Bruce B Risk Assessment: Results and Applications

Abstract

This paper describes the major results of the recently-completed Bruce B Risk Assessment (BBRA). 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. Also discussed are the key conclusions of the assessment. The paper also discusses how the products of the study have been used to support decision-making at the plant. Some specific examples are included. The paper concludes by describing the work undertaken to develop an on-line risk model that is being used on a regular basis by plant personnel to assess the risk impact of changes in plant configuration.
