TEPCO finds own nuclear accident manual useless

TOKYO, Oct. 2, Kyodo

Tokyo Electric Power Co.’s in-house report showed Sunday the utility has found its own emergency manual was useless for handling the crisis at the Fukushima Daiichi nuclear plant and also repudiated the widely-held belief that a hydrogen explosion might have occurred at its No. 2 reactor.

The report indicated the utility prepared the manual with a view to dealing with nuclear plant accidents including severe incidents on the assumption that emergency power generators, including diesel generators, would work properly to keep reactor cooling systems functioning.

In fact, none of the backup generators worked after the March 11 earthquake and tsunami hit the plant located on the Pacific coast.

Go ahead and send the folks back to their homes. Relax, nothing can go wrong. There is no immediate danger. Radiation only affects those who don’t smile…

Fukushima plant crisis could erupt if water injection stops for 38 hrs

http://mdn.mainichi.jp/mdnnews/news/20111002p2g00m0dm021000c.html

TOKYO (Kyodo) — Tokyo Electric Power Co. has released an estimate that says if water injection at its stricken Fukushima No. 1 Nuclear Power Plant stops, its fuel rods could start melting in 38 hours, causing radioactive substances to spew out.

The utility said, however, it can resume watering at the Nos. 1 to 3 reactors in three hours at the most in case the plant is hit by another earthquake and tsunami matching the scale of the March 11 disaster that caused their core meltdowns.

The estimate said the temperature of the fuel, now believed to have solidified at the bottom of the reactors’ pressure vessels, would rise about 50 C each hour and reach its melting point of 2,200 C in about 38 hours.

The reactors would then start emitting massive amounts of radioactive substances, raising the radiation level around the plant’s premises above 10 millisieverts, the benchmark for prompting an order to evacuate.

In the estimate, TEPCO did not assess the likelihood of any melted fuel dropping through the pressure vessels into the containment vessels shrouding each reactor.

In the case any one part of the current system used to pump water into the crisis-hit reactors is lost, TEPCO said it can resume watering in about 30 minutes by activating emergency pumps installed at an elevated position. In the event of multiple functions were lost, the utility projected it would require about three hours to resume injecting water.

TEPCO official Junichi Matsumoto said the utility would inject boric acid if there were a concern of a nuclear chain reaction. But he said the likelihood of such a reaction occurring was small because the condition within the reactors has changed as the fuel was damaged.

[and as a reminder…. this clip from a Scientific American report from April 2011]:

When Will Japan’s Aftershocks Stop?

After the magnitude 7.1 aftershock, a seismologist explains why Japan’s seismic future looks even more uncertain than it did before the massive March earthquake

http://www.scientificamerican.com/article.cfm?id=japan-aftershocks

[snip]

On average, about one in 20 earthquakes is a foreshock, and there’s actually a chance that this 9 was a foreshock. But it’s not a very high probability given this sequence of earthquakes. 

This sequence is pretty special, though, because the Japan Trench is one of the world’s most active subduction zones. But historically there’s been relatively little seismic activity on the trench compared to the relative activity on the fault. Because there’s been little activity in the trench, the Japanese seismologists had classified it as a relatively low hazard area. But several Western seismologists had questioned that, including me. 

If it’s been locked for 1,000 years, then it implies a tremendous amount of accumulated strain in the region. And the earthquake doesn’t seem to be big enough to account for the accumulated strain. We’re still left with the question: Where do we put the remainder of the slip of the fault?

3/11 a lesson in hospital vulnerability

Quake-proofing, backup power now key goals, if there’s funds

Staff writer

Urban hospitals represent vital infrastructure, especially when a major disaster strikes.

But the March 11 magnitude-9 earthquake and tsunami that hit the Tohoku region showed their vulnerabilities, as many sustained damage and power outages that hampered their ability to function.

Experts are urging that hospitals prepare for another megaquake as soon as possible, including in Tokyo, which reportedly faces a 70 percent risk of a magnitude-7 temblor sometime in the next 30 years. This threat has prompted projects to make all of the area’s medical institutions quake-proof by 2016.

