NRC, "Response to Request for Additional Information Regarding Braidwood TORMIS Amendment Request," dated July 9, 2018 In Reference 1, Exelon Generation Company, LLC (EGC) requested an amendment to Renewed Facility Operating License Nos. NPF-72 and NPF-77 for Braidwood Station, Units 1 and 2. In Reference 2, EGC responded to requested additional information to support the review of the subject License Amendment Request. A of Reference 1, "Summary of Regulatory Commitments" contains one listed Commitment that "Tornado missile protection will be installed on the Unit 1 and Unit 2 RWST hatches."

The additional information provided in this submittal does not affect the conclusion that the proposed license amendment does not involve a significant hazards consideration . This additional information also does not affect the conclusion that neither an environmental impact statement nor an environmental assessment need be prepared in support of the proposed amendment.
