LR-N 16-0094 Attachment 1 Site-Specific Spent Fuel Pool Criteria for Salem Generating Station, Units 1 and 2

LR-N16-0094 Site-Specific Spent Fuel Pool Criteria for Salem Generating Station, Units 1 and 2 The 50.54(f) letter (Reference 1) 1 requested that, in conjunction with the response to NTTF Recommendation 2.1, a seismic evaluation be made of the Spent Fuel Pool (SFP). More specifically, plants were asked to consider "all seismically induced failures that can lead to draining of the SFP." Such an evaluation would be needed for any plant in which the ground motion response spectrum (GMRS) exceeds the safe shutdown earthquake (SSE) in the 1 to 10 Hz frequency range. The staff confirmed through References 2 and 7 that the GMRS exceeds the SSE and concluded that a SFP evaluation is merited for the Salem Generating Station (SGS), Units 1 and 2. By letter dated March 17, 2016 (Reference 5), the staff determined that EPRI 3002007148 was an acceptable approach for performing SFP evaluations for plants where the peak spectral acceleration (Sa) is less than or equal to 0.8g.

The table below lists the criteria from Section 3.3 of EPRI 3002007148 along with data for SGS Units 1 and 2 that confirms applicability of the EPRI 3002007148 criteria and confirms that the SFP is seismically adequate and can retain adequate water inventory for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> in accordance with NTTF 2.1 seismic evaluation criteria.

SFP Criteria frorn EP~I 3002007148 Site-Specific Data Site Parameters

1. The site-specific GMRS peak Sa at The GMRS peak Sa described in the site-any frequency should be less than specific GMRS submittal (Reference 9) as or equal to 0.8g. accepted by the NRC (Reference 7) is 0.33g, which is ::; 0.8g; therefore, this criterion is met for SGS Units 1 and 2.

Structural Parameters

2. The structure housing the SFP The SFP is housed in the Fuel Handling should be designed using an SSE Building, which is seismically designed to with a peak ground acceleration the site SSE with a PGA of 0.2g. The SGS (PGA) of at least 0.1 g. PGA is greater than 0.1 g; therefore, this criterion is met for SGS Units 1 and 2.

3. The structural load path to the SFP The structural load path from the foundation should consist of some combination to the SFP consists of an 11 ft. thick of reinforced concrete shear wall reinforced concrete mat with reinforced elements, reinforced concrete frame concrete walls varying in width from 4 ft. to elements, post-tensioned concrete 9.6 ft. with a stainless steel liner. The walls elements and/or structural steel go from the top of the foundation mat, 11 ft.

frame elements. below grade to 30 ft. above grade, as shown on drawing 201082, Revision 5, "Salem Nuclear Generating Station No. 1 Unit- Fuel Handling Area Sections F-F & G-G."

Therefore, this criterion is met for SGS Units 1 and 2.

4. The SFP structure should be The SGS SFP structures are included in included in the Civil Inspection PSEG procedure ER-AA-31 0-101, Program performed in accordance "Condition Monitoring of Structures," in with Maintenance Rule. accordance with 10 CFR 50.65, which monitors the performance or condition of structures, systems, or components (SSCs) in a manner sufficient to provide reasonable assurance that these SSCs are capable of fulfilling their intended functions. Therefore, this criterion is met for SGS Units 1 and 2.

Non-Structural Parameters

5. To confirm applicability of the piping Piping attached to the SFP is evaluated to evaluation in Section 3.2 of the SSE as described in UFSAR Section EPRI 3002007148, piping attached 9.1.3.3; therefore, this criterion is met for to the SFP up to the first valve SGS Units 1 and 2.

should have been evaluated for the SSE.

6. Anti-siphoning devices should be As described in UFSAR Section 9.1.3.3, the installed on any piping that could spent fuel pool cooling suction connection lead to siphoning water from the enters near the normal water level so that SFP. In addition, for any cases the pool cannot be gravity-drained. The where active anti-siphoning devices cooling water return lines contain anti-are attached to 2-inch or smaller siphon holes to prevent the possibility of piping and have extremely large gravity draining the pool.

extended operators, the valves should be walked down to confirm As described, anti-siphoning devices are adequate lateral support. installed on all SFP piping that could lead to siphoning; therefore, this criterion is met for SGS Units 1 and 2. There are no anti-siphoning devices attached to 2-inch or smaller piping with extremely large extended operators; therefore, this criterion is met for SGS Units 1 and 2.

7. To confirm applicability of the The Salem SFP has a length of 37ft, a sloshing evaluation in Section 3.2 of width of 28.5 ft. and a depth of 40.5 ft from EPRI 3002007148, the maximum the top of the stainless steel liner at base SFP horizontal dimension (length or elevation 89.5 ft. to the top of the liner at width) should be less than 125 ft, elevation 130 ft. based on Drawing 204836, the SFP depth should be greater Revision 11 .

than 36ft, and the GMRS peak Sa The Salem GMRS maximum Sa in the should be <0.1 g at frequencies frequency range less than or equal to 0.3 Hz equal to or less than 0.3 Hz. is 0.0344g from Reference 6 which is less than 0.1g.

Therefore, these criteria are met for SGS Units 1 and 2.

8. To confirm applicability of the The surface area of the Salem SFP is evaporation loss evaluation in 1054.5 ft 2 , which is greater than 500 ft2; and Section 3.2 of EPRI 3002007148, licensed reactor thermal power for Salem is the SFP surface area should be 3459 MWt per unit which is less than greater than 500 ft 2 and the licensed 4,000 MWt per unit, therefore, these criteria reactor core thermal power should are met for SGS Units 1 and 2.

be less than 4,000 MWt per unit.
