme waste and final disposal an explaining chapter is dedicated and the question for the exit from nuclear energy elucidated. Finally the author appoints with the question ''How considers mankind nuclear energy world-wide'' the international comparison.

  5. Energy Balance of Nuclear Power Generation. Life Cycle Analyses of Nuclear Power

    2011-01-01

    The accident at the Japanese nuclear power plant Fukushima in March 2011 triggered a debate about phasing out nuclear energy and the safety of nuclear power plants. Several states are preparing to end nuclear power generation. At the same time the operational life time of many nuclear power plants is reaching its end. Governments and utilities now need to take a decision to replace old nuclear power plants or to use other energy sources. In particular the requirement of reducing greenhouse gas emissions (GHG) is used as an argument for a higher share of nuclear energy. To assess the contribution of nuclear power to climate protection, the complete life cycle needs to be taken into account. Some process steps are connected to high CO2 emissions due to the energy used. While the processes before and after conventional fossil-fuel power stations can contribute up to 25% of direct GHG emission, it is up to 90 % for nuclear power (Weisser 2007). This report aims to produce information about the energy balance of nuclear energy production during its life cycle. The following key issues were examined: How will the forecasted decreasing uranium ore grades influence energy intensity and greenhouse emissions and from which ore grade on will no energy be gained anymore? In which range can nuclear energy deliver excess energy and how high are greenhouse gas emissions? Which factors including ore grade have the strongest impact on excess energy? (author)

    1989-01-01

    In Switzerland as in other countries public opinion on nuclear energy has drastically changed with time. Surveys show that a majority at present favours abandoning nuclear energy in Switzerland, but does not consider feasible an immediate switchover to other forms of energy. The behaviour is contradictory because increasingly more electric power is used, even after Chernobyl. The resistence has many facets. The debate is largely focused on the question of future technological and economic development. Nuclear energy also became the scapegoat for a development of the last few decades it has not been responsible for (destruction of the environment, waste of natural resources). For the sake of the environment and future economic development, the continued use of nuclear energy has to be ensured. This calls for great efforts in order to convince the people that nuclear power is an essential and logical part of our energy supply. In this process, the fear of a nuclear energy and the unease about industrial society must not be dismissed as irrelevant. (orig.)

    2015-02-01

    The nuclear hybrid energy concept is becoming a reality for the US energy infrastructure where combinations of the various potential energy sources (nuclear, wind, solar, biomass, and so on) are integrated in a hybrid energy system. This paper focuses on challenges facing a hybrid system with a Small Modular Reactor at its core. The core of the paper will discuss efforts required to develop supervisory control center that collects data, supports decision-making, and serves as an information hub for supervisory control center. Such a center will also be a model for integrating future technologies and controls. In addition, advanced operations research, thermal cycle analysis, energy conversion analysis, control engineering, and human factors engineering will be part of the supervisory control center. Nuclear hybrid energy infrastructure would allow operators to optimize the cost of energy production by providing appropriate means of integrating different energy sources. The data needs to be stored, processed, analyzed, trended, and projected at right time to right operator to integrate different energy sources.

    In this paper, a comparison is made between the energy produced in a nuclear cycle in a light-water reactor without recycling of plutonium or uranium on the one hand and the energy stored into the system to realize this energy production on the other. Only empirical data are used, which means that some energy costs are omitted because no empirical data were available (e.g. energy needed to waste processing and waste disposal). The following steps are taken into account: production and processing of ores, conversion and enrichment of fuels, construction and shutdown of the reactor itself. (Auth.)

    Today, about 80 developing countries are using nuclear techniques in various sectors of their national economies. In the sector of industry, the radiation processing using gamma rays of high energy electrons has grown. While in the sector of health care, an estimated 10000 gamma cameras-imaging instruments are used in combination with radioisotopes in medical diagnosis. In the field of agriculture there is, nearly, 1000 crop varieties derived from radiaton-induced mutations which are grown worldwide. Furthermore and concerning the energy sector there is 417 nuclear power plants operating in 26 countries, accounting for just 16% of the world's total electricity production; the nuclear energy helped in developing and supporting a variety of sciences. 2 tabs

    1982-01-01

    This book originated in the training courses for teachers of grammar- and secondary schools in Dillingen (Bavaria). The aim of these courses is to become informed about the latest state in one field of physics. The lectures are well-known experts in the respective fields. In the latest study (1980) of the National Academy of Sciences the experts came to the conclusion that without further development nuclear power plants the utilization of too much coal would become necessary and involve irreversible environmental damage (see chapter 6). There are two important obstacles impeding the further extension of nuclear energy. The first problem to be solved is the processing and storage of radioactive waste. This is a more technical task and can be treated in a satisfactory way. The second obstacle is less easy to take as the population has to be convinced that a nuclear power plant can be operated with almost unbelievable safety (see chapter 5) and be shut down safely in the case of incidents. The most promising possibility of controlled nuclear fusion as energy source is still many decades- if feasible at all- away from being performed (see chapter. 7). In the Soviet Union 25% of the electric energy production shall be proceed from nuclear power plants by the year 1990. (orig./GL) [de

    The importance of oil sand as a primary energy carrier is illustrated. The oil sand mining project 'synfuel' in Fort McMurray, Alberta, Canada, is described. On the basis of a layout of an In-situ-process different possibilities of introducing nuclear energy to the process are described. This leads to an increase of the product yield, leading finally to a doubling of the energy output compared to the reference layout. The introduction of nuclear energy contributes to the reduction of emissions, in particular to the emission of carbon dioxide in the conversion process. (orig.)

    Do Georgia needs nuclear energy? Nuclear energy is high technology and application of such technology needs definite level of industry, science and society development. Nuclear energy is not only source of electricity production - application of nuclear energy increases year-by-year for medical, science and industrial use. As an energy source Georgia has priority to extend hydro-power capacity by reasonable use of all available water resources. In parallel regime the application of energy efficiency and energy conservation measures should be considered but currently this is not prioritized by Government. Meanwhile this should be taken into consideration that attempts to reduce energy consumption by increasing energy efficiency would simply raise demand for energy in the economy as a whole. The Nuclear energy application needs routine calculation and investigation. For this reason Government Commission is already established. But it seems in advance that regional nuclear power plant for South-Caucasus region would be much more attractive for future

    Energy release process in nuclear reactions induced by fast hadrons in hadron-nucleus collisions is discussed. Some portion of the internal nuclear energy is released when the locally damaged in a collision, and instable therefore, residual target nucleus transits itself into light nuclear fragments (nucleons, D, T) and a stable lighter final nucleus or some number of stable lighter nuclei. It is not excluded that in some of the collisions the induced intranuclear nuclear reactions may be energy overcompensating. Corresponding reconnaissance should be made - in analysing the nuclear reactions induced in hadron-nucleus collisions

    1995-01-01

    International nuclear trade is governed by the regime of legal control of nuclear energy, nuclear materials, knowledge of nuclear processes and weapons. Nuclear trade is under pinned by international agreements concerning physical protection and safeguards, the control of nuclear weapons, the protection of nuclear materials from terrorist action and third part liability. The political and geographical boundary changes of the past two years have significantly altered the background against which this regime has developed. Such changes have affected nuclear trade. The paper summarised the legal control of nuclear energy between States, identifies the areas of change which may affect this regime and the consequences for international trade. Conclusions are drawn as to the development of the international legal control of nuclear energy. (author). 21 refs

    This report presents facts and figures on new nuclear energy in the Netherlands, in the period after 2020. The information is meant to support a stakeholder discussion process on the role of new nuclear power in the transition to a sustainable energy supply for the Netherlands. The report covers a number of issues relevant to the subject. Facts and figures on the following issues are presented: Nuclear power and the power market (including impact of nuclear power on electricity market prices); Economic aspects (including costs of nuclear power and external costs and benefits, impact on end user electricity prices); The role of nuclear power with respect to security of supply; Sustainability aspects, including environmental aspects; The impact of nuclear power in three 'nuclear energy scenarios' for the Netherlands, within the context of a Northwest European energy market. The scenarios are: (1a) No new nuclear power in the Netherlands ('Base case'); (1b) After closure of the existing Borssele nuclear power plant by the end of 2033, the construction of new nuclear power plant that will operate in 2040. That plant is assumed to be designed not to have a serious core melt down accident (e.g. PBMR) (200 to 500 MWe); (2) New nuclear power shortly after closure the Borssele nuclear power plant in 2033 (1000 to 1600 MWe, 3rd Generation); (3) New nuclear power plants shortly after 2020 (2000 to 5000 MWe, 3rd Generation). Two electricity demand scenario background scenario variants have been constructed based on an average GDP growth of about 2% per year up to 2040. The first variant is based on a steadily growing electricity demand and on currently established NL and EU policies and instruments. It is expected to be largely consistent with a new and forthcoming reference projection 'Energy and Emissions 2010-2020' for the Netherlands (published by ECN and PBL in 2010). A lower demand variant is based on additional energy savings and on higher shares of renewable

    1981-01-01

    At the end of 1980 nuclear energy accounted for 9% of the world production of electricity stemming from 262 power stations, utilising mainly the process of water reactors and representing an installed capacity of 142 GWe. This production, apparently limited, already represents the equivalent of 150 million TOE. The 600 nuclear power stations in service, under construction or ordered represent a total of 450 GWe. In 1985, their production ought to cover 15% of the world requirements of electricity, which corresponds to a doubling of the share of nuclear energy within 6 years. During these recent years, the development of nuclear energy has undergone a significant slowing down and the number of orders for new nuclear power stations has dropped considerably in particular in the United States. Considering the time required and the available industrial capacity, the accumulated capacity which could be installed worlwide by 1990 could attain 530 GWe, equivalent to 650 MTOE covering 24% of the world production of electricity and 7% of the world consumption of primary energy. A determined effort for the end of this century could end up by the installation of 1200 GWe of capacity, generating 1.5 GTOE. The share of nuclear energy would then represent 35% of the production of electricity [fr

    The subject of the study is the analysis of trends, the level and the determinants of the attitude to nuclear energy on the basis of survey data from representative samples. The emphasis is on analyzing the attitude to nuclear energy in the context of the so-called new political line of conflict. The most striking result of the trend analysis of the attitude to four energy systems - nuclear energy, coal, mineral oil, natural gas - was the drastic decline in the acceptance of nuclear energy in the time period covered by the available time series. The trends observed lead one to suppose that the evaluation of energy systems is no simple numbers game of the kind that means a more negative assessment of one energy system unavoidably leads to a more positive assessment of the other and vice versa, but that the individual energy systems are judged at least in part independently of one another. Effective public relations information and events may play an important part in changing attitudes to the individual energy systems. Structural factors are primarily a change in political values and an increased political competence on the part of the citizens. Both these factors taken together have created a greater perception of and sensitivity to the side-effects of the technical-industrial growth process. This aspect of the side-effects has been politicized by the New Social Movements particularly with reference to nuclear energy. Provided that political lines of conflict are important and lasting mechanisms for structuring, then nuclear energy will probably remain a constant theme, because of its importance in symbolizing fundamental problems at the technical-industrial growth process.

    In the present work, is theoretically proven that the residual heat, removed by the chillers in the stage prior to the compression of the recuperative Brayton cycle with which nuclear power plants operate with high temperature gas reactors (HTGR), can be used to produce stem and desalinate seawater. The desalination process selected for the analysis, based on its operating characteristics, is the Multi-Stage Distillation (Med). The Med process will use as energy source, for the flash evaporation process in the flash trap, the residual heat that the reactor coolant dissipates to the environment in order to increase the compression efficiency of the same; the energy dissipated depends on the operating conditions of the reactor. The Med distillation process requires saturated steam at low pressure which can be obtained by means of a heat exchanger, taking advantage of the residual heat, where the relative low temperatures with which the process operates make the nuclear plants with HTGR reactors ideal for desalination of sea water, because they do not require major modifications to their design of their operation. In this work the energy analysis of a six-stage Med module coupled to the chillers of an HTGR reactor of the Pebble Bed Modular Reactor type is presented. Mathematical modeling was obtained by differential equations of mass and energy balances in the system. The results of the analysis are presented in a table for each distillation stage, estimating the pure water obtained as a function of the heat supplied. (Author)

    Do we need nuclear energy. Is it safe. What are the risks. Will it lead to proliferation. The questions are endless, the answers often confused. In the vigorous debates that surround the siting and operation of nuclear power plants, it is all too easy to lose sight of the central issues amid the mass of arguments and counter-arguments put forward. And there remains the doubt, who do we believe. This book presents the facts, simply, straightforwardly, and comprehensibly. It describes the different types of nuclear reactor, how they work, how energy is produced and transformed into usable power, how nuclear waste is handled, what safeguards are built in to prevent accident, contamination and misuse. More important, it does this in the context of the real world, examining the benefits as well as the dangers of a nuclear power programme, quantifying the risks, and providing an authoritative account of the nuclear industry worldwide. Technically complex and politically controversial, the contribution of nuclear energy to our future energy requirements is a crucial topic of our time. (author)

    It is well known that nuclear energy generation does not produce greenhouse gases emissions which are responsible of the climate change on a global scale. Nevertheless nuclear energy suffers a kind of stagnation due to a disproportionate perception of risk by the public. In this paper, reference is made to a technology aimed to the use of nuclear reactors to eliminate the high level wastes by means of the spallation process with the combined use of a proton accelerator and a nuclear reactor. Some results are presented confirming that feedback with nuclear waste and thorium instead of uranium reduces drastically the potential danger of nuclear waste

    A comprehensive analysis and comparison of different energy resources available to human usage. The first in the row is the fossil energy, obtained by burning hydrocarbons and its effects, i.e. acid rains and global warming. A second example is that of renewable sources, like hydro energy and its effects like the problems generated by the necessary dams. Other renewables are wind energy, used on a small scale yet, basically clean, however with damaging effects like noise, and solar energy. Nuclear energy has its own risks, generated mainly by nuclear accidents. However, the mainly open cycle fuel consumption has the problem of creating radioactive nuclear waste. Safety in nuclear power plants is based on negative feed-back, the principles of single failure, diversity and depth protection, including the importance of human factor. The breakdown on April 10, 2003 at Paks PWP NPP is also analysed. It has been caused by residual heat during a maintenance process in an already stopped reactor, lacking proper cooling. (Gy.M.)

    We all want to prevent the use of nuclear weapons. The issue before us is how best to achieve this objective; more specifically, whether the peaceful applications of nuclear energy help or hinder, and to what extent. Many of us in the nuclear industry are working on these applications from a conviction that without peaceful nuclear energy the risk of nuclear war would be appreciably greater. Others, however, hold the opposite view. In discussing the subject, a necessary step in allaying fears is understanding some facts, and indeed facing up to some unpalatable facts. When the facts are assessed, and a balance struck, the conclusion is that peaceful nuclear energy is much more part of the solution to preventing nuclear war than it is part of the problem

    Europe is one of the world leaders in nuclear technology advancement. The development of spent fuel reprocessing is but one example of this. This process continues today with the development by France and Germany of the European Pressurised-Water Reactor. Nuclear research and development work is continuing in Europe, and must be continued in the future, if Europe is to retain its world leadership position in the technological field and on the commercial front. If we look at the benefits, which nuclear energy has to offer, in economic and environmental terms, 1 support the view that nuclear is an energy source whose time has come again. This is not some fanciful notion or wishful thinking. There is clear evidence of greater long-term reliance on nuclear energy. Perhaps we do not see new nuclear plants springing up in Europe, but we do see ambitious nuclear power development programmes underway in places like China, Japan and Korea. Closer to home, Finland is seriously considering the construction of a new nuclear unit. Elsewhere, in Europe and the US, we see a growing trend towards nuclear plant life extension and plant upgrades geared towards higher production capacity. These are all signs that nuclear will be around for a long time to come and that nuclear will indeed have a future

    Nuclear data processing for reactor physics calculation has been done. Raw nuclear data cross-sections on file ENDF should be prepared and processed before it used in neutronic calculation. The processing code system such as NJOY-PC code has been used from linearization of nuclear cross-sections data and background contribution of resonance parameter (MF2) using RECONR module (0K) with energy range from 10 -5 to 10 7 eV. Afterward, the neutron cross-sections data should be processed and broadened to desire temperature (i.e. 293K) by using BROADR module. The Grouper and Therma modules will be applied for multi-groups calculation which suitable for WIMS/D4 (69 groups) and thermalization of nuclear constants. The final stage of processing nuclear cross-sections is updating WIMS/D4 library. The WIMSR module in NJOY-PC and WILLIE code will be applied in this stage. The evaluated nuclear data file, especially for 1 H 1 isotope, was taken from JENDL-3.2 and ENDF/B-VI for preliminary study. The results of nuclear data processing 1 H 1 shows that the old-WIMS (WIMS-lama) library have much discrepancies comparing with JENDL-3.2 or ENDF/B-VI files, especially in energy around 5 keV

    The future of nuclear energy is widely discussed with emphasis on the compatibility with social structure. Projected growth of nuclear power generation, demands for nuclear fuel resources and services, and comparison of power generation costs with other energy sources are presented and discussed based on the published data. As one of the processing problems in fuel cycle industry, the problem of reprocessing plant is discussed mainly from the view point of managing radioactive wastes including trans-actinides. Here the importance of establishing regulating standards is emphasized. A logical decision process for regulating large scale nuclear power development is proposed and explained and it is concluded that the largest obstacle for large scale development is the lack of decisions about regulation. In other words, the problem is not of technological feature but of software. Other problems discussed in this paper include, the multipurpose utilization of nuclear energy with the combination of LWR, FBR, and HTR, plutonium physical protection, the problem of energy park, and multi-national energy center. Finally, a historical review is given of the relations between the scale of energy utilization and the social structure and technological innovations. It is deduced that a new social pattern will be required for the large scale utilization of nuclear energy. (Aoki, K.)

    Energy is the power of the world's economies, whose appetite for this commodity is increasing as the leading economies expand and developing economies grow. How to provide the energy demanded while protecting our environment and conserving natural resources is a vital question facing us today. Many parts of our society are debating how to power the future and whether nuclear energy should play a role. Nuclear energy is a complex technology with serious issues and a controversial past. Yet it also has the potential to provide considerable benefits. In pondering the future of this imposing technology, people want to know. - How safe is nuclear energy? - Is nuclear energy economically competitive? - What role can nuclear energy play in meeting greenhouse gas reduction targets? - What can be done with the radioactive waste it generates? - Does its use increase the risk of proliferation of nuclear weapons? - Are there sufficient and secure resources to permit its prolonged exploitation? - Can tomorrow's nuclear energy be better than today's? This publication provides authoritative and factual replies to these questions.

    Energy analysis is a systematic way of tracing and accounting for the flows of energy through an industrial system and apportioning a quantity of the primary energy input to each of the goods and services sent out. The application of energy accounting to nuclear power stations and their growth in generating systems is discussed. Misunderstandings arising from discrepancies and weaknesses in some published simple analyses of hypothetical growth situations are outlined. Results of a more complex energy flow analysis are used to demonstrate that current nuclear energy programs are running at an energy profit. Large fossil fuel savings will occur in a real electrical grid system under anticipated nuclear power growth rates. These savings will give a new dimension in planning the use of fossil energy resources which will still be needed for transport and industrial processes, such as steelmaking, for some time to come.

    We study the bulk deformation properties of the Skyrme nuclear energy density functionals. Following simple arguments based on the leptodermous expansion and liquid drop model, we apply the nuclear density functional theory to assess the role of the surface symmetry energy in nuclei. To this end, we validate the commonly used functional parametrizations against the data on excitation energies of superdeformed band-heads in Hg and Pb isotopes, and fission isomers in actinide nuclei. After subtracting shell effects, the results of our self-consistent calculations are consistent with macroscopic arguments and indicate that experimental data on strongly deformed configurations in neutron-rich nuclei are essential for optimizing future nuclear energy density functionals. The resulting survey provides a useful benchmark for further theoretical improvements. Unlike in nuclei close to the stability valley, whose macroscopic deformability hangs on the balance of surface and Coulomb terms, the deformability of neutron-rich nuclei strongly depends on the surface-symmetry energy; hence, its proper determination is crucial for the stability of deformed phases of the neutron-rich matter and description of fission rates for r-process nucleosynthesis.

    This nuclear energy roadmap has been prepared jointly by the IEA and the OECD Nuclear Energy Agency (NEA). Unlike most other low-carbon energy sources, nuclear energy is a mature technology that has been in use for more than 50 years. The latest designs for nuclear power plants build on this experience to offer enhanced safety and performance, and are ready for wider deployment over the next few years. Several countries are reactivating dormant nuclear programmes, while others are considering nuclear for the first time. China in particular is already embarking on a rapid nuclear expansion. In the longer term, there is great potential for new developments in nuclear energy technology to enhance nuclear's role in a sustainable energy future.

    The new energy approach towards nuclear, due to the growing political support at the beginning of this century, is the result of a complexity of economical, social, political and technological factors. The history of peaceful use of nuclear energy in Romania goes back 45 years. Considering the strategic importance of the energy sector in developing the national economy on sustainable basis, the sector evolution should be outlined through prognosis and strategies on different horizons of time, so that the development perspectives and the energy supply to be correctly estimated. This necessity is emphasized in the Governmental Program of the present administration, which takes into consideration Romanian Economic Strategy on medium term and also The Government Action Plan on 2000-2004, agreed with the European Commission. In order to implement the Governmental Program, the Ministry of Industries and Resources elaborates the National Energy Strategy. The Government Action Plan draw up the conclusion that Unit 2 from Cernavoda NPP must be finalized. This solution fits the least-cost energy development planning and answers to environment requirements. Romania became a Member State of the Agency in 1957. From the mid-1960s to the mid-1970s its technical co-operation program with the Agency covered mainly research in nuclear physics and some medical and other applications of radiation and isotopes. Since 1976, when the Romanian nuclear power program was embarking to use CANDU-type reactors, the Agency has supported mainly the activities related to the Cernavoda NPP. In the framework of the Romanian accession process to the European structures, CNCAN co-operates with European Commission for transposition of the communautaire acquis in the field of nuclear activities. Romania has had laws in place governing the regulation of nuclear activities since 1974. They were remained in force throughout and subsequent to the national constitutional changes started in 1989 until 1996

    With this report the German Federal Diet submits the final results of the opinion-forming and decision-making process concerning the recommendations made by the investigation committee 'Future Nuclear Energy Policy' in June 1980. By means of this report it is intended to point out to an interested public the difficult and time-consuming process of parliamentary decision-making. This report is also to be seen as the final opinion delivered on the recommendations made by the investigation committee. The recommendations were to continue to pursue the peaceful use of nuclear energy, the necessity and technical justifiability of which had basically been approved by all parliamentary groups. In view of the import of the subject and in recognition of the work done by the investigation committee, the German Parliament has thoroughly discussed the report and has reviewed the analyses and recommendations in conjunction with other political fields to be considered. One part of the recommendations was taken up almost unanimously. As far as the safety of nuclear installations is concerned, the investigation committee could not submit any new findings which would give reasons for modifying the hitherto positive assessment of the safety of nuclear installations. The recommendations of the investigation committee mainly referred to the decision-making process in the field of energy policy which will effect the next decade. What fundamental decisions are to be made until when was pointed out as well as the findings and experience to be made until then. (orig./HP) [de

    2006-01-01

    In the early 1970s, Patrick Moore, a co-founder of Greenpeace, believed that nuclear energy was synonymous with nuclear holocaust. Thirty years on, his views have changed because nuclear energy is the only non-greenhouse-gas-emitting power source that can effectively replace fossil fuels while satisfying the world's increasing demand for energy. Today, 441 nuclear plants operating globally avoid the release of nearly 3 billion tonnes of CO 2 emissions annually-the equivalent of the exhaust from more than 428 million cars. Concerns associated with nuclear energy are discussed including costs of nuclear energy, safety of nuclear plants, radioactive waste management, vulnerability of nuclear plants to terrorist attacks and diversion of nuclear fuel for weaponization. It is concluded that nuclear energy is the best way to produce safe, clean, reliable baseload electricity, and will play a key role in achieving global energy security. With climate change at the top of the international agenda, we must all do our part to encourage a nuclear energy renaissance

    Nuclear energy is back on the agenda worldwide. In order to prepare for the next decades and to set priorities in nuclear R and D and investment, market share scenarios are evaluated. This allows to identify the triggers which influence the market penetration of future nuclear reactor technologies. To this purpose, scenarios for a future nuclear reactor park in Europe have been analysed applying an integrated dynamic process modelling technique. Various market share scenarios for nuclear energy are derived including sub-variants with regard to the intra-nuclear options taken, e.g. introduction date of Gen-III (i.e. EPR) and Gen-IV (i.e. SCWR, HTR, FR) reactors, level of reprocessing, and so forth. The assessment was undertaken using the DANESS code which allows to provide a complete picture of mass-flow and economics of the various nuclear energy system scenarios. The analyses show that the future European nuclear park will exist of combinations of Gen-III and Gen-IV reactors. This mix will always consist of a set of reactor types each having its specific strengths. Furthermore, the analyses highlight the triggers influencing the choice between different nuclear energy deployment scenarios. In addition, a dynamic assessment is made with regard to manpower requirements for the construction of a future nuclear fleet in the different scenarios. (authors)

  2. Kaon condensates, nuclear symmetry energy and cooling of neutron stars

    The cooling of neutron stars by URCA processes in the kaon-condensed neutron star matter for various forms of nuclear symmetry energy is investigated. The kaon-nucleon interactions are described by a chiral Lagrangian. Nuclear matter energy is parametrized in terms of the isoscalar contribution and the nuclear symmetry energy in the isovector sector. High density behaviour of nuclear symmetry energy plays an essential role in determining the composition of the kaon-condensed neutron star matter which in turn affects the cooling properties. We find that the symmetry energy which decreases at higher densities makes the kaon-condensed neutron star matter fully protonized. This effect inhibits strongly direct URCA processes resulting in slower cooling of neutron stars as only kaon-induced URCA cycles are present. In contrast, for increasing symmetry energy direct URCA processes are allowed in the almost whole density range where the kaon condensation exists.

    1990-01-01

    This set of questions is based on an inquiry from the years 1987 to 1989. About 250 people af all age groups - primarily, however, young people between 16 and 25 years of age - were asked to state the questions they considered particularly important on the subject of nuclear energy. The survey was carried out without handicaps according to the brain-storming principle. Although the results cannot claim to be representative, they certainly reflect the areas of interest of many citizens and also their expectations, hopes and fears in connection with nuclear energy. The greater part of the questions were aimed at three topic areas: The security of nuclear power-stations, the effects of radioactivity on people and the problem of waste disposal. The book centres around these sets of questions. The introduction gives a general survey of the significance of nuclear energy as a whole. After this follow questions to do with the function of nuclear power stations, for the problems of security and waste disposal - which are dealt with in the following chapters - are easier to explain and to understand if a few physical and technical basics are understood. In the final section of the book there are questions on the so-called rejection debate and on the possibility of replacing nuclear energy with other energy forms. (orig./HP) [de

    1993-11-01

    The present Dutch government compiled the title document to enable the future Dutch government to declare its opinion on the nuclear energy problemacy. The most important questions which occupy the Dutch society are discussed: safe application and risks of nuclear energy, radioactive wastes and other environmental aspects, and the possible danger of misusing nuclear technology. In chapter two attention is paid to the policy, as formulated by the Dutch government, with regard to risks of nuclear power plants. Next the technical safety regulations that have to be met are dealt with. A brief overview is given of the state of the art of commercially available nuclear reactors, as well as reactors under development. The nuclear waste problem is the subject of chapter three. Attention is paid to the Dutch policy that has been formulated and is executed, the OPLA-program, in which the underground storage of radioactive wastes is studied, the research on the conversion of long-lived radioactive isotopes to short-lived radioactive isotopes, and planned research programs. In chapter four, other environmental effects of the use of nuclear power are taken into consideration, focusing on the nuclear fuel cycle. International obligations and agreements to guarantee the peaceful use of nuclear energy (non-proliferation) are mentioned and discussed in chapter four. In chapter six the necessity to carry out surveys to determine public support for the use of nuclear energy is outlined. In the appendices nuclear energy reports in the period 1986-present are listed. Also the subject of uranium supplies is discussed and a brief overview of the use of nuclear energy in several other countries is given. 2 tabs., 5 annexes, 63 refs

    The Nuclear Energy Institute (NEI) provided a brief presentation on the state of energy demand in the United States and discussed the improving economics for new nuclear power plants. He discussed the consolidation of companies under deregulation and the ability of these larger companies to undertake large capital projects such as nuclear power plant construction. He discussed efforts under way to support a new generation of plants but noted that there needs to be greater certainty in the licensing process. He discussed infrastructure challenges in terms of people, hardware, and services to support new and current plants. He stated that there needs to be fair and equitable licensing fees and decommissioning funding assurance for innovative modular designs such as the PBMR. He concluded that NRC challenges will include resolving 10 CFR Part 52 implementation issues, establishing an efficient and predictable process for siting, COL permits and inspection, and an increasing regulatory workload

    1993-02-01

    Our choice of energy sources has important consequences for the economy and the environment. Nuclear energy is a controversial energy source, subject to much public debate. Most individuals find it difficult to decide between conflicting claims and allegations in a variety of technical subjects. Under these circumstances, knowledge of various relevant inquiries can be helpful. This publication summarizes the composition and major findings of more than thirty nuclear energy inquiries. Most of the these are Canadian, but others are included where they have relevance. The survey shows that, contrary to some claims, virtually every aspect of nuclear energy has been subject to detailed scrutiny. The inquiries' reports include many recommendations on how nuclear energy can be exploited safely, but none rejects it as an acceptable energy source when needed. (Author) 38 refs

    Full Text Available Sustainable energy development implies the need for the emerging potential energy sources which are not producing adverse effect to the environment. In this respect nuclear energy has gained the complimentary favor to be considered as the potential energy source without degradation of the environment. The sustainability evaluation of the nuclear energy systems has required the special attention to the criteria for the assessment of nuclear energy system before we can make firm justification of the sustainability of nuclear energy systems. In order to demonstrate the sustainability assessment of nuclear energy system this exercise has been devoted to the potential options of nuclear energy development, namely: short term option, medium term option, long term option and classical thermal system option. Criteria with following indicators are introduced in this analysis: nuclear indicator, economic indicator, environment indicator, social indicator... The Sustainability Index is used as the merit for the priority assessment among options under consideration.

