L-MT-15-030 NRC Question 2 The ESEP submittal identifies the Residual Heat Removal Service Water System as a flow-path for Phase 2 Core Cooling; however, it appears that the ESEL does not contain components within this flow-path, except for the passive RHR system heat exchangers.

Confirm that no additional components within this flow-path are required to be evaluated per the ESEP guidance. For example, confirm if any motor-operated valves in the identified flow-path are required to change position and whether they are feasible to be operated manually and locally. In addition, if these motor operated valves can be operated manually, confirm that this operator manual action is the credited action as a part of the FLEX strategies and the Sequence of Events.

NRC Question 4 8 relays in the ESEL are identified as bad actors, and are assigned a functional HCLPF capacity = 0.0. Of the 18 remaining relays, 17 relays are designated with a HCLPF capacity = 0.21g, based on the anchorage capacity of the parent (i.e., rule of the box). For these 17 relays, identify the functional HCLPF capacities, and also discuss how in-cabinet amplification was considered in determining the functional capacity for each relay.

L-MT-15-030 NRC Question 6 There are approximately 50 ESEL items identified as inaccessible because they are inside the drywell. The licensee does NOT intend to complete a walk-by or remote visual of the inaccessible ESEL items at a later date. It is relying on A-46 walkdown results, which are around 20 years old. This appears to be inconsistent with the augmented approach proposed by EPRI and accepted by NRC. Discuss the technical basis why these approximately 50 items do not need to be looked at, in order to verify condition and re-affirm the A-46 walkdown results.

NSPM Response For inaccessible components, NSPM relied on walk downs performed to meet the A-46 issue, the Recommendation 2.3 seismic walk downs performed in 2013 and in specific cases, other information as described below. The 2013 walkdowns observed the following components and areas in the drywell: (1) inboard Main Steam Isolation Valve (MSIV) - AO-2-80A, (2) SRV - RV-2-71A, (3) area walk-bys on the 933 and 951 elevations of the drywell. There was nothing noteworthy found during these walk downs.

There are no regulatory commitments made in the ESEP submittal. Discuss the status of the resolution for each of the 24 components, including the method being employed, the schedule for completing the resolution activities, and the schedule for implementing any required hardware modifications. Also discuss the technical basis for relying on the plant CAP for resolution, in lieu of including regulatory commitments in the ESEP submittal, consistent with the EPRI Augmented Approach guidance.

HPCI valves MO2035, MO2071 and CV3503 are included as part of the ESEL, because although not credited in any FLEX strategy, HPCI is safetyrelated and would automatically initiate in the event of an SBO, and would be secured as part of the ELAP procedures. The test line return path to the CST represents a potential problem for implementation of FLEX strategies because any water that is directed from the Torus to the CST would be lost should either valve fail to close. Therefore, the HPCI test line valves were included in the ESEL to ensure that if HPCI runs prior to being secured; the flow is only directed to the reactor or Torus. MO2035 is closed as part of SBO procedures.

L-MT-15-030 Page 1 of 7 ENCLOSURE 1 MONTICELLO NUCLEAR GENERATING PLANT RESPONSE TO REQUESTS FOR ADDITIONAL INFORMATION (RAIs)

FOR THE EXPEDITED SEISMIC EVALUATION PROCESS REPORT This enclosure provides responses from Northern States Power Company, a Minnesota corporation (NSPM), doing business as Xcel Energy, to requests for additional information (RAls) provided by the Nuclear Regulatory Commission (NRC) in an email dated April 8, 2015 (Reference 1).

The NRC question is provided below in italics font and the NSPM response is provided in normal font.

NRC Question 1 Please clarify if the RCIC CST suction valve should be included in the ESEP scope or discuss why it is not necessary.

NSPM Response The Reactor Core Isolation Cooling (RCIC) to Condensate Storage Tank (CST) suction path is not included in the ESEP scope as it is a secondary path in a seismic event because the CST is not seismically designed.

Following a seismic event that damages the CSTs, the torus RCIC suction valves (MO-2100 and MO-2101) open on low CST level. When these valves are fully open, CST to RCIC suction valve (MO-2102) will close via the relay interlocks described below.

Should MO-2102 fail to close, a check valve in the CST suction line will prevent flow of torus water to the CSTs. Therefore, MO-2102 is not required to close following a seismic event.

