Originally posted by sonhousegooglefudge is right about this. Windscale was not a nuclear power plant, it was a nuclear barbeque for making plutonium and the reason for the calamity was that they did not understand the physics of graphite in strong neutron fluxes well enough. At Chernobyl they did everything wrong, it's quite breath-taking, but the critical failure was to think they could save money by omitting a containment dome. Again at Fukishima there were problems with the design of the reactor. The safety rods were raised into the core rather than dropped. This is an obviously stupid move as it means you need power on to SCRAM the reactor. In British AGR's the safety rods are spring loaded and held out of the reactor by a magnet, so that in the event of a failure where power is lost the reactor is automatically SCRAMMED. Three Mile Island is the most worrying, but the design had some defects, most notably it was overcomplicated in the way engineering tended to be at that time.
Nuclear is certain, however the downsides are considerable. Look at Chernobyl or 3 mile Island. And you have to find a REALLY deep hole to deposit that 100,000 year half life leftovers. Fortunately the big accidents like Fukashima are few and far between but when they happen and they WILL happen somewhere sometime, they are really big disasters.
I see Fi ...[text shortened]... y day.
Now if the scientists and engineers will just get off their deadbeat asses and do it!
By way of comparison look up Chapelcross nuclear power station. They had a single channel fuel clad melt (partial meltdown) in 1967 and the reactor was up and running again in 1969.
The main worry with nuclear projects is that some idiots decide that it is more important to go for the cheapest option than the safest.
