UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 165 TO RENEWED FACILITY OPERATING LICENSE NO. NPF-69 NINE MILE POINT NUCLEAR STATION, LLC LONG ISLAND LIGHTING COMPANY EXELON GENERATION COMPANY, LLC.

NINE MILE POINT NUCLEAR STATION, UNIT 2 DOCKET NO. 50-410

1.0 INTRODUCTION

By letter dated April 5, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML17095A081 ), Exelon Generation Company, LLC (the licensee),

submitted a license amendment request (LAR) for Nine Mile Point Nuclear Station, Unit 2 (Nine Mile Point 2), to adopt Technical Specifications Task Force (TSTF) Traveler 283-A, Revision 3, "Modify Section 3.8 Mode Restriction Notes." TSTF travelers are generic changes to the improved Standard Technical Specifications (STS). This safety evaluation input specifically evaluates the adoption of TSTF Traveler 283-A, Revision 3, for Nine Mile Point 2.

TSTF Traveler 283-A, Revision 3, introduced a modification of the mode restriction note for 14 different surveillance requirements (SRs) in NUREG-1433, Revision 4, "Standard Technical Specifications, General Electric BWR [Boiling Water Reactor]/4 Plants" (ADAMS Accession No. ML12104A192). The revised surveillance notes will allow full or partial performance of surveillance requirements (SRs) for the purposes of reestablishing operability provided an assessment determines that the safety of the plant is maintained or enhanced. The licensee has chosen to adopt twelve of the modifications. Specifically, SRs 3.8.1. 7 through 3.8.12, 3.8.1.14 through 3.8.1.17, 3.8.4.7, and 3.8.4.8, in the Nine Mile Point 2 Technical Specifications (TSs) are modified by changing the mode restriction note to allow the SR, or parts of it, to be performed to reestablish operability. The proposed changes do not involve any physical alterations to the installation.

2.0 REGULATORY EVALUATION

2.1 Background Certain SRs related to TS 3.8 currently limit performance of the SR to plant operating modes other than Modes 1 or 2 or, in some cases, Modes 1, 2, or 3, by a note placed atop each SR.

Enclosure 2

TSTF Traveler 283-A, Revision 3, revised SR notes in STS 3.8.1, "AC [Alternating Current]

Sources - Operating," and 3.8.4, "DC [Direct Current] Sources - Operating," to allow full or partial performance of the SRs in the prohibited modes to reestablish operability, provided an assessment determines the safety of the plant is maintained or enhanced. The existing notes are modified to state that while the SRs are normally prohibited in, for example, "Modes 1 or 2,"

they may be performed to reestablish operability, provided an assessment determines the safety of the plant is maintained or enhanced.

2.2 Proposed TS Changes 2.2.1 Current Nine Mile Point 2 TSs SR 3.8.1.7 note 1 states:

This Surveillance shall not normally be performed in MODE 1, 2, or 3 (not applicable to Division 3). However, portions of the Surveillance may be performed to reestablish OPERABILITY provided an assessment determines the safety of the plant is maintained or enhanced. Credit may be taken for unplanned events that satisfy this SR.

The SR 3.8.4.8 note is revised to:

This Surveillance shall not normally be performed in MODE 1, 2, or 3 (not applicable to Division 3). However, portions of the Surveillance may be performed to reestablish OPERABILITY provided an assessment determines the safety of the plant is maintained or enhanced. Credit may be taken for unplanned events that satisfy this SR.

2.3 Regulatory Requirements and Guidance 2.3.1 Regulatory Requirements In Title 10 of the Code of Federal Regulations (10 CFR) Section 50.36, "Technical specifications," the U.S. Nuclear Regulatory Commission (NRC or the Commission) established its regulatory requirements related to the content of TSs. Pursuant to 10 CFR 50.36, TSs are required to include items in the following five specific categories: (1) safety limits, limiting safety system settings, and limiting control settings; (2) limiting conditions for operation (LCOs);

(3) SRs; (4) design features; and (5) administrative controls. This regulation does not specify the particular requirements to be included in a plant's TSs.

As discussed in 10 CFR 50.36(c)(3), SRs are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the LCOs will be met.

The regulation at 10 CFR 50.65(a)(4) states that before performing maintenance activities (including, but not limited to surveillance, post-maintenance testing, and corrective and preventive maintenance), the licensee shall assess and manage the increase in risk that may result from the proposed maintenance activities. The scope of the assessment may be limited

to structures, systems, and components that a risk-informed evaluation process has shown to be significant to public health and safety.

2.3.2 Guidance The NRC staff used the following guidance documents in its review:

  • TSTF Traveler 283, Revision 3, "Modify Section 3.8 Mode Restriction Notes," dated April 13, 2000.

3.0 TECHNICAL EVALUATION

TSTF Traveler 283-A, Revision 3, "Modify Section 3.8 Mode Restriction Notes," revised SR notes in Standard Technical Specifications TS 3.8.1, "AC Sources - Operating," and 3.8.4, "DC Sources - Operating," to allow full or partial performance of the SRs in the prohibited modes to reestablish operability, provided an assessment determines the safety of the plant is maintained or enhanced and was approved by the NRC. As stated on page 4 of 8 of Attachment 1 of the LAR the licensee determined that the justification for the change presented in the approved traveler is applicable to Nine Mile Point 2.

