Title: Bent rod found at TEPCO’s Niigata reactor
Source: THE ASAHI SHIMBUN
Date: December 13, 2012

Tokyo Electric Power Co. said Dec. 12 a bent water rod caused two fuel rods to come into contact inside a fuel rod assembly stored in a spent fuel storage pool for the No. 5 reactor of the Kashiwazaki-Kariwa nuclear power plant in Niigata Prefecture.

No damage to nuclear fuel or other anomalies have been reported, but the two fuel rods may have been in contact with each other when they were burning inside the reactor.

The situation had the potential to cause a serious fuel failure accident. [...]

Water rods [a passage for coolant water that runs through the center of a fuel assembly] were found to be bending in 18 fuel rod assemblies in the storage pool. Closer studies found that in one fuel rod assembly, the bending water rod pushed one nearby fuel rod into contact with another. [...]
