If you place a wager on whether a train will derail... is that considered off-track betting?

Also, as an addendum to Karl's post, the plant *did* survive the 9.0 quake. It was the combo of the quake and the tsunami that are causing the problems. Even after the plant automatically shut down, cooling water was still needed. The diesel back-up generators were taking care of that until the tsunami wiped them out. I realize that the quake and tsunami are related, but it still took a combo of truly epic events to cause the problems that are showing up.

Honestly, I think that the situation in Japan is an argument for the safety of Nuclear power. They got hit with the 5th largest earthquake on record, followed by a 30 foot tsunami. Their infrastructure is almost completely knocked out in the area and there's a lot of improvisation going on because of that. While there's likely a partial meltdown in progress in three of the reactors, thus far this still hasn't been a large scale event like Chernobyl and is very unlikely to get anywhere even close to that.

The media and nay-sayers are all going to be arguing against nuclear power because of this, but I think that credit needs to be given to the plant designers and to the folks improvising solutions for keeping this situation from being much worse than it is.
This was also an older-design plant; newer plants have even more safety precautions built-in, as a result of constant learning from the relatively few mini-disasters that have actually managed to happen. (And the big one...) Regardless, it has taken a lot to just damage the integrity of the plant in Japan, but it won't turn into any large-scale disaster.

Chris,

You are correct about the buildings and, from what I've read, it appears the reactor cool-down efforts are being affected by a lack of electricity. Maybe I should have worded my post a little differently but was a bit irked at the time.

Fuzzy,

Yep, newer plants are built to a higher-level of safety. Does that mean any plant built today is fail-safe? Hardly. But, we talking about a confluence of events that triggered the problems in Japan.

In America, why go nuclear over coal (or bio-mass, or alternative fuel sources)? We have plenty of coal, the cost of the coal plant is much cheaper, and a coal plant won't fail catastrophically and ruin the environment for hundreds of years (or longer).

The only "pro" I see to nuclear power is the claim that it is "clean energy", which is not true. The pollution for a nuclear power plant doesn't come out of the exhaust stacks like it does for coal, but it does comes out in other ways.

We still have no idea what to do with the spent fuel, so it's currently sitting in concrete bunkers at the facilities around the country. This material remains radioactive for well beyond any of our lifetimes, so the more we use, the more it's going to keep piling-up. Mind you, it's one of the cooling ponds for spent fuel rods that was over heating and causing fires in one of the Japanese power plants, not the reactor itself.

Aside from storage, there's the health risks and environmental issues of mining the Uranium.

Uranium Mining a Health Risk

Quote:
“All radiation is cumulative, every small amount of radiation you get adds to your susceptibility to cancer.”


Having watched two people in my life die of cancer in there mid thirties, I don't want to add to everyone's cancer risk when we've got gobs of coal.

Coal mining isn't great for the atmosphere, I'm sure, but neither is mining for Uranium...

Quote:
“With uranium mining you have to dig up hundreds of thousand of tones of ore and rock to discover the uranium. It is then crushed which produces more CO2.

“This is a very energy consuming process, to enrich the uranium."


SKODA Spent Nuclear Fuel Storage

Quote:
Once it has been removed from the reactor, spent fuel must be first safely stored in a spent fuel storage pool and then later on in a so-called interim storage facility. The first group of technology includes compact storage racks, which serve for short-term “wet” storage of spent nuclear fuel for a period of 5-7 years. The second group includes transport and storage casks, which serve for medium-term “dry” storage of spent fuel for a period of several tens of years.

“Several tens of years.” That’s some weird English. They either mean several hundred years or several thousand, but “several ten’s” sure doesn’t sound as bad... they must've used a creative marketing firm to come-up with this verbiage.

For those countries that haven't thought of an alternative to nuclear power, I guess they'll have to deal with the potential consequences. But in the U. S. of A., I think we can do better.

I'm just playing devil's advocate here because I'm not 100% against coal, but nuclear vs coal could probably be surmised as "Would you like your cancer now (but only in the event of a catastrophe) or later? Coal plants spew radiation, too, as well as other nasty stuff. Coal is light years cleaner than it used to be, but it still isn't *that* clean...

I'm still a fan of cheap, clean nuclear power. And yes, I'd really like to see Colorado get some nuclear power again. (Our lone nuclear plant, Ft. St. Vrain, was converted to gas turbine power before I moved out here. I took a tour of the plant a few months back. I even stood at the edge of the pit where the reactor core had been.)

MSNBC: Nuclear headache: What to do with 65,000 tons of spent fuel?

The Nuclear Regulatory Commission "apparently has no long-term plan other than hoping for a geologic repository," the unanimous ruling stated.


Reuters: Fukushima radiation seen in tuna off California
Quote:
Low levels of nuclear radiation from the tsunami-damaged Fukushima power plant have turned up in bluefin tuna off the California coast, suggesting that these fish carried radioactive compounds across the Pacific Ocean faster than wind or water can.


I'm just not seeing the case for nuclear power... all I can see is a recipe for a disaster, Fire Marshall Bill!