  9. Net energy from nuclear power

    1975-11-01

    An analysis of net energy from nuclear power plants is dependent on a large number of variables and assumptions. The energy requirements as they relate to reactor type, concentration of uranium in the ore, enrichment tails assays, and possible recycle of uranium and plutonium were examined. Specifically, four reactor types were considered: pressurized water reactor, boiling water reactor, high temperature gas-cooled reactor, and heavy water reactor (CANDU). The energy requirements of systems employing both conventional (current) ores with uranium concentration of 0.176 percent and Chattanooga Shales with uranium concentration of 0.006 percent were determined. Data were given for no recycle, uranium recycle only, and uranium plus plutonium recycle. Starting with the energy requirements in the mining process and continuing through fuel reprocessing and waste storage, an evaluation of both electrical energy requirements and thermal energy requirements of each process was made. All of the energy, direct and indirect, required by the processing of uranium in order to produce electrical power was obtained by adding the quantities for the individual processes. The energy inputs required for the operation of a nuclear power system for an assumed life of approximately 30 years are tabulated for nine example cases. The input requirements were based on the production of 197,100,000 MWH(e), i.e., the operation of a 1000 MW(e) plant for 30 years with an average plant factor of 0.75. Both electrical requirements and thermal energy requirements are tabulated, and it should be emphasized that both quantities are needed. It was found that the electricity generated far exceeded the energy input requirements for all the cases considered

  10. Geopolitical and Economic Aspects of Nuclear Energy

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Nuclear power in its present form was created during the Cold War and is its heritage. The main objective of nuclear energy at that time, along with energy, was the creation and accumulation of nuclear materials. To this aim a existing nuclear power plants based on uranium-plutonium cycle. Everything else - the processing of radioactive waste and spent nuclear fuel, storage, recycling themselves nuclear power plant after its end of life, the risks of proliferation of nuclear materials and other environmental issues - minor. It was also believed that the nuclear power plant - the most reliable and safe plant. During the last twenty years all over the world the number of new orders for nuclear aggregates has decreased. That happens for a number of reasons, including public resistance, that the construction of new NPP and the excess of energy utilities in many markets, which is mainly connected with high market competition in energy markets and low economic indicators of the current nuclear utilities. The technology that consists of low capital costs, a possibility for quick construction and guarantied exploitation quality is on the winners side, but currently this technology is absent. However, despite abovementioned downsides, as the experience of state corporation "Rosatom"has shown, many developing countries of the South-east Asia, The middle East, African regions express high interest in the development of nuclear energy in their countries. The decision whether to develop nuclear energy or to continue to develop is, in the end, up to the choice of the tasks that a country faces. The article describes these "minor" issues, as well as geopolitical and economic problems of the further development of nuclear energy.

    The current concern with diminishing supplies of non-renewable energy has brought into clearer focus the debate on the future of nuclear energy. Application of the risk assessment process to the biological effects of radiation is considered worthwhile so that the nature and order of the hazards entailed can be appreciated in the total context of the problem. The derivation of regulations and the process of cost-risk-benefit analysis are also discussed. In view of the widespread public concern and, on occasion, apprehension about the development of nuclear energy it has been thought useful to tabulate the elements of this concern so as to gain a fuller understanding of the manner in which the public perceives and weighs risks.

    The problem of the utilization of nuclear energy is not only technical but also has important social, economic, political and ethical ramifications. Therefore, to discuss nuclear energy for the future, a vision of the new era needs to be identified. A model for the new era, as a natural consequence of growing interdependence among nations and the process of human evolution is described. The problems of inherent and passive safety, waste disposal, ecology, proliferation, economy and regulatory institutions in the new era are discussed. The particular role of small nuclear power reactors and their potential advantages are described. (author). 12 refs

    1984-01-01

    The goal of Four Modernizations in China requires doubling present energy production by the year 2000. Because of uneven geographic distribution of coal and hydropower resources, difficulties in exploitation and transportation, and environmental issues, conventional energy alone could not meet the tremendous energy demand in the most densely populated and highly industrialized coastal provinces. Therefore nuclear energy will play an increasingly important role in such regions and is now considered indispensable for the development of China's economy. Nuclear energy will supply not only base-load electricity but district heating and process heat in these provinces. Another promising potential application of nuclear heat will be in the petroleum industry. Nuclear energy will find broad applications in various sectors of China's economy as the country achieves the Four Modernizations. (author)

  3. Is nuclear energy ethically justifiable?

    International Nuclear Information System (INIS)

    Zuend, H.

    1987-01-01

    Nuclear technology offers the chance to make an extremely long term contribution to the energy supply of the earth. The use of nuclear energy is ethically justifiable, provided that several fundamental rules are obeyed during the technical design of nuclear installations. Such fundamental rules were unequivocally violated in the nuclear power plant Chernobyl. They are, however, fulfilled in the existing Swiss nuclear power plants. Improvements are possible in new nuclear power plants. Compared to other usable energy systems nuclear energy is second only to natural gas in minimal risk per generated energy unit. The question of ethical justification also may rightly be asked of the non-use of nuclear energy. The socially weakest members of the Swiss population would suffer most under a renunciation of nuclear energy. Future prospects for the developing countries would deteriorate considerably with a renunciation by industrial nations of nuclear energy. The widely spread fear concerning the nuclear energy in the population is a consequence of non-objective discussion. 8 refs., 2 figs

    Lithium is a material of great interest in the world, it is found in different minerals on Earth's crust (spodumene, lepidolite, amblygonite and petalite) also in salt pans. This element belongs to alkaline group and has two natural isotopes: Li-6 and Li-7. In the nuclear field, lithium isotopes are used for different purposes. The Li-6 is applied in the production of energy, because its section of shock is larger than the other isotope. The Li-7 regulates the pH in refrigerant material in the primary circuits of the Pressurized Water Nuclear Reactor (PWR). In nuclear reactor, lithium is used as a heat transfer due its boiling temperature (1342°C), making it an excellent thermal conductor. However, to reach all these applications, lithium must have high purity (> 99%). The main processes to reach a high purity level of lithium employee a combination of solvent extraction and ion exchange process, to obtain its salts or ending with chemical electrolysis of its chlorides to obtain its pure metal. This work presents a review of new applications of Lithium in Nuclear Energy and its purification and enrichment processes. (author)

    Carlos Villota. Director of Nuclear Energy of UNESA gave an overview of the Spanish nuclear industry, the utility companies and the relevant institutions. Companies of the nuclear industry include firms that produce heavy components or equipment (ENSA), manufacturers of nuclear fuel (ENUSA), engineering companies, the National Company for Radioactive Waste Management (ENRESA), and nuclear power plants (nine units at seven sites). Nuclear energy is a significant component of the energy mix in Spain: 11% of all energy produced in Spain is of nuclear origin, whilst the share of nuclear energy in the total electricity generation is approximately 23%. The five main players of the energy sector that provide for the vast majority of electricity production, distribution, and supply have formed the Spanish Electricity Industry Association (UNESA). The latter carries out co-ordination, representation, management and promotion tasks for its members, as well as the protection of their business and professional interests. In the nuclear field, UNESA through its Nuclear Energy Committee co-ordinates aspects related to nuclear safety and radiological protection, regulation, NPP operation and R and D. Regarding the institutional framework of the nuclear industry, ENSA, ENUSA and ENRESA are controlled by the national government through the Ministry of Economy and Finance and the Ministry of Science and Technology. All companies of the nuclear industry are licensed by the Ministry of Industry, Tourism and Trade (MITYC), while the regulatory body is the Nuclear Safety Council (CSN). It is noteworthy that CSN is independent of the government, as it reports directly to Parliament. (author)

  12. Nuclear Hybrid Energy Systems: Imperatives, Prospects, and Challenges

    International Nuclear Information System (INIS)

    Aumeier, Steven E.

    2010-01-01

    As global population reaches an expected 8 billion people by 2030, primary energy consumption is expected to increase by almost 40% from approximately 520 exajoules consumed today to almost 740 exajoules. Much of this increase is expected to come from non-Organization for Economic Cooperation and Development (OECD) nations, and Asia specifically. In these economies, energy used for transportation is expected to grow substantially, as is industrial, commercial and to a lesser degree residential energy use, creating considerable pressure on global and local energy markets. The magnitude and timing of growth in energy consumption likely will create a global imperative to deploy energy production technologies that balance the three pillars of energy security: (1) economic stability - related to the affordability of energy products, stability and predictability in their price, and the efficient and effective deployment of global capital resources in their development; (2) environmental sustainability - related to minimizing the negative impacts of energy production to air, land, and water systems and advancing the long-term viability of using a particular resource in a way that does not limit future generations ability to prosper; (3) resource security - related to the ability to access energy resources and products where and when necessary, in an affordable and predictable manner. One approach to meeting these objectives is hybrid energy systems (HES). Broadly described, HES are energy product production plants that take two or more energy resource inputs (typically includes both carbon and non-carbon based sources) and produce two or more energy products (e.g. electricity, liquid transportation fuels, industrial chemicals) in an integrated plant. Nuclear energy integration into HES offers intriguing potential, particularly if smaller (<300 MWe) reactors are available. Although the concept of using nuclear energy in a variety of non-electrical process applications is

One way it achieves this objective is to issue publications in various series. Two of these series are the IAEA Nuclear Energy Series and the IAEA Safety Standards Series. According to Article III, paragraph A.6, of the IAEA Statute, the IAEA safety standards establish 'standards of safety for protection of health and minimization of danger to life and property.' The safety standards include the Safety Fundamentals, Safety Requirements and Safety Guides. These standards are primarily written in a regulatory style, and are binding on the IAEA for its own activities. The principal users are Member State regulatory bodies and other national authorities. The IAEA Nuclear Energy Series consists of reports designed to encourage and assist research on, and development and practical application of, nuclear energy for peaceful uses. This includes practical examples to be used by owners and operators of utilities in Member States, implementing organizations, academia and politicians, among others. The information is presented in guides, reports on the status of technology and advances, and best practices for peaceful uses of nuclear energy based on inputs from international experts. The series complements the IAEA's safety standards, and provides detailed guidance, experience, good practices and examples on the five areas covered in the IAEA Nuclear Energy Series. The Nuclear Energy Basic Principles is the highest level publication in the IAEA Nuclear Energy Series and describes the rationale and vision for the peaceful uses of nuclear energy. It presents eight Basic Principles on which nuclear energy systems should be based to fulfil nuclear energy's potential to help meet growing global energy needs. The Nuclear Energy Series Objectives are the second level publications. They describe what needs to be

  16. Nuclear energy for hydrogen production

    2007-01-01

    In the long term, H 2 production technologies will be strongly focusing on CO 2 -neutral or CO 2 -free methods. Nuclear with its virtually no air-borne pollutants emissions appears to be an ideal option for large-scale centralized H 2 production. It will be driven by major factors such as production rates of fossil fuels, political decisions on greenhouse gas emissions, energy security and independence of foreign oil uncertainties, or the economics of large-scale hydrogen production and transmission. A nuclear reactor operated in the heat and power cogeneration mode must be located in close vicinity to the consumer's site, i.e., it must have a convincing safety concept of the combined nuclear/ chemical production plant. A near-term option of nuclear hydrogen production which is readily available is conventional low temperature electrolysis using cheap off-peak electricity from present nuclear power plants. This, however, is available only if the share of nuclear in power production is large. But as fossil fuel prices will increase, the use of nuclear outside base-load becomes more attractive. Nuclear steam reforming is another important near-term option for both the industrial and the transportation sector, since principal technologies were developed, with a saving potential of some 35 % of methane feedstock. Competitiveness will benefit from increasing cost level of natural gas. The HTGR heated steam reforming process which was simulated in pilot plants both in Germany and Japan, appears to be feasible for industrial application around 2015. A CO 2 emission free option is high temperature electrolysis which reduces the electricity needs up to about 30 % and could make use of high temperature heat and steam from an HTGR. With respect to thermochemical water splitting cycles, the processes which are receiving presently most attention are the sulfur-iodine, the Westinghouse hybrid, and the calcium-bromine (UT-3) cycles. Efficiencies of the S-I process are in the

    The major Canadian oil sands are located in Alberta and Saskatchewan, with most production from the strata along the Athabasca River in Alberta. The economically recoverable oil sands reserves are estimated to be 168 billion barrels which at a current production rate of 1.8 million barrels per day (2012), are projected to last a very long time. Canada has been blessed with vast energy resources which make it potentially energy-independent and able to provide significant exports but there are concerns that their development cannot be managed in a wholly acceptable manner. Comparable concerns have been applied to nuclear energy in the past and in recent times to the oil sands. The technologies associated with these energy sources have always been controversial because they are at the confluence of economics and politics where finding a balance between risk and reward is difficult. So it should be no surprise that when these technologies get linked together in certain proposals their prospect for success is doubly difficult. The possible use of nuclear energy for production of oil from the oil sands dates back to the late 1950s, when an experiment to mine the oil by detonating an underground nuclear device was proposed. It was predicted that the heat and pressure released from such a device would create a large cavern into which oil would flow, and from where it would be pumped to the surface. Almost at the same time, oil sands research using conventional sources of energy had culminated with the development of practical refining processes, essentially those still in use today. These methods require large amounts of heat energy in the form of hot water and steam. In this century nuclear energy was proposed as the source for the heat required by the oil sands production processes. To date neither of these nuclear proposals for oil sands projects have been successful, because the economic and political balance could not be struck. (author)

    Ando, Yoshio

    1981-01-01

    During the early 1960s, a plentiful, inexpensive supply of petroleum enabled Japanese industry to progress rapidly; however, almost all of this petroleum was imported. Even after the first oil crisis of 1973, the recent annual energy consumption of Japan is calculated to be about 360 million tons in terms of petroleum, and actual petroleum forms 73% of total energy. It is necessary for Japan to reduce reliance on petroleum and to diversify energy resources. The use of other fossil fuels, such as coal, LNG and LPG, and hydraulic energy, is considered as an established alternative. In this presentation, the author deals with new energy, namely soft energy and nuclear energy, and discusses their characteristics and problems. The following kinds of energy are dealt with: a) Solar energy, b) Geothermal energy, c) Ocean energy (tidal, thermal, wave), d) Wind energy, e) Biomass energy, f) Hydrogen, g) Nuclear (thermal, fast, fusion). To solve the energy problem in future, assiduous efforts should be made to develop new energy systems. Among them, the most promising alternative energy is nuclear energy, and various kinds of thermal reactor systems have been developed for practical application. As a solution to the long-term future energy problem, research on and development of fast breeder reactors and fusion reactors are going on. (author)

  1. The development of global energy supply as a succession of energy-related innovation processes. A qualitative model approach to assess the use of nuclear power

    International Nuclear Information System (INIS)

    Herrmann, Dieter

    2017-01-01

    Often, the development of the world energy supply is adopted as a painful sequence of the exhaustible and polluting use of primary energy sources. Therefore the expectations in practically inexhaustible and environmentally neutral renewable energy sources are high. However, in fact, it depends on the available production, conversion, and utilization technology, which sources of energy are suitable to meet given demands and requirements. In particular, the development of the energy demand requires energy technology innovations to use new energy sources, to use known energy sources more efficient and to replace exhaustible energy sources at an early stage by others. The historical development of the global energy supply is a sequence of interrelated energy technology innovation processes. This makes it also possible, to analyse the historical development of nuclear power and to derive a model on the future role of nuclear power worldwide.

    Speaking from the platform of the XIIIth annual session of the International Atomic Energy Agency, at New Delhi, AEC managing director Michel Pecqueur made a solemn appeal to the world community for the decisions which are needed on energy. The present energy crisis can lead the world to a recession and be a factor in grave troubles for peace and balance in the world. The crisis cannot be resolved without accrued recourse to the use of nuclear energy. Two essential themes were outlined: the development of nuclear energy in the world, and the increased reduction of proliferation risks. In concluding, he expressed the hop that with a greater effort in information media, the nuclear fact-of-life would be better accepted by the general public in future, for it is there that lies a brake which may hinder nuclear energy development [fr

    2006-01-01

    There are serious warnings about depletion of oil and gas and even more serious warnings about dangers of climate change caused by emission of carbon dioxide. Should developed countries be called to replace CO2 emitting energy sources as soon as possible, and the time available may not be longer then few decades, can nuclear energy answer the call and what are the requirements? Assuming optimistic contribution of renewable energy sources, can nuclear energy expand to several times present level in order to replace large part of fossil fuels use? Paper considers intermediate and long-term requirements. Future of nuclear power depends on satisfactory answers on several questions. First group of questions are those important for near and intermediate future. They deal with economics and safety of nuclear power stations in the first place. On the same time scale a generally accepted concept for radioactive waste disposal is also required. All these issues are in the focus of present research and development. Safer and more economical reactors are targets of international efforts in Generation IV and INPRO projects, but aiming further ahead these innovative projects are also addressing issues such as waste reduction and proliferation resistance. However, even assuming successful technical development of these projects, and there is no reason to doubt it, long term and large-scale nuclear power use is thereby not yet secured. If nuclear power is to play an essential role in the long-term future energy production and in reduction of CO2 emission, than several additional questions must be replied. These questions will deal with long-term nuclear fuel sufficiency, with necessary contribution of nuclear power in sectors of transport and industrial processes and with nuclear proliferation safety. This last issue is more political then technical, thus sometimes neglected by nuclear engineers, yet it will have essential role for the long-term prospects of nuclear power. The

    Until recently the nuclear industry information activity was of a purely factual nature (physical or technical processes); the aim for the future is to change from sender oriented information to recipient oriented communication. The starting point of the communication is the use of electrical energy in daily life; the first priority appears to be to answer questions relating not to the technical processes in nuclear power stations but to the direct effects of nuclear energy on the population. The activities programme should include school trips, active sponsoring, enhance teaching attractiveness

    Nuclear energy is a key attaining an integrated solution for energy security and global warming issues. Under the Framework for Nuclear Energy Policy Japan aims to (1) maintain the 30 to 40% or more share of nuclear energy on electricity generation up to 2030 and afterwards, (2) promote the nuclear fuel cycle and (3) commercialize the fast-breeder reactors. As for policies to realize the basic targets, the 'Nuclear Energy National Plan' was compiled in August 2006 as follows: (1) Investment to construct new nuclear power plants and replace existing reactors in an era of electric power liberalization, 2) Appropriate use of existing nuclear power plants with assuring safety as a key prerequisite, (3) Steady advancement of the nuclear fuel cycle and strategic reinforcement of nuclear fuel cycle industries, (4) Strategy to secure uranium supplied, (5) Early commercialization of the fast breeder reactor cycle, (6) Achieving and developing advanced, technologies, industries and personnel, (7) Assisting the Japanese nuclear industry in promoting the international development, (8) Involved in and/or creating international frameworks to uphold both nonproliferation and expansion of nuclear power generation, (9) Fostering trust between the sates and communities where plants are located by making public hearings and public relations highly detailed and (10) Steady promotion of measures for disposal of radioactive wastes. Implementation policies were presented in details in this book with relevant data and documents. (T. Tanaka)

    Nuclear energy has a strong relation to a society. However, due to accidents and scandals having occurred in recent years, people's reliability to nuclear energy has significantly swayed and is becoming existence of a worry. Analyzing such a situation and grasping the problem contained are serious problems for people engaging in nuclear field. In order that nuclear energy is properly used in society, communication with general public and in nuclear power plant site area are increasingly getting important as well as grasping the situation and surveying measures for overcoming the problems. On the basis of such an analysis, various activities for betterment of public acceptance of nuclear energy by nuclear industry workers, researchers and the government are proposed. (J.P.N.)

    With growing demand of energy and costs of the fossil fuels, coupled with the environmental concerns have resulted in an increased interest in alternative energy sources. Nuclear hybrid energy systems (NHES) are being considered which incorporates renewable energy sources such as solar and wind energy combined with nuclear reactor and energy storage to meet the peak hours demand imposed on the grid, along with providing process heat for other potential industrial applications. This concept could potentially satisfy various energy demands and improve reliability, robustness and resilience for the entire system as a whole, along with economic and net efficiency gains. This paper provides a brief understanding of potential NHES system and architecture along with the challenges

    2008-01-01

    The United States is facing unprecedented challenges in climate change and energy security. President-elect Obama has called for a reduction of CO2 emissions to 1990 levels by 2020, with a further 80% reduction by 2050. Meeting these aggressive goals while gradually increasing the overall energy supply requires that all non-emitting technologies must be advanced. The development and deployment of nuclear energy can, in fact, help the United States meet several key challenges: (1) Increase the electricity generated by non-emitting sources to mitigate climate change, (2) Foster the safe and proliferation-resistant use of nuclear energy throughout the world, (3) Reduce the transportation sector's dependence on imported fossil fuels, and (4) Reduce the demand on natural gas for process heat and hydrogen production. However, because of the scale, cost, and time horizons involved, increasing nuclear energy's share will require a coordinated research effort-combining the efforts of industry and government, supported by innovation from the research community. This report outlines the significant nuclear energy research and development (R and D) necessary to create options that will allow government and industrial decision-makers to set policies and create nuclear energy initiatives that are decisive and sustainable. The nuclear energy R and D strategy described in this report adopts the following vision: Safe and economical nuclear energy in the United States will expand to address future electric and non-electric needs, significantly reduce greenhouse gas emissions and provide energy diversity, while providing leadership for safe, secure and responsible expansion of nuclear energy internationally

    1976-01-01

    Mr. Goldfinger, Research Director of AFL-CIO, examines the problem of energy in general, nuclear in particular, and the employment relationship. The energy shortages in the U.S. and its dependence on oil are cited. Directly connected with this serious problem relating to energy are jobs, income, and living standards. If energy is not available, industries will be unable to expand to meet the needs of the growing population; and prices of goods will rise. From an evaluation of what experts have said, Mr. Goldfinger concludes that increased coal production and better coal technology cannot meet energy demands; so the sharp increase both in volume and as a percentage of total energy needed in the future will have to come from nuclear power. Development of alternative sources is necessary, he feels, and intense research on these is needed now. The employment impact in the nuclear energy scenario is analyzed according to the trades involved. It is estimated that 1.5 million jobs in the nuclear industry would be open by the year 2000 if nuclear is to provide one-fourth of energy supplies. The employment picture, assuming abandonment of nuclear energy, is then discussed

    The data presented in the different chapters lead to show that nuclear energy ids not a sustainable energy sources for the following reasons: investments in nuclear energy account financing that lacks to energy efficiency programmes. The nuclear programmes have negative effects such the need of great electric network, the need of highly qualified personnel, the freezing of innovation in the fields of supply and demand, development of small performing units. The countries resort to nuclear energy are among the biggest carbon dioxide emitters, because big size nuclear power plants lead to stimulate electric power consumption instead of inducing its rational use. Nuclear energy produces only electric power then a part of needs concerns heat (or cold) and when it is taken into account nuclear energy loses its advantages to the profit of cogeneration installations. Finally nuclear energy is a dangerous energy source, difficult to control as the accident occurring at Tokai MURA showed it in 1998. The problem of radioactive wastes is not still solved and the nuclear proliferation constitutes one of the most important threat at the international level. (N.C.)

    Radiation technology offers a very wide scope for utilisation and commercial exploitation in various fields. All over the world, this non-power nuclear energy is being favourably considered for different applications like radiation processing of polymeric materials, non-destructive testing, nuclear and nuclear-related analytical techniques, radiation sterilization of medical products and human tissue allografts, preservation of food by controlling the physiological processes for extending shelf-life and eradication of microbial and insect pests, nuclear technology in agriculture and treatment of sewage sludge. Bangladesh Atomic Energy Commission has taken radiation processing programmes in a big way right from its inception. This paper describes the studies carried out by various research groups in Bangladesh Atomic Energy Commission in the planning and development of non-power nuclear technology for peaceful uses in the fields of food, agriculture, medicine, industry and environment. Both food preservation and medical sterilization of medical products are now being commercially carried out in the Gammatech facility as a joint venture company of BAEC and a private entrepreneur. Bangladesh is soon going to establish a full-fledged Tissue Bank to cater the needs of various tissue allografts for surgical replacement. Recently Government of Bangladesh has allocated US$ 1.00 million for strengthening of the Tissue Banking Laboratory. Application of nuclear techniques in agriculture is also quite intensive. BAEC has made quite a good research contribution on vulcanization of natural rubber latex, wood plastic composites, surface coating curing, polymer modification etc. Bangladesh has also made a very good progress in the fields of non-destructive testing, tracer technology, nuclear analytical techniques and nucleonic control. The impact of non-power nuclear energy in selected areas will no doubt be significant in coming years. (Author)

    1998-01-01

    The global energy demand is increasing. Sound forecasts indicate that by the year 2020 almost eight thousand million people will be living on our planet, and generating their demand for energy will require conversion of about 20 thousand million tonnes of coal equivalents a year. Against this background scenario, a new concept for energy generation elaborated by nuclear scientists at CERN attracts particular interest. The concept describing a new nuclear energy source and technology intends to meet the following principal requirements: create a new energy source that can be exploited in compliance with extremely stringent safety requirements; reduce the amount of long-lived radioactive waste; substantially reduce the size of required radwaste repositories; use easily available natural fuels that will not need isotopic separation; prevent the risk of proliferation of radioactive materials; process and reduce unwanted actinides as are generated by the operation of current breeder reactors; achieve high efficiency both in terms of technology and economics.

    The engineering level of the development of atomic rocket engineering has made it possible to consider various types of nuclear reactors as possible electricity sources to support petrochemical processes at petrochemical plants (using vapor, heat, electricity and radiation energies). The use of energy from nuclear reactors in combination with the elimination of liquid and gas fuels used in the furnaces will make it possible to improve the ecological situation in the vicinity of the plant, to accelerate petroleum processing and oil processing processes and to improve the cost effectiveness of nuclear engineering complexes to a degree related to the total capacity of the industrial complexes and the degree of comprehensive utilization of energy from the nuclear reactors.

    After an introduction recalling what energy is, the first part of this book presents the present day energy production and consumption and details more particularly the electricity 'vector' which is an almost perfect form of energy despite the fact that it is not a primary energy source: it must be generated from another energy source and no large scale storage of this energy is possible. The second part of the book is devoted to nuclear energy principles and to the related technologies. Content: 1 - What does energy mean?: the occurrence of the energy concept, the classical notion of energy, energy notion in modern physics, energy transformations, energy conservation, irreversibility of energy transformations, data and units used in the energy domain; 2 - energy production and consumption: energy systems, energy counting, reserves and potentialities of energy resources, production of primary energies, transport and storage of primary energies, energy consumption, energy saving, energy markets and prices, energy indicators; 3 - electric power: specificity of electricity and the electric system, power networks, power generation, electricity storage, power consumption and demand, power generation economics, electricity prices and market; 4 - physical principles of nuclear energy: nuclei structure and binding energy, radioactivity and nuclear reactions, nuclear reactions used in energy generation, basics of fission reactors physics; 5 - nuclear techniques: historical overview, main reactor types used today, perspectives; 6 - fuel cycle: general considerations, uranium mining, conversion, enrichment, fuel fabrication, back-end of the cycle, plutonium recycle in water cooled reactors; 7 - health and environmental aspects of nuclear energy: effects on ionizing radiations, basics of radiation protection, environmental impacts of nuclear energy, the nuclear wastes problem, specific risks; 8 - conclusion; 9 - appendixes (units, physics constants etc..)

    We have developed a new method to propagate the uncertainties of fundamental nuclear physics models and parameters to the design and performance parameters of future, clean nuclear energy systems. Using Monte Carlo simulation, it is for the first time possible to couple these two fields at the extremes of nuclear science without any loss of information in between. With the help of a large database of nuclear reaction measurements, we have determined the uncertainties of theoretical nuclear reaction models such as the optical, compound nucleus, pre-equilibrium and fission models. A similar assessment is done for the parameters that describe the resolved resonance range. Integrating this into one simulation program enables us to describe all open channels in a nuclear reaction, including a complete handling of uncertainties. Moreover, in one and the same process, values and uncertainties of nuclear reactor parameters are computed. This bypasses all the intermediate steps which have been used so far in nuclear data and reactor physics. Two important results emerge from this work: (a) we are able to quantify the required quality of theoretical nuclear reaction models directly from the reactor design requirements and (b) our method leads to a deviation from the commonly assumed normal distribution for uncertainties of safety related reactor parameters, and this should be taken into account for future nuclear energy development. In particular, calculated k eff distributions show a high-value tail for fast reactor spectra

    This report gives the results of considerations on industrial heat and technology processes (in chemistry, steelmaking, etc.) from the point of view of possible ways, technical conditions and nuclear safety requirements for the use of high temperature reactors in these processes. Possible variants of energy-technological diagrams of nuclear-steelmaking, methane steam-reforming reaction and other processes, taking into account the specific character of nuclear fuel are also given. Technical possibilities and economic conditions of the usage of different types of high temperature reactors (gas cooled reactors and reactors which have other means of transport of nuclear heat) in heat processes are examined. The report has an analysis of the problem, that arises with the application of nuclear reactors in energy-technological plants and an evaluation of solutions of this problem. There is a reason to suppose that we will benefit from the use of high temperature reactors in comparison with the production based on high quality fossil fuel [ru

    The challenge for the nuclear community is to assure that nuclear power remains a viable option in meeting the energy requirements of the next century. It could be a major provider of electricity for base load as well as for urban transport in megacities. It can play a role in non-electric applications in district heating, process industries, maritime transport. (author)

    A study about the perspectives of nuclear energy, in Japan, for the next 40 years is shown. The present tendencies are analyzed as well as the importance that the subject adquires for the economy and the industry. At the same time, the parameters of the governmental, private and foreign participation are established in the frame of the technological development. The aim fixed for the year 2030 can be divided into; 1: from 1986 to 2010-development of the technology of nuclear fuel cycle already stablished and in process of maturity. The LWR technology will reach a very advanced stage. The fast breeder reactors (FBRs) will become commercially available, and the nuclear fuel cycle will reach its maturity in Japan; 2: from 2011 to 2030-commercial use of the FBRS and further advance in the nuclear fuel cycle.

