Dear Ms. Lav;

Via Reference 2, Framatome informed the NRC that Framatome planned to submit a License Amendment Request to extend the currently approved methodology for determining the minimum margin of sub-criticality to include enrichments up to 20 wt.% 235U. Framatome hereby requests the NRC approve extending this methodology to include enrichments up to 20 wt.%

235U.

documents 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.

Framatome continues to commit to only use SCALE 6.2.2/KENO-VI and ENDF/B-VI1.1 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.
