The simple fact it is nuclear energy will doom it's implementation in the U.S. The average citizen doesn't understand the advances in reactor design and fundamental shifts a pebble bed reactor has with respect to efficientcy and safety. The envirowackos will use that ignorance against the better interests of this country and continue their massive no nuclear power for any reason at any time attitude. Even if the go ahead was given, it would be tied up in state and federal courts for decades before the first shovelful of dirt is turned in the construction.
One size fits all nuclear reactor please. Just like Southwest Airlines only flys 737. If there is a problem in one, look at this problem for all.
