Don't stigmatise nuclear evacuees, says Japan govt

Workers at Japan nuclear plant pump out toxic water
Tokyo (AFP) April 19, 2011 - Workers at a quake-hit nuclear plant in Japan on Tuesday began removing highly radioactive water from a reactor turbine building, a key step towards restoring cooling systems, the government said. The 9.0-magnitude earthquake and tsunami that hit the northeast coast of Japan on March 11 knocked out power systems at the Fukushima Daiichi plant, causing cooling systems to fail and triggering a series of explosions. To prevent a nuclear catastrophe, crews have pumped thousands of tonnes of seawater and later freshwater into the reactors and pools, creating a massive amount of radioactive runoff, some of which has leaked into the ocean. About 10,000 tonnes of highly radioactive water will be transferred from the turbine building of reactor no. 2 to a treatment facility inside the plant for processing, Japan's Nuclear and Industrial Safety Agency (NISA) said.

NISA spokesman Hidehiko Nishiyama said the operation would allow emergency crews battling to stabilise the plant to "pour more water into the reactor in order to gradually decrease the amount of water dousing". "We expect to purify and remove salt from water transferred to the waste treatment facility so that it can be poured into the reactor core again." The move is necessary in order to start work to restore cooling functions at the nuclear plant, where workers have found turbine buildings, trenches and shafts submerged in highly radioactive water. Tens of thousands of people living near the 1970s-era plant have been forced to evacuate their homes as radiation has leaked into the air, soil and sea. Embattled operator Tokyo Electric Power Company said Sunday it hopes to reduce radiation leaking from the plant in three months and to achieve "cold shutdowns" of all reactors within six to nine months.

Tokyo (AFP) April 19, 2011
The Japanese government on Tuesday urged "heartless" people, local authorities and businesses not to discriminate against evacuees from the area around the crippled Fukushima nuclear plant.

The call came after some evacuation centres demanded radiation-free certificates from people who lived near the plant, and following reports that hotels have turned them away and their children have been bullied.

"I cannot stress enough how regrettable it is that some heartless people have acted like that," said Koichiro Genba, a state minister for national policy.

"I want industries and central offices and agencies to give instructions to prevent such incidents from occurring."

The top government spokesman Yukio Edano said: "As an objective fact, radioactivity is not anything contagious like infectious diseases."

Such discriminatory acts "are obviously overreactions," said Edano, the chief cabinet secretary.

Since the March 11 earthquake and tsunami triggered the world's worst nuclear crisis since Chernobyl, nearly 86,000 people have had to evacuate, with about 30,000 of them relocated outside Fukushima prefecture.

They include residents from inside a 20 kilometre (12 mile) radius around the Fukushima plant.

More than five weeks since the accident, several cases have emerged in which people from Fukushima have faced discrimination.

In one case that surfaced Tuesday, the city of Tsukuba, Ibaraki prefecture, has required anyone from Fukushima prefecture to go through radiation checks and submit medical papers before being accepted into shelters.

Tsukuba's mayor Kenichi Ichihara later apologised, telling reporters he was sorry "that inadequate measures taken by Tsukuba city have caused problems and misunderstandings for people who have been evacuated."

Radiation release from Fukushima won't increase much: IAEA
Vienna (AFP) April 19, 2011 - The overall release of radiation from Japan's tsunami-hit nuclear plant will not increase much between now and when it is finally brought under control, the UN atomic watchdog said Tuesday.

Japan has been working feverishly to bring the Fukushima Daiichi nuclear power plant, 250 kilometres (155 miles) northeast of Tokyo, into safe shutdown since it was hit by a 14-metre (46-foot) tsunami on March 11, triggering the world's worst nuclear accident since Chernobyl.

The plant's operator, Tokyo Electric Power Company (TEPCO), said on Sunday it aims to reduce radiation leaks within three months and to achieve a so-called "cold shutdown" within six to nine months.

So far, the overall radioactivity release has been around 10 percent of that seen at Chernobyl 25 years ago, the Japanese authorities have said.

And the International Atomic Energy Agency's head of nuclear safety, Denis Flory, said the amount would not increase much further.

"There has been high bursts of radioactivity from the beginning," Flory told a regular news briefing here.

Currently, radioactivity was still leaking "at low level" but those leaks were decreasing.

"So, taking into account all the measures that are foreseen, the new amount of release will be decreasing and decreasing, and the total amount would not be much different from what it is today," the expert said.

According to Japanese estimates, the total radiation release at Fukushima so far has been 370,000 terrabecquerels, compared with 5.2 million terrabecquerels at Chernobyl.

Asked whether TEPCO's six-to-nine-month timeframe for achieving a cold shutdown was realistic, Flory replied: "Whether they will be able to keep (to) this ... will be shown by the facts."

Nevertheless, it was "very positive" that such a timetable had been set out at all, the expert added.

The IAEA's role over the next six to nine months would remain what it has been so far, that is to "share information," Flory continued.

The watchdog would, however, send a team of international experts on a first fact-finding mission to Fukushima before June, he said.

And further follow-up missions would follow, Flory added.

The IAEA is to host a ministerial-level summit from June 20-24 to try to examine the lessons learned from the Fukushima crisis.

Robot readings in Japan nuke plant 'harsh'
Tokyo (UPI) Apr 18, 2011
Remote-control robots at the quake-damaged Fukushima nuclear plant in Japan have measured a "harsh environment" for humans to work in, officials said. The measurements, which will complicate efforts to stabilize the damaged reactors, came a day after the company operating the Fukushima Daiichi plant said it would take until the end of the year to bring the crisis under control, the BBC ... read more
