As I write this, another Japanese nuclear plant has suffered an explosion. News isn't in yet on how had it is. Apparently quite a few of their plants are in the middle of emergencies of varying severity.
My guess is that this will pretty much be the end of the nuclear power industry in most countries. People won't want to be near them. Insurance companies won't want to touch them. Politicians will certainly want to distance themselves from the industry.
Now there are some reactor designs that are a lot safer than the old existing plants. They are supposed to be inherently safe. The idea is that if anything goes wrong, the reaction automatically shuts off. I've no idea if the new designs are really as safe as they say they are. The old ones were supposed to be safe too. At one time, we were told the odds of a nuclear plant disaster were one in a million. Reality has proven otherwise.
What are our options now? Nuclear power provides a significant part of the world's energy. Get used to grid power becoming progressively unreliable. If you want power you can count on, make it yourself.
