OYSTER CREEK 6-23 Amendment No. ~. 286

UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 286 TO RENEWED FACILITY OPERATING LICENSE NO. DPR-16 EXELON GENERATION COMPANY, LLC OYSTER CREEK NUCLEAR GENERATING STATION DOCKET NO. 50-219

1.0 INTRODUCTION

By letter dated April 30, 2014 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML14127A435), as supplemented by letter dated October 16, 2014 (ADAMS Accession No. ML14294A056), Exelon Generation Company, LLC (Exelon or the licensee) requested changes to the technical specifications (TSs) for Oyster Creek Nuclear Generating Station (Oyster Creek or OCNGS). Specifically, the licensee requested to revise TS 4.5.M, "Shock Suppressors (Snubbers)," to delete detailed snubber inservice inspection (ISi) and testing requirements, and add Administrative Control TS 6.25, "Snubber Inspection Program," which includes the planned revisions to the OCNGS snubber ISi, testing, and service life monitoring programs.

• The fifth 10-year ISi interval at OCNGS began on January 15, 2013, and is scheduled to end January 14, 2023. Currently, snubber examination and testing are performed in accordance with the specific requirements of TS 4.5.M and the OCNGS plant procedures. For the remainder of the fifth 10-year ISi interval at OCNGS, the snubber program will meet the requirements of the American Society of Mechanical Engineers Code for Operation and Maintenance of Nuclear Power Plants (ASME OM Code), Subsection ISTD, Edition 2004 with 2005 and 2006 Addenda per Title 10 of the Code of Federal Regulations (10 CFR), Section::;,

50.55a(b)(3)(v).

The supplemental letter dated October 16, 2014, provided additional information that clarified the application, did not expand the scope of the application as originally noticed, and did not change the U.S. Nuclear Regulatory Commission (NRC) staff's original proposed no significant hazards consideration determination as published in the Federal Register on July 8, 2014 (79 FR 38590).

2.0 REGULATORY EVALUATION

A dynamic restraint (snubber) is a device designed to protect components from excess shock or sway caused by seismic disturbances or other transient forces. During normal operating conditions, the snubber allows for movement in tension and compression. When an impulse

event occurs, the snubber becomes activated and acts as a restraint device. The device becomes rigid, absorbs the dynamic energy, and transfers it to the supporting structure. The proposed change, in essence, relocates the specific snubber inservice examination and testing requirements located in TS 4.5.M, and replaces them with a new TS surveillance requirement 4.5.M.1 that requires "[e]ach snubber shall be demonstrated OPERABLE by performance of the Snubber Inspection Program." The Snubber Inspection Program is added in newly added Administrative Control TS Section 6.25, "Snubber Inspection Program."

The revised Snubber Inspection Program includes revisions to the OCNGS snubber ISi, testing, and service life monitoring programs. The purpose of the Snubber lnservice Program, as provided in the letter dated April 30, 2014, and as supplemented by letter dated October 16, 2014, is to provide requirements for the performance and administration of assessing the operational readiness of those dynamic restraints, whose specific functions are required to ensure the integrity of the reactor coolant pressure boundary.

The regulations in 10 CFR 50.36, "Technical Specifications," provide the regulatory requirements for the contents in a licensee's TSs. This regulation requires that the TSs include items in the following five specific categories related to station operation. These categories include: ( 1) safety limits, limiting safety system settings, and limiting control settings; (2) limiting conditions for operation (LCO); (3) surveillance requirements (SRs); (4) design features; and (5) administrative controls. The regulation does not specify the particular requirements to be included in a plant's TSs. In Item 3, 10 CFR 50.36(c)(3) notes that SRs are requirements relating to test, calibration, or inspection to assure that necessary quality of systems and components is maintained.

In general, there are two classes of changes to TS: (1) changes needed to reflect modifications to the design bases (TS are derived from the design basis); and (2) voluntary changes to take advantage of the evolution in policy and guidance as to the required contents and preferred format of TS over time. This amendment deals with the second class of changes.

