J. Pacher UNITED STATES NUCLEAR REGULATORY COMMISSION

REGION I

2100 RENAISSANCE BLVD., SUITE 100 KING OF PRUSSIA, PA 19406-2713 June 19, 2014 Mr. Michael Senior Vice President, Exelon Generation Company, LLC President and Chief Nuclear Officer, Exelon Nuclear 4300 Winfield Rd.

Warrenville, IL 60555 SUBJECT: THREE MILE ISLAND NUCLEAR STATION, UNIT 1 - NRC CYBER SECURITY INSPECTION REPORT 05000289/2014405

Dear Mr. Pacilio:

On May 29, 2014, the U.S. Nuclear Regulatory Commission (NRC) completed a follow-up inspection to an unresolved item (URI) from a previous cyber security inspection at your Three Mile Island Station, Unit 1 (TMI). The URI was documented in NRC inspection report (IR)

05000289/2013404. The results of the follow-up and closure of the URI were discussed with Mr. Joe Dullinger and other members of your staff on May 29, 2014, and are documented in this IR.

The inspection examined activities conducted under your license as they relate to cyber security and compliance with the Commissions rules and regulations and with the conditions of your license. The inspector reviewed selected procedures and records, observed activities, and interviewed personnel.

No NRC-identified findings were identified during this inspection.

However, the inspector documented a licensee-identified violation which was determined to be of very low safety significance in this report. The NRC is treating this violation as a non-cited violation (NCV) consistent with Section 2.3.2.a of the Enforcement Policy.

If you contest the violation or significance of this NCV, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC resident inspector at the Three Mile Island Nuclear Station, Unit 1.

Enclosure contains Sensitive Unclassified Non-Safeguards Information.

When separated from enclosure, the transmittal document is decontrolled. In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 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 NRC's Agencywide Document 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). However, the material enclosed herewith contains Security-Related Information in accordance with 10 CFR 2.390(d)(1) and its disclosure to unauthorized individuals could present a security vulnerability. Therefore, the material in the enclosure will not be made available electronically for public inspection in the NRC Public Document Room or from the PARS component of NRC's ADAMS. If you choose to provide a response and Security-Related Information is necessary to provide an acceptable response, please mark your entire response "Security-Related Information - Withhold from public disclosure under 10 CFR 2.390" in accordance with 10 CFR 2.390(d)(1) and follow the instructions for withholding in 10 CFR 2.390 (b)(1). In accordance with 10 CFR 2.390(b)(1)(ii), the NRC is waiving the affidavit requirements for your response.

Sincerely,

/RA/
