Question for you nuc types ..
Just saw this in the news and would like to know the potential scenarios. May get better answers here than the sensationalism of the media.
Tokyo Electric Power Co. reporting they have lost control of pressure in No. 1 & 2 nuclear reactors with temps rising.
And another one:
Japan issues state of emergency at another nuclear power plant after cooling system failure

I called my brother in law and left a message with him. He is a senior reactor operator for a nuke plant, I will post when he calls me back.

The articles I just read went something like this. When the quake hit the reactors automatically shut down. The reactors you're talking about are boiling water generators. They rely on pumps to continue working in order to supply cooling water. The power grid that supplies the power to the 1st backup system for the pumps also went off line a short time after the reactors shut down. When that happened the on site diesel generators on the 2nd backup system kicked in but about 30 minutes later they failed as well, no reason given. There are now 4 rail cars on site that contain generators with more on the way. As soon as they can be wired into the nuclear plant the pumps can be brought back on line as long as nothing else has been damaged. The pressure in the reactor at the time of the article was reported at 1.5 times normal. A release of radioactive water into the ocean was permitted to keep the pressure from climbing.
If you compare this to Three Mile Island, the article reported that we are several steps away from that scenario.

I'm betting he and all the engineers will be working overtime re-examining every nut, bolt, specification and design on our systems for a while.

I have been to the plant he operates, there are so many redundancy factors it borders insanity in a good way. He showed me where the fission process takes place, I asked him what if everything failed. His reply was even without electric power they could manually lower some type of rod into the core and instantly stop the reaction process thus eliminating the need for continued cooling. This, as I remember what he said, I may be off a little bit.
I would like to think since GE made the plants that the redundancy factors would be comparable to what we have here?

Oh-Oh,.... here we go again.
Hope they can keep the plant under control, God know they have enough to deal with having thousands of folks with no homes and no food.

If I saw that on the TV i would say it's time to stick your head between your LEGGS and kiss you backside good bye or RUN!
I'm glad the plant i work at is coal fired, it was suppose to be built as a nuke back in the 70's but the public didn't like the idea too much so the company scrapped the plan.

Read that earlier today and was wondering. Now the latest news:
Authorities widen evacuation radius around stricken nuclear plant
The authorities say that there is no danger, but they are passing out iodine, widening the evacuation area around the plant to 12 miles and the Swiss rescue teams are been given iodine. Something does not add up, which is why I made the original post.

The building that housed the reactor blew because of the pressure, not good. The containment structure is still intact but now buried making it difficult to restore if not now impossible to restore cooling. Reactions do not just turn off, it takes time for them to stop. If the fuel rods become damaged while the reaction is still going on, it's game over.
