The Indian Point Units 2 and 3 small and large break analyses were reviewed by the NRC as part of the Indian Point Units 2 and 3 stretch uprate projects. There were no additional changes to the aforementioned analyses in 2005.

The Indian Point Units 2 and 3 PCTs remain below the maximum fuel clad temperature of 22000 F.
