By letter dated October 27, 2015 (Reference 2), the NRC transmitted final seismic information request tables which identified that Ameren Missouri Callaway Energy Center was to conduct a limited scope Spent Fuel Pool Evaluation.
By Reference 3 Nuclear Energy Institute (NEI) submitted an Electric Power Research Institute (EPRI) report entitled, Seismic Evaluation Guidance Spent Fuel Pool Integrity Evaluation (EPRI 3002009564)
(Reference 4) for NRC review and endorsement. NRC endorsement was provided by Reference 5.
EPRI 3002009564 provides criteria for evaluating the seismic adequacy of a spent fuel pooi (SFP) to the reevaluated ground motion response spectrum (GMRS) hazard levels. Section 4.3 of EPRI 3002009564 lists the parameters to be verified to confirm that the results ofthe report are applicable to Arneren Missouri, and that the Callaway SFP is seismically adequate in accordance with NTTF 2.1 Seismic evaluation criteria.
The attachment to this letter provides the data for Callaway that confirms applicability of the EPRI 3002009564 criteria and confirms that the SFP is seismically adequate in accordance with NTTF 2.1 Seismic evaluation criteria.
This letter contains no new Regulatory Commitments and no revision to existing Regulatory Commitments.

Enclosure To ULNRC-06381 Page 1 of 3 Ameren Missouri Callaway Energy Center Site-Specific Spent Fuel Pool Criteria for Callaway
Enclosure To ULNRC-06381 Page 2 of 3 The 50.54(f) letter (Reference 1) requested that, in conjunction with the response to NTTF Recommendation 2.1, a seismic evaluation be performed for the 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 9 that the GMRS exceeds the SSE and concluded that a SFP evaluation is merited for the Callaway Energy Center. By letter dated 02/08/2017 (Reference 5) the staff determined that EPRI 3002009564 was an acceptable approach for performing SFP evaluations considering the GMRS hazard levels.
The table below lists the criteria from Section 4.3 of EPRI 3002009564 along with data for Callaway that confirms applicability of the EPRI 3002009564 criteria and confirms that the SFP is seismically adequate in accordance with NTTF 2.1 Seismic evaluation criteria.
SFP Criteria from EPRI 3002009564 Site-Specific Data Site Parameters
- 1. The site-specific GMRS should be The Callaway GMRS developed by EPRI and the same as that submitted to the submitted to the NRC in Reference 6 is accepted NRC between March 2014 and July by the NRC in Reference 7.

- 2. Site-specific calculations, performed Site-specific calculations (AMN-12-CALC-001, Rev in accordance with Section 4.1 of 0), performed in accordance with Section 4.1 of EPRI 3002009564 should EPRI 3002009564, demonstrate that the limiting demonstrate that the limiting SFP SFP HCLPF is 1.4g, which exceeds the GMRS HCLPF is greater than the site- 1.35g. Therefore, this criterion is met for Callaway.

As described, no anti-siphoning devices are attached to 2-inch or smaller piping with extremely large extended operators, therefore, this criterion is met for Callaway.
Further, to ensure that there are no potential adverse seismic conditions or interactions, all piping that penetrates the walls of the SFP were walked down by a team consisting of two Seismic Capability Engineers. No adverse seismic interactions were identified and all piping and valves have adequate lateral support.
