Dear Ms. Venkataraman,
As requested by U.S. Nuclear Regulatory Commission correspondence dated November 9, 2017, the FirstEnergy Nuclear Operating Company and applicable contractors have reviewed the draft safety evaluation (SE) for proposed amendments regarding transition to NFPA 805, Performance-Based Standard for Fire Protection for Light Water Reactor Electric Generating Plants. Based on this review, the draft SE does not contain any proprietary or sensitive unclassified non-safeguards information. Specific items related to the factual accuracy and completeness of the SE were identified and are listed in the attached document for your consideration.
Respectfully, Phil H.
