II. Discussion

Exelon is the holder of Renewed Facility Operating License No. DPR-50 for TMI-1. The license provides, among other things, that the facility is subject to all rules, regulations, and orders of the NRC now or hereafter in effect. The facility consists of one pressurized-water reactor located in Dauphin County, Pennsylvania. By letter dated June 20, 2017 (ADAMS Accession No. ML17171A151), the licensee submitted Certification of Permanent Cessation of Power Operations for TMI-1. In this letter, Exelon notified the NRC of its intent to permanently cease operations at TMI-1 no later than September 30, 2019.

On April 5, 2019, Exelon submitted the PSDAR for TMI-1, in accordance with § 50.82(a)(4)(i) of title 10 of the Code of Federal Regulations (ADAMS Accession No. ML19095A041). The PSDAR includes a description of the planned decommissioning activities, a proposed schedule for their accomplishment, the expected decommissioning and spent fuel management costs, and a discussion that provides the basis for concluding that the environmental impacts associated with the site-specific decommissioning activities will be bounded by appropriate, previously issued generic and plant-specific environmental impact statements. In separate letters, Exelon submitted its Site Specific Decommissioning Cost Estimate and Spent Fuel Management Plan for TMI-1 on April 5, 2019 (ADAMS Accession Nos. ML19095A010 and ML19095A009, respectively).Start Printed Page 33094