Interlocks exist between valve MO-2102 and valves MO-2100 and MO-2101, that are included in the ESEP Scope. For valve MO-2100 this interlock is by relay 13A-K18.

For valve MO-2101 the interlock is by relay 13A-K19. Both of these relays, 13A-K18 and 13A-K19, are included in the Expedited Seismic Equipment List (ESEL) (Table A-1 in the ESEP Report and also in the revised ESEL provided in Enclosure 2 to this letter).

Specifically, these relays are identified as items 285 and 286.

L-MT-15-030 Page 2 of 7 NRC Question 2 The ESEP submittal identifies the Residual Heat Removal Service Water System as a flow-path for Phase 2 Core Cooling; however, it appears that the ESEL does not contain components within this flow-path, except for the passive RHR system heat exchangers.

Confirm that no additional components within this flow-path are required to be evaluated per the ESEP guidance. For example, confirm if any motor-operated valves in the identified flow-path are required to change position and whether they are feasible to be operated manually and locally. In addition, if these motor operated valves can be operated manually, confirm that this operator manual action is the credited action as a part of the FLEX strategies and the Sequence of Events.

NSPM Response The Residual Heat Removal Service Water (RHRSW) flow path for Phase 2 includes piping and manual valves. The RHRSW valves in this flow path were included in the initial ESEL screening and were screened out based on their passive function.

Components in the same flow path which are part of other systems, including Residual Heat Removal (RHR) and Fuel Pool Cooling (FPC), are included in the initial screening and, where appropriate, in the ESEL.

NRC Question 3 In attachment A, the ESEL, there are a large number of items that have blank operating states and note/comment. Please update the table with the appropriate information.

NSPM Response NSPM provides the table in Enclosure 2 with the information requested, including:

Solenoid Valves (SV) normal and desired states, Hard Pipe Vent (HPV) Air Operated (AO) Valves normal and desired states, Safety Relief Valves (SRV) normal and desired states, Updated notes to identify components included only for pressure boundary considerations.

NRC Question 4 8 relays in the ESEL are identified as bad actors, and are assigned a functional HCLPF capacity = 0.0. Of the 18 remaining relays, 17 relays are designated with a HCLPF capacity = 0.21g, based on the anchorage capacity of the parent (i.e., rule of the box). For these 17 relays, identify the functional HCLPF capacities, and also discuss how in-cabinet amplification was considered in determining the functional capacity for each relay.

L-MT-15-030 Page 3 of 7 NSPM Response The functional capacities (High Confidence of a Low Probability of Failure (HCLPF)) of the subject 17 relays are shown in Table 4-1 below. Base capacities were drawn from EPRI NP-7147-SL, Seismic Ruggedness of Relays (Reference 2), manufacturer test data, and Seismic Qualification Utility Reports and Testing Standardization (SQURTS) reports, as appropriate.

Table 4-1 HCLPF for Relays Component ID Functional Capacity (g)

Component ID Functional Capacity (g) 13A-K1 2.40 13A-K22 2.40 13A-K2 2.40 13A-K27 2.40 13A-K6 2.40 13A-K31 3.20 13A-K7 3.20 13A-K32 2.40 13A-K10 2.40 13A-K33 4.00 13A-K12 2.40 13A-K34 2.40 13A-K16 2.40 13A-K37 4.80 13A-K18 2.40 K102A 1.06 13A-K19 2.40 In lieu of cabinet amplification factors, the in-cabinet response spectra were calculated for these relays using the procedure from EPRI NP-7148-SL, Procedure for Evaluating Nuclear Power Plant Relay Seismic Functionality (Reference 3), and the GenRS software. Thus, cabinet amplification factors were not required to be determined.

NRC Question 5 12 switches in the ESEL are identified as No public capacity data available for this item. and are assigned a HCLPF capacity = 0.0. Of the remaining 37 switches, 35 switches apparently have a HCLPF capacity controlled by something other than function. For these 35 switches, identify the functional HCLPF capacities, and also discuss how in-cabinet amplification was considered in determining the functional capacity for each switch.

