By letter dated May 15, 2018 (Agencywide Documents Access and Management System (ADAMS) Package Accession No. ML18143B465), the Pressurized Water Reactor Owners Group (PWROG) submitted Topical Report (TR) PWROG-17011-NP, Revision 1, "Update for Subsequent License Renewal: WCAP-14535A, "Topical Report on Reactor Coolant Pump Flywheel Inspection Elimination" (and WCAP-15666-A, "Extension of Reactor Coolant Pump Motor Flywheel Examination,") to the U.S. Nuclear Regulatory Commission (NRC) staff for review. | |||

SUBJECT:
DRAFT SAFETY EVALUATION FOR PRESSURIZED WATER REACTOR OWNERS GROUP TOPICAL REPORT PWROG-17011-NP, REVISION 1 REPORT, UPDATE FOR SUBSEQUENT LICENSE RENEWAL:
WCAP-14535A, TOPICAL REPORT ON REACTOR COOLANT PUMP FLYWHEEL INSPECTION ELIMINATION AND WCAP-15666-A, EXTENSION OF REACTOR COOLANT PUMP MOTOR FLYWHEEL EXAMINATION (EPID: L-2018-TOP-0019)
Dear Mr. Nowinowski:
By letter dated May 15, 2018 (Agencywide Documents Access and Management System (ADAMS) Package Accession No. ML18143B465), the Pressurized Water Reactor Owners Group (PWROG) submitted Topical Report (TR) PWROG-17011-NP, Revision 1, "Update for Subsequent License Renewal: WCAP-14535A, "Topical Report on Reactor Coolant Pump Flywheel Inspection Elimination" (and WCAP-15666-A, "Extension of Reactor Coolant Pump Motor Flywheel Examination,") to the U.S. Nuclear Regulatory Commission (NRC) staff for review.
The NRC staff review determined that the information provided in the TR provides the technical and regulatory basis for continuing the 20-year in service inspection interval approved for reactor coolant pump motor flywheels for the period of extended operation (60 years) in WCAP-15666-A (ADAMS Accession No. ML18303A413), to the subsequent period of extended operation (80 years). The NRC staff has reviewed PWROG-17011-NP, Revision 1 and concludes that the subject report, as modified by the conditions and limitations summarized in Section 4.0 of the enclosed safety evaluation (SE), provides an acceptable methodology that can be used to support such a request.
Twenty working days are provided for you to comment on any factual errors or clarity concerns contained in the SE. The final SE will be issued and will be made publicly available after making any necessary changes. The NRC staff's disposition of your comments on the draft SE will be discussed in the final SE.
W. Anthony Nowinowski To facilitate the NRC staff's review of your comments, please provide a marked-up copy of the revised draft SE showing proposed changes and provide a summary table of the proposed changes.
If you have any questions, please contact Jason Drake at 301-415-8378.
