    The optimum development of regional and local groundwater resources requires a quantitative evaluation of its aquifers and aquicludes, and of the physical and chemical properties relevant to the recharge to and withdrawal of water from them. If an understanding of the groundwater regime is to be obtained, geological observations at outcrop must be augmented by subsurface measurements of the strata and the waters they contain. Measurements of many hydrological and geological parameters can be made in situ by nuclear geophysical well-logging methods. Very simply, well logging consists of lowering a measuring probe into a well and making a continuous record of the variations of a particular parameter with depth. In most circumstances, repetition of the measurements under differing hydrodynamic conditions results in a better definition of the flow regime in the aquifer. Nuclear well-logging techniques have for some years been capable of solving a number of the sub-surface measurement problems faced by hydrogeologists. However, the present usage of these methods varies from country to country and the literature concerning applications is scattered in the professional journals of several disciplines. The objective of this report is to include in a single reference volume descriptions of the physical principles of nuclear logging methods, their applications to hydrogeological problems and their limitations on a level suitable for the practising hydrologists with a limited knowledge of nuclear physics. The Working Group responsible for compiling the report recommended that it should cover a broad spectrum of hydrogeological investigations and problems. For example, it saw no valid reason to distinguish for the purposes of the report between well-logging applications for water-supply purposes and for water-flooding studies in the petroleum industry. Neutron measurements made for soil-moisture determinations in the unsaturated zone have been specifically omitted, however, as

  2. Development of self-learning Monte Carlo technique for more efficient modeling of nuclear logging measurements

    The self-learning Monte Carlo technique has been implemented to the commonly used general purpose neutron transport code MORSE, in order to enhance sampling of the particle histories that contribute to a detector response. The parameters of all the biasing techniques available in MORSE, i.e. of splitting, Russian roulette, source and collision outgoing energy importance sampling, path length transformation and additional biasing of the source angular distribution are optimized. The learning process is iteratively performed after each batch of particles, by retrieving the data concerning the subset of histories that passed the detector region and energy range in the previous batches. This procedure has been tested on two sample problems in nuclear geophysics, where an unoptimized Monte Carlo calculation is particularly inefficient. The results are encouraging, although the presented method does not directly minimize the variance and the convergence of our algorithm is restricted by the statistics of successful histories from previous random walk. Further applications for modeling of the nuclear logging measurements seem to be promising. 11 refs., 2 figs., 3 tabs. (author)

    The history of the nuclear well logging is briefly reviewed. It is discussed that the gamma-ray full-spectrum logging will be the developing trend of the nuclear well logging. Starting from the theory on the gamma-ray and neutron interactions with a geological formation, the discussion is based on the acquisitive capacity of the logging in formations, the ability to solve the problems about the formation evaluation and the geological interpretation in the petroleum prospecting, also the achieved technical level. The current status and the future developments of the γ-spectrum logging are discussed as well

    Spurred by an interest in logging through steel casing γ-ray logging began in the late 1930s followed soon by neutron logging for porosity. These were the first two nuclear well logs. Gamma-gamma density logging was developed during the 1950s. Pulsed neutron lifetime logging appeared in the 1960s; the slim tools came in the early 1970s. Developments since then have included dual detector devices of several types which offered improved measurements or interpretation, γ-ray spectrometry logging (natural and neutron-induced) which identifies certain chemical elements, induced radioactivity logging, and the photoelectric absorption log, which, combined with the density log in a single tool, is known as litho-density logging. A combination of several γ-ray spectrometers in one tool, designed to determine 10 formation elements, was recently introduced, and a new neutron porosity tool measuring epithermal neutron die-away time has been developed. Digital transmission of logging data was a step forward in about 1975. Also, log interpretation techniques have greatly expanded since the advent of digital computers, and the microcomputer has had a distinct impact. It is now practical and economical to do iterative analysis on a suite of logs to obtain an optimum overall interpretation. (author)

    1989-01-01

    Considerations needed in the design and construction of model wells for nuclear log calibration are covered, with special attention to neutron porosity logging and total γ-ray logging. Pulsed neutron decay-time and spectral γ-ray logging are discussed briefly. The American Petroleum Institute calibration facility for nuclear logs is a good starting point for similar or expanded facilities. A few of its shortcomings are mentioned; they are minor. The problem of fluid saturation is emphasized. Attention is given to models made of consolidated rock and those containing unconsolidated material such as Ottawa sand. Needed precautions are listed. A similarity method is presented for estimating the porosity index of formations that are not fully saturated. (author)

    Full Text Available Nuclear logging is one of most important logging services provided by many oil service companies. The main parameters of interest are formation porosity, bulk density, and natural radiation. Other services are also provided from using complex nuclear logging tools, such as formation lithology/mineralogy, etc. Some parameters can be measured by using neutron logging tools and some can only be measured by using a gamma ray tool. To understand the response of nuclear logging tools, the neutron transport/diffusion theory and photon diffusion theory are needed. Unfortunately, for most cases there are no analytical answers if complex tool geometry is involved. For many years, Monte Carlo numerical models have been used by nuclear scientists in the well logging industry to address these challenges. The models have been widely employed in the optimization of nuclear logging tool design, and the development of interpretation methods for nuclear logs. They have also been used to predict the response of nuclear logging systems for forward simulation problems. In this case, the system parameters including geometry, materials and nuclear sources, etc., are pre-defined and the transportation and interactions of nuclear particles (such as neutrons, photons and/or electrons in the regions of interest are simulated according to detailed nuclear physics theory and their nuclear cross-section data (probability of interacting. Then the deposited energies of particles entering the detectors are recorded and tallied and the tool responses to such a scenario are generated. A general-purpose code named Monte Carlo N– Particle (MCNP has been the industry-standard for some time. In this paper, we briefly introduce the fundamental principles of Monte Carlo numerical modeling and review the physics of MCNP. Some of the latest developments of Monte Carlo Models are also reviewed. A variety of examples are presented to illustrate the uses of Monte Carlo numerical models

    1979-01-01

    A nuclear magnetism logging system and method is disclosed in which a surface unit provides power to, control of, and signal reception from a downhole sonde. The surface unit comprises a source of alternating current power and switching circuit means for applying a sequence of alternating current waveforms from the alternating current power source to a surface transformer, each waveform in the sequence starting and stopping with substantially zero amplitude. A rectifier circuit is connected to a polarizing-receiving coil during the polarizing time of the polarizing-receive cycle. A receiving amplifier is connected to the polarizing-receiving coil during the receiving time of the polarizing-receive cycle. Receiver and recording circuits in the surface unit receive and record the downhole signals from the receiving amplifier. Timing circuitry controls a downhole switching circuit means for alternating the connection of the polarizing-receive coil to the rectifier and the receiving amplifier. (Auth.)

    When raw data, e.g. counts or count rates, have been obtained with nuclear logging tools, they have to be processed in order to yield the desired formation properties. Little information is available on this processing. However, it is necessary to understand the processing procedure in order to be able to evaluate its physical correctness, and to understand which corrections are involved. For this reason an analysis has been performed of two sets of field data obtained with neutron porosity and gamma density tools and one data set obtained with a pulsed-neutron capture-gamma tool. Through this analysis it is believed that full insight in the processing of data from the neutron porosity and the gamma density tools has been achieved. The same is not quite the case for the pulsed neutron capture-gamma tool, possibly due to lack of the necessary data. The analysis has also revealed doubt about the physical correctness of some of the features of the processing procedure. (author)

    1982-01-01

    The theory and methodology of the neutron-based technique for the determination of the formation temperature in geothermal fields are discussed. The feasibility of the method was demonstrated before start of the present development phase. The present work is intended to evaluate the response of the temperature probe in a simulated fracture porosity granite matrix at temperatures likely to be encountered in known geothermal reservoirs. An above ground borehole model has been designed and constructed. The effect of high ambient temperatures on the response of the neutron detectors in the probe mockup used in the measurements was investigated and used to correct the detector counts. An improved data analysis method has been developed to account properly for the effects of low porosity and high temperatures. Measurements, using the above ground borehole model, have shown that a linear correlation between the ratio of thermal counts from a Gd-filtered detector to counts from a bare detector and formation temperature is good at temperatures as high as 380/sup 0/F. The present results are consistent with earlier data obtained in high-porosity laboratory models at lower temperatures (T < 167/sup 0/F). Further measurements at high temperature at various porosities and formation neutron absorption cross sections would be necessary for a more extensive comparison.

  12. Nuclear Tools For Oilfield Logging-While-Drilling Applications

    Schlumberger is an international oilfield service company with nearly 80,000 employees of 140 nationalities, operating globally in 80 countries. As a market leader in oilfield services, Schlumberger has developed a suite of technologies to assess the downhole environment, including, among others, electromagnetic, seismic, chemical, and nuclear measurements. In the past 10 years there has been a radical shift in the oilfield service industry from traditional wireline measurements to logging-while-drilling (LWD) analysis. For LWD measurements, the analysis is performed and the instruments are operated while the borehole is being drilled. The high temperature, high shock, and extreme vibration environment of LWD imposes stringent requirements for the devices used in these applications. This has a significant impact on the design of the components and subcomponents of a downhole tool. Another significant change in the past few years for nuclear-based oilwell logging tools is the desire to replace the sealed radioisotope sources with active, electronic ones. These active radiation sources provide great benefits compared to the isotopic sources, ranging from handling and safety to nonproliferation and well contamination issues. The challenge is to develop electronic generators that have a high degree of reliability for the entire lifetime of a downhole tool. LWD tool testing and operations are highlighted with particular emphasis on electronic radiation sources and nuclear detectors for the downhole environment.

    Dowling, D.J.; Arnold, D.M.

    1978-01-01

    A down hole logging tool featuring a neutron generator, an acoustic disturbance generator, and a radiation detection system is described. An array of acoustic magnetostriction transducers is arranged about the target of a neutron accelerator. Two gamma ray sensors are separated from the accelerator target by shielding. According to the method of the invention, the underground fluid at the level of a formation is bombarded by neutrons which react with oxygen in the fluid to produce unstable nitrogen 16 particles according to the reaction 16 O(n,p) 16 N. Acoustic pulses are communicated to the fluid, and are incident on the boundary of the borehole at the formation. The resulting net flow of fluid across the boundary is determined from radiation detection measurements of the decaying 16 N particles in the fluid. A measure of the permeability of the formation is obtained from the determination of net fluid flow across the boundary

  15. Problem of direct task in nuclear magnetism logging

    1986-01-01

    The nuclear magnetism well logging (NML) provides information on the free fluid index (FFI) of a reservoir on the basis of establishing nuclear magnetic polarization in the fluids present in the formation by means of a strong DC magnetic field. In the course of a measurement the value of FFI is estimated from the initial amplitude of the observed proton signal, using an experimentally established relation. The paper deals with the direct task of the NML and presents a theoretical derivation for this empirical function. Only the case of second generation nuclear magnetism logging devices is considered with the assumption that the probe arrangement is centred and the coil in the tool is long enough as compared to its diameter.

  16. Nuclear Well Log Properties of Natural Gas Hydrate Reservoirs

    Science.gov (United States)

    Burchwell, A.; Cook, A.

    2015-12-01

    Characterizing gas hydrate in a reservoir typically involves a full suite of geophysical well logs. The most common method involves using resistivity measurements to quantify the decrease in electrically conductive water when replaced with gas hydrate. Compressional velocity measurements are also used because the gas hydrate significantly strengthens the moduli of the sediment. At many gas hydrate sites, nuclear well logs, which include the photoelectric effect, formation sigma, carbon/oxygen ratio and neutron porosity, are also collected but often not used. In fact, the nuclear response of a gas hydrate reservoir is not known. In this research we will focus on the nuclear log response in gas hydrate reservoirs at the Mallik Field at the Mackenzie Delta, Northwest Territories, Canada, and the Gas Hydrate Joint Industry Project Leg 2 sites in the northern Gulf of Mexico. Nuclear logs may add increased robustness to the investigation into the properties of gas hydrates and some types of logs may offer an opportunity to distinguish between gas hydrate and permafrost. For example, a true formation sigma log measures the thermal neutron capture cross section of a formation and pore constituents; it is especially sensitive to hydrogen and chlorine in the pore space. Chlorine has a high absorption potential, and is used to determine the amount of saline water within pore spaces. Gas hydrate offers a difference in elemental composition compared to water-saturated intervals. Thus, in permafrost areas, the carbon/oxygen ratio may vary between gas hydrate and permafrost, due to the increase of carbon in gas hydrate accumulations. At the Mallik site, we observe a hydrate-bearing sand (1085-1107 m) above a water-bearing sand (1107-1140 m), which was confirmed through core samples and mud gas analysis. We observe a decrease in the photoelectric absorption of ~0.5 barnes/e-, as well as an increase in the formation sigma readings of ~5 capture units in the water-bearing sand as

    In nuclear geophysics, an extension of the nuclear data available for reactor and shielding calculations, is required. In general, the problems and the methods of attack are the same, but in nuclear geophysics the environment is earth materials, with virtually all the natural elements in the Periodic Table involved, although not at the same time. In addition, the geometrical configurations encountered in nuclear geophysics are very different from those associated with reactor and shielding design, and they can impose a different demand on the required accuracy of the nuclear data and on the dependence on the calculational approach. Borehole logging is a very good example, since an experimental investigation aimed at varying only one parameter (e.g. moisture content) whilst keeping all the others constant in a geologically complex system that effectively exhibits 'infinite geometry' for neutrons and γ rays is virtually impossible. An increasingly important are of nuclear geophysics is the on-line analysis of natural materials such as coal (e.g. C, H, O, Al, Si, Ca, Fe, Cl, S, N,) the raw materials of the cement industry (S, Na, K, Al, Si, Ca, Fe, Mn, Ti, P, Mg, F, O), and mined ores of Fe, Al, Mn, Cu, Ni, Ag and Au, amongst others.

    A set of prototype, high temperature logging tools (temperature, pressure and flow) were tested successfully to temperatures up to 275/sup 0/C in a Union geothermal well during November 1978 as part of the Geothermal Logging Instrumentation Development Program. This program is being conducted by Sandia Laboratories for the Department of Energy's Division of Geothermal Energy. The progress and plans of this industry based program to develop and apply the high temperature instrumentation technology needed to make reliable geothermal borehole measurements are described. Specifically, this program is upgrading existing sondes for improved high temperature performance, as well as applying new materials (elastomers, polymers, metals and ceramics) and developing component technology such as high temperature cables, cableheads and electronics to make borehole measurements such as formation temperature, flow rate, high resolution pressure and fracture mapping. In order to satisfy critical existing needs, the near term goal is for operation up to 275/sup 0/C and 7000 psi by the end of FY80. The long term goal is for operation up to 350/sup 0/C and 20,000 psi by the end of FY84.

    1980-11-01

    This report presents the models for interpretation of borehole logs for the PFN (Prompt Fission Neutron) uranium logging system. Two models have been developed, the counts-ratio model and the counts/dieaway model. Both are empirically developed, but can be related to the theoretical bases for PFN analysis. The models try to correct for the effects of external factors (such as probe or formation parameters) in the calculation of uranium grade. The theoretical bases and calculational techniques for estimating uranium concentration from raw PFN data and other parameters are discussed. Examples and discussions of borehole logs are included

  6. Use of critical pathway models and log-normal frequency distributions for siting nuclear facilities

    International Nuclear Information System (INIS)

    Waite, D.A.; Denham, D.H.

    1975-01-01

    The advantages and disadvantages of potential sites for nuclear facilities are evaluated through the use of environmental pathway and log-normal distribution analysis. Environmental considerations of nuclear facility siting are necessarily geared to the identification of media believed to be sifnificant in terms of dose to man or to be potential centres for long-term accumulation of contaminants. To aid in meeting the scope and purpose of this identification, an exposure pathway diagram must be developed. This type of diagram helps to locate pertinent environmental media, points of expected long-term contaminant accumulation, and points of population/contaminant interface for both radioactive and non-radioactive contaminants. Confirmation of facility siting conclusions drawn from pathway considerations must usually be derived from an investigatory environmental surveillance programme. Battelle's experience with environmental surveillance data interpretation using log-normal techniques indicates that this distribution has much to offer in the planning, execution and analysis phases of such a programme. How these basic principles apply to the actual siting of a nuclear facility is demonstrated for a centrifuge-type uranium enrichment facility as an example. A model facility is examined to the extent of available data in terms of potential contaminants and facility general environmental needs. A critical exposure pathway diagram is developed to the point of prescribing the characteristics of an optimum site for such a facility. Possible necessary deviations from climatic constraints are reviewed and reconciled with conclusions drawn from the exposure pathway analysis. Details of log-normal distribution analysis techniques are presented, with examples of environmental surveillance data to illustrate data manipulation techniques and interpretation procedures as they affect the investigatory environmental surveillance programme. Appropriate consideration is given these

    1979-01-01

    This work presents the FLOZ program for nuclear well logging data interpretation. Program has been written in FORTRAN 1900 language for ODRA 1300 computers. The description of the program possibilities and the ways of its application are given. Short presentation of the interpretation method used here and the description of the program work with its complete listing, together with the explanatory commentaries are also presented. The type of interpretation performed by the program depends upon the kind of nuclear logging of interest. For neutron-gamma and gamma-gamma logging the program introduces the corrections for the following disturbing factors: the ratemeter time constant, the logging speed, the apparatus dead time, the gamma-ray background. The gamma-ray logging is corrected for the following disturbing factors: ratemeter time constant, the logging speed, the apparatus dead time of tool, borehole radius, gamma-ray absorbtion in the borehole liquid and the finite thickness of the layers. The calibration constant for gamma-ray probe can be introduced for calculations of radioactivity ore grades. The log deflections being the input data for the FLOZ program, are taken from specially prepared magnetic tape. The results of interpretation are written on magnetic tape, according to the X3GY system for the ODRA 1300 computers. The method of interpretation which is applicated in program FLOZ was elaborated by Prof. J.A. Czubek from Institute of Nuclear Physics in Cracow. (author)

    Fallen logs are the main regeneration sites for Abies sachalinensis (Sachalin fir) in subboreal forests in Japan. We surveyed the spatial genetic structure of different demographic stages in a 4.29-ha natural population of A. sachalinensis. Genetic structure was significant at short distances throughout all stages in this wind-dispersed conifer. To evaluate the effects of fallen-log-dependent recruitment on demography and spatial genetic structure, we conducted parentage analysis of offspring with highly polymorphic nuclear simple sequence repeat and chloroplast simple sequence repeat markers, and developed a new hierarchical Bayesian model to estimate the effects of mother trees and fallen logs on seed dispersal and offspring recruitment. Combined application of nuclear and chloroplast simple sequence repeat markers allowed us to unambiguously identify mother trees of most offspring (> 90%). Female reproductive success was extremely skewed; a few adults produced most of the offspring on fallen logs. Limited distance of effective dispersal and recruitment was seen in the parentage analysis and modelling estimation. These recruitment characters of A. sachalinensis, with a fallen-log-dependent recruitment process, may result in significant genetic structure in early demographic stages.

    In preparation for the upcoming implementation of a thermal oil recovery project, an intensive delineation campaign was recently conducted in a specific area of the Junin block main field of Petrocedeno, operated by Petroleos de Venezuela SA (PDVSA) Petrocedeno joint venture. A complete acquisition program was defined in terms of conventional logging (GR, resistivity, neutron/density, sonic, formation pressure), coring, and unconventional logging with imagery logs and nuclear magnetic resonance (NMR) with the objective of delineating the field. The purpose of this paper was to show the significant added value and step forward the NMR acquisition brought in fluid and reservoir characterization. The paper described the input of standard NMR logging, including fluid characterization; petrophysical support; tool limitation; NMR gamma inversion reprocessing; methodology; and application to EOR project area. Applications for field development were also presented including application for cold and hot production development. It was concluded that the NMR is a suitable tool for fluid characterization and for improving future development of the Petrocedeno extra heavy oil field. It has the capability of identifying fluids that are poorly characterized, or not characterized, by conventional logs. 10 refs., 18 figs.

    Nuclear energy recently celebrated the 50th anniversary of its birthday and after some 30 years of industrial life, it presents impressive achievements in the world and more precisely in Europe. However, nuclear energy seems to be a turning point for its development. In the first period of its development, during the last 50 years, nuclear energy has overcome enormous technical challenges. Nuclear energy is already engaged in develop ping the future nuclear technologies on an international level. What is left to be done is to promote worldwide a safety culture and to enhance and adapt communication efforts

    1979-01-01

    The authors examine the current status of the theoretical development of multisonde neutron logging (MNK) and address the following problems in the area of MNK interpretation: 1) the formation of a multigroup, final-differential set program to calculate direct problems in the empirical curve relationships of MNK; 2) the physical nature of transfer and distribution of neutrons in a well-strata system (utilizing a simplified analytical theory); 3) the selection of the type of thermal and non-thermal neutron particles to be recorded by gamma radiation capture (which is based on a comparative analysis of total and partial error in determining the water content of strata utilizing each of these MNK modifications); 4) developing a system of calculative departure curves for both reinforced and non-reinforced oil and gas wells; 5) the construction of MNK diagrams for final strata thickness; 6) an approximation of analytical-numerical solutions to inverse MNK problems based on an analogaous inverse INNK (impulsed neutron-neutron logging) solutions; 7) an appraisal of the MNK method and associated theories for optimizing instruments and determining the limits to the information provided by this method. The need to continue research in the above areas 1, 4, 6, and 7 is underscored. Such research should be conducted on a three-dimensional rapid-acting calculation algorithm based on physical modeling.

    The objective of this study is to examine factors and prospects for a resumption in growth of nuclear power in the United States over the next decade. The focus of analysis on the likelihood that current efforts in the United States to develop improved and safer nuclear power reactors will provide a sound technical basis for improved acceptance of nuclear power, and contribute to a social/political climate more conducive to a resumption of nuclear power growth. The acceptability of nuclear power and advanced reactors to five social/political sectors in the U.S. is examined. Three sectors highly relevant to the prospects for a restart of nuclear power plant construction are the financial sector involved in financing nuclear power plant construction, the federal nuclear regulatory sector, and the national political sector. For this analysis, the general public are divided into two groups: those who are knowledgeable about and involved in nuclear power issues, the involved public, and the much larger body of the general public that is relatively uninvolved in the controversy over nuclear power

    Nuclear well logging, including natural gamma ray, density, and neutron-porosity techniques are used with electrical well logging of long and short normal techniques to characterize the basaltic areas largely extended in Southern Syria. Statistical analysis approach with the threshold concept has been adapted for such characterization, where four kinds of basalt have been identified: very hard basalt, hard basalt, fractured basalt, and basalt alteration products. The spectrometric gamma technique has also been applied on the retrieved rock samples in order to determine the radioactive content (eU, eTh, and K%) of the basaltic section in the study area. No radioactive anomalies have been detected, the radioactive values are normal and in the expected range.

    The nuclear manpower development project has concentrated on the systemisation and specialization of education and training programs and has actively carried out diverse activities to create new nuclear courses based on the experience of the Nuclear Training and Education Center (NTC) accumulated over the past years. As the demand of education program for training nuclear manpower is increasing due to the remarkable growth of nuclear industry, NTC developed customized education programs making the most use of nuclear experiment equipment and providing practical exercise with research reactor. For improving organizational performance and the development of skilled manpower, KAERI-ACE 2.0 system offered diverse programs addressing the type of occupation and position based on individual competency. Also education on IT was carried out to improve public relations on nuclear and field trips were arranged to encourage local residents' better understanding of the nuclear industry. As a continuous effort, In 2011, NTC specially conducted a survey of employees who are attached to small and medium sized business, and analyzed the present business situations and education requirements for the development of a Pre/under job education program. Prior to this, a briefing session took place for mutual exchange of opinions of industry and academia, based on which a test operation on 'Basic Radiation Education' was carried out. This program has a significance that it was first step toward connection between the nuclear industry and academia as well as an opportunity to educate the employee involved in nuclear engineering field. In 2012, this program is planned to be expanded. With reference to the in-house training, NTC established an 'e-HRD system' providing available resources concerned with education program for cultivating talented personnel. All the education programs are based on individual competency. The e-HRD system will be test operated in 2012 and applied to the

    2010-11-01

    This report presents an initial review of the state-of-the-art nuclear and non-nuclear well logging methods and seeks to understand the technical and economic issues if AmBe, and potentially other isotope sources, are reduced or even eliminated in the oil-field services industry. Prior to considering alternative logging technologies, there is a definite need to open up discussions with industry regarding the feasibility and acceptability of source replacement. Industry views appear to range from those who see AmBe as vital and irreplaceable to those who believe that, with research and investment, it may be possible to transition to electronic neutron sources and employ combinations of non-nuclear technologies to acquire the desired petro-physical parameters. In one sense, the simple answer to the question as to whether petro-physical parameters can be sensed with technologies other than AmBe is probably "Yes". The challenges come when attention turns to record interpretation. The many decades of existing records form a very valuable proprietary resource, and the interpretation of subtle features contained in these records are of significant value to the oil-gas exploration community to correctly characterize a well. The demonstration of equivalence and correspondence/correlation between established and any new sensing modality, and correlations with historic records is critical to ensuring accurate data interpretation. Establishing the technical basis for such a demonstration represents a significant effort.

    The preliminary scope and contents of the IAEA handbook is presented. The work consists of two tasks: one is the book itself containing graphs, tables and the necessary explanatory texts, the second is a computer tape containing nuclear data: cross-sections, spectra of neutron sources, and decay data for a number of selected isotopes. The data will be supplemented by a number of codes to process cross section data. The need of covariance information is discussed and some doubts are raised about the benefits of using this kind of information in treating well logging data

    It is generally believed that noninvasive scanning of hardwood logs such as computer tomography (CT) scanning prior to initial breakdown will greatly improve the processing of logs into lumber. This belief, however, has not translated into rapid development and widespread installation of industrial CT scanners for log processing. The roadblock has been more operational...

    The industry-university-research collaborative education is aiming at developing national nuclear human resources to satisfy with the increasing needs from the industry. For this efforts are being made to develop curricula customized to respective industry needs by improving existing ones. As the demand for training programs for the university students and domestic nuclear personnel was increasing owing to revitalization of nuclear industry, Nuclear Training Center (NTC) improved previous education programs to meet the needs. NTC has operated 2 education programs on research reactor experiments for the university students, and 18 programs on nuclear technology related experiment courses in 2010. Furthermore, the NTC developed new education programs related to 'standardized research reactor system design'. Also the request from universities for internship programs was increased by about three times in 2010 compared to those of the previous year, and this required to develop relevant curricula. In 2005, NTC developed KAERI-ACE, as a unique competency-based staff education system of Korea Atomic Energy Research Institute (KAERI). Based on the system, the NTC has performed 'systematic education'. In 2008, NTC was awarded Best HRD(Human Resource Development) in Public sector for the first time as a government-supported research institute. In 2009, the system was improved to become KAERI-ACE 2.0, based on which, in 2010, NTC improved and diversified education programs including various cyber training programs

    1994-01-01

    The proposed Kachchh Tidal Power Project (KTPP) envisages single-effect single-basin development by constructing a barrier of about 3.25 km length across Hansthal creek. The drilling at Hansthal creek has revealed that bedrock is not encountered even down to a depth of 50 m and subsurface material is mainly marine clay mixed with sand. In order to design foundation on such subsurface materials it was necessary to assess the nature of foundation strata at different depths. Conventional geotechnical investigation and other geophysical methods were not suitable because of limitations of the methods. Nuclear logging being the suitable method was adopted for the first time for offshore investigation at KTPP site to determine subsoil parameters such as bulk density, dry density, bulk moisture, natural moisture content, porosity, void ratio, degree of saturation, etc.. By these studies it was possible to determine variation in the physical characteristics of subsoil and also to evaluate compact and weak zones. The soil properties determined by nuclear logging will be helpful to the design engineers while designing the foundation and adopting remedial measures. (author). 3 refs., 1 tab., 2 figs

    An extensive discussion of problems concerning the development of nuclear power took place at the fifth regular session of the IAEA General Conference in September-October 1961. Not only were there many references in plenary meetings to the nuclear power plans of Member States, but there was also a more specific and detailed debate on the subject, especially on nuclear power costs, in the Program, Technical and Budget Committee of the Conference. The Conference had before it a report from the Board of Governors on the studies made by the Agency on the economics of nuclear power. In addition, it had been presented with two detailed documents, one containing a review of present-day costs of nuclear power and the other containing technical and economic information on several small and medium-sized power reactors in the United States. The Conference was also informed of the report on methods of estimating nuclear power costs, prepared with the assistance of a panel of experts convened by the Agency, which was reviewed in the July 1961 issue of this Bulletin

    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

    2007-01-01

    Building capacity for the safe application of nuclear technologies produces tangible socioeconomic benefits to developing countries. Identifying killer infections such as extrapulmonary tuberculosis and drug resistant strains of HIV/AIDS in sub-Saharan Africa; Monitoring malaria drug resistance in Myanmar; - Teaching Jordanian farmers how to produce viable crops on salty soils; - Investigating water resources deep beneath the Nubian Desert; - Fighting acid rain in Poland; - Creating an energy strategy for Latin America; - Strengthening the security of nuclear sources in Kazakhstan. These are just some of examples of the practical ways in which the International Atomic Energy Agency (IAEA) fulfils its mandate to 'accelerate and enlarge the contribution of atomic energy to peace, health, and prosperity throughout the world'. And some of the reasons the IAEA's long history of global action was recognized through the Nobel Peace Prize in 2005. This list of activities reflects the diverse needs of Member States. It also demonstrates the enormous potential of nuclear technology and the breadth of expertise that lie within three IAEA technical programmes: Nuclear Sciences and Applications, Nuclear Energy, and Nuclear Safety and Security. More importantly, it speaks to the success of a determined effort to facilitate knowledge sharing and technology transfer through a cross-cutting mechanism known as the technical cooperation programme. Each year, the technical cooperation programme disburses approximately US $90 million, all of which is acquired through voluntary contributions from Member States. The programme concentrates on building capacity through training and education, expert advice, and equipment delivery. It is currently active in more than 110 countries across four geographic regions: Africa, Asia and the Pacific, Europe and Latin America

    Groseclose, B. Clark

    1970-01-01

    The nuclear explosive itself is the point about which the Plowshare program revolves. The energy potential of a thermal neutron fissionable material such as Pu 239 or U 235 of ∼17 kt/kg or of Li 6 D of ∼60 kt/kg is indeed impressive. Such large energy densities allow many applications for nuclear explosives that are unthinkable for conventional high explosives. This country has been involved in the design of nuclear explosives for almost thirty years. A question often asked is, 'Why do we still need design effort on nuclear explosives? Hasn't all the possible design work been done?' In a partial reply, let me give an analogy. Why work on nuclear reactors? They were successful even before the first explosive worked. Why should new accelerators be designed? They have worked for many decades. The obvious answer to these questions is that new data, new theories, new insights into the problems and thus new possibilities are found and new requirements are continually being formulated. The development of larger and faster computers has allowed an enormous increase in the design calculations for nuclear explosives. Approximations in the physics involved in the calculations must be made in order to obtain solutions in a finite time, but these approximations can be 'made more accurately as the computing capability increases. Additional calculational capability also allows the designer to examine his design under a variety of possible conditions and configurations. The net effect is a much more sophisticated design. New developments in the area of materials and material, properties open doors that have hitherto been closed. We have seen an increasing emphasis on the interaction of the explosive with its environment. Very specific applications require tailored features such as low fission yield, low fusion yield, low residual radioactivity in particular species, small diameter, low weight, low cost, etc. The Plowshare program in particular imposes stringent requirements on

    The role of nuclear energy has been reevaluated from the point of addressing climate change and energy security concerns, and Nuclear Renaissance has come worldwide. According to the projections of the installed nuclear generating capacity in the world by various specialized agencies, the growth of nuclear capacity of the so-called developed countries (OECD member countries) is slow, that of transition economies (mainly former Soviet Union countries) is moderate, but that of developing countries increases significantly. Nearly two dozens of developing countries plan or consider constructing nuclear power plants. Many Middle Eastern Nations envisage both desalination and electricity generation by nuclear power. Movement of the Nuclear Renaissance is to be realized through international cooperation, based on the '3S' basic principle, i.e. safeguards (nuclear non proliferation), nuclear safety and nuclear security.

