This report describes calculations carried out with RELAP5/MOD2 on LOBI experiment BT-12, a large steam line break. The following sensitivity studies were performed: heat losses on the intact steam generator; discharge coefficient at break; water in steam lines; nearly implicit numerics. Qualitatively the general trends of BT-12 were predicted well, in particular the timing of events was fairly accurate.
