TEPCO starts up water treatment system, but massive radioactive waste feared
Tokyo Electric Power Co. (TEPCO) began a trial run of a radioactive water treatment system at the crippled Fukushima No. 1 Nuclear Power Plant on June 15 in a desperate effort to break away from the vicious cycle of injecting water into reactors to cool them and ending up with more contaminated water.
But even if the system, developed by France's Areva SA, were to operate smoothly, it would produce a massive amount of high-level radioactive waste that could affect TEPCO's roadmap to bring the troubled nuclear reactors under control by early next year.
"The water treatment system is moving along as scheduled, although contaminated water leaked from a pipe," Hidehiko Nishiyama, spokesman for the Nuclear and Industrial Safety Agency, told a news conference on June 15.
TEPCO, the operator of the troubled Fukushima No. 1 Nuclear Power Plant, will try to reach "Step 1" of the roadmap, in which radiation emissions are steadily declining, by mid-July. It hopes to reach "Step 2," in which leakages of radiation are controlled and amounts of radiation are drastically reduced, within three to six months...

Evacuation urged for radioactive hot spots
Recommendation to leave limited areas outside 20-km zone won't be mandatory
By MASAMI ITO
Staff writer
The government decided Thursday to encourage the evacuation of residents living in radioactive hot spots outside the no-entry zone around the Fukushima No. 1 nuclear plant.
In-depth monitoring by the government found the hot spots outside the 20-km evacuation zone in numerous places, including in Date and Minamisoma in Fukushima Prefecture where levels of radiation exceeded the equivalent of 20 millisieverts per year.
According to Chief Cabinet Secretary Yukio Edano, the results of the monitoring showed that the hot spots were limited in scope, unlike the situation in the evacuation zone, and therefore the government determined that "an across-the-board evacuation or restrictions of industrial activities" were unnecessary.
But at the same time, Edano explained that the government decided to encourage their evacuation because it couldn't completely rule out the possibility of residents being exposed to more than the 20-millisievert benchmark…

The operator of the Fukushima Daiichi nuclear plant is under pressure to ensure the flawless operation of a system to decontaminate radioactive water, which threatens to overflow.
More than 110,000 tons of the highly radioactive water has accumulated in the nuclear complex.
The amount is growing by 500 tons a day as fresh water is injected into reactors to cool them down...
...TEPCO has also yet to decide how to dispose of radioactive waste generated during the decontamination process.

The Iwate Prefectural Government has again detected a radioactive substance above the state limit in pasture grass in several areas in the prefecture. The prefecture asked farmers in the areas to refrain from feeding the grass to their livestock.
The prefectural government found on Tuesday radioactive cesium exceeding the limit of 300 becquerels per kilogram in grass collected from pastures in four areas, including Tono and Otsuchi. The areas are located about 150 to 200 kilometers north of the Fukushima nuclear power plant.
The Iwate government plans to conduct more detailed examinations in the four affected municipalities...
...High levels of radiation in pasture grass have also been reported in Fukushima Prefecture, which hosts the troubled nuclear plant, and neighboring prefectures.

Naoto Kan may leave a lot to be desired as a prime minister, but one thing's certain--he's never taken a dime from Tokyo Electric Power Co., the operator of the Fukushima No. 1 nuclear power plant.
Kan's complete independence from TEPCO money--and pressure--may be the real reason so many lawmakers are trying to push him out the door. His calls to shift Japan away from nuclear energy and to break TEPCO into separate companies that handle power generation and power transmission threaten some very powerful special interests.
There are many lawmakers in both the ruling Democratic Party of Japan and the opposition Liberal Democratic Party who have taken TEPCO money for years and feel obligated to protect the company's interests.
The confrontation between those who want to protect TEPCO and those in government who want to drastically reform the company heated up from May 24 when the Kan Cabinet approved the establishment of two committees related to TEPCO…
