You Can STOP WORRYING ABOUT A RADIATION DISASTER IN JAPAN -- Here's Why
Business Insider ^ | March 13, 2011 | Dr. Josef Oehmen,

Posted on 03/14/2011 7:11:48 PM PDT by TennTuxedo

This was originally posted as a comment on Japan Death Toll Climbs Astronomically As Nuclear Crisis Spreads.

UPDATE: We have learned that this was written by Dr. Josef Oehmen, a research scientist at MIT. It was originally posted here.

I repeat, there was and will *not* be any significant release of radioactivity from the damaged Japanese reactors.

By "significant" I mean a level of radiation of more than what you would receive on - say - a long distance flight, or drinking a glass of beer that comes from certain areas with high levels of natural background radiation.

I have been reading every news release on the incident since the earthquake. There has not been one single report that was accurate and free of errors (and part of that problem is also a weakness in the Japanese crisis communication). By “not free of errors” I do not refer to tendentious anti-nuclear journalism – that is quite normal these days. By “not free of errors” I mean blatant errors regarding physics and natural law, as well as gross misinterpretation of facts, due to an obvious lack of fundamental and basic understanding of the way nuclear reactors are build and operated. I have read a 3 page report on CNN where every single paragraph contained an error.

We will have to cover some fundamentals, before we get into what is going on.

We are listening to the leftist drive-by media expounding the leftist driven hysteria. They want to make sure that we shut down every nuclear power plant in our country and abroad. The China Syndrome was fictional and will not occur. This is serious, but it is not something that should make us want to stop utilizing nuclear energy in our own nation

This guy’s not an expert. Nuclear energy isn’t his field (although it’s apparently his father’s).

We’ll just have to wait and see what the consequences are. Personally, I doubt there will be much effect that makes it across the Pacific to the United States. But this was and remains a serious situation.

Thanks for posting.

This has never made me think we should forego nuclear power, but I have been concerned from time to time about a localized health disaster. So this is good info.

Or, to put it another way: I think it's premature to say "you can stop worrying." I wouldn't worry much, but I think a statement that you can stop worrying entirely is entirely premature. Don't panic, but keep an eye on the situation, as it bears watching.

Again, I wouldn’t say it’s almost time to panic, but you’ve made a good point: we do seem to be in a worse situation than the outlook when this piece was written, and the momentum at the moment as far as I’ve seen is all in the negative direction.

At the same time, there are statements that a worst-case still won’t approach being Chernobyl.

I don’t believe there’s going to be anything on the level of Chernobyl but the Japanese are clearly becoming a little worried...or overly cautious: the Prime Minister just gave a live address consisting entirely of asking everyone within 20 KM of Fukushima Plant 1 to absolutely leave the area.

It is time for prudent folks to check their preparedness levels.

20 ft above sea level isn’t too far to go to hit groundwater if the containment is indeed breached. And if it is breached...there ain’t much to do about it other than prepare for the worst...

Here's a not very nice question...

Even if radio active fallout levels are low health wise, but still very detectable, what will that do to the California's wine and food industry?

Will people avoid buying California wines for example if vineyards end up with a light dusting of radioactive fallout? Even after being told the levels are of radioactivity are not dangerous?

I would guess that even the slightest hint of radioactive fallout on California's farm land could have MAJOR economic consequences for California.

If Plutonium ends up being released in large quantities, look out...

Reactor #3 has Plutonium for fuel. That’s the scary one.

The nuclear fuel heats water, the water boils and creates steam, the steam then drives turbines that create the electricity, and the steam is then cooled and condensed back to water, and the water send back to be heated by the nuclear fuel.

Now, what I know of nuclear reactor design says this is not true. Such a design exists to a degree.

I thought the water that was exposed to the core and superheated under some pressure formed the primary loop. The heat from this loop is transferred to a second loop via heat exchangers and it is this secondary loop containing non-contaminated water that is what forms the steam that drives the turbines and also cools the primary loop. Using steam from water that has been irradiated by the core to run turbines would also irradiate the turbines, no?

Am I wrong or have the Japanese screwed the pooch by using such an inherently dangerous design?

Then decide whether or not you should buy potassium iodide for your family, or if you should stop drinking milk until the Japan nuclear crisis subsides.

such an inherently dangerous design

Boiling Water Reactors were commercialized by General Electric and licensed to several other manufacturers (Toshiba and Hitachi for example). Feedwater is run through the core and the steam produced is used to turn the turbine. This layout is considerably easier to control than the PWR you tried to describe in your post. There are over 30 BWRs in the United States.

That’s the scary one

All light-water-reactor fuel forms Pu — it is an expected product of irradiating the non-fissile Uranium. Typical fuel creates Pu. MOX (a mix of uranium-dioxide and Pu-oxide) starts off with a non-zero amount of Pu. It is normal to burn Pu in a light-water-reactor.

Supposedly there’s a substantial amount of Plutonium in reactor #3, is that not true? They were using it to recycle nuclear weapons so the claim is.

Lets hope so. No more Nukes. We need to build natural gas and coal fired power plants. This is America lets use what we have. It never melts down and kills everyone.

Nor does nuclear power suffer natural gas explosions or coal mine disasters.

If your interest is solely accidental loss of life per KwH generated, nuclear is by far the safest means of generating electricity.

Don't go all hysterical on us...

Supposedly ...

Sorry, I thought I was being clear. Unit #3 was loaded with MOX fuel. The non-zero amount of Pu that MOX fuel starts with is either from retired weapons, or Pu extracted from spent fuel at the Japanese reprocessing facility. In any event, it is typical and normal for light-water-reactors to burn Pu during a fuel cycle. It is easier to fission Pu than U235 in the context of it takes less mass of Pu to create a critical (self-sustaining fission reaction) as compared to a self-sustaining Uranium process. In both cases, control rods with boron in them stop the fission reaction. The decay heat production rate is nearly the same with MOX fuel bundles and their Uranium cousins -- which is why they can be used in a commercial reactor without having to modify the reactor system.

You don’t have to die next week to get a lethal dose of radiation and die a sucky death in 10 - 15 years. They were still dying in 1980 from Hiroshima and Nagasaki.

So YOU say everything is going to be OK?! Why then this??

Next week you will be posting about how the TSA is crap. You ought to recognize the government "doing something" to make it look like they are "doing something" even though the action is ineffective -- to be polite. The safest thing to do during a radiation release is to stay indoors and minimize the air exchange with the outside. Contamination (dust) includes radioactive material -- fleeing the area in your car, etc. will expose you to that dust more than staying inside. Radioactive gas dissipates quickly. The most common contaminants will decay to undetectable level in a few hours/days. The yellow clothes you see nuke plant workers wear is to keep the dust off their bodies (and to let them see large patches of dust if they bump into something). Minimizing their time covered with dust or in a contaminated environment will minimize the dosage -- but dosage will be non-zero in that sorta work.