    According to the 'framework for nuclear energy policy' (October, 2005 adopted by cabinet), basic goals of nuclear policy are (1) for nuclear energy to continue to meet more than around 30-40% of electricity supply, and also (2) to further promote a fuel cycle steadily aiming at commercial introduction of a fast breeder by 2050. In order to realize an aim of this framework for nuclear energy policy', the nuclear energy subcommittee of the METI advisory committee deliberated concrete actions and the subcommittee recommendations were drawn up as 'Japan's nuclear energy national plan' in August, 2006 and incorporated as main part of the revised 'basic plan on energy' adopted by the cabinet in March 2007. Backgrounds and directions of future actions for nuclear energy policy were described. (T. Tanaka)

  14. Nuclear energy outlook 2008

    International Nuclear Information System (INIS)

    2008-01-01

    With the launch today of its first Nuclear Energy Outlook, the OECD Nuclear Energy Agency (NEA) makes an important contribution to ongoing discussions of nuclear energy's potential role in the energy mixes of its member countries. As world energy demand continues to grow unabated, many countries face serious concerns about the security of energy supplies, rising energy prices and climate change stemming from fossil fuel consumption. In his presentation, the NEA Director-General Luis Echavarri is emphasizing the role that nuclear power could play in delivering cost-competitive and stable supplies of energy, while also helping to reduce greenhouse gas emissions. In one Outlook scenario, existing nuclear power technologies could provide almost four times the current supply of nuclear-generated electricity by 2050. Under this scenario, 1400 reactors of the size commonly in use today would be in operation by 2050. But in order to accomplish such an expansion, securing political and societal support for the choice of nuclear energy is vital. An ongoing relationship between policy makers, the nuclear industry and society to develop knowledge building and public involvement will become increasingly important, the publication notes. Moreover, governments have a clear responsibility to maintain continued effective safety regulation, advance efforts to develop radioactive waste disposal solutions and uphold and reinforce the international non-proliferation regime. The authors find that the security of energy from nuclear power is more reliable than that for oil or gas. Additionally, uranium's high energy density means that transport is less vulnerable to disruption, and storing a large energy reserve is easier than for fossil fuels. One tonne of uranium produces the same energy as 10 000 to 16 000 tonnes of oil using current technology. Ongoing technological developments are likely to improve that performance even more.

    With rapid economic development, China faces a great challenge to meet its increasing energy demand. Currently, China's energy supply is dominated by coal consumption, while natural gas and oil are in relative short supply. At the same time, nuclear energy is a relatively clean energy without green-house gas emissions. Considering the growing cost of fossil energy and the limited resources in China, oil supply security, coal mining disasters, the domestic environment pressure, and global climate warming, nuclear energy is an inevitable strategic option. Generally speaking, nuclear energy development has a promising future in China. Its driving factors include the brisk electricity demand, environment impact pressure, oil supply security, and positive public acceptance. Meanwhile, the question still remains whether nuclear energy development in China is sustainable. Just like in other parts of the world, China is also bewildered by the problems of reactor safety, nuclear waste treatment, and risk of proliferation of weapons material. In addition, nuclear technology diversity, shortage of uranium resources, and weak market competitiveness of nuclear power in the short term are certain barriers that China's nuclear energy development also faces. There are also other worrying issues such as: whether public acceptance in the future will change? Whether the current approaches to nuclear waste disposal are still acceptable when nuclear plants gains scale? In this paper, some suggestions and recommendations are put forward on the measures to be followed to 1) enhance domestic nuclear technology development and imported technology localization; 2) reduce the cost of nuclear power and enhance its market competitiveness; 3) accelerate the process of cleanly developing nuclear technology; 4) accelerate the process of developing more efficient reactor and nuclear fuel cycle; and 5) conduct effective publicity work to uphold public acceptance.

    Fuel is essential for development whether for survival and or wealth creation purposes. In this century the utilization of fuels need to be improved although energy mix is still to be the most rational choice. The large amount utilization of un-renewable fossil has some disadvantages since its low energy content requires massive extraction, transport, and processing while emitting CO 2 resulting degradation of the environment. In the mean time the advancement of nuclear science and technology has improved significantly the performance of nuclear power plant management of radioactive waste, enhancement of proliferation resistance, and more economic competitiveness. Ever since the last decade of the last century the nuclear renaissance has taken place. This is also due to the fact that nuclear energy does not emit GHG. Although the nuclear fuel offers a virtually limitless source of economic energy, it is only so if the nuclear fuel is reprocessed and recycled. Consequently, the fuel cycle is to be even more of paramount important in the future. The infrastructure of the fuel cycle services world wide has been adequately available. Various International Initiatives to access the fuel cycle services are also offered. However, it is required to put in place the International Arrangements to guaranty secured sustainable supply of services and its peaceful use. Relevant international cooperations are central for proceeding with the utilization of nuclear energy, while this advantagous nuclear energy utilization relies on the fuel cycle services. It is therefore concluded that the fuel cycle services are the heart of nuclear energy, and the international nuclear community should work together to maintain the availability of this nuclear fuel cycle services timely, sufficiently, and economically.

    This summary represents an overview of the energy situation in Armenia and, in particular, the nuclear energy development during the last period of time. the energy sector of Armenia is one of the most developed economy branches of the country. The main sources of energy are oil products, natural gas, nuclear energy, hydropower, and coal. In the period of 1985-1988 the consumption of these energy resources varied between 12-13 million tons per year of oil equivalent. Imported energy sources accounted for 96% of the consumption. During the period 1993-1995 the consumption dropped to 3 million tons per year. Electricity in Armenia is produced by three thermal, one nuclear, and two major hydroelectric cascades together with a number small hydro units. The total installed capacity is 3558 MW. Nuclear energy in Armenia began its development during the late 1960's. Since the republic was not rich in natural reserves of primary energy sources and the only domestic source of energy was hydro resource, it was decided to build a nuclear power plant in Armenia. The Armenian Nuclear Power Plant (ANPP) Unit 1 was commissioned in 1996 and Unit 2 in 1980. The design of the ANPP was developed in 1968-1969 and was based on the project of Units 3 and 4 of the Novovoronezh NPP. Both units of the plant are equipped with reactors WWER-440 (V -270) type, which are also in use in some power stations in Russian Federation, Bulgaria, and Slovakia. Currently in Armenia, 36% of the total electricity production is nuclear power electricity. (authors)

    As the depletion of energy resources, their unequal use by a rich world on the one hand and developing countries on the other hand will be the key issues for a necessary energy transition, and as these issues come along the problem of climate change, the author more particularly discusses the French situation and perspectives. He discusses and compares the benefits, risks and drawbacks of nuclear energy (a rather clean energy in terms of greenhouse gas emission) with that of other energy sources. He also discusses and compares the possible scenarios of energy transition for France on a medium and on a long term. After some generalities on the military and civil use of nuclear energy (risks associated with nuclear energy, cost of nuclear energy), he proposes an overview of geopolitical aspects related to energy (relationship between demography and energy, actual and estimated energy sources). He describes the main elements of nuclear physics (atom structure, neutron reactions, thermonuclear fusion, radioactivity, exposure sources and regulation), and presents the various nuclear technologies (historical evolution, operation principles of nuclear power plants, nuclear technologies, PWR design and return on experience, EPR, the experimental ITER reactor). He recalls and comments the main nuclear accidents and their consequences (Three Mile Island, Chernobyl, Fukushima), addresses the issue of nuclear wastes (origin, processing and storage, packaging and management for the different types of wastes). Then, he addresses the climate issue and more particularly the greenhouse effect and its impact on climate. The next chapter proposes an overview of the world electricity production and consumption and of the production of renewable energies. The author compares the costs of the different technologies of electricity production, and then discusses the perspectives in terms of energy price, energy and electricity demand by different sectors

    2007-12-01

    Developing nuclear energy that is sustainable, safe, has little waste by-product, and cannot be proliferated is an extremely vital and pressing issue. To resolve the four issues through free thinking and overall vision, research activities of 'innovative nuclear energy systems' and 'innovative separation and transmutation' started as a unique 21st Century COE Program for nuclear energy called the Innovative Nuclear Energy Systems for Sustainable Development of the World, COE-INES. 'Innovative nuclear energy systems' include research on CANDLE burn-up reactors, lead-cooled fast reactors and using nuclear energy in heat energy. 'Innovative separation and transmutation' include research on using chemical microchips to efficiently separate TRU waste to MA, burning or destroying waste products, or transmuting plutonium and other nuclear materials. Research on 'nuclear technology and society' and 'education' was also added in order for nuclear energy to be accepted into society. COE-INES was a five-year program ending in 2007. But some activities should be continued and this roadmap detailed them as a rough guide focusing inventions and discoveries. This technology roadmap was created for social acceptance and should be flexible to respond to changing times and conditions. (T. Tanaka)

  4. Quantum nuclear pasta and nuclear symmetry energy

    Science.gov (United States)

    2017-05-01

    Complex and exotic nuclear geometries, collectively referred to as "nuclear pasta," are expected to appear naturally in dense nuclear matter found in the crusts of neutron stars and supernovae environments. The pasta geometries depend on the average baryon density, proton fraction, and temperature and are critically important in the determination of many transport properties of matter in supernovae and the crusts of neutron stars. Using a set of self-consistent microscopic nuclear energy density functionals, we present the first results of large scale quantum simulations of pasta phases at baryon densities 0.03 ≤ρ ≤0.10 fm-3 , proton fractions 0.05 ≤Yp≤0.40 , and zero temperature. The full quantum simulations, in particular, allow us to thoroughly investigate the role and impact of the nuclear symmetry energy on pasta configurations. We use the Sky3D code that solves the Skyrme Hartree-Fock equations on a three-dimensional Cartesian grid. For the nuclear interaction we use the state-of-the-art UNEDF1 parametrization, which was introduced to study largely deformed nuclei, hence is suitable for studies of the nuclear pasta. Density dependence of the nuclear symmetry energy is simulated by tuning two purely isovector observables that are insensitive to the current available experimental data. We find that a minimum total number of nucleons A =2000 is necessary to prevent the results from containing spurious shell effects and to minimize finite size effects. We find that a variety of nuclear pasta geometries are present in the neutron star crust, and the result strongly depends on the nuclear symmetry energy. The impact of the nuclear symmetry energy is less pronounced as the proton fractions increase. Quantum nuclear pasta calculations at T =0 MeV are shown to get easily trapped in metastable states, and possible remedies to avoid metastable solutions are discussed.

    France has the ambition to become a world leader in both nuclear industry and in renewable energies. 3 types of synergies between nuclear power and renewable energies are highlighted. First, nuclear power can be used as a low-carbon energy to produce the equipment required to renewable energy production for instance photovoltaic cells. Secondly, to benefit from the complementary features of both energies: continuous/intermittency of the production, centralized/local production. The future development of smart grids will help to do that. Thirdly, to use nuclear energy to produce massively hydrogen from water and synthetic fuels from biomass. (A.C.)

    If nuclear energy is to realize its full potential as a safe and cost-effective alternative to fossil fuels, applications beyond those that are currently being serviced by large, central nuclear power stations must be identified and appropriate reactors developed. The Canadian program on reactor systems for local energy supply is at the forefront of these developments. This program emphasizes design simplicity, low power density and fuel rating, reliance on natural processes, passive systems, and reduced reliance on operator action. The first product, the SLOWPOKE Energy System, is a 10 MW heat source specifically designed to provide hot water to satisfy the needs of local heating systems for building complexes, institutions and municipal district heating systems. A demonstration heating reactor has been constructed at the Whiteshell Nuclear Research Establishment in Manitoba and has been undergoing an extensive test program since first operation in 1987 July. Based on the knowledge learned from the design, construction, licensing and operational testing of this facility, the design of the 10 MW commercial-size unit is well advanced, and Atomic Energy of Canada Limited is prepared to commit the construction of the first commercial unit. Although the technical demonstration of the concept is important, it is recognized that another crucial element is the public and regulatory acceptance of small nuclear systems in urban areas. The decision by a community to commit the construction of a SLOWPOKE Energy System brings to a sharp focus the current public apprehension about nuclear technologies

    Australian authorities have been traditionally opposed to nuclear energy. The interdiction to build nuclear power plants in the Australian states without the approval of the federal authority was even officially written in the environment code in 1999. Today coal provides 75% of the electricity needs of Australia. Because of climate warming, things are changing, the Australian government is now considering the possibility of using nuclear energy and a site located in southern Australian has been selected for the disposal of low and intermediate level radioactive wastes. In this context the Australian Nuclear Association (ANA) is developing an ambitious program for the promotion of all the applications of nuclear energy through the organisation of conferences and meetings with various experts of nuclear industry. The aim is to make the public aware of the assets of nuclear energy. (A.C.)

Information provided by governments includes statistics on total electricity produced by all sources and by nuclear power, fuel cycle capacities and requirements, and projections to 2035, where available. Country reports summarise energy policies, updates of the status in nuclear energy programs and fuel cycle developments. In 2016, nuclear power continued to supply significant amounts of low-carbon baseload electricity, despite strong competition from low-cost fossil fuels and subsidised renewable energy sources. Three new units were connected to the grid in 2016, in Korea, Russia and the United States. In Japan, an additional three reactors returned to operation in 2016, bringing the total to five under the new regulatory regime. Three reactors were officially shut down in 2016 - one in Japan, one in Russia and one in the United States. Governments committed to having nuclear power in the energy mix advanced plans for developing or increasing nuclear generating capacity, with the preparation of new build projects making progress in Finland, Hungary, Turkey and the United Kingdom.

Information provided by member country governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies and fuel cycle developments, as well as projected generating capacity and electricity production to 2035, where available. Total electricity generation at nuclear power plants and the share of electricity production from nuclear power plants declined in 2012 as a result of operational issues at some facilities and suspended operation at all but two reactors in Japan. Nuclear safety was further strengthened in 2012 following safety reviews prompted by the Fukushima Daiichi nuclear power plant accident. Governments committed to maintaining nuclear power in the energy mix pursued initiatives to increase nuclear generating capacity. In Turkey, plans were finalised for the construction of the first four reactors for commercial electricity production. Further details on these and other developments are provided in the publication's numerous tables, graphs and country reports. This publication contains 'Statlinks'.

This is also a sensitive topic among the opponents and proponents of the nuclear energy in Turkey. Nuclear energy is very important since it provides about 17 % of the electric energy in the world and is used in industry and medical area. However, Turkey has not declared any policy about this yet, because of the worries about the environmental reasons and has not gained any progress about nuclear energy. First of all, Turkey must use her geothermal, hydropower, hard coal, solar and wind energies. Otherwise, Turkey may find herself in a competition with her neighboring countries

    The wide use of nuclear energy has promoted the development of China's economy and the improvement of people's living standards. To some extent, the exploitation of nuclear power plants will solve the energy crisis faced with human society. Before the utilization of nuclear fusion energy, nuclear fission energy will be greatly needed for the purpose of alleviating energy crisis for a long period of time. Compared with fossil fuel, on the one hand, nuclear fission energy is more cost-efficient and cleaner, but on the other hand it will bring about many problems hard to deal with, such as the reprocessing and disposal of nuclear spent fuel, the contradiction between nuclear deficiency and nuclear development. This paper will illustrate the future and prospect of nuclear energy from the perspective of the difficulty of nuclear development, the present reprocessing way of spent fuel, and the measures taken to ensure the sustainable development of nuclear energy. By the means of data quoting and comparison, the feasibility of sustainable development of nuclear energy will be analyzed and the conclusion that as long as the nuclear fuel cycling system is established the sustainable development of nuclear energy could be a reality will be drawn.

    The main concern of Pugwash, with very good reason, is nuclear disarmament, but a negative attitude towards nuclear energy is not only futile, but counterproductive as it misses opportunities to appropriately influence its development. Since nuclear energy cannot be abandoned for ecological (decrease in greenhouse gases emission) and economic reasons as a long term energy source, then efforts should be devoted to make it safe from proliferation, which is possible from scientific and technological point of view

    Quasifree nucleon processes are expected to dominate the nuclear electromagnetic response function for large energy and momentum transfers, i.e., for energy transfers large compared with nuclear single particle energies and momentum transfers large compared with typical nuclear momenta. Despite the evident success of the quasifree picture in providing the basic frame work for discussing and understanding the large energy, large momentum nuclear response, the limits of this picture have also become quite clear. In this article a selected set of inclusive and coincidence data are presented in order to define the limits of the quasifree picture more quantitatively. Specific dynamical mechanisms thought to be important in going beyond the quasifree picture are discussed as well. 75 refs, 37 figs

    The paper describes the 'pro-nuclear' sector of the Romanian civil society activity to better inform the Romanian Decision Makers on nuclear power issues. The 'Romanian Nuclear Energy Association' - AREN and the Romanian Radioprotection Society - SRRp, having the support of the 'Romanian General Association of Engineers' - AGIR, started on December 1996 a strong campaign to form a correct opinion among the new elected bodies and the new Government of the country, related to the future development of the Romanian Nuclear Program as a national priority and to expedite the restart of the Cernavoda NPP-Unit 2 completion. The paper describes the strategy of this lobby campaign, the objectives assumed and the results. The authors have taken advantage of the OECD - Nuclear Energy Agency information exchange about the Decision Makers informing process about nuclear energy and have the intention to share their experience with other sister societies dealing with similar conditions. This could be also a good experience for other areas of activity. (authors)

    Fossil fuels such as coal oil, and gas, massively pollute the Earth atmosphere (CO, CO 2 , SOX, NOX...), provoking acid rains and changing the global climate by increasing the greenhouse effect, while nuclear energy does not participate in these pollutions and presents well-founded environmental benefits. Renewable energies (solar, wind) not being able to deliver the amount of energy required by populations in developing and developed countries, nuclear energy is in fact the only clean and safe energy available to protect the planet during the 21 century. The first half of the book, titled The Atomic Paradox, describes in layman language the risks of nuclear power, its environmental impact, quality and safety standards, waste management, why a power reactor is not a bomb, energy alternatives, nuclear weapons, and other major global and environmental problems. In each case the major conclusions are framed for greater emphasis. Although examples are taken from the French nuclear power program, the conclusions are equally valid elsewhere. The second half of the book is titled Information on Nuclear Energy and the Environment and briefly provides a historical survey, an explanation of the different types of radiation, radioactivity, dose effects of radiation, Chernobyl, medical uses of radiation, accident precautions, as well as a glossary of terms and abbreviations and a bibliography.

    A galvanic cell and methods of using the galvanic cell is described for the recovery of uranium from used nuclear fuel according to an electrofluorination process. The galvanic cell requires no input energy and can utilize relatively benign gaseous fluorinating agents. Uranium can be recovered from used nuclear fuel in the form of gaseous uranium compound such as uranium hexafluoride, which can then be converted to metallic uranium or UO.sub.2 and processed according to known methodology to form a useful product, e.g., fuel pellets for use in a commercial energy production system.

    Nuclear Energy Data is the OECD Nuclear Energy Agency's annual compilation of statistics and country reports documenting the status of nuclear power in the OECD area. Information provided by member country governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies and fuel cycle developments, as well as projected generating capacity and electricity production to 2035, where available. Total electricity generation at nuclear power plants and the share of electricity production from nuclear power plants remained steady in 2013 despite the progressive shutdown of all reactors in Japan leading up to September and the permanent closure of six reactors in the OECD area. Governments committed to maintaining nuclear power in the energy mix advanced plans for increasing nuclear generating capacity, and progress was made in the development of deep geological repositories for spent nuclear fuel, with Finland expected to have the first such facility in operation in the early 2020's. Further details on these and other developments are provided in the publication's numerous tables, graphs and country reports. This publication contains 'StatLinks'. For each StatLink, the reader will find a URL which leads to the corresponding spreadsheet. These links work in the same way as an Internet link. (authors)

    We have not been able to obtain closure in the nuclear energy debate because the public perception of nuclear energy is out of sync with reality. The industry has not been about to deal with the concerns of those opposed to nuclear energy because its reaction has been to generate and disseminate more facts rather than dealing with the serious moral and ethical questions that are being asked. Nuclear proponents and opponents appeal to different moral communities, and those outside each community cannot concede that the other might be right. The Interfaith Program for Public Awareness of Nuclear Issues (IPPANI) has been formed, sponsored by members of the Jewish, Baha'i, Roman Catholic, United, and Anglican faiths, to provide for a balanced discussion of the ethical aspects of energy.

    Energy is a social concept, the product of social, economic, and political processes that define certain raw materials as resources and thus convert them into usable energy. Like all social concepts, energy is controversial. Out of a wide range of controversies, three are selected for analysis here: (1) the relationship of nuclear power systems to nuclear weapons proliferation; (2) the risks of terrorism and sabotage associated with the operation of nuclear power facilities, including threats to civil liberties; and (3) the problems associated with the long-term management of radioactive wastes. The final section of the paper describes various modes of analyzing risks and the perception of risks. It is concluded that it may take many decades to learn whether nuclear energy is as natural a source of electrical power as wells are of drinking water, or whether nuclear energy is a horror that mankind in the 1980s or 1990s took a hard look at and then backed away.

    Japan has scant energy resources, and more than 80% of its energy demand depends on other countries. The energy problem should be considered not only from the domestic viewpoint of energy supply and demand but also from the global viewpoint. Japanese nuclear power generation accounts for about 30% of its total electric power. The main strategy of Japan is to secure stable energy supply through the establishment of nuclear fuel cycle, and to efficiently use the plutonium and residual uranium recovered from spent nuclear fuel. The sodium leakage from the prototype FBR 'Monju' in December, 1995 raised the anxiety about the nuclear policy. People living in Japan should be assured the peace of mind about the development and utilization of nuclear energy. Regarding coexistence of nuclear energy and people, stronger demand of clearer reflection of public opinion to nuclear policy, holding of the round table conferences on nuclear policy, various efforts toward the coexistence of nuclear energy and people and so on are discussed. The development and utilization of nuclear energy in Japan and overseas are reported on nuclear nonproliferation, safety assurance, information disclosure, present and future of nuclear power generation, international cooperation and others.

    2002-01-01

    This paper analyzes the view expressed by the Japanese government on the role of nuclear energy for energy security through scrutiny of Japan's policy documents. The analysis revealed that the contribution by nuclear energy to Japan's energy security has been defined in two ways. Nuclear energy improves short-term energy security with its characteristics such as political stability in exporting countries of uranium, easiness of stockpiling of nuclear fuels, stability in power generation cost, and reproduction of plutonium and other fissile material for use by reprocessing of spent fuel. Nuclear energy also contributes to medium- and long-term energy security through its characteristics that fissile material can be reproduced (multiplied in the case of breeder reactor) from spent fuels. Further contribution can be expected by nuclear fusion. Japan's energy security can be strengthened not only by expanding the share of nuclear energy in total energy supply, but also by improving nuclear energy's characteristics which are related to energy security. Policy measures to be considered for such improvement will include (a) policy dialogue with exporting countries of uranium, (b) government assistance to development of uranium mines, (c) nuclear fuel stockpiling, (d) reprocessing and recycling of spent fuels, (e) development of fast breeder reactor, and (f) research of nuclear fusion.

    China receives attention from the whole world as not only have they become a country spending the most energy in the world, but also the amount of energy they need is still increasing. Consequently, many problems related to environmental pollution have occurred in China. Recently, China agreed to reduce carbon emission in order to deal with this issue. Therefore, they need to find energy sources other than fossil fuel; the nuclear energy could be an alternative. In addition, it is considered to be a base load owing to its low fuel cost and continuation of electricity generation. In reality, the Chinese government is planning to build about 400 Nuclear Power Plants (NPPs) up to 2050. Therefore, it is expected that China will become a giant market in the nuclear industry. It could give us either chances to join the huge market or challenges to meet not merely nuclear fuel price crisis but competitors from China in the world nuclear power plant market. In any case, it is obvious that the energy policy of China would influence us significantly. Accordingly, we need appropriate prediction of the Chinese nuclear industry to cope with the challenges.

  17. Is nuclear energy ethically justifiable?

    International Nuclear Information System (INIS)

    Zuend, H.

    1988-01-01

    Nuclear technology brings the chance to provide an essential long term contribution to the energy supply of the world population and to use the raw materials uranium and thorium which have no other use. The use of nuclear energy is ethically justifiable providing certain simple fundamental rules for the design of nuclear facilities are observed. Such rules were clearly violated before the reactor accident at Chernobyl. They are, however, observed in our existing nuclear power plants. Compared with other energy systems nuclear energy has, with the exception of natural gas, the lowest risk. The consideration of the ethical justification of nuclear energy must also include the question of withdrawal. A withdrawal would have considerable social consequences for the industrial nations as well as for the developing countries. The problem of spreading alarm (and concern) by the opponents of nuclear energy should also be included in the ethical justification. 8 refs., 2 figs

    Nuclear fission has been investigated with the double-kinetic-energy method using silicon surface barrier detectors. Fragment energy correlation measurements have been made for U, Th and Bi with bremsstrahlung of 600 MeV maximum energy. Distributions of kinetic energy as a function of fragment mass are presented. The results are compared with earlier photofission data and in the case of bismuth, with calculations based on the liquid drop model. The binary fission process in U, Yb, Tb, Ce, La, Sb, Ag and Y induced by 600 MeV protons has been investigated yielding fission cross sections, fragment kinetic energies, angular correlations and mass distributions. Fission-spallation competition calculations are used to deduce values of macroscopic fission barrier heights and nuclear level density parameter values at deformations corresponding to the saddle point shapes. We find macroscopic fission barriers lower than those predicted by macroscopic theories. No indication is found of the Businaro Gallone limit expected to occur somewhere in the mass range A = 100 to A = 140. For Ce and La asymmetric mass distributions similar to those in the actinide region are found. A method is described for the analysis of angular correlations between complementary fission products. The description is mainly concerned with fission induced by medium-energy protons but is applicable also to other projectiles and energies. It is shown that the momentum and excitation energy distributions of cascade residuals leading to fission can be extracted. (Author)

    With 15% of the world's population and an economic growth rate that increases the aspiration of its people to better quality of life, India has a voracious appetite for energy. Nuclear power is one of the options of providing safe, environmentally benign, reliable and economically competitive energy services. Nuclear power world over provides about 16% of electricity through 440 nuclear power plants with a total installed capacity of 361.582 GW (as of January 2004, IAEA PRIS data). Nuclear energy has traditionally played a small role in meeting India's energy requirements. Nuclear power makes up only 4,120 MW, constituting 2.6%, of the total electricity generation capacity. India is a power hungry nation and needs to switch over from its tremendous dependence on fossil fuels to alternative sources of energy like solar energy, bio energy and nuclear energy. Indian nuclear power plants have progressively attained excellent operation performances. However, the changing economic and geopolitical situation in the energy sector has made it imperative to emphasize the significance of nuclear energy in the future energy landscape of the country. The present paper discuss the importance, demand and supply pattern of nuclear energy and its economics. (author)

    Higher knowledge has long been hypothesized as leading to better acceptance of nuclear energy, but in the last years other factors such as risk perception and trust in nuclear risk governance were also recognized as key elements. While stakeholder involvement is now fully recognized as a key element for nuclear energy acceptance, there are still questions about the impact of higher knowledge. This paper investigates the relation between knowledge about the nuclear domain, risk perception of nuclear risks, confidence in the management of nuclear technologies, on the one hand, and the attitude towards nuclear energy and opinion about nuclear energy, on the other hand. It also studies the factors that are pleading in favour or against nuclear energy and their relation with the forementioned variables. The study is based on empirical data from a large scale opinion survey in Belgium between 25/05/2011 and 24/06/2011, i.e. the third month after the accident in Fukushima. The sample consisted of 1020 respondents and is representative for the Belgian adult population (18+) with respect to gender, age, region, province, habitat and social class. Our results show that confidence in the safe management of nuclear technologies as well as the perceived strength of the arguments pro/against nuclear are driving factors for people's attitude towards nuclear energy. Higher confidence and stronger adherence to the arguments in favour of nuclear energy lead to higher acceptance. The correlation between knowledge and attitude/opinion towards nuclear energy is statistically significant, but rather low, showing only a weak effect of knowledge on attitudes or opinions about nuclear energy. A weak effect is also observed for risk perception of nuclear risks, lower risk perception leading to a somewhat more positive attitude/opinion about nuclear energy. In the study we also highlight that the main factors seen as pleading in favour or against nuclear energy are the same, both for

    The total electricity generated in 1998 was 215,300 GWh with 43,261 MWe of total installed capacity of electric power, while in 1978 when the first Nuclear Power Plant began operation it was 31,510 GWh with 6,916 MWe installed capacity. The share of nuclear power generation in 1998 increased up to 41.7%. Currently, 16 units of nuclear power are operating with an additional four units under construction. Nuclear power has contributed to enhancing energy security and supplying stable energy for Korea. The government's strong commitment to the nuclear power program together with a long-term national policy resulted in favorable conditions for KEPCO to manage the program and promote increasing levels of national participation in successive nuclear power projects. The role of nuclear power as a sustainable energy resource can not be emphasized enough with respect to global environmental issues. Increasing the share of nuclear power in the total installed capacity for electricity generation will undoubtedly play a very important role. (author)

  5. Nuclear energy and public opinion - a difficult relationship

    Kaase, M.

    1990-01-01

    Nuclear energy remains an explosive subject. Less people demand to give up nuclear energy at once but the emotional and cognitive environment of attitudes to nuclear energy makes this relative 'peaceabilty' seem a very precarious issue. The Chernobyl shock is still active. The future will depend on whether new accidents will occur in nuclear power stations and how dangerous they will be. The highly political nature and the polarization of the subject together with an assumingly still negative coverage by the mass media and a general distrust of the people in established politics will make it very difficult to influence attitudes by means of information. We should attempt to bring sober facts and objectiveness to the discussion of nuclear energy and to involve citizens more actively than in the past while ensuring that there is less auto-selectivity (bias). What we also need is the basic and credible readiness of all participants to accept the results of a democratic process of the development of opinion. (orig./HSCH) [de

Any realistic spectator will not deny the fact that common sense and reason are fairly absent from the discussions about energy and nuclear energy. However, common sense and reason will win the day in the long run - either through insight or, short of that, through coercion and sacrifices. (orig./HSCH) [de

    The paper 'Political culture, national identity and nuclear energy. The austrian controversy on nuclear energy between 1978 and 1986 within the national assembly' identifies the roots of the broad rejection of nuclear technologies in contemporary Austria within the controversy on neclear energy in the late 1970s and early 1980s. The close result of the referendum in November 1978 on the commissioning of the nuclear power plant in Zwentendorf - understood as a moment of severe polarisation - serves as a starting point for the investigation. In recent studies the explosion of the reactor in Chernobyl in April 1986 is considered the turning point of the austrian controversy and therefore marks the end of the examined period. Reviewing the history of nuclear energy in Austria the paper sheds light on events and aspects which turn out to be important for the rejection of nuclear technologies in contemporary Austria. On the one hand the analysis of the nuclear debate within the national assembly focuses on ways in which nuclear technologies were made sense of and ascribed with meaning and describes them as a sociotechnical imaginary. Next to highlighting the construction of national identity within these processes the analysis on the other hand explores the role of consensus and mutual action within the political culture of the Second Republic and its implications for the nuclear controversy. The integration of different perspectives enables to pinpoint several key aspects of the austrian nuclear controversy for the development of a broad rejection of nuclear technologies in the post-chernobyl era: the obligation to reach a consensus between the political parties, a specific set of ideas described as the imaginary of a ‘nuclear free Austria’ and its specific relations to national identity.

