Fukushima cooling systems fail for second time in a month

The cooling system at Japanese nuclear firm Tepco’s Fukushima nuclear plant has lost power for the second time in less than a month.

The cooling system was triggered at 2.27pm local time today, indicating that the cooling system had stopped working. The cause of the leak is being investigated

The system is expected to be up and running before the end of the day, the firm said. Water temperature was 15.1°C at 2pm local time and rising at a rate of 0.145°C per hour. If left unfixed the water would not reach the safety limit is 65C for two weeks.

On 19 March a power failure at the plant caused three cooling systems to stop working. An investigation concluded that the power failure had been caused by a rat damaging the electrics.
