Browns Ferry ESEP Clarifying Questions
- 1) Section 3.2 of EPRI 3002000704 stated that The selection process for the ESEL should assume the FLEX strategies (modifications, equipment, procedures, etc.) have been implemented. The staff noted that not all non-portable FLEX components have been installed during the development of the licensees ESEP. Clarify whether HCLFP evaluations will be performed to ensure they achieve the RLGM capacity when those non-portable FLEX components are installed in the future and propose any following actions Response: In accordance with ESEP requirements, pre-staged FLEX equipment that is not anchored or connected to electrical or fluid systems is treated as non-installed equipment and evaluated primarily as an interaction concern for the plant. Pre-staged FLEX equipment that is anchored in the plant is treated as installed equipment and if required for the success of the FLEX strategy is evaluated using the ESEP criteria. This is true for FLEX equipment that was installed prior to ESEP submittal and is true for FLEX equipment installed after ESEP submittal.
- 2) Provide the justification why the following components are not included in the ESEL for Units 1,2 & 3:
- FCV-64-18, 19, 20, 21, FSV 84-8B & 8C, and FCV 76-19 & 24 for each unit (These valves may need to be closed for the Hardened Containment Venting Systems (HCVS) to work)
- HCVS Instrumentation such as those for process temperature
- Breaker, such as 1-BKR-071-0019, for MOVs
Response
Component Resolution Valve FCV-64-18 is an eighteen-inch diameter, air-operated, butterfly valve used for primary containment isolation (FSAR Table 5.2-2). This valve is normally closed and the desired FLEX state is for the valve to stay closed. The valve requires air to open and will spring closed,therefore a spurious opening of the valve will not occur. This approach is supported by the EPRI 3002000704 NTTF 2.1 Seismic Augmented FCV-64-18 Approach Guideline Questions & Answers, which states The only Containment Isolation Valves (CIVs) which would be included in the ESEL are those which need to be manipulated as part of implementing a Phase 1 or 2 FLEX strategy.In summary, this item was not included on the ESEL because the valve is normally closed and does not need to change state or be manipulated for Phase 1 or Phase 2 FLEX strategy.
Valve FCV-64-19 is a twenty-inch diameter, air-operated, butterfly valve used for primary containment isolation (FSAR Table 5.2-2). This valve is normally closed and the desired FLEX state is for the valve to stay closed. The valve requires air to open FCV-64-19 and will spring closed, therefore a spurious opening of the valve will not occur. This approach is supported by the EPRI 3002000704 NTTF 2.1 Seismic Augmented Approach Guideline Questions & Answers, which states The only Containment
Component Resolution Isolation Valves (CIVs) which would be included in the ESEL are those which need to be manipulated as part of implementing a Phase 1 or 2 FLEX strategy.In summary, this item was not included on the ESEL because the valve is normally closed and does not need to change state orbe manipulated for Phase 1 or Phase 2FLEX strategy.
Valve FCV-64-20 is a twenty-inch diameter, air-operated butterfly valve used for primary containment isolation (FSAR Table 5.2-2). This valve is normally closed and the desired FLEX state is for the valve to stay closed. The valve will spring open and requires air to close; therefore, a spurious opening of the valve could possibly occur with loss of service air. Manual action can be used to keep the valve closed. However, containment isolation would still be accomplished by the check valve that is located FCV-64-20 within the flow path, (DWG 47E610-64-1), regardless of the state of FCV-64-20.
Rather than credit valve FCV-64-20 and the air accumulator needed to keep the valve closed, the associated check valve CKV-064-0800 was selected as the success path for this containment isolation function.
In accordance with the Seismic Evaluation Guidance - Augmented Approach for the Resolution of the Fukushima Near-Term Task Force Recommendation 2.1 - Seismic, Section 3.2, the check valve was excluded from the ESEL.
Valve FCV-64-21 is a twenty-inch diameter, air-operated butterfly valve used for primary containment isolation. (FSAR Table 5.2-2). This valve is normally closed and the desired FLEX state is for the valve to stay closed. The valve will spring open and requires air to close; therefore, a spurious opening of the valve could possibly occur with loss of service air. Manual action can be used to keep the valve closed. However, containment isolation would still be accomplished by the check valve that is located FCV-64-21 within the flow path, (DWG 47E610-64-1), regardless of the state of FCV-64-21.
Rather than credit valve FCV-64-21 and the air accumulator needed to keep the valve closed, the associated check valve CKV-064-0801 was selected as the success path for this containment isolation function.
In accordance with the Seismic Evaluation Guidance - Augmented Approach for the Resolution of the Fukushima Near-Term Task Force Recommendation 2.1 - Seismic, Section 3.2, the check valve was excluded from the ESEL.
Valve FSV-84-8B is atwo-inch diameter, solenoid-operated, globe valve used for primary containment isolation (FSAR Table 5.2-2). This valve is normally closed and the desired FLEX state is for the valve to stay closed. The valve requires AC power to open and will spring closed, therefore a spurious opening of the valve will not occur.
This approach is supported by the EPRI 3002000704 NTTF 2.1 Seismic Augmented FSV-84-8B Approach Guideline Questions & Answers, which states The only Containment Isolation Valves (CIVs) which would be included in the ESEL are those which need to be manipulated as part of implementing a Phase 1 or 2 FLEX strategy.In summary, this item was not included on the ESEL because the valve is normally closed and does not need to change stateor be manipulated for Phase 1 or Phase 2FLEX strategy.
