June 10, 2022 Mr. Cleveland Reasoner Chief Executive Officer and Chief Nuclear Officer Wolf Creek Nuclear Operating Corporation P.O. Box 411 Burlington, KS 66839
SUBJECT:
WOLF CREEK GENERATING STATION, UNIT 1 - WITHDRAWAL OF REQUESTED LICENSING ACTION RE: REQUEST I4R-08 FOR THE FOURTH INSERVICE INSPECTION PROGRAM INTERVAL, RELIEF FOR EXTENSION OF FOLLOW-UP EXAMINATION AND VISUAL EXAMINATION REQUIREMENTS FOR REACTOR PRESSURE VESSEL HEAD PENETRATION NOZZLES WITH MITIGATED ALLOY 600/82/182 PEENED SURFACE (EPID L-2022-LLR-0039)
Dear Mr. Reasoner:
By letter dated April 4, 2022 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML22095A252), Wolf Creek Nuclear Operating Corporation (the licensee) submitted a proposed alternative to the requirements regarding the follow-up volumetric examination frequency and bare metal visual examination requirements for the reactor pressure vessel head penetration nozzles at the Wolf Creek Generating Station, Unit 1.
The U.S. Nuclear Regulatory Commission (NRC) staff has been performing an acceptance review of the application. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant. By letter dated May 18, 2022 (ML22119A217), the NRC staff identified insufficient technical basis information in the application to begin its technical review.
Pursuant to Sections 50.55a(z)(1) and 50.55a(z)(2) of Title 10 of the Code of Federal Regulations (10 CFR), the applicant shall demonstrate that the proposed alternatives would provide an acceptable level of quality and safety, or that compliance with the specified requirements of Section 50.55a would result in hardship or unusual difficulty without a compensating increase in the level of quality or safety.
By [[letter::ET 22-0011, Withdrawal of 10 CFR 50.55a Request I4R-08, Relief for Extension of Follow-up Examination and Visual Examination Requirements for Reactor Pressure Vessel Head Penetration Nozzles with Mitigated Alloy 600/82/182 Peened Surface|letter dated May 31, 2022]] (ML22152A019), the licensee requested to withdraw the application from NRC review. The licensee plans to modify its request and resubmit. The NRC acknowledges the licensees request to withdraw the application. The NRC staff activities on the review have ceased and EPID L-2022-LLR-0039 is closed.
The NRC staff notes that its review to date has identified an insufficient technical basis for the licensees request. Therefore, should the licensee decide to resubmit the request, it should include the information described in the NRC staffs May 18, 2022, letter.
If you have any questions, please contact me at 301-415-3168 or via email at Samson.Lee@nrc.gov.
Sincerely,
/RA/
