Weaver, W W

A question frequently posed by plant personnel is how to make the best use of a completed probabilistic risk assessment (PRA). A proposed methodology is presented here. Its utility is illustrated by performing an analysis with the preliminary results of the TMI-1 PRA. An initial step in formulating a theoretic decision is determination of the appropriate criteria upon which the decision is to be based. A straightforward approach makes use of two basic criteria: risk reduction in terms of core melt frequency (i.e., the US Nuclear Regulatory Commission has expressed a value of 1 x 10/sup -4//reactor-yr as the goal) and present value (PV) dollars. The methodology presented is similar to a quantified cost/benefit study. It can be used in conjunction with results from any completed PRA or system reliability analyses.
