The power outage that affected the spent nuclear fuel pools at the Fukushima-Daiichi nuclear plant earlier this week was apparently caused by a rat, according to TEPCO officials quoted by Agence-France Presse.
As of Wednesday, power had been fully restored to all fuel cooling pools at the facility.
TEPCO released an image of the rodent carcass found near the damaged switchboard unit that caused led to the surprise outage. Burn marks were found on the switchboard, which was apparently short circuited by the rat.