Requirements for ISi of Class 1, Class 2, Class 3, Class MC, and Class CC components (including supports) are located in 10 CFR 50.55a(g). The regulations in 10 CFR 50.55a(g}(5)(ii) require, in part, that, if a revised ISi program for a facility conflicts with the TS for that facility, the licensee shall apply to the Commission for amendment of the TS to conform the TS to the revised program. The licensee shall submit this application at least 6 months before the start of the period during which the provisions become applicable.

Licensees are required to perform the ISi and testing of snubbers in accordance with Section XI of the ASME Boiler and Pressure Vessel Code (B&PV Code) or the ASME OM Code and the applicable addenda, as required by Section 50.55a(g) of 10 CFR or 10 CFR 50.55a(b)(3}(v},

except where the NRG has granted specific relief, pursuant to 10 CFR 50.55a(g)(6)(i}, or authorized alternatives pursuant to 10 CFR 50.55a(z). (Note: the paragraph headings in 10 CFR 50.55a were changed by Federal Register notice dated November 5, 2014 (79 FR 65776), which became effective December 5, 2014 (e.g., 10 CFR 50.55a(a)(3) is now 10 CFR 50.55a(z). See the cross-reference tables, which are cited in the notice, at ADAMS Accession No. ML14015A191 and ADAMS package Accession No. ML14211A050).

As discussed in NRC Regulatory Issue Summary 2010-06, "lnservice Inspection and Testing Requirements of Dynamic Restraints (Snubbers)," dated June 1, 2010 (ADAMS Accession No. ML101310338), licensees have the option to control the ASME Code-required ISi and testing of snubbers through its TSs or through licensee-controlled documents (e.g., the Technical Requirements Manual).

The regulations in 10 CFR 50.55a(b)(3)(v) allow licensees the option of using the inservice examination and testing provisions for snubbers in ASME B&PV Code Section XI or the ASME OM Code. However, 10 CFR 50.55a(b)(3)(v)(B) states, in part, that licensees shall comply with the provisions for examining and testing snubbers in Subsection ISTD of the ASME OM Code and make appropriate changes to its TS or licensee-controlled documents when using the 2006 Addenda or later editions and addenda of Section XI of the ASME B&PV Code. OCNGS is currently using the 2007 Edition with the 2008 Addenda of the Section XI ASME Code.

The fifth 10-year ISi interval at OCNGS began on January 15, 2013, and is scheduled to end January 14, 2023. Currently, snubber examination and testing are performed in accordance with the specific requirements of TS 4.5.M and the OCNGS plant procedures. For the rest of the fifth 10-year ISi interval at OCNGS, the snubber program will meet the requirements of the ASME OM Code, Subsection ISTD, Edition 2004 with 2005 and 2006 Addenda per 10 CFR 50.55a(b)(3)(v).

3.0 TECHNICAL EVALUATION

3.1 Licensee's Proposed TS Changes and Basis Information The proposed changes to the OCNGS TSs are summarized below:

• TS Specification 4.5.M.1 of TS 4.5.M, "Shock Suppressors (Snubbers)," will be revised to replace specific SRs for demonstrating snubber operability with the newly added Administrative Control Section 6.25, "Snubber Inspection Program, as follows:

TS SR 4.5.M.1 Each snubber shall be demonstrated OPERABLE by performance of the Snubber Inspection Program.

(Note: All other details about snubber visual inspection, functional testing and service life program requirements as described in TS SR 4.5.M a, b, c, d, e, and f, which are proposed to be deleted, are not being repeated here).

