For two hours on Friday, for the second time in a month, the power for the cooling system at the crippled Fukushima Nuclear Power Plant in Japan failed in reactor No. 3. Last time a dead rat was found in the wiring. This time the act of putting up nets, to keep the rats and other animals out, was given as the cause.

Fukushima Blackout Linked to a Rat in the Wiring

During the power outage, the temperature inside the storage pool attached to reactor 3 was at about 15.1 degrees Celsius (59.18 Fahrenheit), indicating that the spent fuel cooling in the pool remained stable and was not posing immediate danger to the environment, reported the AFP.

“The cooling system can be turned off for two weeks before temperatures approach dangerous levels at the spent fuel storage pools. But if the water runs dry, the fuel rods, even spent ones, will spew enormous levels of radiation,” reported the USA Today.
