So you are just going to totally ignore the fact that I stated that totally disproves your nuclear is safer than coal theory?
clclt.com...
Just two hours ago. Coal pollution. Hot off the press, grab it while you can.
Always happy to help :-)
That article in no way refutes what I stated. I already said coal is not a good power source. What I did say was coal does not have the potential to make entire contents uninhabitable. If you can give me a way that could happened with a coal fired (Or any other for that matter) I might have a change of mind but if your going to keep ignoring and side stepping the fact because it doesn't find into your nuclear power is great image that I have nothing els to say.

That poster has a track record of repeatedly ignoring facts, misquoting, not responding to questions, making issues about non issues and continuously trying to derail the topic of this thread - is a classic textbook case. I am totally with you about nuclear being worse than coal any day... the whole industry sucks and spends big bucks to snow job everyone and cover their incompetent and corrupt butts.

Unit 3 Spent Fuel Pool Temp Rise
In one month the temp has risen 13.5 Celsius (24.30 Fahrenheit).
Feb. 18, 2014 == 8.6 Celsius (47.48 Fahrenheit):
www.tepco.co.jp...
March 18, 2014 == 22.1 Celsius (71.78 Fahrenheit):
www.tepco.co.jp...
This is a rather significant temp rise for something that had been stable.
If anyone comes across an explanation...sure would appreciate you sharing.

edit on 18-3-2014 by Purplechive because: (no reason given)
From Moch:
Debris removal from reactor3 pool is in 4 months delay, Tepco reported to NRA (Nuclear Regulation Authority) this February.
Tepco is in the process to remove debris from around the spent fuel pool of reactor3.
However due to the extremely high level of radiation, it is being behind the schedule.
In the press conference of 3/17/2014, Tepco stated it may be because they suspended the removal when they found the workers severely contaminated possibly due to the emission from reactor3, where is over 500m away from the workers. They also stopped removing when they observed the “steam” coming up from the top of the building last summer. They also had to stop operation when the crane was significantly damaged, which the reason has not been identified yet.

And Unit 3 SFP temp suddenly drops a dramatic 3.3 degrees from 22.1 to 19.8....

I just found what I was exactly looking for in Netherlands
Back in 1912, Japan and Netherlands made a special treaty, which may change how Japanese live in 100 years from then. With that treaty, Japanese people can obtain visa with some advanced conditions. This is very based in their trading history for centuries. Netherlands was the only western country to trade with Japan from 17 th to 19 th centry until the last revolution. It became valid in 1960s after WW2 but it was forgotten in the dust of history almost completely. When this 100 years old international treaty was revived was only 4 years ago. I’m seeing a chance in this juridical “glitch”, so I came to Netherlands.
Then there is a link to a document that requires translation.
As the eyes of the world have been focused on the Unit 4’s removal of spent fuel, TEPCO released a report entitled, TEPCO’s Fukushima Nuclear Power Plant Roadmap, that contained some astounding information regarding Unit 3. Follow Fairewinds Energy’s Arnie Gundersen as he shows you the 35-ton refueling bridge that fell in the Unit 3 spent fuel pool during the Unit 3 detonation explosion. Do the math. The bottom line here is that TEPCO has just acknowledged that at least 50-tons of rubble has fallen on top of and into the spent fuel pool in Unit 3. What does this 50-ton pile of debris mean to the Unit 3 spent fuel pool and its cleanup?
TEPCO is behaving as though it is the victim of the largest industrial accident in the history of time rather than the perpetrator. Fairewinds Energy Education’s Arnie Gundersen analyzes new leaks at Fukushima Daiichi Unit 3 and discusses TEPCO’s negligence in not applying engineering rigor to its analysis of the leaks.
Treatment of radioactive water at Fukushima Daiichi nuclear power plant might be indefinitely suspended after malfunctions crippled the water purification process and recontaminated thousands of tons of partially purified water, Japanese media report. The failure in the system, known as the Advanced Liquid Processing System (ALPS), is the latest setback in Tokyo Electric Power Co.’s (TEPCO) uphill battle to stockpile radioactive water, which is ballooning at a rate of 400 tons per day. TEPCO said up to 900 tons of water, which had not been sufficiently cleaned in the ALPS equipment, flowed into a network of 21 tanks that were holding 15,000 tons of treated water. Not only have the 21 tanks been rendered unusable, but all 15,000 tons of previously cleaned water will now have to be retreated. While efforts are underway to measure the full extent of the contamination, TEPCO officials said the problem was not noticed prior to March 18 because no abnormalities were detected in water sampled on March 14, Japan’s Asashi Shimbun daily reports. “We never expected radioactive water to flow into the storage tanks,” Masayuki Ono, acting general manager of TEPCO’s Nuclear Power & Plant Siting Division, told the paper. “We should have been better prepared. We have no idea how long it will take to clean them if we decided to do so.”