    2016-01-01

    Nuclear Energy Data is the Nuclear Energy Agency's annual compilation of statistics and country reports documenting nuclear power status in NEA member countries and in the OECD area. Information provided by governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies and fuel cycle developments, as well as projections of nuclear generating capacity and electricity production to 2035, where available. Total electricity generation at nuclear power plants and the share of electricity production from nuclear power plants increased slightly in 2015, by 0.2% and 0.1%, respectively. Two new units were connected to the grid in 2015, in Russia and Korea; two reactors returned to operation in Japan under the new regulatory regime; and seven reactors were officially shut down - five in Japan, one in Germany and one in the United Kingdom. Governments committed to having nuclear power in the energy mix advanced plans for developing or increasing nuclear generating capacity, with the preparation of new build projects progressing in Finland, Hungary, Turkey and the United Kingdom. Further details on these and other developments are provided in the publication's numerous tables, graphs and country reports. This publication contains 'Stat Links'. For each Stat Link, the reader will find a URL which leads to the corresponding spreadsheet. These links work in the same way as an Internet link. (authors)

  11. Nuclear energy

    1978-01-01

    2 1/2 years ago a consultation group was formed to help the Section for Social Questions of the Council of Churches in the Netherlands, to answer questions in the area of nuclear energy. During this time the character of the questions has changed considerably. In the beginning people spoke of fear and anxiety over the plans for the application of this new technical development but later this fear and anxiety turned to protest and opposition. This brochure has been produced to enlighten people and try and answer their alarm, by exploring the many facets of the problems. Some of these problems are already being deeply discussed by the public, others play no role in the forming of public opinion. The points of view of the churches over nuclear energy are not expressed, the brochure endeavours to express that nuclear energy problems are a concern for the churches. Technical and economic information and the most important social questions are discussed. (C.F.)

    The world nuclear energy is on the upswing. This is shown by lifetime extensions up to 60 years and the construction of new nuclear power plants. Especially, the progressive climate change requires new, definitive, fast and decisive solutions. Europe has to find the right energy mix for the future having the magic triangle of environmental sustainability, security of supply and economic affordability in mind. At the centre of all the efforts made by many countries all over the world, nuclear is one vital key technology to face and combat global warming. Nuclear has a positive eco-balance, nuclear gives security of supply and nuclear power generation is competitive. Beside this the most important fact is and will be the high safety to run a nuclear power plant. The energy mix in the EU of the next decades will be defined today. It is vital to consider every option, which can contribute to a sustainable energy mix. Nuclear alone is not the solution for all problems but there will be no sustainable solution without nuclear.

    Innovation has been a driving force for the success of nuclear energy and remains essential for its sustainable future. Many research and development programmes focus on enhancing the performance of power plants in operation, current fuel design and characteristics, and fuel cycle processes used in existing facilities. Generally performed under the leadership of the industry. Some innovation programmes focus on evolutionary reactors and fuel cycles, derived from systems of the current generation. Such programmes aim at achieving significant improvements, in the field of economics or resource management for example, in the medium term. Often, they are undertaken by the industry with some governmental support as they require basic research together with technological development and adaptation. Finally, large programmes, often undertaken in an international, intergovernmental framework are devoted to design and development of a new generation of systems meeting the goals of sustainable development in the long term. Driving forces for nuclear innovation vary depending on the target technology, the national framework and the international context surrounding the research programme. However, all driving factors can be grouped in three categories: market drivers, political drivers and technology drivers. Globally, innovation in the nuclear energy sector is a success story but is a lengthy process that requires careful planning and adequate funding to produce successful outcomes

    Tightly coupled nuclear-renewable hybrid energy systems (N-R HESs) are an option that can generate zero-carbon, dispatchable electricity and provide zero-carbon energy for industrial processes at a lower cost than alternatives. N-R HESs are defined as systems that are managed by a single entity and link a nuclear reactor that generates heat, a thermal power cycle for heat to electricity conversion, at least one renewable energy source, and an industrial process that uses thermal and/or electrical energy. This report provides results of an analysis of two N-R HES scenarios. The first is a Texas-synthetic gasoline scenario that includes four subsystems: a nuclear reactor, thermal power cycle, wind power plant, and synthetic gasoline production technology. The second is an Arizona-desalination scenario with its four subsystems a nuclear reactor, thermal power cycle, solar photovoltaics, and a desalination plant. The analysis focuses on the economics of the N-R HESs and how they compare to other options, including configurations without all the subsystems in each N-R HES and alternatives where the energy is provided by natural gas.

  18. Man, environment and nuclear energy

    International Nuclear Information System (INIS)

    Gardan, Jacques.

    1978-10-01

    The acceptability of nuclear fission as energy source is governed by three factors, economic, ecological and sociological. It is necessary to account first for the economic context and for the state of natural resources: gradual exhaustion of fossil fuels as a result of ever-increasing demands. The biological risk concept which determines the acceptable industrial application level is the second factor to be considered. The danger of radioactive contamination is almost inexistent except in the accident hypothesis, and power stations are built with excessive safeguards against hypothetical accidents. The idea of systematic processing of all working effluent to reduce radioactive waste discharge by several orders of magnitude (zero release principle) is being examined. At present, the waste discharge levels are always well below the limits set by the CIPR and present no danger to the population. The only serious problems seem to be the disposal of radioactive wastes and the plutonium non-proliferation question bound up with breeder reactors. Whereas vitrification, the new 'Synroc' process, offer some solution to the radioactive waste conditioning problem, responsibility for the proliferation of nuclear weapons rests with the human conscience alone. The development of nuclear power stations over several decades seems to present no inacceptable danger and offers the best compromise between growth and minimum risk requirements. The third factor to be accounted for is the opposition displayed by a fraction of the population to the development of nuclear energy for peaceful applications [fr

    The soundness of use of nuclear energy in electric energy generation has received public concern due to the public highly exaggerated fear of nuclear power. It is the purpose of this paper to clear up some issues of public misunderstanding of nuclear power. Those of most importance are the unjustified fears about safety of nuclear power plants and the misunderstanding of nuclear risks and fears of nuclear power plants environmental impact. The paper is addressed to the public and aims at clarifying these issues in simple, correct, and convincing terms in such a way that links the gap between the scientists of nuclear energy and the general public; this gap which the media has failed to cover and failed to convey honestly and correctly the scientific facts about nuclear energy from the scientists standards to the public

    Nuclear energy in Thailand can be highlighted when the Office of Atomic Energy for Peace (OAEP) was established since 1961 for taking role of nuclear safety regulation, conducting research and promotion for peaceful uses of nuclear energy. Its main facilities were the 1 megawatt Thai Research Reactor-1 (TRR-1) and the Cobalt-60 Gamma Irradiator. Since then there have been substantial progress made on utilization of nuclear energy in various institutions and in private sectors. Nowaday, there are around 500 units of nuclear energy users in Thailand, i.e. 100 units in medicine, 150 units in education and 250 units in industry. In terms of nuclear power for electricity generation, the Electricity Generating Authority of Thailand (EGAT) has conducted the activities to support the nuclear power plant project since 1972 however, because there is widespread public concerned about nuclear safety, waste disposal and recently economic problems in Thailand, nuclear energy option is not put in immediate plan for alternative energy resource. Within the short future, increased in economical, demand fir electricity and safe operation of nuclear plants will likely be demonstrated and recognized. Nuclear energy should remain as an option in the long-term energy strategies for Thailand. (author)

    1978-01-01

    Nuclear power stations are the large scale compound system composed of many process systems. Accordingly, for the safe and high reliability operation of the plants, it is necessary to grasp the conditions of respective processes exactly and control the operation correctly. For this purpose, the process instrumentation undertakes the important function to monitor the plant operation. Hitachi Ltd. has exerted ceaseless efforts since long before to establish the basic technology for the process instrumentation in nuclear power stations, to develop and improve hardwares of high reliability, and to establish the quality control system. As for the features of the process instrumentation in nuclear power stations, the enormous quantity of measurement, the diversity of measured variables, the remote measurement and monitoring method, and the ensuring of high reliability are enumerated. Also the hardwares must withstand earthquakes, loss of coolant accidents, radiations, leaks and fires. Hitachi Unitrol Sigma Series is the measurement system which is suitable to the general process instrumentation in nuclear power stations, and satisfies sufficiently the basic requirements described above. It has various features as the nuclear energy system, such as high reliability by the use of ICs, the methods of calculation and transmission considering signal linkage, loop controller system and small size. HIACS-1000 Series is the analog controller of high reliability for water control. (Kako, I.)

    In spite of the easing of worldwide energy supply and demand situation in these years, we believe that research efforts towards the next generation nuclear energy are indispensably necessary. Firstly, the nuclear colleagues believe that nuclear energy is the best major energy source from many points of view including the global environmental viewpoint. Secondly, in the medium- and long-range view, there will once again be a high possibility of a tight supply and demand situation for oil. Thirdly, nuclear energy is the key energy source to overcome the vulnerability of the energy supply structure in industrialized countries like Japan where virtually no fossil energy source exists. In this situation, nuclear energy is a sort of quasi-domestic energy as a technology-intensive energy. Fourthly, the intensive efforts to develop the nuclear technology in the next generation will give rise to a further evolution in science and technology in the future. A few examples of medium- and long-range goals of the nuclear energy research are development of new types of reactors which can meet various needs of energy more flexibly and reliably than the existing reactors, fundamental and ultimate solution of the radioactive waste problems, creation and development of new types of energy production systems which are to come beyond the fusion, new development in the biological risk assessment of the radiation effects and so on. In order to accomplish those goals it is quite important to introduce innovations in such underlying technologies as materials control in more microscopic manners, photon and particle beam techniques, accelerator engineering, artificial intelligence, and so on. 32 refs, 2 figs

  6. Nuclear energy and international cooperation

    There is no need to emphasize that nuclear energy cannot be developed without international cooperation at either the industrial or the academic level. In the meanwhile, there have been some marked political, economic and social changes in recent years which are posing constraints to the international cooperation in nuclear energy. The problems and constraints impeding nuclear power programs cannot be overcome by only one nation; international cooperation with common efforts to solve the problems is essential. Nuclear energy is different from fossil energy resources in that it is highly technology-intensive while others are resource-intensive. International cooperation in technology has an entirely different importance in the field of nuclear energy. Educational institutions will play a role in a new era of the international cooperation.

  7. Nuclear energy synergetics and molten-salt technology

    1988-01-01

    There are various problems with nuclear energy techniques in terms of resources, safety, environmental effects, nuclear proliferation, reactor size reduction and overall economics. To overcome these problems, future studies should be focused on utilization of thorium resources, separation of multiplication process and power generation process, and application of liquid nuclear fuel. These studies will lead to the development of molten thorium salt nuclear synergetics. The most likely candidate for working medium is Lif-BeF 2 material (flibe). 233 U production facilities are required for the completion of the Th cycle. For this, three ideas have been proposed: accelerator M.S. breeder, impact fusion MSB and inertial conf. fusion hybrid MSB. The first step toward the development of molten Th salt nuclear energy synergetics will be the construction of a pilot plant of an extreme small size. As candidate reactor, the author has selected mini FUJI-II (7.0 MWe), an extremely small molten salt power reactor. Mini FUJI-II facilities are expected to be developed in 7 - 8 years. For the next step (demonstration step), the designing of a small power reactor (FUJI 160 MWe) has already been carried out. A small molten salt reactor will have good safety characteristics in terms of chemistry, material, structure, nuclear safety and design basis accidents. Such reactors will also have favorable economic aspects. (Nogami, K.)

    After having briefly outlined that introducing a relationship between geography and nuclear energy is a quite recent approach, and by often quoting a researcher (Teva Meyer) specialised in Swedish energy issues, the author briefly discusses how nuclear energy structures territories through meshing and 'polarisation' effects, and economic and social impacts. He also discusses whether territories then become dependent on nuclear activity, what happens when a nuclear plant stops, how the existence of a nuclear plant becomes an identity market for a territory, and how material flows also deal with geography. In the last part, the author notices that in Germany, nuclear industry is considered as an industry like any other one. He finally outlines that geography could be useful to achieve energy transition

    Last November - almost in parallel with the Hague Meeting on Climate Change - more than 1,500 of the world's top nuclear scientists and energy technologists met in Washington DC, at the Joint Conference of the American Nuclear Society, the European Nuclear Society, the Nuclear Energy Institute and the International Nuclear Energy Academy. Unlike the United Nations follow up to the Kyoto protocol, which ended in disarray, a note of high optimism and informed realism pervaded the nuclear conference which, among its multiple streams of subject material and papers by international experts, carried the two main themes of Long Term Globally Sustainable Energy Options and Nuclear Energy and the Greenhouse Problem. This paper considers the immense contribution to Greenhouse gas emission minimisation made by nuclear energy in 1999. In that year the global electricity production by the world's 435 nuclear power stations was 2,398 TWh or 16% of total electricity generation or 5% of total primary energy production. The amount of avoided carbon dioxide emission because of the use of nuclear energy in 1999 was 2.4 billion tonnes. This is 10% of total emissions. Japan's 54 nuclear power stations alone save the equivalent of Australia's total Greenhouse emissions. The secret of this success is Australia's uranium fuel

    Energy planning development is a part of the sustainable development that supports the attainment of national development goals. The objective of the study is to support the national planning and decision-making process in the energy and electric sector in Indonesia with nuclear option for period of 1997- 2027. This study performs the provision of detailed economic sector and regional energy demand projection by MAED simulation model based on the economic and population scenarios. Then continued with the optimization of the future energy supply such as electricity supply taking all known Indonesian energy sources and all relevant technologies into consideration by MARKAL Model. The result shows that Indonesia's need for final energy is forecasted to increase two times, from 4,028.4 PJ at the beginning of study become 8,145.6 PJ at the end of study. The more the use of fossil fuels are tightened and enforced because of its environmental impact, the earlier the nuclear power becomes part of the optimum generation mix. In the case IEA1001 (reduction of 1% CO 2 emission), nuclear energy is needed in Jawa-Bali region in the earliest possibility i.e. year 2018 corresponding to 0.37 GW and it will increase in the next years

  12. Nuclear energy and social impact

    2010-01-01

    Economic development and population increase are boosting a new process of energy demand all around the world which implies also a protection of the environment and, consequently, the reduction of emissions of CO 2 , a challenge that has to be solved. Fossil fuels represent the cheapest costs in capital and have as common features that their exploitation is based on largely known technologies, having developed a big experience in construction, operation and maintenance. However they are big environment polluters. Nuclear energy fulfils three of the main objectives that should be pursued for a steady development: 1. It does not emit Greenhouse gases. 2. It is the cheapest produced energy. 3. It guarantees a security in its supply due to the fact, among others, that it is not conditioned by external factors. However, as any other energy source, nuclear power has its own drawbacks. Some are real and some are fictitious. For this reason it becomes necessary to improve the social image of this source of energy, so as to counteract the negative consequences of the antinuclear discourse, promoted late in the seventies that has permanently undermined public acceptance

    Prospects increase, that with a controlled process of nuclear fusion one day an additional nuclear energy source will be commercially exploitable. In what follows, scientific principles according to the most recent research will be presented. Since approximately 30 years we are aware of the fact, that energy in form of light and heat provided by the sun and other fixed stars since over four billions years resulted from reactions of atomic nuclei. A series of such reactions became known which are considered for 'thermonuclear' processes, for example the carbon cycle by Bethe, where hydrogen is converted into helium. Most of the reflections and experiments dealt until 1938 with the reaction between nuclei of light elements. The possibility of splitting heavy nuclei was not anticipated. Its discovery by Hahn and Strassmann was a complete surprise - so to speak a rash reaction to release energy at the end of the element row. This 'way out' captured the interest of nuclear physicist for more than a decade. Only today, by starting to construct big nuclear power plants - only today, being able to assess the possibilities and limitations of this technology, the idea of energy generation through nuclear fusion steps into the foreground of nuclear research.

  14. Towards a nuclear energy technology roadmap. A new service to the nuclear community

    2005-01-01

    The role of nuclear energy in a future sustainable energy mix has been the subject of debates over the past few years. The future for nuclear energy will not only depend on this energy market development and the socio-political environment, but also on the innovation potential of the nuclear community to cope with the ever shorter business cycles in the energy market and the inherently longer term horizon needed in developing nuclear energy at its potential. Today's nuclear R and D community is in a transition phase, i.e. from former 'national' R and D-organisational structure to a truly international research area based on partnerships between organisations and companies creating networks-of-excellence. Several studies in the recent past have indicated the need for a shared vision in guiding this process. Identification of shared R and D-programmes, mergers and acquisitions of organizations and companies, knowledge gap analysis and the strategic mapping for each organization or company active in this nuclear R and D community. Technology Roadmapping is the appropriate tool to respond to these needs. Several stand-alone nuclear roadmap activities have been undertaken but lacked the possibility to analyse and make use of the synergies and interactions inherent to this technology development. The development has started of a master nuclear roadmap portal covering all the roadmap and technology foresight information in one so-called master nuclear roadmap. This master nuclear roadmap is implemented in an electronic online format allowing easy access, easy updating and lots of functionalities which may not be offered by traditional snap-shot roadmap reports. The paper will bring an overview on the role that technology roadmapping is playing in various industry sectors and the added value it may bring in the nuclear technology sector on a organizational as well as technology sector level. The paper will highlight the current status of this new initiative. (author)

  15. Nuclear and energy policy in Korea. Unchanging illusion of nuclear energy and citizens' challenge

    Korea is the tenth largest energy consumer in the world; the country ranks sixth in oil consumption, seventh in electricity consumption, and ninth in total CO2 emission. Korea now has 20 reactors in operation, nuclear power producing about 40% of its electricity. Its generating capacity from nuclear power plants is the sixth largest in the world; Korea currently exports nuclear technology. The rapid growth of this industry is attributed to extensive subsidy and protection from the Korean government; supported by government-initiated programs a powerful interest group, which consists of nuclear industries, technocrats, and governmental organizations concerned with nuclear policy, now exerts a major influence upon Korea's energy policy for nuclear expansion. Korea's nuclear power policymakers have, however, met opposition since End of the 1980s. The government's attempt to build a nuclear waste repository has provoked strong resistance from environmental movements and local citizens. Even if the government recently succeeded in designating Kyoungju as the nuclear waste site, the nuclear waste issue has awakened public interest in nuclear problems and strengthening public denunciation of Korea's expansive nuclear power policy. In addition, the activation of the Kyoto Protocol in February 2005 has impelled the government to redirect its energy policy towards a sustainable direction. This article focuses on the status and perspectives of Korea's nuclear power policy, enabling a discussion of the degree to which Korea's nuclear and energy policy has changed yet in many ways remains unchanged.

    Non-fission energy inputs to nuclear fuel cycles were calculated for four types of power reactors and for two grades of uranium ore. Inputs included all requirements for process operations, materials, and facility construction. Process stages are mining, milling, uranium conversion, enrichment, fuel fabrication, reprocessing, waste disposal, reactor construction and operation, and all transportation. Principal inputs were analyzed explicitly; small contributions and facility construction were obtained from input-output tables. For major facilities, the latter approach was based on disaggregated descriptions. Enrichment energy was that of U.S. diffusion plants, with uranium tails assay retained as a variable parameter. Supplemental electrical requirements, as a percentage of lifetime electrical output, are 5-6% for LWRs (0.3 - 0.2% tails assay) using ores with 0.2% uranium and without recycle. Recycle of uranium and plutonium reduces the electrical requirements 30%. Chattanooga Shales (0.006% U) require one-third more electricity. Thermal energy requirements are about 5% of electrical output with conventional ores; shales raise this to about 14%, with 0.2% enrichment tails and full recycle. About one-tenth of the electrical supplements and about a third of the thermal energy supplements are required prior to operation. A typical LWR will repay its energy loan within 15 months, allowing for low initial load factors. Enrichment requiring only 10% as much separative work as gaseous diffusion would reduce electrical requirements about 80%, but have little effect on thermal energy inputs. HTGRs require slightly less supplemental energy than LWRs. HWRs (with natural uranium) require about one-third as much supplemental electricity, but half again as much thermal energy, largely for heavy water production. The paper presents detailed data for several combinations of reactor type, ore grade and tails assay and compares them with conventional power plants. It also exhibits

    Due to rising energy costs and climate concerns, nuclear energy is again being seriously considered as an energy source for several countries. Along with the resurgence of nuclear energy comes the concern of the world if these countries will develop their programs for the peaceful use of nuclear energy. If on one hand the growth potential of nuclear energy should not be stifled, on the other hand it is imperative that a climate of mutual trust is developed, respecting the right of each country to develop its nuclear program without taking a climate of mistrust to a possible 'intention' behind the pursuit of peaceful use of nuclear energy. Therefore, it is essential that appropriate mechanisms of accountability of global governance are institutionalized at the institutional architecture of the international process of nuclear safeguards, more specifically to the nuclear fuel cycle, so that abuses of power in this sphere does not happen, both by countries that aspire to develop projects nuclear, and by the suppliers of technology. In this context, the case study of Brazil and Argentina gained importance, because these two countries have a single binational organization of nuclear safeguards in the world: Brazilian-Argentine Agency for Accounting and Control of Nuclear Materials - ABACC. In the theoretical question, the paper tries to understand what happens with the process of legitimacy and authority of the organizations of global governance by analyzing the degree of publicness and constrictiveness. This work intends to focus on the role of ABACC as an interstate institution of accountability, which has a key role to control the nation States of Brazil and Argentina regarding the appropriate use of nuclear material used in their programs, and analyze how this Agency behaves within of tension legitimacy-authority, taking into account existing studies on accountability in global governance.

    1994-01-01

    Nuclear energy plays a major role in the French economy because of the lack of fossil fuels on the French territory. About 75% of the French electric power is of nuclear origin. This paper gives an analysis of the French public attitude about nuclear energy and the methods used by the nuclear industrialists to better the electro-nuclear image. Communication, advertising and transparency are the best attitudes for a suitable public information and are necessary to reduce the public anxiety after the Chernobyl accident. Television advertising, magazines and organized visits of nuclear installations have allowed to explain the interest of nuclear energy in the environmental reduction of pollutants. However, public information must include the topic about nuclear wastes to remain credible. (J.S.)

    The current promising base for massive hydrogen production on high temperature environment derives primarily from three sources: the commercial production of chemicals for the sulfur-iodine (SI) process, the development of solid-oxide fuel cells (SOFC), and the hybrid method of chemicals and fuel cells. The three kinds of process requires high temperature heat energy over 850∼950 .deg. C for the efficient and economic hydrogen production. One of the clean, economic, and moreover promising heat sources supplied to the process is nuclear plants. The nuclear plants producing high temperature heat energy over 950 .deg. C are well known as Very High Temperature Reactors (VHTR) which could have two types of prismatic and pebble-bed cores along reactor core shape. In this paper, we report on the Hybrid Sulfur Process (HyS), and the estimated costs for the system which composes of VHTR of prismatic core type and HyS plant. Nuclear hydrogen production system based on HyS process has been configured to optimally use the thermal energy from VHTR and electric energy to produce hydrogen and oxygen from clean water. High temperature thermal energy is transferred to the HyS process by way of intermediate heat exchanger (IHX) with associated piping. In this paper, the hydrogen production costs for a system composed of a VHTR with six 600MWth module, a power conversion unit (PCU) and a HyS plant are presented, where the thermal energy produced in two module was converted to electric energy in PCU and then transferred to the electrolysis cells for hydrogen production and circulating units on HyS plant, and the remaining thermal energy was supplied to chemical process on HyS plants. As a preliminary study of cost estimates for nuclear hydrogen systems, the hydrogen production costs of the nuclear energy sources benchmarking GT-MHR are estimated in the necessary input data on a Korean specific basis. G4- ECONS was appropriately modified to calculate the cost for hydrogen production

    With reference to the public discussion which is taking place at the moment concerning the future of nuclear energy in the UK, the document from the Advisory Council on Research and Development for Fuel and Power and also the report of the Royal Commission on Environmental Pollution are considered. Although there have been many other projections of UK and world energy requirements prepared by many different organisations, few cover such a wide range of scenarios in such detail as the ACORD report. The Royal Commission report contains many reassuring findings on the more extreme claims of the worldwide anti-nuclear movement, but one cannot read it without gaining the impression that the nuclear option is the energy source they would most like to do without. It is felt that against this background, it would seem to be time for the power industry to stop defending nuclear energy as an acceptable necessity and rather promoting it as the best energy option.

    2018-05-01

    There is a significant amount of highly radiotoxic long-life nuclear waste (NW) produced by NPP (Nuclear Power Plants). Transmutation is a process which transforms NW into less radiotoxic nuclides with a shorter period of half-life by spallation neutrons or radiative capture of neutrons produced by ADS (Accelerator Driven System). In the processes of transmutation new radioactive nuclides are produced. ADS is big energy consumer equipment. It is a method for production of a high-flux and high-energy neutron field. All these processes occur in ADS simultaneously. ADS is able to transmute actinides and produce energy simultaneously. The article considers the energy production problems in ADS. Several ideas are developed regarding the solution of the global energy supply.

    Since the very beginning of its brief history, nuclear energy was doomed to public attention - because of its first application. For 50 years of existence it failed to become one of traditional energy technologies, which the society would assess on the basis of its actual advantages (such as energy efficiency, resource availability and environmental acceptability). Nuclear weapons and crisis of confidence resulting from severe accidents have both formed the attitude to nuclear. This paper considers the basic antinuclear arguments, such as proliferation, waste and severe accidents. The current status of relations between nuclear energy and the public is still close (not only in Russia, but also in almost all European countries) to this state of politicization of nuclear and constant irrational fear radiation causes among people. Nevertheless, the positive trend in the attitude towards nuclear energy is obvious, both in Russia and in the world. In 2006, the long-expected 'new nuclear energy policy' (with returned budgetary financing of the new nuclear build) was announced in Russia at the highest governmental level. After that the worldwide recognition of the need to develop nuclear energy was only growing. The scale of global energy development is so large that all sources capable of making a contribution will find their demand. In the same time, public opinion in the world inseparably connects the issue of energy security with measures to combat climate changes. The '2 deg. C problem', if solvable at all, could be addressed only by simultaneous implementation of all possible emission reduction measures (including carbon-free energy technologies) on an unprecedented scale. Emission-free nuclear energy can actually become a system capable of sustainable and prompt development. This paper considers the issues, which could hamper nuclear development and negatively impact the public attitude towards nuclear. (authors)

    As its operating role, its economic competitiveness and its technological control in the area of nuclear energy, the France has certainly to take initiatives in a nuclear renewal activity. The France is criticized in the world for its exclusive position about nuclear energy, but it is well situated to attract attention on the coal risks and particularly about its combustion for environment.

    As petroleum-based fuels grow increasingly scarce and costly, nuclear energy may become an important alternative source of industrial energy. Initial applications would most likely include a mix of fossil-fired and nuclear sources of process energy. A means for determining the overall reliability of these mixed systems is a fundamental aspect of demonstrating their feasibility to potential industrial users. Reliability data from nuclear and fossil-fired plants are presented, and several methods of applying these data for calculating the reliability of reasonably complex industrial energy supply systems are given. Reliability estimates made under a number of simplifying assumptions indicate that multiple nuclear units or a combination of nuclear and fossil-fired plants could provide adequate reliability to meet industrial requirements for continuity of service

    The NPP can either be used to produce electricity, or as heat source for non-electric applications (cogeneration). High Temperature Reactor (HTR) with high outlet coolant temperature around 900~1000 o C, is a reactor type potential for cogeneration purposes such as hydrogen production and other chemical industry processes that need high heat. Considering the national energy policy that a balanced arrangement of renewable and unrenewable natural resources has to be made to keep environmental conservation for the sake of society prosperity in the future, hydrogen gas production using nuclear heat is an appropriate choice. Hydrogen gas is a new energy which is environmentally friendly that it is a prospecting alternative energy source in the future. Within the study, a comparison of three processes of hydrogen gas production covering electrolysis, steam reforming and sulfur-iodine cycle, have been conducted. The parameters that considered are the production cost, capital cost and energy cost, technological status, the independence of fossil fuel, the environmental friendly aspect, as well as the efficiency and the independence of corrosion-resistance material. The study result showed that hydrogen gas production by steam reforming is a better process compared to electrolysis and sulfur-iodine process. Therefore, steam reforming process can be a good choice for hydrogen gas production using nuclear energy in Indonesia. (author)

  1. Present state of the perception gap of nuclear energy between Japanese nuclear energy supplying region and an energy consuming region

    Public opinion surveys have been carried out since 1998 on what phase and on what extent of the perception of nuclear energy differs between Japanese dwelling in energy supplying region and an energy-consuming region. Southern Fukui rural district where 15 nuclear reactors are now installed and Osaka urban region of about 100 km apart from Fukui were selected as the respective targets for the energy supplying and consuming regions. Analyses of the data of about 3000 samples have revealed the followings. (1) The public in the nuclear energy supplying region are very friendly to nuclear energy so that only about 20 and 39 of the public are resistive to the general promotion of nuclear energy in Japan and to the construction of another nuclear reactor in their dwelling region, respectively. (2) On the other hand, in the energy-consuming region those respective fractions are 41 and 70 implying strong resistance to nuclear energy in the urban region. (3) Both the degree of interest in and the degree of knowledge on nuclear energy are very low, whereas the extent of fear to nuclear is high for the urban public. (4) Not only the fraction of the public who are satisfied with their present life, but the public fraction who is eagerly support the thought of return-to-nature are very high in the urban region. (5) On the other hand, in the energy supplying region, many peoples eagerly want their life to become more convenient than it is now, and 6) all those trends (I)-(5) are revealed more pronouncedly in the woman than the man. The perception gap of nuclear energy thus became clear between Japanese dwelling in rural and urban regions. On the basis of this knowledge, discussions on the nature of the so-called NIMBY will be made from the socio-psychological viewpoint and propositions will also be made on the methods to dissolve the perception gap of that soft.

