Village invited to test cheap, clean nuclear power

A Japanese corporation wants to thrust the Interior community of Galena into international limelight by donating a new, unconventional electricity-generating plant that would light and heat the Yukon River village pollution-free for 30 years.

There's a catch, of course. It's a nuclear reactor.

Not a huge, Three Mile Island-type power plant but a new generation of small nuclear reactor about the size of a big spruce tree. Designers say the technology is safe, simple and cheap enough to replace diesel-fired generators as the primary energy source for villages across rural Alaska.

Such a plant would also have enough excess power to create hydrogen gas, proponents say. They envision Galena as a demonstration center for the highly vaunted hydrogen economy, in which cars and trucks could run on the clean-burning gas....


...The reactor has almost no moving parts and doesn't need an operator. The nuclear reaction is controlled by a reflector that slowly slides over the uranium core and keeps the nuclear fission "critical." If the reflector stops moving, the reactor loses power. If the shield moves too fast, the core "burns" more quickly, yielding the same amount of power but reducing the reactor's life, Rosinski said.

Because of its design and small size, the Toshiba reactor can't overheat or melt down, he said, unlike what happened in the 1986 accident at Chernobyl that killed 30 people and spewed radiation across northern Europe....
