Dear Ms. Lav; In response to Reference 3 request for additional information, Framatome provides the NRC with the following to support a License Amendment Request to extend the currently approved methodology for determining the minimum margin pf sub-criticality to include enrichments up to 20wt.% 235 U. is a revision to the documentation of Framatome's SCALE 6.2.2 code validation efforts to support this request. After the NRC approves this request, Framatome will add attachment 1 to the reference section of Chapter 5 of SNM-1227 and will send an updated copy of this chapter to the NRC within six months of making the change. documents the supporting detailed calculations of Attachment 1 and is provided to assist in the review. documents the responses to the NRC Request for Additional Information.

Framatome continues to commit to only use SCALE 6.2.2/KENO-VI and ENDF/B-Vl 1.1 Continuous Energy (CE) cross sections to support fuel fabrication process applications involving uranium enrichments greater than 5.0 wt.% 235U; if a newer version of SCALE/KENO-VI is adopted in the future, then that version of code will be validated using the methodology described in Attachment 1, which will be updated accordingly.

No changes in actual possession limits or any other license conditions are being requested at this time.
