aug 16, 1960 - Large amounts of the boron strips were missing from some fuel elements and the fuel elements in the center of the core were extremely difficult to remove by hand. (Large loss of Boron attributed to larger rate of gain of reactivity)
Description:
Removal caused plates to fall off and flaking of material. A considerable number of flakes were collected from the bottom of the vessel. As a result of these circumstances, it was felt that further removal of fuel elements might cause further loss of boron, so that no further inspections were conducted.
