*** Fukushima *** and other nuclear-----updates and links

hey windy?.. do you have the source link?

cheers xo... that is a very bleak map... but i need to be sure on the source.. look at the spread over the equatorial climactic central divide!

damn.. i just moved our lot to QLD from WA......

i am curious about their timestamping and inferences....
duley noted are their lack of "data", either empirical or assumed or indeed computer generated at 'particular' borders....

i thought these nuke dudes were very clever scientists.....

It is afir from the Tsunami it self,
not the Contamination!

The NRX Incident, 60 Years ago (12 Dec. 1952)
On December 12, 1952, a partial meltdown of the NRX reactor core at Chalk River, Ontario, occurred. The causes of the accident provide insight for more recent events. The environmental effects indicate what might be expected from reactors in emergency conditions. Because this was the first serious reactor accident in the world, statistical information about the workers gives the best data about long-term health hazards associated with such events.

THE ACCIDENT
On the day of the accident, NRX was set at low power. The investigations being carried out dealt mainly with coolant flow through the calandria tubes. A number of the tubes were disconnected from the high-pressure ordinary water coolant system; one was being cooled only with air, while the others were connected by hoses to a temporary cooling system. The depth of heavy water in the calandria was to be raised from 2.6 m to 2.77 m.

There were a series of valves in the basement beneath the reactor which controlled the control rod pneumatic system. Some of them had actually had their handles removed to prevent them being opened. Nevertheless, an operator opened three or four of them by mistake. As a result, air pressure from above was reduced, and air pressure from below caused three or four control rods to rise out of the reactor. This was the first step in the accident.

The movement of the control rods was indicated by red lights coming on in the control room. The supervisor telephoned the operator in the basement, telling him to stop opening the valves. The supervisor then left the control room, went to the basement, closed the valves himself and checked the air pressure.

The control rods should have fallen back into the calandria, and the supervisor assumed they had. They moved downward enough to clear the red lights in the control room, but--for mechanical reasons not understood--not completely into the reactor.

The supervisor called the control room from the basement, wanting to tell his assistant to press the two pushbuttons which would seal the control rods into the pneumatic system and then activate the air pressure to push the control rods down. However, he made a slip in giving the numbers of the pushbuttons, giving instead the number of the pushbutton which controls the pneumatic system and the number of the pushbutton which withdraws the safeguard bank. The assistant could see that the red lights referring to the other control rods had cleared, meaning that there should have been enough control rods down in the calandria to keep the reactor shut down. The assistant therefore thought it was perfectly normal for his supervisor to ask him to withdraw the safeguard bank and he did so, putting down the telephone so that he could reach over and depress the pushbutton to activate the pneumatic system. The supervisor in the basement immediately realized his mistake and yelled into the telephone to correct himself. But the assistant did not hear, since he did not have the telephone to his ear. The time was 15h07.

With a number of control rods only partially in place, the raising of the safeguard bank caused the power output of the reactor to double every 2 sec, according to later investigation. The people in the control room soon noticed the power rising dramatically, and the assistant activated the release mechanism for the safeguard bank after about 20 sec. The reactor power was about 0.1 MW at that moment.

Because the pneumatic seals had not been activated, the pneumatic system could not push the four control rods of the safeguard bank into the calandria quickly. Even gravity alone should have drawn them downward, but three of them did not fall, and the fourth fell much more slowly than it should have. It would be about 90 seconds before that control rod was fully in place. So the reactor continued to increase power; it would have levelled off at about 20 MW if the reactor's cooling system had not been altered for the test.

However, after only 10 sec the power output was about 17 MW, and the ordinary water in those calandria tubes which were being cooled by the temporary system began to boil, severely reducing the capability of the cooling system. The power output began to increase more sharply. This was noticed in the control room and, some 14 sec later, someone else in the control room threw the switch to begin dumping the heavy water moderator out the bottom of the calandria. Reactor power increased for about 5 sec more, and peaked at 80MW, but once the moderator level was dropping, the reactions were quenched and the reactor could not continue to run away. Some 25 sec later, the power output was zero. The total time that the power level was above 1MW was less than 62 sec.

