Evolution of CANDU Balance of Plants System

This paper describes how the design process adopted in Canada to achieve high plant availability also provides a mechanism for this design and supply flexibility in B/P. The topics covered are: Some important features of B/P design in CANDU units that contribute to high availability. The development of interface requirements between Nuclear Steam Plant and B/P, and their use. Probabilistic Safety assessment method to assure achievement of safety goals in B/P design
