The requirements addressing implementation of Section III Code Cases are contained in 10 CFR 50.55a(b)(4). An applicant’s or a licensee’s voluntary application of an approved Code Case does not constitute backfitting, inasmuch as there is no imposition of a new requirement or new position. No backfitting is intended or approved in connection with the issuance of this guide. DG-1405, Page 53 REFERENCES2 1.
