Lessons Learned from 21 Nuclear Plant Probabilistic Risk Assessments

Publication Date Aug 23, 1988 by Garrick B.J.

In the short time that plant-specific, full-scope probabilistic risk assessments (PRAs) have been performed, extensive progress has been made in understanding and managing risk.

After performing over 20 PRAs, one of the most impressive lessons is that quantitative risk management is tedious and hard work. It requires great attention to plant details and all the resources involved. including procedures, training, maintenance, quality control, staffing. engineering support, and, of course, a detailed knowledge of the plant, its systems, and the way they operate and interact.