Valve FSV-84-8C is atwo-inch diameter, solenoid-operated, globe valve used for primary containment isolation (FSAR Table 5.2-2). This valve is normally closed and the desired FLEX state is for the valve to stay closed. The valve requires AC power to open and will spring closed therefore a spurious opening of the valve will not occur.

Valve FCV-76-24 is a ten-inch diameter, air-operated, butterfly valve used for primary containment isolation (FSAR Table 5.2-2). This valve is normally closed and the desired FLEX state is for the valve to stay closed. The valve requires air to open and will spring closed, therefore a spurious opening of the valve will not occur.

ESEL instrumentation currently includes drywell pressure, drywell temperature, torus temperature and torus level. The components included are those presented in the BFN Overall Integrated Plan (OIP) for containment HCVS Instrumentation control. Seismic Evaluation Guidance - Augmented Approach for the Resolution of the Fukushima Near-Term Task Force Recommendation 2.1, Table 3-1 provides containment pressure, suppression pool temperature,and suppression pool level as parameters required for containment control.
Breakers in MCCs or busses are treated as rule of the box. This is consistent with the MOV Breakers EPRI 3002000704 NTTF 2.1 Seismic Augmented Approach Guideline Questions &
Answers,
However, the control point for the IPEEE RLE is not discussed. In order to confirm that the control point of the IPEEE RLE is at the same location as the GMRS, provide the IPEEE RLE control point.
Response: The IPEEE RLE control point is the same as the SSE control point and GMRS control point.
- 4) Section 6.2 of the ESEP Report describes ESEL component screening using Table 2-4 of EPRI NP-6041-SL. This table is applicable to components located up to 40 ft above grade. The ESEP report is silent concerning screening or HCLPF calculations at
elevations beyond 40 ft above grade. Therefore, describe how ESEL components located at elevations beyond 40 ft above grade either were screened or had their HCLPF capacities calculated, including specific references for the applicable guidance utilized.
Response: Effective Grade at BFN is at approximately 550 ft. as shown in TVA Calculation CDQ0000940339. Components located above elevation 590 ft. are included in the attached table. Most components were evaluated in the earlier A-46 or seismic IPEEE program and are indicated as such. For components above base elevation, the Table 2-4 of EPRI NP-6041-SL screening capacities were conservatively interpreted as applicable for comparison with in-structure response spectra (ISRS). That is, the 5% damped spectral acceleration capacity was taken as 1.2g for the center capacity column of Table 2-4 of EPRI NP-6041 SL, and used for comparison to ISRS. Note that according to Section B.2 of EPRI 1019200 (Seismic Fragility Applications Guide Update), the appropriate capacity for the center capacity column of Table 2-4 of EPRI NP-6041 SL should be increased to 1.8g for comparison with clipped ISRS. This was done for ESEP.The additional HCLPF evaluations are performed in TVA Calculation CDQ0009992014000268.
- 5) Section 6.3.3 of the ESEP report indicates that HCLPF capacity evaluations were recommended for 12 components; however, the results for a number of these components could not be identified in the text portion of the report or the HCLPF table, e.g., main control room benchboard, blocks walls, Terry turbine control box, RCIC Back-Up Control Panel, and LPNL Instrument Rack. Please provide the HCLPF values and failure modes for those items.
Response: The requested information is documented in TVA Calculation CDQ0009992014000268, Rev. 02. Results are as follows:
HCLPF Capacity Failure Description for RLE at Mode Rock Outcrop Main Control Room Benchboard 0.62g Functional Block Walls >0.30g Structural Integrity and Anchorage (per 80-11 program)
Terry Turbine Control Box (controls) 0.85g Functional RCIC Back-up Control Panel 0.62g Functional LPNL Instrument Rack 0.74g Anchorage
- 6) The licensee reported that the ESEL items included in the IPEEE program are screened out based on previous evaluations against the IPEEE RLE which envelops the ESEP
RLGM for frequencies between 1 and 10 Hz and on recent walk-by verifications.
Section 6.4 of the ESEP report states that the ESEL items not included in the IPEEE program are evaluated using the criteria in EPRI NP6041SL. Section 5.2 of the ESEP report states that The RLGM ISRS for the Browns Ferry Nuclear Plant are generated by scaling the design basis SSE up to 0.3 g RLE as determined in the Seismic IPEEE.
Please clarify if the licensee evaluated ESEL items not included in the IPEEE program using the ISRS developed by scaling the SSE up to the IPEEE RLE with a PGA of 0.3 g, instead of the ESEP RLGM with a PGA of 0.4 g, and, if so, provide the justification.
Response: ESEL items not included in the IPEEE program were evaluated using the ISRS developed by scaling the SSE up to the IPEEE RLE with a PGA of 0.3g. It is appropriate to use the IPEEE RLE with a PGA of 0.3g because that spectra envelops the ESEP RLGM with a PGA of 0.4g in the 1-10 Hz range, which is the frequency range of interest. This is shown graphically in Figure 6-1 of the Browns Ferry Nuclear Plant ESEP Report.
- 7) Section 7.0 states that some components inside drywell were not accessible during the walk by verifications. Those components were later assessed by the licensees SRT to be free of seismic interaction concerns through the use of current photographs. Please specify the date(s) the photographs were taken.
Response: The photographs were observed on the Browns Ferry Video Tours Omnicast Web Viewer page at the recommendation of BFN Radiation Control personnel in the interest of ALARA considerations. The Drywell web page includes the note Last modified: 5/09/09. There is no date on the photographs.