  14. Porosity and hydraulic conductivity estimation of the basaltic aquifer in Southern Syria by using nuclear and electrical well logging techniques

    Science.gov (United States)

    Asfahani, Jamal

    2017-08-01

    An alternative approach using nuclear neutron-porosity and electrical resistivity well logging of long (64 inch) and short (16 inch) normal techniques is proposed to estimate the porosity and the hydraulic conductivity ( K) of the basaltic aquifers in Southern Syria. This method is applied on the available logs of Kodana well in Southern Syria. It has been found that the obtained K value by applying this technique seems to be reasonable and comparable with the hydraulic conductivity value of 3.09 m/day obtained by the pumping test carried out at Kodana well. The proposed alternative well logging methodology seems as promising and could be practiced in the basaltic environments for the estimation of hydraulic conductivity parameter. However, more detailed researches are still required to make this proposed technique very performed in basaltic environments.

    2017-12-01

    Over the past six years, we have developed a suite of open-source, low-cost, and lightweight data loggers for scientific research. These loggers employ the popular and easy-to-use Arduino programming environment, but consist of custom hardware optimized for field research. They may be connected to a broad and expanding range of off-the-shelf sensors, with software support built in directly to the "ALog" library. Three main models exist: The ALog (for Autonomous or Arduino Logger) is the extreme low-power model for years-long deployments with only primary AA or D batteries. The ALog shield is a stripped-down ALog that nests with a standard Arduino board for prototyping or education. The TLog (for Telemetering Logger) contains an embedded radio with 500 m range and a GPS for communications and precision timekeeping. This enables meshed networks of loggers that can send their data back to an internet-connected "home base" logger for near-real-time field data retrieval. All boards feature feature a high-precision clock, full size SD card slot for high-volume data storage, large screw terminals to connect sensors, interrupts, SPI and I2C communication capability, and 3.3V/5V power outputs. The ALog and TLog have fourteen 16-bit analog inputs with a precision voltage reference for precise analog measurements. Their components are rated -40 to +85 degrees C, and they have been tested in harsh field conditions. These low-cost and open-source data loggers have enabled our research group to collect field data across North and South America on a limited budget, support student projects, and build toward better future scientific data systems.

    The application of the spectrometric neutron-γ method for coal ash and soil salinity quantitative determinations has been described. The results of field tests for ash-in-coal determinations carried out in dry and water-filled boreholes of eight Australian black coal deposits are discussed. The borehole logging system SIROLOG, now commercially available is described. The latest version of SIROLOG neutron-γ probe achieved values of r.m.s. deviation better than 2% ash in most tests, both in water-filled and dry boreholes and for coals of ash content in the range 3-50%. The laboratory measurements and the preliminary field tests for quantitative logging of salinity in soils are described. A spectrometric neutron-γ method using a 252 Cf source and a BGO detector was applied. Major constraints affecting salinity logging were identified. The most important of these were simulated in laboratory tests and evaluated. (author)

    Well logging data processing is one of the main sources of information in the oil-gas field analysis and is of great importance in the process of its development and operation. Therefore, it is important to have the software which would accurately and clearly provide the user with processed data in the form of well logs. In this work, there have been developed a software product which not only has the basic functionality for this task (loading data from .las files, well log curves display, etc.), but can be run in different operating systems and on different devices. In the article a subject field analysis and task formulation have been performed, and the software design stage has been considered. At the end of the work the resulting software product interface has been described.

    The energy situation in Japan is briefly outlined. Vulnerability in energy structure of the country is shown by a comparison of primary energy supply patterns of Japan and Western countries. Japan's energy policy consists in reducing dependence on oil, promoting efficient use of energy and increasing use of non-fossil fuels. Nuclear power is a core of alternative energy for petroleum because of stable supply of nuclear fuel, low detrimental emissions and less dependence on the fuel. A short historical review of nuclear power development in Japan is presented. Some future issues as development of entire nuclear fuel cycle, social acceptance, reactor safety and nuclear power economics are also discussed. 6 figs. (R.T.)

    Compared with the nuclear fission research which followed that in advanced countries, Japan has treaded on its own track in nuclear fusion development; in the former, she had been far behind other leading countries. Characteristic of the efforts in Japan is the collaboration with educational institutions. Works are now carried out mainly in Tokamak plasma confinement, though other means being studied simultaneously. The nation's fusion research program is the realization of a fusion reactor at the turn of the present century, based on the world-level results attained with Tokamak. Past developments in the nuclear fusion research, the current status, and aspects for the future are discribed. (Mori, K.)

    A storage-type density meter for oil logging has been developed. It constitutes of a 137 Cs source, a NaI scintillation detector, a pulse amplifier, a date storage circuit, a high voltage power supply and a Li ion battery, being integrated into a stainless steel container of Φ60 mm x 1300 mm. Unlike density meters in current uses, this type of density meter goes into an oil well without an armored cable. Density data acquired in the well are stored for data analysis with a PC in laboratory. The density distribution derived from oil well can be a guide for oil exploration. Logging of the density meter can be done with only one crane, for a continuous logging of up to 15 days. (authors)

    Nuclear Power is a new, innovative technology for energy production, seen in the longer historic perspective. Nuclear technology has a large potential for further development and use in new applications. To achieve this potential the industry needs to develop the arguments to convince policy makers and the general public that nuclear power is a real alternative as part of a sustainable energy system. This paper examines the basic concept of sustainable development and gives a quality review of the most important factors and requirements, which have to be met to quality nuclear power as sustainable. This paper intends to demonstrate that it is not only in minimising greenhouse gas emissions that nuclear power is a sustainable technology, also with respect to land use, fuel availability waste disposal, recycling and use of limited economic resources arguments can be developed in favour of nuclear power as a long term sustainable technology. It is demonstrated that nuclear power is in all aspects a sustainable technology, which could serve in the long term with minimal environmental effects and at minimum costs to the society. And the challenge can be met. But to achieve need political leadership is needed, to support and develop the institutional and legal framework that is the basis for a stable and long-term energy policy. Industry leaders are needed as well to stand up for nuclear power, to create a new industry culture of openness and communication with the public that is necessary to get the public acceptance that we have failed to do so far. The basic facts are all in favour of nuclear power and they should be used

    Experience clearly indicates that most developing countries actively planning and implementing nuclear power require broad-scope assistance if their use of nuclear technology is to be safe, economic, and reliable. The IAEA's assistance is directed both to general planning, and to the development of supporting structures and is based on an assessment of needs which cannot be satisfied by other means. The Agency's Division of Nuclear Power has the technical background and tools to support a comprehensive programme of assistance in nuclear power assessment, planning, and implementation. The overall objective of such a programme is to help strengthen national capabilities of executing the following tasks: Analysis of overall energy and electricity demand and supply projections; planning the possible role of nuclear power in electricity supply, through determining the economically optimal extent and schedule for the introduction of nuclear power plants; assessing the available infrastructures and the need, constraints, and possibilities for their development; and developing master schedules, programmes, and recommendations for action. Proposed programmes must be reviewed periodically, and one of the Agency's aims is to ensure that national competence to carry out such reviews exists or can be developed. Training of local staff is therefore one of the most important objectives

    While this article centers on discussing the world need for energy, reviewing some of the problems that are being encountered in meeting that demand, and making some recommendations, the overriding point is that much depends upon America's own internal policies. Most of the nuclear technology-recipient nations are the less-developed countries, and just meeting present needs is forcing them to financial limits in terms of attracting external financing. Meanwhile, the dollar dimensions of ''going nuclear'' are increasing and the fact that it can take eight to ten years before a nuclear plant begins paying out threatens to take proposals for external financing ''off the market.'' There must be direct government support of nuclear plant proposals in recipient nations. There is a parallel need for institutions--such as the United States' own Export-Import Bank--to come up with policies specifically geared to nuclear needs. Both actions should receive support because building those plants is of national importance, both to the exporter and the recipient. In the view of those involved in such financing, there is no doubt the global money markets can meet the demand, but the allocation process needs tailoring to the specific nuclear situation. The export of nuclear power, in a properly competitive atmosphere that does not encourage reduction of protective features and that effectively controls the risks of nuclear power, is one of the most feasible means by which the U.S. can help mankind toward an improved world society

    The aim of this project is to increase the productivity of a large drum chipper by developing a feeder device to be used especially when chipping logging residue. Logging residue from regeneration areas is the most important reserve of forest biomass for the production of renewable energy in Finland. It is possible ecologically and economically to use about 5 million m{sup 3} of logging residue yearly for energy purposes. Currently both large lorry based chippers and smaller forwarder based chippers are used for chipping logging residue. However even the latest versions of these chippers are not well equipped for chipping logging residue. The ball like shape of residue piles causes blockades, if too large amounts of residue are fed into the chipper. Keeping the material flow even is difficult. In this project a prototype of a feeder device will be designed and manufactured to exactly find out the problems, that occur when feeding logging residue to a chipper. The designed prototype is based on a tubular chassis, which supports a conveyor made of steel plates. Prototype also has a 2,5 m wide feeding table and a feeder roll, which is located above the conveyor just before the chipper opening. Both the conveyor and the feeder roll are powered by hydraulic motors. The maximum feeding force is 20 kN. For research purposes both hydraulic pressure and flow can be adjusted individually for both motors. During 1996 activities included designing and building the prototype feeder device. In 1997 the prototype will be tested to find out possible problems, which need to be cured. After problems are solved and other improvements are made, the feeder device will be installed to an existing chipper and then tested again to determine the productivity of the new feeder device compared to the old unit.

    2009-09-01

    Full Text Available The etudy made a description and use of a methodology for evaluating quality cost in a semimechanized    logging   operation   was   developed. For  description  this  goal the logging sub-operations were detailed. The effects of the non conformity of one sub-operation on the succeeding ones were listed and analysed. Those consequences on which a money value could be atributed were specified. The methodology was applied to a case study. Quality cost were divided in three categories: evaluation cost, prevention cost, and faillure cost. It was concluded that the firm is not investing enough in evaluation and prevention causing a faillure cost of R$1.541,11/ha, which is considered too high. The percent composition of this cost was: log spliting 40,96%; error in wood volume determination in the stocking yeard 37,12%; wood waste in the stand 9,52%; non separation of thin logs 8,46%; logs left in the fire control line 1,49%; miscalculation of splited wood volume 1,53%; wood volume remaining in the coppices 0,51%; presence of branches in the fire control line 0,41%. The logs spliting operation must be worked out in order to diminish its cost. Firm profit may be increased throught investiment and research in reducing evaluation and prevention costs. Every waste cost must be avoided because is not only the firm itself, but the whole society who ends up paying the bill.

    The paper discusses the following aspects on the nuclear knowledge management: assimilation of knowledge management, recognition of the nuclear specificity, attracting young talents. Another feature which, possibly, differentiates nuclear from other high-tech industries is that time constraints in some nuclear development may very well exceed the duration of a generation of professionals. That means, not only maintaining scientific and technical knowledge, which, as a minimum, leads to maintain: a rigorous supervision of human resources in quality and quantity; anticipatory planning of human resources, with a special focus on succession planning concerning expertise positions; a steady and continuous effort in training and retraining programs. Maintaining the safety culture is also one of the major managerial duties. Taking full account of the nuclear specificity in knowledge maintenance and development in the AREVA group, requests a multifunctional approach, which combines efforts of Research and Innovation, and Human Resources departments, plus the group Nuclear inspectorate. It is acknowledged that the industry, basically, would readily rely on the capabilities of the academic world and research centers in ensuring that training and education in nuclear science and technologies are attuned to the evolving needs of the industry, in maintaining the proper educational programs and in fostering fruitful cooperations between them

    Engineering problems encountered in the development of nuclear borehole logging techniques are discussed. Spectrometric techniques require electronic stability of the equipment. In addition the electronics must be capable of handling high count rates of randomly distributed pulses of fast rise time from the detector and the systems must be designed so that precise calibration is possible under field operating conditions. Components of a logging system are discussed in detail. They include the logging probe (electronics, detector, high voltage supply, preamplifier), electronic instrumentation for data collection and processing and auxiliary equipment

    To date, the peaceful application of nuclear energy has been largely restricted to the generation of electricity. Even with such an application there is potential for wider use of the nuclear energy generated in providing heat for dwellings, control of climate for the production of vegetables and providing warm water for fish and lobster farming. It is possible to envisage specific applications of nuclear power reactors to process industries requiring large blocks of energy. These and other future developments are reviewed in this report.

    This paper is intended to be a companion to similar papers by OECD/NEA and CMEA and will summarize the nuclear power system plans of developing Member States most likely to have nuclear programmes before the year 2000. The information that is presented is derived from various sources such as the Agency 1974 study of the market for nuclear power in developing countries, the annual publication, ''Power Reactors in Member States - 1976 Edition'', various nuclear power planning studies carried out by the Agency during the period 1975 and 1976, direct correspondence with selected Member States and published information in the open literature. A preliminary survey of the prospects for nuclear power in Member States not belonging to the OECD or having centrally planned economies indicates that about 27 of these countries may have operating nuclear power plants by the end of the century. In the 1974 Edition of the ''Market Survey'' it was estimated that the installed nuclear capacity in these countries might reach 24 GW by 1980, 157 GW by 1190 and 490 GW by the year 2000. It now appears that these figures are too high for a number of reasons. These include 1) the diminished growth in electrical demand which has occurred in many Member States during the last several years, 2) the extremely high cost of nuclear plant construction which has placed financial burdens on countries with existing nuclear programmes, 3) the present lack of commercially available small and medium power reactors which many of the smaller Member States would need in order to expand their electric power systems and 4) the growing awareness of Member States that more attention should be paid to exploitation of indigenous energy sources such as hydroelectric power, coal and lignite

    Radiating formations with isotopes neutron source (Am-Be), and using chlorine element contained in the formation water as a tracer indicator, the chlorine spectrum well logging tool has been regarded as the important and useful tool in the determination of water flooding intensity of formation intervals, especially in the oilfield development stages with high salinity formation water. However, the accuracy of determination of the oil/water-bearings needs to be improved. A new chlorine spectrum logging tool with two detectors has been developed. The short (near) detector uses a He-3 counter tube to measure formation epithermal neutron intensity, the long (far) detector uses a BGO crystal detector to replace traditional Nal detector for measuring the captured X gamma ray spectrum produced by the thermal neutron capture process in the formation. Although the energy resolution of BGO detector to gamma rays is less effective than that of Nal detector, the efficiency of BGO detector to high energy gamma rays is much better. This advantage helps to detect captured chlorine gamma rays, which increases the ability of chlorine element detection. The effect of statistical errors is also reduced. The spectrum autostabilization function in the downhole tool improves the reliability of the whole system. The new chlorine spectrum logging tool can give three log curves simultaneously, these curves are formation porosity, chlorine content, and the ratio of chlorine content and thermal neutron intensity. When formation porosity is larger than 10 p.u, formation water salinity is greater than 40,000 ppm, the resolution to the oil/water-bearings is increased to about 10% compared with the old version tool. Field tests show that the accuracy of water flooding intensity evaluation has been upgraded considerably with the use of new chlorine spectrum logging tool, which contributes greatly to the oilfield development with high salinity formation water 4 refs., 2 tabs., 7 figs.

    Nuclear power is a proven technology which currently makes a large contribution to the electricity supply in a number of countries and, to a much less extent, to heat supply in some countries. Nuclear power is economically competitive with fossil fuels for base load electricity generation in many countries, and is one of the commercially proven energy supply options that could be expanded in the future to reduce environmental burdens, especially greenhouse gas emissions, from the electricity sector. Over the past five decades, nearly ten thousand reactor-years of operating experience have been accumulated with current nuclear power plants. Building upon this background of success and applying lessons learned from the experience of operating plants, new generations of nuclear power plants have been, or are being developed. Improvements incorporated into these advance designs include features that will allow operators more time to perform equipment protection and safety actions in response to equipment failures and other off normal operating conditions, and that will reduce and simplify the actions required. Great attention is also paid to making new plants simpler to operate, inspect, maintain and repair, thus increasing their overall cost efficiency and their compatibility with the infrastructure of developing countries. The paper provides a discussion of future world energy supply and demand projections, current status and prospects for nuclear power, a short summary of advanced reactor concepts and non-electrical applications of nuclear energy for developing countries, and a review of the role of the IAEA.

    Kim, Tony

    2015-01-01

    There are clear advantages of development of a Nuclear Thermal Propulsion (NTP) for a crewed mission to Mars. NTP for in-space propulsion enables more ambitious space missions by providing high thrust at high specific impulse ((is) approximately 900 sec) that is 2 times the best theoretical performance possible for chemical rockets. Missions can be optimized for maximum payload capability to take more payload with reduced total mass to orbit; saving cost on reduction of the number of launch vehicles needed. Or missions can be optimized to minimize trip time significantly to reduce the deep space radiation exposure to the crew. NTR propulsion technology is a game changer for space exploration to Mars and beyond. However, 'NUCLEAR' is a word that is feared and vilified by some groups and the hostility towards development of any nuclear systems can meet great opposition by the public as well as from national leaders and people in authority. The public often associates the 'nuclear' word with weapons of mass destruction. The development NTP is at risk due to unwarranted public fears and clear honest communication of nuclear safety will be critical to the success of the development of the NTP technology. Reducing cost to NTP development is critical to its acceptance and funding. In the past, highly inflated cost estimates of a full-scale development nuclear engine due to Category I nuclear security requirements and costly regulatory requirements have put the NTP technology as a low priority. Innovative approaches utilizing low enriched uranium (LEU). Even though NTP can be a small source of radiation to the crew, NTP can facilitate significant reduction of crew exposure to solar and cosmic radiation by reducing trip times by 3-4 months. Current Human Mars Mission (HMM) trajectories with conventional propulsion systems and fuel-efficient transfer orbits exceed astronaut radiation exposure limits.

    Smith, G.W.

    1977-05-01

    The prompt fission neutron (PFN) method of direct uranium measurement was studied. The PFN uranium logging technique measures the enhanced epithermal neutron population created by the prompt thermal fission of 235 U to assay uranium mineralization around a borehole. This neutron population exists for several hundred microseconds after a pulsed neutron source produces a burst of high energy (14 MeV) neutrons. A feasibility study established the basic relationship between the uranium concentration and the enhanced epithermal neutron count, and defined the major measurement perturbing factors. Following the feasibility study, development of a PFN prototype field probe was undertaken. A laboratory type neutron generator, the Controlatron, was modified for use in the probe. Field evaluation of the prototype system began in January 1976. Comparisons of neutron logs and natural gamma logs taken during this evaluation period clearly define many disequilibrium conditions as verified by ore grade estimates from core samples. The feasibility of the PFN logging technique to detect uranium in-situ has now been demonstrated

  7. Nuclear Power and Sustainable Development

    International Nuclear Information System (INIS)

    2006-04-01

    Any discussion of 21st century energy trends must take into account the global energy imbalance. Roughly 1.6 billion people still lack access to modern energy services, and few aspects of development - whether related to living standards, health care or industrial productivity - can take place without the requisite supply of energy. As we look to the century before us, the growth in energy demand will be substantial, and 'connecting the unconnected' will be a key to progress. Another challenge will be sustainability. How can we meet these growing energy needs without creating negative side effects that could compromise the living environment of future generations? Nuclear power is not a 'fix-all' option. It is a choice that has a place among the mix of solutions, and expectations for the expanding use of nuclear power are rising. In addition to the growth in demand, these expectations are driven by energy security concerns, nuclear power's low greenhouse gas emissions, and the sustained strong performance of nuclear plants. Each country must make its own energy choices; one size does not fit all. But for those countries interested in making nuclear power part of their sustainable development strategies, it is important that the nuclear power option be kept open and accessible

    In the eighties it was not common for girls to study engineering. But a few young girls have always been fascinated by science and technical applications and dared to go for a gender untypical education. What are these female engineers doing today? This paper describes the career development of a woman, who completed her Master of Science in Nuclear Engineering, found first a job in an international company as cooperator in the research group of radiation physics and later as head of technical support and quality assurance of medical systems and then succeeded in a competition to be recruited at the European Commission (EC). There she started as an assistant for the primary standardisation of radionuclides and high-resolution alpha-particle spectrometry including the preparation of radioactive sources in the radionuclide metrology sector at the Institute for Reference Materials and Measurements of the European Commission’s Joint Research Centre and consequently published her work in scientific journals. Today, 29 years later, I am the laboratory responsible for the preparation and characterisation of nuclear targets at EC-JRC-IRMM, leading a team that has unique know-how in the preparation of thin film deposits (called targets) tailor-made for nuclear physics measurements at the EC–JRC–IRMM and international accelerator sites. High quality measurements of nuclear data and materials are being asked for in the context of nuclear safety, minimisation of high level nuclear waste and safeguards and security. The different steps of my career development and the repeated process of managing learning, work, family and leisure are presented. The career path across different jobs and responsibilities and the career progress via a certification training programme are also explained to encourage the next generation of female professionals to continue playing a vital role in nuclear science and technology.

    The pre-treatment and handling techniques for the micro-particles in swipe samples were developed for the safeguards purpose. The development of screening technique for the swipe samples has been established using the nuclear fission track method as well as the alpha track method. The laser ablation system to take a nuclear particle present in swipe was designed and constructed for the determination of the enrichment factors for uranium or plutonium, and its performance was tested in atmosphere as well as in vacuum. The optimum conditions for the synthesis of silica based micro-particles were obtained for mass production. The optimum ion exchange resin was selected and the optimum conditions for the uranium adsorption in resin bead technique were established for the development of the enrichment factor for nuclear particles in swipe. The established technique was applied to the swipe taken directly from the nuclear facility and also to the archive samples of IAEA's environmental swipes. The evaluation of dose rate of neutron and secondary gamma-ray for the radiation shields were carried out to design the NIPS system, as well as the evaluation of the thermal neutron concentration effect by the various reflectors. D-D neutron generator was introduced as a neutron source for the NIPS system to have more advantages such as easier control and moderation capability than the {sup 252}Cf source. Simulated samples for explosive and chemical warfare were prepared to construct a prompt gamma-ray database. Based on the constructed database, a computer program for the detection of illicit chemical and nuclear materials was developed using the MATLAB software.

It has important applications in many areas of interest such as Reactor Monitoring and control, Accelerator based research, Laser and nuclear physics experiments, Health and environmental monitoring, Astrophysics experiments etc. It is a specialized field involving expertise in detection of radioactivity down to the level of few events per minute as well as processing and analysis of signals which can be as small as few hundred micro volts embedded in noise. Some applications involve digitizing and processing these signals with 0.001% accuracy and timing accuracies of a fraction of nano sec. Rapid developments in semiconductor related technologies have influenced the field of nuclear instrumentation. Development of FPGA's and ASIC's have made it possible to develop miniaturized smart and portable instruments for field applications. Advancements in field of computers, communications and various field buses have been successfully utilized for smart, portable and DSP based instrumentation. Smart sensor with detector and front-end electronics on a single silicon chip is now a reality. These instruments are also made intelligent by addition of fuzzy logic, artificial neural networks and expert systems. Electronics Division of BARC has made significant contribution to the field of nuclear instrumentation to achieve self-reliance in this area. This has also led to development of several new methods, which have been published in international journals and appreciated worldwide. As a step towards achieving complete self-reliance a programme for development of FPGA's, HMC's and ASIC's has been undertaken and is being followed with special emphasis. This also includes development of detector and front- end electronics on a single chip. This talk brings out details of these developments and describes the 'state of art' work done in India

    The substantial increase in global energy consumption in coming decades will be driven principally by the developing world. Although there is some awareness on both the technical and political levels of the advantages of nuclear power, it is not a globally favored option in a sustainable energy future. This paper, after discussion of rising energy consumption, concentrates on a comparison of the environmental impacts of the available energy options. (author)

    A number of borehole methods were used in the investigation of crystalline rocks at Whiteshell Nuclear Research Establishment and Chalk River Nuclear Laboratory in Canada. The selection of a crystalline-rock mass for the storage of nuclear waste likely will require the drilling and testing of a number of deep investigative boreholes in the rock mass. Although coring of at least one hole in each new area is essential, methods for making in-situ geophysical and hydrologic measurements can substitute for widespread coring and result in significant savings in time and money. Borehole-geophysical logging techniques permit the lateral extrapolation of data from a core hole. Log response is related to rock type, alteration, and the location and character of fractures. The geophysical logs that particularly are useful for these purposes are the acoustic televiewer and acoustic waveform, neutron and gamma, resistivity, temperature, and caliper. The acoustic-televiewer log of the borehole wall can provide high resolution data on the orientation and apparent width of fractures. In situ hydraulic tests of single fractures or fracture zones isolated by packers provide quantitative information on permeability, extent, and interconnection. The computer analysis of digitized acoustic waveforms has identified a part of the waveform that has amplitude variations related to permeabilities measured in the boreholes by packer tests. 38 refs., 37 figs., 4 tabs

    Every one knows that the TMI accident resulted from the defeat of the man-machine interfacing of main control room design and of the quality of the operators. So it is necessary to develop CNS which is very efficient to train operators, operation and maintenance supervisors, maintenance personnel and inspectors of regulation committee to uderstand the dynamic transient phenomena. The following are major parts of this projects: 1. Data collection and review. 2. Make into a contract for CNS with STUDSVIK. 3. Selection of malfunction. 4. Design of console panel and modification. 5. List up measuring instruments. We design and make CNS with STUDSVIK in Sweden, and install a simulator in Nuclear Training Center of KAERI not only for fundamental training of nuclear power plant, but also safety analysis by transient analysis and NSSS design.

