The Japanese government and Tokyo Electric Power Company will announce on Tuesday a revised plan to bring the reactors at the Fukushima Daiichi nuclear power plant under control.

They are expected to say that the first stage of the plan has been almost completed on schedule.

But a system to decontaminate radioactive water, which began operating at the end of last month, is working below the target capacity due to leaks and other problems.

The system’s decontamination rate dropped to 37 tons of water per hour at one point, more than 20 percent below the target capacity.

It increased to 39 tons per hour after TEPCO workers released air from the pipes on Friday. They also replaced a hose connecting the tanks to ease water circulation.

However, the rate dropped again to 37 tons per hour on Monday morning. TEPCO says the reason for the decrease is unknown.
