The successful development of advanced nuclear systems for sustainable energy production depends on highlevel modelling capabilities for the reliable and cost-effective design and safety assessment of such systems, and for the interpretation of key benchmark experiments needed for performance and safety evaluations. Highquality nuclear data, in particular complete and accurate information about the nuclear reactions taking place in advanced reactors and the fuel cycle, are an essential component of such modelling capabilities. In the CANDIDE project, nuclear data needs for sustainable nuclear energy production and waste management have been analyzed and categorized, on the basis of preliminary design studies of innovative systems. Meeting those needs will require that the quality of nuclear data files be considerably improved. The CANDIDE project has produced a set of recommendations...

The most common nuclear data formats are supported, and data originating from the major evaluated libraries, such as JEFF, JENDL, ENDF/B, CENDL etc., can be displayed, computed, and compared together and with experimental reaction data from the EXFOR database. In addition, various navigation and search tools are available to explore the nuclear databases. The JANIS software can be used either as a standalone application or directly from the web at www.nea.fr/janis. This software has developed into a popular tool among students and researchers working with nuclear data. Features included in the latest releas...

The world-wide network of nuclear reaction data centres (NRDC) has, for about 40 years, provided data services to the scientific community. This network covers all types of nuclear reaction data, including neutron-induced, charged-particle-induced, and photonuclear data, used in a wide range of applications, such as fission reactors, accelerator driven systems, fusion facilities, nuclear medicine, materials analysis, environmental monitoring, and basic research. The now 13 nuclear data centres included in the NRDC are dividing the efforts of compilation and distribution for particular types of reactions and/or geographic regions all over the world. A central activity of the network is the collection and compilation of experimental nuclear reaction data and the related bibliographic information in the EXFOR and CINDA databases. Many of the individual data centres also distribute other types of nuclear data information, including evaluated data libraries, nuclear structure a...

These parameters are the main performance indicators of the success of fusion experiments, and traditionally they have been determined with neutron yield monitors such as fission chambers or silicon diodes calibrated with activation systems [1]. Such yield monitors have been installed and successfully used in most fusion experiments including JET. A substantial fraction of the neutron flux reaching the activation system is due to scattered neutrons, so the yield calibration relies on neutron transport calculations. These calculations contribute to the involved uncertainties, which will increase with the size of the fusion device and hence constitute a problem in burning plasma machines such as ITER. For these reasons, a new independent method for the absolute determination of the neutron rate has been developed, based on the measurement of the direct neutron flux with a high-resolutio n spectrometer. The measurement of the direct neutron flux makes it possible to quantify the uncertainty. The new method is based on an absolute neutron flux measurement and does not require any cross-calibration with other neutron systems. In a fusion plasma of mixed deuterium (D) and tritium (T), both 2.5-MeV neutrons

One of the WPEC objectives is to assess needs for nuclear data improvements and to stimulate initiatives to fulfill these. The High Priority Request List (HPRL) was established in pursuit of this objective. The HPRL project aims at identifying accuracy targets for the improvement of nuclear data, primarily for application in the nuclear industry. The list therefore provides a guide for those planning new measurements, nuclear model calculations and data evaluation programmes. Since 2004, the HPRL has undergone a major overhaul to better guarantee timeliness and adequate documentation of requests. A new webpage was developed at the NEA to facilitate submission of new requests, and to allow easy inspection. Submitted requests are first reviewed by external referees, before being accepted on the list. Requests are divided into high priority requests, where a quantitative justification is provided and general requests for which the justification is qualitative. The relevance of requests for nuclear energy applications is ensured through periodic reviews by an expert group of the NEA WPEC, involving Europe (JEFF), Japan (JENDL), the United States (ENDF), Russia (BROND) and China (CENDL). The new procedures for submission, review and adoption of requests were recently validated with a first set of entries. Examples of recent updates to the HPRL project are presented. The requirements for providing new requests are also presented, as well as how to justify needs for new nuclear data. Data users around the world are encouraged to formulate their concerns about nuclear data and submit them to the HPRL. The HPRL is maintained by the NEA Data

This implies optimal incineration of all actinides that nowadays constitute spent nuclear fuel, in critical and sub-critical reactors. As a consequence, the scope of the CA encompasses transmutation in fast critical reactors as well as sub-critical systems (ADS). The purpose is to identify the needs for improved nuclear data, assess the present status of knowledge, and to estimate what accuracy can be reached with state-of-the-art techniques.