    The development of a unique, bulk density, photoelectric cross section logging tool and its features is chronicled from conceptual infancy to initial field trials. A program for developing the Spectral Litho-Density (SLD) began in earnest with the construction of a four part test fixture. Studies, utilizing this fixture, were conducted to evaluate various source to detector spacings along with source and detector collimation angles. A broad range of formation densities, (1.688 to 3.107 grams/cc) and lithologies, (P/sub e/'s of 0.764 to 5.06 barns/electron), were assembled for these studies and for final tool characterization. Test fixture results reveal an optimum source to long space detector spacing with respect to formation density measurements. As well, it is shown the source collimator and its geometry play an important role in controlling the SLD density spine response. Further tests included the insertion of intermediate mudcakes, of varying thickness and density, between the tool pad face and borehole wall in order to appraise assorted tool designs. Upon completing the test fixture studies a set of prototype tools were assembled incorporating state-of-the-art design features. These features include beryllium encapsulated detectors for maximum P/sub e/ sensitivity, a beryllium windowed dewar flask (housing the detectors and photomultiplier tubes) for protection from hostile thermal logging conditions, and digitized long and short space spectra (256 channels/detector) for uphole gain stabilization and post processing benefits

    The objectives of this study are to develop the technology for the determination of isotopic ratios of nuclear particles detected from swipe samples and to develop the NIPS system. The R and D contents and results of this study are firstly the production of nuclear micro particle(1 ∼ 20 μm) and standardization, the examination of variation in fission track characteristic according to nuclear particle size and enrichment( 235 U: 1-50%), the construction of database and the application of this technique to swipe samples. If this technique is verified its superiority by various field tests and inter-laboratory comparison program with other institutes in developed countries, it can be possible to join NWAL supervised under IAEA and to export our technology abroad. Secondly, characteristics of alpha track by boron (n, α) nuclear reaction were studied to measure both total boron concentration and 10B enrichment. The correlation of number of alpha tracks and various 10B concentration was studied to evaluate the reliability of this method. Especially, cadmium shielding technique was introduced to reduce the background of alpha tracks by covering the solid track detector and the multi-dot detector plate was developed to increase the reproducibility of measurement by making boron solution dried evenly in the plate. The results of the alpha track method were found to be well agreed with those of mass spectroscopy within less than 10 % deviation. Finally, the NIPS system using 252 Cf neutron source was developed and prompt gamma spectrum and its background were obtained. Monte Carlo method using MCNP-4B code was utilized for the interpretation of neutron and gamma-ray shielding condition as well as the moderation of a fast neutron. Gamma-gamma coincidence was introduced to reduce the prompt gamma background. The counting efficiency of the HPGe detector was calibrated in the energy range from 50 keV to 10 MeV using radio isotope standards and prompt gamma rays of Cl for the

    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.

    To sustain decent environmental conditions, it is essential to contain the emission of greenhouse gases. to a great extent, this can be achieved by reducing the almost exclusive dependence of fossil fuels for producing electricity and by championing nuclear energy and the renewable, which in the end are the least contaminating. Specifically, operation of the European nuclear fleet avoids the yearly emission of 700 million tons of CO 2 to the atmosphere. The need to combat climate change is very serious and increasingly imminent, especially if we remember that the World Health Organization has said that climate change could eventually cause 300,000 deaths. The different social players are aware of the problem. In fact, the European Union's Cabinet of Ministers approved the post-kyoto Environmental Strategy, which underlines the need to reduce CO e missions by 80% by the year 2050. It seems obvious that, in the long run, technological research and development will be fundamental pieces in the battle against environmental change and in the effort to one day provide 2,000 million people with access to electricity.

    Most of the available literature on geophysical borehole logging refers to studies carried out in sedimentary rocks. It is only in recent years that any great interest has been shown in geophysical logging in boreholes in metamorphic and igneous rocks following the development of research programmes associated with geothermal energy and nuclear waste disposal. This report is concerned with the programme of geophysical logging carried out on the three deep boreholes at Altnabreac, Caithness, to examine the effectiveness of these methods in crystalline rock. Of particular importance is the assessment of the performance of the various geophysical sondes run in the boreholes in relation to the rock mass properties. The geophysical data can be used to provide additional in-situ information on the geological, hydrogeological and engineering properties of the rock mass. Fracturing and weathering in the rock mass have a considerable effect on both the design parameters for an engineering structure and the flow of water through the rock mass; hence, the relation between the geophysical properties and the degree of fracturing and weathering is examined in some detail.

    To meet energy needs and curb climate change, the number of reactors will continue to increase because more and more countries are going the need nuclear power. At present, there are 436 nuclear reactors in the world that produce 16% of the electricity, and another 48 units are under construction in all, 31 countries in the world use nuclear power to produce electricity, and some countries that do not have reactors, e.g. Poland and Italy, are seriously planning to include nuclear power in their energy mix. Global nuclear development is a reality; energy and environmental challenges have led to new support for nuclear power, which is a safe, stable emission-free source. (Author)

    2009-01-01

    The IAEA is at the forefront of international efforts to strengthen the world's nuclear security framework. The current Nuclear Security Plan for 2006-2009 was approved by the IAEA Board of Governors in September 2005. This Plan has three main points of focus: needs assessment, prevention, detection and response. Its overall objective is to achieve improved worldwide security of nuclear and other radioactive material in use, storage and transport, and of their associated facilities. This will be achieved, in particular, through the provision of guidelines and recommendations, human resource development, nuclear security advisory services and assistance for the implementation of the framework in States, upon request. The presentation provides an overview of the IAEA nuclear security human resource development program that is divided into two parts: training and education. Whereas the training program focuses on filling gaps between the actual performance of personnel working in the area of nuclear security and the required competencies and skills needed to meet the international requirements and recommendations described in UN and IAEA documents relating to nuclear security, the Educational Program in Nuclear Security aims at developing nuclear security experts and specialists, at fostering a nuclear security culture and at establishing in this way sustainable knowledge in this field within a State. The presentation also elaborates on the nuclear security computer based learning component and provides insights into the use of human resource development as a tool in achieving the IAEA's long term goal of improving sustainable nuclear security in States.

    Due to growing concerns over electricity demand, energy security, and climate change, numerous countries are considering the construction of new nuclear power plants. Most of these will be built in nations with existing nuclear power programs, but an increasing number of States have expressed serious interest in developing new nuclear power programs. These countries will be faced with many challenges in establishing the robust infrastructures necessary for the safe, secure, and safeguarded deployment of nuclear power. Fortunately, there is much a State can gain through cooperation with other States with more developed programs. By sharing information on previous experience and established best practices, an emerging nuclear energy State can benefit from the lessons learned by its partners. Through a broad range of civil nuclear cooperation, the United States is helping new entrants develop the sound infrastructure necessary to deploy nuclear power plants with the highest standards of safety, security, and nonproliferation

    A series of accidents and scandals in nuclear facilities made us not only importance of nuclear safety security again but also difference between technical safety and social relief at development promoting side further large. Then, it is at an actual state that in spite of being positioned at basic electric source as well, nuclear power generation is made further delay of its development without obtaining easy understanding of peoples as shown in difficulty of its new construction and location. Under such conditions, as the nuclear relatives have efforted development of its publicity actions earnestly, it seems to take some times to realize formation of peoples' agreements. Here was groped toward some future ways by reviewing traditional nuclear publicities, through nine articles such as subjects on future nuclear publicity, efforts to nuclear publicity as a manufacturer, a required approach based on 'negative national character', a network bound between women at source and consumption sites, friendliness to the earth and human beings, a promotive action of understanding toward relief recovery and new addition on nuclear power, a report on meeting of evaluation and investigation of the nuclear publicity, toward reconstruction of nuclear publicity strategy by the Tohoku Electric Power Co., Ltd., and development on publicity action of the Hokkaido Electric Power Co., Ltd.

    Domondon, D.B.

    The ushering of nuclear era in the Philippines with the construction of the PNPP-I (Philippine Nuclear Power Plant) necessitates the evolvement and use of nuclear standards as a tool for safety evaluation in the licensing process. The Department of Nuclear Regulation and Safeguards under the Philippine Atomic Energy Commission has as one of its responsibilities the establishment of regulatory standards to ensure safe operation of nuclear facilities. This article points out the needs for nuclear standards and the steps in standard development which involve an enormous amount of resources in terms of manpower, expertise and money. The staff of the Department of Nuclear Regulations and Safeguards (DNRS) does not intend to engage in the original development of standards; rather, it reviews standards in use elsewhere, specifically in the U.S. and adopts to local conditions.

    It is useful in discussing proliferation problems linked to nuclear power to examine the history of nuclear power in India and the development of her capacity to produce heavy water, fabricate fuel rods, and process spent fuel. The author presents the few published economic analyses of the role of nuclear energy in India's development, then discusses issues relating to the Non-Proliferation Treaty (NPT) from India's point of view. The chapter concludes with some proposals for making the NPT more attractive so that nonsignatories will reconsider their position. One step should be to instill greater confidence that scientists in nonweapons states will be able to pursue their research in nuclear physics and that their electricity planners will have access to nuclear technology if they find it economically viable. A dramatic step toward nuclear disarmament will be the voluntary renunciation of nuclear weapons by one or more of the weapons states. 18 references, 2 tables

    2000-01-01

    This article describes the advantages of nuclear energy for Japan. In 1997 the composition of the total primary energy supply (TPES) was oil 52.7%, coal 16.5%, nuclear 16.1% and natural gas 10.7%. Nuclear power has a significant role to play in contributing to 3 national interests: i) energy security, ii) economic growth and iii) environmental protection. Energy security is assured because a stable supply of uranium fuel can be reasonably expected in spite of dependence on import from abroad. Economic growth implies the reduction of energy costs. As nuclear power is capital intensive, the power generation cost is less affected by the fuel cost, therefore nuclear power can realize low cost by favoring high capacity utilization factor. Fossil fuels have substantial impacts on environment such as global warming and acid rain by releasing massive quantities of CO 2 , so nuclear power is a major option for meeting the Kyoto limitations. In Japan, in 2010 nuclear power is expected to reach 17% of TPES and 45% of electricity generated. (A.C.)

    Although the high safety standards of the nuclear industry mean that the risk of an accident is low, the magnitude of damage that could result to third parties from such an accident is considerable. It was thus recognised from the very inception of the nuclear power industry that a special legal regime would need to be established to provide for the compensation of victims of a nuclear accident. The ordinary rules of tort and contract law were simply not suited to addressing such a situation in an efficient and effective manner. (authors)

    1997-11-01

    Although there is an awareness on both the technical and political levels of the advantages of nuclear power, it is not a globally favoured option in a sustainable energy future. A sizeable sector of public opinion remains hesitant or opposed to its increased use, some even to a continuation at present levels. With various groups calling for a role for nuclear power, there is a need openly and objectively to discuss the concerns that limit its acceptance: the perceived health effects, the consequences of severe accidents, the disposal of high level waste and nuclear proliferation. This brochure discusses these concerns, and also the distinct advantages of nuclear power. Extensive comparisons with other energy sources are made

    Full text: BATAN (National Atomic Energy Agency of Indonesia) was established in 1964, and after the issuance of Law 10 of 1997 it become National Nuclear Energy Agency. During the last seven years, BATAN has suffered the loss of many of its valuable human resources due to the zero-growth policy of the government in recruiting new staffs. The uncertain future of nuclear power programme in Indonesia has also reduced the interest of young generation to study nuclear related subjects, resulting in the closing of several departments in universities that once offered nuclear sciences as subject of studies. These situations triggered management of BATAN to develop various efforts to keep nuclear knowledge exist and disseminate among BATAN itself, university students, and public as a whole. BATAN has in recent years established higher school of nuclear technology and organized various nuclear related training programmes, and also in cooperation with other governmental organizations establish nuclear zones, nuclear information centres and nuclear corners in public as well as in high school areas throughout Indonesia. All these efforts are aimed to transfer and preserve nuclear knowledge for the better future of the applications of nuclear science and technology in Indonesia. (author

    Developing nations use the nuclear plant option to satisfy important overall national development objectives, in addition to providing economical electric power. The relative importance of these two objectives changes as the nuclear program develops and the interim milestones are reached. This paper describes the three typical stages of nuclear power development programs. The first and the second generations are development phases with the third generation reaching self sufficiency. Examples are presented of European and Far East countries or regions which have reached of are about to step into the third generation phase of development. The paper concludes that to achieve the objective of a nuclear power self sufficiency, other than merely filling the need of economical electric power, a careful technology transfer plan must be followed which sets realistic and achievable goals and establishes the country as a reliable and technically competent member of the nuclear power industry.

    Korean nuclear Official Development Assistance (ODA) is established with support from institutes such as the Korea International Cooperation Agency (KOICA) and the Korea Atomic Energy Research Institute (KAERI). KOICA's grant aid mainly made through the activities including IAEA's training program, and KAERI currently runs the inter-regional education and training cooperation called Asian Network for Education in Nuclear Technology(ANENT) which aimed to achieve the goal of encouraging web based education training network via cooperation with IAEA. Yet now these programs are focusing more on assisting nuclear infrastructure rather than highlighting nuclear education and training. This paper aims to, first, do a self-evaluation about the Korean ODA policy; second, to study the transition of the international nuclear atmosphere; and third, by apprehending the trend of the subjects of Korean nuclear ODA policy, to discuss the overall appropriate trajectory of Korean nuclear ODA

    Computerized survival prediction in healthcare identifying the risk of disease mortality, helps healthcare providers to effectively manage their patients by providing appropriate treatment options. In this study, we propose to apply a classification algorithm, Contrast Pattern Aided Logistic Regression (CPXR(Log)) with the probabilistic loss function, to develop and validate prognostic risk models to predict 1, 2, and 5year survival in heart failure (HF) using data from electronic health records (EHRs) at Mayo Clinic. The CPXR(Log) constructs a pattern aided logistic regression model defined by several patterns and corresponding local logistic regression models. One of the models generated by CPXR(Log) achieved an AUC and accuracy of 0.94 and 0.91, respectively, and significantly outperformed prognostic models reported in prior studies. Data extracted from EHRs allowed incorporation of patient co-morbidities into our models which helped improve the performance of the CPXR(Log) models (15.9% AUC improvement), although did not improve the accuracy of the models built by other classifiers. We also propose a probabilistic loss function to determine the large error and small error instances. The new loss function used in the algorithm outperforms other functions used in the previous studies by 1% improvement in the AUC. This study revealed that using EHR data to build prediction models can be very challenging using existing classification methods due to the high dimensionality and complexity of EHR data. The risk models developed by CPXR(Log) also reveal that HF is a highly heterogeneous disease, i.e., different subgroups of HF patients require different types of considerations with their diagnosis and treatment. Our risk models provided two valuable insights for application of predictive modeling techniques in biomedicine: Logistic risk models often make systematic prediction errors, and it is prudent to use subgroup based prediction models such as those given by CPXR(Log

    In this work the author demonstrates that the nuclear option for increasing the maghrebian capacities for electrical power production can not be conceived, from the ethic and humane point of view, for only one maghrebian country because of both external and internal constraints and difficulties which mortgage the future of destitute population and future generations. It is essential to lead intensive studies in this field by maghrebian research workers not accepting blindly foreign preconceptions. However, as a prelimenary, it is advisable to wonder about the ethical value of nuclear option, avoiding the multiform domination misdeeds (e.g. cultural and strategic) that such a choice involves for the maghrebis. 184 refs.

    The problems of nuclear power in developing countries are different in nature but not less severe than in industrialized countries. So far, only five developing countries with market economies (Argentina, India, Korea, Pakistan, Taiwan) have nuclear power plants in operation with a combined net output of 2.2 GWe. Nuclear projects with a total capacity of 15 GWe are under construction in these and four other developing countries in Asia and Latin America (Brazil, Iran, Mexico, Philippines). It is expected that most of the future nuclear power installed in developing countries of Asia, Africa and Latin America will be in these countries which have overcome some of the problems of nuclear power.

    International Nuclear Information System (INIS)

    Reitsma, S. M. S.

    1998-01-01

    The development of nuclear installations to produce electricity led to the establishment of Nuclear Insurance Pools and the introduction of international Conventions on Third Party Liability. Nuclear Pools offer both Third Party Liability insurance, reflecting the Conventions' principles, and other insurance products. They are market-wide, providing a facility for participation by insurers who could not otherwise write the insurance for the particularly sensitive nuclear risk. All acceptances are for the net retention of each Member without recourse to individual reinsurance protection. Common account reinsurance is arranged with other Nuclear Pools all over the world. Thus, a transparency is created, which ensures the highest degree of reinsurance security and imposes a known finite limit to each participating insurer's commitment. Therefore, Pool-members are prepared to make a greater commitment to nuclear risks than would be case where they felt uncertain as regards their total exposure following a significant loss. (author)

    Nuclear technology is a highly specialised field that requires a variety of professionals. Nuclear engineers, statisticians, physicists, information technology professionals, analysts, policy makers, scientists and other professionals. Because of the variety of backgrounds, many young female professionals need training and professional development opportunities to become well rounded in these disciplines. There has been a rising awareness of the need for development of the women professionals across the international field of the nuclear industry. Due to growth and expansion of nuclear power worldwide, a strong community of skilled next generation women professionals is required. Developing women professionals to fill this challenging need can first be addressed by making university students and young female professionals already working in the industry aware of the nuclear community and the unique career opportunities it encompasses. Once the decision is made to pursue a career in the nuclear community, professional development opportunities are an essential building block to becoming a more effective member of the international nuclear community. Current opportunities available to be discussed include international training, internships and fellowships, graduate degrees and professional networks. Present needs and gaps in the current professional development offerings will be identified as well as suggested ways they can be filled. In conclusion, programmes still needed in support of the career development of the female professionals will be addressed. (author)

    In 2009 Estonia approved the National Development Plan for the Energy Sector, including the nuclear energy option. This can be realized by construction of a nuclear power plant (NPP) in Estonia or by participation in neighboring nuclear projects (e.g., Lithuania and/or Finland). Either option requires the availability of competent personnel. It is necessary to prepare specialists with expertise in all aspects related to nuclear infrastructure and to meet workforce needs (e.g. energy enterprises, public agencies, municipalities). Estonia's leading institutions of higher education and research with the support of the European Social Fund have announced in this context a new nuclear master's curriculum to be developed. The language of instruction will be English. (authors)

    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

  12. Developing Infrastructure for New Nuclear Power Programmes

    International Nuclear Information System (INIS)

    2011-09-01

    Many countries are interested in introducing or expanding nuclear energy programmes because they regard nuclear power as a clean and stable source of electricity that can help to mitigate the impact of climate change. However, the March 2011 accident at the Fukushima Daiichi nuclear power plant in Japan - caused by an earthquake and tsunami of unprecedented proportions - demonstrated that there is a constant need to improve global nuclear safety, despite the great progress made in the previous 25 years. A 'safety first' approach needs to become fully entrenched among nuclear power plant operators, governments and regulators everywhere. Safety first must also be the watchword for Member States considering the introduction of nuclear power. I believe that all IAEA Member States should have access to nuclear power if they wish to add it their energy mix. While it is up to each country to decide whether or not to opt for nuclear power, the IAEA has a key role to play in ensuring that the development of nuclear power programmes takes place in a safe, efficient, responsible and sustainable manner. The IAEA has developed guidelines and milestones to help countries work in a systematic way towards the introduction of nuclear power. Use of the 'Milestones' approach can increase transparency both within a country introducing nuclear power, and between it and other States. This brochure summarizes the services which the IAEA offers to Member States considering introducing nuclear power. These include advice on proper planning, building the required human resources and infrastructure, establishing legal and regulatory frameworks, and ensuring the highest standards of safety and security, without increasing proliferation risks. The IAEA offers independent know-how on the construction, commissioning, startup and operation of nuclear reactors. Through the Technical Cooperation programme, we provide targeted support to 'newcomer' countries in response to national development needs

    The need for stable and reliable energy supply was clearly illustrated by the Philippine experience of the last five years where the bleak energy supply situation caused massive losses in productivity. Indigenous energy resources even if exploited to full capacity is not sufficient to support the progress needed to give our growing population the quality of life it deserves. Important too is the fact that world energy resources especially oil and natural gas is estimated to last up to the first half of the next century. Thus the entry of nuclear power as a vital contributor to a safe, reliable, competitive and cost effective source of energy supply become a necessity. (author)

    Vietnam began to be interested in education and training on nuclear sciences and related subjects since the early 1960's. A department of Nuclear Physics and Engineering was established in 1970 at the Hanoi University of Technology (HUT), which is the biggest interdisciplinary technological education centre of the country. In Vietnam there are several institutions where exist programmes of education on nuclear sciences and nuclear engineering. But HUT has been being since 1970 the only institution that has underway programme of education on nuclear engineer degree. Although the Department was renamed and its education programme was adjusted, but the objectives of its education programme have been being followed without changes. These objectives are as follows: 1) To develop peaceful applications of atomic energy in Vietnam; 2) To train up engineers on nuclear instrumentation for supporting the first objective; and 3) To prepare initial manpower for introduction of Nuclear Power in Vietnam. Nuclear community of Vietnam is still not so large. Total number of its members increased until 1986, and then decreases up to now. Present average age of members of the community is of 45. In 15 coming years at least 500-700 young people must be educated on programmes on nuclear engineer degree and on nuclear bachelor degree. This is a very difficult task for a developing country such as Vietnam. From a point of view of development, the above-mentioned number is too small, and it must be much more. This makes the task much more difficult. In addition, education on nuclear engineering in the country at present is in a hard situation because of lacking in experienced people, as well as in teaching material and equipment, and, because of weakness of the education programme. So, it may be impossible to achieve success in realization of the task without a large and effective international cooperation in education on nuclear science and engineering. That is why the Asian Network for

    The selection of an igneous rock body for the disposal of nuclear fuel waste will likely require the drilling and testing of a number of deep investigative boreholes in the rock body. Although coring of at least one hole at each Research Area will be essential, methods for making in situ geophysical and hydrological measurements can substitute for widespread coring and result in significant savings in time and money. A number of borehole methods have been applied to the investigation of plutonic rocks at Whiteshell Nuclear Research Establishment and Chalk River Nuclear Laboratories in Canada

    The development of nuclear power for space use in nuclear thermal propulsion (NTP) systems will involve significant expenditures of funds and require major technology development efforts. The development effort must be economically viable yet sufficient to validate the systems designed. Efforts are underway within the National Aeronautics and Space Administration's (NASA) Nuclear Cryogenic Propulsion Stage Project (NCPS) to study what a viable program would entail. The study will produce an integrated schedule, cost estimate and technology development plan. This will include the evaluation of various options for test facilities, types of testing and use of the engine, components, and technology developed. A "Human Rating" approach will also be developed and factored into the schedule, budget and technology development approach.

    Business decisions relating to the electric power sector are a provincial responsibility in Canada. The federal government looks to the three nuclear utilities to manage their nuclear assets and maintain them in a way that maximizes their reliability, efficiency and overall performance. A significant development in Canada's nuclear sector in the past year was the Ontario Hydro Nuclear Asset Optimization Plan. Structural change in the North American electricity market is a major impetus for decisions regarding nuclear assets by Canada's electric power utilities. The Ontario government is now taking steps to introduce competition in the Ontario Electricity market. The province of New Brunswick, which has one reactor at Point Lepreau which supplies one-third of the province's electricity, is also taking measures to introduce competition in its electricity market.

    Nuclear emulsion is high sensitive photographic film used for detection of three-dimensional trajectory of charged particles. These trajectories are recorded as tracks consist of a lot of silver grains. The size of silver grain is about 1 μm, so that nuclear emulsion has submicron three-dimensional spatial resolution, which gives us a few mrad three-dimensional angular resolution. The important technical progress was speed-up of the read-out technique of nuclear emulsions built with optical microscope system. We succeeded in developing a high-speed three-dimensional read-out system named Super Ultra Track Selector (S-UTS) with the operating read-out speed of approximately 50 cm2/h. Nowadays we are developing the nuclear emulsion gel independently in Nagoya University by introducing emulsion gel production machine. Moreover, we are developing nuclear emulsion production technologies (gel production, poring and mass production). In this paper, development of nuclear emulsion technologies for the OPERA experiment, applications by the technologies and current development are described.

    25 years have passed since the first nuclear power plant in the Soviet Union started operation and thus laid the foundations for the development of a fundamentally new branch of economy - nuclear industry. At present the following nuclear power plants are operated in the Soviet Union: Belojarsk, Kola, Bilibino, Armenia, Leningrad, Kursk, and Tschernobylj, the number of power plant units amounting to 19, the total electric power to 0.09 GW. In total the plants have generated 44.8 billion kWh in 1978; for 1979 a total generation of 54 billion kWh is expected. By the following five-year plans the construction of nuclear power plants is to be still essentially extended: about 20% of the total electric power is planned to be produced by nuclear power plants. In the course of this extension the new nuclear power plants are planned to achieve individual capacities between 4 and 6 GW, the nuclear heating power plants 2 GW.

    In nuclear facilities, the nuclear material control is one of the most important activities. The Brazilian National Commission of Nuclear Energy (CNEN) and the International Atomic Energy Agency (IAEA), when inspecting routinely, regards the data provided as a major safety factor. Having a control system of nuclear material that allows the amount and location of the various items to be inspected, at any time, is a key factor today. The objective of this work was to enhance the existing system using a more friendly platform of development, through the VisualBasic programming language (Microsoft Corporation), to facilitate the operation team of the reactor IEA-R1 Reactor tasks, providing data that enable a better and prompter control of the IEA-R1 nuclear material. These data have allowed the development of papers presented at national and international conferences and the development of master's dissertations and doctorate theses. The software object of this study was designed to meet the requirements of the CNEN and the IAEA safeguard rules, but its functions may be expanded in accordance with future needs. The program developed can be used in other reactors to be built in the country, since it is very practical and allows an effective control of the nuclear material in the facilities. (author)

    This paper presents an attempt to depict the situation in the Armenian Nuclear Energy Sector with the particular focusing on its further development. Basing on the energy independence and national security strategy principles, the Government of Armenia made a decision to construct a new nuclear unit in the Republic to replace Unit 2 of the Armenian NPP after its decommissioning. The paper shows that the only acceptable way of electricity generation in Armenia is the combined operation of thermal power plants and new nuclear unit, with the use of domestic renewable energy sources. This will allow to cover the Republic's energy demand and to export the excess electricity to the neighboring countries

    China and India are expected to achieve the world's largest energy and electricity consumption because of population and economic growth. In the past, the two countries covered coal demand by domestic coal production, however, these countries have now turned to net importers. From the point of view of energy security improvement, the both countries are actively developing nuclear power. IEA expects that the nuclear power electricity ratio will be 10.4% in China and 6.5% in India in 2040. If it is converted to 1 GW class nuclear power plant, China and India must respectively start to operate 4.9 units and 1.2 units per year up to 2040. In the future, the two countries are expected to play the leading role of nuclear energy development. (author)

  8. Vadose zone monitoring plan using geophysical nuclear logging for radionuclides discharged to Hanford liquid waste disposal facilities

    Price, R.K.

    1995-11-01

    During plutonium production at Hanford, large quantities of hazardous and radioactive liquid effluent waste have been discharged to the subsurface (vadose zone). These discharges at over 330 liquid effluent disposal facilities (ie. cribs, ditches, and ponds) account for over 3,000,000 curies of radioactive waste released into the subsurface. It is estimated that 10% of the contaminants have reached the groundwater in many places. Continuing migration may further impact groundwater quality in the future. Through the RCRA Operational Monitoring Program, a Radionuclide Logging System (RLS) has been obtained by Hanford Technical Services (HTS) and enhanced to measure the distribution of contaminants and monitor radionuclide movement in existing groundwater and vadose zone boreholes. Approximately 100 wells are logged by HTS each year in this program. In some cases, movement has been observed years after discharges were terminated. A similar program is in place to monitor the vadose zone at the Tank Farms. This monitoring plan describes Hanford Programs for monitoring the movement of radioactive contamination in the vadose zone. Program background, drivers, and strategy are presented. The objective of this program is to ensure that DOE-RL is aware of any migration of contaminants in the vadose zone, such that groundwater can be protected and early actions can be taken as needed

    SWOT Analysis is a Useful tool that can he applied to most projects or business ventures. In this article we are going to examine major strengths, weaknesses, opportunities and threats of nuclear power plants in view of sustainable development. Nuclear power plants have already attained widespread recognition for its benefits in fossil pollution abatement, near-zero green house gas emission, price stability and security of energy supply. The impressive new development is that these virtues are now a cost -free bonus, because, in long run, nuclear energy has become an inexpensive way to generate electricity. Nuclear energy's pre-eminence economically and environmentally has two implications for government policy. First, governments should ensure that nuclear licensing and safety oversight arc not only rigorous but also efficient in facilitating timely development of advanced power plants. Second, governments should be bold incentivizing the transformation to clean energy economics, recognizing that such short-term stimulus will, in the case of nuclear plants, simply accelerate desirable changes that now have their own long-term momentum. The increased competitiveness of nuclear power plant is the result of cost reductions in all aspects of nuclear economics: Construction, financing, operations, waste management and decommissioning. Among the cost-lowering factors are the evolution to standardized reactor designs, shorter construction periods, new financing techniques, more efficient generation technologies, higher rates of reactor utilization, and longer plant lifetimes. U.S World Nuclear Association report shows that total electricity costs for power plant construction and operation were calculated at two interest rates. At 10%, midrange generating costs per kilowatt-hour are nuclear at 4 cents, coal at 4.7 cents and natural gas at 5.1 cent. At a 5% interest rate, mid-range costs per KWh fall to nuclear at 2.6 cents, coal at 3.7 cents and natural gas at 4.3 cents

    This report discusses the objective preconditions, which would lead the world community to acceptance of nuclear energy. The following conditions deserve special emphasis: (a) Demographic growth, resulting in the increase of energy demand and promoting the understanding of the fact, that the world energy resources are limited and all possible energy sources, including nuclear ones, should be used. (b) Development of the 'third-world' countries, creating additional energy demand, which cannot be met without nuclear power. (c) Global (and influencing the plans of each country) need of availability and acceptable costs together with reliability and safety of energy supply, and, consequently, the interest to energy sources diversification in order to eliminate the dependence of fossil fuels import. The paper considers the ways to solve this strategic task. Its solution could take a long time (several decades) and should be properly perceived by the generation of specialists now starting their career in nuclear science and industry. Now it is a good time for the new generation of nuclear specialists to solve this problem - the large-scale NPP development is not yet needed, there is a large accumulated experience and perspective ideas, and there is enough time to analyze the problems in detail, propose and prepare the solutions and convince the general public, that these solutions are correct. And then the next phase of nuclear energy development would be based not only on correct technical solutions, but also on a favourable social environment. (authors)

    Logging is one of the most hazardous occupations in the United States. Real-time positioning that uses global navigation satellite system (GNSS) technology paired with radio frequency transmission (GNSS-RF) has the potential to reduce fatal and non-fatal accidents on logging operations through the use of geofences that define safe work areas. Until recently, most geofences have been static boundaries. The aim of this study was to evaluate factors affecting mobile geofence accuracy in order to determine whether virtual safety zones around moving ground workers or equipment are a viable option for improving situational awareness on active timber sales. We evaluated the effects of walking pace, transmission interval, geofence radius, and intersection angle on geofence alert delay using a replicated field experiment. Simulation was then used to validate field results and calculate the proportion of GNSS error bearings resulting in early alerts. The interaction of geofence radius and intersection angle affected safety geofence alert delay in the field experiment. The most inaccurate alerts were negative, representing early warning. The magnitude of this effect was largest at the greatest intersection angles. Simulation analysis supported these field results and also showed that larger GNSS error corresponded to greater variability in alert delay. Increasing intersection angle resulted in a larger proportion of directional GNSS error that triggered incorrect, early warnings. Because the accuracy of geofence alerts varied greatly depending on GNSS error and angle of approach, geofencing for occupational safety is most appropriate for general situational awareness unless real-time correction methods to improve accuracy or higher quality GNSS-RF transponders are used.

