Nuclear Power (spun off from Japan earthquake discussion)
They are evacuating the workers from the power plant due to a spike in rads.

There's talk in the US that because of what's going on in Japan that we should forget plans for building nuclear reactors. Unlike Japan, our entire country is not San Andreas fault, and we don't have quite the tsunami risk that Japan has. There are areas in the US that does have risks like these, but we don't have to build reactors there. Sure this is obvious, but probably not to politicians.

On the other hand, we have been using nuclear powered submarines for 50 odd years now and to the best of my knowledge no sailor has fallen sick so far. Food for thought here.

That's right, his name was Hymen Rickover. A brilliant scientist, engineer.

Obama's director of energy development has announced that the US should continue building nuclear plants despite what has happened in Japan. This seems very premature. We don't know yet how the nuclear disaster in Japan is going to play out. All the assurances about nuclear safety over the years are out the window. There has been controversy over the GE Mark 1 reactor since the 1970's. Is the containment vessel strong enough to withstand a coolant failure? Well, we will soon see.

Obviously, a reactor situated in Japan is going to be more succeptible to such things as tsunamis and earthquakes given that they are 1) on a relatively teeny weeny island compared to other land masses and that the effects of things are going to be much greater than say, Australia or Africa, 2) they are on a region of the sea known as The Ring of Fire( http://celebrating200years.noaa.gov/...f_fire_650.jpg )which is known for its violent and constant seismic activity and 3) that most of the fault lines near Japan are underwater and that tsunamis can occur in the event that the earthquake is powerful enough. A powerplant by the coast and an active fault line has alot more risks than one sitting above bedrock in the middle of nowhere. Does that mean that nuclear power is a bad investment? Not really. What can be taken away is that there needs to be a bit more planning in where reactors are put and that there should be a certain planned obsolescence where old technologies are either updated or replaced altogether. Just because someone gets into a car accident does not mean cars are unsafe and should never be used. There just needs to be a healthy amount of risk anticipation and mitigation when using such technology is all.

There are still Mark 1 reactors in this country. Their containment vessel is much less robust that subsequent GE plants. That said, there has been no failure of any Mark 1 containment vessels. However, we still don't know if one has failed in Japan. The Japanese were well aware of the risk of placing nuclear plants on the East coast of the country and they planned carefully. They assumed a potential tsunami created by a 7.2 earthquake to be the maximum. They built a 25 foot breakwater wall around the plant. They installed backup diesel generators to maintain water levels in the reactor in case of a failure. Well, instead of a 7.2, they had a 9.0! A 9.0 is many times more powerful than a 7.2 and the tsunami created, rushed over the breakwater as if it wasn't there. Severe damage was done to the plant including the diesel backup generators. Mother nature seems to have a habit of doing in man's the best laid plans.

1-The mark 1 was "popular" because it was cheaper to build. 2- It is cheaper to build next to the ocean for cooling and accessibility. Cost vs safety levels is where decisions are made. A traditional steam plant has minimal public risk. A nuclear plant has extreme public risk. Are nuclear plants worth the risk? If nuclear plants are designed and built to be virtually risk free to the public, the cost would be prohibitive. They would probably need to be buried deep in solid rock mountains. So we build nuclear plants and take a risk with public lives.

This is the very reason not to build them, The Unknown. It's like mother nature is getting the blame again. I live within a 100 miles of Diablo Cyn. and I still say no one has the right to risk my ass to make money, and this is what the bottom line is.

In the US there are PLENTY of places to build nuclear reactors that are not on a fault, not where tsunamis can happen, not where hurricans are a danger, not where flooding can happen, not where there's a lot of tornados, etc. Humanity didn't get to where it is by having a defeatist attitude. When problems arise we can figure out how to design around them. I guess in Japan's case they were running out of options to power their country and unfortunately accepted known risks.

Certainly the combination of earthquake and tsunami that devastated the nuclear plants in Japan was a rare and unusual event. The destruction of power lines to the plant and damage to the plumbing, pumps and backup generators has prevented rapid stabilization of the nuclear facilities. Could this happen here? I think it is very doubtful such a catastrophic event could happen here. That's not to say that our nuclear facilities are one hundred percent reliable, however. We have 23 GE Mark 1 nuclear reactors similar to the ones in Japan. As long as the coolant water system is functioning, they seem to be fine. Newer plants rely on convection cooling rather than pumps. Pehaps, it is time to retire the Mark 1s. Oh wait! we have an oil problem, don't we!

But yes, we have an oil problem, which is not helped by the moratoreum on drilling in the gulf. BO wants to (or has he already) tax coal into oblivion. He continues to restrict drilling in the gulf. If politicians succeed in shutting down nuclear reactors here then what then? Are we supposed to power our country with windmills?
