SUMMARY
OF TELEPHONE CONFERENCE CALL HELD ON SEPTEMBER 21, 2011, BElWEEN THE U.S. NUCLEAR REGULATORY COMMISSION AND NEXTERA ENERGY SEABROOK, LLC, CONCERNING CLARIFICATION OF INFORMATION PERTAINING TO THE SEABROOK STATION LICENSE RENEWAL APPLICATION (TAC NO. ME4028)
The U.S. Nuclear Regulatory Commission (NRC or the staff) and representatives of NextEra Energy Seabrook, LLC (NextEra or the applicant), held a telephone conference call on September 21, 2011, to obtain clarification on information contained in the Seabrook Station license renewal application (LRA). The telephone conference call was useful in clarifying the applicant's information in the LRA. provides a listing of the participants and Enclosure 2 contains a summary of the issues discussed during the call with the applicant.
The applicant had an opportunity to comment on this summary.

TELEPHONE CONFERENCE CALL SEABROOK STATION LICENSE RENEWAL APPLICATION Draft Follow~up RAI In response to request for additional information (RAJ) 3.1.1-60~2, by letter dated February 3, 2011, on page 9 of 92, the applicant stated, "The flux thimble tube no longer provides a function of pressure boundary hence, it has no license renewal function, and it will be removed from scope."
In response to follow-up RAI 3.1.1-60-01102, by letter dated April 22, 2011, on page 6 of 43, the applicant stated, "When the incore detector assembly is inserted, the thimble housing tube (outer tube) provides the reactor coolant system (RCS) pressure boundary to keep the incore detector assembly internal volume dry." The letter further stated that, "The thimble calibration tube (inner tube), although considered a RCS pressure boundary, is not in contact with reactor coolant."
Following the August 3,2011, teleconference discussion on the above topic, the staff still seeks clarification as to where exactly the applicant is taking credit for the RCS pressure boundary for the incore detector assemblies in the applicant's license renewal application and how it is dispositioned under 10 CFR 54.
Response
NextEra provided clarification of the thimble tube design configuration, provided a description of the RCS pressure boundary, and described the associated aging management programs.
NextEra agreed to provide this detailed information in a subsequent RAI response.
Follow-up Draft RAI 4.3.1-c
Background:
By letter dated April 22, 2011, the applicant responded to RAI 4.3-1 b stating that the pressure boundary portion of the ASME Class 1 valves were designed, analyzed, and qualified for service (including fatigue) in accordance with the rules of American Society of Mechanical Engineers (ASME) Code Section III Subsection NB-3500. Updated Final Safety Analysis Report (UFSAR) Table 5.2-1 identifies the code edition and addenda applicable to the design of the following types of Class 1 valves: pressurizer safety valves, motor-operated valves, manual valves, control valves, and pressurizer spray valves in the reactor coolant systems. UFSAR Table 5.2-10 also identifies the valves that are included in the reactor coolant pressure boundary.
Issue:
The staff noted that, in the 1971 and later editions of the ASME Section III Code, paragraphs NB-3545.3 and NB-3550 required fatigue analyses for valves that have an inlet piping connection larger than 4 inches nominal pipe size unless the exemption reqUirements of ENCLOSURE 2
2 NB-3222.4(d) are met. The staff also noted that the 1968 Draft ASME Pump and Valve Code Sections 452 and 454 included applicable time-dependent cyclic or fatigue assessment criteria to be performed jf the inlet piping connection is larger than 4 inches nominal pipe size. It is not clear to the staff if the fatigue analyses for these Class 1 valves were performed in accordance with the requirements of the applicable ASME codes.
Request:
- Identify all the Class 1 valves that did not have a fatigue analysis performed as part of the design-basis and their associated design code. In addition, justify why a fatigue analysis was not required for these Class 1 valves in accordance with the ASME Section III Code or the ASME Draft Pump and Valve Code, with reference to the applicable sections of the design code.
- If a fatigue analysis was performed as part of the design-basis for Class 1 valves, justify the conclusion that the fatigue analyses for these Class 1 valves do not need to be identified as a time-limited aging analysis in accordance with 10 CFR 54.21(c)(1).
Response