    This paper summarizes the key points of a report titled Nuclear Energy Outlook, published in 2008 by the Nuclear Energy Agency of the Organization for Economic Cooperation and Development, which has 30 member nations. The report discusses the commitment of many nations to increase nuclear power generating capacity and the potential rate of building new electricity-generating nuclear plants by 2030 to 2050. The resulting decrease in carbon dioxide emissions from fossil fuel combustion resulting from an increase in nuclear power sources is described. Other topics that are discussed include the need to develop non-proliferative nuclear fuels, the importance of developing geological disposal facilities or reprocessing capabilities for spent nuclear fuel and high-level radioactive waste materials, and the requirements for a larger nuclear workforce and greater cost competitiveness for nuclear power generation.

    Nuclear power currently produces over 628 M tep of the generated energy in 1997 avoiding about 1978 Mt of CO 2 emission and gives a significant contribution to reducing greenhouse gas emission. The competitive position of nuclear power might be strengthened, if market forces or government policy were able to give energy security and to control greenhouse gas, relying upon market mechanism and including environmental costs in economic analysis. In this case, taking into account the entire up-stream and down-stream chains for electricity generation, it can be seen that the greenhouse emission from nuclear plants, is lower than that of renewable energy chains. This paper investigates the potential role of nuclear power in global energy supply up to 2020 and analyzes the opportunities and the challenges for research, governments and nuclear industries of a broad nuclear power development in response to environmental concerns. The authors think that nuclear energy will have to compete in the same framework and under the same conditions as all other energy sources and so analyze the possibility of re-launching nuclear energy: it will have to couple nuclear safety and economic competitiveness [it

    Stainless steel has been used as important material in nuclear reactor and also in non nuclear industries. Nuclear data processing for generation of composite mixture cross-sections from several nuclides have been made. Provided evaluated nuclear data file (ENDF) such as ENDF/B- VI.8, JEFF-3.1 and JENDL-3.3 files were employed. Raw nuclear data cross-sections on file ENDF should be prepared and processed before it used in calculation. Sequence of nuclear data processing for generation of mixture cross-sections data from several nuclides is started from LINEAR, RECENT, SIGMA1 and MIXER codes taken from PREPR02000 utility code. Nuclear data processing is started from linearization of nuclear cross-sections data by using LINEAR code and counting background contribution of resonance parameter (MF2) with RECENT code (0 K) at energy ranges from 10 -5 to 10 7 eV. Afterward, the neutron cross-sections data should be processed and broadened to desire temperature (300 K) by using SIGMA1 code. Consistency of each cross-sections which used in nuclear data processing is checked and verified using FIXUP code. The next step is to define the composite mixture density (gr/cm 3 ) of stainless steel SUS-310 and weight fraction of each nuclide composition prior used it in MIXER code. All of the stainless steel SUS-310 cross sections are condensed to 650 energy groups structure (TART-energy structure) by using GROUPIE code to evaluate, analysis and review it more easily. The total, elastic scattering, non-elastic scattering and capture cross- sections of stainless steel SUS-310 have been made of ENDF/B-VI.8, JEFF-3.1 and JENDL-3.3 files. The stainless steel cross-sections made of ENDF/B- VI.8 file was taken as reference during validation process. The validation result of total cross-sections for stainless steel SUS-310 is clearly observed that the differences of total cross-sections error in nuclear data processing is relatively low than 0.01%.

    Energy demand in the world is growing increasingly, among other factors due to economic development. Every way of producing electricity has got their own drawbacks and has implicit environmental impact. Among all the energy sources, nuclear energy is the most polemic because of the way it is presented by the mass media. This aspect provokes controversy to occidental societies which reject this kind of energy with arguments normally based on a wrong and insufficient knowledge of the matter. The antinuclear discourse, promoted late in the seventies, has gone deeply into the collective social unconscious and has undermined public acceptance of nuclear energy due to the fact, deeply exploited by antinuclear groups, of linking nuclear energy with the atomic bombing of Hiroshima and Nagasaki. In this sense, it is important to mention that in Japan there was a profound resentment and opposition to nuclear energy, because the memory of the nuclear bombings was permanently alive. However when the Japanese government told its people that this energy was necessary to boost their industrial development, Japanese citizens in an unprecedented attitude of patriotism overcame their most antagonist feelings, in order to contribute to the industrial development of their country. The result was that most of them voted in favour. Presently Japan gets 30% of its energy by means of 56 nuclear power plants and 1 more is under construction. Antinuclear groups took as their best emblem the accident of Chernobyl to justify their opposition to the nuclear power plants. The manipulation of this accident has been one of the most shameful in the nuclear history. It is widely known among the experts that the reactor used in Chernobyl was a type of military plutonium converter with a positive temperature reactivity coefficient, which made very dangerous its functioning. Any nuclear regulatory commission in democratic and responsible countries would have never authorized the use of this reactor

  7. Once-through hybrid sulfur process for nuclear hydrogen production

    Increasing concern about the global climate change spurs the development of low- or zero-carbon energy system. Nuclear hydrogen production by water electrolysis would be the one of the short-term solutions, but low efficiency and high production cost (high energy consumption) is the technical hurdle to be removed. In this paper the once-through sulfur process composed of the desulfurization and the water electrolysis systems is proposed. Electrode potential for the conventional water electrolysis (∼2.0 V) can be reduced significantly by the anode depolarization using sulfur dioxide: down to 0.6 V depending on the current density This depolarized electrolysis is the electrolysis step of the hybrid sulfur process originally proposed by the Westinghouse. However; recycling of sulfur dioxide requires a high temperature heat source and thus put another technical hurdle on the way to nuclear hydrogen production: the development of high temperature nuclear reactors and corresponding sulfuric acid decomposition system. By the once-through use of sulfur dioxide rather than the closed recycle, the hurdle can be removed. For the sulfur feed, the desulfurization system is integrated into the water electrolysis system. Fossil fuels include a few percent of sulfur by weight. During the refinement or energy conversion, most of the sulfur should be separated The separated sulfur can be fed to the water electrolysis system and the final product would be hydrogen and sulfuric acid, which is number one chemical in the world by volume. Lowered electrode potential and additional byproduct, the sulfuric acid, can provide economically affordable hydrogen. In this study, the once-through hybrid sulfur process for hydrogen production was proposed and the process was optimized considering energy consumption in electrolysis and sulfuric acid concentration. Economic feasibility of the proposed process was also discussed. Based on currently available experimental data for the electrode

    This is a comment on an article by Prof. Haerle a theologist, published earlier under the same heading, in which the use of nuclear energy is rejected for ethical reasons. The comment contents the claim mode by the first author that theologists, because they have general ethical competency, must needs have competency to decide on the fittest technique (of energy conversion) for satisfying, or potentially satisfying, the criteria of responsible action. Thus, an ethical comment on, for instance, nuclear energy is beyond the scope of the competency of the churches. One is only entitled as a private person to objecting to nuclear energy, not because of one's position in the church. (HSCH) [de

    1988-01-01

    The use of electromagnetic energy in food processing is reviewed with respect to food safety, nutritional quality, and organoleptic quality. The effects of nonionizing radiation sources such as microwave and radio-frequency energy and ionizing radiation sources, e.g. radioactive cobalt-60 and caesium-137, on the inactivation of microbes and nutrients are compared with those of conventional heating processes both in terms of their kinetic behavior and their mechanisms of interaction with foods. The kinetics of microwave and conventional thermal inactivation are considered for a generalized nth-order model based on time and temperature conditions. However, thermal inactivation effects are often modeled by 1 st-order kinetics. Microbial and nutrient inactivation by ionizing sources are considered for a 1 st-order model based on radiation dose. Both thermal and radiation resistance concepts are reviewed and some typical values of radiation resistance are given for sensitive vegetative bacterial cells, yeasts, and molds and for resistant bacterial spores and viruses. Nonionizing microwave energy sources are increasingly used in home and industrial food processing and are well-accepted by the American public. But, despite recent Food and Drug Administration approval of low and intermediate ionizing radiation dose levels for grains and other plant products and the fact that irradiated foods are sold in more than 20 countries of the world, public fears in the U.S. about nuclear energy may limit the role of ionizing radiation in food processing and preservation and may also limit the use of nuclear fuels as an alternate source of electrical energy.

  12. Religious organizations debate nuclear energy

    Dowell, T.

    1984-08-01

    This paper reviews the history of the religious debate on nuclear energy over the last thirty years. In the 1950s, religious statements recognized the peaceful uses of atomic energy as a blessing from God and called upon world leaders to promote its use. Nuclear energy programmes were launched in this decade. In the 1960s, there was still religious approval of nuclear energy, but questions about ethics arose. It was not until the 1970s, after the oil crisis, that serious questioning and criticism of nuclear energy emerged. This was particularly true in the United States, where the majority of statements originated - especially in 1979, the year of the Three Mile Island accident. Around this time, the World Council of Churches developed the concept of the just, participatory and sustainable society. The meaning and use of these terms in the nuclear energy debate is examined. This paper also compares the balanced debate of the World Council with the case against the plutonium economy prepared by the National Council of the Churches of Christ in the USA. Three religious statements from the 1980s are examined. A United Church of Canada resolution, critical of nuclear energy, is compared with a favourable report from the Methodist Church in England. Both use similar values: in one case, justice, participation and sustainability; in the other case, concern for others, participation and stewardship. There are not many Catholic statements on nuclear energy. One which is cautious and favourable is examined in detail. It is concluded that the use of concepts of justice, participation and sustainability (or their equivalents) has not clarified the nuclear debate

    Over two thirds of the population (68%) believe that nuclear energy is necessary to secure the supply of power. This is one of the results of a representative poll conducted by the Demoscopic Institute Allensbach on behalf of the Nuclear Energy Information Circle of the German Atom Forum. 78% of the population are of the opinion that the power supply is secure for the next 20 years. The significance of nuclear power in today's power supply is, however, grossly underestimated. For example 30% of respondents put the number of nuclear power plants in the Federal Republic at four at the most. Many more people than one year ago are now convinced of the environmental compatibility of nuclear power plants. The public debate on nuclear energy is generally judged critically by politicians, journalists and experts: factual and emotional. 54% of the population and 71% of politicians interviewed regard the question of nuclear energy utilisation as a predominantly political decision. Questioned was a representative sample of the population which included politicians, journalists, scientists and energy economists. The results, which were presented at a press conference in Bonn by the economist Renate Koecher, are reviewed. (orig.) [de

    Nuclear energy was born in World War II and it has grown within the regime of Cold War. When the Cold War came to the end around early 1990 s, we who have benefited by the development of nuclear energy must have been challenged with a new tide of civilization change. Although it has not been so much closely questioned since then, such a new movement, that was submerging, abruptly manifested on September 11, 2001. Then, many of us realized that global circumstances, especially concerned with security, must have actually changed with the reordering of the world basic structures. This paper describes on the thoughts to reveal the cause and background of the event on September 11 with the linkage to nuclear energy development, or nuclear civilization in pursuit of the future regime of nuclear in harmonization with the global society in 21st century.

    The Government's views on the development of nuclear energy are outlined. In this country, we continue to see some important advantages in maintaining nuclear power generation. It increases diversity, and so helps to maintain security of energy supply. It does not produce greenhouse gases or contribute to acid rain. But it is equally clear that nuclear costs must be brought under control whilst at the same time maintaining the high standards of safety and environmental protection which we have come to expect in the UK. The three main elements which the nuclear industry must address in the future are summarized. First the costs of nuclear generation must be reduced. Secondly, once the feasibility and costings of PWRs have been established consideration must be given to the choices for the future energy policy and thirdly new reactor designs should be standardized so the benefits of replication can be realised.

  16. Hydrogen economy and nuclear energy

    International Nuclear Information System (INIS)

    Knapp, V.

    2004-01-01

    Global energy outlooks based on present trends, such as WETO study, give little optimism about fulfilling Kyoto commitments in controlling CO2 emissions and avoiding unwanted climate consequences. Whilst the problem of radioactive waste has a prominence in public, in spite of already adequate technical solutions of safe storage for future hundreds and thousands of years, there s generally much less concern with influence of fossil fuels on global climate. In addition to electricity production, process heat and transportation are approximately equal contributors to CO2 emission. Fossil fuels in transportation present also a local pollution problem in congested regions. Backed by extensive R and D, hydrogen economy is seen as the solution, however, often without much thought where from the hydrogen in required very large quantities may come. With welcome contributions from alternative sources, nuclear energy is the only source of energy capable of producing hydrogen in very large amounts, without parallel production of CO2. Future high temperature reactors could do this most efficiently. In view of the fact that nuclear weapon proliferation is not under control, extrapolation from the present level of nuclear power to the future level required by serious attempts to reduce global CO2 emission is a matter of justified concern. Finding the sites for many hundreds of new reactors would, alone, be a formidable problem in developed regions with high population density. What is generally less well understood and not validated is that the production of nuclear hydrogen allows the required large increases of nuclear power without the accompanied increase of proliferation risks. Unlike electricity, hydrogen can be economically shipped or transported by pipelines to places very far from the place of production. Thus, nuclear production of hydrogen can be located and concentrated at few remote, controllable sites, far from the population centers and consumption regions. At such

    The contribution takes it that the assumption, acceptance problems of nuclear energy are based on information deficit, is groundless in the end. It is true that there is a big knowledge gap between the nuclear energy experts and the broad public, empirical investigations, however, point out that increased knowledge would by no means go along with increased nuclear energy acceptance in the population. Also, the interpretation pattern 'Science and technology hostility' is not good enough to explain the nuclear energy controversy, because nuclear energy opponents oppose nuclear energy in an increasingly professional manner, and as an alternative they do not propagate renunciation of technology but another kind of energy technology. The degree of intensity and the long duration of the nuclear energy controversy in the Federal Republic of Germany in international comparison is defined by 1. little willingness in the 'interest block' in state, industry and nuclear research in favour of speeding up nuclear energy expansion, to yield to the requirements of the anti-nuclear-energy movement, and 2. factual possibilities of the ecological movement, also without parliamentary majority, to hinder the nuclear energy program and, consequently, to influence political decisions. In addition, social peripheral conditions play a role. (orig./HSCH) [de

    For the second time since the start of commercial nuclear electricity generation, an accident has the world wondering if uranium will be among the future fuel choices in electricity production. Unfortunate when one considers the low-carbon footprint of this energy option. An accident involving a nuclear power plant, or more appropriately the perceived risks associated with an accident at a nuclear power plant, is but one of the issues that makes the impact assessment process related to nuclear energy projects challenging. Other aspects, including the time scales associated with their siting, licensing, operation and decommissioning, also contribute to the challenge. Strategic environmental assessments for future fuel choices in electricity generation, particularly ones that consider the use of life cycle assessment information, would allow for the effective evaluation of the issues identified above. But more importantly from an impact assessment perspective, provide for a comparative assertion for public disclosure on the environmental impacts of fuel choice. This would provide the public and government decision makers with a more complete view of the role nuclear energy may be able to play in mitigating the climate and carbon impacts of increased electricity production, and place issues of cost, complexity and scale in a more understandable context.

    The competitiveness of nuclear energy in relation to fuel oil is now fully established for electricity generation, not merely for base production but also for much lower load factors. Likewise, in the field of steam generation nuclear energy has a high competitivity margin in comparison with fuel oil. At the outlet of the boiler the cost of the nuclear steam B.T.U. is much lower than the cost of the nuclear electricity B.T.U., but this advantage could be evened out, partially or totally, by the ease of transportation and the flexibility of utilization of electricity. The availability of high temperatures may in the future open new markets (hydrogen production, industrial processes ..). Thus, through its various vectors, nuclear energy may occupy an important place in the energy balance of a country. An evaluation has been made, on certain assumptions, until the year 2030, of the place that nuclear energy will take. The evaluation shows clearly that uranium supply will be next to impossible if nuclear energy is supplied by light water reactors, associated or not with other thermal reactors. It will be necessary to resort urgently to fast breeder reactors. The acceleration of the fast breeder reactors breakthrough resulting from the insertion of natural uranium converters does not fundamentally change the supply problem, nor does the insertion of HTRs intended to break into the high temperature market. On the other hand, improvement of the performance of fast breeder reactors, particularly an increase in the breeding ratio and a shortening of the cycle, might have a decisive effect and might ensure the definite mastering of the uranium needs.

    The field of nuclear safeguards has received increasing amounts of public attention since the events of the Iraq-UN conflict over Kuwait, the dismantlement of the former Soviet Union, and more recently, the North Korean resistance to nuclear facility inspections by the International Atomic Energy Agency (IAEA). The role of nuclear safeguards in these and other events relating to the world's nuclear material inventory is to assure safekeeping of these materials and to verify the inventory and use of nuclear materials as reported by states that have signed the nuclear Nonproliferation Treaty throughout the world. Nuclear safeguards are measures prescribed by domestic and international regulatory bodies such as DOE, NRC, IAEA, and EURATOM and implemented by the nuclear facility or the regulatory body. These measures include destructive and non destructive analysis of product materials/process by-products for materials control and accountancy purposes, physical protection for domestic safeguards, and containment and surveillance for international safeguards

  5. Emerging nuclear energy systems and nuclear weapon proliferation

    Generally when considering problems of proliferation of nuclear weapons, discussions are focused on horizontal proliferation. However, the emerging nuclear energy systems currently have an impact mainly on vertical proliferation. The paper indicates that technologies connected with emerging nuclear energy systems, such as fusion reactors and accelerators, enhance the knowledge of thermonuclear weapon physics and will enable production of military useful nuclear materials (including some rare elements). At present such technologies are enhancing the arsenal of the nuclear weapon states. But one should not forget the future implications for horizontal proliferation of nuclear weapons as some of the techniques will in the near future be within the technological and economic capabilities of non-nuclear weapon states. Some of these systems are not under any international control. (orig.) [de

  6. Should we embrace nuclear energy?

    During his recent tour of North America, Australian Prime Minister John Howard called for a 'full-blooded debate' about the place of nuclear power in the nation's energy mix. 'I have a very open mind on the development of nuclear energy in my own country,' he said. Treasurer Peter Costello said that only economic arguments precluded Australia's move to nuclear energy. 'If it becomes commercial, we should have it,' he said on 23 May. But in reality the 'debate' had already been adjudicated. Three days later the Australian Nuclear Science and Technology Organisation (ANSTO) presented Science Minister Julie Bishop with a report that delivered Costello's economic justification for nuclear power

    In Chile, demand for electricity will soon exceed water resources. The country will then face severe energy dependence, with very little control over generation costs, and with increasing emission of contaminating gases into the atmosphere. Nuclear energy may be considered an appropriate and stabilizing alternative for the system in the medium term, the benefits of nuclear generation to be thus extended to a country which has a moderate demand for electricity. This new scenario will require an additional technical and regulating effort by CCHEN and by the state, as well as re-orientation of their activities in connection with public opinion. The Public Nuclear Energy Education Program, initiated in 1976 by CCHEN, has been developed for purposes of achieving public acceptance of nuclear energy as a way of facilitating development of various activities which pertain to CCHEN's scope of action, and of creating a climate which is favorable to acceptance of nuclear energy as an alternative source of energy. Thus, the object is that the public draw informed conclusions on the benefits and risks implicit in the use of isotopes, radiation, and nuclear power generation. The Program consists of activities for high school students aimed at vocational orientation of those who stand out in the science area, training and extension activities for teachers, journalists, and professionals, a program of guided tours of the nuclear centers, a publicity campaign conducted in the various media and, since 1980, massive distribution of brochures and magazines. There are no declared anti-nuclear movements in Chile. Nevertheless, there are opinions against nuclear power in different relevant sectors. Lately, the social communication media have preferred CCHEN as their source of information, a fact which makes it possible for the latter to have access to good coverage of its activities

  9. The role of nuclear energy in times of energy transition

    International Nuclear Information System (INIS)

    2012-01-01

    Since the reactor catastrophe in Fukushima, the risk of nuclear power has once again become more evident to the public and has also led to a rethinking of politics in Europe. Slogans like ''Nuclear Power, No Thanks!'', ''Get Out of Euratom'' are making more and more the rounds. The phase-out of nuclear energy is the topic that is increasingly provoking people to think. But how should one handle this? What role will nuclear energy play in a distant future? Central factors such as the economic viability of renewable energy sources and the environmental and social compatibility of production and distribution must be taken into account, while at the same time the reduction of pollutants and greenhouse gases must continue. If this is done without nuclear energy, is the rapid abandonment of nuclear energy even necessary or does nuclear energy generation have to be used as a temporary solution? (roessner)

    Finland currently generates about 40% of its electricity from nuclear power. This achievement of worldwide record magnitude is based on long-lasting efforts to build and maintain the competent infrastructure and close international cooperation required by this demanding technology. This booklet published by the Finnish Atomic Energy Commission gives an overview of nuclear energy and related organizations in Finland. It describes the utility companies and nuclear power production, the manufacturing industry and its export potential, research and educational activities and the legal framework and authorities for nuclear safety and administration. International cooperation has been essential for Finland in developing its nuclear energy capacity and appreciation is espressed to many countries and international organizations which have contributed to this. At the same time Finnish organizations are willing to share the experiences and know-how they have gained in building nuclear power in a small country. This is a road which will be followed by many other countries in the decades to come. It is hoped that this booklet will also help to open new channels of cooperation in such efforts

    An explanation is proposed for the nuclear reactions that occur in the electrolysis class of LENR processes. The proposed explanation postulates that a proton, or deuteron, dissolved in the hydrogen bearing metal cathode, absorbs its associated atomic electron to become a short lived state of the neutron with the resulting neutrino in a singular wave function centered on the neutron. The energy required to initiate this endothermic reaction is supplied either by the ion current during electrolysis type experiments, or by ion bombardment in plasma type experiments. It is the energy of this bombardment of the cathode with heavy ions that creates a coherent polyplasmon field within crystalline metallic grains that are present in the metal cathode of typical active electrolysis cells. The LENR process consists of a second order reaction mediated by a coherent plasmon field excited in the conduction electrons in a hydrogen bearing metal that is in the form of crystalline grains of the order of a few microns in dimension. The coherent plasmon field in each grain is called a polyplasmon. The metallic grains typically form during solidification of a metal, the impurities being forced to the grain surfaces. The resulting grain thus forms a resonant structure that can be filled with a number of coherent plasmons, i.e., a polyplasmon. Energy from the polyplasmon is coupled to the nucleus via electron capture by hydrogen. Because the neutrino has mass, its wave function has a second class of solutions. This description can take the form of a short lived pairing with the neutron that results from electron capture by the hydrogen nucleus. This short-lived compound particle is named the 'dion' and in the case of deuterium results in a 'dineutron'. Because the dion and dineutron are formed with essentially thermal kinetic energy, they can capture in nearby nuclei, either in hydrogen or in the host metal. Most of the resulting exothermic nuclear energy is

  15. France and Germany nuclear energy policies revisited: A veblenian appraisal

    2013-01-01

    Full Text Available Nuclear energy policy should have been a major area of cooperation for France and Germany, playing a lead role in the energy policy of the EU. Yet they have retained different options, especially regarding nuclear energy while the EU energy policy remained very indicative. These two “coordinated economies” should have been able to cooperate more closely on this issue. While the reasons for this difference in behavior have much to do with the specificities of the nuclear energy, they are more precisely related to the continuously rising level of security requirements, a learning process in which the magnitude of risks and time lengths appeared, even before Fukushima, to go beyond rational boundaries on which cooperation (as well as market ventures could be based. This raises the issue in the present state of the technologies of the possibility of an international governance of this nuclear industry.

  16. The situation of energy and nuclear energy in Switzerland

    1981-01-01

    The Swiss energy supply is one-sided and depends strongly on foreign countries. Therefore, the mineral oil share of about 70% and the import share of more than 80% should be decreased and substituted respectively. The electricity is one of the most important mineral oil alternatives. Today, this energy is produced at 30% in nuclear plants. For covering the moreover increasing demand of about 4%/year a 1000 MW nuclear power plant is under construction and two further plants are in advanced planning situation. The general conditions for the future extension of nuclear energy have been defined for 1979 in a supplement of the atomic law of 1959, approved by a plebiscite. Shortly before that event an initiative against nuclear energy was defeated. The statements are completed with some aspects of waste elimination, environment protection and economy of nuclear energy in Switzerland. (Auth.)

    In support of more efficient utilization of clean energy generation sources, including renewable and nuclear options, HES (hybrid energy systems) can be designed and operated as FER (flexible energy resources) to meet both electrical and thermal energy needs in the electric grid and industrial sectors. These conceptual systems could effectively and economically be utilized, for example, to manage the increasing levels of dynamic variability and uncertainty introduced by VER (variable energy resources) such as renewable sources (e.g., wind, solar), distributed energy resources, demand response schemes, and modern energy demands (e.g., electric vehicles) with their ever changing usage patterns. HES typically integrate multiple energy inputs (e.g., nuclear and renewable generation) and multiple energy outputs (e.g., electricity, gasoline, fresh water) using complementary energy conversion processes. This paper reports a dynamic analysis of two realistic HES including a nuclear reactor as the main baseload heat generator and to assess the local (e.g., HES owners) and system (e.g., the electric grid) benefits attainable by their application in scenarios with multiple commodity production and high renewable penetration. It is performed for regional cases – not generic examples – based on available resources, existing infrastructure, and markets within the selected regions. This study also briefly addresses the computational capabilities developed to conduct such analyses. - Highlights: • Hybrids including renewables can operate as dispatchable flexible energy resources. • Nuclear energy can address high variability and uncertainty in energy systems. • Nuclear hybrids can reliably provide grid services over various time horizons. • Nuclear energy can provide operating reserves and grid inertia under high renewables. • Nuclear hybrids can greatly reduce GHG emissions and support grid and industry needs.

    Nuclear Energy for New Europe - what does it mean? New Europe - it means in first order joined Europe. And it is quite clear that also efforts in nuclear energy must be joined. What can be proposed as a target of joint efforts. Improvement of existing plants, technologies, materials? - Certainly, but it is performed already by designers and industry themselves. There exists a problem, which each state using nuclear energy faces alone. It is nuclear waste problem. Nowadays nuclear waste problem is not completely solved in any country. It seems reasonable for joining Europe to join efforts in solving this problem. A satisfactory solution would reduce a risk connected with nuclear waste. In addition to final disposal problem solution it is necessary to reduce total amount of nuclear waste, that means: reducing the rates of accumulation of long-lived dangerous radionuclides; reducing the existing amounts of these radionuclides by transmutation. These conditions can be satisfied in reasonable time by burning of minor actinides and, if possible, by transmutation of long-lived fission products. However we can use this strategy effectively if we will design and construct nuclear energy as a system of which components are united by nuclear fuel cycle as a system-forming factor. The existing structures and approaches may become insufficient for new Europe. Therefore among the initial steps in considering nuclear waste problem must be considering possible promising fuel cycles for European nuclear energy. So, does new Europe need new nuclear energy? It seems, yes. (author)

    A research group at the Nuclear Research Centre, Julich, has attempted to trace public attitudes to nuclear power and their roots. The structure of attitudes, types of reasoning and the processes involved in deciding about nuclear power were measured. Intuitive perceptions of technology and risk were studied. Attitudes to nuclear energy are found to be the result of intuitive processes and opposition is 'natural' on the basis of intuitive reasoning. Many people who believe nuclear power to be hazardous nevertheless will accept it as inevitable for the economic advantages it will bring in the future. (U.K.)

    A great deal of energy will be needed for industrial development. The risks of energy production can be either individual or social in nature. Individual risk occurs in different places and different times to individuals in a certain period of time. Social risk occurs to several people in a time. People tend to refuse a nuclear power plant because of its social risk. This attitude is based more on feelings than reason. In fact radiation from a nuclear power plant is only 0.15% while radiation from medical instruments and from the environment is 99%. From the safety, pollution effect, price, and uses point of view, it can be concluded that nuclear energy is the most appropriate energy to face the future of the nation. (RUW)

    Basing on our present knowledge the following energy sources for energy supply must be taken into consideration in the long term: regenerative energy sources, fission energy gained by breeder reactors, nuclear fusion. While regenerative energy sources were treated at full length in the study 'Energy Sources for Tomorrow' the present study specifies the other two energy options. The availability and the reliability of nuclear primary energy carrier supply is described in detail and the conversion systems available or still being developed are investigated with regard to their specific consumption of primary energy. Topical questions concerning the proliferation stability of the fuel cycles and techniques are subject to the INFCE program. With reference to the nuclear energy documentation activities of the Federal Government this study is supposed to supply further fundamental material on nuclear primary energy carriers, consumption and readiness for application. Thus it will contribute to the question: 'Is nuclear energy an option which guarantees energy supply in the long term for the Federal Republic of Germany'. (orig.) 891 UA 892 ARA.

    2007-01-01

    In the course of the current discussion on promoting the economical competitiveness of sustainable energy systems, especially renewable and non-CO 2 -intensive ones, interest in nuclear energy has re-awakened in Europe (''nuclear renaissance''). This paper starts with presenting the concept of energy sustainability and its main elements. Next, an overview of the main results of sustainability assessments for different energy supply options (nuclear, fossil, renewables) covering full energy chains is given. Nuclear energy's typical strong and weak points are identified from a sustainability point of view. On the basis of these results, it is argued that more emphasis on nuclear energy's (very good) total cost performance, i.e. incl. externalities, rather than on its (very good) contribution to combating climate change would stronger benefit its ''renaissance''. Finally, the development of an overall EU-wide framework is proposed in order to assess the sustainability performance of alternative energy supply options, incl. nuclear, across their lifecycle and thus support decision making on developing sustainable energy mixes.

