Request for Additional Information (RAI) 4.3.1-1 The Prairie Island Nuclear Generating Plant (PINGP) metal fatigue of reactor coolant pressure boundary management program relies on transient cycle monitoring to evaluate the fatigue usage described in the license renewal application. This approach tracks the number of occurrences of significant thermal and pressure transients (significant events) and compares the cumulative cycles, projected to cover the renewal period, against the number of design cycles specified in the design specifications. The projected cycles are then used to evaluate the total cumulative usage factor (CUF) which covers the period of extended operation. For this approach to work, none of the significant events tracked should produce stresses greater than those that would be produced by the design transients. That is, the P-T (Pressure and Temperature) characteristics, including their values, ranges, and rates, all must be bounded within those defined in the design specifications.
(a) Please describe the procedures that PINGP has been using for tracking thermal activities so the staff can confirm that the PINGP aging management program will ensure that P-T characteristics, including their values, ranges, and rates remain bounded within the range defined in the design specifications during the renewed license term.
(b) Please provide a histogram (cycle accumulating charts) of heatup transient history, and a histogram for the cooldown transient as well.
RAI 3.3.2.9-2 In License Renewal Application (LRA) Table 3.3.2-9, page 3.3-198, 199 and 200, fire protection system, for copper alloy heat exchanger components and heat exchanger tubes in an internal environment of raw water, PINGP has credited the Fire Water System Program to manage the aging effects loss of material and heat transfer degradation. These lines reference footnote E, and NUREG-1801, Generic Aging Lessons Learned (GALL) Report, Revision 1, item VII.C1-3.
The GALL Report item recommends AMP XI.M20, Open-Cycle Cooling Water Program to manage these aging effects for heat exchangers. The GALL AMP recommends chemical treatment whenever the potential for biofouling species exists as part of the preventive actions and a test program to verify heat transfer capabilities.
Please justify why Open-Cycle Cooling Water System Program is not used.
