Senator Dianne Feinstein, seen here giving a self-facepalm has suggested the federal government perform a massive expensive reevaluation of U.S. plant quake risks. An almost identical comprehensive study was performed three years ago and concluded the nation was safe.  (Source: NewsReal)
Apparently they missed the first study's conclusions

Yesterday we pointed out that a newly released study by the Nuclear Regulatory Commission (NRC) concluded that nuclear power plants in the U.S. were well within acceptable levels of risk and should be deemed safe.  Unfortunately a report by MSNBC largely missed that conclusion.

And apparently they weren't the only ones.  The report has apparently touched off a bout of nuclear hysteria in Congress.  

Sen. Barbara Boxer (D-Calif.), chairman of the Senate's Environment and Public Works Committee, and Sen. Tom Carper (D-Del.), chairman of the Senate Clean Air and Nuclear Safety Subcommittee demanded that the NRC perform a costly extensive study to determine if the plants are safe.

They write, "We call on the NRC to conduct a comprehensive investigation of all nuclear facilities in the United States to assess their capacity to withstand catastrophic natural or man-made disasters including scenarios that may be considered remote like the recent events in Japan."

"These domestic nuclear reactors must be fully evaluated to ensure that they are as safe and resilient as possible, that worst case scenarios are examined and addressed, and that personnel training and equipment for emergency responses are in place and up-to-date. Special and immediate attention should be given to those U.S. nuclear reactors that share similar characteristics as the failing reactors in Japan, including similar designs or located near a coastline or seismic fault line."

Apparently they missed the fact that the NRC did almost exactly that 3 years ago in 2008 (the study we referenced in yesterday's piece).  And their conclusion?  We're safe.

The only remaining question is whether Japan's nuclear plant situation would actually change any of the conclusions in the paper.  The answer, for most plants, is probably not.  

Only plants near flood-prone regions, or coastal regions in danger of tsunami strikes, might have additional risks due to the possibility of knocked out backup generators.

While the Senators do suggest an inquiry of such locations, they also ask for much more -- an investigation of "all nuclear facilities" with little factual justification provided.

The proposal also calls for other possibly expensive and unusual suggestions, such as requesting:

How comprehensive is the radiation monitoring system in Japan? Would the U.S. take a similar monitoring approach if a serious accident were to occur here? What increased risk is associated with exposure to mixed oxide fuel?

It also contains alarming language, such as:

Has the NRC modeled what could happen if the U.S. had multiple nuclear accidents simultaneously? If so, how would the NRC respond to such a disaster?

At a time when our nation's federal and state governments are facing huge budget deficits, this should be an excellent test of exactly how frenzied the public is about nuclear power in the U.S.  Will they stand by and support this expensive study, which is essentially a repeat of one just done a couple years ago?

One person is awfully satisfied with the news -- the original MSNBC report's author, Bill Dedman.  He brags of how he motivated the government to push the expensive study repeat, writing, "Three U.S. senators on Thursday called on the Nuclear Regulatory Commission to answer for the safety and emergency preparedness at all nuclear facilities in the United States."

"As reported on Wednesday, the NRC has raised its earthquake damage estimates for the nation's 104 commercial nuclear power plants, particularly for those in the eastern and central states, where seismologists say the earthquake risk is higher than previously thought. The estimates by the NRC were provided to, which ranked the reactors by risk."

cut/paste from the Wikipedia article on Sievert (the SI unit of radiation exposure).

Living near a nuclear power station: 0.0001–0.01 mSv/year[5][1]
Living near a coal power station: 0.0003 mSv/year[1]
Cosmic radiation (from sky) at sea level: 0.24 mSv/year[5]
Terrestrial radiation (from ground): 0.28 mSv/year[5]
Natural radiation in the human body: 0.40 mSv/year[5]
Radiation produced by the granite of the United States Capitol building: 0.85 mSv/year[7]
Average individual background radiation dose: 2 mSv/year; 1.5 mSv/year for Australians, 3.0 for Americans[1][8]
New York-Tokyo flights for airline crew: 9 mSv/year[8]
Atmospheric sources (mostly radon): 2 mSv/year[9][5]
Total average radiation dose for Americans: 6.2 mSv/year[10]
Smoking 1.5 packs/day: 13-60 mSv/year[7][11]
Current average limit for nuclear workers: 20 mSv/year[8]
Background radiation in parts of Iran, India and Europe: 50 mSv/year[8]
Lowest clearly carcinogenic level: 100 mSv/year[8]
Elevated limit for workers during Fukushima emergency: 250 mSv/year[12]

The problem that the two senators from California have is that nuclear power is not only cost effective, but (unlike everything else) actually CLEAN (if done right, as in not with bad designs and reactors old enough to be president). Coal and oil give us smog and crap which has to be scrubbed at great expense, all the renewable energy sources also harm the environment (wind turbines slaughter birds and their lubricants pollute the ground, solar causes problems with localized heating and takes large amounts of land) in addition to being stupidly expensive. Ms. Palin is 100% correct, the Obama energy platform is to increase prices. High energy and food prices mean more dependence on government assistance, a decrease in actual wages, and the spread of the Democrat's most faithful voters, those whom depend on government assistance to live.

America has the ability to end the need for fossil fuel plants (which put crap in the air), stupid expensive alternative power, and severely cut our need for fossil fuels with nuclear power. It is possible (with the government doing the heavy lifting) to replace ALL power generation in America with thorium-based molten salt reactors at no cost to the operators, except retraining. This would, of course, use a standardized design, which reduces both plant and training costs as parts and training are universal.

You know, Nuclear Waste is generated all during the plant's lifetime right?

Currently, we just let the waste -sit there-, even though with reprocessing significant fractions could be reused...

By significant fractions he means around 80%.

What's more, refined fuels like this that have been depleted can actually be used in other reactor designs with minimal reprocessing.

Designs like the CANDU are actually shockingly efficient in their use of fuel and can fission U-235, PU-239 and PU-241. In most other reactor designs Plutonium atoms are a waste product from the capture of neutrons by the non-fissile U-238.

The other interesting aspect is that they are dramatically less likely to produce PU-240 (a self heating, spontaneously fissioning element) through the capture of neutrons by PU-239. What's more, any PU-241 produced via neutron capture by these smaller quantities of PU-240 will also be fissioned.

This means that spent fuel rods from a CANDU reactor contain dramatically less plutonium in them than other designs.I most cases, the spent fuel is closer to depleted uranium than to raw uranium.

Actually, some people have been pointing it more at the 95% mark with newer methods to reprocess uranium.

People also forget to mention, the 5% unrecoverable is... DUN DUN DUN:

Converted to the energy that makes this whole thing work! *SHOCK*.
