SUBJECT:

ANNUAL ASSESSMENT LETTER FOR THREE MILE ISLAND STATION, UNIT 1 (REPORT 05000289/2018006)

Dear Mr. Hanson,

The NRC has completed its end-of-cycle performance assessment of Three Mile Island Station, Unit 1, reviewing performance indicators (PIs), inspection results, and enforcement actions from January 1, 2018, through December 31, 2018. This letter informs you of the NRCs assessment of your facility during this period and its plans for future inspections at your facility. The NRC concluded that overall performance at your facility preserved public health and safety.

The NRC determined the performance at Three Mile Island Station, Unit 1, during the most recent quarter was within the Licensee Response Column (Column 1) of the NRCs Reactor Oversight Process (ROP) Action Matrix in Inspection Manual Chapter 0305, Operating Reactor Assessment Program, because all inspection findings had very low safety significance (i.e., Green), and all PIs were within the expected range (i.e., Green). Therefore, the NRC plans to conduct ROP baseline inspections at Three Mile Island Station, Unit 1.

The enclosed inspection plan lists the inspections scheduled through December 31, 2020. This updated inspection plan now includes planned security inspections which were formerly transmitted under separate correspondence. The NRC provides the inspection plan to allow for the resolution of any scheduling conflicts and personnel availability issues. Routine inspections performed by resident inspectors are not included in the inspection plan. You should be aware that the agency is pursuing potential changes to the ROP, including changes to engineering inspections (SECY-18-0113, Recommendations for Modifying the Reactor Oversight Process Engineering Inspections). Should these changes to the ROP be implemented, the engineering and other region-based inspections are subject to change in scope, as well as schedule, beginning in January 2020. In a letter (ML17171A151) dated June 20, 2017, pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 50.82(a)(1)(i), you notified the NRC of your intent to permanently cease power operations at Three Mile Island Station, Unit 1 no later than September 30, 2019. Therefore, the inspection schedule is tentative and may be revised. Once you formally notify the NRC in accordance with 10 CFR 50.82(a)(1)(ii) that Three Mile Island Station, Unit 1 is permanently shutdown and that all the nuclear fuel has been removed from the reactor vessel, then Three Mile Island Station, Unit 1 will transition from NRC IMC 0305, Operating Reactor Assessment Program, and IMC 2515, Light-Water Reactor Inspection Program - Operations Phase, to IMC 2561, Decommissioning Power Reactor Inspection Program. The NRC will contact you as soon as possible to discuss changes to the inspection plan should circumstances warrant any changes. Finally, the Reactor Oversight Process and Inspection Program provides inherent flexibility to permit inspection sampling adjustments using IMC 2515, Appendix G, Baseline Inspection Guidance for Power Reactors Preparing for Transition to Decommissioning Phase. These adjustments are be made in order to better inform our assessment of performance during this unique period of operations prior to permanent plant shutdown. In addition, the NRC will be implementing quarterly assessment reviews, consistent with the guidance contained in IMC 0305, Operating Reactor Assessment Program, in order to more closely monitor and review overall plant activities to assure that there are no issues emerging that might indicate a decline in focus on the safe operation of the facility.

In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRCs Website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Please contact me at 610-337-5205 with any questions you have regarding this letter.

Sincerely,

/RA/
