Good info on Nuclear Reactor Start
That is good information about the lengthy time from proposal to building the reactor. You should also include the decommisioning costs as well as the decades it takes to break down the reactor infrastructures. The start up costs and the decommisioning costs pretty much wipes out the cost effectiveness of nuclear power. It is a shame that nuclear power never lived up to the hype "Too cheap to meter" that was part of the sales appeal of nuclear power.
Nuclear power will probably be in the mix for future energy needs. There are other types of reactors being considered, perhaps one of these would be cost efficient.
