The Application of Probabilistic Risk Assessments in Demonstrating the Adequacy of Safety in the Design of Nuclear Chemical Plants Available to Purchase

The Reprocessing Engineering Division of British Nuclear Fuels undertakes the design of nuclear chemical plants for construction and subsequent operation at the Sellafield Works of the Reprocessing Operations Division. Plant construction cannot take place until it has been demonstrated that the chosen design will allow the plant to operate in an adequately safe manner, corresponding to an extremely low level of risk. Risk, or the cumulative frequency and consequences of all potential hazards, is evaluated by means of probabilistic risk assessments (PRA).
