On May 25, 2017, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of Exelon Generation Company, LLC at NRC Headquarters, One White Flint North, 11555 Rockville Pike, Rockville, Maryland. The purpose of the meeting was to discuss a future license amendment request to add mitigating actions to technical specifications with two control room ventilation temperature control system trains inoperable. The meeting notice and agenda, dated May 17, 2017, are available in the Agencywide Documents Access and Management System (ADAMS) at Accession No. ML17137A302. A list of attendees is provided as Enclosure 1.

The licensee presented information (See ADAMS Accession No. ML17132A177) that provided an overview of the future license amendment request.

The NRC staff queried the licensee about the mitigation actions' impact on the control room envelope, the impact on dose to the control room operators, the impact on the control room filtration trains, and the impact of any temporary water supply (water quality) on the affected coolers. The NRC staff stated that these impacts should be addressed in the license amendment request.

The licensee acknowledged that they understood the NRC staff's questions.

Members of the public were in attendance. Public Meeting Feedback forms were not received.