  6. Public attitudes to nuclear energy

    1984-09-01

    The last decade has seen a marked increase in public concern about nuclear energy. As a consequence, it is now recognized that the future of nuclear energy will not only depend on technical and economic factors, but that public acceptability of this technology will play a crucial role in its long-term future. This paper summarizes trends in public reactions to nuclear power in various countries and discusses a number of studies on public beliefs and attitudes to nuclear power in general, and to the building of a nuclear power plant near to one's home. It is concluded that the qualitative aspects of the possible risks of nuclear energy play an important role in the public's perception of this technology. It is also clear, however, that differences in perception of the risks do not embrace all the relevant aspects of the public's assessment of nuclear energy. Public reaction is also related to more-general beliefs and values, such as emphasis on economic versus social priorities, attitudes to technology and environmental concern. 11 references.

    The author states four points against nuclear power: 1. Although the probability of a catastrophic accident is very low, the consequences will be enormous. 2. Extension of the nuclear power generation worldwide will increase the danger of proliferation of nuclear weapons. 3. Decommissioning of nuclear power plants and disposal of nuclear waste will be a problem for many generations. 4. Protection of nuclear facilities may lead to the eventual abandonment of the civil rights assured by law. The author gives priority to energy conservation; he states that an 80% utilization factor is achievable in cogeneration and district heating. He agress with C.F. Weizsaecker on the long-term relevance of solar energy as the main energy source, which would also help to reduce the CO 2 problem (heat-up of the earth atmosphere, destruction of tropical forests). Energy supply without nuclear power plants would also provide new jobs, since there is no energy source as capital-intensive and low in staff requirements as nuclear power. (GL) [de

    The interest shown by the European Institutions in the energy debates, in which the nuclear energy is included as a key component within the energy mix, is obvious. Climate change and energy supply have pushed some countries to publicly express their interest for developing the nuclear energy. These positions are however in contradiction with some others within the European Union which are a lot more critical towards this type of energy and where face-out policies still prevail. Despite the fact that the use of the nuclear energy will remain within the competence of each Member State, the European Union will continue to play a prominent role in the development of an energy strategy based on a low carbon economy.

  12. Is nuclear energy power generation more dangerous than power generation by wind and solar energy

    1979-03-01

    Since the occurrence of the petroleum crisis, many countries have devoted a great deal of effort to search for substitute energy sources. Aside from nuclear energy, forms of power generation with wind, solar energy, and geothermal energy have all been actually adopted in one place or another. Most recently, a research report was published by the Canadian Bureau of Nuclear Energy Management stating that the use of wind and solar energy to generate electricity is much more dangerous than power generation with nuclear energy. When mining, transportation, machine manufacturing, etc. are included in the process of producing unit power, i.e. kilowatt/year, the data of various risks of death, injury, and diseases are computed in terms of man/day losses by the bureau. They indicate that of the ten forms of power generation, the danger is the least with natural gas, only about a 6 man/day, and nuclear energy is the next least dangerous, about 10 man/day. The danger of using temperature differential of sea water to generate electricity is about 25 man/day, and the most dangerous form of power generation is coal, amounting to three thousand man/day.

    Dr. Agnew notes that the public fails to remember that the electric utilities and equipment manufacturers did not invent nuclear energy; they only choose whether or not to use it to generate power. The effort to regain world leadership in nuclear energy will require recognizing that the rest of the world needs it too. Opposition to the use of nuclear power has been politically effective, in spite of the need to move to a non-petroleum fuel base and without coming up with a viable alternative. The nuclear industry responded to the Three Mile Island accident by taking steps to improve reactor safety, but the industry continues to be threatened because of the suspended reprocessing and breeder programs. The industry must make a compelling case for energy independence to persuade the public that all energy sources, including nuclear, must be developed

    While nuclear energy appears today as a powerful and carbon-free energy, it generates at the same time doubts and apprehension in the general public. Are these fears justified? Is France the most advanced country in the nuclear domain? Should we fear a Chernobyl-like accident in France? Is any irradiation dangerous? What would be the consequences of a terror attack against a reactor? Will nuclear energy be powerful enough to take up the energy reserves challenge? Will the waste management and the nuclear facilities dismantlement be extremely expensive in comparison with the electricity production costs? Do we know how to manage nuclear wastes on the long-term? This book tries to supply some relevant arguments in order to let the reader answering these questions himself and making his own opinion on this topic. (J.S.)

    Since the beginning of the year French media have dealt with a lot of negative information concerning nuclear industry: the dire financial situation of AREVA, the questioning about the state of the pressure vessel of the Flamanville EPR or the EDF and Chinese investments in the british Hinkley point project. All these issues have impacted the opinion of the French people about nuclear energy: more people are against nuclear energy but nuclear accident appears to be only the tenth source of concern after unemployment (first) and terrorism. The debate about the energetic transition that will lead to the decrease of the nuclear share in the production of electricity marks the end of a political consensus in favour of the atom. Solar energy is the favorite energy source, more than 55% of the population wish solar energy to achieve a bigger share in the 15 next years while only 32% wish the same thing for wind energy. For most people nuclear energy appears to be necessary to complement renewable energies for at least the next 15-30 years. (A.C.)

  16. Reconsidering relations between nuclear energy and security concepts

    Relations between nuclear energy and security concepts can be clarified through investigation into the multivocal nature of security concepts. While military uses of nuclear energy significantly influence national security, peaceful uses of nuclear energy contribute energy security, which is an expanded concept of national security. Military and peaceful uses of nuclear energy have reciprocal actions, thus influencing national security and energy security, respectively. Nuclear security, which means security of nuclear systems themselves, recently attracts the attention of the international society. Nuclear security directly influences national security issues. On the other hand, along with nuclear safety, nuclear security becomes a prerequisite for energy security through peaceful uses of nuclear energy. In investigating into relations between nuclear energy and security concepts, the difficulty of translating the English word of 'nuclear security' into Japanese as well as other languages is found.

    2006-07-01

    The Royal Swedish Academy of Sciences (KVA) is an independent non-governmental organization, with expertise in most of the sciences as well as in the economical, social and humanistic fields. The KVA has appointed an Energy Committee that will summarize scientific knowledge on supply and use of energy over the coming fifty years. The Energy Committee has selected a number of subjects to be studied in some depth, one of these being nuclear energy from the fission process. The Energy Committee's key issues concerning nuclear energy: We have identified six key issues which require very careful analysis during the coming years. Safety remains a key issue. It is one of the major activities of OECD's Nuclear Energy Agency. 40 years of multilateral cooperation has led to improvements in the analysis and management of accidents and in the assessment of safety margins in the fuel cycle. In particular, attention is focused on ageing and structural integrity as the lifetime of reactors is extended to up to 60 years. The new Gen III reactors have improved safety features such as double containment, better separation of critical safety systems and improved possibilities to handle steam explosions and core meltdown. The Gen IV reactors will be designed with a goal to further improve safety features. Handling of the nuclear waste: Today, in most light water reactors, the fuel is used once only ('once through') and then sent directly to repositories. After some cooling time, the waste will be buried in underground repositories. Another important aspect is that a final decision for waste disposal is of great importance to the public's acceptance of any new nuclear ventures. The waste handling in future reactors is an important item for research and its solution will also influence how the waste from current reactors is managed. Non-proliferation: With increased use of nuclear energy, more countries may build up facilities for the whole fuel cycle, thus also, at least theoretically

  7. Nuclear energy and independence

    International Nuclear Information System (INIS)

    Rotblat, J.

    1978-01-01

    The pro-nuclear lobby in the United Kingdom won its battle. The Report on the Windscale Inquiry strongly endorsed the application by British Nuclear Fuels (a company owned by the government) to set up a plant to reprocess spent oxide fuels from thermal reactors; a motion in Parliament to postpone a decision was heavily defeated. The Windscale Inquiry was an attempt to settle in a civilized manner what has been tried in other countries by demonstrations and violence. In this exercise, a High Court Judge was given the task of assessing an enormous mass of highly complex technical and medical material, as well as economic, social, and political arguments. The outcome is bitterly disappointing to the objectors, all of whose arguments were rejected. Although the question of whether Britain should embark on a fast breeder reactor program was specifically excluded from the Inquiry, it clearly had a bearing on it. A decision not to proceed with the reprocessing plant would have made a fast breeder program impossible; indeed, the Report argues that such a decision would involve throwing away large indigenous energy resources, a manifest advocacy of the fast breeder. Other arguments for the decision to go ahead with the reprocessing plant included the need to keep the nuclear industry alive, and the profit which Britain will make in processing fuels from other countries, particularly Japan. The author comments further on present UK policy, taking a dissenting view, and then comments on the paper, Nuclear Energy and the Freedom of the West, by A.D. Sakharov

    Fifty million tons of hydrogen are consumed annually in the world in various industrial processes. Among them, the ammonia production, oil refining and the production of methanol. One of the methods to produce it is the electrolysis of water, oxygen and hydrogen. This process needs electricity and steam which a central nuclear It can be your source; Hence the importance of developing the transfer process energy between the two. The objective of the study is to characterize the process of thermal energy transfer from a nuclear power plant to an electrolyzer of intermediate temperature (ITSE) already defined. The study is limited to the intermediate engineering process, from the central to the cell.

  9. Our global energy future and the role of nuclear energy

    International Nuclear Information System (INIS)

    Foster, J.S.

    1991-01-01

    An extension in the use of energy, on even a fairly moderate basis, will, for several decades at least, require the use of all our present energy sources at rates that are a natural extension of historical rates, trending toward maximum practicable exploitation for all but nuclear energy. Regardless of what happens with the fossil hydrocarbons nuclear energy will play a major role in the supply of energy. When the fossil hydrocarbons have run their course nuclear and possibly some solar energy, through the media of electricity, hydrogen and synthetic hydrocarbons, will provide the bulk of the world's controlled energy and in sufficient quantity to provide ample energy for all. The burning question, however, is what will happen in the next few decades. There is a wonderful opportunity for nuclear energy, as the world requirement for energy, and particularly electrical energy, grows

  10. Nuclear energy - some regulatory aspects

    International Nuclear Information System (INIS)

    Jennekens, Jon.

    1980-03-01

    The nuclear industry is often perceived by the public as being uniquely hazardous. As a consequence, the demands placed upon a nuclear regulatory agency invariably include sorting out the valid from the invalid. As the public becomes better informed, more time should become available for regulating the industry. The Canadian nuclear safety philosophy relies upon fundamental principle and basic criteria which licensees must show they are meeting at all stages in the development of a nuclear facility. In reactors, the concept of defence in depth involves the use of well-qualified personnel, compliance with national and international engineering codes and standards, the separation of process and safety systems, frequent testing of safety systems, redundancy in monitoring, control and initiation systems, multiple barriers against fission product release, and strict enforcement of compliance measurements. The Atomic Energy Control Board is writing a set of licensing guides to cover the whole nuclear fuel cycle; however, these will not lead to the impsition of a 'design by regulation' approach in Canada.

    With the rapid growth of human demands for nuclear energy and in response to the challenges of nuclear energy development, the world's major nuclear countries have started research and development work on advanced nuclear energy systems in which new materials and new technologies are considered to play important roles. Nanomaterials and nanotechnologies, which have gained extensive attention in recent years, have shown a wide range of application potentials in future nuclear energy system. In this review, the basic research progress in nanomaterials and nanotechnologies for advanced nuclear fuel fabrication, spent nuclear fuel reprocessing, nuclear waste disposal and nuclear environmental remediation is selectively highlighted, with the emphasis on Chinese research achievements. In addition, the challenges and opportunities of nanomaterials and nanotechnologies in future advanced nuclear energy system are also discussed. (orig.)

  13. Global Energy Challenges of the 21. Century and Nuclear Energy

    International Nuclear Information System (INIS)

    Gagarinskiy, Andrey

    2008-01-01

    The paper considers the world energy demand till the middle of the century, as well as possible forecasting solution for this challenge. On the base of the mathematical model developed in the Kurchatov Institute in 2003- 2006, the vision of the global nuclear energy system and its potential contribution in the energy mix was analyzed. The rate of rapprochement between specific energy consumptions in different countries of the world is a key parameter determining the energy market strain. It was shown that a continuation of the current world trends of this rapprochement would result in an energy resource deficit already in the nearest future. The energy mix picture would contain an 'unsatisfied demand' area of about 10 000 Mtoe of total energy to be consumed by the mid-century Supposing that the mankind has to meet the 'unsatisfied demand' by nuclear energy, the global energy challenges of the 21. century energy do not impose any upper limit on nuclear energy development, the scale of which would be determined by development opportunities. Russia, as one of the pioneers of the First Nuclear Era, possesses great experience of solving the key issues of nuclear energy of the 20. century, and is capable to play an important role in dealing with the challenges faced by nuclear in the 21. century.

  14. Nuclear energy at the turning point

    Energy Technology Data Exchange (ETDEWEB)

    Weinberg, A.M.

    1977-07-01

    In deciding the future course of nuclear energy, it is necessary to re-examine man's long-term energy options, in particular solar energy and the breeder reactor. Both systems pose difficultiies: energy from the sun is likely to be expensive as well as limited, whereas a massive world-wide deployment of nuclear breeders will create problems of safety and of proliferation. Nuclear energy's long-term success depends on resolving both of these problems. Collocation of nuclear facilities with a system of resident inspectors are measures that ought to help increase the proliferation-resistance as well as the safety of a large-scale, long-term nuclear system based on breeders. In such a long-term system a strengthened International Atomic Energy Agency (IAEA) is viewed as playing a central role.

    Connolly, T.J.; Hansen, U.; Jaek, W.; Beckurts, K.H.

    1979-01-01

    In examing the world nuclear energy paths, the following assumptions were adopted: the world economy will grow somewhat more slowly than in the past, leading to reductions in electricity demand growth rates; national and international political impediments to the deployment of nuclear power will gradually disappear over the next few years; further development of nuclear power will proceed steadily, without serious interruption but with realistic lead times for the introduction of advanced technologies. Given these assumptions, this paper attempts a study of possible world nuclear energy developments, disaggregated on a regional and national basis. The scenario technique was used and a few alternative fuel-cycle scenarios were developed. Each is an internally consistent model of technically and economically feasible paths to the further development of nuclear power in an aggregate of individual countries and regions of the world. The main purpose of this modeling exercise was to gain some insight into the probable international locations of reactors and other nuclear facilities, the future requirements for uranium and for fuel-cycle services, and the problems of spent-fuel storage and waste management. The study also presents an assessment of the role that nuclear power might actually play in meeting future world energy demand

    Conventional steelmaking processes involve intensive fossil fuel consumption and CO 2 emission. The system resulting from this study ties a steelmaking plant to a nuclear plant. The latter supplies the former all energy and feedstock with the exception of iron ore. The actual design takes on a multi-disciplinary approach: The nuclear plant employs a proven next-generation technology of fission reactor with 950 °C outlet temperature to produce electricity and heat. The plant construction saving and high efficiency keep the cogeneration cost down. The steelmaking plant employs conventional furnaces but substitutes hydrogen and oxygen for hydrocarbons as reactant and fuel. Water decomposition through an experimentally-demonstrated thermochemical process manufactures the feedstock gases required. Through essential safety features, particular a fully-passive nuclear safety, the design achieves physical proximity and yet operational independence of the two plants to facilitate inter-plant energy transmission. Calculated energy and material balance of the integrated system yields slightly over 1000 t steel per 1 MWt yr nuclear thermal energy. The steel cost is estimated competitive. The CO 2 emission amounts to 1% of conventional processes. The sustainable performance, economical potential, robust safety, and use of verified technological bases attract near-term deployment of this nuclear steelmaking system. -- Highlights: ► A steelmaking concept is proposed based on multi-disciplinary approach. ► It ties advanced nuclear fission reactor and energy conversion to thermochemical manufacture and direct iron making. ► Technological strength of each area is exploited to integrate a final process. ► Heat and material balance of the process is made to predict performance and cost. ► The system rules out fossil fuel use and CO 2 emission, and is near-term deployable.

  18. Nuclear energy: beliefs, values, and acceptability

    Energy Technology Data Exchange (ETDEWEB)

    van der Pligt, J; Eiser, J R

    1985-06-01

    The last decade has seen a dramatic increase in public concern about nuclear energy. As a consequence, it has become recognized that the future of nuclear energy will not only depend on technical and economic factors, but that public acceptability of this technology will play a crucial role in the long-term future of nuclear energy. Research has shown a considerable divergence in public and expert assessment of the risks associated with nuclear energy. Qualitative aspects of risks play a dominant role in the public's perception of risks, and it seems necessary for experts to recognize this in order to improve relations with the general public. It is also clear, however, that differences in the perception of risks do not embrace all the relevant aspects of the public's assessment of nuclear energy. Public reaction is also related to more general beliefs and values, and the issue of nuclear energy is embedded in a much wider moral and political domain. 8 references.

    Miller, J.H. III; Bishop, R.W.

    1992-01-01

    This paper reports that the framework for nuclear regulation in the United States was established by Congress in the Atomic Energy Act of 1954 (AEA). Under the AEA, the nuclear power program in the United States was launched with a technology just being developed and a nuclear power industry in its infancy. The regulations fashioned by the Atomic Energy Commission under the AEA took into account the evolving state of the technology and the emerging industry in those formative years. The process required a utility desiring to build and operate a nuclear power plant to obtain two separate licenses: one authorizing construction and one authorizing operation. At the construction permit stage, generally only preliminary design information was available and a construction permit could be issued with as little as ten to fifteen percent of the facility design completed. Thereafter, design completion, along with research and development required to address open technical issues, progressed in tandem with construction in what is fairly characterized as a design-as-you-go process. Only as plant construction approached completion was the adequacy of the final design evaluated in connection with the operating license review process

    The public opinion in the Netherlands about nuclear energy has been rather stable during recent years. Since the Chernobyl accident roughly 60% of the Dutch population is opposed to extension of the use of nuclear energy. Nuclear experts play an important role in the formation of public opinion about nuclear energy. In this paper the social and cultural background of 87 Dutch nuclear energy experts is analyzed with respect to religious belief, age, life style, membership of a political party, birth order and career pattern. 2 figs., 2 tabs., 16 refs

    2011-03-01

    This report presents facts and figures on new nuclear energy in the Netherlands, in the period after 2020. The information is meant to support a stakeholder discussion process on the role of new nuclear power in the transition to a sustainable energy supply for the Netherlands. The report covers a number of issues relevant to the subject. Facts and figures on the following issues are presented: Nuclear power and the power market (including impact of nuclear power on electricity market prices); Economic aspects (including costs of nuclear power and external costs and benefits, impact on end user electricity prices); The role of nuclear power with respect to security of supply; Sustainability aspects, including environmental aspects; The impact of nuclear power in three nuclear energy scenarios for the Netherlands, within the context of a Northwest European energy market: (1a) No new nuclear power in the Netherlands (Base case), (1b) After closure of the existing Borssele nuclear power plant by the end of 2033, the construction of new nuclear power plant that will operate in 2040. That plant is assumed to be designed not to have a serious core melt down accident (e.g. PBMR) (200 to 500 MWe), (2) New nuclear power shortly after closure the Borssele nuclear power plant in 2033 (1000 to 1600 MWe, Generation 3), and (3) New nuclear power plants shortly after 2020 (2000 to 5000 MWe, Generation 3). Two electricity demand scenario background scenario variants have been constructed based on an average GDP growth of about 2% per year up to 2040. The first variant is based on a steadily growing electricity demand and on currently established Dutch and European Union policies and instruments. It is expected to be largely consistent with a new and forthcoming reference projection 'Energy and Emissions 2010-2020' for the Netherlands (published by ECN and PBL in 2010). A lower demand variant is based on additional energy savings and on higher shares of renewable electricity

    Full text: Radioactive isotopes were introduced to medical treatment in Vietnam very early by M. Curie in 1923. A research reactor has been in operation since 1963 serving up to now an effective base for radioisotope production and nuclear analysis. After reunification of the country, the nuclear technique applications are developing faster and getting widespread. The twenty-year period from 1976 to 1995 was relatively limited by activity of R and D institutions. Nowadays, their interaction with companies demonstrates a dynamic commercialization of nuclear techniques in Vietnam. Investment from government as well as from the private sector has been increased significantly for the last ten years to nuclear medicine and radiotherapy. The radiographic NDT is getting a familiar technique to industry, particularly, in construction of strategy-important industrial and civil projects. NCS are upgraded in different factories, such as mining, ore processing and cement industries. Tracer techniques have shown benefit in oil offshore exploring and in sedimentation management of rivers and harbours. Isotope techniques are playing a competitive role for environmental monitoring and underground water management in the country. Radiation processing is transferred to a commercial scale emphasizing on sterilization of medical products and food preservation. There are still some problems such as public acceptance of radioactive techniques or a lack of both infrastructure and manpower to meet the national demands. However, the government of Vietnam has recently approved the national strategy for peaceful uses of atomic energy, which not only highlights the development of isotope and radiation applications in near future, but also clearly emphasizes the need of nuclear electrical generation by 2017-2020 for the national energy security

    In the next century, the 'fission breeder' concept will not be practical to solve the global energy problems, including environmental and North-South problems. As a new measure, a simple rational Th molten salt breeding fuel cycle system, named 'Thorium Molten-Salt Nuclear Energy Synergetics (THORIMS-NES)', which composed of simple power stations and fissile producers, is proposed. This is effective to establish the essential improvement in issues of resources, safety, power-size flexibility, anti-nuclear proliferation and terrorism, radiowaste, economy, etc. securing the simple operation, maintenance, chemical processing, and rational breeding fuel cycle. As examples, 155 MWe fuel self-sustaining power station 'FUJI-II', 7 MWe pilot-plant 'miniFUJI-II', 1 GeV-300 mA proton Accelerator Molten-Salt Breeder 'AMSB', and their combined fuel cycle system are explained.

    Echavarri, L.

    2002-01-01

    Full text: Nuclear energy is an established component of electricity supply worldwide (16%) and in particular in OECD (nearly a quarter). It is supported by a mature industry benefiting from extensive experience (more than 8 000 reactor years of commercial operation) and dynamic R and D programmes implemented by governments and industries. Existing nuclear power plants are competing successfully in deregulated electricity markets owing to their low marginal production costs, their technical reliability (availability factors exceeding 80% in many countries) and good safety performance. Stringent safety requirements and radiation protection regulations in place in OECD countries allow potential impacts of nuclear energy facilities on human health and the environment to remain extremely low. Furthermore, nuclear energy, a nearly carbon free source, contributes to alleviating the risk of global climate change (worldwide, GHG emissions from the energy sector are already 8% lower than they would be without nuclear energy). Issues related to high-level waste management and disposal are being addressed in comprehensive, step by step approach. Progress towards the implementation of deep geological repositories is being demonstrated (e.g., Yucca Mountain in the US, Olkiluoto in Finland) and research on innovative fuel cycles aiming at partitioning and transmutation of minor actinides is being actively pursued. Up to 2010-2020, nuclear energy will maintain its role mainly through capacity upgrade and lifetime extension of existing plants, in many cases the most cost effective means to increase power capacity and generation. Examples are provided by utility policies and decisions in a number of OECD countries (e.g., Spain, Sweden, Switzerland, UK, US). Although only few new units are being or will be built in the very near term, their construction and operation is bringing additional experience on advanced evolutionary nuclear systems and paving the way for the renaissance of

    The electric utility industry has made a substantial commitment to nuclear power. The industrial capability to produce nuclear plants is large and well established. Nevertheless, nuclear energy in the United States is at the crossroad, and the direction it will take is not at all assured. The postponements, cancellations, and lack of orders for new plants over the past three years raise some serious questions about the future. The present problems of nuclear energy are primarily nontechnical in nature. If the nontechnical issues can be resolved, the future for nuclear looks bright indeed. The LWR and other converters could provide strong competition for coal and other electric power options for a half century or more. If development goals are met, the nuclear breeder offers the prospect of a very large supply of energy at stabilized prices over a time span of centuries

    Recent studies on nuclear energy competitiveness show that considering only the economics this option is the most economic one to generate the base load electricity in most of the countries which do not have plenty of alternative fuels, being this advantage both for the actual prices formation and for their stability on the long term. Should we add the strategic and environmental benefits linked to: Kioto emissions limits, short and long term supply security, national wealth increase due to quality and price of the supply and enhancement of related enterprises, the goodness of nuclear energy to supply a significant share of the electricity demand in most of the countries is evident. For the investors to make decisions for this option, some conditions have to be assured: regulatory stability, favourable national energy policy and expectation for the future, predictable and proven licensing process and expectation for moderate interest rates in the long term.

  8. How competitive is nuclear energy?

    The economic competitiveness of nuclear energy will be crucial for determining its future share in world electricity production. In addition, the widespread liberalization of power markets, in particular in OECD countries, reinforces the role of commercial criteria in technology selection . The recently published IEA/NEA study on Projected Costs of Generating Electricity: 2010 Edition (IEA/NEA, 2010) provides important indications regarding the relative competitiveness of nuclear energy in OECD member countries as well as in four non-OECD countries (Brazil, China, Russia and South Africa). The results highlight the paramount importance of discount rates and, to a lesser extent, carbon and fuel prices when comparing different technologies. Going beyond this general finding, the study also shows that the relative competitiveness of nuclear energy varies widely from one major region to another, and even from country to country. While the study provides a useful snapshot of the costs of generating electricity with different technologies, it does not provide an absolute picture of the competitiveness of nuclear energy. Like any study, Projected Costs of Generating Electricity makes a number of common assumptions about discount rates as well as carbon and fuel prices. In addition, its calculations are based on a methodology that is referred to as the levelised cost of electricity (LCOE), which assumes that all risks are included in the interest or discount rate, which determines the cost of capital. In other words, neither the electricity price risk for nuclear and renewables, nor the carbon and fuel price risk for fossil fuels such as coal and gas, receive specific consideration. The decisions of private investors, however, will depend to a large extent on their individual appreciations of these risks. The competitiveness of nuclear energy thus depends on three different factors which may vary greatly from market to market: interest rates, carbon and fuel prices, and

    At a time when the nuclear question mobilizes attentions and when a new cycle of debates about non-proliferation opens up, the author recalls the constraints and challenges of a nuclear power generation policy. After a brief history of the development of nuclear energy in France and in the rest of the world, the author presents the risks linked with this energy source (TMI and Chernobyl accidents), the particularities of the fuel cycle with its safety and security aspects, and the promises of some past and future reactor technologies (FBR's and fusion reactors). Then, the author stresses on the importance of investments in this domain as illustrated by the launching of new nuclear programs in France, UK, Italy, Finland and in the US, and by the willing of some emerging countries to develop this energy source (China, India, United Arab Emirates, Jordan..). Finally, nuclear energy must not be considered as a privilege of developed countries but should benefit to the rest of the world as well since it promotes economic development thanks to an abundant and cheap energy.

    1984-01-01

    Several heavy-ion accelerators throughout the world are presently able to deliver beams of heavy nuclei with kinetic energies in the range from tens to hundreds of MeV per nucleon, the so-called medium or intermediate energy range. At such energies a large number of final channels are open, each consisting of many nuclear fragments. The disassembly of the collision system is expected to be a very complicated process and a detailed dynamical description is beyond their present capability. However, by virtue of the complexity of the process, statistical considerations may be useful. A statistical description of the disassembly yields the least biased expectations about the outcome of a collision process and provides a meaningful reference against which more specific dynamical models, as well as the data, can be discussed. This lecture presents the essential tools for formulating a statistical model for the nuclear disassembly process. The authors consider the quick disassembly (explosion) of a hot nuclear system, a so-called source, into multifragment final states, which complete according to their statistical weight. First some useful notation is introduced. Then the expressions for exclusive and inclusive distributions are given and the factorization of an exclusive distribution into inclusive ones is carried out. In turn, the grand canonical approximation for one-fragment inclusive distributions is introduced. Finally, it is outlined how to generate a statistical sample of complete final states. On this basis, a model for statistical simulation of complete events in medium-energy nuclear collisions has been developed

    The objective of this document is to present, in a clear and concrete way, the results presented in the book -Nuclear energy an opportunity for Mexico- this book was prepared to evaluate the feasibility of constructing a new nuclear power plant in Mexico considering the evident worldwide rise of the nuclear energy as a way to produce electricity. The worldwide nuclear power renaissance is based on several factors, some of the most important are the uncertainty about the availability and behavior of fossil fuels, the impacts of the green house gases over the environment; improvements in the design and construction process that allow to reduce the construction periods; the competitiveness of nuclear power with other clean technologies and the experience of the nuclear power plant fleet that has shown performance indicators that exceed other technologies. Also, the competitiveness of the nuclear power as base load to satisfy the electricity demand. This book include the actual situation of the nuclear power in the world and the challenges and opportunities to incorporate additional nuclear power plants in Mexico, with the aim of satisfy the future electricity demand, in harmony with the environment and in a secure and safety way. Nonetheless, by itself a nuclear power plant is not the entire or only solution for the environmental and security of supply issues, but nuclear power is a main part of the integral solution where renewable and new clean technologies (e.g. carbon capture and storage and integrated gasification combined cycle) plays an important role. Nowadays, several countries go forward for the use or nuclear power, reinforcing and in some cases restarting their nuclear power programs, Mexico should not be the exception, nuclear power deserves to be included in the portfolio of generation technologies in the future years. The main advantages of nuclear power, as well as the most questionable issues are deeply discussed in the book. (Author)

    China is developing the nuclear data processing code Ruler, which can be used for producing multi-group cross sections and related quantities from evaluated nuclear data in the ENDF format [1]. The Ruler includes modules for reconstructing cross sections in all energy range, generating Doppler-broadened cross sections for given temperature, producing effective self-shielded cross sections in unresolved energy range, calculating scattering cross sections in thermal energy range, generating group cross sections and matrices, preparing WIMS-D format data files for the reactor physics code WIMS-D [2]. Programming language of the Ruler is Fortran-90. The Ruler is tested for 32-bit computers with Windows-XP and Linux operating systems. The verification of Ruler has been performed by comparison with calculation results obtained by the NJOY99 [3] processing code. The validation of Ruler has been performed by using WIMSD5B code.

