Japan switches off last reactor

A Japanese power company on Saturday began switching off the country's last working reactor, leaving it without any nuclear power just over a year after the worst nuclear accident in a quarter century.

This aerial view, taken in 2010, shows the Tomari nuclear plant in northernmost Hokkaido.

As technicians close down the No. 3 unit at Tomari in Hokkaido, the debate over whether Japan needs nuclear power has been reignited, amid increasingly shrill warnings of summer power blackouts.

Hokkaido Electric Power, which runs the plant, said it started inserting control rods at 5pm (3pm Thailand time) that would halt the chain reaction and bring the reactor to a "cold shutdown" some time on Monday.

"Power output has started declining at the No. 3 unit," said Tomohiko Shibuya, a Hokkaido Electric Power spokesman. "We have not heard of any trouble so far. Power generation there is scheduled to stop completely in about six hours."

The shutdown will mark the first time since the 1970s that resource-poor and energy-hungry Japan has been without nuclear power, which had provided a third of its electricity until meltdowns at Fukushima.

The tsunami-sparked disaster forced tens of thousands of people from their homes in an area around the plant -- some of whom may never be allowed to return.

It did not directly claim any lives, but has devastated the local economy, leaving swathes of land unfarmable as radiation spewed from the ruins.

With the four reactors at Fukushima crippled by the natural disaster public suspicion of nuclear power grew, so much so that no reactor shut for routine safety checks has since been allowed to restart.

"A new (era in) Japan with no nuclear power has begun," said Gyoshu Otsu, a 56-year-old monk who joined a protest against nuclear power in front of the industry ministry in Tokyo which supervises the nation's power utilities.

"Generating nuclear power is like a criminal act as a lot of people are still suffering," said Otsu wearing white Buddhist clothes. "If we allow the situation as it is now, another accident will occur."

Protest organiser Masao Kimura said: "It's a symbolic day today. Now we can prove that we will be able to live without nuclear power."

Separately, some 5,500 demonstrators staged a rally at a park near Tokyo Tower and later marched through central Tokyo carrying banners, which read: "Sayonara (Goodbye), nuclear power."

"We have to take action now so that Fukushima should be the last nuclear accident not only in Japan but all over the world," Mizuho Fukushima, head of the opposition Social Democratic Party, told AFP during the rally.

When generation stops late Saturday, Japan's entire stable of 50 reactors will be offline, despite increasingly urgent calls from the power industry and bodies like the OECD, who fear dire consequences for the world's third largest economy.

Last month, Kansai Electric Power, which supplies mid-western Japan, including the commercial hubs of Osaka, Kyoto and Kobe, said a hot summer could see supply fall nearly 20 percent short of demand.

Kyushu Electric Power, covering an area farther west, as well as Hokkaido Electric Power also said they would struggle as air conditioning gets cranked up in Japan's sweltering summer.

Kansai Electric last month booked a $3-billion annual loss, turning around a $1.5-billion profit the year earlier on the increased cost of using previously mothballed thermal fuel plants.

A week earlier, Prime Minister Yoshihiko Noda's government gave the green light to restarting reactors at the Oi nuclear plant, run by Kansai Electric, but regulators still have to convince those living near the plant.

In order to be fired up again, reactors must now pass International Atomic Energy Agency-approved stress tests and get the consent of their host communities. This last hurdle is proving hardest to overcome.

Critics of nuclear power say Japan has managed thus far with its ever dwindling pool of reactors and need not look back.

The environmental campaign group Greenpeace said Friday that the country should concentrate on ramping up renewables and boosting energy efficiency.

"Despite the closure of all reactors, security of electricity supply is not threatened in Japan," said Hisayo Takada, a climate and energy campaigner with Greenpeace Japan.
