TEPCO restarts decontamination system
The operator of the Fukushima Daiichi nuclear power plant has restarted a system to decontaminate highly radioactive water after an 8-hour halt to replace a faulty part.
Tokyo Electric Power Company had stopped running the system on Tuesday morning after workers spotted a leak from a joint that connects a pipe. The pipe feeds chemicals to a French-made device designed to break down radioactive materials.
TEPCO says the original metal joint was corroded by the chemicals and that it has now replaced it with a stainless-steel part.
The original joint had been replaced with a polyvinyl joint only 2 days ago due to another leak.
The decontamination facilities are a key part of TEPCO's plan for treating and recycling radioactive water as coolant inside the disabled reactors.
But the system has suffered one problem after another, raising question about TEPCO's announced target of stably cooling the reactors by July 17th, the first step in its plan to bring the plant under control.
Also on Tuesday, TEPCO completed work to connect pipes for the injection of nitrogen into the containment vessel of the No. 3 reactor to prevent a hydrogen explosion.
The utility plans to start nitrogen injections in a few days after receiving approval from the government's Nuclear and Industrial Safety Agency.

Niveau record de radiation à Fukushima
01 août 2011 Usine Nouvelle
Plus de quatre mois après le séisme, des radiations plus puissantes que jamais ont été mesurées sur le site de la centrale de Fukushima.
Tepco a annoncé cette nouvelle alarmante le premier août : des rayonnements d'un niveau de 10 sieverts par heure ont été mesurés entre les réacteurs un et deux de la centrale de Fukushima Daiishi. Le précédent niveau record a été mesuré le 3 juin, il était de trois à quatre sieverts par heure. Et on l'avait relevé à l'intérieur du réacteur un.
"Nous sommes toujours en train de vérifier la cause de tels niveaux élevés de radioactivité", a expliqué une porte-parole de Tepco, la société japonaise exploitante du site. Le gouvernement japonais a affirmé récemment que les niveaux de radiations aux alentours de la centrale avaient chuté à un niveau identique à deux millionièmes du pic enregistré le 15 Mars.
Le gouvernement et Tepco prévoient toujours de stabiliser la situation en conduisant les réacteurs vers un état dit d'"arrêt à froid" d'ici au mois de janvier. Pour refroidir le combustible nucléaire, plusieurs actions ont été entreprises, notamment la mise en place d'un système de circulation d'eau de refroidissement.
Tokyo Electric Power Co., operator of Japan's crippled Fukushima Dai-Ichi nuclear plant, said it detected the highest radiation to date at the site.
Geiger counters, used to detect radioactivity, registered more than 10 sieverts an hour, the highest reading the devices are able to record, Junichi Matsumoto, a general manager at the utility, said today. The measurements were taken at the base of the main ventilation stack for reactors No. 1 and No. 2.
Remember all those idiots who claimed that Fukushima is contained, or better yet, the drama is exaggerated? Perhaps it is time to exile them all, starting with that moron from MIT, to Fukushima where the radiation measured at the base of the main ventilation stack just hit an all time high 10 sieverts/hour. The truth likely is much uglier: this is simply the highest reading the devices are able to record. In other words, there does not exist a device that can capture the true extent of the catastrophe at Fukushima!
From Bloomberg:
“I suspect the high radiation quantity was an aftermath of venting done,” Matsumoto told reporters in Tokyo. “The plant is not running. I don’t think any gas with high radiation level is flowing in the stack.” ??????????????????????????
Tepco sent three workers around the ventilation stack today after a gamma camera detected high radioactivity levels in the area yesterday, Matsumoto said. The workers were exposed to as much as 4 millisieverts during the work, he said.
The utility will create a no-go zone around the stack and cover the area with protective material, he said.

Iwate to join cattle ban; hundreds more suspected tainted
Kyodo
SAGA — The government decided Sunday to ban shipment of all beef cattle from Iwate Prefecture after cesium above the government limit of 500 becquerels per kilogram was found in the meat of a sixth animal, sources said.
The order, based on a special law on nuclear power plant-related accidents, is expected to be officially issued on Monday.
Iwate will be the third prefecture banned from shipping cattle after Fukushima and Miyagi, but Tochigi Prefecture could be banned Monday as well, they said.
The Health, Labor and Welfare Ministry said Iwate ships about 36,000 beef cattle annually, including those used for Maezawa Gyu, one of the top brands.
In Iwate, beef samples taken from six cattle have tested positive for radioactive cesium above the safety limit of 500 becquerels per kilogram. The cows were found to have eaten cesium-tainted rice straw in Ichinoseki and Fujisawa.
On Saturday meanwhile, more beef cattle were confirmed to have been shipped for slaughter after being fed cesium-tainted rice straw, with 290 from Fukushima Prefecture and 103 from Miyagi Prefecture, local officials said.
A sample taken from one of the animals contained 655 becquerels, while other meat made from it is believed to have been consumed after being shipped last month to Tokyo.
The contamination was traced to the rice straw, which had been stored outdoors in the weeks after the Fukushima No. 1 power plant suffered a series of explosions after the March 11 earthquake that flung alarming amounts of radioactive material into the atmosphere.
The Fukushima Prefectural Government said the number of suspect cattle shipped to market now stands at 872.
The 290 newly suspected cattle were shipped from Fukushima — home of the crippled nuclear power plant — to slaughterhouses in Tokyo, Saitama and Kanagawa prefectures. Fukushima authorities are belatedly asking those prefectures to trace where the meat was distributed.
Earlier this month the government ordered Fukushima to stop shipping beef cattle to market, and authorities are preparing to slaughter about 700 local cattle by the end of August and to test meat from all of them for radioactive contamination.
In neighboring Miyagi Prefecture, the local government said the 103 additional cattle bring the local tally of potentially contaminated cattle to 1,134, with animals shipped to Tokyo, Iwate, Miyagi, Chiba, Yamagata and Niigata.
But it said none of 17 cattle tested Friday and Saturday had cesium above the state limit.
