TEPCO confirms damage to part of No. 4 unit’s spent nuke fuel, Kyodo, April 13, 2011:
Some of the spent nuclear fuel rods stored in the No. 4 reactor building of the crisis-hit Fukushima Daiichi power plant were confirmed to be damaged, but most of them are believed to be in sound condition, plant operator Tokyo Electric Power Co. said Wednesday.
The firm known as TEPCO said its analysis of a 400-milliliter water sample taken Tuesday from the No. 4 unit’s spent nuclear fuel pool revealed the damage to some fuel rods in such a pool for the first time, as it detected higher-than-usual levels of radioactive iodine-131, cesium-134 and cesium-137.
The No. 4 reactor, halted for a regular inspection before last month’s earthquake and tsunami disaster, had all of its fuel rods stored in the pool for the maintenance work and the fuel was feared to have sustained damage from overheating.
The roof and the upper walls of the No. 4 reactor building have been blown away by a hydrogen explosion and damaged by fires since the disaster struck the plant. The water level in the spent fuel pool is believed to have temporarily dropped. …
