SUMMARY

OF MARCH 14, 2011, MEETING WITH EXELON TO DISCUSS PROPOSED MAIN STEAM SAFETY VALVE LICENSE AMENDMENT REQUEST (TAC NO. ME4808)

On March 14, 2011 t a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of Exelon Generation Company, LLC (Exelon, the licensee). The purpose of the meeting was to discuss Exelon's license amendment request (LAR) regarding proposed revisions to Main Steam Safety Valve (MSSV) Technical Specification (TS) 3.4.1.2.3. Exelon's vendor supporting the LAR, AREVA NP Inc., was also represented. The proposed changes would allow up to two MSSVs per steam generator to be inoperable with no required reduction in power level and would also revise the maximum overpower trip setpoints for any additional inoperable MSSVs.

Prior to the meeting, the NRC staff had developed a draft Request for Additional Information (RAI) which provided a framework for the meeting's discussion. This draft RAI can be found at Agencywide Documents Access and Management System Accession No. ML110620027.

During the meeting, the NRC staff and the licensee discussed the issues of concern. Based on the discussion, the NRC staff agreed to modify some of the questions to ensure that the information requested, as reflected in the RAI, is clearly communicated to the licensee. The NRC staff will issue the revised RAI to the licensee, by letter, at a later date.

No proprietary information was discussed at the meeting and no members of the public were present. A list of attendees is enclosed.

Please direct any inquiries to me at 301-415-2833 or peter.bamford@nrc.gov.