    The paper provides a historical review of the behaviour of Parliament in the discussion about utilizing nuclear energy. An analysis of the positions taken and reasons advanced so far is necessary, because it is only from its results that promising strategies appropriate to bring about a consensus can be derived. There is no doubt that it is a genuine task of the democratically legitimated bodies to strive for a consensus in energy policy, in particular nuclear energy, in the interest of the whole State, with the legislative, executive and economic bodies combining their efforts. The reservedness of Parliament is regrettable. At the moment, however, there is the positive effect of the discussion being revived. It should be conducted rationally in the joint interest of reaching a political consensus and, on that basis, a broad acceptance of nuclear energy utilization. (orig./HSCH) [de

  2. September 11 and Nuclear Energy

    The terrible September 11 attacks have demonstrated the ability of international terrorists to carry out well-planned and complex operations that can kill thousands of citizens. The potential for biological, chemical and nuclear terrorism has increased and will remain as long as their underlying causes. Nuclear installations could be the targets, or the sources of materials usable for terrorism. Whilst thick containment buildings around nuclear reactors are unlikely to be breached, some installations, such as spent fuel pond are more vulnerable. The safety of nuclear installations must be reconsidered taking into account some new initiating events hitherto considered of very low probability. A resistance against nuclear power plant sabotage by terrorist group penetrating into reactor building, is a controversial topic. Measures against diversion of nuclear materials, which could be used in nuclear terrorism, must be reviewed. The danger of diversion from giant military stocks of highly enriched uranium and plutonium by far exceeds that from peaceful use of nuclear energy. Measures to neutralize these stocks, such as dilution of highly enriched uranium, should be speeded up and have a priority in public concern. As for the nuclear power stations, public should be informed about the recommendations of IAEA for better physical protection of nuclear materials prepared in 1999 (INFCIRC 225/Rev.4) and about Additional protocol to inadequate Convention on Physical Protection of Nuclear Materials from 1980, which is in a process of ratification. For acceptable nuclear future public must be aware that all required measures to eliminate unacceptable risks resulting from terrorist activity against nuclear installations will be undertaken.

    Dr. McKenzie says a national energy policy does exist, being based on synthetic fuels from coal and nuclear energy to meet future demands, and based on a complete lack of attention to conservation. In meeting energy demands for the future, he feels the opportunity still exists to create the scenario that will require meaningful jobs in the process, jobs requiring less capital and less energy. On the risks of nuclear energy, Dr. McKenzie discusses the funding, research, and results of the Atomic Energy Commission's safety program. He airs his views on WASH-1400, the study by Professor Norman Rasmussen, dealing with the possibilities of reactor core meltdowns. He thinks a worse problem resulting from nuclear power plants is that of waste disposal and cites AEC's poor record of managing these wastes in Kansas and elsewhere. In concluding, Dr. McKenzie says: (1) nuclear power may not be the best thing in the world, maybe we should look at other alternatives; (2) conservation is most important, and creates jobs at the same time if handled correctly; (3) AFL-C10 should sponsor a study on energy systems investigating its employment potential, net energy, economic factors, and capital requirements; and (4) construction of nuclear and coal plants will create jobs, but building solar plants will create jobs with fewer restraints on the environment.

    To solicitude of the authorities of the 'Universum' sciences museum of the UNAM, it develops a highly interactive computational system, to provide of information to the population in general about basic principles, uses and benefits of the nuclear energy. The objective is to achieve a better understanding and acceptance of the nuclear technology in our country. The system allows the visualization and simulation of nuclear processes as well as of its applications. The system is divided in three levels: basic, intermediate and simulation. In the basic level multimedia information is included on diverse basic concepts of the nuclear energy. The intermediate level includes the description and operation of some systems of the Laguna Verde nuclear power plant (CNLV). Finally the simulation level contains representative scenarios that the user can control by means of virtual control panels of the main systems of the CNLV. Inside the system a part of interactive games is included with the purpose that the user remembers with more easiness all the concepts and advantages of the nuclear energy mentioned during the previous levels. The system contributes, by means of the development of multimedia computational tools and of simulation, to the popularization of the use and applications of the nuclear energy in Mexico. (Author)

    OAK B202 LARGE-SCALE PRODUCTION OF HYDROGEN BY NUCLEAR ENERGY FOR THE HYDROGEN ECONOMY. The ''Hydrogen Economy'' will reduce petroleum imports and greenhouse gas emissions. However, current commercial hydrogen production processes use fossil fuels and releases carbon dioxide. Hydrogen produced from nuclear energy could avoid these concerns. The authors have recently completed a three-year project for the US Department of Energy whose objective was to ''define an economically feasible concept for production of hydrogen, by nuclear means, using an advanced high-temperature nuclear reactor as the energy source''. Thermochemical water-splitting, a chemical process that accomplishes the decomposition of water into hydrogen and oxygen, met this objective. The goal of the first phase of this study was to evaluate thermochemical processes which offer the potential for efficient, cost-effective, large-scale production of hydrogen and to select one for further detailed consideration. The authors selected the Sulfur-Iodine cycle, In the second phase, they reviewed all the basic reactor types for suitability to provide the high temperature heat needed by the selected thermochemical water splitting cycle and chose the helium gas-cooled reactor. In the third phase they designed the chemical flowsheet for the thermochemical process and estimated the efficiency and cost of the process and the projected cost of producing hydrogen. These results are summarized in this paper

    Rising expectations best characterize the current prospects of nuclear power in a world that is confronted with a burgeoning demand for energy, higher energy prices, energy supply security concerns and growing environmental pressures. It appears that the inherent economic and environmental benefits of the technology and its excellent performance record over the last twenty years are beginning to tilt the balance of political opinion and public acceptance in favour of nuclear power. Nuclear power is a cost-effective supply-side technology for mitigating climate change and can make a substantial contribution to climate protection. This paper reviews the current status of nuclear power and its fuel cycle and provides an outlook on where nuclear power may be headed in the short-to-medium run (20 to 40 years from now). (auth)

    1986-01-01

    A methodology developed to select a preferred nuclear power system for a US Department of Defense (DOD) application has been used to evaluate preferred nuclear power systems for a remote island community in Southeast Asia. The plant would provide ∼10 MW of electric power, possibly low-temperature process heat for the local community, and would supplement existing island diesel electric capacity. The nuclear power system evaluation procedure was evolved from a disciplined methodology for ranking ten nuclear power designs under joint development by the US Department of Energy (DOE) and DOD. These included six designs proposed by industry for the Secure Military Power Plant Program (now termed Multimegawatt Terrestrial Reactor Program), the SP-100 Program, the North Warning System Program, and the Modular Advanced High-Temperature Gas-Cooled Reactor (HTGR) and Liquid-Metal Reactor (LMR) programs. The 15 evaluation criteria established for the civil application were generally similar to those developed and used for the defense energy systems evaluation, except that the weighting factor applied to each individual criterion differed. The criteria and their weighting (importance) functions for the civil application are described

    This study juxtaposes the major facts and arguments about nuclear energy and its potential role in establishing sustainable energy paths. The notion of sustainability has a strong normative character and can be interpreted in a variety of ways. Therefore, also the sustainability of energy supply technologies possesses a normative nature. This paper analyses what the major dimensions are that ought to be addressed when nuclear energy technology is compared, in sustainability terms, with its fossil-fuelled and renewable counterparts. It is assessed to what extent energy supply portfolios including nuclear energy are more, or less, sustainable in comparison to those that exclude this technology. It is indicated what this inventory of collected facts and opinions means for both policy and research regarding nuclear energy in the case of the Netherlands. 32 refs

    In the next years we will face significant switch stands regarding the future energy mix in Europe. In general, European energy policy has to address three energy challenges for a competitive electricity production (1): - Security of supply; - Limitation of greenhouse gas emissions; and - Providing affordable energy to consumers. Regarding climate precaution the goal of a low carbon economy is very ambitious. The NPP in operation already today contribute to all three goals. Nuclear energy generates two thirds of the EU' low carbon electricity, is one of the most economic energy sources and is less vulnerable to fuel price changes, thereby protecting EU economies against the price volatility of raw materials (2). The investment decisions, which have to been taken in the next 5 to 10 years, will determine the electricity production portfolio in the European Union for the next 50 years: 1. Around 800-900 GWe capacity will be required by 2030 to replace the existing capacity and to address increasing demand. 2. More than 50 % of the electricity in 2030 will be generated in plants have not been build today. 3. A total of 57.6 GWe of new nuclear power plants are projected to be commissioned between 2000 and 2030 (3). Only 9.4 GW of these are already certain investments. To ensure sustainable investment decisions, there needs to be reliable and effective framework conditions with the underlying principles: - competition among vendors; - efficient licensing; - solvent capital markets; - political framework; and - public acceptance. With regard to public acceptance, the Commission launched, based on the results of the EU summit in 2007, a platform for a broad stakeholder discussion about risks, challenges and opportunities of nuclear energy, the European Nuclear Energy Forum (ENEF). E.ON is actively involved in both discussion during the annual ENEF-summit and the working group sessions throughout the year. We appreciate these discussion and we face up the pros and

    Clean energies such as nuclear and solar are part of the solution to the energy dependence that we face today and also help us to reduce the greenhouse gas emissions, thus avoiding a global average temperature increase that is irreversible and harmful to all living beings on the planet. Independently the nuclear and solar energies have had a great development in recent years, so in this work we set ourselves the task of creating a synergy between them. First, we conducted a survey of different people involved in the area of energy (energy efficiency, clean energy and renewable sources) in order to know if the area of which they are part influences with respect to the impression that they have of safety in terms of supply, return on investment and safety to the health and environment of another energy source for which we use a correlation analysis. With the results obtained we propose to use photo thermic solar energy as a support to reduce the frequency of accidents by station blackout and we perform the analysis of the combination using the methodology of Probabilistic Analysis of Security with the help of SAPHIRE 7 software to realize the event trees by station blackout of a nuclear power plant and faults for a photo-thermal solar plant. Finally, the decrease in the probability of station blackout from the proposed combination is quantified. The results were favorable to indicate that the probability of station blackout is reduced in half and that is why is suggested to continue studying the combination. (Author)

    Nuclear energy development in Japan has passed about 30 years, and reaches to a step to supply about 35 % of total electric power demand. However, together with globalization of economic and technical development, its future progressing method is required for its new efforts. Among such conditions, when considering a state of future type nuclear energy application, its contribution to further environmental conservation and international cooperation is essential, and it is required for adoption to such requirement how it is made an energy source with excellent economics.The Research Committee on 'Engineering Design on Nuclear Energy Systems' established under recognition in 1998 has been carried out some discussions on present and future status of nuclear energy development. And so forth under participation of outer specialists. Here were summarized on two year's committee actions containing them and viewpoints of nuclear industries, popularization of nuclear system technology, and so forth. (G.K.)

    Today I want to make two key points about the U.S. nuclear energy industry. First, key policy issues are beginning to converge in a way that is very positive for our industry - and for society as a whole. And Second, the industry has worked hard to prepare for the future - and we are ready to make the most of these positive developments. Nuclear energy's prospects are the brightest they have been at any time in history. The plan identifies the building blocks that must be in place before utilities start building the next generation of nuclear plants. One, we wanted to improve the efficiency and reliability of our operating nuclear plants. Two, we wanted to establish a regulatory framework for license renewal. Three, we wanted to develop a more efficient licensing process for new plants. In closing, I am confident that the 21st century will bring a renaissance for nuclear energy-in the United States and around the world. The U.S. nuclear energy industry has a renewed vitality and sense of mission today. We've worked hard preparing for the future- and we will continue to be strong players in worldwide energy policy development in the 21st century. (Cho, G. S.)

    The Department of Energy launched the Nuclear Materials Stewardship Initiative in January 2000 to accelerate the work of achieving integration and cutting long-term costs associated with the management of the Department's nuclear materials, with the principal focus on excess materials. Management of nuclear materials is a fundamental and enduring responsibility that is essential to meeting the Department's national security, nonproliferation, energy, science, and environmental missions into the distant future. The effective management of nuclear materials is important for a set of reasons: (1) some materials are vital to our national defense; (2) the materials pose physical and security risks; (3) managing them is costly; and (4) costs are likely to extend well into the future. The Department currently manages nuclear materials under eight programs, with offices in 36 different locations. Through the Nuclear Materials Stewardship Initiative, progress was during calendar year 20 00 in achieving better coordination and integration of nuclear materials management responsibilities and in evaluating opportunities to further coordinate and integrate cross-program responsibilities for the treatment, storage, and disposition of excess nuclear materials. During CY 2001 the Departmental approach to nuclear materials stewardship changed consistent with the business processes followed by the new administration. This paper reports on the progress of the Nuclear Materials Stewardship Initiative in evaluating and implementing these opportunities, and the remaining challenges in integrating the long-term management of nuclear materials

    Following the industry expansion, the energy consumptions have increased steeply, which have produced the global warming in our lives by carbon production energies. This climate change has provoked significant natural disasters which have damaged to social as well economic matters. Considering the non-carbon production which is the major factor of global warming, nuclear energy is a newly spotlighted source as the green energy source. The climate change factor is affected by the carbon productions made by humans. Then, the nuclear energy increasing rate with the climate change factor affects to the temperature change which is expressed by annual anomaly. Fig. 6 is the protocol for climate change investigation incorporated with the nuclear industry where the climate factor like the temperature is an important index to find out the priority of nuclear energy. The increased environmental pollutions can give the expanding of nuclear energy due to the carbon gas of fossil fuels. This study showed the effectiveness of the nuclear energy by the simulations. The seasonal climate disaster like the very cold winter and very hot summer can increase the necessity of nuclear energy development which could appeal to the general public persons as well as the politicians. So, it is important for the nuclear energy manager to make people understand the importance of the nuclear energy comparing to the oil or coal fuels. The regeneration energy has been considered as the alternative source.

    This article was newly written for useful discussion on energy policy based on the lecture at the Japan Science Council symposium 'How to amend energy policy after the Fukushima nuclear accident' held in July 2012. Basic standpoints of energy policy and positioning of nuclear power according to the 2010 energy basic program were reviewed. Nuclear power capacity was expected to increase from 49.5 GWe in 2007 to 68 GWe in 2030 to assure energy security. The accident forced energy policy to be amended starting with nuclear power zero base. The accident actualized the safety risks of nuclear power utilization, which were discussed from fragilities of three areas: (1) design basis, (2) emergency preparedness/response and (3) regulation system. Concrete measures to reduce risks of nuclear disaster were proposed. Role and responsibility of scientists was commented. Trend of energy policy based on basic philosophy selection for three scenarios in 2030 at the lecture time was confirmed and significance of nuclear power utilization was summarized from many-sided view points.

    The Government's Nuclear Review has given the nuclear industry an opportunity to demonstrate the key role that it can play in developing the UK's energy supply. To fulfil its ultimate potential in both the UK and international markets, nuclear energy must be able to compete in an open market alongside UK fossil fuel based suppliers and with overseas power generators. There are huge potential export opportunities for the nuclear industry, but for the UK to be able to compete in these markets there must be a thriving nuclear sector at home. The Government is now in a position to determine the future development of the nuclear energy industry. A positive commitment to nuclear power will not only be good for the nuclear industry, it will be good for the nation as a whole. (Author)

    In France, 76% of electricity is produced by nuclear power. The industry's pricing levels are among the most competitive in Europe. Thanks to its 58 nuclear reactors France enjoys almost 50% energy autonomy thus ensuring a highly stable supply. Equally, as a non-producer of greenhouse gases, the nuclear sector can rightfully claim to have an environmentally friendly impact. Against a background to increasing global demand with predictions that fossil fuels will run out and global warming a central issue, it is important to use production methods which face up to problems of this nature. There is no question that nuclear energy has a vital role to play alongside other energy sources. (authors)

    The Federal Republic of Germany holds position five on the list of the world's biggest energy consumers. This alone is a fact that puts special emphasis on the public discussion about the peaceful use of nuclear energy, in addition to the current events such as incidents and accidents in nuclear installations. A sober review of the pros and cons of nuclear energy for power generation has to take into account the economic effects and the costs to be borne by the national economy as a result of immediate abandonment of nuclear energy. The article in hand discusses chances, problems, and alternatives to nuclear energy (solar energy and wind power). (orig.) [de

    Human society entered into the society of large energy consumption since the industrial revolution and consumes more than 10 billion tons of oil equivalent energy a year in the world in the present time, in which over 80% is provided by fossil fuels such as coal, oil and natural gas. Total energy consumption is foreseen to increase year by year from now on due to significant economical and population growth in the developing countries such as China and India. However, fossil fuel resources are limited with conventional crude oil estimated to last about 40 years, and it is said that the peak oil production time has come now. On the other hand, global warming due to green house gases (GHG) emissions, especially carbon dioxide, has become a serious issue. Nuclear energy plays an important role as means to resolve energy security and global warming issues. Four hundred twenty-nine nuclear power plants are operating world widely producing 16% of the total electric power with total plant capacity of 386 GWe without emission of CO{sub 2} as of 2006. It is estimated that another 250 GWe nuclear power is needed to keep the same level contribution of electricity generation in 2030. On the other hand, the Japan Atomic Energy Research Institute (JAERI) developed the very high temperature gas-cooled reactor (HTGR) named high temperature gas-cooled engineering test reactor (HTTR) and carbon free hydrogen production process (IS process). Nuclear energy utilization will surely widen in, not only electricity generation, but also various industries such as steel making, chemical industries, together with hydrogen production for transportation by introduction of HTGRs. The details of development of the HTTR and IS process are also described.

    This report is the Proceedings of the Third Specialists` Meeting on High Energy Nuclear Data. The meeting was held on March 30-31, 1998, at the Tokai Research Establishment of Japan Atomic Energy Research Institute with the participation of forty-odd specialists, who were the evaluators, theorists, experimentalists and users of high energy nuclear data including the members of the Japanese Nuclear Data Committee. The need of the high energy nuclear data up to a few Gev has been stressed in the meeting for many applications, such as spallation neutron sources for radioactive waste treatment, accelerator shielding design, medical isotope production, radiation therapy, the effects of space radiation on astronauts and their equipments, and the cosmic history of meteorites and other galactic substances. Since the Second Specialists` Meeting in 1995, such an evaluation activity in Japan has been grown and the results are accumulated. Foreign activities of high energy nuclear data evaluation are also being increased. According to the above situation, with the view point of reviewing and validating an evaluated high energy nuclear data file, project of high energy nuclear data file production, differential and integral experiments, status of evaluation and reviewing methods, processing and transport calculation methods, benchmark tests, international trends, etc. were discussed. The 16 of the presented papers are indexed individually. (J.P.N.)

    Women in Nuclear-Korea (WINK) surveyed the public understanding on various energy resources in early September 2006 to offer the result for establishment of the nuclear communication policy. The reason why this survey includes other energy resources is because the previous works are only limited on nuclear energy, and also aimed to know the public's opinion on the present communication skill of nuclear energy for the public understanding. The present study is purposed of having data how public understands nuclear energy compared to other energies, such as fossil fuels, hydro power, and other sustainable energies. The data obtained from this survey have shown different results according to the responded group; age, gender, residential area, etc. Responded numbers are more than 2,000 of general public and university students. The survey result shows that nuclear understanding is more negative in women than in men, and is more negative in young than older age

    This publication first gives a presentation of a European colloquium on energy strategies between the nuclear risk and the greenhouse effect. Then dealing with the relationship between nuclear energy and nuclear proliferation, a contribution comments the relationship between the civil use of nuclear energy (notably for electricity production) and the use of nuclear materials for nuclear weapons (posture of the five nuclear States, development of the counter-proliferation policy, proliferating countries and actors, evolution of the political context after the fall of the USSR). The next article discusses the rooms to manoeuvre when defining energy strategies, notably with respect to nuclear energy. It also outlines the challenge of energy efficiency improvement in France, particularly for electricity uses, and by limiting the road traffic dramatic increase. A last article is an answer to critics by the author of a book on the greenhouse effect

    1998-11-01

    JENDL High Energy File (JENDL-HE) is being produced by Japanese Nuclear Data Committee (JNDC) to provide common fundamental nuclear data in the intermediate energy region for many applications concerning a basic research, an accelerator-driven nuclear waste transmutation, a fusion material study, and medical applications like the radiation therapy. The first version of JENDL-HE, which contains the evaluated nuclear data up to 50 MeV, is planned to release in 1998. However, a method of integral test with which we can validate the high-energy nuclear data file has not been established. The validation of evaluated nuclear data through the integral tests is necessary to promote utilization of JENDL-HE. JNDC set up a task force in 1997 to discuss the problems concerning the integral tests of JENDL-HE. The task force members have surveyed and studied the current status of the problems for a year to obtain a guideline for development of the high-energy nuclear database. This report summarizes the results of the survey and study done by the task force for JNDC. (author)

    The development of human civilization in general as well as that of every country in particular is in direct relation to the assurance of a cost effective energy balance encompassing all industrial spheres and everyday activities. Unfortunately, the uncontrolled utilization of Earth's energy resources is already causing irreversible damage to various components of the eco-system of the Earth. Nuclear energy used for electricity and hydrogen production has the biggest technological potential for solving of the main energy outstanding issues of the new century: increasing of energy dependence; global warming. Because of good market position the political basis is assured for fast development of new generation nuclear reactors and fuel cycles which can satisfy vigorously increasing needs of affordable and clean energy. Political conditions are created for adequate participation of nuclear energy in the future global energy mix. They must give chance to the nuclear industry to take adequate part in the new energy generation capacity.(author)

  18. India's nuclear energy programme: prospects and challenges

    India has announced ambitious plans to expand its nuclear energy programme nearly 15 fold in the next 20 years, from the current 4,500 MWe to about 62,000 MWe by 2032. By 2020, India's Department of Atomic Energy (DAE) plans to install 20,000 MWe of nuclear power generation capacity (the fifth largest in the world). The department has plans beyond 2030 too. According to these plans India will have the capacity to produce 275 GWe (Giga Watt of electricity) of nuclear power by the year 2052. The DAE's projections are summarised. This is a truly ambitious plan. Without sufficient quantities of energy, India cannot hope to become a global power. Its dream of registering eight to nine per cent economic growth per annum will remain just that, a dream. Even with such ambitious plans on the nuclear energy front, the share of nuclear power in the overall energy mix will remain small. Currently nuclear energy constitutes only about three per cent of the total energy consumed in India. If the current projections are realised, the share of nuclear energy in the total energy output will still be about 20 per cent. India takes pride in its nuclear programme. Over the years, successive governments have fully supported the DAE's plans. This support is likely to continue in the future. In fact, following the Indo-US civil nuclear deal and the Nuclear Suppliers Group (NSG) waiver in 2008, the mood in India has turned upbeat. India is now getting integrated into the global nuclear regime even though it has not signed the Nuclear Non Proliferation Treaty (NNPT). The NSG waiver has, however, allowed India to enter into civil nuclear cooperation with several countries

  19. Hydrogen production as a promising nuclear energy application

    International Nuclear Information System (INIS)

    Vanek, V.

    2003-01-01

    Hydrogen production from nuclear is a field of application which eventually can outweigh power production by nuclear power plants. There are two feasible routes of hydrogen production. The one uses heat to obtain hydrogen from natural gas through steam reforming of methane. This is an highly energy-consuming process requiring temperatures up to 900 deg C and producing carbon dioxide as a by-product. The other method includes direct thermochemical processes to obtain hydrogen, using sulfuric acid for instance. Sulfuric acid is decomposed thermally by the reaction: H 2 SO 4 -> H 2 O = SO 2 + (1/2) O 2 , followed by the processes I 2 + SO 2 + 2H O -> 2HI + H 2 SO 4 and 2HI -> H 2 + I 2 . The use of nuclear for this purpose is currently examined in Japan and in the US. (P.A.)

  20. Nuclear energy and politics in Russian ATWS conditions

    1998-01-01

    Relations between politics and nuclear power in the countries of sustainable development has been many times discussed during the short history of nuclear energy, and regularly arising new events, even very important (in Sweden, USA, etc.), just add to the formed understanding of the problem. Russia for 10 years lives in conditions of a transition period, which seems similar to ATWS-type accidents at nuclear power plants. In these conditions the effect of politics on nuclear power and vice versa are seen very clearly, and, more important, change swiftly, which may present interest for the countries with smoother public processes. The role of political processes in nuclear power is obvious and may be reduced to three main factors: change of political system and transition to market economy have placed nuclear power, though still within state sector, in an absolutely new economic condition, which determine its today's situation as 'Survival'; new possibilities of political influence and opposition to nuclear power (mainly struggle against construction of new nuclear fuel cycle objects) on a levels of authority (local, regional, federal); impact of the USSR collapse on the situation in Russian nuclear power was due sooner to temporary weakening of control and regulatory structures, than to the fact, that some fuel cycle elements have found themselves abroad (the factor of uranium resources' loss is unimportant at present). Nuclear safety was chosen to be the subject of Moscow 1996 Summit, initiated with the purpose of Russia coming closer to G7. The Summit has confirmed the thesis on the possibility of nuclear power o play an important role in the world energy demand in accordance with sustainable development goals. successful activities of Russia-USA Commission for economic and technological cooperation, known as 'Gore-Chernomyrdin' Commission, is to a large extent determined by positive nuclear decisions.

  1. Comparative study of Monte Carlo particle transport code PHITS and nuclear data processing code NJOY for PKA energy spectra and heating number under neutron irradiation

    International Nuclear Information System (INIS)

    Iwamoto, Y.; Ogawa, T.

    2016-01-01

    The modelling of the damage in materials irradiated by neutrons is needed for understanding the mechanism of radiation damage in fission and fusion reactor facilities. The molecular dynamics simulations of damage cascades with full atomic interactions require information about the energy distribution of the Primary Knock on Atoms (PKAs). The most common process to calculate PKA energy spectra under low-energy neutron irradiation is to use the nuclear data processing code NJOY2012. It calculates group-to-group recoil cross section matrices using nuclear data libraries in ENDF data format, which is energy and angular recoil distributions for many reactions. After the NJOY2012 process, SPKA6C is employed to produce PKA energy spectra combining recoil cross section matrices with an incident neutron energy spectrum. However, intercomparison with different processes and nuclear data libraries has not been studied yet. Especially, the higher energy (~5 MeV) of the incident neutrons, compared to fission, leads to many reaction channels, which produces a complex distribution of PKAs in energy and type. Recently, we have developed the event generator mode (EGM) in the Particle and Heavy Ion Transport code System PHITS for neutron incident reactions in the energy region below 20 MeV. The main feature of EGM is to produce PKA with keeping energy and momentum conservation in a reaction. It is used for event-by-event analysis in application fields such as soft error analysis in semiconductors, micro dosimetry in human body, and estimation of Displacement per Atoms (DPA) value in metals and so on. The purpose of this work is to specify differences of PKA spectra and heating number related with kerma between different calculation method using PHITS-EGM and NJOY2012+SPKA6C with different libraries TENDL-2015, ENDF/B-VII.1 and JENDL-4.0 for fusion relevant materials

    2008-01-01

    The energy situation in Europe is mainly characterized by a growth in consumption, together with increasing import dependence in all energy resources. Assuring security of energy supply is a major goal at European Union level, and this can best be achieved by an adequate energy mix, including nuclear energy, producing now 32 % of our electricity. An increase of this proportion would not only improve our independence, but also reduce greenhouse gases emissions in Europe. Another major incentive in favor of nuclear is its competitiveness, as compared to other energy sources, and above all the low dependence of the electricity price on variation of the price of the raw material. The European Commission has launched a series of initiatives aiming at better coordinating energy policies and research. Particular emphasis in future European research will be given on the long-term sustainability of nuclear energy through the development of fast reactors, and to potential industrial heat applications.

    Full text: Application of nuclear energy is actual during last years due to depletion of organic sources of row materials. Therefore, each country develops the programs on peaceful application of nuclear energy and using alternative as well as other energy sources on the basis of the analysis of fuel-energy balance and energy demand state. The Republic of Azerbaijan has huge hydrocarbon resources and alternative energy sources. However, taking into account the fact that hydrocarbon resources can cover increasing energy demand at maximum 50-60 years and renewable energy sources can not meet large energy demand during near future then the discovering of advanced ways on peaceful application of nuclear energy is of great importance. Since the seventies of the twentieth century, wide spectrum of scientific researches on the discovering advanced ways on peaceful application of nuclear energy are carried out in the Republic of Azerbaijan. Among them it is necessary to mark the following directions: radiation modification of the properties of polymers, absorbents, catalysts, metals and alloys, semiconductors, dielectrics, ferroelectrics and various devices; radiation oil-chemistry processes; radiation polymerization; radiation-heterogeneous processes; atomic-hydrogen energy; scientific problems of radiation safety and nuclear security; discovering possibilities for using radiation technologies in the solution of environmental problems; radiation sciences of materials and radiation physics; radiation biology and medicine; application of isotope sources in medicine; application of isotope in oil-gas industry; application of isotope sources in radiography and different fields of technique

  4. Processing and validation of intermediate energy evaluated data files

    International Nuclear Information System (INIS)

    2000-01-01

    Current accelerator-driven and other intermediate energy technologies require accurate nuclear data to model the performance of the target/blanket assembly, neutron production, activation, heating and damage. In a previous WPEC subgroup, SG13 on intermediate energy nuclear data, various aspects of intermediate energy data, such as nuclear data needs, experiments, model calculations and file formatting issues were investigated and categorized to come to a joint evaluation effort. The successor of SG13, SG14 on the processing and validation of intermediate energy evaluated data files, goes one step further. The nuclear data files that have been created with the aforementioned information need to be processed and validated in order to be applicable in realistic intermediate energy simulations. We emphasize that the work of SG14 excludes the 0-20 MeV data part of the neutron evaluations, which is supposed to be covered elsewhere. This final report contains the following sections: section 2: a survey of the data files above 20 MeV that have been considered for validation in SG14; section 3: a summary of the review of the 150 MeV intermediate energy data files for ENDF/B-VI and, more briefly, the other libraries; section 4: validation of the data library against an integral experiment with MCNPX; section 5: conclusions.

    Nuclear partisans and opponents have been fighting for years. On one side, the energy autonomy of France, its electricity exports and the 70000 people employed in the nuclear industry are put forward. On the other side, the accident risk, the cost and dangerousness of waste management are the key words. But, can France, like Germany, really phase out nuclear energy? Is there other solutions? Since the Fukushima accident, what has changed in the pro-nuclear discourse? How strong is the nuclear lobby in France? Can we really have an unbiased debate on this question? The author analyzes the global question of nuclear energy, both in France and abroad, without partiality and political ideology

  6. Nuclear energy in Latin America: needs and possibilities

    Energy Technology Data Exchange (ETDEWEB)

    Crespi, M B.A.

