Tokyo Electric Power Company's (TEPCO) disaster-readiness plans for Fukushima, which was slammed by Japan's March 11 twin earthquake and tsunami disasters, were obtained by Wall Street Journal.

The documents, said the financial daily, focused on smaller-scale accidents but no information on how to confront extensive damage.

According to the Journal, the plans had no detail on outside firefighters from Tokyo, the national military force, or using US equipment to battle leaks and contain radiation, which all have been part of the response to the crisis.

"The disaster plan didn't function," said a former TEPCO official, quote by the Journal. "It didn't envision something this big."

The revelations add to Japanese suspicion over TEPCO's track record on safety issues surrounding Fukushima and attempts to cover them up.

In 2002 TEPCO admitted to falsifying safety reports which led to all 17 of its boiling-water reactors being shut down for inspection, including Fukushima. And in an eerily familiar event, a 2007 earthquake paralyzed its Kashiwazaki-Kariwa nuclear plant -- the world's biggest -- and more radiation leaked than TEPCO initially acknowledged.

TEPCO later said it underestimated the potential impact of an earthquake on the facility.

On Thursday Japanese officials were saying there no plans to widen an exclusion zone around the stricken plant, amid revelations that radiation levels in the sea near the plant had risen to a new high of 4,385 times the legal level.

Japan says no need to evacuate village near nuclear plant
Tokyo (AFP) March 31, 2011 - Japan's nuclear safety agency said Thursday there is no need to evacuate a village 40 km (25 miles) from the crippled Fukushima nuclear plant after the UN nuclear watchdog voiced concern.

The International Atomic Energy Agency (IAEA) earlier said radiation levels taken at Iitate, located well outside Japan's 20km exclusion zone from the stricken facility, were above its evacuation level.

But Japan's nuclear safety agency said there was no need for the several thousand people still in the village northwest of the plant to leave.

"The IAEA notice was based on a limited sample and a single reading," agency official Yoshihiro Sugiyama told AFP.

"It had an explanatory note that it is necessary to closely follow the situation. We also acknowledge the need to closely follow the situation.

"But at the moment, we do not have the understanding that it is necessary to evacuate residents there. We think the residents can stay calm."

Authorities later said they would Friday lift restrictions issued earlier on drinking tap water in the village, public broadcaster NHK reported.

Norio Kanno, the mayor of the village, which had a pre-disaster population of 6,000, said he was initially "very worried" about the IAEA warning, NHK reported on its website.

"But the government immediately informed us that there is no immediate harm to human health, so I was relieved," he said.

"Villagers have voiced concern, but the levels of radiation in the tap water and the air are declining. I will carefully monitor them before taking any actions."

The Fukushima plant was crippled by a tsunami on March 11 and hit by several explosions, leading to frantic efforts to prevent a catastrophic meltdown as radiation has wafted into the air and seeped into the ocean.

Japan has imposed a 20 km exclusion zone around the plant, and also urged people within 30 km to move away.

According to Elena Buglova, head of the IAEA's Incident and Emergency Centre, the reading in Iitate village was 2 megabecquerels per square metre.

That was a "ratio about two times higher than levels" at which the agency recommends evacuations, she said.
