An inherently safe reactor, in theory, would be designed, operated, and monitored in such a way that the reactor would never be damaged and, as a result, no radioactivity would ever be released to the environment. No such reactor currently exists. The risk from existing reactors is so real and so large that liability insurance from private companies is financially impossible, thereby requiring federal liability protection
The catalog of reactor problems, near misses, forced shutdowns, and spotty safety records is eye opening and a clear indication of the nature of the beast.
