I have been wanting to bring Chuba.co Hamoara up all day they have 2 toshi reactors one split/burst pipes in '02 they decided to replace parts on the other to be safe. In '06 government decided to tighten quake rules for plants and asked them all to do proper geological seismology surveys etc (no evidence yet that tepco ever fully complied. hamoara did them during this time the '07 quake struck causing the accident at tepco's K...plant . Anyways after quake although report gave them all clear to srart up again (they had automatically shut in quake) the locals went to court to get decision to let them start 1+2 up overturned -the people lost the courts said restart but chuba never restarted them they said the work neded to make them safe was too much and as they had #7 under construction 1 + 2 would be decommissioned . www.chuden.co.jp
I find that strange they decommission theirs as tepco load theirs with mox and why did they feel that to just comply with government standards wasnt enough
by elainekirk 4/23/2011 1:52:24 AM

@elainekirk the situation around #3 combined with the known design flaws, being past life span, an experimental shroud replacment AND MOX fuel. Sorry but that i just criminal negligence.

Nuclear experts say Fukushima accident was avoidable

A group of 16 nuclear safety experts has issued proposals for preventing a recurrence of the Fukushima No. 1 nuclear power plant accident, saying that "relatively inexpensive improvements, detectable by more extensive analysis beforehand" may have prevented it altogether.

The joint statement by experts representing 11 countries, including the United States, Russia, India and Sweden, was presented to the International Atomic Energy Agency.

In the statement titled "Never Again: An Essential Goal for Nuclear Safety," experts also recommended that future nuclear power plants be located away from "areas of extreme natural and manmade hazards." The translation of the statement was posted on April 19 by the Japan Atomic Industrial Forum on its website with its original English version. www.asahi.com

Warnings of nuclear disaster not heeded, claims former governor...
www.independent.co.uk
And the lesson? Replacing Tepco's management won't solve anything, he says, because the logic of Japan's energy policies is that nuclear power generation is absolutely necessary. "So nuclear power must be seen as absolutely safe." Ordinary people must "take democracy into their own hands", he added. "If they do not, in 10 years time we will see another disaster. It's almost as though we are in a fascist country where information is hidden from the public. This is time for Japan to wake up and see what the situation is."

online.wsj.com TOKYO—Japan's government said it will largely take over speaking for embattled Tokyo Electric Power Co., after six weeks of nuclear crisis at the company's Fukushima Daiichi power complex have often generated conflicting reports from the government and Tepco.

Japan's Ministry of Economy, Trade and Industry, which oversees the country's top nuclear regulator, said Friday said it will run Tepco's main daily plant-status briefing, held each evening, though the company will conduct some others on its own.

TEPCO to cautiously inject water in No.4 fuel pool
Tokyo Electric Power Company has decided to be more cautious about the volume of cooling water injected into the spent fuel pool of one of its reactors. This is due to fear that the reactor building might be further damaged by the weight of the water itself.

The company has been injecting water daily into the spent fuel pools of the reactors to prevent fuel rods from being exposed and further damaged.

At the Number 4 reactor's pool, the water temperature was about 91 degrees Celsius on Friday, more than 50 degrees higher than the normal level, and TEPCO was forced to inject 200 tons of water. Substantial amounts of water will have to be injected daily.

Citing damage to the walls of the building supporting the pool during last month's hydrogen explosion, the power company says excessive water injection could further weaken the structure of the building.

From Saturday, the utility started assessing more carefully the appropriate amount of water to be poured into the pool, using a device to monitor temperature and the level of cooling water in the pool.

1,535 spent fuel rods are stored in the pool of the Number 4 reactor's building, the largest amount at the site.

Cattle in the restricted zone
Tens of thousands of farm animals have been abandoned in the evacuation zone surrounding the Fukushima Dai-ichi nuclear power plant. Many of them reportedly have already died.

Fukushima Prefecture authorities say there were about three-hundred livestock farms with three-thousand cows, 30-thousand pigs, and 600-thousand chickens.

A veterinarian who inspected barns and chicken coops on Friday last week, before the area was designated off limits, says almost all the chickens had died.

