[QUOTE="backhoeboogie, post: 821924, member: 3162"] TB I have worked on PWRs. I have been sent out on a few BWRs but it was mostly instrumentation related. I know very little reactor theory when it comes to BWRs. Fission is fission. Borated water is a moderator that kills the chain reaction. Emergency Response Organizations have a series of classifications for events. The least of which is a Notification of an Unusual Event. It escalates up from there. A series of Technical Specifications are used to classify events and it applies to both PWRs and BWRs. The classifications I am hearing out of Japan follow the Tech Specs I am familiar with. Chernobyl was not a GE design. There again, I am more familiar with Westinghouse designs. I have been to school for reactor theory and do understand it to a very high degree. I do not operate the plants for a living. My engineering organization is rather the first call from the control room when anything goes amiss and it usually does not involve the reactor vessel itself or safety features although back up systems do occasionally have anomolies. That is why we have redundant trains and systems. Everything is backed up by a back up system. And yes we are designed for seismic events (earthquakes). [/QUOTE]
