SUBJECT: MID-CYCLE PERFORMANCE REVIEW AND INSPECTION PLAN - THREE MILE ISLAND NUCLEAR STATION, UNIT 1 (REPORT

05000289/2013006)

Dear Mr. Pacilio:

On August 15, 2013, the U.S. Nuclear Regulatory Commission (NRC) completed its mid-cycle performance review of Three Mile Island Nuclear Station, Unit 1. The NRC reviewed the most recent quarterly performance indicators in addition to inspection results and enforcement actions from July 1, 2012 through June 30, 2013. This letter informs you of the NRC's assessment of your facility during this period and its plans for future inspections at your facility.

The NRC determined the performance at Three Mile Island Unit 1 during the most recent

quarter was within the Regulatory Response Column of the NRC's Reactor Oversight Process (ROP) Action Matrix because of a low to moderate safety significant (White) finding in the Mitigating Systems Cornerstone. Specifically, a White finding associated with the TMI external flood barrier system was identified during the fourth quarter of 2012 as detailed in NRC Inspection Report 05000289/2012005.

On July 26, 2013, your staff notified the NRC of your readiness for it to conduct a supplemental inspection to review the actions taken to address the performance issues. Therefore, in addition to ROP baseline inspections, the NRC plans to conduct a supplemental inspection in accordance with Inspection Procedure 95001, "Supplemental Inspection of One or Two White Inputs in a Strategic Performance Area," beginning on September 9, 2013. The inspection procedure is conducted to provide assurance that the root causes and contributing causes of risk significant performance issues are understood, the extent of condition and cause is identified, and the corrective actions are sufficient to prevent recurrence.

The enclosed inspection plan lists the inspections scheduled through December 31, 2014.

Routine inspections performed by resident inspectors are not included in the inspection plan.

In addition to baseline inspections, the NRC will perform Inspection Procedure (IP) 71003,

"Post-Approval Site Inspection for License Renewal," and Temporary Instruction (TI) 2515/182, "Review of the Implementation of the Industry Initiative to Control Degradation of Underground Piping and Tanks." The inspections listed during the last nine months of the inspection plan are tentative and may be revised at the end-of-cycle performance review. The NRC provides the inspection plan to allow for the resolution of any scheduling conflicts and personnel availability issues. The NRC will contact you as soon as possi ble to discuss changes to the inspection plan should circumstances warrant any changes. This inspection plan does not include security-related inspections, which will be sent via separate, non-publicly available correspondence.

In accordance with Title 10 of the Code of Federal Regulations (10 CFR) Section 2.390 of the NRC's "Rules of Practice," a copy of this letter will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of the NRC's Agencywide Documents Access and Management system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Please contact Gordon Hunegs at (610)337-5046 with any questions you have regarding this letter.

Sincerely,

/RA/ Darrell J. Roberts, Director Division of Reactor Projects
