Japan earthquake: Radioactive leak plugged at reactor

A leak of highly radioactive water into the Pacific Ocean from Japan's crippled Fukushima Daiichi nuclear plant has been stopped, its operator reports.

Tepco said it had injected chemical agents to solidify soil near a cracked pit that was the source of the leak.


As this video shows, the crisis is far from over. I worry about the long term effects of all the marine life plus the time it takes for it to disperse enough to be almost harmless. or is is ever that? The ocean is huge but we are seeing the effects as far away as Russia. The Japanese are trying everything they know, but will it be enough? Time will tell.

This is the latest news about Fukushima

The operator of Japan's crippled Fukushima Daiichi nuclear plant has said it expects to bring the crisis under control by the end of the year.

Tokyo Electric Power Co (Tepco) aims to reduce radiation leaks in three months and to cool the reactors within nine months.

The utility said it also plans to cover the reactor building, which was hit by a huge quake and tsunami on 11 March.

Nearly 14,000 people died and another 14,000 are still unaccounted for.

Tepco unveiled its roadmap as Hillary Clinton briefly visited Tokyo to pledge America's "steadfast support" for Japan's reconstruction.

'Cold shutdown'

Radiation levels in the sea near reactor 2 rose to 6,500 times the legal limit on Friday, up from 1,100 times a day earlier, Tepco has said, raising fears of fresh radiation leaks.

A UK firm's robots, operated via a standard games console, will go into the reactor Tsunehisa Katsumata, the chairman of Tepco, Asia's largest utility, told a news conference in Tokyo on Sunday they would need up to nine months to bring the power plant to ''cold shutdown''.

He said the plan would allow the tens of thousands of families evacuated from the area around the facility to return home as soon as possible.

"We sincerely apologise for causing troubles," Mr Katsumata said. "We are doing our utmost to prevent the crisis from further worsening."

Tepco said after cold shutdown it would focus on encasing the reactor buildings, cleaning up contaminated soil and removing nuclear fuel.

Japan's government had ordered Tepco to come up with a timetable to end the crisis, now rated on a par with the world's worst nuclear accident, the 1986 Chernobyl disaster.

But the BBC's Roland Buerk in Tokyo says it is still not certain that the nine-month deadline can be achieved.

He says the immediate priority for Tepco is to stop radioactive water leaking into the Pacific Ocean.

The utility said it was sending remote-controlled robots into one of the reactors on Sunday to gauge radiation and temperature levels.

UK defence contractor QinetiQ said it had provided the machines, which are controlled using a standard games console.

The robots can carry out tasks such as rubble clearance, demolition and radiation testing.

Japan is a world leader in such technology, but its robots are not adapted for dirty work such as meltdowns at nuclear plants, experts say.

US thanked

Emergency workers have been unable to enter any reactor building since the disaster.

Before the disaster, Japan-US ties had been strained by a dispute over military bases Our correspondent says Japan's recovery bill has been estimated at $300bn (£184bn) - already the most expensive disaster in history.

But the government said last week that figure might be an underestimate.

Meanwhile, US Secretary of State Clinton said in Japan she believed the country would emerge stronger from its worst crisis since World War II.

She met Prime Minister Naoto Kan and had tea with Emperor Akihito at the Imperial Palace, said to be a rare privilege for a non-head of state on a Sunday.

America has won Japanese admiration for sending scores of US ships and aircraft as well as 20,000 troops to help the relief effort.

Operation Tomodachi, or Friend, was the biggest humanitarian mission the US has conducted in Japan.

Before the quake, the two nations' ties had been strained by a dispute over US military bases on the southern Japanese island of Okinawa.

Mr Kan's predecessor as premier quit last year after being accused of reneging on a promise to remove at least one of the bases.


I hope this disaster can be contained as soon as possible but what if they get hit by another large earthquake? The consequences do not even bear thinking about. It will affect us more than we think. Although the Pacific is a huge sea, there are the dangers of the food chain being affected a long way from the incident..

What a terrible situation. All this has happened because of stupid mistakes. The plants major back up power system, their diesel generators, weren't placed high enough above sea level to survive a tsunami. If these generators hadn't been flooded, they would have worked as planned and the plants would not have overheated.

I can't believe that the Japanese government would even consider building nuclear power plants in the first place. Their country experiences over 300 earthquakes a year. Such a foolish thing to do in my opinion.

Yes, nuclear power is very clean, but I don't think it's worth it when things like this happen.

Yes I totally agree Dash.Nuclear power is efficient but so difficult to deal with when it becomes unstable through either an earthquake or a malfunction at the plant.Before anymore Nuclear Power stations are built we all have to look very closely at the various scenarios which can occur through the life of the plant and try and discover how to deal with any unexpected disasters for the sake of our future generations and this fragile planet. icon_thumright.gif
