1 l COMMISSIONER MERRIFIELD'S COMMENTS ON SECY 99-192 l
l approve the staff's request to publish the proposed changes to 10 CFR 50, Appendix K as described in SECY 99-192.
In reviewing this paper, I have benefitted from the comments provided by the ACRS in its letter dated July 22,1999. I have also reviewed the staff's response dated August 18,1999. I accept the staff's assurance that, as a matter of course during power uprate reviews, it reviews the impact of power level assumptions on all relevant safety analyses, including the non-LOCA analyses which may be limiting at certain plants or types of plants.