Nevertheless, the situation got worse. A gauge in the control room indicated that the pressure of helium gas above the heavy water inside the calandria was dropping sharply. The assistant was concerned that the connection to the gas holder might be blocked and, if so, there was a danger that the calandria might implode as the heavy water was removed. The assistant stopped the dump, but resumed a few seconds later when he noticed that the gas holder was still emptying. The heavy water level in the calandria was eventually stabilized at 1.34 m depth.

Inside the reactor, the sheathing around some of the fuel rods and even some of the calandria tubes had burst. Not only helium, but hydrogen and other gases formed by heat and chemical reactions in the fuel rods were present inside and escaping from the calandria. The dome of the gas holder dropped to its lowest point and jammed there. With no additional source of helium to fill the calandria, air rushed in. At 15h11, the dome of the gas holder suddenly jumped to its highest point, indicating that a hydrogen-oxygen explosion took place inside the calandria. The calandria did not suffer complete structural failure, and more than 150 of the calandria tubes did not rupture. This explosion marks the end of the accident.

To cool the reactor, the ordinary water cooling system was not shut down. All of this water was radioactive, and it leaked out onto the floor of the reactor building. By 18h, the floor was awash. Within a few days, the water was 1m deep, and had spilled into the gas holder's room and the two rooms containing the heavy water storage tanks. The system was maintained so that the leakage rate continued to be about 4 litres per second. A 106 litre tank of clean water was emptied to the Ottawa River and then the contaminated water was pumped into the tank. In total, some 4.5 x 106 litres of water were involved. Decontamination and clean-up required many months. The calandria was removed, buried and replaced by a new one. NRX was back in service within two years.

TEPCO shares soar further

TOKYO — Shares in Tokyo Electric Power (TEPCO) soared for a second straight day Tuesday after Shinzo Abe’s election win fuelled speculation that plans to ditch atomic power in disaster-scarred Japan will be shelved.

The utility giant’s stock ended up 17.32% at 237 yen after spiking nearly 28% in morning trade on the Tokyo Stock Exchange.

The rally came after TEPCO—whose Fukushima Daiichi plant was at the centre of last year’s tsunami-sparked atomic crisis—rocketed 32.89% to 202 yen on Monday.

However, the firm’s stock is still a fraction of its pre-disaster price above 2,100 yen.

City budget approved for lawsuit to stop nuclear plant construction

The municipal assembly of Hakodate in Hokkaido on Tuesday approved funds to file a lawsuit to stop construction of a nuclear power plant in neighboring Aomori Prefecture.

The local government on Japan's northernmost main island is considering resorting to legal action if construction by Electric Power Development Co. of the plant in Oma across the Tsugaru Straits from Hakodate continues.

Backup issues put Swedish units out of action

Concerns over diesel backup generators have forced two of OKG’s three units at Oskarshamn off line as Sweden prepares for the coldest months of the year. Oskarshamn 1 is likely to remain off line until mid-January.

Oskarshamn 1 had only recently restarted after over a year out of service, following problems with vibrations in the turbine system and the detection of damage to reactor vessel internals during the plant’s regular maintenance outage.

Meanwhile, Oskarshamn 2 is being kept off line for work on its backup generators after Swedish regulators ordered an immediate shutdown of the unit. The Swedish Radiation Safety Authority issued its instruction on 6 December on the grounds that OKG had not been able to demonstrate that “equipment essential for ensuring safe operation” fully met requirements for operability and reliability.

NORWAY BEGINS FOUR YEAR TEST OF THORIUM NUCLEAR REACTOR

A Norwegian company is breaking with convention and switching to an alternative energy it hopes will be safer, cleaner and more efficient. But this isn’t about ditching fossil fuels, but rather about making the switch from uranium to thorium. Oslo based Thor Energy is pairing up with the Norwegian government and US-based (but Japanese/Toshiba owned) Westinghouse to begin a four year test that they hope will dispel doubts and make thorium the rule rather than the exception. The thorium will run at a government reactor in Halden.

Keep off Bay beach warning repeated
[link to www.dunfermlinepress.com]

[snip]

The radioactive particles on the beach are believed to have come from dismantled aircraft from the former Donibristle RAF base.

The Disposal of Radioactive Waste report written in 1958 warned of "undesirably high levels of radiation" at sites where aircraft were scrapped.

The Dalgety Bay contamination is widely believed to have come from paint used on aircraft instruments which were disposed of at the former RAF airfield.

