TOKYO: Reuters: May 26, 2011 - Radioactive water appears to be leaking from a waste disposal building at Japan's Fukushima nuclear complex, operator Tokyo Electric Power said on Thursday, in a new setback to the battle to contain radiation from the crippled power plant.
The disclosure by Tepco raises the stakes in a race to complete by next month a system to decontaminate a massive pool of radioactive water at the site that critics see as a growing risk to both the nearby Pacific and groundwater.
A magnitude 9.0 earthquake and the massive tsunami that followed killed about 24,000 people and knocked out the Fukushima plant on March 11, triggering the world's worst nuclear accident since Chernobyl.
The crisis, which has displaced some 80,000 residents from around the plant, prompted a review of Japan's energy policy and growing calls for efforts to step up health monitoring for a crisis now in its 11th week.
Experts from the International Atomic Energy Agency began an inspection on Thursday of equipment damaged by the tsunami at a second nuclear plant, the Tokai complex about 120 km (75 miles) north of Tokyo, as part of an investigation prompted by the Fukushima accident.
A poll by the Asahi newspaper published on Thursday showed that 42 percent
of Japanese people opposed nuclear power, up from 18 percent before the
The survey underscored the public's deepening concerns about nuclear safety and criticism of the way the government and Tepco initially responded to the crisis and how they appeared to have been repeatedly slow in admitting the gravity of the situation.
Although many outside experts had concluded that uranium fuel in three Fukushima reactors had melted down within days of the crisis, Tepco only announced that conclusion this week.
"We have to take seriously the criticism that we haven't done enough to provide and circulate information," Chief Cabinet Secretary Yukio Edano said at a news conference. "But we have never covered up information that we had."
The effort to regain control of the plant relies on pumping massive quantities of water to cool the three reactors that suffered meltdowns and storing the contaminated water in an improvised storage facility. Tepco officials said, however, that the water level in the storage facility had dropped, suggesting a leak.
Environmental groups have focused on the threat to sea and ground water from the accident. Greenpeace said earlier this month it had collected samples of fish, seaweed and shellfish along the Fukushima coast that showed radiation levels above Japanese safety limits.
Residents of the town of Futaba, forced to evacuate along with others inside a 20-kilometre (12-mile) zone around the plant, were allowed to return briefly to their homes on Wednesday.
A day earlier, residents of the nearby town of Minami Soma had been allowed back to their homes for a two-hour visit wearing hooded white protective suits, masks and goggles.
Video shot by a couple returning home and broadcast on Japanese television showed a ghost town with weeds overrunning a garden and a stray dog barking in the distance.
"It didn't even feel like my own home," one woman told Nippon Television. "I thought I was prepared for that, but I wasn't."
Greenpeace warns of radioactive sea life off Japan
May 26, 2011 - Environmental activist group Greenpeace warned Thursday that marine life it tested more than 20 kilometres (12 miles) off Japan's stricken Fukushima nuclear plant showed radiation above legal limits.
The anti-nuclear group, which conducted the coastal and offshore tests this month, criticised Japanese authorities for their "continued inadequate response to the Fukushima nuclear crisis" sparked by the March 11 quake and tsunami.
Greenpeace said it detected seaweed radiation levels 50 times higher than official limits, which it charged raised "serious concerns about continued long-term risks to people and the environment from contaminated seawater".
It also said that tests, which it said were independently verified by French and Belgian laboratories, showed above-legal levels of radioactive iodine-131 and caesium-137 in several species of fish and shellfish.
"Our data show that significant amounts of contamination continue to spread over great distances from the Fukushima nuclear plant," said Jan Vande Putte, a Greenpeace radiation expert, at a Tokyo press conference.
Japan has said ocean currents and tides are rapidly diluting contaminants from the tsunami-hit atomic plant, and Fukushima prefecture told AFP on Thursday that no fishing is going on at the moment in its waters.
"We have exercised self-restraint as (prefectural) safety tests have not been conducted yet," said a Fukushima official. "We will make a decision after confirming the results of the tests, which will take place shortly."
The official added: "People do not bother fishing now. If you caught fish or other marine products in waters near the plant, they wouldn't sell."
Japan's fisheries agency, and neighbouring prefectures, have been checking marine products at different spots, and the government has prohibited fishermen from catching some species found to have elevated radiation levels
