Japan has restarted its controversial "fast-breeder" nuclear reactor, 14 years after the plant was shut down following a fire.

The Monju Prototype Fast Breeder Reactor, located in the coastal town of Tsuruga, was reactivated on Thursday for the first time since the cover-up of the accident in 1995.

Kazuo Mukai, the director-general of Monju, said that the nuclear reactor was reactivated after one of its control rods, which had been inserted to prevent an atomic reaction, was lifted.

The reactor is expected to reach criticality, the point when a nuclear chain reaction becomes self-sustaining, on Saturday but is not scheduled to generate power at full capacity until 2013.

Monju's relaunch was delayed for years in part because of outrage over the accident and the cover-up by the operator, which had initially released altered video footage of the fire in the facility.

The fire, which came only months after the plant had started generating electricity, was sparked after sodium coolant leaked from a pipe and reacted with oxygen and moisture.

Nuclear reliance

No one was injured and no radioactivity released, but safety inspections later found more problems at the plant, including a corrosion hole in a ventilation duct that would have leaked radioactive emissions outside the facility.

"We demand that the government stop playing Russian roulette with our lives and permanently close down Monju"

"I never thought it would take so long to restart Monju," Hiromi Tanabe, Japan's atomic energy agency adviser, said.

"We know by now how important it is to disclose information to the public."

Japan, the world's second largest economy, has few energy resources of its own and relies on the nuclear power generated by more than 50 plants for nearly one-third of its domestic electricity needs.

Opponents of nuclear power stress the risk of earthquakes in Japan, which is located at the intersection of four tectonic plates, dotted with volcanos and is regularly hit by strong tremors.

The Tokyo-based group the Citizens' Nuclear Information Centre said: "We believe that Monju is an accident waiting to happen and that it is, therefore, irresponsible to restart the plant."

The group said the during the plant's long closure its equipment and piping had aged and that two active seismic faults below the site had now been recognised.

"We demand that the government stop playing Russian roulette with our lives and permanently close down Monju," the group said.

In July 2007, the world's biggest nuclear plant, Kashiwazaki-Kariwa, northwest of Tokyo, was shut down by a strong tremor, although no one was hurt. Only two out of its seven reactors have resumed operations.