He says about 70 percent of the pigs at barns with automatic feeders were alive. But most pigs in other barns were dead.

Most of the beef cattle had been let out to graze, and were still alive. But about 60 percent of the dairy cows in barns had died.

Farmers are asking government to allow them to take the animals out of the area, or permit them to take care of their livestock.

Some farmers are requesting that they be allowed to euthanize the remaining animals.

The agriculture ministry says, however, it will be difficult to allow people to enter the restricted area to euthanize or feed the animals.

Reactor 1 water level concerns

The Japanese government has expressed concern about the structural strength of the Fukushima Dai-ichi nuclear power plant's Number 1 reactor. It says the ongoing water injections may be making the vessel less earthquake resistant.

Tokyo Electric Power Company, or TEPCO, is planning to fill part of the containment vessel with water to cool the reactor.

TEPCO wants the water level to reach the top of the fuel rods in reactors one and three by mid July, so it can cool them under more stable conditions.

At the Number 1 reactor, where fuel rods are believed to be the most seriously damaged, six tons of water are being injected every hour.

TEPCO believes the water is vaporizing, then condensing in the containment vessel.

The water level is now estimated to be about half way up the bulb of the dry well.

TEPCO says the water accumulation will not compromise the structure. But the Nuclear and Industrial Safety Agency says large amounts of water can make the building less earthquake-proof.

The agency says it needs to check whether the suppression pool pipes can withstand higher levels of pressure from the extra water.

Seems like they are taking the NCR leaked assessment as a playbook, considering these last two decisions on the reactors.

Yoimuri Online (translated through Chrome/google translate) 　The Fukushima Daiichi Nuclear Power Station Unit 4 TEPCO continues to grow, including radioactive water contamination revealed that it rose about 20 cm in 10 days, the level of the turbine building. Well depth of about five meters underground reactor, and revealed to the Nuclear and Industrial Safety Agency Ministry of Economy, Trade and Industry that the 4000 tons of water contaminated water has accumulated, new challenges have emerged as the action.

　TEPCO has working to move waste disposal concentrate contaminated water high levels of Unit 2, the amount of capacity of the facility is expected to be about half the initial prospect of water treatment pollution of the No. others stand not.

　According to TEPCO, the No. 4 turbine building basement depth is 0.9 m to 13, 1.1 m at 6 pm on October 22. Rose to about 20 cm to 10 days. In the adjacent Unit 3 reactor per hour for irrigation has been 6.8 tons. TEPCO water leaking from the furnace, which sees three or four leaks or cracks in the wall separating the Unit 4 turbine building of the Unit.

Another Yoimuri through google translate: 　TEPCO press conference on April 22, at the bottom of the chamber pressure suppression containment Fukushima Daiichi Unit 1 nuclear power plant, said it was believed to have been nearly filled with water.

　Also called a dry well the top half, is expected to have a lot of water, fill with water completely flooded the containment of fuel to the "coffin" water will be virtually ongoing process.

　Pressure suppression chamber is typically contain about 50 percent of the water and become very high pressure inside the pressure vessel, steam led internally through the valve, cooling water, lowering the pressure of the agglomerated whole. Unit 1 pressure vessel, water has been injected into about 7,000 tons so far, TEPCO, almost all of this water, which is expected to remain within the containment.

　Unit 2 and 3 containment capacity (about 7000 tons) more than 14,000 tons, and tons of water injection is 9600, and by the pollution damage in the containment pressure suppression chamber, and flows into the turbine building it is likely.

SARbot searches for victims underwater in Japan
Joining the extended family of robots assisting with the relief effort in Japan, the Texas-based Center for Robot-Assisted Search and Rescue (CRASAR) has sent its SARbot to Rikuzentakata. Like some of the other bots, this guy can shoot video as it swims under houses and other crippled structures, but it also sports a "limb grasping mechanism," designed to retrieve drowning victims and assist in other search and rescue operations. As of yet its searches have come up empty, but the bot has kept the camera rolling during its underwater adventures, so head past the break to check out a clip of its footage. http://www.engadget.com/2011/04/22/sarbot-searches-for-victims-underwater-in-japan-video/
