A Primer on Nuclear Safety:2.4 Defense in DepthA Brief Note on ESBWR SafetyHow Safe is the ESBWR? Given a probabalistic approach to nuclear safety, we first note that the ESBWR designers GE has estimated that a likelihood of core meltdown every 29 million years. But a core meltdown is far from a release of a large amount of radiation from the reactor into the environment. Thus we must look at the likelihood of a failure of not only the presser vessel, but of the core catcher, a system designed to trap and contain molten material from the core and to prevent its movement out side the reactor...