Muon Detection of Nuclear Fuel
The technology exists to locate the molten cores and other places nuclear fuel scattered but TEPCO probably won't use it.
rt.com...
It is difficult to fathom that this should be TEPCO's decision to make. It should be imperative for the "decommissioning" plan to locate all the fuel ASAP.
However, it probably would cause too much "distress" and reveal many things that TEPCO does not want exposed.

Radiation high in Fukushima reservoirs
State and local government officials say they have detected radioactive substances exceeding government safety limits in soil at the bottom of agricultural dams and reservoirs in Fukushima Prefecture.
The agriculture ministry and the Fukushima prefectural government found 8,000 becquerels or more per kilogram of radioactive substances in 568 out of the 1,940 dams and reservoirs they inspected between last June and December.
108 were in the evacuation zones around the Fukushima Daiichi power plant, and 460 were further away.
Officials detected 370,000 becquerels per kilogram in the soil of a reservoir 58 kilometers away from the plant.
It is the highest reading so far recorded outside the evacuation zones, and more than 46 times the government limit of 8,000 becquerels for radioactive waste.
The state government is obliged to dispose of radioactive waste beyond this limit.
Prefectural officials say rain may have carried radioactive substances into the waters from surrounding forests.
Water from the reservoir with the highest reading outside the evacuation zones is being used for rice paddies nearby. But officials say they have not found radiation levels exceeding food safety limits in locally-produced rice, probably because radioactive substances in the soil barely dissolve in water.
The head of an association of residents says officials have told them they will not be exposed to radiation as long as there is water in the reservoir.
But he says they fear radioactive levels may surge if it dries up. He is urging the state government to address the problem as soon as possible.

Trouble stops fuel removal at Fukushima plant
The work to remove nuclear fuel from a storage pool at a reactor building in the crippled Fukushima Daiichi nuclear plant has been suspended due to a problematic crane.
Tokyo Electric Power Company said the issue occurred at around 9:30 AM on Wednesday, when workers started removing fuel units at the No.4 reactor building. The utility explained a large crane used to hoist a cask containing fuel units set off an alarm and stopped.
TEPCO added that the crane stopped before lifting the cask, and that no rise in radiation levels has been observed around the storage pool.
Workers are now trying to find out what caused the problem.
TEPCO began removing fuel units from the storage pool of the No.4 reactor in November of last year. The pool holds 1,533 units of fuel, of which 1,331 are highly radioactive spent fuel.
As of Tuesday, 550 fuel units had been removed and transferred to another storage pool.

Has not been that warm since Jan. 2, 2014:

Hopefully it is just the crane that is a problem...

The utility explained a large crane used to hoist a cask containing 22 spent fuel units from the storage pool suddenly halted before lifting the cask. Workers were attaching a hook to the crane's wire at that time.

Question for those of you who understand radiation - why can't they "freeze" all the rods with something like liquid nitrogen? Wouldn't that stop their emissions and all this need to radiate water trying to cool them?
Fuel removal resumes at Fukushima plant
The operator of the Fukushima Daiichi nuclear plant says it has resumed the process of removing spent fuel from one of the crippled reactors.
On Wednesday, an alarm suddenly activated and stopped a large crane, as workers were preparing to hoist a cask containing fuel assemblies from the pool at the No. 4 reactor building.
Tokyo Electric Power Company found that a worker had mistakenly operated the crane without releasing an auxiliary brake, causing it to become overloaded.
The problem was fixed, and the removal work resumed at noon on Sunday.
This was the first suspension of the operation since TEPCO started removing fuel units from the pool in the building last November. The utility is removing the fuel assemblies to decommission the Fukushima Daiichi nuclear plant.
1,533 fuel units were being stored in the pool at the time of the 2011 accident, and 983 were still there on Sunday.
