The operator of the crippled Fukushima Daiichi nuclear power plant succeeded Friday in taking a sample of water from the No. 1 reactor’s primary containment vessel, the first such attempt since the accident at the plant occurred last year.
Considering the water’s radiation level and other data, Tokyo Electric Power Co. said the fuel, which is believed to have melted through the pressure vessel and accumulated in the outer primary container, does not appear to be releasing large amounts of radioactive substances because it is kept cool.
The water contained 19,000 becquerels of cesium 134 per cubic centimeter and 35,000 becquerels of cesium 137, lower than the density levels of the water accumulating at the building housing the reactor.
