RSICC DATA PACKAGE DLC-238
1. NAME AND TITLE OF DATA LIBRARY
VITENEA-J: AMPX 175-n,42-g Multigroup X-section Library for Nuclear Fusion Applications.
2. NAME AND TITLE OF DATA RETRIEVAL PROGRAMS
AIM: Convert AMPX master card-image data to binary format. AIM is not included but is distributed in AMPX, SCALE and SCAMPI packages.
ENEA – FIS-MET, Bologna, Italy, and Bologna University, Physics Department, Italy, through the OECD Nuclear Energy Agency Data Bank, Issy-Les Molineaux, France.
4. HISTORICAL BACKGROUND AND INFORMATION
VITENEA-J is a coupled multigroup cross section library in the standard VITAMIN-J energy group structure (175 neutron + 42 gamma) in AMPX master library format produced by ENEA-Bologna for nuclear fusion applications.
5. APPLICATION OF THE DATA
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.
6. SOURCE AND SCOPE OF DATA
It is based on nuclear data from the general purpose Fusion Evaluated Nuclear Data Library (FENDL/E-2.0) and ENDF-B/VI. The data were 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.
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).
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.

7. DISCUSSION OF THE DATA RETRIEVAL PROGRAM
The library is in AMPX Master Library fido free format. It is suitable for direct use in the AMPX, SCALE and SCAMPI Systems. The library has been checked with the SCAMPI module RADE and translated to binary format with AIM. The output of the ALE module is included which lists the main features of the library.
8. DATA FORMAT AND COMPUTER
Card images in AMPX master library format; all computers (D00238/MNYCP/00).
This is the same package that the NEADB distributes as NEA-1703/01.
