Japan:New decontamination plan for nuclear plant

The Japanese government and operator of the crippled Fukushima Daiichi nuclear power plant say they will try to reduce radioactive releases from the plant by directly treating contaminated gas in the reactors.

The government and TEPCO say the gas would be sucked from the reactors’ containment vessels through existing pipes, and then filtered to remove cesium and other radioactive substances.

The plan would be added to another project underway to fully cover the Number One reactor building with polyester sheets.

The Nuclear and Industrial Safety Agency says multiple measures are needed to reduce the radioactive substances being released from the plant.

The amount has decreased substantially since right after the accident, but the plant is still believed to be leaking radiation at a rate of about one billion becquerels per hour.

Some of the radioactivity is likely escaping from gaps created by explosions in the reactors’ containment vessels.

The government and TEPCO’s timetable aims for steep cuts in the release of radioactive material by January 2012.
