Accident costs and alternatives
If this article is correct, than nuclear nations have these choices:
1) continue with existing plants, and
1a) hope the accident never happens.
1b) make saftey improvments, so that the probability of an accident goes down.
2) decomission the plants, and replace the nuclear power with
2a) fossil fuels, hydroelectric or whatever.
2b) safer next-gen nukes
1b) would be the most cost effective. Just taking Fukushima, relatively low cost improvements would have turned the problem into a trivial shut down.
for example, if a second diesel-electric generator had been built at 100 foot higher elevation, the reactors never would have lost cooling. Another idea, already used on newer reactors, is "passive cooling" . There is an artificial water resorvoir at an elvation slightly higher than the reactor. If the reactor loses it's normal cooling water, the resorvoir water flows through the reactor, propelled by gravity. This requires very few moving parts and makes very few assumptions about what has gone wrong.
It evaluated a range of disaster scenarios that might occur at the Dampierre plant. In the best-case scenario, costs came to €760 billion—more than a third of France’s GDP. At the other end of the spectrum: €5.8 trillion! Over three times France’s GDP. A devastating amount. So large that France could not possibly deal with it.
