Under contract to the US Nuclear Regulatory Commission, Sandia National Laboratories (SNL) is performing a state-of-the-art Level 3 Probabilistic Risk Analysis of LaSalle Unit 2, a BWR5 with a Mark II containment. Results obtained to data from the Level 1 internal, fire, flood, and seismic analyses indicate the characteristics of dominant accident sequences and reveal distinct advantages to the integrated systems-analysis approach being employed. The extension of an integrated methodology to the accident progression, source term and consequence analyses will permit a quantitative treatment of uncertainties in Level 3 risk measures arising from all stages of the PRA. A simplified version of these methods has been adopted for the NUREG-1150 PRAs. 7 refs., 1 fig.
