Well, at least one Senator is:

OAK RIDGE, Tenn. (AP) — Tennessee Sen. Lamar Alexander called Wednesday for doubling the number of nuclear reactors nationwide, a potentially $700 billion proposal that calls for building 100 more over 20 years. “It is an aggressive goal, but with presidential leadership it could happen,” the third-ranking Senate Republican told an economic and technology conference at the Y-12 nuclear weapons plant in Oak Ridge.
“I am convinced it should happen because conservation and nuclear power are the only real alternatives we have today to produce enough low-cost, reliable, clean energy to clean the air, deal with climate change and keep good jobs from going overseas.”
