A Study of New Risk Metrics for Non-Light Water Small Modular Reactor
Korea Atomic Energy Research Institute, Korea.
ABSTRACT
Since it is not suitable to use risk metric such as core damage frequency, for non-light water small modular reactors, other risk metrics are necessary to show the effects of safety improvement. Several risk metrics are suggested, and their usefulness is discussed by an illustrative example, in which the safety improvement by choosing a longer emergency planning zone is represented by the new risk metrics.
Keywords: Risk metrics, Non-light water reactor, Emergency planning zone, Small modular reactor.
