This report describes the results of a series of calculations conducted to investigate the response of BWR Mark 3 containments to short-term station blackout severe accident sequences. The BWR-LTAS, BWRSAR, and MELCOR codes were employed to conduct quantitative accident sequence progression and containment response analyses for several station blackout scenarios. The accident mitigation effectiveness of containment venting and backup emergency power for containment hydrogen ignitors and drywell vacuum breakers is assessed. 18 refs., 142 figs., 12 tabs.
