Probabilistic Risk Assessment of disassembly procedures
Probabilistic Risk (Safety) Assessment (PRA or PSA) is an analytic methodology for identifying the combination of events that, if they occur, lead to accidents. Accidents are defined as those events causing loss or injury to people, property, or the environment. PRA also provides a method for estimating the frequency of occurrence of each combination of events and the consequences of each accident. The Los Alamos effort for this study is summarized as follows: The focus of the Los Alamos study was on evaluating the risks specifically associated with disassembling a Los Alamos-designed device. The PRA for the disassembly operation included a detailed evaluation only for those potential accident sequences which could lead to significant off-site consequences and affect public health. The overall purpose of this study was to investigate the feasibility of a risk consequence goal for DOE operations. Often called a Level 3 PRA (or PSA), the methods are general and can with a little modification be applied to other procedures or processes.
