Whether it be the Generation III+ Pressurised Water Reactors (conventional) or the new Generation IV Molten Salt Reactors (currently a scheme got CAD$5m to do get started on one in Canada) that use Thorium fuel rather than uranium the point is this:

If we are serious about lessening needs on oil, coal and gas and where hydro is not available for baseload power production then nuclear becomes your next best option especially for the big 10 nations.

I saw a picture of a 250 hectare Solar Farm producting some 350MW of power. A Nuclear Plant that side with 4 times 2GW reactors can produce 8GW of power in the same amount of space with heat and steam byproducts that heavy industry could use if built near by.

That said technology has allowed conventional reactors and the MSRs to get right down to modular level and produce 225MW of power without a problem. As a comparison a Huntly Coal/gas boiler was 250MW while Otahuhu B now shut down produced 385MW.

The applications are there and nuclear where viable deserves a shot again if we are serious in dealing with emissions with power production.
