DOI: 10.1051/ndata:07384 The nonelastic reaction code BRIEFF and its intranuclear cascade BRIC

Abstract. The intranuclear cascade (INC) code of Bruyères-le-Châtel named BRIC is the first part of the nonelastic reaction code BRIEFF. Recent changes in our INC are presented. They were done for nucleon induced reaction to improve results below 100 MeV, and to calculate cross sections of compound nucleus formation. These cross sections are used in the evaporation component of our reaction code. BRIEFF is included in the Bruyères-le-Châtel version of HETC to perform thick targets calculations. BRIC has recently been incorporated into MCNPX 2.4.0 to verify thick target results of neutron yields and to do some comparisons with other nuclear models or libraries. Good agreement with data is obtained on average.
