The book combines the key features of multi-unit risk assessment in one resource, reviewing the practices adopted in various countries around the globe to exemplify the dependencies between units on a site. These dependencies include multi-unit interactions, environmental stresses, the sharing of systems, and the sharing of human resource in a control room, factors which can all introduce an increase potential for heightened accident conditions. This book helps readers systematically identify events and evaluate techniques of possible accident outcomes within multi-units. It serves as a ready reference for PSA analysts in identifying a suitable site and the sharing of resources, while carrying out multi-unit risk assessments to ensure the safety of the public and the environment. It will also be valuable for nuclear researchers, designers and regulators of nuclear power plants, nuclear regulatory agencies, PSA engineers and practicing safety professionals.
- Provides a framework for nuclear and PSA researchers and professionals on the design and operation of multi-unit risk assessments
- Reviews practices adopted in various regions around the globe to analyze dependencies between units
- Includes modeling techniques of inter-connections and shared resources, as well as risk aggregation
PSA engineers, nuclear engineers in multi-unit PSA, Nuclear plant designers, nuclear R&D institutions, utility companies, nuclear regulatory agencies, graduate students and academics on nuclear/reliability engineering courses, safety professionals
