Agenda: To provide a basis for reclassifying the completion of final design of the reactor flange tool stand (RFT stand) as a COL item.

- Review of fuel locations where qualification is required.

- Review of fuel design inputs, core plate motions, and fuel analysis performed by Framatome.

- Potential RFT stand design capable of meeting seismic requirements:

- Description* of bounding seismic analysis performed on the RFT design.

- Core Plate motions for conceptual RFT designs and bay locations ISRS. *

Perform a site specific analysis that demonstrates during.

an SSE: - The s~ismic category 1 RFT stand is retained in position in the refueling pool. - The lower RPV is retained* in the RFT stand. - The RFT stand is structurally qualified in accordance with SC 1 criteria.

COL Implementation -Applicant Actions (cont)

Fuel margins to limits are established using the more demanding of the following two scenarios:
- site specific core plate motions in the RFT are enveloped by the design basis core plate motions for the RPV in the RFT stand, OR

- the core plate motions for the assembled NPM in the operating bays at the site are enveloped by the design basis core plate motions with the assembled NPM installed.in the operating bays 16 PM-1218-63892-NP Revision: O Copyright 2018 by NuScale Power, LLC. Ttm1µ1c11e ff-. uuuu-L 11 Lt-ru I r-"+
