Pitfalls in current design requirements

It is illogical to continue using some current design requirements in their present form. Specifying design criteria to guard against various occurrences while neglecting an examination of their likelihood is unjustifiable. Probabilistic analyses, followed if necessary by cost-benefit analyses, can focus on and bring into perspective various adverse implications resulting from some deterministic criteria and requirements. Proper use and probabilistic analysis techniques will give system designers latitude in design decisions, thereby eliminating the built-in biases of design philosophy based on deterministic criteria. This resultant philosophical diversity applied to attaining design goals should be beneficial in reducing risks from nuclear stations
