[en] Nuclear Energy Data is the OECD Nuclear Energy Agency's annual compilation of statistics and country reports documenting nuclear power status in the OECD area. Information provided by member country governments includes statistics on installed generating capacity, total electricity produced by all sources and by nuclear power, nuclear energy policies and fuel cycle developments, as well as projected generating capacity and electricity production to 2035, where available. Total electricity generation at nuclear power plants and the share of electricity production from nuclear power plants increased slightly in 2014, by 1.4% and 0.3% respectively, despite Japan's nuclear fleet remaining offline throughout the year. No new reactor was connected to the grid in OECD countries and one, in the United States, was permanently shut down. Governments committed to having nuclear power in the energy mix advanced plans for developing or increasing nuclear generating capacity, with the preparation of new build projects making progress in Finland, Hungary, Turkey and the United Kingdom. Further details on these and other developments are provided in the publication's numerous tables, graphs and country reports. This publication contains 'StatLinks'. For each StatLink, the reader will find a URL which leads to the corresponding spreadsheet. These links work in the same way as an Internet link. (authors)

[en] Nuclear Energy Data is the Nuclear Energy Agency's annual compilation of statistics and country reports documenting nuclear power status in NEA member countries and in the OECD area. Information provided by governments includes statistics on total electricity produced by all sources and by nuclear power, fuel cycle capacities and requirements, and projections to 2035, where available. Country reports summarise energy policies, updates of the status in nuclear energy programmes and fuel cycle developments. In 2017, nuclear power continued to supply significant amounts of low-carbon base-load electricity, in a context of strong competition from low-cost fossil fuels and renewable energy sources. Governments committed to having nuclear power in the energy mix advanced plans for developing or increasing nuclear generating capacity, with the preparation of new build projects making progress in Finland, Hungary, Turkey and the United Kingdom.

[en] Most MCNP standard neutron ACE libraries are processed at room temperature, 293,6 deg K. The temperature enters into the processing of the evaluation of a data file through the Doppler broadening of cross-sections. The nuclear fuel burnup usually takes place at reactor core temperatures much higher than room temperature, consequently, Monte Carlo burnup calculations should not only use the best cross-sections evaluations available but also use evaluations that are at temperatures approximating the temperatures of the application. In order to face the scarcity of temperature dependent MCNP cross-sections data to most isotopes, CDTN is developing an in-house temperature dependent neutron library for those nuclides commonly necessary in the systems simulated for the ongoing projects demanding Monte Carlo burnup. This paper describes the data processing of the ENDF/B-VI, release 8, using the NJOY99 code, towards provides this temperature dependent ACE library. Up to now fifty one elements and isotopes of the materials uranium oxide, thorium oxide, zircaloy-4, stainless steel AISI-348, light water, boron carbide and the silver-indium-cadmium alloy were processed at temperatures range from 293,6 deg K to 1200 deg K. Some benchmarks for thorium cycle described in the 'OECD/NEA International Handbook of Evaluated Criticality Safety Benchmark Experiments' were simulated using MCNP5 and the data set of this in-house library and the results usually agree with those obtained for the .60c standard MCNP neutron library for room temperature.

[en] Approximate expenditure values for plutonium extraction from irradiated nuclear fuel of fast and thermal reactors when uranium and plutonium are the main products upon regeneration are determined. The given formulae allow the estimation to be carried out. It is found that plutonium extraction from the fuel elements of thermal reactors with slag accumulation σsub(slag)=14 kg/t and its reuse in the same reactors is profitable with chemical reprocessing cost up to 200 dol/kg of fuel. With the increase of the slag accumulation from 14 up 42 kg/t the permissible expenditure value of chemical reprocessing amounts to 300 dol/kg the fuel. Chemical reprocessing of the fast reactor fuel is profitable for all cosidered expenditures on regeneration and extracted plutonium cost is thrice as less as upon the fuel reprocessing from thermal reactors

[en] Since 1990, one of the most interesting developments in the field of nuclear data for nuclear technology applications is that several new evaluated data files have been finalized and made available to the International Atomic Energy Agency (IAEA) for distribution to its Member States. Improved evaluated nuclear data libraries such as ENDF/B-VI from the United States and JENDL-3 from Japan were developed over a period of 10-15 years. This report is not an evaluation of the evaluations. The report as presented here gives a first look at the cross section line shapes of the isotopes that are important to the thorium fuel cycle derived from the two recently evaluated data files: JENDL-3 and ENDF/B-VI. The basic evaluated data files JENDL-3 and ENDF/B-VI were point-processed successfully using the codes LINEAR and RECENT. The point data were multigrouped in three different group structures using the GROUPIE code. Graphs of intercomparisons of cross section line shapes of JENDL-3 and ENDF/B-VI are presented in this paper for the following isotopes of major interest to studies of the thorium fuel cycle: ²³⁰Th, ²³²Th, ²³¹Pa, ²³³Pa, ²³²U, ²³³U and ²³⁴U. Comparisons between JENDL-3 and ENDF/B-VI which were performed at the point and group levels show large discrepancies in various cross sections. We conclude this report with a general remark that it is necessary to perform sensitivity studies to assess the impacts of the discrepancies between the two different sets of data on calculated reactor design and safety parameters of specific reactor systems and, based on the results of such sensitivity studies, to undertake new tasks of evaluations.
