The License Renewal Application (LRA) for DCPP Units 1 and 2 was submitted on 11/23/09, DCL-09-079.

Procedure MA1.ID20, Testing/Inspections for Aux Saltwater System NRC Generic Letter 89-13 Compliance, Rev. 2, Section 5.7.7.a, states that "Although there is no commitment to test, CCW heat exchangers are part of GL 89-13: it is considered prudent to monitor heat transfer performance."

LRA Section B2.1.9, Open-Cycle Cooling Water System, states that DCPP performs periodic testing of the CCW heat exchangers prior to each refueling outage to verify their heat transfer capability.

Procedure MA1.ID20, Section 5.7.7.a, needs to be revised.
