NEA-1703 ZZ-VITENEA-J.

1. NAME OR DESIGNATION:  ZZ-VITENEA-J.

3. DESCRIPTION OF PROGRAM OR FUNCTION

VITENEA-J is a coupled multigroup cross section library in the standard VITAMIN-J energy group structure (175 n + 42 gamma) in AMPX format produced by ENEA-Bologna for nuclear fusion applications.It is based on nuclear data from the general purpose Fusion Evaluated Nuclear Data Library (FENDL/E-2.0) and ENDF-B/VI. This library has been widely used by ENEA group in neutron/gamma transport calculations for ITER safety assessment via the SCALENEA-1 multipurpose Sn calculation sequence.

4. METHODS

The data have been prepared by processing basic nuclear data into a fine group problem independent format through an automatic calculation procedure using the modules of NJOY-94.105 and AMPX-77 Processing Systems. The translation of the multigroup data from the GENDF format produced by NJOY to the AMPX Master Library format was performed by means of the AMPX-77 SMILER module.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The library contains 75 nuclides. Seventy nuclides were processed at four temperatures (300 K, 600 K, 900 K, 1500 K) at ten values for the background cross section s0. Thermal scattering cross sections were processed at the three temperatures (296 K, 600 K, 1200 K) available in the ENDF-B/VI thermal scattering law data file for four additional bound nuclides (H-1 in water, C in graphite, Be in beryllium metal and oxide).

6. TYPICAL RUNNING TIME:  Machine dependent.

7. UNUSUAL FEATURES

The material characterized by MAT=900 has been added in the library. It contains the ANSI standard neutron/gamma flux to dose rate factors, in the 175n and 42 gamma group structure, to be used for dose rate calculations.

8. RELATED OR AUXILIARY PROGRAMS:  NJOY, AMPX, SCALE, SCAMPI, DORT, TORT.
