This inspection plan is being submitted pursuant to Operating License Condition 2.C(15)(h) which requires that a long-term steam dryer inspection plan based on industry operating experience along with the baseline inspection results be submitted within 6 months following completion of the second refueling outage after the implementation of the EPU.
The inspection plan is in part based on WCAP-17635, Rev. 3 (Reference 1) which was submitted to the NRC in the Reference 2 letter and referenced by the NRC in the NRC Safety Evaluation Report for Extended Power Uprate (Reference 3).

Attachment Peach Bottom Unit 3 Long-Term Steam Dryer Inspection Plan at EPU Conditions Page 1of2 Purpose This document provides the long-term inspection plan for the Peach Bottom Unit 3 Replacement Steam Dryer (RSD) as required by the Renewed Facility Operating License No DPR-56, License Condition 2.C(15)(h). This license condition requires that the long-term inspection plan be submitted within 6 months following completion of the second refueling outage after the implementation of the EPU and be based on industry operating experience along with baseline inspection results.
RSD Long-Term Inspection Plan Input A long-term steam dryer inspection plan was developed for Peach Bottom Unit 3 following completion of the 2017 and 2019 refueling outages. These outages were the first and second refueling outages following implementation of EPU. The plan is based on WCAP-17635-P section 5.5, inspection results from the 2017 and 2019 outages, recommendations from Westinghouse, the RSD manufacturer, and recent industry Operating Experience (OE).
WCAP-17635-P This document was submitted to and reviewed by the NRC during the EPU licensing process. Section 5 provides the inspection plan for the first inspection and subsequent inspection following EPU implementation . The plan was implemented in the 2017 and 2019 outages. The inspection scope is based upon Operating Experience (OE) for the Westinghouse steam dryer design from previous installations, high cyclical stress locations determined from dryer acoustic analysis and finally, by higher stress locations where solution annealing of structural welds has not been performed . In addition, general principles and conclusions from BWRVIP-139 and RG 1.20 were applied to the inspection plan.
Furthermore, the document states that the RSD is octagonal (high symmetry) and inspections will be performed on limited sections of the octagon. For a typical weld ID, there are 8 locations, one on each of the 8 sections of the dryer. If flaws are identified, the comparable locations on the other seven sections of the dryer will be examined in the same outage.
Inspection Results for the 2017 and 2019 Outages Between the two outages, five indications were found at three general locations: two were associated with a fillet welds for the lifting rod interface to the support ring, two were associated with tacks welds for the lifting rod lug to lifting rod interface, and one was associated with a shim on a seismic block. Details on the results of the 2017 outage were provided in Reference 4, and details on the results of the 2019 outage were provided in Reference 5.
The fillet welds for the lifting rod interface to the support ring and the tacks welds for the lifting rod lug to lifting rod interface are non-structural and were not explicitly modeled or analyzed as part of the structural qualification of the steam dryer. A shim on a seismic block exhibited gouge marks on the vertical side of the block. The gouges were most likely caused by damage on the RPV steam dryer support brackets from a past event prior to installation of the RSD. All indications are acceptable for plant operations and will be periodically inspected .
Attachment Peach Bottom Unit 3 Long-Term Steam Dryer Inspection Plan at EPU Conditions Page 2 of 2 Westinghouse Recommendations To supplement the WCAP-17635-P inspection plan, Westinghouse recommended inspecting additional high stress locations and/or areas which should be inspected since some locations were not polished during fabrication . Some welds were inaccessible for polishing during the fabrication sequence and, due the lack of polishing, are more susceptible to IGSCC cracking than polished locations. The recommendations incorporated the latest stress analyses.
Recent Operating Experience Westinghouse was contacted regarding current operating experience of Westinghouse designed steam dryers. Since issuance of the WCAP in 2014, there has been no industry Operating Experience (OE) that changes Westinghouse inspection recommendations for Peach Bottom Unit 3. Also, inspection results of the Peach Bottom Unit 2 RSD had similar results as the unit 3 RSD. Therefore, no additional inspections are necessary due to recent OE.
Long-term RSD Inspection Plan The inspection plan includes inspection of the various locations over 10-year periods. This frequency is consistent with re-inspection frequency of BWRVIP-139 and Westinghouse recommendations. The RSD is octagonal (high symmetry) and inspections will be performed on limited sections of the octagon. For a typical weld ID, there are 8 locations, one on each of the 8 sections of the dryer. If flaws are identified, the comparable locations on the other seven sections of the dryer will be examined in the same outage.
Over the ten-year periods, the plan requires inspection of:
- One location per weld ID in accordance with WCAP-17635-P, section 5.5.
- One location per weld ID in accordance with Westinghouse recommendations.
- All flaws found during inspections (Re-inspections).
The inspection plan is a "living document," which will be modified as appropriate to incorporate lessons learned from other dryer inspections, particularly lessons learned from inspections on Westinghouse steam dryers.

Conclusion:==
A long-term inspection plan has been developed for the Peach Bottom Unit 3 Replaced Steam Dryer. Submittal of the plan satisfies the Peach Bottom Unit 3 Facility Operating License Condition 2.C(15)(h) for the Replacement Steam Dryer.
