Re: Attempting to bring clarity to the nuclear problems facing Japan


Hey Phil,  Thanks for sharing your knowledge about nuclear reactor designs.  Being curious from reading your post, I see on Wikipedia that the new reactors 3 and 4 at Plant Vogtle will indeed be the Westinghouse AP 1000s. But what about the existing 1 & 2 reactors, which are mentioned briefly as Westinghouse PWRs (pressurized water reactor).  Would you please explain the differences between these two designs?  And what is your opinion on the safety of the PWR? 

Cheers, John
