National Nuclear Data Organizations

The difficulty of modern nuclear data evaluation, together with the requirements for quality control, revision control, peer review, and data testing that result from the goal of using the data files for calculations that could have major impacts on public health and safety, has led to putting all modern nuclear data evaluation work under the control of a few national and international agencies, including:
  • The Cross Section Evaluation Working Group (CSEWG), which handles the US ENDF/B libraries and the ENDF format. It is coordinated through the National Nuclear Data Center at the Brookhaven National Laboratory.

  • The JEF and EFF Working Groups, now merged as the JEFF Working Group, which handles the Joint European File (JEF), the European Fusion File (EFF), and their forthcoming merger, JEFF. It is coordinated through the NEA Data Bank, a part of the Nuclear Energy Agency (NEA) of the Organization for Economic Cooperation and Development (OECD).

  • The Japanese Nuclear Data Committee (JNDC), which handles the Japanese Evaluated Nuclear Data Library (JENDL). It is coordinated through the Nuclear Data Center at the Japan Atomic Energy Agency (JAEA).

Each of these organizations has adopted the ENDF-6 format as the common method for publishing their nuclear data libraries, but each has been able to define its own procedures for using the formats, reviewing the evaluations, and testing the results.
