FUEL ELEMENT DROP

A fuel element from F-ring, during routine inspection, was dropped at 12.00 on 30 July 1992 from a height of about 4.25 metres under water to the bottom of the reactor tank. The incident was duly reported to the national nuclear safety committee and was subsequently investigated. Neither any radioactive release to the atmosphere nor any contamination in the tank water was detected. Both the tank bottom and the fuel element appeared to be ok. Operation was restored with a new fuel element in the vacant location. The dropped fuel element is kept in the fuel storage rack inside the pool for closer inspections at a later date. Procedural mistakes appeared to be the most probable cause. Appropriate measures were suggested to avoid repetitions.
