Japan:Troubled reactors all cool below 100 degrees + Related Articles

The temperature of reactor Number 2 at the Fukushima Daiichi nuclear power plant remains below 100 degrees Celsius, leaving the mercury below the 100-mark at all 3 troubled reactors.

The reading in the lower area of the reactor was 99.4 degrees at 5 PM Wednesday, falling below 100 degrees for the first time since the March nuclear crisis.

The temperature in the same area stood at 99.7 degrees at 11 AM Thursday, after rising slightly above 100 degrees between Wednesday night and early Thursday morning.

Tokyo Electric Power Company or TEPCO stepped up cooling efforts to control the Number 2 reactor, where temperatures remained at the mid-110 degree mark until earlier this month.

Temperatures at the Number 1 and 3 reactors have been maintained below 100 degrees since August, after the mercury shot up to nearly 400 degrees in late March at reactor Number 1.

TEPCO says it’s too early to say if it has attained a state of cold shutdown, meaning that temperatures at all 3 reactors are kept stable and below 100 degrees.

The utility says it’s now vital to ensure a reliable cooling system to achieve cold shutdown.


Facilites to store contaminated soil to be built


The environment ministry says it will build facilities to temporarily store radioactive contaminated soil in Tokyo and 7 prefectures in eastern and northern Japan.

Vice environment minister Hideki Minamikawa told reporters about the plan in Koriyama City, Fukushima Prefecture, on Wednesday.

Local governments have been trying to remove radioactive materials since the crisis began at the Fukushima Daiichi nuclear plant. But they are struggling to find places to store mud and sludge generated by the decontamination.

Minamikawa said the storage facilities are needed to make progress in removing radioactive substances.

He said local governments other than Fukushima should have their own storage places.

According to the plan, the facilities will be built in Tokyo and 4 other prefectures in Kanto and 3 prefectures in the Tohoku region.

The ministry says it will soon explain the plan to each local government.