In August, the Tokyo Metropolitan Government introduced an emergency plan to provide financial assistance to all hospitals that are not strong enough to withstand a quake of upper 6 on the Japanese seismic scale to 7, to cover reinforcement work. The strongest temblor recorded on land on March 11 was 7 in Miyagi Prefecture.

A 2010 Health, Labor and Welfare Ministry survey found 43.8 percent of hospitals nationwide were not strong enough to withstand a really big quake. Out of 625 Tokyo hospitals responding to the poll, 53.9 percent said they are quake-resistant.

News: One of the worst hottest spots is in front of Japanese Diet

Posted by Mochizuki 

Japanese politicians finally got radiation.

According to the local radiation survey on 10/1/2011,the area around Japanese diet is obviously hot spot.

In front of Tokyo station, 0.267 uSv/h

In front of Imperial Palace, 0.676 uSv/h

Mud in Diet, 0.456 uSv/h

Dust in Hibiya park, 0.457 uSv/h

In front of Tepco’s head office, 0.463 uSv/h

Plutonium detected in soil outside Fukushima nuclear plant

NATIONAL OCT. 01, 2011 – 03:00PM JST ( 56 )

TOKYO —

A limited amount of plutonium has been detected in soil outside Japan’s troubled Fukushima nuclear power plant which was crippled by the March 11 quake-tsunami disaster, the government said Friday.

It was the first time plutonium had been found in government tests outside the plant, presumably due to the nuclear accident, the education and science ministry said in a statement.

Plutonium was detected in soil at six places in a survey which was conducted in June in an area within 80 kilometers from the Fukushima Daiichi plant, the ministry said.

Nuclear reactors at the plant suffered meltdowns after cooling systems there were knocked out by the double disasters. Plutonium has been already detected in the plant’s compound, some 220 kilometres from Tokyo.

The highest density of plutonium-239 and 240—4.0 becquerels per square meter—was registered in a town some 30 kilometres from the plant, the ministry said.

In a village 45 kilometers away, the reading was 0.82 becquerels per square metre.

Plutonim has previously been detected in Japan following atmospheric nuclear tests, the ministry said.

The average density of plutonium, which was detected in soil samples between 1999 and 2008 in Japan, was 0.498 becquerels, the ministry said. The highest reading before the Fukushima accident was 8.0 becquerels.

“The plutonium density, which was detected this time, was within the range of past readings. So the dose of radiation is deemed very small,” the ministry said.

Plutonium is formed from uranium in nuclear reactors and generally stays in the body for decades, exposing organs and tissues to radiation and increasing the risk of cancer, experts say.

Right. Everybody buy one of these and we can all float off to an island somewhere in the Pacific. Wait, we ARE on an island in the Pacific. Maybe the next one won’t be on four active earthquake plates with 54 nuclear reactors on it…

TOKYO (AP) — A small Japanese company has developed a modern, miniature version of Noah’s Ark in case Japan is hit by another massive earthquake and tsunami: a floating capsule that looks like a huge tennis ball.

Japan’s Cosmo Power says its “Noah” shelter is made of enhanced fiberglass that can save users from disasters like the one on March 11 that devasted Japan’s northern coast, leaving nearly 20,000 people dead or missing.

Company president Shoji Tanaka says the $3,900 (300,000 yen) capsule can hold four adults, and that it has survived many crash tests. It has a small lookout window and breathing holes on top. It also can be used as a toy house for children.

The company already has delivered two capsules and has orders for 600 more.

Huh? You mean there’s enough? (electricity) AND WE DIDN’T HAVE TO GO THROUGH WHAT WE’RE GOING THROUGH WITH RADIATION SPREAD AROUND JAPAN AND THE NORTHERN HEMISPHERE?

Hmmm, someone should have explained that to the people BEFORE the plants were built, donchya think?

Anyway, a group selling bright T-shirts is making a valiant attempt to undo what has been done in terms of making people realize there is no need for nuclear power in Japan.
