OECD NEA データバンクの現状 - 核データとコンピュータプログラムサービスを中心に

The Organisation for Economic Cooperation and Development (OECD) Nuclear Energy Agency (NEA) Data Bank (DB) is responsible for the coordination of the Joint Evaluated Fission and Fusion (JEFF) Nuclear Data Library project, which is a collaboration between NEA Data Bank participating countries. The JEFF library combines the efforts of its participating institutions to produce sets of evaluated nuclear data, for fission and fusion applications, and is mostly used as one of the reference evaluated nuclear data library of many European countries, in particular by the French nuclear industry. Besides the Nuclear Data Services (NDS), the Computer Program Services (CPS) of the DB is in charge of providing direct services to the end users by collecting and disseminating computer programs in the Data Bank participating countries and organising training courses on the most widely used codes. The DB also supports other Standing Technical Committees (STC) of the NEA. For example, the DB has been developing the Thermochemical Database (TDB) Project since 1984 following the recommendation of the NEA Radioactive Waste Management Committee (RWMC) on the need of a database of high-quality thermochemical data for species relevant to performance assessments of deep geological repositories.

This presentation will focus on the status of NDS activities and its new strategy following the release of the latest JEFF library, i.e., JEFF-3.3 in 2017. Additionally, other topics under the Data Bank scope of activities will be presented, notably the new computer code licensing framework, i.e., the Data Bank Single User (SUL) licence.The presentation will also be the opportunity to adress any comments and questions related to the services of the Data Bank.
