Safety goals and decision processes

There is general agreement that harmoniiation of approaches to the safety of future NPPs should include a consistent and stable understanding of what constitutes an acceptable level of nuclear safety, i.e., How safe is safe enough . The Technical Committee agreed that the answer to this question should be derived from public health and safety policies that are applied fairly to all sources of risk on a non-discriminatory basis. 

Future plants are designed to assure high confidence in licensability, of both the design itself, and of the operational aspects that are approved separately. 

Balance among PSA, deterministic methods, and engineering judgement 

The process for evaluating specific designs involves a careful balance of deterministic methods, probabilistic methods (including comparison to numerical safety targets), and the use of engineering judgment. 

This balanced process is comprehensive in its review of the relevant operating experience, test information, etc. and both the plant PSA and the plant s deterministic criteria are reviewed for completeness of scope and completeness of plant state coverage (e.g., low power and shutdown states).
