This presentation describes the major results of the recently completed Bruce B Risk Assessment (BBRA) study. The results are presented in the form of the frequencies of various fuel damage categories (FDCs) and ex-plant release categories (EPRCs). Some of the dominant sequences leading to these categories are discussed. The key findings of the study will be presented.

The presentation also explains how the products of the study have been used to support decision-making at the plant. Some specific examples are included. The seminar concludes by describing the work undertaken to develop an on-line BBRA model that will enable plant personnel to assess the risk impact of day-to-day operations and maintenance.
