My turn to share. First I'm not a nuclear engineer or even a rocket scientist. I got a GED in 1974 while stationed in Okinawa Japan.. But it seems to me you don't locate your elect back-up generators in the basement or bottom floor if you need to run them in an emergency, like to run your control room and cooling pumps to prevent a meltdown.....duh The hospital in New Orleans had the same problem during hurricane Katrina. Their emergency generators were useless because they were flooded in the basement. And if you have a flood, don't have an elevator that goes down to a basement that is flooded and drowns everyone inside. That happened during a flood in Houston. So a note to future engineers, locate your emergency generators on the roof or a floor near the roof. One more tip. Don't locate you nuclear power plants on or near major earthquake fault lines. Like Japan and Southern California have done. And build them on the east coast, so when one melts down the prevailing winds will blow the radiation out to sea or Europe.

Hindsight is wonderful isn't it? Just like the markets. :lol:

And what makes you think putting the generators on the roof won't cause some other problem? DUH.

I'm also not a nuclear scientist. But I'm willing to bet that structural engineer could have designed a water tower that would withstand and force of nature. Maybe even just some guy with a dump truck and a bulldozer. Pile up some dirt really high, call it a tower, and pre-pump some water into a vessel that sits on that tower. I've noticed that for some reason, when water is elevated above a pipe with a closed spigot, pressure builds up. No pumps are required during times when pumps are bound to fail. And I'll also bet that all of the diesel engines failed due to maintenance neglect (like not replacing stale fuel). They all ran for about an hour, then they all failed. Betcha, betcha, betcha.

You call it hindsight, I call it common sense. You put in a "emergency generator" for use in case of an emergency. I include flooding as an emergency.
Common sense also includes not building a nuclear plant on a faut line or "rim of fire"....duh
PS a generator on the roof should be sheltered from the elements.

splelchecker also makes a good point. Maint has to be done and the generators run at least twice a year to make sure they do what they're supposed to do.
I was in heavy equipment repair and Maint in the service and had yearly inspections on our equipment to make sure they were in working order.
Anyone of our generators were expected to run in short order when the Major stopped and wanted to see that one run. If it didn't, well there was helll to pay... :lol:

I am sure they have everything inspected annually and they were functional until a 8.9 scale earthquake hit, this is a nuclear reactor. But there seems to be not enough and well thought emergency measures. But then all of them could still fail after some 200 major earthquakes in a day. Each of the aftershocks were 5-6 scale, these are pretty big earthquakes, not just an aftershock...

Why don't they just use windmills in Japan?
There are few if any negatives with windfarms, at least according to Google news!

windfarms = very expensive energy

Better yet, underwater tsunamimills. Enough energy in your standard tsunami to charge batteries for 100 years.

[5:48 p.m. ET, 7:48 a.m. Tokyo] A meltdown may be under way at one of Fukushima Daiichi’s nuclear power reactors, an official with Japan’s nuclear and industrial safety agency told CNN Sunday.

A meltdown is a catastrophic failure of the reactor core, with a potential for widespread radiation release. However, Toshiro Bannai, director of the agency’s international affairs office, expressed confidence that efforts to control the crisis would prove successful.

Meanwhile, a second reactor at the same facility failed shortly after 5 a.m. Sunday, the Tokyo Electric Power Company said, according to TV Asahi. The power company said it was having difficulty cooling the reactor and may need to release radioactive steam in order to relieve pressure.
