ENCLOSURE 3 Report Consistent with 10 CFR 54.37(b) 2 pages to follow ENCLOSURE 3 Report Consistent with 10 CFR 54.37(b) This summary report is in lieu of adding a level of detail to the Prairie Island Nuclear Generating Plant (PINGP) Updated Safety Evaluation Report (USAR) that is greater in the remainder of the USAR, including the License Renewal Supplement in Appendix L. The contents of this report are consistent with the requirements of 10 CFR 54.37(b) and the guidance of Regulatory lssye Summary (RIS) 2007-16, "Implementation of the Requirements of 10 CFR 54.37(b) for Holders of Renewed Licenses" (ADAMS Accession Number ML 100250279).

  • A review of engineering changes, equipment list changes, USAR changes, changes to equipment credited to 1 (:) CFR 54.4(aH3) regulated events, and changes to time limited aging analyses (TLAA) was conducted for the review period from December 5, 2015 to November 20, 2017. These changes were reviewed to identify components installed before June 27, 2011 that had not previously been screened or screened incorrectly for being in scope of License Renewal Aging Management.

From the review process, all but one newly identified component was found to already have been subject to existing Aging Management Programs (AMPs) in accordance with applicable aging management tables in PINGP's License Renewal Application (LRA). With the conclusion of this review, all aging effects requiring management are being managed to ensure License Renewal intended functions are effectively maintained throughout the period of extended operation.

  • The one "newly identified" component that did not fall into an existing category (component type/material/environment combination) in jts associated system (Fire Protection)

Table 3.3.2-9 in PINGP's LRA was 058-281 (122 DD FIRE PMP CLG WTR DISCH TO HX PRV STRNR). The impact on existing aging *management programs are discussed below. The table provided in the LRA is not actually being revised. However, the table below indicates the changes that would have been required to address this newly identified component in LRA 3.3.2-9. Aging Management discussion of filter/strainer 058-281: Bronze filter/strainer 058-281 is in the Fire Protection System. Its internal environment is raw water, and its external environment is plant indoor air -uncontrolled.

Since no bronze filter/strainer housings were listed in PINGP's License Renewal Application in the Fire Protection System (LRA Table 3.3.2-9), 058-281 was determined to be a newly identified SSC that would have been subject to an aging management review or evaluation of time-limited aging analysis in accordance.with 10 CFR 54.21. 10 CFR 54.37(b) states that the FSAR update IAW 10 CFR 50.71(e) must describe how the effects of aging will be managed such that the intended Page 1 of 2 Enclosure 3 NSPM function(s) in 10 CFR 54.4(b) will be effectively maintained during the period of extended operation.

In the case of 058-281, its internal surfaces aging effects will be managed by the Fire Water Aging Management Program. Bronze was found to be not susceptible to selective leaching during License Renewal implementation.

Therefore, 058-281 will not be added to the Selective Leaching of Materials AMP. Bronze Filter/Strainer Housings will be

  • added to PINGP's Fire Water Aging Management Program. Component Type If the actual LRA Table 3.3.2-9 were updated for the material and environment combinations of 058-281, the addition would look like the following table entry below.
