It's not the Christmas present that residents of northwestern Japan were hoping for.
The Asahi Shimbun newspaper reported today that Tokyo Electric Power Corp. has revealed that "225 tons of radioactive rainwater likely leaked from cracks in the barriers surrounding storage tanks at the crippled Fukushima No. 1 nuclear power plant".
It appears to be the largest leak from the tank barriers since a March 11, 2011, earthquake and tsunami devastated the facility.
The water has seeped into the soil, according to the newspaper.
The power company released the news on Christmas Eve.
