Dear Mr. Halnon:
On August 19 - September 30, 2020, the U.S. Nuclear Regulatory Commission (NRC)
conducted an inspection of the Three Mile Island Nuclear Station Unit 2 (TMI-2). An on-site inspection was performed August 19, 2020. Additional inspection activities (in office reviews)
were conducted remotely as a consequence of the COVID-19 public health emergency (PHE)
during the inspection period. The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations, and the conditions of your license. The inspection consisted of plant walk-downs by the inspector, interviews with personnel, and a review of procedures and records. The results of the inspection were discussed with you and Trevor Orth, Site Decommissioning Director, Exelon Generating Company (Exelon), and other members of Exelon management and staff on September 30, 2020, at the conclusion of the inspection and are described in the enclosed report. No findings of safety significance were identified.
In accordance with 10 CFR 2.390 of the NRCs "Rules of Practice," a copy of this letter, its enclosure(s), and your response, if any, will be made available electronically for public inspection in the NRC Public Document Room or from the NRC document system (ADAMS),
accessible from the NRC website at http://www.nrc.gov/reading-rm/adams.html. To the extent possible, your response, if any, should not include any personal privacy, proprietary, or safeguards information so that it can be made available to the Public without redaction.
Current NRC regulations and guidance are included on the NRC's website at www.nrc.gov; select Radioactive Waste; Decommissioning of Nuclear Facilities; then Regulations, Guidance and Communications. The current Enforcement Policy is included on the NRC's website at www.nrc.gov; select About NRC, Organizations & Functions; Office of Enforcement; Enforcement documents; then Enforcement Policy (Under 'Related Information').

EXECUTIVE SUMMARY
GPU Nuclear, Inc. (GPUN)
Three Mile Island Station, Unit 2 (TMI-2)
NRC Inspection Report No. 05000320/2020002 A routine announced safety inspection was conducted on August 19 - September 30, 2020, of TMI-2. An on-site inspection was performed August 19, 2020. Additional inspection activities were conducted remotely during the inspection period as a consequence of the COVID-19 public health emergency (PHE). The inspection included a review of radiological controls programs, maintenance, plant support activities, management oversight, and the corrective action program (CAP) while in Post-Defueling Monitored Storage (PDMS) status. The inspection consisted of interviews with GPUN and Exelon Generating Company (Exelon) personnel, a review of procedures and records, and plant walk-downs. There are currently no ongoing decommissioning activities being conducted at TMI-2. The NRC's program for overseeing the safe operation of a shut-down nuclear power reactor is described in Inspection Manual Chapter (IMC) 2561, "Decommissioning Power Reactor Inspection Program."
Based on the results of this inspection, no findings of safety significance were identified.

REPORT DETAILS
1.0 Background GPUN retains the license for TMI-2 and maintains the facility. GPUN is a wholly-owned subsidiary of FirstEnergy Corp. As part of the sale of TMI-2, GPUN entered into an agreement with AmerGen (now Exelon) to conduct services for TMI-2. Under this agreement, Exelon provides all services, materials, and equipment required to maintain TMI-2 in PDMS status. Services provided by Exelon include maintenance, surveillance testing, and implementation of the activities required in the Safety Analysis Report (SAR), Technical Specification (TS), and the GPUN PDMS Quality Assurance (QA)
Plan.
In December 1993, TMI-2 received a possession-only license from the NRC to enter PDMS. Currently, TMI-2 is in long-term monitored storage. In June 2013, GPUN submitted to the NRC a Post-Shutdown Decommissioning Activities Report (PSDAR)
(ADAMS No. ML13190A366) pursuant to 10 Code of Federal Regulations (CFR)50.82(a)(4). GPUN submitted Revision 1 of their PSDAR in November 2013 (ADAMS No. ML13323A497) and Revision 2 in December 2015 (ML15338A222).
The NRC's program for overseeing the safe operation of a shut-down nuclear power reactor is described in IMC 2561.
2.0 Post-Defueling Monitored Storage Performance and Status Review
a. Inspection Scope
[Inspection Procedures (IPs) 36801, 37801, 40801, 62801, 71801, 83750, 84750, 86750 A routine announced safety inspection was conducted on August 19 - September 30, 2020 of TMI-2. The inspection consisted of interviews with GPUN and Exelon personnel, a review of procedures and records, and plant walk-downs. The inspector reviewed the PDMS program as outlined in the PDMS SAR, TS, and PSDAR. The inspection included a review of radiological programs, maintenance, plant support activities, management oversight, and the CAP while in PDMS status. The inspector also assessed the material condition of TMI-2 facilities during plant tours of the auxiliary building, fuel handling building, and the control building.
The inspector reviewed activities, components, and documentation associated with the following PDMS programs: occupational exposure, radioactive effluent control, and site radiological environmental monitoring program (REMP). The inspector reviewed the offsite dose calculation manual, the radioactive effluent release permits, the annual REMP report, the groundwater monitoring program, and the annual effluent report, which included a summary of the radioactive waste management and transportation programs.
The inspector reviewed surveillances of containment isolation, unfiltered leak rate from containment, and containment air locks as required by the TS. The inspector reviewed the CAP and audit reports associated with TMI-2 to determine if issues were being appropriately identified, assessed, and reviewed and that corrective actions were being appropriately implemented.
b. Observations and Findings
The inspector confirmed that there were no design changes since the last inspection requiring 50.59 evaluations. The inspector confirmed that no dismantlement or decommissioning activities were performed since the previous inspection and confirmed that all required reporting submittals were completed in accordance with regulatory requirements. The inspector also verified that the maintenance and surveillance program for systems and components had been conducted in accordance with the established site procedures.
The inspector reviewed the annual radiological effluent, REMP reports and supporting analyses and determined that all calculated doses were well below regulatory dose criteria of 10 CFR 50, Appendix I. The inspector noted that there were no radioactive waste shipments from TMI-2 during calendar year 2019.
The inspector determined that scheduled QA audits were conducted timely, and findings or issues identified by these reviews were entered into the stations CAP as Action Reports (AR). Based on the review of ARs, the inspector noted that required corrective actions appear to be appropriately and timely implemented.
c. Conclusions
Based on the results of this inspection, no findings of safety significance were identified.
