SUPPLEMENTARY INFORMATION:

The NRC has granted the request, dated June 17, 2019 (ADAMS Accession No. ML19169A031), of Exelon Generation Company, LLC (the licensee) to withdraw its application, dated December 14, 2018 (ADAMS Accession No. ML18351A006), for proposed amendment to Renewed Facility Operating License No. DPR-50 for the Three Mile Island Nuclear Station, Unit 1, located in Dauphin County, Pennsylvania.

The amendment would have revised Technical Specification 6.8.5 “Reactor Building Leakage Rate Testing Program.” The amendment would have allowed for a one-cycle extension to the 10-year frequency of the Three Mile Island Nuclear Station, Unit 1, containment leakage rate test (i.e., ILRT or Type A test). The proposed change would have permitted the existing ILRT to be extended from 10 years to 11.75 years. This extension would have moved the performance of the next ILRT from the scheduled fall 2019 refueling outage to the fall 2021 refueling outage.

Exelon's December 14, 2018, request was noticed in the Federal Register on March 26, 2019 (84 FR 11338).
