  • Probably pretty well. Solid concrete shells are pretty good for that.
    No, I did not steal that from somebody on Something Awful.

      Yep. Containment should be able to take a direct 747 hit.

        I would say IF they are allowed to restart.

          A valid concern.

            They're so big and massive (made up of concrete and steel) that I doubt even a huge tornado could wreck them. Now, the tornado would likely damage power lines or even close to surface water lines (or more likely their electrical pumping stations) and that could cause cooling problems. I believe the Japanese plant had batteries to run the cooling systems even if the power went out (the reactor itself was shut down just after the earthquake) but that the reactor remains hot for several weeks after shut down and there was some problem with either the batteries not being enough to power the back up cooling system or the back up system itself had some sort of damage due to the earthquake. It must have been some massive damage because supposedly everything is triple redundant with these power plants.

              Especially since US and Japanese reactors have secondary containment domes unlike the old Soviet designs like the Chernobyl plant.

                No.

                No batteries for power to pumps. Diesel generaors with 30 days of diesel inventory. Requirements in states at least are 30 day supplies in order to allow safe shut down where safe s hutdown means removal of all residual heat and no release of radioactivity to the environemnt beyond permitted levels.

                Please do not confuse the issue. Batteries are not an option for the sizable power required for these pumps.

                  Not particularly. Those things are what, four to five feet of solid steel-reinforced concrete?

                  • OK, I guess I was confused. They have diesel powered generators instead of batteries.

                    • Uninformed question: Whenever there's an article on slashdot (yeah, I know) that involves nuclear power there's always a few dozen zealots saying that pebble bed reactors are perfectly safe and physically can't cause major problems. If this had been a pebble bed instead of a light water boiler, what would have happened?

                        Some of the old ones are probably going to be closed, but the rest wil probably be restarted. Though, I think that there will be a migration plan moving things to the west coast of japan.
                        With or without religion, you would have good people doing good things and evil people doing evil things. But for good people to do evil things, that takes religion.

                          Uhmn, just reading the wiki on this make me scared

                          • Slashdot just makes me angry. The articles there are......awful.

                              Don't know much about these style reactors. No commercial scale ones exist as far as I know. Until that happens and they have a body of operating experience I reserve judgement.

                              • Ogie, is it true that nuclear reactors have immense security precautions in everything from computer networks to going to the bathroom? Can you tell us what it is like working at one? (I gather you work at a nuclear plant)