  19. Acceptance of nuclear energy in developed countries

    This paper focuses on the presence of problems, governmental efforts and the state of each people's awareness in accepting nuclear energy especially in developed countries and reviews the past circumstances and recent activities. Significant differences among countries in the popularity of nuclear power depend largely on the environment of the particular country such as energy circumstances and also on the execution of the energy policy. Also it is pointed out that the difference comes from the consciousness of the execution of the people in such a policy they establish and decide whether they accept or not. The analysis, that the French people traditionally believe they cannot control risks and give high degree of trust to their government and specialists, whereas Americans conversely intervene in administration to control risks by themselves and try to change specialist's Judgment, explains one side of polarization in popularity of nuclear energy in the world. Japanese have tended to not to believe the administration probably due to recent continuous scandals of officials and motivation to require disclosure of information and to dispute, which lays on the background of retard of nuclear energy. For resolving the global issues such as warming, it is becoming more important that at least specialists of nuclear technology recover the loosing trust owing to the accidents and scandals through steady activities, show the whole view of trust worthy development plan of nuclear energy and regain the confidence by the people.

    Any discussion of 21st century energy trends must take into account the global energy imbalance. Roughly 1.6 billion people still lack access to modern energy services, and few aspects of development - whether related to living standards, health care or industrial productivity - can take place without the requisite supply of energy. As we look to the century before us, the growth in energy demand will be substantial, and 'connecting the unconnected' will be a key to progress. Another challenge will be sustainability. How can we meet these growing energy needs without creating negative side effects that could compromise the living environment of future generations? Nuclear power is not a 'fix-all' option. It is a choice that has a place among the mix of solutions, and expectations for the expanding use of nuclear power are rising. In addition to the growth in demand, these expectations are driven by energy security concerns, nuclear power's low greenhouse gas emissions, and the sustained strong performance of nuclear plants.

    For decades, India was a less developed economy among the Asian states. In the past few years, India's economy experienced a major increase in growth, its gross domestic product growing by an average of 8 percent. Also as a consequence of its geographic location and demographic as well as economic potentials, India has thus become a serious player on the international scene. The country's economic growth is associated with a rising energy requirement, which is viewed with growing concern by the international community because of the country's limited resources and because of the impact on world climate. The article describes and analyzes India's current economic development compared to other countries. Also the status and development goals of India's power industry are outlined, mainly under the headings of primary energy consumption and energy resources as well as the electricity economy. The main focus in the report is on the use of nuclear power in India, offering an analysis of the history of nuclear power development, a status quo report, and an outlook into the future program of major expansion plans of nuclear power. A structural description of the nuclear sector in India completes the report. The article was compiled mainly from sources of Indian government organizations and research establishments and concentrates exclusively on the civil uses of nuclear power. (orig.)

    The energy issue is now a worldwide concern. It is showed that nuclear energy combined with renewable energies are the only efficient response to face the challenge of climate warming by cutting drastically the emission of greenhouse gases in the electricity production. The second asset of nuclear energy is to be able to meet the growing need for electric power of developing countries. Energy conservation is a good thing to do in western countries but it is far to be sufficient. The success of France's nuclear energy program has enabled the country to be independent from other countries concerning its electricity production, to produce electricity at moderate and stable costs even on the long term, and to develop nuclear industry operators that are world leaders. According to the 28 june 2006 bill that clarifies the management of radioactive wastes, the disposal of high-level radioactive wastes in deep geological layers, will be put into service in 2025. The law has let the possibility of recovering the waste containers during a certain period after their burial if new solutions will have emerged. In the context of an expected renaissance of nuclear energy, the EPR (European Pressurized Reactor) is a valuable offer that must be developed. The construction of an EPR unit on the Flamanville site is necessary to perfect its design. (A.C.)

    During the last 50 years or so there is enormous development in various fields like agriculture, industry, medicine, etc. Further, the population on this globe has increased many folds. In order to cater to the needs of the present population there is an increasing demand of electricity in the society. Per capita electricity consumption also is an index of development in the country. Considering the facts like green house effect and global warming, nuclear energy is the better option. But at the same time there are some critical issues like nuclear waste management globally and availability of fissile material in the context of our country. Research and development are going on to take care of these issues where scientists and engineers are working on alternative fuel cycle and new reactor types, for example Accelerator Driven Subcritical (ADS) System is one of them. Since, ADS reactor is a subcritical system, safety related issues are in fact of low concern relative to existing critical reactors. As a matter of fact, the ADS system is the combination of a particle accelerator and a nuclear reactor. In this talk, a detailed description of the need of energy in our country, which can only be met if nuclear energy contributes a substantial energy requirement, will be presented. Further, how the nuclear waste management issues may be addressed, with the new ADS system will also be presented. (author)

    The demand for electricity in developing countries of the world is expected to grow rapidly in the coming decades as these countries undergo the process of industrialization, accompanied by increased urbanization, and seek to improve the living standards of their growing population. The continued heavy reliance of the power sector on fossil fuels will result in an increased dependence of a number of the developing countries on energy imports, with consequentbalance of payment difficulties and implications in terms of reduced energy security, cause severe degradation of the local and regional environment, and will also lead to increasing emissions of greenhouse gases. Increasing the share of hydropower in most of the developing countries is constrained by the limited potential of hydro resources as well as environmental considerations. Other renewable energy technologies such as solar PV and wind power are not expected to play a significant role in the commercial supply of electricity in the foreseeable future in the most part of the developing world. Thus nuclear power as a non-fossil alternative with a proven and mature technology may be called upon to play an increasing role in the future supply of electricity to developing countries. The paper discusses the main factors that are likely to affect, both positively and negatively, the deployment of nuclear power in developing countries and presents the results of the recent IAEA projections on nuclear power capacity growth up to the 2020. The paper also briefly reviews the prospects of nuclear power in Central and Eastern European countries. (author)

    France was affected largely by two oil shocks as the energy supply has depended mainly on imported petroleum similarly to Japan, but France and Japan have successfully dealt with energy problems. These two countries have taken the countermeasures required for getting rid of the risk due to the heavy dependence on petroleum exporting countries. By advancing nuclear power policy with resolution, France and Japan are successfully changing the situation. The progress during the past ten years in the establishment of the nuclear power industry in France is explained. In France, PWRs were selected, and the standardization of units was carried out. In the first stage, 34 reactors of 900 MW were to be constructed by dividing into three periods, and in the second stage, 18 reactors of 1300 MW were to be constructed in three periods. At present, the nuclear power plants of 23.9 million kW are in operation, and 11 plants are under construction. The nuclear power generation in France is sufficiently able to compete economically. In 1990, the PWR power stations will attain 50 million kW. The growth of electric power consumption slowed down recently, and it is the problem to maintain the fully developed nuclear power industry while reducing the growth rate of nuclear power generation. Energy should be used in the form of electric power. (Kako, I.)

    Scottish Nuclear has recently completed a major program of improvements to its nuclear emergency facilities. The improvements include the construction of a purpose built Off-Site Emergency Centre for each of its two power stations and the development of a computer based information management system to facilitate the rapid distribution of information on an emergency to local, regional and national agencies. A computer code has also been developed to allow the rapid assessment of the effects of any accidental release on the local population. The improvements to the emergency facilities have been coupled with changes in local and national arrangements for dealing with a civil nuclear emergency. The use of airborne surveying techniques for rapidly determining levels of deposited activity following an accident is also being examined and preliminary airborne surveys have been carried out.

    Remote tool systems to undertake nuclear dismantling operations require careful design and development not only to perform their given duty but to perform it safely within the constraints imposed by harsh environmental conditions. Framatome ANP NUCLEAR SERVICES has for a long time developed and qualified equipment to undertake specific maintenance operations of nuclear reactors. The tool development methodology from this activity has since been adapted to resolve some very challenging reactor dismantling operations which are demonstrated in this paper. Each nuclear decommissioning project is a unique case, technical characterisation data is generally incomplete. The development of the dismantling methodology and associated equipment is by and large an iterative process combining design and simulation with feasibility and validation testing. The first stage of the development process involves feasibility testing of industrial tools and examining adaptations necessary to control and deploy the tool remotely with respect to the chosen methodology and environmental constraints. This results in a prototype tool and deployment system to validate the basic process. The second stage involves detailed design which integrates any remaining technical and environmental constraints. At the end of this stage, tools and deployment systems, operators and operating procedures are qualified on full scale mock ups. (authors)

    Chinese President Xi Jinping addresses China's new concept of nuclear security with four 'equal emphasis' at the third Nuclear Security Summit, and makes four commitments to strengthen nuclear security in the future. To convert President Xi's political commitments into practical, sustainable reality, China should take further steps to install a complete, reliable, and effective security system to ensure that all its nuclear materials and nuclear facilities are effectively protected against the full spectrum of plausible terrorist and criminal threats. This paper suggests the following measures be taken to improve China's existing nuclear security system, including updating and clarifying the requirements for a national level DBT; updating and enforcing existing regulations; further promoting nuclear security culture; balancing the costs of nuclear security, and further strengthening international cooperation on nuclear security.

    Determination of the manpower required for implementation of a nuclear programme is a very important factor from the national viewpoint, as it is drawn from many sectors of industry. The author provides a case-study of manpower requirements in France. He is in favour of the establishment of a manpower programme within the educational system, involving schools and universities since technicians and engineers have an important role to play throughout the different stages of a nuclear programme. In this context, he describes the IAEA contribution to acquisition of know-how by means of training courses for developing countries. (NEA) [fr

    Morocco is on the way to developing and gaining access to advanced technologies which will allow it to take good advantage of its natural resources. Most of the fuels necessary for electricity production have to be imported. Nuclear energy appears a better alternative to imported oil or coal, mainly due to kWh price competitivness, great potential of uranium in phosphates and to the limitations placed on the coal option by harbour and transport infrastructure. The first nuclear power plant is planned to go into operation in the year 2000

    Various aspects of public opinion concerning nuclear power plants are discussed. Particular attention is paid to the reasons and objectives of antinuclear opposition, its forms and impacts. It is assumed that overall, antinuclear movement has caused a 10-15 years' delay in the development of nuclear power industry. In industrial countries the influence of antinuclear opposition will probably lose in importance, as documented by the results of recent referenda in some states of the USA. In East-European countries, on the other hand, the growing antinuclear movement will probably force discontinuation of the operation of 1st generation nuclear power plants (without containment) and bring about delay in the building of units under construction and postponing construction of designed units. However, combined with efforts to reduce the high energy demands of Czechoslovak national economy, this trend need not necessarily result in an economic catastrophe. (Z.M.)

    Rapid expansion of the successful CANDU reactor system offers immediate substitution for scarce oil and gas, combined with long-term security of energy supplies. A continuing large and vigorous R and D program on nuclear power is essential to achieve these objectives. The program, described here, consists of tactical R and D in support of the current CANDU reactor system, strategic R and D to develop and demonstrate advanced CANDU systems, and exploratory R and D to put Canada in a position to exploit any fusion opportunities. Two support activities, management of radioactive wastes and techniques to safeguard nuclear materials against diversion, although integral components of the nuclear power programs, are identified separately because they are currently of special public interest.

    The author of this contribution, who read a paper on the same subject on the evening he was appointed Honorary Member of the Kerntechnische Gesellschaft (KTG), has been continuously engaged in a wide variety of activities within the French Atomic Energy Commission, CEA, for the past 32 years and has been in charge of the French breeder program since the late fifties. His analysis of the nuclear power situation in France and his survey of problems and development goals therefore is not only based on expert knowledge, but also reflects the official French idea of the rank nuclear power in the French energy supply policy and in the French economy. It shows that the foreseeable pronounced slowdown, due to declining demand, in the expansion of the network of nuclear power plants - a slowdown at a high level of capacity - does not detract from the growing importance of nuclear power in France. The awareness exists that this program can be, and must be, continued in its subareas. The French Government is convinced that the nuclear option was the only possible choice and that having decided in favor of it will pay even more in the future than it does already. (orig.) [de

    Large wood (LW) is an important functional and structural component of forest stream ecosystems, regulating sediment storage and transport, consequently determining channel morphology, and as an important foundation for aquatic habitat. LW occurs as either individual pieces or in accumulations (log jams). Where individual pieces of LW affect the stream at a small scale, several bankfull widths, jams influence the stream on a much larger scale. The spatial extent of jam related effects on channel morphology vary, dependent upon the life stage of the jam. Temporal changes in jams have received relatively little attention in the literature. The development stage of a jam is associated with upstream channel aggradation and downstream degradation; this process reverses during a jam's deterioration phase. Carnation Creek, an 11 km2 watershed located on the west coast of Vancouver Island, provided a rare opportunity to examine both the spatial and temporal impacts of log jams on channel morphology. An understanding of these relationships will be developed through the analysis of changes in channel variables, such as channel dimensions, pattern, hydraulic characteristics, and morphology. These characteristics will be extracted from annual cross sectional surveys taken during 1971 - 1998.

    Developers of High Temperature Reactors (HTR) worldwide acknowledge that the main asset for market breakthrough is its unique ability to address growing needs for industrial cogeneration of heat and power (CHP) owing to its high operating temperature and flexibility, adapted power level, modularity and robust safety features. HTR are thus well suited to most of the non-electric applications of nuclear energy, which represent about 80% of total energy consumption. This opens opportunities for reducing CO 2 emissions and securing energy supply which are complementary to those provided by systems dedicated to electricity generation. A strong alliance between nuclear and process heat user industries is a necessity for developing a nuclear system for the conventional process heat market, much in the same way as the electronuclear development required a close partnership with utilities. Initiating such an alliance is one of the objectives of the EUROPAIRS project just started in the frame of the EURATOM 7. Framework Programme (FP7) under AREVA coordination. Within EUROPAIRS, process heat user industries express their requirements whereas nuclear industry will provide the performance window of HTR. Starting from this shared information, an alliance will be forged by assessing the feasibility and impact of nuclear CHP from technical, industrial, economical, licensing and sustainability perspectives. This assessment work will allow pointing out the main issues and challenges for coupling an HTR with industrial process heat applications. On this basis, a Road-map will be elaborated for achieving an industrially relevant demonstration of such a coupling. This Road-map will not only take into consideration the necessary nuclear developments, but also the required adaptations of industrial application processes and the possible development of heat transport technologies from the nuclear heat source to application processes. Although only a small and short project (21 months

  7. Nuclear power for under-developed areas

    International Nuclear Information System (INIS)

    1959-01-01

    In evaluating the needs of the less developed countries for nuclear power and in determining how and to what extent these needs can be met, the fundamental questions to be decided are: (a) to what extent can the total power needs of these countries be met by conventional (thermal and hydro) means, (b) in which sectors would it be immediately possible - from both technical and economic points of view - to generate power from nuclear energy, and (c) in which areas would it be imperative to resort to nuclear power in the immediate future. The IAEA Second General Conference recommended a survey of the nuclear power needs of the less developed countries, a study on a continuing basis of the technology and economics of small and medium power reactors suited to these countries, dissemination of the information obtained and assistance in training personnel in the technology and economic utilization of such nuclear stations. And on the basis of this recommendation, the Agency has initiated an integrated two-year programme of work for examining the possibilities of utilizing nuclear power in under-developed countries. In carrying out this programme, the Agency is seeking potentially promising cases in which nuclear energy can yield necessarily limited but early benefits. That would help an assessment of the technical and economic possibilities of small and medium reactors in specific situations. It would also enable under-developed countries to compare and ascertain whether nuclear energy can provide an early solution to some of their pressing power problems. The first three phases of IAEA's work programme are: (i) studies on the technical suitability of reactors with a power level of up to 50 mw; (ii) economic studies in regard to reactor systems, including a systematic analysis of power costs; and (iii) selection of characteristic situations that appear to favour utilization of nuclear power. A survey of special interest in this connexion will be carried out by an Agency

    Full text: Progress during the past quarter of a century in the development and medical uses of radioisotopes and radiopharmaceuticals, and the benefits derived from their applications have been outstanding. The World health Organization (WHO) has stated that 'Nuclear Medicine' is taken to embrace all applications of radioactive materials in diagnosis, treatment or in medical research, with the exception of the use of sealed radiation sources in radiotherapy. How did the term come into use? In 1951 the editorial board of the American Journal of Roentgenology and Radium therapy decided to express its special interest in the field by a change in the title of that journal. The words 'and Nuclear Medicine' were added. Nuclear medicine was first introduced in Mongolia in the year 1975; 31 March 1975 to be precise, when radioiodine uptake studies and radio isotope renogram were first introduced in the country. Simultaneously several other studies like liver scanning with Au-198 Sulfur colloid and Pancreas imaging with Se-75 methionine were also introduced using the newly installed single and dual probe scintillation detector system and the Hungarian rectilinear scanner. Prof. Dr. Peljee Onkhuudai, presently the head of nuclear medicine at the First State Central Hospital, was the prime mover of these initiatives. He was the first physician from Mongolia to be fully qualified in Nuclear Medicine in the year 1975. He had his education and training in nuclear medicine at the Karl-Marx-University, Leipzig in Germany. In the year 1982 Mongolia received its first gamma camera (a new Siemens Gamma camera-PHO-ZLC) as well as started its RIA facility through an IAEA Technical Cooperation Project. Hence from the year 1982 the Nuclear Medicine Department has been responsible for providing both in vivo and in vitro nuclear medicine services to the people of Mongolia including Radionuclide therapy. There has been a gradual expansion of the department with respect to personnel

    A diversity of energy resources, and of climatic and environmental conditions, has shaped the development of Canada's energy systems. By the early 1950s, a significant scientific base had been established for the development of heavy water-moderated, natural uranium-fuelled reactors. This combination of an existing scientific base and the need to provide economic alternative sources of electricity prompted a policy under which the federal crown corporation Atomic Energy of Canada Limited would lead the development of nuclear power on a cooperative basis with interested electrical utilities. The close working relationship of all the participants--design, research, project management, consultants, manufacturers, utilities and regulators--led to the success of the unique Canadian nuclear program.

    The fifth 'Generation IV International Forum (GIF), Policy Group Meetings' was held at the Zen-Nikku Hotel in Tokyo, on September 19-20, 2002, under participations of Abraham, Secretary of DOE in U.S.A., Columbani, Secretary of CEA in France, Fujiie, Chairman of CAE in Japan, Kano, Parliamental Minister of MIS in Japan, and so on. Ten nations entering GIF (Argentina, Brazil, Canada, France, Japan, Korea, South Africa, Switzerland, U.K., and U.S.A.) selected six next generation nuclear energy concepts for objects of international cooperative research and development aiming at its practice by 2030. These concepts applicable to not only power generation, but also hydrogen production, sea water purification, and so on, are sodium liquid metal cooled reactor (Japan), high temperature gas cooled reactor (France), Super-critical pressure water cooled reactor (SCWR: Canada), Lead metal cooled reactor (Switzerland), Gas cooled fast reactor (U.S.A.), and molten salts reactor. On the generation IV nuclear reactor systems aiming to further upgrade their sustainability, safety, economical efficiency, and nuclear non proliferation, the 'Plans on Technical Development' (Road-map) to decide priority of their R and Ds has been cooperatively discussed under frameworks of international research cooperation by the GIF members nations. Here were shared descriptions on nuclear fuel cycle as a remise of technical evaluation and adopted concepts by Japanese participants contributing to making up the Road-map. (G.K.)

    Since France has been compelled to free itself from the domination of oil, it has undertaken a nuclear programme capable of providing for nearly one third of its energy needs by 1990. Some years after the first oil crisis, a good part of the battle has already been won: 22 reactor units of 900 MW each have been connected to the grid and account for 40% of the electricity produced in France, while 12 other 900 MW units, together with the first 1300 MW units, are under construction. Nuclear power has thus become an industrial reality possessed of the tools appropriate for the whole fuel cycle, which has managed to cope with costs and meet deadlines, and has developed a safe and reliable product. With these positive results despite inevitable incidents the French nuclear industry has come of age. There are, however, handicaps which remain to be overcome: high investment costs, operating constraints and continuing doubt on the part of the public. The efforts deployed in these three spheres are beginning to bear fruit. As a result, implementation of the French nuclear programme is being continued, albeit at a slower rate, for the aim is no longer to replace oil by nuclear power as soon as possible, but rather to keep up with the rise in consumption. In pursuing its nuclear efforts, France will henceforth be stressing progress in terms of quality, which can still be achieved in terms of increased reliability (incorporation of feedback), better economic return (initiation of a new series known as ''N4''), easier operation (improvement of the man-machine interface) and also more independence. The ''frenchification'' of the light-water reactor has from the beginning been seen as one of the means of achieving this independence. This also applies to mastery of the whole fuel cycle. And finally, fast breeders represent the next stage

  13. Development Of The Nuclear Optical Penetration

    1984-10-01

    We have developed the nuclear optical penetration to be incorporated in the wall penetration of the shell to introduce a data transmission system using optical fibers into a nuclear power plant with a pressurized water reactor. Radiation-induced coloration in optical glass seriously affects transmission characteristics of optical fibers, whereas it has been revealed that the pure-silica core optical fiber without any dopant in the core has wide applicability in radiation fields thanks to its very low radiation-induced attenuation. The wall penetration of the shell should have airtightness and resistivity to heat, vibration, and pressure, let alone radiation, excellent enough to be invariable in data transmission efficiency even when subjected to severe environmental tests. The sealing modules of this newly developed nuclear optical penetration are hermetically sealed. The gap between the optical fiber rod (100 pm in core diameter and 5 mm in rod diameter) and stainless steel tube is sealed with lamingted glass layer. As the result of He gas leakage test, high airtightness of less than 10 cc/sec was achieved. No thermal deformation of the core was caused by sealing with laminated glass layer, nor was observed transmission loss. Then the sealiing modules were subjected to the irradiation test using 60 Co gamma ray exposure of 2 x 10 rads. Though silica glass layer supporting the fiber rod and sealing glass portion turned blackish purple, transparency of the fiber was not affected. Only less than 0.5 dB of connecting loss was observed at the connecting point with the optical fiber cable. The sealing modules were also found to have resistivity to vibration and pressure as excellent as that of existing nuclear electric penetrations. We expect the nuclear optical fiber penetration will be much effective in improving reliability of data transmission systems using optical fibers in radiation fields.

These include new scintillation materials, the way of detecting the scintillation light, and completely novel methods to detect gamma rays by means of semiconductor detectors. In addition to combined instrumentation that can be used for SPECT and PET, already in clinical use, combined scintigraphic and anatomic imaging devices are now becoming available, for example SPECT/CT or PET/CT. This review article describes the most important of the new components, part of which have already entered product development and part of which are still in the research phase.

    2014-01-01

    There are clear advantages of development of a Nuclear Thermal Rocket (NTR) for a crewed mission to Mars. NTR for in-space propulsion enables more ambitious space missions by providing high thrust at high specific impulse (approximately 900 sec) that is 2 times the best theoretical performance possible for chemical rockets. Missions can be optimized for maximum payload capability to take more payload with reduced total mass to orbit; saving cost on reduction of the number of launch vehicles needed. Or missions can be optimized to minimize trip time significantly to reduce the deep space radiation exposure to the crew. NTR propulsion technology is a game changer for space exploration. However, "NUCLEAR" is a word that is feared and vilified by some groups and the hostility towards development of any nuclear systems can meet great opposition by the public as well as from national leaders and people in authority. Communication of nuclear safety will be critical to the success of the development of the NTR. Why is there a fear of nuclear? A bomb that can level a city is a scary weapon. The first and only times the Nuclear Bomb was used in a war was on Hiroshima and Nagasaki during World War 2. The "Little Boy" atomic bomb was dropped on Hiroshima on August 6, 1945 and the "Fat Man" on Nagasaki 3 days later on August 9th. Within the first 4 months of bombings, 90- 166 thousand people died in Hiroshima and 60-80 thousand died in Nagasaki. It is important to note for comparison that over 500 thousand people died and 5 million made homeless due to strategic bombing (approximately 150 thousand tons) of Japanese cities and war assets with conventional non-nuclear weapons between 1942- 1945. A major bombing campaign of "firebombing" of Tokyo called "Operation Meetinghouse" on March 9 and 10 consisting of 334 B-29's dropped approximately1,700 tons of bombs around 16 square mile area and over 100 thousand people have been estimated to have died. The declaration of death is very

    The new issue (no. 11) of the IAEA publications series Safety Reports, devoted to the safety culture in nuclear engineering Safety culture development in the nuclear activities. Practical recommendations to achieve success, is analyzed. A number of recommendations of international experts is presented and basic general indicators of satisfactory and insufficient safety culture in the nuclear engineering are indicated. It is shown that the safety culture has two foundations: human behavior and high quality of the control system. The necessity of creating the confidence by the management at all levels of the enterprise, development of individual initiative and responsibility of the workers, which make it possible to realize the structural hierarchic system, including technical, human and organizational constituents, is noted. Three stages are traced in the process of introducing the safety culture. At the first stage the require,emts of scientific-technical documentation and provisions of the governmental, regional and control organs are fulfilled. At the second stage the management of the organization accepts the safety as an important direction in its activities. At the third stage the organization accomplishes its work, proceeding from the position of constant safety improvement. The general model of the safety culture development is considered [ru

    Nuclear power plays a very important role in the long-term energy policy of Czechoslovakia. Its development is directly linked to the development of a nuclear power complex which includes, in addition to nuclear power itself, a series of new special nuclear production processes. The nuclear power complex is a large and highly complex technological and socio-economic scheme whose establishment requires substantial structural changes in the national economy. Accordingly, it is important to consider the economics of nuclear power development and management in relation to the development of the nuclear complex as a whole. Such an approach helps to reveal the interrelationship between the development of nuclear power and the development of the national economy as a whole, and makes it possible to determine the factors limiting development and also to establish the general economic necessity of introducing nuclear power production and ways of actively affecting it.

