SUMMARY
OF AUGUST 4, 2023, U.S. NUCLEAR REGULATORY COMMISSION PUBLIC OBSERVATION MEETING WITH THE PRESSURIZED WATER REACTOR OWNERS GROUP TO DISCUSS CLARIFICATION OF REQUESTS FOR ADDITIONAL INFORMATION ON TOPICAL REPORT PWROG-18068-NP, REVISION 1 (EPID L-2021-TOP-0027)
On August 4, 2023, the U.S. Nuclear Regulatory Commission (NRC) staff held a public meeting with the Pressurized Water Reactor Owners Group (PWROG) to provide clarification on Request for Additional Information (RAI) questions regarding Topical Report (TR)
PWROG-18068-NP, Revision 1, Use of Direct Fracture Toughness for Evaluation of Reactor Pressure Vessel Integrity (Agencywide Documents Access and Management System ADAMS Accession No. ML21209A933) transmitted for NRC review and approval on July 17, 2021. The meeting was held virtually and provided the opportunity to discuss PWROGs proposed responses to NRCs RAI questions in an open and collaborative environment. The meeting notice and presentation slides are publicly available at ADAMS Package Accession No. ML23209A041. A list of the meeting attendees is enclosed in this meeting summary.
TR PWROG-18068 provides an alternative methodology to the Reactor Pressure Vessel material integrity requirements which are available in Title 10 of the Code of Federal Regulations Appendix G to Part 50, Fracture Toughness Requirements, Section 50.60, Acceptance criteria for fracture prevention measures for lightwater nuclear power reactors for normal operation, and Section 50.61, Fracture toughness requirements for protection against pressurized thermal shock events. As a result of the technical review of TR PWROG-18068, Rev. 1, the NRC staff transmitted RAI questions and PWROG provided the proposed responses to the RAIs. During the August 4, 2023, public observation meeting, the NRC staff provided clarification on the first half of PWROGs draft responses up to RAI 13, but due to the meeting time constraint no additional draft RAI responses were discussed. The entire draft RAI response markup is available at ADAMS Accession No. ML23180A161.
CONTACT: Leslie Fields, NRR/DORL 301-415-1186
Subsequently, to complete the discussion on the second half of the PWROGs draft responses, it was determined that Part 2 of this public meeting would be scheduled in the near future. All information regarding the future meeting will be posted on NRCs Public Meeting Notification System.
At the conclusion of the meeting, there was an opportunity for the public to provide comments and ask questions. It was noted that no public comments were received.
Please direct any inquiries to me at (301) 415-1186 or by e-mail at Leslie.Fields@nrc.gov.
