Berrick, Salem Commitment Tracking Coordinator LR-N11-0151 Response to Draft Request for Additional Information Regarding Proposed License Amendment - Snubber Surveillance Requirements Salem Nuclear Generating Station - Units 1 and 2 NRC Docket Nos. 50-272 and 50-311 By letter dated October 4, 2010, as supplemented on April 7, 2011 (Agencywide Documents Access and Management System (ADAMS) Accession Nos. ML102780066 and ML110980107, respectively), PSEG Nuclear LLC (PSEG or the licensee) submitted an amendment request for Salem Nuclear Generating Station (Salem), Unit Nos. 1 and 2. The proposed amendment would revise the Technical Specification (TS) requirements for snubbers to conform to planned revisions to the inservice inspection (lSI) program.
The Nuclear Regulatory Commission (NRC) staff has reviewed the information the licensee provided that supports the proposed amendment and would like to discuss the following issues to clarify the submittal.
- 1.
Based on previous discussions with the NRC staff and in response to the NRC staff's draft RAI dated February 7,2011 (ADAMS Accession No. ML110390175), the licensee, in its letter dated April 7, 2011, proposed to add new TS 6.8.4.m, "Snubber Testing Program," to the Administrative Controls section of the TSs. Paragraph iv in TS 6.8.4.m would read as follows:
The 120-month program updates shall be made in accordance with 10 CFR 50.55a(g)(4), 10 CFR 50.55a(g)(3)(v) and 10 CFR 50.55a(b) (including 10 CFR 50.55a(b)(3)(v)) subject to the limitations and modifications listed therein.
Since snubbers are subject to both inservice testing as well as lSI, the program update provisions in 10 CFR 50.55a(f) and 10 CFR 50.55a(g) are applicable. As such, the NRC staff suggests that the above paragraph be revised to read as follows:
The 120-month program updates shall be made in accordance with 10 CFR 50.55a (including 10 CFR 50.55a(b)(3)(v)) subject to the limitations and modifications listed therein.
Response
PSEG proposes to revise paragraph iv in new TS 6.8.4.m as suggested above. The revised TS 6.8.4.m is provided below:
6.B.4.m Snubber Testing Program This program conforms to the examination, testing and service life monitoring for dynamic restraints (snubbers) in accordance with 10 CFR 50.55a in service inspection (lSI) requirements for supports. The program shall be in accordance with the following:
(i)
This program shall meet 10 CFR 50. 55a(g) lSI requirements for supports.
(ii)
The program shall meet the requirements for lSI of supports set forth in subsequent editions of the Code of LR-N11-01S1 Record and addenda of the American Society of Mechanical Engineers (ASME) Boiler and Pressure (BPV)
Code and the ASME Code for Operation and Maintenance of Nuclear Power Plants (OM Code) that are incorporated by reference in 10 CFR 50.55a(b) subject to limitations and modifications listed in 10 CFR 50.55a(b) and subject to Commission approval.
(iiij The program shall, as allowed by 10 CFR 50.55a(b)(3)(v),
meet Subsection ISTA, "General Requirements" and Subsection ISTD, "Pre service and In service Examination and Testing of Dynamic Restraints (Snubbers) in Ught-Water Reactor Nuclear Power Plants" in lieu of Section XI of the ASME BPV Code lSI requirements for snubbers, or meet authorized alternatives pursuant to 10 CFR
- 50. 55a(a)(3).
(iv)
The 120-month program updates shall be made in accordance with 10 CFR 50.55a (including 10 CFR 50.55a(b)(3)(v)) subject to the limitations and modifications listed therein.
All other proposed TS changes are as stated in PSEG's letter dated April 7, 2011.
