LR-N17-0140 Request for Additional Information (RAI)

Regarding Proposed License Amendment Accident Monitoring Instrumentation Technical Specifications Salem Nuclear Generating Station, Unit Nos. 1 and 2 Docket Nos. 50-272 and 50-311 By letter dated November 17, 2016, as supplemented by letter dated August 7, 2017 (Agencywide Documents Access and Management System (ADAMS) Accession Nos.

ML16323A279 and ML17219A160, respectively), PSEG Nuclear LLC (PSEG, the licensee) submitted a license amendment request (LAR) for Salem Nuclear Generating Station (Salem),

Unit Nos. 1 and 2. The amendments would revise Technical Specification (TS) requirements regarding accident monitoring instrumentation. Specifically, the amendments would modify the list of instruments required to be operable based on implementation of Regulatory Guide 1.97, Revision 2, dated December 1980, "Instrumentation for Light-Water-Cooled Nuclear Power Plants to Assess Plant and Environs Conditions During and Following an Accident" (ADAMS Accession No. ML06075052). In addition, allowed outage times (AOTs) and required actions for inoperable accident monitoring instrumentation channels would be revised to be consistent with NUREG-1431, Revision 4, "Standard Technical Specifications- Westinghouse Plants" (ADAMS Accession Nos. ML12100A222 and ML12100A228).

The NRC staff is reviewing your submittal and has determined that additional information is needed to complete its review. The specific information requested is addressed below.

Technical Specifications Branch (STSB}

Reviewer: Margaret Chernoff RAI*STSB-1 On July 22, 1993 (58 FR 39132), the Commission published a "Final Policy Statement on Technical Specifications Improvements for Nuclear Power Reactors" (Final Policy Statement) which discussed the criteria to determine which items are required to be included in the TSs as Limiting Conditions for Operation (LCOs). The criteria were subsequently incorporated into the regulations by an amendment to 10 CFR 50. 36 (60 FR 36953, July 19, 1995). Specifically, 10 CFR 50. 36(c)(2)(ii) requires that a TS LCO be established for each item meeting one or more of the following criteria:

Criterion 1: Installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary.

Criterion 2: A process variable, design feature, or operating restriction that is an initial condition of a design basis accident or transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier.

1

LR-N17-0140 Criterion 3: A structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a design basis accident or transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier.

Criterion 4: A structure, system, or component which operating experience or probabilistic risk assessment has shown to be significant to public health and safety.

The Bases for the Standard Technical Specifications (STS)- Westinghouse Plants (NUREG 1431, Volume 2, Revision 4; ADAMS Accession No. ML121 OOA228) provides an explanation of why the instrumentation listed in LCO 3.3.3, Accident Monitoring Instrumentation, satisfies the criteria of 10 CFR 50.36 as follows:

PAM [Post Accident Monitoring] instrumentation that meets the definition of Type A in Regulatory Guide 1.97 satisfies Criterion 3 of 10 CFR 50. 36(c)(2)(ii).

Category I, non-Type A, instrumentation must be retained in TS because it is intended to assist operators in minimizing the consequences of accidents.

Therefore, Category I, non-Type A, variables are important for reducing public risk.

The PAM instrumentation is listed in Table 3.3. 3-1 of the STS. The function of Penetration Flow Path Containment Isolation Valve Position is included in this Table. However, because the specific instruments may vary from plant to plant, the STS contains a note stating that Table 3.3. 3-1 shall be amended for each unit as necessary to list:

1. All Regulatory Guide 1.97, Type A instruments and
2. All Regulatory Guide 1.97, Category I, non-Type A instruments in accordance with the unit's Regulatory Guide 1.97, Safety Evaluation Report.

As discussed in the LAR, all instruments identified as Type A variables, or non-Type A but Category 1, were evaluated by the licensee and are proposed to be added into the Salem, Unit Nos. 1 and 2, TS Tables 3.3-11 and 4.3-11, with the following two exceptions: (1) containment isolation valve position; and (2) containment hydrogen concentration. The LAR indicates that the containment isolation valve position function is a Type B, Category 1 variable. The LAR states that this is not required to ensure adequate information is available to operators to verify containment operability and the accomplishment of containment isolation when required.

NRC approved Topical Report (TR) WCAP-15981-NP-A (ADAMS Accession No. ML103560687) provides technical justification for identifying PAM instrumentation that should be included in the TSs for Westinghouse plants. The TR also provides a methodology that could be used by licensees to reassess the PAM instrumentation that should be included in plant-specific TSs. The TR states that the containment isolation valve position indication function satisfies Criterion 4 of 10 CFR 50. 36(c)(2)(ii) and, accordingly, should be included in TS

3. 3. 3 in NUREG-1431. Section 3.2.12 of the NRC staff's safety evaluation for the TR agrees with the TR report conclusion that this function should be included in the PAM TSs.

LR*N17*0140 The STS are a generic set of TSs that satisfy the regulations in 10 CFR 50.36. However, the provisions of the STS may not be applicable to any given facility because of that facility's unique design or licensing basis. Please describe the unique characteristics of Salem that were used to conclude that an exception to the STS are appropriate for the containment isolation valve position indication function. Please also address:

1) How the existing Salem TSs provide assurance that the operators can confirm containment isolation during an accident and during the post-accident monitoring phase?
2) Why the containment isolation valve position indication function is listed as a Type B, Category 1 variable if it is not necessary to ensure adequate information is available to operators to verify containment isolation has occurred?
3) Why the containment isolation valve position indication function doesn't satisfy Criterion 4 of 10 CFR 50.36(c)(2)(ii) with respect to the Salem licensing and design basis.

PSEG Response to RAI*STSB-1 PSEG is responding to this RAI by adding the containment isolation valve position indication function to the Salem Unit 1 and Unit 2 TS Tables 3. 3-11 and 4.3-11. PSEG is adopting the STS actions and the associated notes. An additional note (c) is added to Table 3. 3-11 to modify the Action for having the number of OPERABLE accident monitoring channels less than the minimum number of channels shown in Table 3. 3-11 for penetration flow paths with only one installed control room indication channel consistent with NUREG-1431.
