Pacific Gas & Electrichas provided the US Nuclear Regulatory Commission (NRC) with a final report into the location of segments of a used nuclear fuel rod at its Humboldt Bay plant near Eureka in northern California.
The investigation began last June with the discovery of conflicting records on the location of three, 18-inch long cut segments which indicate the segments were either stored in the used fuel pool in 1968 or were shipped to a licensed nuclear waste facility in 1969.
The investigation indicates that the three segments have been found in the used fuel pool, but in broken, fragment form rather than as intact, 18-inch cut segments. However, after nearly 40 years of storage in a container within the used fuel pool under other irradiated material, conclusive positive identification is difficult.