Coastal erosion continues to result in contaminated particles being found on the shore.

This article implies that material was dumped.

North Korea satellite 'tumbling in space'
[link to www.bbc.co.uk]

[snip]

The launch last week was North Korea's first successful use of a three-stage rocket to put a satellite into orbit - a similar launch in April failed just after take-off.

The BBC's diplomatic correspondent Jonathan Marcus says it appears to mark another step towards North Korea's ability to field an intercontinental range ballistic missile.

Such a missile could be used to carry nuclear warheads.

Fukushima plant situation 'volatile,' a year after cold shutdown declared
[link to ajw.asahi.com]

[snip]

Workers are nowhere close to determining the state of melted fuel at the Fukushima No. 1 nuclear plant, a year after the government declared the damaged reactors were in a “cold shutdown” state.

Endoscope surveys of the containment vessels at the No. 2 reactor in January and the No. 1 reactor in October found radiation levels high enough to kill a human within one hour. Specifically, up to 73 sieverts per hour was detected inside the No. 2 reactor and 11 sieverts per hour inside the No. 1 reactor.

Storage tanks on the plant's premises have a total capacity of 257,000 tons. As of Dec. 11, the tanks contained 237,000 tons of radioactive water.

Groundwater flowing into the reactor buildings is exacerbating the radioactive water problem. TEPCO said it will dig wells west of the reactor buildings to pump up the groundwater and reduce the inflow, but little is known about groundwater flow variations, sources said.

"Despite the (officially declared) cold shutdowns of the reactors, the cooling functions have been maintained there with no knowledge of where the melted fuel lies and in what state," Tanabe said. "There is a risk of unforeseen circumstances arising if another major earthquake hits."

Annual Assessment of the U.S. Nuclear Weapons Stockpile

Key Point: The Annual Assessment process of the U.S. Nuclear Weapons Stockpile is the authoritative method for the Department of Defense (DoD) and the Department of Energy’s National Nuclear Security Administration (DOE NNSA) to evaluate the safety, reliability, performance and military effectiveness of the nuclear weapons stockpile, and it is a principal factor in our ability to maintain a credible nuclear deterrent without nuclear explosive testing.

Many People, incl. me cant believe that
this Election was won by Mr. Abe in this
high and clear amount of Votes!

Okay, i can understand many things,
even that the People are tired of this
darkness in Tokyo/ East-Japam
(we still use ca. 30%
less than in the Winter pre-Fukushima)
but that this came so clear is a surprise
for everyone!

On the other side this; People like Mr. Abe
are Patriots and every Patriot love his own Motherland,
Contamination will destroy this Mother ergo
Nuclear Power is unpatriotic!

I hope they will understand this soon.

Stupid History, they could get soooo much Gas
from Russia but no, tooooo many bad Memories
and tooooo much Fear to "need" them.

It seems to go against reason..
Obviously, there are factors that are not well understood.

interesting.....

retirement good....

but alot of bad....

the article brings up the follwing points:

1. what if they can't bankroll the maintenance?... storage?.. upkeep?.... evil times ahead.. we have nowhere to put it.. may as well call an ELE in the next 40-100 years if they can't find a solution... they can't keep boiling forever...

i forwarned of this along time ago, but it yielded little public or academic interest....

a nuke plant is as old as what we consider to be an antique vehicle... without new parts, how fast would the jalope fall apart?... see many stock standard sherman tanks in mint condition?... stuff rust, corodes, warps...

ever think they can get near some of the internals?....

the doom bell has tolled, well and truly..... as fukushima continues to spew it's poison 24/7... a kind of two evils.. it took a presumed ELE eventually, to alert the world to covert world of nuclear science and fact......

Well... yeah... a lot of bad. The public will end up having to pay for the decommissioning when those fuckers go bankrupt.
A cool billion US to do one plant and that will increase exponentially..

So, you think the corium jumped back up into the vessel...?
Mkay.

Never left, not in Nr. 1 (not soooo sure, maybe 5% Doubt),
not in Nr. 2 (No Doubt) and not in Nr. 3! (No Doubt)

Where else do you think the Heat is coming from?
How else they get the cooling Water back?
How there can be Pressure when there is a Hole?

Let's figure it out..

Just kidding..
