Water leak found at Fukushima Daiichi plant

Tokyo Electric Power Company has reported a radioactive water leak at the Fukushima Daiichi nuclear plant’s Number 4 reactor. The utility says a worker patrolling on Tuesday morning found water one-centimeter deep across a 350-square-meter room on the first floor of the turbine building. The water apparently comes from a pipe running along a corridor outside the room. The pipe carries contaminated water from the adjacent Number 3 reactor to a storage facility, according to Japan’s NHK world. Workers later detected radioactive cesium at about 77,000 becquerels per milliliter in the water. TEPCO said there is no evidence the water has escaped into the environment. Also on Tuesday morning, TEPCO workers found white smoke rising from a pump in a storeroom. The room houses equipment to filter radioactive substances from water. The workers used an extinguisher to put out the fire. The company is investigating the cause.