    Research and development activities on advanced and innovative reactors are performed within a domestic programme and international initiatives. The ongoing New Nuclear Fission National Programme is synergic and complementary to the International Nuclear Energy Initiative (INERI) and EURATOM framework programmes and is managed by ENEA through a specific agreement signed in June 2007 by the Italian Ministry for Economic Development (MSE). The activities concern an integral advanced pressurised light-water-cooled reactor (IRIS nuclear power plant [NPP]) and several Generation-4. fast reactors: lead-cooled, very high temperature and sodium-cooled. A summary of the main results achieved in 2007 follows. In the framework of the INERI programme ENEA and other Italian organisations are involved in the design of the International Reactor Innovative and Secure (IRIS NPP), particularly in the design certification. An appropriate integral testing programme will be performed in the SPES-3 facility to be built at the SIET laboratories in Piacenza. The facility will be located inside the building of the decommissioned Emilia oil-fired power plant. Once erected, the facility will simulate IRIS at full height, full pressure and temperature, and with volumes and power scaled by factors of 1:100 and 1:150, respectively. The activity will be carried out in a collaboration with Oak Ridge National Laboratory (ORNL), USA under an international initiative concerning cooperation in the field of nuclear-related technologies of mutual interest. In 2007 activities were mainly devoted to the conceptual design of the SPES-3 facility, the development of SPES-3 nodalization and the seismic isolation analysis of the IRIS auxiliary building

    In this period of expectation and short term viewing, everyone has difficulties to draw long term perspectives. A positive global world vision of sustainable development gives confidence in the preparation of energy future in a moving international context. This presentation proposes to share such a long term vision inside which energy scenarios for nuclear development take their right place. It is founded on a specific analysis of an index of countries global development which is representative of a country efficiency. Human Development Index (HDI) is a composite international index recommended and calculated every year since 1990 by the United Nations Development Program (UNDP). This index is still very dependent of GNP, which ignores the disparities of revenues inside the country. That is why a Country Efficiency Index (CEI) has been defined to better represent the capacity of a country to utilize its resources for welfare of its inhabitants. CEI is a ratio of health and education levels to the capacity of the country to satisfy this welfare. CEI has been calculated for the 70 more populated countries of the world for the year 1997. CEI calculation has been also performed for European Countries, the United States, China and India on the period from 1965 to 1997. It is observed a growth of CEI. for France from 0.6 to 0.78, and from 0.7 to 0.85 for USA. In 1997, CEI of China was 0.46, and 0.38 for India. This index is a good tool to measure the progression of development of the countries and the related energy needs. Comparison of the evolutions of CEI of these different countries shows a similar positive trend with some delay between OECD countries and China or India. A positive scenario for the future is based on a similar curve for these developing countries with learning effect which produces development with less energy consumption. This simulation results however in energy needs that exceed fossil fuel today available resources in 2070. Ultimate fossil

    For an increasingly busy and geographically dispersed faculty, the Faculty of Medicine at the University of Southampton, United Kingdom, developed a range of Web-based faculty development modules, based on Kolb's experiential learning cycle, to complement the faculty's face-to-face workshops. The objective of this study was to assess users' views and perceptions of the effectiveness of Web-based faculty development modules based on Kolb's experiential learning cycle. We explored (1) users' satisfaction with the modules, (2) whether Kolb's design framework supported users' learning, and (3) whether the design principle impacts their work as educators. We gathered data from users over a 3-year period using evaluation surveys built into each of the seven modules. Quantitative data were analyzed using descriptive statistics, and responses to open-ended questions were analyzed using content analysis. Out of the 409 module users, 283 completed the survey (69.1% response rate). Over 80% of the users reported being satisfied or very satisfied with seven individual aspects of the modules. The findings suggest a strong synergy between the design features that users rated most highly and the key stages of Kolb's learning cycle. The use of simulations and videos to give the users an initial experience as well as the opportunity to "Have a go" and receive feedback in a safe environment were both considered particularly useful. In addition to providing an opportunity for reflection, many participants considered that the modules would enhance their roles as educators through: increasing their knowledge on various education topics and the required standards for medical training, and improving their skills in teaching and assessing students through practice and feedback and ultimately increasing their confidence. Kolb's theory-based design principle used for Web-based faculty development can support faculty to improve their skills and has impact on their role as educators

    French nuclear R and D is distributed between the main partners of the French nuclear program: CEA, the national R and D organization; EDF, the French utility owning and operating the plants; Framatome and Novatome, suppliers of PWR and FBR Nuclear Steam Supply Systems. These partners are linked by close relationships that define and implement the various R and D programs. For turbine hall equipment, electric installations, and instrumentation and control, Alsthom, major supplier of conventional equipment, has launched important R and D programs in close cooperation with EDF. These programs aim in particular at developing new technologies based for example on superconductivity and thermodynamic cycles, improving yields and operation, increasing component lifetime, and developing and setting up a new generation of less expensive, more powerfull and efficient equipment which is to be used in the N4 series, such as the Arabelle turbine and feed pumps without cavitation. In this article, a short survey is presented of the main applied R and D efforts in France for PWRs, FBRs and the fuel cycle

    The Nuclear Plant Analyzer (NPA) is being developed as the U.S. Nuclear Regulatory Commission's (NRC's) state of the art safety analysis and engineering tool to address key nuclear plant safety issues. The NPA integrates the NRC's computerized reactor behavior simulation codes such as RELAP5 and TRAC-BWR, both of which are well-developed computer graphics programs, and large repositories of reactor design and experimental data. Utilizing the complex reactor behavior codes as well as the experiment data repositories enables simulation applications of the NPA that are generally not possible with more simplistic, less mechanistic reactor behavior codes. These latter codes are used in training simulators or with other NPA-type software packages and are limited to displaying calculated data only. This paper describes four applications of the NPA in assisting reactor safety analyses. Two analyses evaluated reactor operating procedures, during off-normal operation, for a pressurized water reactor (PWR) and a boiling water reactor (BWR), respectively. The third analysis was performed in support of a reactor safety experiment conducted in the Semiscale facility. The final application demonstrated the usefulness of atmospheric dispersion computer codes for site emergency planning purposes. An overview of the NPA and how it supported these analyses are the topics of this paper

    The proposed Swedish nuclear waste project is not in line with the three principles of sustainable development. In some aspects, it is not even compatible with Swedish law and ought therefore not to be given a permit under present circumstances. In our view, a number of measures need to be taken to improve the likelihood that the waste repository will promote and not further jeopardise sustainable development. One obvious measure would be to follow the recommendations concerning polluter pays principle put forward by the 2004 governmental committee. Further, it can be credible argued that the focus of the present disposal process has not been to find the best site and method from environmental point of view. If the precautionary principle is to be applied (and Swedish law is to be followed), alternative methods and sites have to be examined to see if they could provide better long-term safety. Concerning method, there are options that deserve much more attention such as so called 'deep boreholes'. In this approach the nuclear waste is placed in deep boreholes at depths of 2-4 km. Studies show that the long-term environmental safety and the possibility of hindering intentional intrusion may improve using the deep borehole method. Regarding localisation, one option would be to avoid siting the repository on the coast, but in what is called a 'recharge area'. In such an area groundwater on a regional scale travels downwards into the bedrock and it may take 50 000 years for a release of radioactivity to reach the surface, compared to less than 100 years with a coastal siting. Evidently, there may be better methods and sites than those now proposed by the Swedish nuclear industry. These options must be examined in detail before a decision is taken to implement the KBS method at a coastal site. If such methods or sites are found better they have to be used in the first place. Improvements are also necessary when it comes to public participation. We believe it is possible

    After the first energy crisis, in France depended heavily on oil import, the broad lines of strategy were the improvement of efficiency in energy use, the diversification of energy sources and the development of domestic substitute energy sources. The energy conservation policy achieved in 1983 up to 35 million tons of oil equivalent saving. The coal and natural gas output in France decreased during the last ten years, but the national energy production covered 38.7 % of the national needs in 1983. This result is mainly due to the implementation of electro-nuclear program whose contribution to the total energy consumption was more than 17 % in 1983. In 10 reference years, 29 PWR units of 900 MWe and 17 PWR units of 1300 MWe have been launched, and 27 units of 900 MWe each have been commissioned. The power cost per kWh generated by nuclear energy remained about 2/3 of that by coal. The cumulative production of 900 MWe PWRs is already equivalent to 50 reactor-years at full power. The average availability of the units was 68 % in 1983, which showed that the problems have been solved. Also the state of nuclear fuel cycle in France, the trend of reactor improvement and the long term plan are explained. (Kako, I.)

    A critical enabling technology in the evolutionary development of nuclear thermal propulsion (NTP) is the ability to predict the system performance under a variety of operating conditions. Since October 1991, US (DOE), (DOD) and NASA have initiated critical technology development efforts for NTP systems to be used on Space Exploration Initiative (SEI) missions to the Moon and Mars. This paper presents the strategy and progress of an interagency NASA/DOE/DOD team for NTP system modeling. It is the intent of the interagency team to develop several levels of computer programs to simulate various NTP systems. An interagency team was formed for this task to use the best capabilities available and to assure appropriate peer review. The vision and strategy of the interagency team for developing NTP system models will be discussed in this paper. A review of the progress on the Level 1 interagency model is also presented

    A simple user-friendly menu-driven database management system pertinent to the Impact of Subsurface Drainage Systems on land and Water Conditions (ISLaW) has been developed for use in water logging and salinity management issues of drainage areas. This database has been developed by integrating four software viz; Microsoft Excel, MS Word, Acrobat and MS Access. The information in the form of tables and figures with respect to various drainage projects has been presented in MS Word files. The major data sets of various subsurface drainage projects included in the ISLaW database are: i) technical aspects, ii) groundwater and soil salinity aspects, iii) socio-technical aspects, iv) agro-economic aspects, and v) operation and maintenance aspects. The various ISLaW files can be accessed just by clicking at the Menu buttons of the database system. This database not only gives feedback on the functioning of different subsurface drainage projects with respect to above mentioned various aspects, but also serves as a resource document for these data for future studies at other drainage projects. The developed database system is useful for planners, designers and Farmers' Organizations for improved operation of existing as well as development of future drainage projects. (author)

    The nuclear technology base in a developing country is relatively much smaller compared to those in the industrialised countries. Thus, nuclear knowledge and its management are of great importance for those countries which are interested in nuclear technology but are still in the development phase. It is neither desirable nor possible to use imported nuclear technology as a black box. It is important for a developing country to acquire the ability for the safe and efficient operation of a nuclear facility such as a nuclear power plant. This should be done with maximum local participation and a sound institutional memory. (author)

But every time I need to do something with log4j I've never done before I find myself searching for examples of how to do whatever that is, and I don't usually have much luck. I believe the reason for this is that there is a not a great deal of useful information about log4j, either in print or on the Internet. The information is too simple to be of real-world use, too complicated to be distilled quickly (which is what most developers

    Full text: Current level of development of nuclear technology pushes future owners and users to address several important challenges at the very beginning of preparation for introduction of nuclear power programme including development of national expertise and technical competence for safe and secure use of nuclear technology and creation of national scientific and research infrastructure. However, many times national stakeholders involved into the development of nuclear power programmes act in separate information environments. This creates confusion and may result in delays of execution of a nuclear power programmes. A common environment in this case is important to ensure information exchange and collaborative work on nuclear power programme development. A common environment facilitates transfer, preservation and spread of nuclear knowledge to all stakeholders involved in a national nuclear power programme. Due to the long life cycle of nuclear power plants, strengthening and maintaining the effective management of knowledge and information over the entire life cycle for licensed nuclear facilities is imperative. This covers areas including design, construction, commissioning, operation and decommissioning, especially in newcomer countries and new builds. Nuclear knowledge infrastructure assumes this role and helps countries deciding to develop nuclear programmes ensure the safe and secure use of its nuclear power for national development. (author

    Countries entering nuclear power programs for the first time find that inadequate planning for the development of trained manpower is a critical factor in the success of their programs. This requires the early training of a team for the planning and acquisition effort to be followed by training for the supervision of construction. In addition, there is the more readily recognized training for operation. Typical manpower needs for such projects have been documented by the International Atomic Energy Agency. The basic academic training of engineers and scientists, which should be available within the country; advanced academic training, which is often secured in institutions abroad; specialized training abroad by international agencies; specialized training by the vendors of nuclear equipment; and the development of indigenous training. This paper outlines all of these avenues but will concentrate on the training available through international agencies and on the development of indigenous training capability

    The feasibility of using oil-well bore-hole logging techniques for assaying the carbonate content of a potential shot site has been investigated. The procedure makes use of the detection of the 4439-keV γ ray of carbon and the 6130-keV γ ray of oxygen produced by the inelastic scattering of 14-MeV neutrons in the bore-hole medium. For the needs of the containment program, a sensitivity of detection of CO 2 to less than or equal to 0.02 weight fraction must be achieved. Laboratory measurements indicate that only with considerable development effort could a tool be made that would come close to achieving this goal

    International Nuclear Information System (INIS)

    Shinohara, Yoshikuni

    1986-01-01

    Major technical problems in developing softwares for intelligent robots for future nuclear applications are explained briefly. In order that a robot can perform various kinds of complex works, it must be equipped with a high level of artificial intelligence which includes sensing functions such as visiual, auditory, tactile, proximity sensing, cognitive functions such as recognition of objects and understanding of working environment, decision-making functions such as work planning and control functions such as manipulator and locomotion controls. A large amount of various kinds of signals and informations must be processed with a high speed for an integrated control of these functions. It will be desirable that the computer program for controlling a robot which must run in a real-time will have a functionally hierarchical and distributed structure from the view point of software development. Parallel processing will be required from the view point of computation time. (author)

  14. Developing safety in the nuclear fuel cycle

    Brown, M.L.

    1996-01-01

    The nuclear fuel cycle had its origins in the new technology developed in the 1940s and 50s involving novel physical and chemical processes. At the front end of the cycle, mining, milling and fuel fabrication all underwent development, but in general the focus of process development and safety concerns was the reprocessing stage, with radiation, contamination and criticality the chief hazards. Safety research is not over and there is still work to be done in advancing technical knowledge to new generation nuclear fuels such as Mixed Oxide Fuel and in refining knowledge of margins and of potential upset conditions. Some comments are made on potential areas for work. The NUCEF facility will provide many useful data to aid safety analysis and accident prevention. The routine operations in such plants, basically chemical factories, requires industrial safety and in addition the protection of workers against radiation or contamination. The engineering and management measures for this were novel and the early operation of such plants pioneering. Later commissioning and operating experience has improved routine operating safety, leading to a new generation of factories with highly developed worker protection, engineering safeguards and safety management systems. Ventilation of contamination control zones, remote operation and maintenance, and advanced neutron shielding are engineering examples. In safety management, dose control practices, formally controlled operating procedures and safety cases, and audit processes are comparable with, or lead, best industry practice in other hazardous industries. Nonetheless it is still important that the knowledge and experience from operating plants continue to be gathered together to provide a common basis for improvement. The NEA Working Group on Fuel Cycle Safety provides a forum for much of this interchange. Some activities in the Group are described in particular the FINAS incident reporting system. (J.P.N.)

    The global expansion of nuclear energy will require international cooperation to ensure that nuclear materials, facilities, and sensitive technologies are not diverted to non-peaceful uses. Developing countries will require assistance to ensure the effective regulation, management, and operation of their nuclear programs to achieve best practices in nuclear nonproliferation. A developing nation has many hurdles to pass before it can give assurances to the international community that it is capable of implementing a sustainable nuclear energy program. In August of this year, the U.S. Department of Energy and the Ministry of Science and Technology of the Socialist Republic of Vietnam signed an arrangement for Information Exchange and Cooperation on the Peaceful Uses of Nuclear Energy. This event signals an era of cooperation between the U.S. and Vietnam in the area of nuclear nonproliferation. This paper will address how DOE is supporting the development of secure and sustainable infrastructures in emerging nuclear nations such as Vietnam

    2015-01-01

    Radiation shielding analysis and development for the Nuclear Cryogenic Propulsion Stage (NCPS) effort is currently in progress and preliminary results have enabled consideration for critical interfaces in the reactor and propulsion stage systems. Early analyses have highlighted a number of engineering constraints, challenges, and possible mitigating solutions. Performance constraints include permissible crew dose rates (shared with expected cosmic ray dose), radiation heating flux into cryogenic propellant, and material radiation damage in critical components. Design strategies in staging can serve to reduce radiation scatter and enhance the effectiveness of inherent shielding within the spacecraft while minimizing the required mass of shielding in the reactor system. Within the reactor system, shield design is further constrained by the need for active cooling with minimal radiation streaming through flow channels. Material selection and thermal design must maximize the reliability of the shield to survive the extreme environment through a long duration mission with multiple engine restarts. A discussion of these challenges and relevant design strategies are provided for the mitigation of radiation in nuclear thermal propulsion.

    It is predicted that the decommissioning of a nuclear power plant would happen in Korea since 2020 but the need of partial decommissioning and decontamination for periodic inspection and life extension still has been on an increasing trend and its domestic market has gradually been extended. Therefore, in this project we developed following several essential technologies as a decommissioning R and D. The measurement technology for in-pipe radioactive contamination was developed for measuring alpha/beta/gamma emitting nuclides simultaneously inside a in-pipe and it was tested into the liquid waste transfer pipe in KRR-2. And the digital mock-up system for KRR-1 and 2 was developed for choosing the best scenarios among several scenarios on the basis of various decommissioning information(schedule, waste volume, cost, etc.) that are from the DMU and the methodology of decommissioning cost estimation was also developed for estimating a research reactor's decommissioning cost and the DMU and the decommissioning cost estimation system were incorporated into the decommissioning information integrated management system. Finally the treatment and management technology of the irradiated graphites that happened after decommissioning KRR-2 was developed in order to treat and manage the irradiated graphites safely

    Nuclear Fuel Complex (NFC), established in early 70's for production of fuel for PHWRs and BWRs in India, has made several improvements in different areas of fuel manufacturing. Starting with wire-wrap type of fuel bundles, NFC had switched over to split spacer type fuel bundle production in mid 80's. On the upstream side slurry extraction was introduced to prepare the pure uranyl nitrate solution directly from the MDU cake. Applying a thin layer of graphite to the inside of the tube was another modification. The Complex has developed cost effective and innovative techniques for these processes, especially for resistance welding of appendages on the fuel elements which has been a unique feature of the Indian PHWR fuel assemblies. Initially, the fuel fabrication plants were set-up with imported process equipment for most of the pelletisation and assembly operations. Gradually with design and development of indigenous equipment both for production and quality control, NFC has demonstrated total self reliance in fuel production by getting these special purpose machines manufactured indigenously. With the expertise gained in different areas of process development and equipment manufacturing, today NFC is in a position to offer know-how and process equipment at very attractive prices. The paper discusses some of the new processes that are developed/introduced in this field and describes different features of a few PLC based automatic equipment developed. Salient features of innovative techniques being adopted in the area Of UO 2 powder production are also briefly indicated. (author)

    1978-10-01

    The inventigation of materials which could be used for fabricating elastomeric seals for geothermal well logging equipment is described. The seals were to be made either from a methylphenylcarborane-siloxane base gum stock, or from new fluoroelastomer compounds synthesized at Hughes Aircraft Company. A literature search was made to obtain data on carborane-siloxane polymers, synthesis routes for fluorinated elastomers and high temperature hydrolytic stability tests of elastomers. Information was obtained on the first two topics, but very little was available on hydrolysis testing. A number of compounds, based on carborane-siloxane, were formulated and cured. Compression set, hardness and shrinkage tests with postcure variations were made on the most promising formulations. A simple hydrolytic stability test at 275/sup 0/C (525/sup 0/F) and 830 psi was developed which indicated that both the carborane and siloxane bonds were easily broken after short exposure periods. Thermodynamic calculatons indicated that this result could be expected. Because of the agreement between empirical and theoretical data, work on the carborane-siloxanes was discontinued after approximately the first year. Synthesis efforts to produce a highly fluorinated elastomer based on perfluorolkylene oxide were continued through the entrie program. None of these routes produced a satisfactory elastomer.

    A scientific nuclear reactor was launched in 1961, and a critical test assembly - in 1965. A unique gamma-ray source was created, and it was proposed to form an industrial production plant of radiation chemistry at Ignalina NPP. In order to supply Latvia with electricity, a site was chosen in the 1980-ties for a base-power nuclear power plant. After the restoration of independence the scientists of Latvia continue taking part in international projects of nuclear fusion and the 4th generation nuclear reactors. The supply of Latvia with electricity in a more distant period will be possible by using nuclear energy.

    The objective of this thesis was to develop a proton precession magnetometer for geophysical prospecting and base stations. The proton procession magnetometer measures the total magnetic fields intensity. It operates on the basis of nuclear magnetic resonance by determining the processing frequency of protons of a non viscous liquid in the terrestrial magnetic fields. The instrument was tested in field to evaluate signal/noise ratio, supportable gradient and battery consumption. Application test was carried out to take diurnal variation data and, reconnaissance and detail surveys data on an archaeological site in the Marajo Island-Pa. The test results were confronted with two commercial magnetometers-GP-70, McPhar e G-816, Geometric - and, with data from Observatorio Magnetico Ilha de Tatuoca as well. For all cases, the data comparison showed a good performance of the magnetometer tested. (author)

    In embarking on a joint approach in the supply of power, Framatome and Siemens agreed in 1989 to combine their future reactor development activities and, for this purpose, founded Nuclear Power International as a joint subsidiary. Their point project is called European Pressurized Water Reactor, and its conceptual design concept was defined in 1991. The 'harmonization phase' completed in 1992 adapted the concept to the national requirements in each of the two countries. At present, the budget is being drawn up, and the basic design is to be completed by 1995. The German and French safety organizations, GRS and IPSN, accompany the project; the German-French Directorate defines the safety standards. However, the scheme for bilatral cooperation can succeed only if Germany is able to achieve consensus on energy policy. (orig.) [de

    2007-01-01

    This paper illustrates the changing role of water chemistry in current operation of nuclear power plants. Water chemistry was sometimes perceived as the cause of materials problems, such as denting in PWR steam generators and intergranular stress corrosion cracking in BWRs. However, starting in the last decade, new chemistry options have been introduced to mitigate stress corrosion cracking and reduce fuel performance concerns. In BWRs and PWRs alike, water chemistry has evolved to successfully mitigate many problems as they have developed. The increasing complexity of the chemistry alternatives, coupled with the pressures to increase output and reduce costs, have demonstrated the need for new approaches to managing plant chemistry, which are addressed in the final part of this paper.

    1993-01-01

    Arms controllers have long complained that the only weapons states give up in arms control negotiations are strategically insignificant weapons. This is why the United States and Soviet Union shied away from giving up much in SALT I and SALT II: each side felt that it could not significantly reduce its nuclear forces, or take any step that might give the other side an advantage. Do not be fooled: policy makers in Washington and Moscow still believe that it is important to hang on to strategically significant weapons. But, because the world has changed in fundamental ways, fewer weapons are strategically significant today. Now that extended deterrence requirements have virtually disappeared, the main reason for having nuclear weapons is to deter other nuclear powers from attacking with their nuclear weapons. There is, therefore, no compelling reason for having large nuclear forces. Given concerns about unauthorized attacks, accidental launches, and high levels of defense spending, there are good reasons for deploying smaller forces. This is why Washington and Moscow have been cutting their nuclear arsenals to levels that were unimaginable even in 1990. How far this process will go is impossible to say at this juncture. What is clear is that Washington and Moscow can - and should - make even deeper cuts in their nuclear forces. If the United States and Russia retain arsenals with thousands of nuclear weapons, Britain, France, and China - whose arsenals contain hundreds of nuclear weapons - will not join the arms reduction process. Countries that have promised to give up the nuclear weapons currently stationed on their territory - Kazakhstan, the Ukraine, and Belorussia - will be more inclined to retain them, on the grounds that nuclear weapons are seen to have strategic and political value. For the same reasons, countries on the nuclear threshold, such as India, will be more inclined to acquire nuclear weapons. If the United States and Russia retain massive nuclear

    In May 2007 the South African Cabinet approved a National Hydrogen and Fuel Cell Technologies R and D and Innovation Strategy. The strategy will focus on research, development and innovation for: i) wealth creation through high value-added manufacturing and developing platinum group metals catalysis; ii) building on the existing knowledge in high temperature gas-cooled reactors (HTGR) and coal gasification Fischer-Tropsch technology, to develop local cost-competitive hydrogen production solutions; iii) to promote equity and inclusion in the economic benefits from South Africa's natural resource base. As part of the roll-out strategy, the South African Department of Science and Technology (DST) created three Competence Centres (CC), including a Hydrogen Infrastructure Competence Centre hosted by the North-West University (NWU) and the Council for Scientific and Industrial Research (CSIR). The Hydrogen Infrastructure CC is tasked with developing hydrogen production, storage, distribution as well as codes and standards programmes within the framework of the DST strategic objectives to ensure strategic national innovation over the next fifteen years. One of the focus areas of the Hydrogen Infrastructure CC will be on large scale CO 2 free hydrogen production through thermochemical water-splitting using nuclear heat from a suitable heat source such as a HTGR and the subsequent use of the hydrogen in applications such as the coal-to-liquid process and the steel industry. This paper will report on the status of the programme for thermochemical water-splitting as well as the associated projects for component and technology development envisaged in the Hydrogen Infrastructure CC. The paper will further elaborate on current and future collaboration opportunities as well as expected outputs and deliverables. (authors)

    Many countries have decided nuclear power for next energy resources as one of the long-term energy supply options. IAEA projected nuclear power expansion up to 2030 reaching between 447 GWe and 691 GWe compared to 370 GWe and 2660 TWh at the end of 2006. Both low and high projection is accompanied with new nuclear power plant constructions respectively 178 and 357, about 11 units per year, and most new construction is in North America, the Far East, Eastern Europe, the Middle East, and Southeast Asia. During the last forty years, thirty three countries have established commercial nuclear power programs but only some of them have developed comprehensive and large scale peaceful nuclear power infrastructure. Although various cooperation and guidance program of nuclear power infrastructure, developing appropriate environment and infrastructure of nuclear power plant is still challenging problems for developing countries launching nuclear power program. With increasing the demand of safety and safeguard from international society, creating appropriate infrastructure becomes essential requirements in national nuclear power program. In the viewpoint of developing countries, without sufficient explanation and proper guidance, infrastructure could be seen only as another barrier in its nuclear power program. The importance of infrastructure development would be obscured by ostensible business and infrastructure program can result in increasing entering barriers to peaceful nuclear power application field without benefits to developing countries and international community. To avoid this situation by providing enough explanation and realistic case example and cooperate with the countries wanting to establish comprehensive nuclear power infrastructure in the peaceful applications, we are creating the education program of infrastructure development with basic guidelines of the IAEA infrastructure series and Korean experiences from least developed country to advanced country

    Today the applications of nuclear physics span a very broad range of topics and fields. This review discusses a number of aspects of these applications, including selected topics and concepts in nuclear reactor physics, nuclear fusion, nuclear non-proliferation, nuclear-geophysics, and nuclear medicine. The review begins with a historic summary of the early years in applied nuclear physics, with an emphasis on the huge developments that took place around the time of World War II, and that underlie the physics involved in designs of nuclear explosions, controlled nuclear energy, and nuclear fusion. The review then moves to focus on modern applications of these concepts, including the basic concepts and diagnostics developed for the forensics of nuclear explosions, the nuclear diagnostics at the National Ignition Facility, nuclear reactor safeguards, and the detection of nuclear material production and trafficking. The review also summarizes recent developments in nuclear geophysics and nuclear medicine. The nuclear geophysics areas discussed include geo-chronology, nuclear logging for industry, the Oklo reactor, and geo-neutrinos. The section on nuclear medicine summarizes the critical advances in nuclear imaging, including PET and SPECT imaging, targeted radionuclide therapy, and the nuclear physics of medical isotope production. Each subfield discussed requires a review article unto itself, which is not the intention of the current review; rather, the current review is intended for readers who wish to get a broad understanding of applied nuclear physics.

