FUKUSHIMA – Tuesday’s magnitude 7.2 quake caused radioactive water to leak at three reactors in Fukushima Prefecture, Tokyo Electric Power Co. said Wednesday.
Tepco claimed the radioactivity level was low and the incidents did not affect the areas outside the facilities.
During the quake, water in pools to hold spent nuclear fuel washed into air ducts located about 10 cm above the surface, which led to 24.5 liters of radioactive liquid at the three reactors leaking through joints in the ducts and onto the floors of the buildings, it said.
The leaks were at the No. 2 and No. 6 reactors of the Fukushima No. 1 nuclear plant and the No. 4 reactor of the Fukushima No. 2 plant.
Trains still snarled
Service on the quake-hit Tohoku Shinkansen Line remained disrupted Wednesday, one day after being paralyzed by the strong earthquake in Miyagi Prefecture.
The first trains began running just after 6 a.m. as scheduled, but operations quickly became delayed, due in part to a breakdown at 6:15 a.m. at JR Oyama Station in Tochigi Prefecture in the computer system that controls departures, East Japan Railway Co. said.
Several trains were canceled and on some sections of the line, including from Fukushima Station to Shiroishizao Station in Miyagi Prefecture, trains ran at slower speeds.
The problems affected 113 trains and resulted in delays of up to 2 hours and 12 minutes, according to the railway.
About 64,000 passengers were affected, many of them returning home from the Bon holiday, it said.
