SUBJECT:
REQUEST FOR SEISMIC DESIGN ISSUES CLOSURE PLAN FOR THE NUSCALE POWER, LLC During a public meeting on August 17, 2017, NuScale Power, LLC (NuScale) informed the U.S.
Nuclear Regulatory Commission (NRC) that it would need over 60 days to respond to several request for additional information (RAI) questions related to seismic design issues. Some of the RAIs responses are anticipated in late 2018 (Enclosure 1). In order to successfully complete Phase 2 for Sections 3.7.2 Seismic System Analysis, 3.8.4 Other Seismic Category I Structures, and 3.8.5 Foundations, the NRC staff requests that NuScale provide a closure plan for resolving the technical issues raised in these RAI questions. The plan should include the approach NuScale will take to respond to the RAI questions, as well as the actions to be performed for closing and completing each response. Also, the plan should include a schedule for submitting the final responses and identifying where markups of the FSAR will be provided.
The NRC staff will review NuScales closure plan to determine whether its strategy for planned RAI-responses would meet NRC requirements and support the proposed schedule.
If you have any questions, please contact Gregory Cranston at (301) 415-0546 or via e-mail at Gregory.Cranston@nrc.gov.
Respectfully,
/RA/