    1996-01-01

    Whilst general public accepts the operation of western designed nuclear power stations as safe, waste management and decommission still figure as open problems, although such views are not in agreement with technical and economic status of these operations. A concern with imagined problems can have the effect of neglecting the real ones. In considering the long term development of nuclear energy the real problems can be associated with the wide use of plutonium and multiplication of national reprocessing and enrichment installations. Nuclear proliferation safety could be retained and developed through establishment of international nuclear fuel centres. Their operation would be particularly beneficial for small or medium nuclear countries. Several arguments are given why it is not premature to initiate a study which would identify and analyze the problems of establishing an international nuclear fuel centre. Central Europe could be a region which could be served by one of such nuclear fuel centres. (author)

    Healthy, coordinated development of nuclear energy in the Asia-Pacific region requires the securing of human resources. This is an important component of development and should be well designed in advance, notwithstanding the fact that each country and area has its own unique system for nuclear research, education, and training. Differences are even more pronounced where preparedness for nuclear abnormal occurrences are concerned, despite the international impact of such incidents. From this point of view, we examine the current situation in international education and training of nuclear specialists, encompassing nuclear education and training systems, IAEA efforts, bilateral and multilateral transregional cooperation, and matters relating to national and transnational preparedness for nuclear abnormal occurrences. We present a proposal to create a regional center that would establish cooperation in nuclear research, education, training, and preparedness for abnormal occurrences. (author)

    1994-01-01

    The reintroduction of nuclear power in the Philippines is favored by several factors such as : the inclusion of nuclear energy in the energy sector of the science and technology agenda for national development; the large gap between electricity demand and available local supply for the medium-term power development plan; the relatively lower health risks in nuclear power fuel cycle systems compared to the already acceptable power systems; the lower environmental impacts of nuclear power system compared to fossil fuelled systems and the availability of a regulatory framework and trained personnel who could form a core for implementing a nuclear power program. It is estimated that the electricity supply gap of 9600 MW for the period 1993-2005 could be partly supplied by nuclear power. The findings of a recent study are described, as well as the issues that have to be addressed in the reintroduction of nuclear power. 6 refs

    Neutron yields from 19 F(α,n) 22 Na reaction of uranium neutron interaction with uranium-bass materials, and the characteristics of shielded neutron assay probe have been studied. On the basis of the above examination, U-235 enrichment in UF 6 cylinders like model 30B and model 48Y was measured by the reaction and U-235 contents in the containers by non-destructive total passive neutron assay method. Total measurement efficiency as a result was found to be 6.44 x 10 -4 and 1.25 x 10 -4 for model 30B and model 40Y UF 6 cylinder, respectively. The uncertainty of measured enrichment as compared to Tag value obtained from chemical analysis approached about 5 % of relative error at 95 % confidence interval. In the follow-up action for the previously developed (1988) computer system of nuclear material accounting the error searching and treatment routine in accordance with code 10, of IAEA and respective facility attachment has been added to easing the burden of manual error correction by operator. In addition, the procedure for LEMUF calculation has been prepared to help bulk facility operators evaluating MUF in the period of material balance. (author)

    The author gives a brief survey on the short, but relatively successful story of nuclear energy in the Federal Republic of Germany (FRG). Like many other countries, FRG had to go through a very difficult period of political indecision and violent opposition from antinuclear groups, supported by large parts of the media. The licensing procedures have been streamlined, nuclear power plants are being built without major interference, and the FRG is making good progress in closing the fuel cycle. This means that nuclear power will play an important role in the energy supply system, although on a lower level than originally anticipated

    Declining natural resources, rising oil prices, looming climate change and the introduction of nuclear energy partnerships, such as GNEP, have reinvigorated global interest in nuclear energy. The convergence of such issues has prompted countries to move ahead quickly to deal with the challenges that lie ahead. However, developing countries, in particular, often lack the domestic infrastructure and public support needed to implement a nuclear energy program in a safe, secure, and nonproliferation-conscious environment. How might countries become ready for nuclear energy? What is needed is a framework for assessing a country's readiness for nuclear energy. This paper suggests that a Nuclear Energy Readiness Indicator (NERI) Index might serve as a meaningful basis for assessing a country's status in terms of progress toward nuclear energy utilization under appropriate conditions. The NERI Index is a benchmarking tool that measures a country's level of 'readiness' for nonproliferation-conscious nuclear energy development. NERI first identifies 8 key indicators that have been recognized by the International Atomic Energy Agency as key nonproliferation and security milestones to achieve prior to establishing a nuclear energy program. It then measures a country's progress in each of these areas on a 1-5 point scale. In doing so NERI illuminates gaps or underdeveloped areas in a country's nuclear infrastructure with a view to enable stakeholders to prioritize the allocation of resources toward programs and policies supporting international nonproliferation goals through responsible nuclear energy development. On a preliminary basis, the indicators selected include: (1) demonstrated need; (2) expressed political support; (3) participation in nonproliferation and nuclear security treaties, international terrorism conventions, and export and border control arrangements; (4) national nuclear-related legal and regulatory mechanisms; (5

    through air travel, industry out sourcing, and intangible channels of communication such as the Internet. Simply put, as international borders become more porous as a result of free-trade arrangements, opportunities for proliferators multiply as well. Although the collection of information and intelligence to aid nonproliferation has become easier in a more open and transparent trade environment, efforts to stem proliferation have become more difficult as the means of acquiring and transporting nuclear and other WMD-related technologies have also multiplied. As these examples suggest, existing nonproliferation tools and export control mechanisms are not up to the task of dealing with new global economic realities. IAEA Director noted recently: 'The relative ease with which a multinational illicit network could be set up and operated demonstrates clearly the inadequacy of the present export control system.' Nor is it likely -absent substantial support from authorities in developing countries around the globe - that all of today's new proliferation channels can be effectively plugged. What is needed, therefore (and has long been recognized as essential by nonproliferation advocates) is a universal norm supporting nonproliferation. But how can this goal be achieved? As with much of today's discussion about globalization, the answer may lie in China. A credible proliferation control system is viewed in Beijing as a prerequisite to China becoming a high-tech economy. China also could play a more critical role in promoting international cooperative nonproliferation activities. It is incumbent even more so, however, on the international community to recognize, promote, and engage efforts by China and other developing States to institute improved trade controls, even though these are made in the countries' own national self interest. In this endeavor, the interests of the international community and the state intersect. Support for such activities should be given high priority in

    Nuclear power is a proven technology which currently contributes about 16% to the world electricity supply and, to a much lesser extent, to heat supply in some countries. Nuclear Power is economically competitive with fossil fuels for base load electricity generation in many countries, and is one of the commercially proven energy supply options that could be extended in the future to reduce environmental burdens, especially greenhouse gas emissions, from the electricity sector. Over the past five decades, nearly ten thousand reactor-years of operating experience have been accumulated with current nuclear power plants. However, nuclear power is currently at a cross-road. There are no new nuclear power construction projects in most parts of the world, except some countries in East Asia and Eastern Europe. The main issues are economic competitiveness with cheap gas plants and public concerns on nuclear waste disposal and safety. Strong economic growth and the shrinking of existing electricity over-capacities could favour nuclear power. Since nuclear power emits no greenhouse gases to the environment, its development could be further accelerated by a breakthrough in innovative nuclear reactor technology development. Great attention also needs to be paid to the design of new nuclear reactors, which are modularized and faster to construct, thus reducing capital investment and construction period, and thereby improving their overall economics and their compatibility with the infrastructure of, in particular, developing countries, where new energy demands are expected. This paper discusses the future world energy outlook, challenges for and progresses on nuclear power; overview of new nuclear reactor technology development; and the role of the International Atomic Energy Agency (IAEA) in the development of new innovative nuclear reactors.

    Korea has become a technically independent nuclear country and has grown into an exporter of nuclear technologies. Thus, nuclear facilities are increasing in significance at KAERI (Korea Atomic Energy Research Institute), and it is time to address the nuclear safety. The importance of nuclear safety cannot be overemphasized. Therefore, a management system is needed urgently to manage the safety of nuclear facilities and to enhance the efficiency of nuclear information. We have established ISP (Information Strategy Planning) for the Integrated Information System of nuclear facility and safety management. The purpose of this paper is to develop a management system for nuclear safety. Therefore, we developed the Advanced Nuclear Safety Information Management system (hereinafter referred to as the 'ANSIM system'). The ANSIM system has been designed and implemented to computerize nuclear safety information for standardization, integration, and sharing in real-time. Figure 1 shows the main home page of the ANSIM system. In this paper, we describe the design requirements, contents, configurations, and utilizations of the ANSIM system

    King, F.

    2002-01-01

    This paper describes recent developments in the field of nuclear waste management in Canada with a focus on management of nuclear fuel waste. Of particular significance is the April 2001 tabling in the Canadian House of Commons of Bill C-27, An Act respecting the long-term management of nuclear fuel waste. At the time of finalizing this paper (January 15, 2002), Bill C-27 is in Third Reading in the House of Commons and is expected to move to the Senate in February. The Nuclear Fuel Waste Act is expected to come into force later in 2002. This Act requires the three nuclear utilities in Canada owning nuclear fuel waste to form a waste management organization and deposit funds into a segregated fund for nuclear fuel waste long-term management. The waste management organization is then required to perform a study of long-term management approaches for nuclear fuel waste and submit the study to the federal government within three years. The federal government will select an approach for implementation by the waste management organization. The paper discusses the activities that the nuclear fuel waste owners currently have underway to prepare for the formation of the waste management organization. As background, the paper reviews the status of interim storage of nuclear fuel waste in Canada, and describes previous initiatives related to the development of a national strategy for nuclear fuel waste long-term management

    Hydrophobicity has proven to be an extremely useful parameter in small molecule drug discovery programmes given that it can be used as a predictive tool to enable rational design. For larger molecules, including peptoids, where folding is possible, the situation is more complicated and the average hydrophobicity (as determined by RP-HPLC retention time) may not always provide an effective predictive tool for rational design. Herein, we report the first ever application of partitioning experiments to determine the log D values for a series of peptoids. By comparing log D and average hydrophobicities we highlight the potential advantage of employing the former as a predictive tool in the rational design of biologically active peptoids. © 2017 The Authors PEPSCI Published by Wiley Periodicals, Inc.

    For more than a half a century nuclear medicine is contributing in the field of medicine. Still nuclear medicine is not widely available in many countries. Especially in developing countries due to many a reasons nuclear medicine could not flourish in that way. Availability of radioisotope, high cost of instrument and sophistication of the branch are the three main reasons behind. Even the countries where nuclear medicine is functioning for quite a long time, the facilities for proper function are still not adequate. Training of manpower, maintenance of instruments, regular supply of isotopes and kit and cost effectiveness are some of the major problems. We have seen some fast developments in nuclear medicine in last few decades. Development of gamma detecting systems with SPECT, positron emission detector (PET), supported computer technology and introduction of some newer radiopharmaceuticals for functional studies are few of the examples. The developing countries also have a problem to go on parallel with these rapid development of nuclear medicine in other part of the world. In last few decades we have also witnessed development of CT, MRI, Ultrasound and other imaging modalities as our competitor. Specially for developing countries these have posed as a major challenge for nuclear medicine. A better understanding between developed and developing nations is the key point of todays ultimate success in any sector. For real development of nuclear medicine and to give the majority of the people the benefit of nuclear medicine a better and more active co-operation is needed between all the countries. The paper presents the difficulties and some practical problems of practicing nuclear medicine in a developing country. And also appeals for global co-operation to solve the problems for better interest of the subject

    The nuclear recession is deep, long-lived, and already getting on in years. The great divide in worldwide program developments goes back to the beginning of the seventies. Medium-term nuclear programs are now becoming less and less ambitious, and no sharp upturn can be expected on the time scale of a generation. It seems that, to maintain the nuclear option any farther into the future than that, the minimum prerequisite will be for all the power and industrial activities concerned to integrate the environmental and social costs. Paradoxically, the growing movement in search of a more ''bearable'' development might be the last chance for nuclear power. (author). 39 refs

    Thailand has started the peaceful utilization of nuclear program in 1961. The program has developed considerably in various aspects. Laws and regulations were established while applications in medical, agriculture, industry as well as research and education have been accomplished successfully in the country. As for the energy production, Thailand has realized the importance of nuclear power generation several years back. However, the implementation has been delayed. There are four main nuclear organizations namely The Thai Atomic Energy Commission - the country's policy holder, the Office of Atoms for Peace (OAP) - the nuclear regulatory bodies, Thailand Institute of Nuclear Technology (TINT: Public Organization) - the research and services provider in nuclear field and the Nuclear Society of Thailand the non-governmental organization. Major research in nuclear technology is actively carried out at TINT. Filed of research include medical and public health, agricultural, material and industrial, environmental and advanced technology like neutron scattering and nuclear fusion. Nuclear density gauge has been utilized in many industries including petrochemical production and refineries. TINT is also providing services on nuclear radiography to industrial and clients. Additionally, x-ray techniques have been utilized in many manufacturers for quality and process control. Nuclear applications for medical purpose have been utilized in Thailand several years back both for diagnostic and therapeutic purposes. To ensure safe and peaceful use of nuclear technology and for the safety of the general public in Thailand, OAP has launched laws, regulations and ministerial announcements. Thailand has only one multi-purposes nuclear research reactor and no NPP. Yet we have realized the importance of nuclear power generation several years back. (N.T.)

    Cell size varies greatly among different cell types and organisms, especially during early development when cell division is rapid with little overall growth. A fundamental question is how organelle size is regulated relative to cell size. The nucleus exhibits exquisite size scaling during development and between species, and nuclear size is often altered in cancer cells. Recent studies have elucidated mechanisms of nuclear size regulation in a variety of experimental systems, opening the door to future research on how nuclear size impacts upon cell and nuclear function and subnuclear organization. In this review we discuss studies that have clarified nuclear size control mechanisms and how these results have or will contribute to our understanding of the functional significance of nuclear size.

    Since 1994 the Institute for Transuranium Elements has played the leading role in Europe in the development of Nuclear Forensic Science. This is a new discipline which has developed out of necessity following the break up of the former Soviet Union and Eastern Block countries in 1989, which resulted in the emergence of a new form of illegal smuggling - that of nuclear materials. The Institute has been involved in the investigation of all the major cases of illicit trafficking involving nuclear- and nuclear-related materials in Europe from 1994, following the first major incident at Munich airport, up to the present time. Examples will be given here illustrating different types of cases: the accidental release of nuclear material into the environment, exercises carried out in cooperation with the German Federal Police (Bundeskriminalamt), and the removal of nuclear material with deliberate criminal intent

    An organization, an enterprise or a movement is only as good as the people in it and these cannot be conceived without considering the people that make it, in other words its human resources (HR). The definition of HR includes the total knowledge, skills, creative abilities, talents and aptitudes of the work-force. Equally important it includes the values, attitudes and benefits of each of the individuals concerned. No development is possible without proper planning. HR planning is therefore a prerequisite for HRD in NM and no planning can be made without defining the objectives of Nuclear Medicine (NM) in developing countries (DC). It is also essential to forecast the future needs of NM in DC keeping in mind the stated objectives before laying out the strategies of the HRD. HRD in NM is best achieved when all the partners in the game play their part with commitment and sincerity of purpose. At the national level the partners are the government (ministries of health and education), professional bodies (national societies of NM) and academic bodies (colleges of NM physicians, physicists and technologists etc.). In the implementation of the HRD systems and processes, involvement of all the partners is essential for success. Creation of task forces to implement, monitor and evaluate HRD tools ensures the quality of these tools. The operation of some of these tools may have to be centralized, and others decentralized depending upon the exigencies of need, propriety and practicality. In summary, the aim of HRD should be to ensure the right people at the right time for the right job and in doing so nuclear medicine achieves its objectives and the individuals in the workforce realize their full potentials, and benefits in full

    A unique safety philosophy must be recognized and accepted as an integral part of the design and operation of a nuclear ship. For the nuclear powered ship, the ultimate safety of the reactor and therefore the crew and the environment lies with the safety of the ship itself. The basis for ship safety is its ability to navigate and survive the conditions or the environment in which it may find itself. The subject of traditional ship safety is examined along with its implication for reactor protection and safety. Concepts of reactor safety are also examined. These two philosophies are combined in a manner so as to provide a sound philosophy for the safety of nuclear ships, their crews, and the environment

    Vital problems of environmental impacts of the nuclear power complex are elucidated. Different stages of the nuclear fuel cycle are considered. Presented are some quantitative data on the deaths from lung cancer, comparison of cancer risks due to irradiation and a cool-fueled power plant operation, the effects of different types of power plants on the environment and additional risks for the nuclear fuel cycle plants personnel. The ore mining, milling and enrichment, uranium enrichment, fuel fabrication and normal NPP operation are concluded not to present any serious menace for the environment. Comparisons do show that the detremental effects of coal-fueled power plants are much higher. Probability of an accident resulting in release of large amounts of radionuclides is much lower for a contemporary NPP equipped with proved safety systems, than in other industries. Meanwhile it is not possible nowadays to quantitatively evaluate the effects of reprocessing plants on the environment

    This article attempts to test the causal relationship between nuclear energy consumption and real GDP for nine developed countries for the period 1971-2005 by including capital and labour as additional variables. Using a modified version of the Granger causality test developed by Toda and Yamamoto (1995), we found a unidirectional causality running from nuclear energy consumption to economic growth in Japan, Netherlands and Switzerland; the opposite uni-directional causality running from economic growth to nuclear energy consumption in Canada and Sweden; and a bi-directional causality running between economic growth and nuclear energy consumption in France, Spain, the United Kingdom and the United States. In Spain, the United Kingdom and the USA, increases in nuclear energy consumption caused increases in economic growth implying that conservation measures taken that reduce nuclear energy consumption may negatively affect economic growth. In France, Japan, Netherlands and Switzerland increases in nuclear energy consumption caused decreases in economic growth, suggesting that energy conservation measure taken that reduce nuclear energy consumption may help to mitigate the adverse effects of nuclear energy consumption on economic growth. In Canada and Sweden energy conservation measures affecting nuclear energy consumption may not harm economic growth.

    Full Text Available This paper analyzes the role of nuclear power of China's energy structure and industry system. Comparing with other renewable energy the nuclear power chain has very low greenhouse gas emission, so it will play more important role in China's low-carbon economy. The paper also discussed the necessity of nuclear power development to achieve emission reduction, energy structure adjustment, nuclear power safety, environmental protection, enhancement of nuclear power technology, nuclear waste treatment, and disposal, as well as nuclear power plant decommissioning. Based on the safety record and situation of the existing power plants in China, the current status of the development of world nuclear power technology, and the features of the independently designed advanced power plants in China, this paper aims to demonstrate the safety of nuclear power. A nuclear power plant will not cause harm either to the environment and nor to the public according to the real data of radioactivity release, which are obtained from an operational nuclear plant. The development of nuclear power technology can enhance the safety of nuclear power. Further, this paper discusses issues related to the nuclear fuel cycle, the treatment, and disposal strategies of nuclear waste, and the decommissioning of a nuclear power plant, all of which are issues of public concern.

    By 1990, the Federal Government will have reduced its support for Atomic Energy of Canada Limited's nuclear R and D from the 1985 level of $200 million, to $100 million (1985 dollars). To meet the need for a broadened funding base, AECL Research Company has been restructured to become more responsive to our sponsors and customers. Although supporting the CANDU nuclear power program remains by far our largest R and D activity, we have put in place a comprehensive process for generating new business and commercial activities. Examples of such business opportunities are presented in the paper

  14. Reflections on the development of international nuclear law

    International Nuclear Information System (INIS)

    Lamm, Vanda

    2017-01-01

    Over the course of more than seven decades, treaty norms on the production and utilisation of nuclear energy have been developed, which together form a special section within international law. These norms are the consequence of the unique nature of the field, namely that on the one hand some aspects of the uses of nuclear energy should be covered by totally new and special norms (e.g. in the field of disarmament, seeking to eliminate or at least to control the spread of nuclear weapons, and nuclear weapons tests) and on the other hand that several traditional legal solutions were not suitable for the problems that emerged in connection with other uses of nuclear energy (like liability). In this article, three aspects of the development of that special section of international law will be explored, namely: the close connections between the regulation of peaceful and military uses of nuclear energy; the effects of nuclear catastrophes on the development of international nuclear legislation; and the interaction between soft law norms and binding norms in the area of nuclear law

    This keynote paper deals with: energy issues and nuclear power development in Japan, problems of radiation protection, licensing and safety regulations, research on LOCA and ECCS, stress corrosion cracks related to pressure vessels, nuclear fuel failures, steam generators, incidents, waste management and fuel cycle facilities. In conclusion it is stated that: on order to cope with global matters vitally affecting the electricity generation, taking into consideration Japanese specific energy issues, the nuclear power development has been an indispensable policy of Japan. In order to proceed with further development of nuclear power plants, it is necessary to obtain proper understanding by the public, showing assurance of the safety and reliable operation of nuclear power plants through daily plant operation. The nuclear safety issues should be considered from a global point of view. It is necessary to establish common safety standards which could harmonize the safety level of nuclear power plants in the world. The safety goal concerning severe accidents should be established as an internationally agreeable one. Japan has accumulated highly technological experience in maintenance of nuclear power plants. It is believed that the cumulative experiences in Japan can contribute to the further improvement of safety of nuclear power plants throughout the world, and for this aim a mutual information exchange should be encouraged

  19. RECENT ACTIVITIES AT THE CENTER FOR SPACE NUCLEAR RESEARCH FOR DEVELOPING NUCLEAR THERMAL ROCKETS

    Energy Technology Data Exchange (ETDEWEB)

    Robert C. O' Brien

    2001-09-01

    Nuclear power has been considered for space applications since the 1960s. Between 1955 and 1972 the US built and tested over twenty nuclear reactors/ rocket-engines in the Rover/NERVA programs. However, changes in environmental laws may make the redevelopment of the nuclear rocket more difficult. Recent advances in fuel fabrication and testing options indicate that a nuclear rocket with a fuel form significantly different from NERVA may be needed to ensure public support. The Center for Space Nuclear Research (CSNR) is pursuing development of tungsten based fuels for use in a NTR, for a surface power reactor, and to encapsulate radioisotope power sources. The CSNR Summer Fellows program has investigated the feasibility of several missions enabled by the NTR. The potential mission benefits of a nuclear rocket, historical achievements of the previous programs, and recent investigations into alternatives in design and materials for future systems will be discussed.

  20. Progress on development of nuclear power in Japan

    Anon.

    2000-01-01

    Since three Laws on the nuclear power were published 45 years has passed. Now, development on nuclear power in Japan is at an emergent state. In Japan, 51 units of commercial nuclear reactors with 44.917 GW are in operation, occupy about 37% of total electric power generation, and is positioned at an essential basic energy source supporting economical society in Japan. However, an accident occurred at Tokai Works of the JCO Co., Ltd., one of the uranium reconversion company, on September 30, 1999, was the first critical accident in Japan, and became the worst case in history on development of nuclear power in Japan, because of forming three heavy radiation disabled persons (One of them was dead) in its operators. This was a big crisis with relation to existence on development of nuclear power in Japan, by which anxiety and distrust of the Japanese against the nuclear power were amplified rapidly. On the other side, for Japan short in energy sources and of a big energy consumption, in order to intend for a long term to carry out energy security, global environmental conservation, and sustainable maintenance of essential growth, it remains to be one of important optional methods to further promote nuclear power generation and to establish nuclear fuel cycle. Here were described on progress on peaceful applications of nuclear power in Japan, progress on the field of nuclear power in Japan (from 1955 to 1999), progress on Tokai nuclear power station, introduction of nuclear power generation and effort on its domestic production.

  1. Future scenarios for the development of nuclear power. How will nuclear power develop over the next twenty to forty years?

    International Nuclear Information System (INIS)

    Pickett, Susan E.

    2009-01-01

    Nuclear power technology has developed significantly over the past 60 years to the point that today it supplies the world with 15% of its electricity; and there are plans for continued development. However, the continued growth of nuclear power is not without challenges. The nuclear industry must remain competitive in the face of challenges ranging from environmental considerations and proliferation concerns to ensuring safe and often transparent operations. Understanding these and other issues, as well as their underlying causes, can help the industry leaders create more robust strategies and effectively implement nuclear fuel cycle decisions. Robust strategies are ones that can be effective even when circumstances change, due to events such as opposition, new scientific information, changes in resource availability, or introduction of competing technologies. Scenario planning is tool which can help planners and decision makers create a strategic conversation about the future and how to manage and plan in a time of accelerated change and complexity. In this paper, scenario planning is introduced and the development of nuclear power is examined against the back drop of four future scenarios, specifically looking at how variations in environmental quality, resource availability, security and proliferation, and safety may affect the development of nuclear power. The scenarios discussed provide a starting point to improve the understanding of issues and opportunities facing the global nuclear power industry and ultimately, to improve strategies for technology development. Such scenarios may be employed as a basis for collaboration and communication amongst the stakeholders involved in the development of nuclear technology. (author)

    1985-01-01

    This paper reviews the history and current status of the university nuclear education sector and the utility training sector of the United States (US) nuclear power industry. Recently, the number of programs in the university nuclear education sector has declined, and the remaining programs are in need of both strong governmental and industrial assistance if they are to remain a stable source for educating nuclear engineers and health physicists to staff the resurgence of the nuclear power industry. The utility training sector has undergone remarkable development since the TMI-2 accident. Programs to recruit, train, and qualify the variety of personnel needed, as well as the steps to accredit these programs, are being developed on a systematic, industry-wide basis. A number of new technologies for educating and training personnel are emerging which may be used to create or improve learning environments. Manpower development for the US nuclear power industry is a shared responsibility among the universities, the nuclear utilities, and the nuclear suppliers. This shared responsibility can continue to be best discharged by enhancement of the interaction among all parties with respect to evaluating the proper level of cognitive development within the utility training program

  13. Economic analysis of nuclear power reactor dissemination to less developed nations with implications for nuclear proliferation

    International Nuclear Information System (INIS)

    Gustavson, R.L.; Howard, J.S. II.

    1979-09-01

    We have applied an economic model to the transfer of nuclear-power reactors from industrialized nations to the less developed nations. The model includes demand and supply factors and predicts the success of US nonproliferation positions and policies. We conclude that economic forces dominate the transfer of power reactors to less developed nations. Our study shows that attempts to either restrict or promote the spread of nuclear-power technology by ignoring natural economic incentives would have only limited effect. If US policy is too restrictive, less developed nations will seek other suppliers and thereby lower US Influence substantially. Allowing less developed nations to develop nuclear-power technology as dictated by economic forces will result in a modest rate of transfer that should comply with nuclear-proliferation objectives

    2014-01-01

    Nuclear thermal propulsion has long been considered an enabling technology for human missions to Mars and beyond. One concept of operations for these missions utilizes the nuclear reactor to generate electrical power during coast phases, known as bimodal operation. This presentation focuses on the systems modeling and analysis efforts for a NERVA derived concept. The NERVA bimodal operation derives the thermal energy from the core tie tube elements. Recent analysis has shown potential temperature distributions in the tie tube elements that may limit the thermodynamic efficiency of the closed Brayton cycle used to generate electricity with the current design. The results of this analysis are discussed as well as the potential implications to a bimodal NERVA type reactor.

    2007-01-01

    In this report, the recent topics in the nuclear field, some investigated data on human resources development (HRD) in nuclear field in Japan and the status of HRD and strategy are presented. We have investigated the basic data on HRD in nuclear field in some Asian countries so that the data could be used to develop HRD strategy. The basic data have been investigated for Japan in the following area. (1) Numbers of graduate and undergraduate students and faculty members for each of the nuclear related departments in the universities have been investigated; (2) The information on the academic associations and societies related to nuclear field has been collected; (3) In addition to the basic data directly related to human resources, the data related to the strategy for nuclear utilization such as the data on research reactors, the data on the level of the application of RI and radiation in medicine, agriculture, industry and environment and the future plan to construct NPPs, the number of NPPs being constructed and NPPs under operation have been collected and tabulated for each country. In Japan, many of the experienced nuclear engineers and scientists who have constructed nuclear power plants and developed the application methodology of RI and radiation, are aging and retiring. Also with the decrease in the construction of nuclear power plants and decrease in the nuclear energy research expenditures, it is becoming more difficult to maintain the present level of capability in designing and manufacturing of nuclear facilities. On the other hand, the educational infrastructures in the universities such as nuclear research reactors and the facilities where handling of radioactive materials is permitted, are deteriorating due to the difficulties to meet the more strict regulatory requirements. With the decrease in the popularity of nuclear energy and maturing of nuclear technology it is becoming more difficult to attract sufficient number of promising young individuals

  20. The efficiency calibration and development of environmental correction factors for an in situ high-resolution gamma spectroscopy well logging system

    International Nuclear Information System (INIS)

    Giles, J.R.

    1996-05-01

    A Gamma Spectroscopy Logging System (GSLS) has been developed to study sub-surface radionuclide contamination. Absolute efficiency calibration of the GSLS was performed using simple cylindrical borehole geometry. The calibration source incorporated naturally occurring radioactive material (NORM) that emitted photons ranging from 186-keV to 2,614-keV. More complex borehole geometries were modeled using commercially available shielding software. A linear relationship was found between increasing source thickness and relative photon fluence rates at the detector. Examination of varying porosity and moisture content showed that as porosity increases, relative photon fluence rates increase linearly for all energies. Attenuation effects due to iron, water, PVC, and concrete cylindrical shields were found to agree with previous studies. Regression analyses produced energy-dependent equations for efficiency corrections applicable to spectral gamma-ray well logs collected under non-standard borehole conditions

    2006-01-01

    In Vietnam, nuclear energy has been used in non-power applications for more than 80 years. Health care is a field of the most popular applications of nuclear energy. Every year, hundreds of thousands of people have been diagnosed and treated using nuclear technologies such as radiotherapy, nuclear medicine. In agricultural sector, radiation mutation breeding techniques have been used successfully in creating high quality varieties of rice, soybean, and have made an active contribution in the food security program of the country. The radiation technology has been applied in preservation and pasteurization of some kinds of food, and in production of bio-promoters, hydro gels, etc. The nuclear techniques such as NDT, NCS, and TRACER have been applied in various industries, geology, environment, etc. Recently, the TRACER technique has been used in the management and exploitation of groundwater in Hochiminh City and the Capital of Hanoi. However, effectiveness and scale of non-power applications of nuclear energy is still moderated, does not meet the potential and demand. The studies of nuclear power introduction to Vietnam been carried out for many years and show its necessity and feasibility for the country. Awareness of the advantages of nuclear energy utilization, the Vietnam Government assigned the Ministry of Science and Technology to formulate the long-term strategy for peaceful utilization of nuclear energy in co-operation with other governmental agencies. On 3rd of January 2006, the Prime Minister has approved the long-term strategy for peaceful utilization of nuclear energy. The goal of the strategy is to set up and develop a nuclear technology industry with high contribution to the socio-economic development as well as the enhancement of the science and technology capability of the country. In order to implement the strategy, main solutions have been proposed: Strengthening and perfecting the organizational and management system; Formulation of nuclear legal

    Reliable, long-life power systems are required for ambitious space exploration missions. Nuclear power and propulsion options can enable a bold, new set of missions and introduce propulsion capabilities to achieve access to science destinations that are not possible with more conventional systems. Space nuclear power options can be divided into three main categories: radioisotope power for heating or low power applications; fission power systems for non-terrestrial surface application or for spacecraft power; and fission power systems for electric propulsion or direct thermal propulsion. Each of these areas has been investigated in the United States since the 1950s, achieving various stages of development. While some nuclear systems have achieved flight deployment, others continue to be researched today. This paper will provide a brief overview of historical space nuclear programs in the U.S. and will provide a summary of the ongoing space nuclear systems research, development, and deployment in the United States.