NSPM Response The functional capacities (HCLPF) of the 35 subject switches are listed in Table 5-1 below. Base capacities were drawn from EPRI NP-7147-SL (Reference 2),

manufacturer test data, and SQURTS testing, as appropriate. In-cabinet amplification factors were conservatively taken uniformly as 4.5 from EPRI NP-6041-SL, A Methodology for Assessment of Nuclear Power Plant Seismic Margin, Revision 1 (Reference 4), calculated using the procedure from EPRI NP-7148-SL using GenRS, or

4.5 Notes

1. GenRS used to calculate the In-cabinet response spectra.
2. Item does not belong within a host; thus no in-cabinet amplification occurs.

L-MT-15-030 Page 5 of 7 NRC Question 6 There are approximately 50 ESEL items identified as inaccessible because they are inside the drywell. The licensee does NOT intend to complete a walk-by or remote visual of the inaccessible ESEL items at a later date. It is relying on A-46 walkdown results, which are around 20 years old. This appears to be inconsistent with the augmented approach proposed by EPRI and accepted by NRC. Discuss the technical basis why these approximately 50 items do not need to be looked at, in order to verify condition and re-affirm the A-46 walkdown results.

NSPM Response For inaccessible components, NSPM relied on walk downs performed to meet the A-46 issue, the Recommendation 2.3 seismic walk downs performed in 2013 and in specific cases, other information as described below. The 2013 walkdowns observed the following components and areas in the drywell: (1) inboard Main Steam Isolation Valve (MSIV) - AO-2-80A, (2) SRV - RV-2-71A, (3) area walk-bys on the 933 and 951 elevations of the drywell. There was nothing noteworthy found during these walk downs.

The ESEL equipment that was determined to be inaccessible (due to location in the drywell) included valves, accumulators and temperature elements. Each component type was assessed as follows:

For valves, the Seismic Review Team (SRT) gathered valve drawings in addition to the A-46 Screening Evaluation Work Sheets (SEWS) and pictures, and performed the valve evaluation based on the methodology presented in EPRI NP 6041-SL (Reference 4).

Temperature elements were evaluated based on A-46 walk down notes and pictures.

These components are directly attached/secured to structural components. Therefore, the SRT determined that the information was adequate for the ESEP purpose.

Accumulators were evaluated based on the A-46 notes and pictures. Typically two large U bolt connections were utilized to secure the accumulator. With the large margin of these items, the SRT determined that the information was adequate for the ESEP purpose.

NRC Question 7 Section 8.2 identifies 24 ESEL components that have a HCLPF capacity less than the RLGM; 23 are relays and switches. A more detailed analysis of capacity for the RHR Heat Exchanger E-200B anchorage, and changing the bolting material are discussed as options, but have not been implemented. 20 of the 23 relays and switches lack adequate qualification test data. Several avenues for resolution are discussed, but none have been implemented. In Section 8.4, the Licensee indicates that the 24 components

L-MT-15-030 Page 6 of 7 are entered into the plant Corrective Actions Program (CAP) for resolution. The analysis and completion of the 24 components should have been part of the submittal.

There are no regulatory commitments made in the ESEP submittal. Discuss the status of the resolution for each of the 24 components, including the method being employed, the schedule for completing the resolution activities, and the schedule for implementing any required hardware modifications. Also discuss the technical basis for relying on the plant CAP for resolution, in lieu of including regulatory commitments in the ESEP submittal, consistent with the EPRI Augmented Approach guidance.

NSPM Response Below, in Table 7-1 is a summary of the 24 components identified in the ESEP report that do not have sufficient seismic capacity to withstand the Review Level Ground Motion (RLGM) and the plan and schedule for resolving each item. Each components HCLPF will exceed RLGM when the resolution activities are completed.

NRC Commitments 1 - A letter will be provided to the NRC indicating the proposed resolution applicable to each component and the expected timeframe for completion of the resolution when this information has been developed.

2 - A letter will be provided to the NRC summarizing the HCLPF results of each component and confirming the resolution of each component. This letter will be sent within 60 days of completion of the resolution activity(ies) for the final completed component from Table 7-1.

Table 7 Components Requiring Action to Verify HCLPF Capacity Values are Met Components Proposed Resolution Schedule E-200B - bolts on heat exchanger supports Complete further evaluation and implement modifications, if required, to increase seismic margin so that HCLPF will exceed RLGM for the components identified in this table.

Resolutions will be completed by 12/31/2016 unless a plant outage is needed to implement a modification. In that case, the outage modification will be completed prior to the end of the 2017 refueling outage.
