The operator of the damaged Fukushima Daiichi nuclear power plant has issued a schedule for putting the crisis under control in 6 to 9 months.

The chairman of Tokyo Electric Power Company, Tsunehisa Katsumata, explained the plan at a news conference on Sunday.

The utility firm said a two-phase process is scheduled.
In the first stage over the next 3 months, it will build new cooling systems outside the Number 1 and 3 reactor buildings to cool down the nuclear fuel, and to ensure that radiation levels around the plant continue to decline.

The company says it will contain the radioactivity leakage from the Number 2 reactor by patching the damaged section.

In the second stage, TEPCO plans to lower the temperature of the nuclear fuel in the reactors to below 100 degrees Celsius to stabilize its condition.

The firm says the cooling will considerably lower the radiation levels in the environment around the plant.

The two-phases will be completed in 6 to 9 months.

The firm also plans to cover the reactor buildings with giant covers with filters to prevent the release of radioactive substances into the air.

It will also set up equipment to purify the contaminated water in tanks and other facilities.

At the same time, the company will increase the number of monitoring points within the government-set evacuation areas. It will use the data to neutralize the radioactive substances in soil and on buildings.
