That is because of the fuel types used. The Navy is using cheap fuel from the weapons program, which provides more than enough power and fuel for their needs. However the cities would likely use a Thorium reactor, which can easily be made to not produce weaponizeable (sp?) byproducts. I refuse to believe that France can handle itself with fission plants and we cannot. We must not allow irrational fears to drive policy and we must stop the use of fossil fuels to provide the majority of our power.<p>I say gimmie a few hundred fission plants, a new electrical grid, and electric cars &#38; trucks. Our greenhouse gas emissions will go way down and our geo-political strength will rise.