    1979-02-01

    When all forms of primary energy are taken into account, the current energetic situation of Latin America is characterized by a consumption per capita of about 50% of the world average. Assuming that the population will level off at around 1400 million in about a century with a consumption per capita similar to the present one in Western Europe, the total constant asymptotic energy requirement will be 53,000 TWht/year, or about 80% of the current total of the world. This is a conservative assumption, but even so there are only two known sources capable of covering this need, nuclear energy in its advanced forms (fission with breeding and, eventually, fusion) and direct solar energy. The first of these is examined here in that context. Several of the countries of the subcontinent (Argentina, Brazil, Colombia, Chile, Mexico, and Venezuela) have working nuclear centers with at least one small research reactor and Peru has one in installation. Argentina, Brazil, and Mexico have reached the stage in which nuclear power stations are being installed and future ones programmed, and the first of these countries has already one in operation since 1974. Four other countries (Bolivia, Ecuador, Jamaica, and Uruguay) have announced the decision to install integrated nuclear research centers and are at present at different stages of the implementation process. Cuba has a subcritical research facility and has signed an agreement with the USSR to install nuclear stations. In most of the rest, nuclear activities are limited to regular or sporadic utilization of radioisotopes in medical applications, or are non-existent. The three more common commercial power reactor types (PWR, BWR, and CANDU) are represented in the current nuclear programs.

  7. Alternatives to nuclear energy

    International Nuclear Information System (INIS)

    Terrado, E.N.

    1981-01-01

    This article discusses several possibilities as alternatives to nuclear energy and their relevance to the Philippine case. The major present and future fuel alternatives to petroleum and nuclear energy are coal, geothermal heat, solar energy and hydrogen, the first two of which are being used. Different conversion technologies are also discussed for large scale electricity production namely solar thermal electric conversion (STC), photovoltaic electric power system (PEPS) and ocean thermal energy conversion (OTEC). Major environmental considerations affect the choice of energy sources and technologies. We have the problem of long term accumulation of radioactive waste in the case of nuclear energy; in geothermal and fossil-fuels carbon dioxide uranium and accumulation may cause disastrous consequences. With regard to Philippine option, the greatest considerations in selecting alternative energy options would be resources availability - both energy and financial and technology status. For the country's energy plan, coal and geothermal energy are expected to play a significant role. The country's coal resources are 1.4 billion metric tons. For geothermal energy, 25 volcanic centers were identified and has a potential equivalent to 2.5 x 10 6 million barrels of oil. Solar energy if harnessed, being in the sunbelt, averaging some 2000 hours a year could be an energy source. The present dilemma of the policy maker is whether national resources are better spent on large scale urban-based energy projects or whether those should be focused on small scale, rural oriented installations which produced benefits to the more numerous and poorer members of the population.

    A preliminary survey was conducted of the thermonuclear energy release expected during star formation. The destruction of primordial deuterium provides substantial amounts of energy at surprisingly low temperatures, and must be considered in any meaningful treatment of star formation carried to stages in which the internal temperature exceeds a few hundred thousand degrees. Significant energy generation from consumption of initial lithium requires higher temperatures, of the order of a few million degrees. Depletion of primordial beryllium and boron may never provide an important energy source. The approach to equilibrium of the carbon--nitrogen cycle is dominant at temperatures approaching those characteristic of the central regions of main sequence stars. The present calculation should serve as a useful guide in choosing those nuclear processes to be included in a more detailed study. 8 figures, 2 tables

  9. Nuclear power - an inland energy source, in a way. Nuclear electricity generation permits a balanced energy mix

    The primary energy demand of Germany currently is met to more than 50 per cent by imports of crude oil, natural gas and coal, with crude oil imports representing by far the largest quota, due to minor inland resources. Nuclear power is the energy source that reduces the country's dependence on imports, so that, also thanks to the nuclear energy source, oil consumption in Germany could be cut back to half in the years from 1970 until 1995. Although nuclear fuels have to be imported, too, uranium resources are plenty, and fuel supplies in the nuclear fuel cycle are guaranteed, so that this energy source can be considered as a quasi inland energy source.

    For decades the peaceful use of nuclear energy has been regarded as a blessing, the military use, however, as a curse. The scepticism, however, whether this principal difference is justified has increased with the criticism of nuclear energy. Can the one who disposes of nuclear power plants also build nuclear bombs. These questions are posed by Amory Lovins (Soft Energy) and his wife in this work. Against this background the world-wide export of nuclear reactors gains a special explosive effect. The exporters, among them also the Federal Republic of Germany, claim that the military use of the nuclear know-how can be stopped by controls. Reality looks quite different. The authors show that the plutonium being produced in the reactor can be used for military purpose without any big technical efforts and that an effective control of this military use does not exist. On the contrary: nuclear reactors may be the welcome civilian cloak for the production of nuclear bombs. The hard energy-political way which is oriented towards nuclear energy increases the military destruction potential and thus threatens the world peace. To-day, as only one bomb has the total explosive force being used during the Second World War more and more people are of the conviction: we all will explode, the question is only - when.

    Nuclear power has experienced a major boom in the last few years, primarily because it is a non-CO{sub 2} emitting energy source, it can be produced at competitive costs and it can boost a country's security of supply. there are still two issues to be addressed in relation to the currently used technologies: the degree to which the energy content of nuclear fuel is used, and wastes. A solution to both these aspects would ut nuclear power in the category of sustainable energy. The article provides details on current nuclear plans in the wold, the impact of the Fukushima accident on different countries nuclear plans and the European initiatives for sustainable nuclear energy development.

    The French energy policy is supported by a lucid view of the situation of our country and the constraints linked to the international context. This statement implies, the definition of a French policy or energy production essentially based on national resources, uranium, and especially for long term, technical know how which allows using plutonium in breeder reactors. This policy implies an effort in R and D, and industrial development of nuclear field, both in reactor construction and at all levels of fuel cycle. This coherent scientific and financial effort has been pursued since the beginning of years 60, and has placed France among the first nuclear countries in the world. Now this effort enables the mastership of a strong nuclear industry capable to assure the energy future of the country [fr

    Using alternate energy sources abundant in the U.S.A. to help curb foreign oil imports is vitally important from both national security and economic standpoints. Perhaps the most forwardlooking opportunity to realize national energy goals involves the integrated use of two energy sources that have an established technology base in the U.S.A., namely nuclear energy and coal. The coupling of a high-temperature gas-cooled reactor (HTGR) and a chemical process facility has the potential for long-term synthetic fuel production (i.e., oil, gasoline, aviation fuel, hydrogen, etc.) using coal as the carbon source. Studies are in progress to exploit the high-temperature capability of an advanced HTGR variant for nuclear process heat. The process heat plant discussed in this paper has a 1170-MW(t) reactor as the heat source and the concept is based on indirect reforming, i.e., the high-temperature nuclear thermal energy is transported (via an intermediate heat exchanger (IHX)) to the externally located process plant by a secondary helium transport loop. Emphasis is placed on design considerations for the major nuclear heat source (NHS) components, and discussions are presented for the reactor core, prestressed concrete reactor vessel (PCRV), rotating machinery, and heat exchangers

    Nuclear energy may play a significant role in a future sustainable energy mix. The transition from today's nuclear energy system towards a future more sustainable nuclear energy system will be dictated by technology availability, energy market competitiveness and capability to achieve sustainability through the nuclear fuel cycle. Various scenarios have been investigated worldwide each with a diverse set of assumptions on the timing and characteristics of new nuclear energy systems. Scenario-based roadmapping combines the dynamic scenario-analysis of nuclear energy systems' futures with the technology roadmap information published and analysed in various technology assessment reports though integrated within the nuclear technology roadmap Nuclear-Roadmap.net. The advantages of this combination is to allow mutual improvement of scenario analysis and nuclear technology roadmapping providing a higher degree of confidence in the assessment of nuclear energy system futures. This paper provides a description of scenario-based roadmapping based on DANESS and Nuclear-Roadmap.net. (author)

    As nuclear community sometimes feel desperate because the nuclear energy is a very special subject triggering so much controversy among women and young persons especially it has been found that the battle against nuclear energy is just a pretext. Comparing the campaign on a referendum against hydropower - voted in Switzerland in may 1992 it was found astonishingly that exactly the same arguments were applied as during the campaign for the phase out of nuclear energy in 1990. The results were presented at PIME 1991. Voting behaviour for nuclear energy and hydro power are comparable: the gender gap (32% acceptance by men versus 48% by women) found in the 1992 vote about stopping hydropower plants in Switzerland was bigger than the one found in the 1990 vote about nuclear energy. A detailed analysis of these data is presented

    All the countries of the world are promoting the use of atomic energy to provide against high oil prices, climatic changes, and energy security initiative. A domestic and foreign environment for nuclear energy is changing rapidly and 13 leading countries including Korea are trying to develop advanced technologies on Gen IV nuclear energy system through Gen IV International Forum (GIF). To enhance the effectiveness of the future nuclear energy system development plan, a strategic approach is necessary for GIF program and the connection process with the 4th Nuclear Energy Promotion Program and Nuclear Energy R and D Medium and Long Term 5 year Plan for 2012 ∼ 2016 needs to be prepared. This study was to analyze the global nuclear trends of 2012 and the status of GIF program which is international cooperation activities. Also we examined the domestic R and D status of future nuclear energy systems for developing core technology and commercialization of Gen-IV nuclear energy system. A successful performance of this project enables the effective national cooperation with GIF and promotes the public acceptance by suggesting the technical alternatives for the nuclear safety and the spent fuel management.

    The energy supply optimization model MESSAGE-III is improved to evaluate the role of nuclear energy system in Korean long-term energy supply strategy. Emphasis is placed on the potential contribution of nuclear energy in case of environmental constraints and energy resource limitation. The time horizon is 1993-2040. A program to forecast useful energy demand is developed, and optimization is performed from the overall energy system to the nuclear energy system. Reactor and fuel cycle strategy and the expanded utilization options for nuclear energy system are suggested. FBRs, HTGRs and thorium fuel cycle would play key roles in the long run. The most important factors for nuclear energy in Korean energy supply strategy would be the availability of fossil fuels, CO 2 reduction regulation, and the supply capability of nuclear energy.

    Nuclear energy is having a renaissance driven by both old fashioned supply and demand, and environmental concerns. Oil and gas prices have exploded and show no signs of returning to the levels of only a few years ago. Coal is not in short supply, but the pollution it generates has severe economic and health consequences. Concern about greenhouse gases and global warming has caused the environmental movement to begin a reassessment of the role of nuclear in the world's energy portfolio. The full potential of nuclear energy will be achieved only if governments and the public are satisfied that it is safe, that the radioactive waste can be safely disposed of, and that the risk of the proliferation of nuclear weapons is low. The first criterion has been met with designs that are inherently safer than current LWRs, primarily through design simplification, reducing the number of critical components, and advanced control and monitoring technologies. Operating safety has to be assured through good practices and a rigorous, independent inspection process. The second criterion, waste disposal, is a problem where the science and technology (S and T) communities have the primary role in a solution. Many believe that it is solved in principle, but there has as yet been no solution in practice. I will report on where I think we have gotten and what needs to be done. The third criterion, proliferation resistance, is one that the S and T communities cannot solve on their own. The best that S and T can do is to make proliferation difficult, and to make sure that any attempts are discovered early. The rest can be handled only by enforceable international agreements. Safeguards technology needs more attention. (author)

  13. The Security of Energy Supply and the Contribution of Nuclear Energy

    2011-01-01

    What contribution can nuclear energy make to improve the security of energy supply? This study, which examines a selection of OECD member countries, qualitatively and quantitatively validates the often intuitive assumption that, as a largely domestic source of electricity with stable costs and no greenhouse gas emissions during production, nuclear energy can make a positive contribution. Following an analysis of the meaning and context of security of supply, the study uses transparent and policy-relevant indicators to show that, together with improvements in energy efficiency, nuclear energy has indeed contributed significantly to enhanced energy supply security in OECD countries over the past 40 years. Content: Foreword; Executive Summary; 1. The Security of Energy Supply and the Contribution of Nuclear Energy - Concepts and Issues: - Energy supply security: An introduction, - Why security of energy supply remains a policy issue in OECD countries, - The external dimension: import dependence, resource exhaustion and carbon policy, - The internal dimension: economic, financial and technical considerations for energy supply security - Orientations for government policies to enhance the security of energy supply, - Conclusions; 2. Indicators and Models for Measuring Security of Energy Supply Risks: - Introduction, - Different approaches towards designing the Supply/Demand Index, - A detailed review of selected security of supply indicators, - Comprehensive models for assessing the security of energy supply, - The Supply/Demand Index, - Concluding observations; 3.

If new plants are to be built, greater Public acceptance might be realised if they meet the same high level of safety standards throughout the Union. Here the Commission has a very important role to play together with the nuclear regulators and the industry. Greater transparency, better communication and more involvement by the Public in the decision making process - coupled with political will have to address, rather than avoid, the issues - will create the basis for the future of nuclear energy in Europe and elsewhere in the world.

    2002-01-01

    This article is the work of a group of students from the ''Ecole Nationale d'Administration'', they had to study the perspective of nuclear energy in France. Nuclear energy is an important element to assure the stability of the energy supply of the country. Uranium purchases appear to be safe for being diversified and the price of the nuclear fuel contributes to only 20% of the price of the kWh compared to 40% for natural gas. Today the competitiveness of nuclear energy is assured but technological progress concerning gas turbines might challenge it in the years to come. Sustainable development implies not only abundant energy for all but also a preserved environment for the generations to come. The development of nuclear energy is hampered by the lack of satisfactory answers to the problem of fuel back-end cycle and more generally to the issue of radioactive wastes. On the other hand nuclear energy presents serious assets concerning the preservation of environment: nuclear energy as a whole from the uranium ore mining to the production of electricity emits very few atmospheric pollutants and greenhouse effect gases, and requires little room for its installations. The composition of the future energy mix will depend greatly on opinions and assumptions made about the reserves of fossil fuels, technological perspectives and the perception by the public of industrial risks (environmental damage, nuclear accidents...).

  18. The application of contrast explanation to energy policy research: UK nuclear energy policy 2002–2012

    International Nuclear Information System (INIS)

    Heffron, Raphael J.

    2013-01-01

    This paper advances the application of the methodology, contrast explanation, to energy policy research. Research in energy policy is complex and often involves inter-disciplinary work, which traditional economic methodologies fail to capture. Consequently, the more encompassing methodology of contrast explanation is assessed and its use in other social science disciplines explored in brief. It is then applied to an energy policy research topic—in this case, nuclear energy policy research in the UK. Contrast explanation facilitates research into policy and decision-making processes in energy studies and offers an alternative to the traditional economic methods used in energy research. Further, contrast explanation is extended by the addition of contested and uncontested hypotheses analyses. This research focuses on the methods employed to deliver the new nuclear programme of the UK government. In order to achieve a sustainable nuclear energy policy three issues are of major importance: (1) law, policy and development; (2) public administration; and (3) project management. Further, the research identifies that policy in the area remains to be resolved, in particular at an institutional and legal level. However, contrary to the literature, in some areas, the research identifies a change of course as the UK concentrates on delivering a long-term policy for the nuclear energy sector and the overall energy sector. - Highlights: ► Energy policy research is interdisciplinary and needs additional methodological approaches. ► New method of contrast explanation advanced for energy policy research. ► This methodology is based on dialectical learning which examines conflict between sources of data. ► Research example used here is of UK nuclear energy policy. ► Major issues in UK nuclear energy policy are planning law, public administration, and project management

    The third update of the Federal Government's energy programme refers to the subject nuclear energy only with the idea that for energy and industrial political reasons nuclear energy should make a further increasing contribution to power generation in the field of base load. It is true, the annex contains - in form of an abstract - the results of a study of the three energy-economic Institutes which also contain some precise data on the necessary expansion of the Atomic Energy Act. The wording of the update report, however, clearly says that the Federal Government does not adopt the forecastings of the Institutes especially those for the capacity of nuclear power plants considered to be necessary by 1995 (37 000 to 39 500 MW). So, for a number of comprehensible reasons, the Federal Government consciously rejects a nuclear power plant programme such as Government and Parliament have recently decided on in France. Just for this reason, it seems to be reasonable to consider carefully which data and facts have to be taken into account with such a programme and to which results such a - let's say experimental - evaluation could lead. This is the purpose of this contribution. (orig.) [de

    Nuclear energy for electricity generation will extend its market portion in Europe in the coming decades because: 1) its economic and/or environment-relevant advantages compared with the fossil energy sources are so explicit that the latter will no longer be competitive; 2) the improvements of the system engineering, which are presently being implemented and are to be expected in the future, will enhance the safety facilities to the extent that accident risk will cease to be a decisive factor; 3) energy-saving effects or the use of solar energy will not provide an appropriate large scale alternative for coal and/or nuclear energy; 4) the problems of radioactive waste disposal will be definitely solved within the foreseeable future. Considering all the technological systems available the light water reactor will continue to dominate. The change to the breeder reactor is not yet under discussion because of the medium-term guaranteed uranium supply. The use of nuclear technology in the heating market will depend for the moment on the availability and cost of oil and gas development. In principle nuclear energy can play an important role also in this sector

    The United States has embraced nuclear as an important component of its energy future. Triggered by successful passage of the Energy Policy Act in November 2005, four federal initiatives are enjoying some measure of initial success. The first energy authorization act in 13 years, the new legislation contains incentives for up to six new nuclear plants comparable to those for other clean energy sources. Once these incentives were codified, US utilities began to express interest in expanding the nuclear fleet. The Department of Energy's (DOE) push for new nuclear plants, called the 2010 Initiative, has been underway since 2002. Prior to last November, the Nuclear Regulatory Commission (NRC) had no official expressions of interest in building new nuclear plants. Since November, the NRC has been notified of interest in building at least 26 new advanced light water reactors, concentrated at existing nuclear sites in the rapidly growing Southeastern United States. In addition, most of the 103 currently operating plants are expected to obtain 20 year life extensions. Utilities, suppliers and the regulator have been increasing their staffs in anticipation of the new plant orders. Undergraduate nuclear engineering enrollment has surged to its highest level in more than 15 years. The Department of Energy is also moving ahead with its licensing application for a geologic repository at Yucca Mountain. Because exiting legislation limits the amount of spent fuel and nuclear waste that could be stored in the mountain, Congress, DOE and the nuclear industry have become interested in alternative management schemes for the repository. The major DOE initiative is the Global Nuclear Energy Partnership (GNEP), which would close the fuel cycle and introduce advanced fast reactors to manage the long-lived actinides. GNEP also has a major international component, with partnerships to provide reliable fuel supply worldwide to any nation with valid nonproliferation credentials. The United

    Meeting the growing demand for energy, and electricity in particular, while addressing the need to curb greenhouse gas emissions and to ensure security of energy supply, is one of the most difficult challenges facing the world's economies. No single technology can respond to this challenge, and the solution which policy-makers are seeking lies in the diversification of energy sources. Although nuclear energy currently provides over 20% of electricity in the OECD area and does not emit any carbon dioxide during production, it continues to be seen by many as a controversial technology. Public concern remains over its safety and the management of radioactive waste, and financing such a capital-intensive technology is a complex issue. The role that nuclear power will play in the future depends on the answers to these questions, several of which are provided in this up-to-date review of the status of nuclear energy, as well as on the outcome of research and development on the nuclear fuel cycle and reactor technologies

    In 2000 the International Atomic Energy Agency (IAEA) began the International Project on Innovative Nuclear Reactors and Fuel Cycles (INPRO) to help guide nuclear R and D strategies targeted on anticipated mid-century energy system needs. One part of INPRO seeks to develop cost targets for new designs to be competitive in mid-century markets. The starting point was the 40 scenarios of the Special Report on Emissions Scenarios (SRES) of the Intergovernmental Panel on Climate Change. This paper summarizes four of the SRES scenarios, one from each of the four SRES scenario families. It discusses their implications for nuclear energy, including cost targets, and develops for each an 'aggressive nuclear' variant. The aggressive nuclear variants estimate the potential market for nuclear energy if, by improving faster than assumed by the SRES authors, nuclear energy can make inroads into vulnerable market shares projected for its competitors. In addition to projected demands for nuclear generated electricity, hydrogen and heat, the aggressive variants include prospective demand for nuclear desalination and use in upgrading fossil fuels. The paper then presents learning rates and implied cost targets consistent with the aggressive nuclear variants of the SRES scenarios. One provocative initial result is that many of the scenarios with substantial nuclear expansion do not seem to require big reductions in nuclear investment costs. One interpretation discussed at the end of the paper highlights the difference between cost reductions consistent with long-term energy system optimization based on perfect foresight, and cost reductions necessary to attract private investment in today's 'deregulating' and uncertain energy markets.

    The information tells us that since the first chain reaction discovery about 50 years ago up to now, there are more than 400 commercial nuclear power plants connected to electricity supply net works. The electricity supplied by nuclear power plants has exceeded 2000 TWH, which represents almost 17% of the total electricity generated in the world and this proportion is still increasing. The accumulated operating experience of nuclear power plants reach more than 6000 reactor-year. Quite high average life time energy availability factors demonstrate the good reliability of nuclear power plants. The present status of the electricity development in the world shows that nuclear power has become an imperative and exclusively realistic alternative energy source. All of these information demonstrate that nuclear power as a safe, clean and less cost power source has already been widely accepted in the world. In Asia and Pacific region, the fast development of economy provides a vast possibility for the development of nuclear power. In China, shortage of electricity has become the 'bottle neck' which retards the economic development nowadays. China has already drawn up the plan for the development of nuclear power. The information is of great significance to promote the development of nuclear power. It could be said that without information, nuclear power could not be smoothly introduced in any country or region. (J.P.N.)

  8. Nuclear structure in cold rearrangement processes in fission and fusion

    In fission and fusion of heavy nuclei large numbers of nucleons are rearranged at a scale of excitation energy very small compared to the binding energy of the nuclei. The energies involved are less than 40 MeV at nuclear temperatures below 1.5 MeV. The shapes of the configurations in the rearrangement of a binary system into a monosystem in fusion, or vice versa in fission, change their elongations by as much as 8 fm, the radius of the monosystem. The dynamics of the reactions macroscopically described by a potential energy surface, inertia parameters, dissipation, and a collision energy is strongly modified by the nuclear structure of the participating nuclei. Experiments showing nuclear structure effects in fusion and fission of the heaviest nuclei are reviewed. The reaction kinematics and the multitude of isotopes involved are investigated by detector techniques and by recoil spectrometers. The advancement of the latter allows to find very small reaction branches in the range of 10{sup -5} to 10{sup -10}. The experiments reveal nuclear structure effects in all stages of the rearrangement processes. These are discussed pointing to analogies in fusion and fission on the microscopic scale, notwithstanding that both processes macroscopically are irreversible. Heavy clusters, as 132Sn, 208Pb, nuclei with closed shell configurations N=82,126, Z=50,82 survive in large parts of the nuclear rearrangement. They determine the asymmetry in the mass distribution of low energy fission, and they allow to synthesise superheavy elements, until now up to element 112. Experiments on the cold rearrangement in fission and fusion are presented. Here, in the range of excitation energies below 12 MeV the phenomena are observed most convincingly. (orig.)

    The upturn of Korean nuclear power program can be considered to have started in early 70's while future plants for the construction of new nuclear power plants virtually came to a halt in United States. It is projected that power plant systems from combination of nuclear and coal fired types might shift to all coal fired type, considering the current trend of construction on the new plants in the United States. However, with the depletion of natural resources, it is desirable to understand the utilization of two competitive utility technologies in terms of of invested energy. Presented in this paper is a comparison between two systems, nuclear power plant and coal fired steam power plant in terms of energy investment. The method of comparison is Net Energy Analysis (NEA). In doing so, Input-Output Analysis (IOA) among industries and commodities is done. Using these information, net energy ratios are calculated and compared. NEA is conducted for power plants in U.S. because the availability of necessary data are limited in Korea. Although NEA does not offer conclusive solution, this method can work as a screening process in decision making. When considering energy systems, results from such analysis can be used as a general guideline. 2 figs., 12 tabs., 5 refs. (Author)

    Circular economy means no production of waste through re-using and recycling. As other industries, nuclear industry has committed itself to a policy of sustainability and resource preservation. EDF has developed a 5 point strategy: 1) the closure of the fuel cycle through recycling, 2) operating nuclear power plants beyond 40 years, 3) reducing the volume of waste, 4) diminishing the consumption of energy through the implementation of new processes (for instance the enrichment through centrifugation uses 50 times less power than gaseous diffusion enrichment) and 5) making evolve the prevailing doctrine concerning the management of very low level radioactive waste: making possible the re-use of slightly contaminated steel scrap or concrete instead of storing them in dedicated disposal centers.

    Starting from the actual position in the electricity market nuclear energy will grow up to the stabilizing factor in this field. The market penetration of breeding and fusion systems, therefore, will be the next important milestones of nuclear energy development. On the other hand nuclear energy as well as the electric grid itself are good examples for the reconstruction of the non-electric energy market which is dominated by resource and environmental problems. To overcome these problems the installation of a refining step for fossil energy resources and a new transport system besides the electric grid are the next steps toward a crisis-proof energy supply system.

    This paper takes a broad look at the current situation surrounding Japanese nuclear power policy and discusses the necessity of nuclear power from the three angles of the Japanese energy policy: energy security, environmental protection, and economic growth. Moreover, the paper examines a set of issues involved in Japanese nuclear power policy and presents guidelines for the utilization of nuclear energy for peaceful purposes as we head into the 21st century. (1) Energy security: Nuclear power, which is considered a quasi-home-grown energy, is necessary in Japan in order to turn the fragile energy supply structure into a stable one. In this light, the significance of establishing a nuclear fuel cycle and pressing ahead with research and development on fast breeder reactor technology and nuclear fusion is discussed. (2) Environmental protection: Nuclear power does not produce any greenhouse gas in the power generation process. Thus, nuclear power has a central role to play in order for Japan to achieve the greenhouse gas reduction targets agreed upon in the COP3 Kyoto Protocol. Furthermore, the necessity of nuclear power as a means of carrying out measures to arrest global warming not only in the near future but also in the intermediate and distant futures is emphasized. (3) Economic growth: The nuclear power generation system can complete successfully with other power generating technologies in terms of power cost per energy unit. In addition, nuclear power offers many advantages over other forms of energy. For example, the cost of nuclear power is stable because fuel costs account for a smaller percentage of overall costs. Besides these advantages of nuclear power, this paper discusses fast breeder reactors and nuclear fusion as next-generation nuclear energy technologies, both of which are the focus of current research and development efforts. In contrast to the above strengths, the nuclear power industry is confronted by a number of issue that must be solved

  16. CENTRAL NUCLEAR ELECTRIC, A FUTURE OF ROMANIAN ENERGY

    2010-05-01

    Full Text Available Official statistics show the year increasing the share of electricity produced in nuclear power plants. The most developed nuclear energy programs are: the United States, France, Japan, Germany and Canada. Although Romania was among the first countries in Eastern Europe that had a nuclear research program, switching to nuclear power reactors has been extremely difficult and slow. The implications of this decisionmaking process were the first political and then economic. There were a series of oscillations between Wer system offered by the USSR and the CANDU-PHWR supplied by Canada. Considering nuclear reactors Wer insufficiently protected against a nuclear accident, and the total requested by the former Soviet Union on the nuclear fuel cycle, the decision of us have opted for CANDU reactor, fueled with natural uranium, moderated and cooled with heavy water.

    After having recalled the main objectives of the French policy on energy transition (energy efficiency, energy saving, development of renewable energies) and evoked the controversy about the decrease of the nuclear share in the French energy mix, the author recalls the context of development of nuclear energy in France which aimed to ensure an independent electricity supply. Then, the author outlines the benefits of this independence in terms of economy, industrial development and protection of the environment. He discusses the perspectives and challenges of nuclear energy and industry in France with respect to energy transition, to the possibility of life extension for the French nuclear fleet, to the improvement of safety after the complementary safety assessments performed after Fukushima, to the EPR design and to the development of new generations (III and IV) of nuclear reactors, and to new applications of nuclear energy (desalination, transports, district heating). In a last part, the author discusses the perspective of development of nuclear energy in the world

    This report takes stock on the nuclear energy situation in Europe. The European Union with more than 40% of the nuclear power capacity in the world, is already confronted with the nuclear energy place and stakes in the future energy policy. The report si presented in two main parts. The first part, ''the assets and the weaknesses of the nuclear energy'', deals with the economical aspects which historically based the choice of the nuclear energy and the induced impacts on the environment. The competitiveness of the nuclear energy but also the wastes management problem are discussed. The second part, ''the diplomatic and juridical framework of the nuclear energy development'', details and presents the limits of the EURATOM treaty. (A.L.B.)

  19. Low Energy Nuclear Reactions: 2007 Update

    Krivit, Steven B.

    2007-03-01

    This paper presents an overview of low energy nuclear reactions, a subset of the field of condensed matter nuclear science. Condensed matter nuclear science studies nuclear effects in and/or on condensed matter, including low energy nuclear reactions, an entirely new branch of science that gained widespread attention and notoriety beginning in 1989 with the announcement of a previously unrecognized source of energy by Martin Fleischmann and Stanley Pons that came to be known as cold fusion. Two branches of LENR are recognized. The first includes a set of reactions like those observed by Fleischmann and Pons that use palladium and deuterium and yield excess heat and helium-4. Numerous mechanisms have been proposed to explain these reactions, however there is no consensus for, or general acceptance of, any of the theories. The claim of fusion is still considered speculative and, as such, is not an ideal term for this work. The other branch is a wide assortment of nuclear reactions that may occur with either hydrogen or deuterium. Anomalous nuclear transmutations are reported that involve light as well as heavy elements. The significant questions that face this field of research are: 1) Are LENRs a genuine nuclear reaction? 2) If so, is there a release of excess energy? 3) If there is, is the energy release cost-effective?

    Role and potential of nuclear energy system in the energy options is discussed from the viewpoint of sustainable development with protecting from global warming. It is important for mitigation of global warming that the developing countries will use nuclear power effectively. The policy that nuclear power is considered as Clean Development Mechanism would be the good measure for that. (author)