    Countries in this part of the world are engaged in many aspects of nuclear science and technology, often as part of a national development plan. A number of them are members of the Regional Cooperative Agreement (RCA) for Research, Development and Training Related to Nuclear Science and Technology which was developed under the auspices of the International Atomic Energy Agency to provide a basis for nuclear technical assistance and cooperation in the Asia and Pacific region. In contrast to North America and most of western Europe, where growth in installed nuclear generating capacity has ceased, a number of regional countries are planning, ordering and building new power reactors to meet their increasing demands for electricity. Major fuel cycle facilities, such as commercial enrichment and reprocessing plants in Japan, are also being developed. This report describes nuclear developments from power and research reactors to reprocessing facilities in countries of the Asia and Pacific region listed in alphabetical order. Power Reactor and Research Reactors programs in the region as well as lists of regional centres with irradiation facilities are presented in the appendixes The information was gathered from a range of sources, including relevant journals, publications of the International Atomic Energy Agency (IAEA), the OECD/Nuclear Energy Agency(NEA), and annual reports of national nuclear institutes. 1 tab., ill

    Management of nuclear risks - crucial factor for acceptance of novel nuclear projects. We propose an interdisciplinary approach to societal optimization of nuclear energy management. As the keystones we choose: self-organization concept, 2) the principle of the requisite variety. A primary source of growth of internal variety - information and knowledge. Comprehensive knowledge management and informational support firstly is needed in: Technical issues: a) nuclear energy indicators of safety and reliability, b) extensive research and development of advanced technologies, c) multilateral cooperation in common projects; Societal issues: a) general nuclear awareness, b) risk management, engagement in decision-making, personnel education and training, staff renascence, c) public education, stakeholder involvement. There is shown: public education and social learning - efficient self-organization mechanisms, thereby forming a learning and knowledge-creating community. Such an acquired and created knowledge could facilitate solution of key socio-technical issues of nuclear safety as a) public acceptance, in particular, of siting of novel nuclear power plant and radioactive waste disposal objects, b) promotion of adequate perception of risk, equity and trust factors, and c) elevation of safety level of nuclear facilities and adequate management of nuclear risks. The importance of multi-level confidence building at global, regional and national levels is emphasized. (author)

    Remote sensing along with more conventional exploration techniques such as geophysics and reconnaissance field mapping can help to establish regional geologic relationships, to extract major structural features and to pinpoint anomalous patterns. Many well have been drilled in Bengal basin still no commercially viable reserves have been discovered. Geophysical well logging is used in virtually every oil well. It is the primary means by which we characterize the subsurface in search of hydrocarbons. Oil and gas exploration activities for large areas require ground gravity surveys to facilitate detailed geological interpretations for subsurface features integrating geological cross-sections with the sub-surface structural trends leads to the identification of prospect areas. Remote sensing, geological and geophysical data integration provide accurate geometric shapes of the basins. Bengal basin has a sedimentary fill of 10-15 km, is the northernmost of the east coast basins of India In the first phase Remote sensing satellite sensors help in identifying surface anomaly which indicates the presence of hydrocarbon reservoirs providing regional geological settings of petroleferous basins. It provides accurate and visual data for directly determining geometric shapes of basin. It assists in the selection of exploration regions by defining the existence of sedimentary basin. Remote sensing methods can generate a wealth of information useful in determining the value of exploratory prospecting. In the second phase Well Log data provide relative subsurface information for oil and gas exploration. Remote sensing data are merged with other available information such as Aeromagnetic, gravity, geochemical surveys and 2D seismic surveys. The result of this phase is to estimate the outcome of oil discovery probabilities for locating oil prospects

    The paper presents the Brazilian Nuclear Energy Program: its development until the present stage, as well as the organizations and the distribution of responsibilities involved in its execution at the present time. The nuclear power policy is established at the Presidency of the Republic and is planned, executed and controlled through the Ministry of Mines and Energy. Directly subject to the Ministry is the Brazilian Nuclear Energy Commission (CNEN), which has regulatory, standardization, licensing, planning and surveillance functions. The nuclear fundamental research and manpower formation are also under CNEN responsibility. Also subject to the Ministry are two companies responsible for the execution of the Programme: the Centrais Eletricas Brasileiras S.A. - ELETROBRAS, which advises on the granting of permits for the construction and operation of nuclear power plants, and the Empresas Nucleares Brasileiras S.A. - NUCLEBRAS, which holds the monopoly of the nuclear fuel cycle in the country, designs and builds nuclear power plants and provides assistance to the electric utilities as well as promotes the participation of the Brazilian industry in the nuclear field. Besides describing the new distribution of regulatory functions given by law to the CNEN, this paper gives special emphasis to the large industrial complex which is in the process of being established with the setting-up of the many NUCLEBRAS subsidiaries in joint-venture with German firms in the nuclear field, as a consequence of the Industrial Cooperation between Brazil and the Federal Republic of Germany in the Field of the Peaceful Uses of Nuclear Energy signed between the two countries on June 27, 1975. The programs for these subsidiaries are presented and their participation in the Brazilian Nuclear Energy Programme is discussed. The technology transfer aspects of the industrial activities are also discussed, based on the Government's policy on the subject [es

    In the last years we have testified the concern about deterioration of environment, especially, for changes in global scale, either measured or calculated, with unlucky predictions for human kind. Phenomena as acid rain, destruction in the ozone layer and Greenhouse effect, has increased successively the state of alarm in global public opinion, which is already translated either in proliferation of International meetings or in the adoption of recommendations not always pondered and justified. With all these preoccupations, many people is rediscovering that nuclear power dose not produce acid rain, neither CO 2 or Greenhouse effect gases. (Author)

    The U.S. Department of Energy (DOE) national laboratories use their expertise in nuclear science and technology (S&T) to support a robust national nuclear S&T enterprise from the ground up. Traditional academic programs do not provide all the elements necessary to develop this expertise, so the DOE has initiated a number of supplemental programs to develop and support the nuclear S&T workforce pipeline. This document catalogs existing workforce development programs that are supported by a number of DOE offices (such as the Offices of Nuclear Energy, Science, Energy Efficiency, and Environmental Management), and by the National Nuclear Security Administration (NNSA) and the Naval Reactor Program. Workforce development programs in nuclear S&T administered through the Department of Homeland Security, the Nuclear Regulatory Commission, and the Department of Defense are also included. The information about these programs, which is cataloged below, is drawn from the program websites. Some programs, such as the Minority Serving Institutes Partnership Programs (MSIPPs) are available through more than one DOE office, so they appear in more than one section of this document.

    The Integrated Support Center for Nuclear Nonproliferation and Nuclear Security (ISCN) of the Japan Atomic Energy Agency (JAEA) has been providing nuclear security human resource development projects targeting at nuclear emerging countries in Asia in cooperation with the authorities concerned including the Sandia National Laboratory (SNL) and the International Atomic Energy Agency (IAEA). In the aftermath of the attacks of Sept. 11, the threat of terrorism was internationally recognized and thus the human resource capacity building is underway as an urgent task. In order to responding to emerging threats, the human resource capacity building that ISCN has implemented thus far needs to be multilaterally analyzed in order to develop more effective training programs. This paper studies ISCN's future direction by analyzing its achievements, as well as introduces the collaborative relationships with SNL that contributes to the reflection and maintenance of international trends for the contents of nuclear security training, the nuclear security enhancement support with which Japan is to provide nuclear emerging countries in Asia, and the achievements of the nuclear security training program that ISCN implemented.

    NEDO is now carrying out `the deep-seated geothermal resource survey` with the aim of surveying deep geothermal resource lying 3,000m below sea level. `The development of resistivity use investigation technology` being carried out as element technology for this survey conducts well surveys and earth surface-well surveys using the drilled deep wells. By analyzing these surveys together with electromagnetic method surveys including the MT method carried out on the earth surface, the survey was aimed at grasping in high resolution resistivity structures from the shallow underground to the deep underground. The multi-frequency array induction logging being researched as the well survey is a method to grasp resistivity structures within a radius of several meters of the well using the electromagnetic logging method. The paper reported the field test conducted this time using the improved tool. A comparison of the data obtained in the test with the results of the normal logging showed consistency, and therefore, it showed that the tool itself fully grasped responses from strata. 3 refs., 5 figs., 1 tab.

    South Africa's long nuclear history has enabled it to develop and explore new nuclear technologies. The country's nuclear industry is becoming innovative and will soon be able to compete within the global nuclear market. This includes projects such as the Pebble-Bed Modular Reactor (PBMR), a generation IV reactor technology, whose construction is anticipated by 2009. This will put South Africa in the fore-front of new technologies. Globally, the nuclear sector is experiencing a renaissance with political support from most governments. The South African government intends to expand the nuclear component in the energy supply mix of the country as a result of an energy crisis resulting from economic growth and thus high demand which will soon outstrip supply. This increased energy demand requires the country to take measures to counteract the crisis. It has been projected that an additional 40000 Megawatts of electricity will be required over the next 20 years in South Africa. Currently about 90% of South Africa's electricity is generated from coal and about 6% from nuclear. The South African electricity utility, Eskom is investigating the expansion of the utility's nuclear power capacity. These investigations are aimed at a potential increase of nuclear capacity to 20000 Megawatts by 2025. Eskom is in the initial phase of the investigation and is considering advanced Pressurized Water Reactors (PWRs) with a combined capacity of around 3500 Megawatts. This planned expansion of the nuclear energy generating program has presented a challenge of developing and maintaining skills and competencies required by the program. The South African government has acknowledged that they do have a challenge and are going to have to develop an aggressive approach to acquire the necessary skills and competencies required for the program. This aggressive approach will have to accelerate the development of nuclear human capital capacity by ensuring that we utilize the

  4. Nuclear Positioning in Muscle Development and Disease

    Full Text Available Muscle disease as a group is characterized by muscle weakness, muscle loss, and impaired muscle function. Although the phenotype is the same, the underlying cellular pathologies, and the molecular causes of these pathologies, are diverse. One common feature of many muscle disorders is the mispositioning of myonuclei. In unaffected individuals myonuclei are spaced throughout the periphery of the muscle fiber such that the distance between nuclei is maximized. However, in diseased muscles, the nuclei are often clustered within the center of the muscle cell. Although this phenotype has been acknowledged for several decades, it is often ignored as a contributor to muscle weakness. Rather, these nuclei are taken only as a sign of muscle repair. Here we review the evidence that mispositioned myonuclei are not merely a symptom of muscle disease but also a cause. Additionally, we review the working models for how myonuclei move from two different perspectives, from that of the nucleus and from that of the cytoskeleton. We further compare and contrast these mechanisms with the mechanisms of nuclear movement in other cell types both to draw general themes for nuclear movement and to identify muscle-specific considerations. Finally, we focus on factors that can be linked to muscle disease and find that genes that regulate myonuclear movement and positioning have been linked to muscular dystrophy. Although the cause-effect relationship is largely speculative, recent data indicate that the position of nuclei should no longer be considered only a means to diagnose muscle disease.

    The concept of sustainable development was elaborated in the late 1980s and was defined as a development that fulfills the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable development incorporates equity within and across countries as well as across generations, and integrates economic growth, environmental protection and social welfare. To analyze nuclear energy from a sustainable development perspective it is necessary to consider its economic, environmental and social impacts characteristics, both positive and negative. It is obvious that the development of nuclear energy broadens the natural resource base usable for energy production, and increases human and man-made capital. There are also many arguments in favor of nuclear energy as a reliable source such as: the large size of the nuclear power plants, their long periods of operation and the existent experience for operation. The risks associated with radiation are among the most extensively studied hazards known by man, but several factors are preserving public anxiety about radiation. Radiation is inaccessible to human senses, difficult to understand, and probabilistic in its effects, which to the public means uncertainty. Hence, radiological protection is essential to ensure that nuclear energy is compatible with sustainable development. Nuclear energy has, in normal operation, a low impact on health and environment. In order to meet the sustainable development goals, it is necessary to maintain its high standards of safety in spite of increasing competition in the electricity sector and reactors ageing in order to achieve a higher level of public acceptance. The complex technologies used by nuclear fuel cycle facilities are controlled and regulated by international and national institutions. A framework of regulatory, institutional and technical measures is already in place ensuring that the use of nuclear energy does not significantly modify

    To improve the monitoring of logging company performance, computer programs were developed to assess information en masse from log quality check lists completed on wellsite by the service company engineer and Phillips representative. A study of all logging jobs performed by different service companies for Phillips in Oklahoma (panhandle excepted) during 1982 enabled several pertinent and beneficial interpretations to be made. Company A provided the best tool and crew service. Company B incurred an excessive amount of lost time related to tool failure, in particular the neutron-density tool combination. Company C, although used only three times, incurred no lost time. With a reasonable data base valid conclusions were made pertaining, for example, to repeated tool malfunctions. The actual logs were then assessed for quality

    The Korean government announced the 'Basic Plan for National Energy towards 2030' last year. The goal of the plan is to achieve energy security, energy efficiency and environmental protection. To achieve green development Korean government plans to increase the portion of nuclear and renewable energy and reduce that of coal and oil energy. According to the plan, Korea will build another 9 units until 2030 and nuclear energy will represent 59% of electricity demands by 2030 which is about 20% higher than last year. Even though environment surrounding the nuclear industry is changing favorably and the government has a plan to increase nuclear energy for green development and optimal energy mix, we have to meet some challenges in the area of safety, waste disposal, public acceptance, and technology development. In this paper, we introduced the history, current status and future prospect of the nuclear industry in Korea, discussed new roles of nuclear energy, and made suggestions how to meet challenges and brace up for the global nuclear renaissance.

    The nuclear fuel cycle is a most important industry for the energy future of the world. It has also a leading part as regards the physical continuity of energy supply of the countries engaged in the nuclear field. The development of this industry is subject to the economic or political constraints involved by the availability of raw materials, technologies or production means. The various limiting factors which could affect the different stages of the fuel cycle are linked with the technical, economic and financial aspects, with the impact on the environment, nuclear safety, risks of non-pacific uses and proliferation of arms. Interesting to note is also the correlation between the fuel cycle development and the problems of energy independence and security of nuclear programs. As a conclusion, the nuclear fuel cycle industry is confronted to difficulties due to its extremely rapid growth (doubling time 5 years) which only few heavy industries have encountered for long periods. It is more over submitted to the political and safety constraints always linked with nuclear matters. The task is therefore a difficult one. But the objective is worth-while since it is a condition to the development of nuclear industry [fr

    The long-term energy supply simulation that optimizes the energy system cost until 2100 for the world is being performed, by using the energy module of GRAPE model, where energy demand under the C02 emission constraint etc. is assumed. The model has been taken up for the trial calculation in I PCC the third report . Role and potential of nuclear energy system in the energy options is discussed here from the viewpoint of sustainable development with protecting from global warming. Taking the effort for energy conservation as major premise, carbon-sequestration for fossil fuel, renewable energy and nuclear energy should be altogether developed under the C02 constraint. Especially, fast breeder reactor will be attached importance to, as the 22nd century is approaching, due to its carbon free and resource limitless features when the nuclear generation cost is cheap as a current light water reactor level. It takes time around 30 years in order for breeding of Pu, a fast breeder reactor will begin to be introduced from around 2030. If the period for the technology establish of nuclear fuel cycle is assumed to be 30 years, it is necessary to start technical development right now. If the Kyoto Protocol, the emission constraint on only the developed countries, is extended in 21st century, it will promote the growth of nuclear power in the developed countries in the first half of the century. After 2050, the developing countries will face the shortage of uranium and plutonium. Carbon emission constraint should be covered all countries in the World not only for the developed countries but also for the developing countries. Therefore, it is important that the developing countries will use nuclear power effectively from the viewpoint of harmonization of energy growth and global environment. The policy that nuclear power is considered as Clean Development Mechanism would mitigate such global warming problems

    The purpose of this paper is to develop a model, a general frame to be utilized in assisting newcomer countries to start a nuclear power program. A nuclear power plant project involves technical complexity and high level of investment with long duration. Considering newcomers are mostly developing countries that lack the national infrastructure, key infrastructure issues may constitute the principal constraints to the development of a nuclear power program. In this regard, it is important to provide guidance and support to set up an appropriate infrastructure when we help them with the first launch of nuclear power plant project. To date, as a sole nuclear power generation company, KHNP has been invited many times to mentor or assist newcomer countries for their successful start of a nuclear power program since Republic of Korea is an exemplary case of a developing country which began nuclear power program from scratch and became a major world nuclear energy country in a short period of time. Through hosting events organized to aid newcomer countries' initiation of nuclear power projects, difficulties have been recognized. Each event had different contents according to circumstances because they were held as an unstructured and one-off thing. By developing a general model, we can give more adequate and effective aid in an efficient way. In this paper, we created a model to identify necessary infrastructures at the right stage, which was mainly based on a case of Korea. Taking into account the assistance we received from foreign companies and our own efforts for technological self-reliance, we have developed a general time table and specified activities required to do at each stage. From a donor's perspective, we explored various ways to help nuclear infrastructure development including technical support programs, training courses, and participating in IAEA technical cooperation programs on a regular basis. If we further develop the model, the next task would be to

    The Japan Nuclear Ship Development Agency held the annual report meeting on April 8, 1981. The main contents were the plan of research and development of nuclear ships hereafter, the present state of the repair works for the nuclear ship ''Mutsu'', the progress of the selection of the new home port and others. In the last year, the function of research was given to the Agency by the revision of the related law. The full-scale repair works for Mutsu were started in August, 1980, and various equipments and shields in the containment vessel and the upper shields of the containment vessel have been removed. Subsequently, new shields are being installed. According to the report by the committee of nuclear ship research and development, the development of Mutsu, which is valuable as the experimental ship, is continued. Moreover, it is proposed to do the research and development of an improved marine nuclear plant for the purposes of securing the economic efficiency, the proving of the reliability of nuclear merchant ships, and the establishment of safety. As the home port for Mutsu, the new port will be constructed on the open sea side in Aomori Prefecture, and as a candidate, Sekine beach in Mutsu City was named. Till the completion of the new home port, Mutsu will be berthed in Ominato home port. The conditions for entering and berthing in Ominato port will be decided later. (Kako, I.)

    Economical, environmental and non-proliferation issues associated with sustainable development of nuclear power bring about a need for optimization of fuel cycles and implementation of advanced nuclear systems. While a number of physical and design concepts are available for innovative reactors, the absence of reliable materials able to sustain new challenging irradiation conditions represents the real bottle-neck for practical implementation of these promising ideas. Materials performance and integrity are key issues for the safety and competitiveness of future nuclear installations being developed for sustainable nuclear energy production incorporating fuel recycling and waste transmutation systems. These systems will feature high thermal operational efficiency, improved utilization of resources (both fissile and fertile materials) and reduced production of nuclear waste. They will require development, qualification and deployment of new and advanced fuel and structural materials with improved mechanical and chemical properties combined with high radiation and corrosion resistance. The extensive, diverse, and expensive efforts toward the development of these materials can be more effectively organized within international collaborative programmes with wide participation of research, design and engineering communities. IAEA carries out a number of international projects supporting interested Member States with the use of available IAEA program implementation tools (Coordinated Research Projects, Technical Meetings, Expert Reviews, etc). The presentation summarizes the activities targeting material developments for advanced nuclear systems, with particular emphasis on fast reactors, which are the focal topics of IAEA Coordinated Research Projects 'Accelerator Simulation and Theoretical Modelling of Radiation Effects' (on-going), 'Benchmarking of Structural Materials Pre-Selected for Advanced Nuclear Reactors', 'Examination of advanced fast reactor fuel and core

    The Fukushima Daiichi nuclear power plant accident has had an impact on the development of nuclear power around the world. While the accident was followed by thorough technical assessments of the safety of all operating nuclear power plants, and a general increase in safety requirements has been observed worldwide, national policy responses have been more varied. These responses have ranged from countries phasing out or accelerating decisions to phase out nuclear energy to countries reducing their reliance on nuclear power or on the contrary continuing to pursue or expand their nuclear power programs. This study examines changes to policies, and plans and attempts to distinguish the impact of the Fukushima Daiichi accident from other factors that have affected policy-making in relation to nuclear energy, in particular electricity market economics, financing challenges and competition from other sources (gas, coal and renewables). It also examines changes over time to long-term, quantitative country projections, which reveal interesting trends on the possible role of nuclear energy in future energy systems. (authors)

    Nuclear industry in Japan established a fixed foundation as a large complex system industry by elapsing about forty years since beginning of its development at top of 1930s. For Japan with little energy resources, nuclear power generation is one of essential choices because not only of keeping energy security but also of response to global warming problem such as global warming protection. Then, in order to intend to promote sound development of the nuclear industry in Japan, further upgrading of technology aimed at maintenance and improvement of safety and formation of understanding and agreement of the peoples must be established. Here was introduced a report on actual state of the nuclear industry in Japan in 1997 fiscal year prepared on February, 1999 by the Japan Atomic Industrial Forum. (G.K.)

    The project aimed at studying the concept of nuclear safety culture and the Nordic nuclear branch safety culture. The project also aimed at looking how the power companies and the regulators view the current responsibilities and role of subcontractors in the Nordic nuclear safety culture as well as to inspect the special demands for safety culture in subcontracting chains. Interview data was collected in Sweden (n = 14) and Finland (n = 16) during 2009. Interviewees represented the major actors in the nuclear field (regulators, power companies, expert organizations, waste management organizations). Results gave insight into the nature and evaluation of safety culture in the nuclear industry. Results illustrated that there is a wide variety of views on matters that are considered important for nuclear safety within the Nordic nuclear community. However, the interviewees considered quite uniformly such psychological states as motivation, mindfulness, sense of control, understanding of hazards and sense of responsibility as important for nuclear safety. Results also gave insight into the characteristics of Nordic nuclear culture. Various differences in safety cultures in Finland and Sweden were uncovered. In addition to the differences, historical reasons for the development of the nuclear safety cultures in Finland and Sweden were pointed out. Finally, results gave implications that on the one hand subcontractors can bring new ideas and improvements to the plants' practices, but on the other hand the assurance of necessary safety attitudes and competence of the subcontracting companies and their employees is considered as a challenge. The report concludes that a good safety culture requires a deep and wide understanding of nuclear safety including the various accident mechanisms of the power plants as well as a willingness to continuously develop one's competence and understanding. An effective and resilient nuclear safety culture has to foster a constant sense of

    Nuclear industry is strongly regulated all over the world and quality assurance is important in every nuclear installation or process related with it. Nuclear fuel manufacture is not the exception. ININ was committed to manufacture four nuclear fuel bundles for the CFE nucleo electric station at Laguna Verde, Veracruz, under General Electric specifications and fulfilling all the requirements of this industry. One of the quality control requisites in nuclear fuel manufacture deals with the enrichment of the pellets inside the fuel bundle rods. To achieve the quality demanded in this aspect, the system described in this work was developed. With this system, developed at ININ it is possible to detect enrichment spikes since 0.4 % in a column of pellets with a 95 % confidence interval and to identify enrichment differences greater than 0.2 % e between homogeneous segments, also with a 95 % confidence interval. ININ delivered the four nuclear fuel bundles to CFE and these were introduced in the core of the nuclear reactor of Unit 1 in the fifth cycle. Nowadays they are producing energy and have shown a correct mechanical performance and neutronic behavior. (Author)

  8. Pulsed neutron generator for logging

    International Nuclear Information System (INIS)

    Thibideau, F.D.

    1977-01-01

    A pulsed neutron generator for uranium logging is described. This generator is one component of a prototype uranium logging probe which is being developed by SLA to detect, and assay, uranium by borehole logging. The logging method is based on the measurement of epithermal neutrons resulting from the prompt fissioning of uranium from a pulsed source of 17.6 MeV neutrons. An objective of the prototype probe was that its diameter not exceed 2.75 inches, which would allow its use in conventional rotary drill holes of 4.75-inch diameter. This restriction limited the generator to a maximum 2.375-inch diameter. The performance requirements for the neutron generator specified that it operate with a nominal output of 5 x 10 6 neutrons/pulse at up to 100 pulses/second for a one-hour period. The development of a neutron generator meeting the preliminary design goals was completed and two prototype models were delivered to SLA. These two generators have been used by SLA to log a number of boreholes in field evaluation of the probe. The results of the field evaluations have led to the recommendation of several changes to improve the probe's operation. Some of these changes will require additional development effort on the neutron generator. It is expected that this work will be performed during 1977. The design and operation of the first prototype neutron generators is described

    The essential ingredients of sustainable development are economics and efficiency in the use of energy and materials, and in the prevention, disposal and recycling of wastes. Nuclear power will continue to be an important means of electricity generation for the foreseeable future but the extent to which this will be the case depends on the nuclear industry resolving public concerns over environmental, health and safety risks, and competing successfully with other generating technologies. In the final analysis, the future of nuclear power will be determined primarily by economic considerations. (UK)

    2002-01-01

    Full text: For the developing countries, managing nuclear knowledge requires both acquiring know-how from the developed countries as well as building and conserving their own knowledge resource. The rapid growth of information technology culture has made vast amounts of information and database universally accessible although some bars do indeed apply. The challenge, therefore, lies in having a continuous supply of different tiers of trained and competent professionals who can benefit from what is available and can carry on developing the indigenous capability. This presentation focuses on the issues and problems faced in meeting the above challenge. Steps taken in a developing country like Pakistan to manage nuclear knowledge will be discussed. These measures include developing an interface between the universities and the industry as well as concentrating on meeting the specific infrastructure requirements. The task is, however, becoming increasingly difficult for the developing countries because of the fall out of the lack of proper growth in the nuclear industry at the global level, and the large and long-term financial commitments associated with nuclear energy which leave the entire burden of the nuclear power program development on the public sector.

    Within a year after the nuclear detonations over Hiroshima and Nagasaki the Baruch Plan was presented to the newly formed United Nations Atomic Energy Commission (June 14, 1946) to establish nuclear disarmament and international control over all nuclear activities. These controls would allow only the peaceful use of atomic energy. The plan was rejected through a Security Council veto primarily because of the resistance to unlimited inspections. Since that time there have been many multilateral, and bilateral agreements, and unilateral declarations to limit or eliminate nuclear detonations. Almost all of theses agreements (i.e. treaties) call for some type of monitoring. We will review a timeline showing the history of nuclear testing and the more important treaties. We will also describe testing operations, containment, phenomenology, and observations. The Comprehensive Nuclear Test Ban Treaty (CTBT) which has been signed by 179 countries (ratified by 144) established the International Monitoring System global verification regime which employs seismic, infrasound, hydroacoustic and radionuclide monitoring techniques. The CTBT also includes on-site inspection to clarify whether a nuclear explosion has been carried out in violation of the Treaty. The US Department of Energy (DOE) through its National Nuclear Security Agency's Ground-Based Nuclear Explosion Monitoring R&D Program supports research by US National Laboratories, and universities and industry internationally to detect, locate, and identify nuclear detonations. This research program builds on the broad base of monitoring expertise developed over several decades. Annually the DOE and the US Department of Defense jointly solicit monitoring research proposals. Areas of research include: seismic regional characterization and wave propagation, seismic event detection and location, seismic identification and source characterization, hydroacoustic monitoring, radionuclide monitoring, infrasound monitoring, and

    Finding a way to generate electricity so as to satisfy the terms of sustainable development of the entire society is the only way which will secure safe energy future. If we talk about energy in the context of sustainable development, one of the most important element is environmental protection. Since CO 2 emissions stemming from electricity generation have predominant impact on climate change, one of the options for reducing emissions is the use of fuels without carbon, such as e.g. nuclear fuel. The future of nuclear power plants was considered in view of: nuclear fuel supply; potential impact of fuel cycle on environment, power plant operation, decommissioning and secondary products from electricity generation; and the entire nuclear power plant economy. Nuclear power plants were also examined in the context of the Kyoto Protocol stipulating reduction of greenhouse gases emissions. Nuclear power plants can not reduce CO 2 emissions in a short-term because they already operate with maximum output, but in a long-run they can play a significant role. This paper is aiming to analyse the role of nuclear power plants in long term environmental sustainability in electricity sector reform (liberalisation, deregulation, privatisation) in small or medium sized power supply systems. Nuclear power plants are associated with certain environmental aspects which will be taken into account. A comparison will be made through externalities with other energy resources, especially fossil fuels, which are prevailing energy resources, considering possible use of nuclear power plants in the countries with small and medium-size grids. It will be given an example of the role of NPP Krsko on air emissions reduction in Croatia. (author)

    The disposal facility of the spent nuclear fuel will be operated from 2051. This paper presents the ENVI code developed by GoldSim Software to simulate options for managing spent nuclear fuel (SNF) in South Korea. The ENVI is a simulator to allow decision-makers to assist to evaluate the performance for spent nuclear fuel management. The multiple options for managing the spent nuclear fuel including the storage and transportation are investigated into interim storage, permanent disposal in geological repositories and overseas and domestic reprocessing. The ENVI code uses the GoldSim software to simulate the logistics of the associated activities. The result by the ENVI model not only produces the total cost to compare among the multiple options but also predict the sizes and timings of different facilities required. In order to decide the policy for spent nuclear management this purpose of this paper is to draw the optimum management plan to solve the nuclear spent fuel issue in the economical aspects. This paper is focused on the development of the ENVI's logic and calculations to simulate four options(No Reprocessing, Overseas Reprocessing, Domestic Reprocessing, and Overseas and Domestic Reprocessing) for managing the spent nuclear fuel in South Korea. The time history of the spent nuclear fuel produced from both the existing and future NPP's can be predicted, based on the Goldsim software made available very user friendly model. The simulation result will be used to suggest the strategic plans for the spent nuclear fuel management

    Nova is a 200 terawatt, 10-beam High Energy Glass Laser currently under construction at LLNL. This facility, designed to demonstrate the feasibility of laser driven inertial confinement fusion, contains over 5000 elements requiring coordinated control, data acquisition, and analysis functions. The large amounts of data that will be generated must be maintained over the life of the facility. Often the most useful but inaccessible data is that related to time dependent events associated with, for example, operator actions or experiment activity. We have developed an Event Logging System to synchronously record, maintain, and analyze, in part, this data. We see the system as being particularly useful to the physics and engineering staffs of medium and large facilities in that it is entirely separate from experimental apparatus and control devices. The design criteria, implementation, use, and benefits of such a system will be discussed

    Full Text Available A business process or workflow is an assembly of tasks that accomplishes a business goal. Business process management is the study of the design, configuration/implementation, enactment and monitoring, analysis, and re-design of workflows. The traditional methodology for the re-design and improvement of workflows relies on the well-known sequence of extract, transform, and load (ETL, data/process warehousing, and online analytical processing (OLAP tools. In this paper, we study the ad hoc queryiny of process enactments for (data-centric business processes, bypassing the traditional methodology for more flexibility in querying. We develop an algebraic query language based on “incident patterns” with four operators inspired from Business Process Model and Notation (BPMN representation, allowing the user to formulate ad hoc queries directly over workflow logs. A formal semantics of this query language, a preliminary query evaluation algorithm, and a group of elementary properties of the operators are provided.

