News about nuclear accident in Fukushima in June 2011
- High levels of strontium detected at Fukushima
The operator of the Fukushima Daiichi nuclear power plant says it has detected high levels of a radioactive substance that tends to accumulate in human bones. Tokyo Electric Power Company says it took soil samples on May 9th at 3 locations about 500 meters from the No.1 and No.2 reactors and analyzed them. The utility detected up to 480 becquerels of radioactive strontium 90 per kilogram of soil. That's about 100 times higher than the maximum reading recorded in Fukushima Prefecture following atmospheric nuclear tests carried out by foreign countries during the Cold War era. TEPCO reported detecting 2,800 becquerels of strontium 89 per kilogram of soil at the same location.
- Utilities report 342 faults near nuclear plants
Japan's electric power companies have reported 342 faults and geographical changes near nuclear power plants that they previously did not consider to be risks.
- Some Fukushima soil same as Chernobyl 'dead zone'
Soil samples in areas outside the 20-km exclusion zone around the Fukushima plant measured more than 1.48 million becquerels per sq. meter, the standard used for evacuating residents after the Chernobyl accident, Tomio Kawata, a fellow at the Nuclear Waste Management Organization of Japan, said in a research report published May 24 and given to the government. Radiation from the plant has spread over 600 sq. km, according to the report. The extent of contamination shows the government must move fast to avoid the same future for the area around the Fukushima plant as Chernobyl, scientists said.
- Reactor in Shimane delayed for safety work
The utility postponed the start of operations for the No. 3 reactor at the Shimane nuclear plant in the city of Matsue until after next April. It was originally scheduled for next March. The nuclear complex is located on the coast of the Sea of Japan.
- Chernobyl 'jumper' airs Fukushima fears
"The reason why I am so affected (by the Fukushima disaster) is that I feel for these guys who work at the station as jumpers because every day goes by they will have much more effort to clean it up and more health and lives will be lost." Belyakov has been monitoring the developments at Fukushima every day since the plant was struck by the March 11 earthquake and tsunami. He added that he believes the Japanese government should have immediately sought assistance and advice from those who had direct experience in dealing with the Chernobyl catastrophe. "To me it is quite unexplainable that Tokyo Electric Power Co. and, obviously, the Japanese government do not tap into the pool of knowledge of people who went through Chernobyl and can lend them a hand with a lot of help," he said
- Opera stars, fearing radiation, cancel
Two of the biggest stars of New York's Metropolitan Opera have bowed out of a Japan tour, citing fears of radioactive contamination and sending the company scrambling to find last-minute stand-ins.
- Fukushima Workers Exposed To High Radiation; Less Than 40% Of About 3,700 Workers Tested
- TEPCO probes into possible leak at Fukushima
The operator of Japan's troubled nuclear plant is trying to determine where contaminated water from a waste disposal facility is leaking to, after finding that the water level inside the facility has dropped.
- Containment vessels also damaged
The Yomiuri Shimbun Not only the pressure vessels, but the containment vessels of the Nos. 1 to 3 reactors at the Fukushima No. 1 nuclear power plant were probably damaged within 24 hours of the March 11 earthquake and tsunami, according to Tokyo Electric Power Co.'s analysis of the nuclear crisis.
- Tropical Storm Songda Hits Japan Region Still Reeling From Earthquake and Tsunami
Heavy rains and strong winds battered the northeast coast of Japan Monday as Tropical Storm Songda touched down on a region still reeling from a massive earthquake and tsunami, triggering mudslides and widespread flooding that forced the operator of the crippled Fukushima nuclear reactor to suspend outdoor work.
- No.5 reactor temperature rises after pump failure
On Sunday morning, TEPCO installed a new pump that started operating shortly after noon. The company suspects failure in the pump motor caused the malfunction. It is now working to detect the cause of the failure while monitoring temperatures in the reactor and pool.
