r does the NRC staff intend to use the guidance to affect the issue finality of an approval under 10 CFR Part 52, “Licenses, certifications, and approvals for nuclear power plants.” Any changes to this trial regulatory guide prior to staff’s adoption of a final regulatory position will not be considered to be backfits as defined in 10 CFR 50.109. This trial use regulatory guide also does not constitute forward fitting as that term is described in MD 8.4. RG 1.247, Page 67 REFERENCES7 1.