The licensee proposed revisions to the following Nine Mile Point 2 SRs: 3.8.1.7 through 3.8.12, 3.8.1.14 through 3.8.1.17, 3.8.4.7, and 3.8.4.8. These SRs currently have notes prohibiting their performance in Modes 1 or 2 or Modes 1, 2, or 3. The notes are modified to state that while normally prohibited "in Modes 1 or 2," or "in Modes 1, 2, or 3," the SR, or portions of it, may be performed to reestablish operability, provided an assessment determines the safety of the plant is maintained or enhanced.

Justification As stated on page 4 of 8 of Attachment 1 of the LAR, the licensee uses a summary of the approved traveler justification as its justification for the changes as follows:

The proposed changes will reduce the potential for a plant shutdown should corrective maintenance (planned or unplanned) performed during power operation result in the need to perform any of the revised SRs to demonstrate operability.

The allowance to perform the SRs in currently prohibited Modes is restricted to only allow the SRs to be performed for the purpose of reestablishing operability (e.g. post-work testing following corrective maintenance, corrective modification, deficient or incomplete surveillance testing, and other unanticipated operability concerns) provided an assessment determines plant safety is maintained or enhanced. This assessment shall, as a minimum, consider the potential outcomes and transients associated with a failed SR, a successful SR, and a perturbation of the offsite or onsite system when they are tied together or operated independently for the SR; as well as the operator procedures available to cope with these outcomes. These shall be measured against the avoided risk of a plant shutdown and startup to determine that plant safety is maintained or

enhanced when the SR is performed. Risk insights or deterministic methods may be used for this assessment.

Note that the Maintenance Rule provision contained in 10 CFR 50.65(a)(4) states that before performing maintenance activities, the licensee shall assess and manage the increase in risk that may result from the proposed maintenance activities. This includes the performance of SRs to reestablish operability.

Therefore, in addition to the assessment required by the SR Notes, an assessment of plant risk will also be performed.

TS Variation 3 The Nine Mile Point 2 TSs contain a Surveillance Frequency Control Program for use by the licensee in determining the appropriate surveillance frequency. This is satisfactory since the change to the Nine Mile Point 2 TSs was approved by the NRC in Amendment No. 152 to Nine Mile Point 2 Renewed Facility Operating License No. NPF-69 on November 30, 2015 (ADAMS Accession No. ML15317A307).

The licensee explained three variations from TSTF-283-A in tabular format with justifications on page 3 of 8 of Attachment 1 of the LAR. A modified reproduction is as follows:

Variation Justification TSTF-283-A for BWR/4 contained a Nine Mile Point 2 TSs do not have this SR, as SR 3.8.1.8 to verify transfer between offsite it is not part of the Nine Mile Point 2 design.

TSTF-283-A for BWR/4 contained a The Nine Mile Point 2 equivalent SR is SR 3.8.1.19 to verify response to a loss of SR 3.8.1.17. The Nine Mile Point 2 SR offsite power signal and ECCS [emergency includes three additional requirements under core cooling system] actuation signal. sub-criteria c. These additional requirements already in the Nine Mile Point 2 SR are not being changed and are being retained.

TSTF-283-A for BWR/4 contained a Nine Mile Point 2 TS SR 3.8.4.6 does not SR 3.8.4.6 to verify battery charger have the note prohibiting performance in performance. Modes 1, 2, or 3. Therefore, it is not being included in the submittal.

Bases Variation Additionally, the licensee presented a minor change from the approved traveler bases changes.

Eight of the twelve SRs presented for change at Nine Mile Point 2 currently restrict their activity in Modes 1, 2, and 3, while the STS bases inserts provided in the approved traveler identify only Modes 1 and 2. Therefore, the TS bases markups for these SRs were modified so that the current Nine Mile Point 2 TS mode restrictions are followed for these SRs. The applicable SRs are as follows:

3.8.1.9 3.8.1.14 3.8.1.16 3.8.4.7 3.8.1.11 3.8.1.15 3.8.1.17 3.8.4.8

Assessment:

The NRC staff reviewed the proposed revisions to the following Nine Mile Point 2 SRs: 3.8.1.7 through 3.8.12, 3.8.1.14 through 3.8.1.17, 3.8.4.7, and 3.8.4.8. The staff determined that the changes are identical to those made to the corresponding SRs for BWR/4 plants contained in the approved traveler. Some of the Nine Mile Point 2 SR notes contain additional amplifying wording (e.g., not applicable to the Division 3 DG). The NRC staff reviewed the additional wording and determined that it is being retained as is and does not interfere with or modify the overall objective of the change.

The NRC staff agrees with the licensee's justification for the changes contained in the LAR and has determined that the justification is acceptable. Based on the evaluation above, the staff has determined that the proposed changes to the Nine Mile Point 2 TSs are acceptable and consistent with TSTF-283-A, Revision 3. The NRC staff concludes that the requirements of 10 CFR 50.36(c)(3) will continue to be met because the revised SRs provide the appropriate surveillances to ensure the necessary quality of components is maintained and the associated LCOs will be met.

The NRC staff also reviewed the associated proposed bases changes and the stated variation.

The variation simply allows the current TS SR mode restrictions to be carried forward into the bases explanation as applicable. This allows the Nine Mile Point 2 bases to remain consistent with the Nine Mile Point 2 TSs. The NRC staff has no objections to the proposed bases changes because it determined they are consistent with the bases changes included in the approved traveler and the Nine Mile Point 2 TSs. Nine Mile Point 2 makes TS bases changes in accordance with TS 5.5.10, "Technical Specifications (TS) Bases Control Program."

4.0 STATE CONSULTATION

In accordance with the Commission's regulations, the New York State official was notified of the proposed issuance of the amendment on November 9, 2017. 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 surveillance requirements. 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 (June 19, 2017; 82 FR 27887). 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 staff 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.
