Interim results of the accident sequence evaluation program (ASEP). [PWR; BWR]

This paper highlights the interim results of ASEP. ASEP is one of many programs sponsored by the Nuclear Regulatory Commission (NRC) to study various aspects of severe core damage accidents. The results of ASEP will ultimately focus on identifying the most likely accident sequences and the high risk accident sequences for most light water reactors (LWRs). Major design and operational differences among plants will be accounted for. The factors contributing to the likelihood or risk dominance of the above sequences will also be identified.
