Japanese N-Plant Explosion

Meanwhile, important work to restore power to the damaged reactors continues:
it may take a few more days before the vital cooling system is restored at the No. 2 reactor, whose containment vessel suffered damage in its pressure-suppression chamber, as some parts replacements are needed in the electrical system, according to the government's Nuclear and Industrial Safety Agency

Hi Chimpkin. You might want to look into the safety record of the Sellafield fast breeder reactor before you decide. It used to be called Windscale, but they had to change the name after it polluted the Irish Sea with radiation, and had numerous other "incidents" involving the release of radiaton. It's a notorious site here in the UK.

Well sure most predictions of the supply of U235 are that it is limited in that we have only a few hundred years of it. This would mean we will need fast breeder reactors making plutonium or molten salt reactors making U233 from Thorium, eventually, or at least have breeders making fissionables for LWR, of course the nominal life space for these reactors is 40-80 years so there is good chance reactors built today will make it to the end of there lives before we run out of U235. Reprocessing of course would do lot to add to that time, as even LWR can make make 80% of their fuel, and also handle most of the waste.
Here is a good article on cheap, safe, breeder design:

The decentralized system can pig-back on a centralized system, they aren't mutually elusive, the biggest problem is getting all the decentralized power sources, upgrading the grid is minor in comparison.
In the middle of the desert. Look renewable energy is abundant just about everywhere its simply a matter of taping into it. I think the government could do better by financing start-ups in renewable energy, and competitions for funds, like if say a solar company can make solar panels at X price in the state the government will automatically buy Y of them and mount them over government building parking lots.
Are you blind? It says "radiation exposed plant"
and goes on to say "It is very unusual for battle tanks to join disaster relief operations. But the ministry decided on the voluntary deployment because tanks have high radiation protection capabilities"
Now why would they need "high radiation protection"?
Reported: trolling, dishonest twisting of factual information etc.etc.
Have you not been following events? the whole site is contaminated. Idiot.

AH! we're in agreement then!
As far as what we can do to maximize current technology, what I'd like our government to do...if they can stop being so craniorectally inserted and actually institute progressive taxation...I was sort of hoping for a government-backed "rent-to-own" or pay-on-time program, wherein homeowners could install a PV system at what's an essentially at-cost rate...and if they fail to pay it off, it gets repossessed. Basically, let the homeowner pay the cost over time...the government ends up paying nothing in the end, the customer gets to sell electric to the grid, less new powerplant construction needs to happen, reliability is enhanced, everybody's smiling...
@ Ultra...I read the Sellafield Wiki...and I also found this Guardian article...
http://www.guardian.co.uk/environment/2009/apr/19/sellafield-nuclear-plant-cumbria-hazards
They were appallingly sloppy...almost as bad as Hanford.
Over at the Hanford site, they were digging around and found some misplaced plutonium in an unlined trench recently...:facepalm:
Maybe because the area is radioactive and not the debris its self!
Lets say I was to take a fallen tree out from the powerplant, how radioactive do you think that tree alone would be? What kind of radioactive material do you think contaminates the site? Take three mile island for example that place was so contaminated that half of the power plant is still manned and operational to this day
Actually, EF, although I don't like your trolling much or blatant ignorance, I would miss you if they banned you believe it or not. And yes, the tree would remain radioactive for a while at least. If you burned it, that would be dangerous 'cos the radiation in your tree would get in the air where you can breathe it in. And it would depend on the type of tree as well. An alpaca bamboo would be more dangerous than a pear tree. No, it wouldn't! I'm joking!
If you really want to know how contaminated the site is, look at the radiation reports from NISA, Japan's own Nuclear Watchdog. http://www.nisa.meti.go.jp/english/files/en20110320-4-2.pdf If you need help to interpret it, let me know, 'cos it's not simple. Sheets of data from recordings taken from all over the site, and the original values. It even tells you where in the site. OK? I told you, I only use the best sources, time and time again. The same sources the Japanese government use.
Dust on the site is more dangerous because it can be stirred up and inhaled, putting the radiation inside the body. Hence this warning:
REUTERSFLASH ReutersBreakingNews
Japan nuclear safety agency says it sees risk of radioactive dust being inhaled by workers at Fukushima but no sign that has happened yet
The industry won't collapse, of course it won't. But complacency, corruption and the "It couldn't happen to us" attitude are now dead. In the long run, this will improve nuclear safety, and if saftey is seen to be good, then confidence will return.

There was the hydrogen explosions, and there's been the presence of radioactive materials in the air.
Therefore the flood debris is contaminated-to what degree they will find out.
Likely will have to be assessed and the dirtiest of it buried onsite.
Only to rise next Halloween!!!!..:jason:
But yeah, that will keep a generation of nuclear engineers in line, the way the Macondo disaster will keep a generation of offshore oil drilling engineers in line...as my Smarter Half observed, it's kind of a generational thing, the complacency cycle.

Oh I can interpret it easily, the parameter is in the 10-20 uSv/hr range, that a tenth of a Chest X-ray an hour, that nothing, Ramsar got areas higher than that! At the reactor the highest areas are now down to 3-4 mSv/hr, even at the old 100 mSv/yr requirement radiation worker there could be in that for 25-33 hrs.
Funny, I hit you guys with so much evidence and explained arguments even chimpkin folded, and yet its all trolling and blatant ignorance to you, proof of rule #11 of the internet.
Oh yeah, lets see that happen
Aaah but how radioactive is it? For example a banana gives off 0.1 uSv or about .75 uSv per kg of bananas, now if the tree is giving off less radiation than that, I would assume its safe to eat, let alone be around.
I would think the smoke would probably be more harmful to you.
I disagree, these plants in japan were old 60's reactors and mind you probably kept in the best shape for reactors those archaic designs. So really this is keeping retired nuclear engineers in line, today's nuclear engineers are a generation separated and aren't going to learn any new less from this that haven't been accounted for in 3rd generation reactors.

2623.0-2946.0 uSv/H is what it actually reads at 500metres towards the main gate. Although not good, it's not risen. (Check if you were looking at todays readings, they go back to the 16th if I recall.)
It could be worse, but you have to remember - it's an illegal release of toxic radiation that shouldn't be there at all.
Going back to the CICA data, it seems the "Bolus" of reactor 2 was the cause of primary containment failiure. This is good in that it could simply be filled with concrete, sealing the damaged rods inside.

Nope.
It would only be illegal if it was done on purpose.
It's there because of an Earthquake and tsunami though.
Yeah, and the reason is that the workers are wearing Full Face Respirators with charcoal filter, TYVEK Suits which provide effective radiation dust protection while working.
Secondly the only radionuclide detected above the allowable limit is Iodine 131 (the rest are 1/35th or lower) which has a half life of 8 days, so the site will literally clean itself up in about 3 weeks.
Arthur
MP1-7 surround the parameter.
Illegal? "toxic radiation" exactly when does a radiation level become "toxic"?
Primary containment is only suspected to be damaged in Unit 2, and its already seal in concrete.
Depends on what criteria you're using, there's also different degrees of toxicity.
No shit, its a mess, and certainly dosages below 100 mSv are up in the air for how dangerous they are.
