SUBJECT:
WOLF CREEK GENERATING STATION, UNIT 1 - WITHDRAWAL OF TITLE 10 OF THE CODE OF FEDERAL REGULATIONS SECTION 50.55a REQUEST I4R-09 FOR THE FOURTH INSERVICE INSPECTION PROGRAM INTERVAL, RELIEF FROM EXAMINATION OF REACTOR VESSEL FLANGE THREADS (EPID L-2022-LLR-0043)
Dear Mr. Reasoner:
By letter dated April 6, 2022 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML22097A302), Wolf Creek Nuclear Operating Corporation (the licensee) submitted an application requesting U.S. Nuclear Regulatory Commission (NRC) approval of Title 10 of the Code of Federal Regulations Section 50.55a, Request I4R-09 for the fourth 10-year inservice inspection program interval. Specifically, the licensee requested an alternative to the requirement to perform ultrasonic examinations of threads in reactor pressure vessel closure flange connections at the Wolf Creek Generating Station, Unit 1, on the basis that the proposed alternative provides an acceptable level of quality and safety.
By letter dated May 12, 2022 (ML22132A043), the licensee requested to withdraw the application from NRC review. The licensee plans to evaluate the use of American Society of Mechanical Engineers Code Case N-864, Reactor Vessel Threads in Flange Examinations,Section XI, Division 1, which was approved recently by the NRC. The NRC acknowledges the licensees request to withdraw the application. The NRC staffs review has ceased and EPID-L-2022-LLR-0043 is closed.
If you have any questions, please contact me at 301-415-3168 or via email at Samson.Lee@nrc.gov.
Sincerely,
/RA/
