Japan Utility Ordered to Review Soaring Radiation Figures

TOKYO -- Japan's nuclear safety agency ordered a review Friday of the latest radiation measurements taken in air, seawater and groundwater samples around a leaking, tsunami-disabled nuclear plant, saying they seemed suspiciously high.

Among the measurements called into question was one from Thursday that TEPCO said showed groundwater under one of the reactors contained iodine concentrations that were 10,000 times the government's standard for the plant, the safety agency's spokesman Hidehiko Nishiyama said. Seawater and air concentrations from this week also are under review.

"We have suspected their isotope analysis, and we will wait for the new results," Nishiyama said, adding that the agency thinks the numbers may be too high.

TEPCO has conceded that there appears to be an error in the computer program used to analyze the data and that recent figures may be inaccurate. They have indicated they are probably too high but have also said that the figures may be correct, despite the glitch.

URGENT: Gov't eyes injecting nitrogen into reactor vessels to prevent blasts

TOKYO, April 1, Kyodo

The government and Tokyo Electric Power Co. are considering injecting nitrogen into containment vessels of the Fukushima Daiichi nuclear power plant's reactors to prevent hydrogen explosions, government sources said Friday.

==Kyodo

LN2 boils at -196C/-321F. It also has a very low heat capacity, it doesn't seem that it would be an effective coolant at this point..

Can anyone speak to this further?

Probably in a compressed state?

TOKYO — It's a job that sounds too good to be true — thousands of dollars for up to an hour of work that often requires little training.

But it also sounds too outrageous to accept, given the full job description: working in perilously radioactive environments.

In its attempts to bring under control its radiation-gushing nuclear power plant that was severely damaged by last month's massive earthquake and tsunami, Tokyo Electric Power Co. (TEPCO) is trying to get workers ever closer to the sources of stubborn radiation at the plant and end the world's worst nuclear crisis since Chernobyl.

"TEPCO said 18 employees and three contractors were exposed to 100 millisieverts of radiation on Friday. The average dose for a nuclear plant worker is 50 millisieverts over five years"

"

Asked on Monday how the contaminated water could be pumped out and how long it would take, a TEPCO official replied: "The pump could be powered from an independent generator, and all that someone would have to do is bring one end of the pump to the water and dump it in, and then run out."

Translation: Jumpers wanted"

I suggest reading the entire article.

It's something that most likely can't be avoided.

Just another version of the "Bio Robots" of Chernobyl.

Official: Radioactive water leaking into sea through crack in concrete

Tokyo (CNN) -- Power plant workers began filling a cracked concrete shaft with fresh cement to stop highly radioactive water from earthquake-damaged nuclear reactors from draining into the Pacific Ocean, Japanese regulators said Saturday.

Water from the 2-meter deep, concrete-lined basin could be seen escaping into the ocean through a roughly 20-cm (8-inch) crack, the Tokyo Electric Power Company told reporters Saturday afternoon. Electrical conduits run upward through the space, which lies behind the turbine plant of the No. 2 reactor at the Fukushima Daiichi nuclear plant.

Reactor Core Was Severely Damaged, U.S. Official Says

WASHINGTON — Energy Secretary Steven Chu said Friday that roughly 70 percent of the core of one reactor at the crippled Fukushima nuclear plant in Japan had suffered severe damage.

His assessment of the damage to Reactor No. 1 was the most specific yet from an American official on how close the plant came to a full meltdown after it was hit by a severe earthquake and massive tsunami on March 11.

Japanese officials have spoken of “partial meltdown” at some of the stricken reactors. But they have been less than specific, especially on the question of how close No. 1 — the most badly damaged reactor — came to a full meltdown.

First attempt to plug water leak unsuccessful.. still don't know where the water is coming from exactly..

http://www.cnn.com/2011/WORLD/asiapcf/04/02/japan.nuclear.reactors/index.html?hpt=T1

Snippet from link above:

Tokyo (CNN) -- A first attempt to plug a cracked concrete shaft that is leaking highly radioactive water into the ocean off Japan failed Saturday, so officials are now exploring alternatives, spokesmen for Tokyo Electric Power Co. said.

Power plant workers had been trying to fill the shaft with fresh concrete, but that did not change the amount of water coming out of the crack, the spokesmen said at a news conference that ran late into the night Saturday.

Their "plan B" is to use polymers to stop the leak, the spokesmen said. A Tokyo Electric expert will visit the site Sunday morning and decide what polymer to use before the work begins.

Workers will then break the shaft's ceiling and insert the polymer in a different spot from where they tried to place the concrete, they said.

BreakingNews Breaking News Power company reports 2 missing Fukushima nuclear plant workers found dead on site - Kyodo News

From the wave, not radiation.

TOKYO – The utility that runs a tsunami-crippled Japanese nuclear power plant says two workers were killed when the wave swept ashore more than three weeks ago.

Tokyo Electric Power Co.'s announcement Sunday is the first confirmation of deaths at the plant.

The workers had been missing since the March 11 earthquake and tsunami.

Radiation Consultant Dr Ian Fairlie: Is there a danger of a radioactive cloud

as far away as California?..update.

Transcript Summary:

-- Is there a danger of a radioactive cloud as far away as California?

-- Really difficult to say…

-- Depends on the weather pattern, the wind direction…

-- Watch the weather patterns very carefully…

-- Children especially vulnerable…

They're using a mix of sawdust, newspapers, and a chemical that expands rapidly (in contact with water I assume). So not too far off from the junk shots...

Not nearly the same pressure as the BP Well, and with better access to the inside of the leak they maybe able to seal it off with pankake mix and toilet paper.

No radiation of consequence measured in the air over the US...

Daily Data Summary

Last updated on Saturday, April 02, 2011 at 7:24:21 PM.

As the Nuclear Regulatory Commission has said, we do not expect to see radiation at harmful levels reaching the U.S. from damaged Japanese nuclear power plants. As part of the federal government's continuing effort to make our activities and science transparent and available to the public, the Environmental Protection Agency (EPA) will continue to keep all RadNet data available in the current online database. EPA is working with its federal partners and has deployed additional monitors to Hawaii, Alaska, Guam and the Northern Mariana Islands.

EPA is utilizing this existing nationwide radiation monitoring system, RadNet, which continuously monitors the nation's air and regularly monitors drinking water, milk and precipitation for environmental radiation. The RadNet online searchable database contains historical data of environmental radiation monitoring data from all fifty states and U.S. territories.

EPA will provide daily data summaries of our radiation air monitoring efforts. We will continue to keep all RadNet data available in the current online database.

Just saw on CNN.: and I paraphrase " the Japanese gov't has given the ok to dump 10tons of radioactive water into the ocean"

10tons=20,000 lbs. 1lb of water =8lbs... 8lbs into 20,000= 2500 gallons.

The big questions here are:

1. Were the units converted correctly in the translation?? Seems to be an ongoing issue

2. Do they have an accurate measurement of the amount of water being released? You cAn get a good idea of how much water you can release through a controlled opening.

3. Is this a controlled dump ? Through a Gaye valve of some sort? Or is it free handed ?

4. Probably the most important question. What are the isotopes being dumped? Celsium? Iodine? Plutonium? They didn't say from what specific reactor site so I can't comment further in that sense.

Just some questions to ponder

5. Was this news source even credible? ;-)
