Type of Reactors going to be built?
B.PRESGROVE:
Ok, so why are the EPR reactors looked down on. I saw in another thread where they are compared to a throw back to the 70's style reactors and there were two places mentioned, I guess accidents happened there? In yalls humble opinion which type of reactors would be the best to build?
Fermi2:
Because EPR are from the old style of thinking where safety features are active, ie pumps have to start, valves have to stroke, items like that. The next Gen Reactors rely on more passive systems such as accumulators and the laws of physics to perform safety functions. This means less piping, less wired and more important less connections to the reactor.
Given there's operating experience with only one type of Advanced Reactor that being the ABWR I guess I'd give it the nod. Theoretically the Westinghouse AP 1000 and ESBWR would be just as good if not better.

Per the NRC's web page on new reactors ( http://www.nrc.gov/reactors/new-reactor-licensing.html ), TVA is planning on building 2 AP1000's at Bellefonte. Vogtle is also getting 2 AP1000's.

The only new units planned to be ABWR's (so far) are South Texas 3 and 4.
Two 4 loop Westinghouse units and two ABWR's. ::)

Or, you could put the spin on it that the EPR is 'proven & tested technology'...?
