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.