• Section 6.25, "Snubber Inspection Program, will be added to the TS "Administrative Controls, Section 6 to provide a description of the snubber testing program as follows:

6.25 Snubber Inspection Program This program conforms to the examination, testing, and service life monitoring for dynamic restraints (snubbers) in accordance with 10 CFR 50.55a inservice inspection (ISi) requirements for supports. The program shall be in accordance with the following:

a. This program shall meet 10 CFR 50.55a(g) ISi requirements for supports.

b. The program shall meet the requirements for ISi of supports set forth in subsequent editions of the Code of Record and addenda of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV)

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(a),

50.55a(a)(1 ), 50.55a(a)(1 )(i), and 50.55a(a)(1 )(iv), subject to its limitations and modifications, and subject to Commission approval.

c. The program shall, as allowed by 10 CFR 50.55a(b)(3)(v)(B), meet Subsection ISTA, "General Requirements," and Subsection ISTD, "Preservice and lnservice Examination and Testing of Dynamic Restraints (Snubbers) in Light-Water Reactor Nuclear Power Plants, in lieu of Section XI of the ASME B&PV Code ISi requirements for snubbers, or meet authorized alternatives pursuant to 10 CFR 50.55a(z).

d. The 120-month program updates shall be made in accordance with 10 CFR 50.55a (including 10 CFR 50.55a(g)(4)(ii)) subject to the conditions listed therein.

e. Records of the service life of all snubbers, including the date which the service life commences, and associated installation and maintenance records shall be maintained for the duration of the Facility Operating License.

For the fifth 10-year ISi interval, as permitted by 10 CFR 50.55a(b)(3)(v), OCNGS intends to adopt Subsection ISTD, of the ASME OM Code, 2004 Edition with 2005 and 2006 addenda.

As such, the proposed changes to TS 4.5.M are required to conform the TSs to this revised snubber program.

3.2 NRC Staff Evaluation of Proposed Changes The licensee has developed a detailed "Snubber lnservice Program," as a licensee-controlled document at OCNGS, which will be implemented in lieu of the deleted TS snubber examination, testing and service life program requirements. This "Snubber Inspection Program," will contain snubber examination, testing and service life monitoring program and will be based on the requirements referenced in the TS Administrative Control Section 6.25.

The NRC staff has reviewed of the submitted LAR related to the snubber examination and testing program described in TS 4.5.M, "Shock Suppressors (Snubbers), and concludes that the proposed amendment to revise the Snubbers TS 4.5.M and to add new "Snubber Inspection Program, in the TS Administrative Control Section 6.25 are acceptable. The NRC staff finds that the program requirements are consistent with the ISi and testing requirements for snubbers as required by 10 CFR 50.55a. The NRC staff also notes that the snubber ISi and testing program at OCNGS will be performed per the requirements of the ASME OM Code 2004 Edition with 2005 and 2006 Addenda), Subsection ISTD, as allowed by 10 CFR 50.55a(b)(3)(v)(B).

Therefore, the NRC staff concludes that the proposed amendment to revise TS 4.5.M and to add new TS 6.25 is acceptable.

Based on the above finding that the "Snubber Inspection Program" is consistent with 10 CFR 50.55a, the NRC staff further finds that the examination, testing and service life monitoring for snubbers in accordance with the Snubber Inspection Program, as required by TS SR 4.5.M, is sufficient to demonstrate that snubbers are OPERABLE in accordance with TS 4.5.M.1. Therefore, the NRC staff concludes that the proposed changes to TS SR 4.5.M are consistent with the requirements in 10 CFR 50.36(c)(3) and, therefore, are acceptable.

Based on the above considerations, the NRC staff concludes that the proposed amendment is acceptable.

3.3 NRC Staff Technical Conclusion As set forth above, the NRC staff concludes that the proposed amendment to revise the Snubber TS 4.5.M is acceptable. Specifically, the change replaces the TS SR 4.5.M.1 requirements for snubber examination, testing and service life monitoring with newly added ISi program requirements for snubbers contained in TS Administrative Control Section 6.25, "Snubber lnservice Program."

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the New Jersey State official was notified of the proposed issuance of the amendment. The State official had no comments.

5.0 ENVIRONMENTAL CONSIDERATION

The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes SRs.

The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding on July 8, 2014 (79 FR 38590). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.

6.0 CONCLUSION

The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) there is reasonable assurance that such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.