    Over 60 technical experts of the reactor safety research division of the Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) gGmbH are developing and validating reliable methods and computer codes - summarized under the term nuclear simulation chain - for the safety-related assessment for all types of nuclear power plants (NPP) and other nuclear facilities considering the current state of science and technology. This nuclear simulation chain has to be able to simulate and assess all relevant physical processes and phenomena for all operating states and (severe) accidents. In the present contribution, the nuclear simulation chain developed and applied by GRS as well as selected examples of its application are presented. The latter demonstrate impressively the width of its scope and its performance. The GRS codes can be passed on request to other (national as well as international) organizations. This contributes to a worldwide increase of the nuclear safety standards. The code transfer is especially important for developing and emerging countries lacking the financial means and/or the necessary know-how for this purpose. At the end of this contribution, the respective course of action is described.

    1999-01-01

    We prove that every log crepant birational morphism between log terminal surfaces is decomposed into log-flopping type divisorial contraction morphisms and log blow-downs. Repeating these two kinds of contractions we reach a minimal log minimal surface from any log minimal surface.

  6. New risks for a new era in nuclear power development

    International Nuclear Information System (INIS)

    Purica, I.

    2002-01-01

    At present, the nuclear power is re-emerging after a still ongoing controversial period. The risks, that have started to be analyzed in the nuclear industry, opened the way for methods and algorithms that are wide spread now in all situations whose strong dynamics requires that kind of approach. The onset of terrorism in the last year and risk exposure of the nuclear power plants, that are potential sources of hazards if targeted appropriately, require orienting the risk methods to this type of analysis along with the technical solutions. Also, the financial volatility of the world of today, creates barriers in the development of nuclear plant financial structures. The possibility to combine the decommissioning of old thermal capacities and their replacement with nuclear capacities that results in Emission Reduction Units that can be traded internationally, raise the opportunity for a better financial structure of nuclear power projects in connection with thermal capacity shutdown. The risk decreasing is significant and the impact on the costs make nuclear power even more cost-effective. In the paper we review some aspects of terrorism risk analysis and the impact of emission trading on the financial structure of an NPP project in very conservative conditions. (author)

    2008-01-01

    The development status and existing problems in the field of nuclear agricultural sciences (NAS) are reviewed. Including the application of nuclear technology in mutation breeding by irradiation, isotopic technique application, food irradiation and sterile insect technique, etc. China has made great achievements in the research and application of nuclear technique in agriculture from 1950s to 1990s. Due to lack of enough financial support to the basic research and reformation of science and research system in China, the development of NAS now meets its tough time. Through analyzing the difference and reasons of NAS development between China and the USA, it is recognized that the innovation in research and scientific system is important for promoting the development speed and research level of NAS.

    States who wish to start and develop a nuclear program must take into consideration a strong proven strategy for developing a sustainable program. A complete nuclear research program must include: a good national strategy and support on the topic; strong research laboratories supported by good personnel; education component to provide sustainable and qualified workforce; national/international interest from stakeholders and governments and a well informed society. New demonstrators are foreseen for the next period to be built in Europe and skilled supporting personnel is strongly needed. Current situation in nuclear higher education with perspective will be analysed. EURATOM strongly supports development of multidisciplinary co-operational projects in order to built such novel initiatives. An example of such program supported by European Commission, ARCADIA, will be given. The project is based on the cooperation of a large number of participants all over Europe and the main purpose is to develop a road-map for Gen IV reactor. (authors)

  9. Dynamic functional studies in nuclear medicine in developing countries

    International Nuclear Information System (INIS)

    1989-01-01

    The Proceedings document some of the trials and tribulations involved in setting up nuclear medicine facilities in general and specifically as regards nuclear medicine applications for the diagnosis of the diseases prevalent in the less developed countries. Most of the 51 papers deal with various clinical applications of dynamic functional studies. However, there was also a session on quality control of the equipment used, and a panel discussion critically looked at the problems and potential of dynamic studies in developing countries. This book will be of interest and use not only to those practising nuclear medicine in the developing countries, but it may also bring home to users in developed countries how ''more can be done with less''.

  10. Thailand: Infrastructure Development and Challenges to Launch Nuclear Power Programme

    International Nuclear Information System (INIS)

    Keinmeesuke, Sirichai

    2011-01-01

    In June 2007, the cabinet passed a resolution for Thailand's Power Development Plan (PDP 2007). It was mentioned in the plan that Thailand will have 2 x 1,000 MWe nuclear power plants in 2020 and another 2 x 1,000 MWe in 2021. The PDP 2007 was revised in March 2009 and it was agreed to change the nuclear power generation to only 1 x 1,000 MWe in 2020 and 2021 respectively due to the large excess capacity at present. Many activities related to development of infrastructures in order to support electricity generation using nuclear power are being executed. Milestones for nuclear power program implementation has been developed using the IAEA document 'Milestones in the Development of a National Infrastructure for Nuclear Power' with some amendment/additions to suit the country situation. According to the schedule, a lot of activities related to infrastructure establishment, feasibility study, utility preparation and public education and participation are being performed. Within the year 2011, various issues such as legal and regulatory systems and international commitment, industrial and commercial infrastructure, technology transfer and human resource development, safety and environmental protection, public information and public acceptance, preparation of the nuclear power utility establishment, etc. must be solved out and undertaken to assure the cabinet to make final decision to go nuclear. There are many challenges for Thailand embarking of the nuclear power programme. It is essential to plan for the establishment of a regulatory body at the national level to support and regulate the nuclear power plant industry. Currently, the application for a license and the monitoring of a power plant are administered by the authorities of various agencies under different ministries; hence the process is very time-consuming and overlaps with one another. The approach that the regulatory body and the authorities to issue licenses relevant to the nuclear power plant operation

    1998-01-01

    In parallel to its vigorous program of nuclear power generation, China has attached great importance to the development of nuclear reactors for non-electrical applications. The Institute of Nuclear Energy Technology (INET) in Beijing has been developing technologies of the water-cooled heating reactor and the modular high temperature gas-cooled reactor. In 1989, a 5 MW water cooled test reactor was erected. Currently, an industrial demonstration nuclear heating plant is being projected. Feasibility studies are being made of sea-water desalination using the INET developed nuclear heating reactor as heat source. Also, a 10 MW high temperature gas-cooled test reactor is being constructed at INET in the framework of China's national high-tech program. The paper gives an overview of China's energy market situation. With respect to China's technology development of high temperature gas-cooled reactors and water cooled heating reactors, the paper describes some general requirements on the technical development, reviews the national programs and activities, describes briefly the design and safety features of the reactor concepts, discusses aspects of application potentials.

  16. Developing a Nuclear Global Health Workforce Amid the Increasing Threat of a Nuclear Crisis.

    Burkle, Frederick M; Dallas, Cham E

    2016-02-01

    This study argues that any nuclear weapon exchange or major nuclear plant meltdown, in the categories of human systems failure and conflict-based crises, will immediately provoke an unprecedented public health emergency of international concern. Notwithstanding nuclear triage and management plans and technical monitoring standards within the International Atomic Energy Agency and the World Health Organization (WHO), the capacity to rapidly deploy a robust professional workforce with the internal coordination and collaboration capabilities required for large-scale nuclear crises is profoundly lacking. A similar dilemma, evident in the early stages of the Ebola epidemic, was eventually managed by using worldwide infectious disease experts from the Global Outbreak Alert and Response Network and multiple multidisciplinary WHO-supported foreign medical teams. This success has led the WHO to propose the development of a Global Health Workforce. A strategic format is proposed for nuclear preparedness and response that builds and expands on the current model for infectious disease outbreak currently under consideration. This study proposes the inclusion of a nuclear global health workforce under the technical expertise of the International Atomic Energy Agency and WHO's Radiation Emergency Medical Preparedness and Assistance Network leadership and supported by the International Health Regulations Treaty. Rationales are set forth for the development, structure, and function of a nuclear workforce based on health outcomes research that define the unique health, health systems, and public health challenges of a nuclear crisis. Recent research supports that life-saving opportunities are possible, but only if a rapidly deployed and robust multidisciplinary response component exists.

  17. Developing engineering capabilities as a support to a nuclear program

    International Nuclear Information System (INIS)

    Rodriguez, A.G.

    1986-04-01

    The performance of a nuclear program needs a quite substantial and diversified volume of technological resources. Its integrated management is one of the basic aspects to be settled. In this regard, the creation of strong engineering organizations with the ability to develop management of the project technical activities as a whole has had success in various countries. These organizations should be provided with suitable means to rapidly assimilate the technology and should serve as a channel and support to local industry in general. The development of a nuclear program also requires the collaboration of other institutions, such as universities and research and development centers. In this sense, engineer and technician training necessities are important both in number and technological qualification, as is the availability of capacities in such different areas as simulation and advanced calculation, geology and soil mechanics, materials, fabrication processes, test laboratories, etc. The volume of technological activities to be developed in relation to a stable, although not necessarily large, nuclear program justifies in itself the assigning of important resources to all the above mentioned activities. However, it should be noted that it has been proved that the nuclear industry is completely pervious as regards other fields of activity. In fact, the more stringent quality requirements are quickly transmitted to other industrial processes, and the engineers trained in this area undergo a far from contemptible turnover towards non-nuclear activities. The basic research area in the nuclear field is not in itself a requirement that has to be in parallel with the development of a nuclear program. However, on medium and long-term bases, it may be interesting for a well balanced commercial program that research activities be established realistically and sensibly, even though short-term practical applications are not necessarily derived from this

    The main goal of this project is to develop the fundamental techniques of physical and chemical analysis of the target materials, and data interpretation methods to identify the origin and the production attributions of intercepted illicit nuclear or radioactive materials. This also includes production of analytical data for domestic nuclear materials to be used in establishment of national nuclear material data library. As the result of the R and D of this project, we developed the analytical techniques for H and O isotopes to identify the origin of the target samples, the techniques of chemical treatments of water type and soil type samples, and the fundamental research on the gamma spectroscopy for nuclear forensics. We also performed the study on the national collaboration plan on nuclear forensics, and fundamental research and the target materials and analytical requirements for analytical data production of domestic nuclear materials to construct a national data library. Most of the R and D's in the schedule of this project have not been performed due to the early termination of the project by the decision of the government

    Russia and China have clear policy for the export of nuclear reactors, and both countries conduct negotiations with the initiative of the government. In Russia, Atomenergoprom, which controls civilian nuclear power sector, is in charge, and in China, CNNC, CGN, and SPI are in charge. As for the development of new type reactors, Russian type VVER-1200 is led by NIAEP and Atomproekt, and China type CAP 1400 and Hualong-1 are led by CNNC, CGN, and SPI. The next reactor export is considered to be an improved type of the third generation. Furthermore, both countries are proceeding with the construction and planning of a variety of the fourth generation reactors. As for the power generation and construction costs of domestic nuclear reactors in each country, three countries such as South Korea, China, and Russia hold a dominant position, keeping the costs significantly lower than those in Japan, the United States, and France. In Russia and China, the governments approve government support loans of approximately 5 to 9 billion dollars per reactor for exporting reactors. For developing countries, where financial resources are limited, this system is considered to be a powerful incentive for importing nuclear reactors in combination with BOO contract system that covers from construction to operation. Japan's nuclear reactor exports are planned for the UK, Vietnam, and Turkey. In addition, a nuclear power agreement with India has been agreed in principle, and the order receipt of Japanese power plant manufacturers is expected. (A.O.)

    1995-01-01

    The Royal Institute of Technology in Stockholm provides one third of Sweden's capacity for engineering studies and technical research at the post-high-school level. Altogether, the institute includes about 8000 students and 900 active postgraduate students and has a staff of nearly 2500. The research activities cover a broad spectrum of the natural sciences and technology, as well as architecture, industrial economics, urban planning, work science and environmental technology. In 1993, a Nuclear Technology Centre was established at the institute. The purpose of this Centre is to stimulate education and research in nuclear technology in order to contribute to the preservation and development of competence in the nuclear field. The formation of the Centre should be regarded as one of several recent initiatives aimed at maintaining a high level of safety and reliability in the operation of nuclear power plants at a time when there are political manoeuvres to phase out nuclear energy in Sweden. The paper summarizes the motives that led to the formation of the Centre, its goals and organization, and its initial activities and results. The paper may be of interest to similar organizations in other countries which are also faced with uncertainties regarding the future of existing nuclear power plants or of current programmes, and which consider that co-operation between the industry and universities is an important factor in ensuring the quality of technological development.

    As hydrocarbons have strikingly different properties for neutrons as compared with rocks, neutronic methods are useful to prepare logs of bore holes drilled for petroleum exploration. The earlier neutron logs were based on steady neutron sources, but the superior logs, namely, neutron life time log and neutron induced spectral log are based on pulsed neutron sources. The methods of obtaining these logs, their limitations and the field equipment required are described briefly. As the two logs are complementary, a plea has been made to develop field equipment which can obtain two logs in a single run. (M.G.B.)

    Nuclear power plants are large infrastructure projects that require government support and approval. This paper will highlight and contrast the larger, mostly government-desired, nuclear program localization objectives with the more utility-specific requirements for successful project implementation. Governments are concerned about sustainable industrial development, particularly manufacturing, and job creation while utilities are focused on delivering reliable electricity to consumers at the lowest cost. Numerous countries emphasize local content as a key requirement when procuring a station. For countries like China and Korea that have large programs, their strategy has been to localize to the point of having their own indigenous design. However, developing a workable localization strategy that truly benefits the local economy for others including existing nuclear markets like Canada, the UK, South Africa and Brazil as well as in newly developing markets such as Vietnam and Malaysia is more challenging. These countries may not look to indigenize a new design, rather they would localize elements of the nuclear program that best fit their strengths. The paper will discuss the issues related to developing successful localization and industrialization strategies in a changing nuclear world. (author)

    Bennett, Ralph G.

    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

    The author begins by discussing the history of nuclear power development in the US. He discusses the challenges for nuclear power such as the proliferation of weapons material, waste management, economics, and safety. He then discusses the future for nuclear power, specifically advanced reactor development. People can all be thankful for nuclear power, for it may well be essential to the long term survival of civilization. Within the seeds of its potential for great good, are also the seeds for great harm. People must ensure that it is applied for great good. What is not in question is whether people can live without it, they cannot. United States leadership is crucial in determining how this technology is developed and applied. The size and capability of the United States technical community is decreasing, a trend that cannot be allowed to continue. It is the author's belief that in the future, the need, the vision and the confidence in nuclear power will be restored, but only if the US addresses the immediate challenges.

    Several advanced reactor designs have been so far developed in Russia. The AES-91 and AES-92 plants with the VVER-1000 reactors have been developed at the beginning of 1990. However, the former design has been built in China and the latest which is certified meeting European Utility Requirements is being built in India. Moreover, the model VVER-1500 reactor with 50-60 MWd/t burn-up and an enhanced safety was being developed by Gidropress about 2005, excepting to be completed in 2007. But, this schedule has slipped in favor of development of the AES-2006 power plant incorporating a third-generation standardized VVER-1200 reactor of 1170 MWe. This is an evolutionary development of the well-proven VVER-1000 reactor in the AES-92 plant, with longer life, greater power and efficiency and its lead units are being built at Novovoronezh II, to start operation in 2012-13. Based on Atomenergoproekt declaration, the AES-2006 conforms to both Russian standards and European Utility Requirements. The most important features of the AES-2006 design are mentioned as: a design based on the passive safety systems, double containment, longer plant service life of 50 years with a capacity factor of 92%, longer irreplaceable components service life of 60 years, a 28.6% lower amount of concrete and metal, shorter construction time of 54 months, a Core Damage Frequency of 1x10 -7 / year and lower liquid and solid wastes by 70% and 80% respectively. The presented paper includes a comparative analysis of technological and safety features, economic parameters and environmental impact of the AES-2006 design versus the other western advanced reactors. Since the Bushehr phase II NPP and several other NPPs are planning in Iran, such analysis would be of a great importance

    Taiwan is an island with 22 million inhabitants in an area of 36,000 square kilometers. GNP growth in the past 20 years enjoyed an average annual rate of 72% p.a. The national economy has turned to industry and trade oriented. Energy demand kept at a pace of growth at 5.8% p.a. Energy resource is meager, endowed only with hydro potential of about 5,000 MW and limited coal resources. As high as 96% of the primary energy has to be imported. Energy policy dictates the importance of energy diversification in source and type. Electric power system has been rapidly expanded to 26,684 MW in installed capacity by 1998. Nuclear power generation was first introduced in 1977. In accordance with the development an Atomic Energy Law aiming at peaceful use of nuclear energy was stipulated early in 1968. Manpower needed for planning, design, construction, operation and maintenance has been fostered by stages. Three nuclear power stations, each with two units, totaling 5144 MW, constitute 19.3% of the power system capacity and 24.8% of the total energy generated in 1998. Nuclear power has greatly contributed to the system in lowering the overall generation cost ever since its operation especially during energy crises in 1980s . Four qualified nuclear sites were selected from a number of candidate sites. For the future, 51% p.a. electricity growth is expected. The 4th nuclear project which was approved in 1992 and had ever caused many protests is under construction and has accumulated about 30% completion. However, many people are still concern the nuclear safety and radioactive waste treatment. After implementing intense communication programs. Most of the people are convinced that nuclear power is safe, clean, and economical. Opinion polls conducted in recent years showed steadily that about 55-60% of the interviewees were in favor of nuclear power, and 20-30% were against nuclear power. However right after the accidental blackout due to the 921 catastrophic earthquake in Sept

  20. Development of a nuclear fuel cycle transparency framework

    2005-01-01

    Nuclear fuel cycle transparency can be defined as a confidence building approach among political entities to ensure civilian nuclear facilities are not being used for the development of nuclear weapons. Transparency concepts facilitate the transfer of nuclear technology, as the current international political climate indicates a need for increased methods of assuring non-proliferation. This research develops a system which will augment current non-proliferation assessment activities undertaken by U.S. and international regulatory agencies. It will support the export of nuclear technologies, as well as the design and construction of Gen. IV energy systems. Additionally, the framework developed by this research will provide feedback to cooperating parties, thus ensuring full transparency of a nuclear fuel cycle. As fuel handling activities become increasingly automated, proliferation or diversion potential of nuclear material still needs to be assessed. However, with increased automation, there exists a vast amount of process data to be monitored. By designing a system that monitors process data continuously, and compares this data to declared process information and plant designs, a faster and more efficient assessment of proliferation risk can be made. Figure 1 provides an illustration of the transparency framework that has been developed. As shown in the figure, real-time process data is collected at the fuel cycle facility; a reactor, a fabrication plant, or a recycle facility, etc. Data is sent to the monitoring organization and is assessed for proliferation risk. Analysis and recommendations are made to cooperating parties, and feedback is provided to the facility. The analysis of proliferation risk is based on the following factors: (1) Material attractiveness: the quantification of factors relevant to the proliferation risk of a certain material (e.g., highly enriched Pu-239 is more attractive than that of lower enrichment) (2) The static (baseline) risk: the

    The coal is the main primary energy source in China. In spite of the economic development, the coal consumption decreases regularly since the last years. It is the consequences of the energy policy of China which closed little coal mines of poor productivity. The today energy balance of China lays on two supplying sources: 70 % coal and 24 % hydro energy. To face the increasing economic development China will need a complementary electric power production source. In this context, this document presents the today nuclear energy situation in the chinese energy policy, the perspectives for the french nuclear industry and the possible chinese-french collaboration.

    2010-01-01

    This essay assesses North Korea's long-standing quest for nuclear weapons; alternative strategies for inhibiting Pyongyang's weapons development; and the potential implications for regional security and nonproliferation should the Democratic People's Republic of Korea (DPRK) retain and enhance its weapons programs. North Korea's pursuit of a nuclear weapons capability has long provoked heated debate among policy makers and research analysts about the purposes of engagement with the North, reflecting the repeated frustrations in efforts to negotiate Korean denuclearization. These debates reflect widely divergent views of the North Korean regime; its sustainability as an autonomous political, economic, and military system; and the potential consequences of continued nuclear development in this isolated, highly idiosyncratic state. These questions assume additional salience as North Korea approaches a leadership succession for only the second time in its six-decade history. The effort to inhibit North Korea's pursuit of nuclear weapons is among the longest running and least successful sagas in international security and non-proliferation policy of the past quarter century. In early 2010, Pyongyang claims a rudimentary nuclear capability by possession of weaponized plutonium, the conduct of two nuclear tests, and advances in the production of enriched uranium as an alternative means of fissile material production, though the latter step is nominally justified as a source for reactor fuel. North Korea defends its pursuit of a nuclear deterrent to counter what Pyongyang deems existential threats posed by the United States.Despite the resumption of high-level diplomatic contact between Washington and Pyongyang in late 2009, realization of a non-nuclear Korean Peninsula remains a very remote prospect. The DPRK insists that a peace agreement between the U.S. and North Korea and hence the cessation of 'hostile DPRK-U.S. relations' are necessary before any consideration of

    Gamma spectroscopy uses semiconductors of atomic number as high as possible. Until recently germanium only was used, in devices of N-I-P structure (P-doped - intrinsic N - doped region) which had to be used and kept at low temperature; germanium detectors of NP structure have now been developed and have the advantage that they can be kept at room temperature. However germanium is not the ideal material for all applications and many laboratories are now studying cadmium telluride and mercuric iodide detectors [fr

    Through the effort of deliberation and legislation over five years, Japanese government structure was reformed this January, with the aim of realizing simple, efficient and transparent administration. Under the reform, the Agency for Nuclear and Industrial Safety (ANIS) was founded in the Ministry of Economy, Trade and Industry (METI) to be responsible for safety regulation of energy-related nuclear activities, including nuclear fuel cycle activities, and industrial activities, including explosives, high-pressure gasses and mining. As one of the lessons learned from the JCO criticality accident of September 1999, it was pointed out that the government's inspection function was not enough for fuel fabrication facilities. Accordingly, new statutory regulatory activities were introduced, namely, inspection of observance of safety rules and procedures for all kinds of nuclear operators and periodic inspection of fuel fabrication facilities. In addition, in order to cope with insufficient safety education and training of workers in nuclear facilities, licensees of nuclear facilities are required by law to specify safety education and training for their workers. ANIS is committed to enforce these new regulatory activities effectively and efficiently. In addition, it is going to be prepared, in its capacity as safety regulatory authority, for future development of Japanese fuel cycle activities, including commissioning of JNFL Rokkasho reprocessing plant and possible application for licenses for JNFL MOX fabrication plant and for spent fuel interim storage facilities.

    Statistical and prognostic data were compared characterizing the development of the power industry, electric power generation and nuclear power in the CSSR and in other European countries. The penetration of nuclear power into the power industry of the individual countries is affected especially by the economic necessity of changing the level and structure of the respective country's national economy with primary power resources and electric power. The analysis shows among others that nuclear energy has become most widely introduced in countries where electric power makes up a high proportion of the power balance and where the country only has an average amount of primary power resources. By the year 2000 nuclear power is envisaged to make up 27.5 to 32.2% of total power output which corresponds to an annual increase of 5.6% in the power output of nuclear power plants. The dependence of Czechoslovakia's increase of power output on nuclear power is greater than that of both the European capitalist and socialist countries. (Z.M.). 1 fig., 4 tabs., 5 refs

    Is the nuclear power an ethical alternative for the development of the energy sector? This is the question the authors try to answer. Nuclear power is subject to constant attacks from different opponent groups. They have managed to make negative public opinion, especially after the Chernobyl accident, which tends to minimise the important of that alternative. Unfortunately, nuclear professionals are also the subjects of that propaganda and even some of us are pessimistic about the future of our sector. The public will accept nuclear power if the producer guarantees that he is able to meet three conditions for the electricity supply: generation without risks for public or the environment, as cost-effective as possible and with high availability. In order to keep the confidence of general public for nuclear power, the authors, with total openness, compared the up-to-date power alternatives. The conclusion is, that for the next future, to avoid the global heating effect and to meet the constrains for a 'cleaner world', the humanity must to rely on nuclear power, besides other cleaner conventional alternatives, as ethical sources of energy.

  16. Accelerated Nuclear Energy Materials Development with Multiple Ion Beams

    2009-08-19

    A fundamental issue in nuclear energy is the changes in material properties as a consequence of time, temperature, and neutron fluence. Usually, candidate materials for nuclear energy applications are tested in nuclear reactors to understand and model the changes that arise from a combination of atomic displacements, helium and hydrogen production, and other nuclear transmutations (e.g. fission and the production of fission products). Experiments may be carried out under neutron irradiation conditions in existing nuclear materials test reactors (at rates of 10 to 20 displacements per atom (DPA) per year or burn-up rates of a few percent per year for fertile fuels), but such an approach takes much too long for many high neutron fluence scenarios (300 DPA for example) expected in reactors of the next generation. Indeed it is reasonable to say that there are no neutron sources available today to accomplish sufficiently rapid accelerated aging let alone also provide the temperature and spectral characteristics of future fast spectrum nuclear energy systems (fusion and fission both). Consequently, materials research and development progress continues to be severely limited by this bottleneck.

    A reliable power supply is necessary for Russia to find its way out of the present crisis and to develop its economy. Although there are considerable fossil fuel resources in Russia, they are not sufficient to meet future power demands. Forecasts by specialists indicate that about 30% of the necessary increase in annual electricity production should be covered until the year 2010 by new nuclear power plants (NPPs). Also, by that time, all outdated nuclear power units should be replaced by new plants of more than 8 GW capacity. The total NPP capacity in Russia should be increased until 2010 by 50-70%, thus providing the basis for further development of nuclear power, with the aim of reaching 25% of the total electricity generation before 2015. Safety assurance of operational NPPs is a major prerequisite for nuclear power development, and measures for improving safety are being implemented. New designs of power units are being developed, in accordance with modern requirements and safety standards, and the start of construction of these units is planned for the end of this decade. The economic parameters of NPPs situated in the European part of Russia are better than those of coal and gas fuelled power plants. The improved safety of NPPs, the implementation of measures for processing and storage of radioactive wastes, and economic arguments are gradually changing the negative attitude of the population to nuclear power. Extended international co-operation is a further important factor, giving additional assurances of successful and safe nuclear power development in Russia. (author). 1 tab

    West, J.B.

    1980-01-01

    A digital mineral logging system acquires data from a mineral logging tool passing through a borehole and transmits the data uphole to an electronic digital signal processor. A predetermined combination of sensors, including a deviometer, is located in a logging tool for the acquisition of the desired data as the logging tool is raised from the borehole. Sensor data in analog format is converted in the logging tool to a digital format and periodically batch transmitted to the surface at a predetermined sampling rate. An identification code is provided for each mineral logging tool, and the code is transmitted to the surface along with the sensor data. The self-identifying tool code is transmitted to the digital signal processor to identify the code against a stored list of the range of numbers assigned to that type of tool. The data is transmitted up the d-c power lines of the tool by a frequency shift key transmission technique. At the surface, a frequency shift key demodulation unit transmits the decoupled data to an asynchronous receiver interfaced to the electronic digital signal processor. During a recording phase, the signals from the logging tool are read by the electronic digital signal processor and stored for later processing. During a calculating phase, the stored data is processed by the digital signal processor and the results are outputted to a printer or plotter, or both
