UNITED STATES NUCLEAR REGULATORY COMMISSION May 2, 2018

SUBJECT:

THREE MILE ISLAND NUCLEAR GENERATING STATION - UNIT 1 DESIGN BASES ASSURANCE INSPECTION (TEAM) REPORT 05000289/2018010

Dear Mr. Hanson:

On March 29, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Three Mile Island, Unit 1. On March 29, 2018, the NRC inspectors discussed the results of this inspection with Mr. Ed Callan, Site Vice President, and other members of your staff. The results of this inspection are documented in the enclosed report.

The NRC inspectors did not identify any findings or more-than-minor violations.

This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and the NRCs Public Document Room in accordance with Title 10 of the Code of Federal Regulations (CFR), Part 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely,

/RA/

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring Exelons performance at

Three Mile Island, Unit 1 by conducting a design bases assurance inspection in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.

No findings or more-than-minor violations were identified.

INSPECTION SCOPES

This inspection was conducted using the appropriate portions of the inspection procedure in effect at the beginning of the inspection unless otherwise noted. Currently approved inspection procedures with their attached revision histories are located on the public website at http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html.

Samples were declared complete when the inspection procedure requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter 2515, Light-Water Reactor Inspection Program - Operations Phase. The team reviewed selected procedures and records, observed activities, and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards.

Specifically, the team evaluated these attributes as per 71111.21M, Appendix B, Component Design Review Considerations and 71111.21M, Appendix C, Component Walkdown Considerations.

Components ===

Main article: IP 71111.21
  • DH-V-6B, B Decay Heat Suction Isolation Valve. The team used Appendix B guidance for Valves and Electrical Loads and conducted a walkdown of the equipment.
  • EED-PNL-1F, F 125 Volt DC Distribution Panel. The team used Appendix B guidance for Electrical Loads and Motor Control Centers and conducted a walkdown of the equipment.
  • AFRCCB, Heat Sink Protection System Transfer Relays. The team used Appendix B guidance for Instrumentation and conducted a walkdown of the equipment.
  • EE-MCC-SH-1B, Motor Control Center 1B. The team used Appendix B guidance for Motor Control Centers and Circuit Breakers and Fuses and conducted a walkdown of the equipment.
  • MU-V-0017, Normal Makeup to Reactor Coolant System Control Valve. The team used Appendix B guidance for Valves and conducted a walkdown of the equipment.

Component, Large Early Release Frequency (1 Sample)

  • MS-V-1C, Main Steam Isolation Motor-Operated Valve. The team used Appendix B guidance for Valves, Cables, and Electrical Loads and conducted a walkdown of the equipment.

Permanent Modifications (6 Samples)

  • Replacing Existing Fuel Bridge Speed Controllers
  • Replace Pressurizer Level Transmitter with 3000 PSIG Rated Model
  • Replace Nuclear River Butterfly Valve and Actuator

Operating Experience (3 Samples)

  • 10 CFR Part 21 Notification - Foxboro Power Supply Potential Failures due to Defective Tie Wraps and Holders, dated 7/5/13
  • 10 CFR Part 21, Potential Defect Involving Failure of Westinghouse DB-25 Breakers, dated 5/2/07

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

  • On March 29, 2018, the team presented the Design Bases Assurance Inspection (Teams)results to Mr. Ed Callan, Site Vice President, and other members of Exelon staff.

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring Exelons performance at

Three Mile Island, Unit 1 by conducting a design bases assurance inspection in accordance with

the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for

overseeing the safe operation of commercial nuclear power reactors. Refer to

https://www.nrc.gov/reactors/operating/oversight.html for more information.

No findings or more-than-minor violations were identified.

INSPECTION SCOPES

This inspection was conducted using the appropriate portions of the inspection procedure in

effect at the beginning of the inspection unless otherwise noted. Currently approved inspection

procedures with their attached revision histories are located on the public website at

http://www.nrc.gov/reading-rm/doc-collections/insp-manual/inspection-procedure/index.html.

Samples were declared complete when the inspection procedure requirements most

appropriate to the inspection activity were met consistent with Inspection Manual Chapter 2515,

Light-Water Reactor Inspection Program - Operations Phase. The team reviewed selected

procedures and records, observed activities, and interviewed personnel to assess licensee

performance and compliance with Commission rules and regulations, license conditions, site

procedures, and standards.

Appendix C, Component Walkdown Considerations.

Components (5 Samples)

  • DH-V-6B, B Decay Heat Suction Isolation Valve. The team used Appendix B guidance for

Valves and Electrical Loads and conducted a walkdown of the equipment.

  • EED-PNL-1F, F 125 Volt DC Distribution Panel. The team used Appendix B guidance for

Electrical Loads and Motor Control Centers and conducted a walkdown of the equipment.

  • AFRCCB, Heat Sink Protection System Transfer Relays. The team used Appendix B

guidance for Instrumentation and conducted a walkdown of the equipment.

  • EE-MCC-SH-1B, Motor Control Center 1B. The team used Appendix B guidance for Motor

Control Centers and Circuit Breakers and Fuses and conducted a walkdown of the

equipment.

Appendix B guidance for Valves and conducted a walkdown of the equipment.

Component, Large Early Release Frequency (1 Sample)

  • MS-V-1C, Main Steam Isolation Motor-Operated Valve. The team used Appendix B

guidance for Valves, Cables, and Electrical Loads and conducted a walkdown of the

equipment.

Permanent Modifications (6 Samples)

  • Replacing Existing Fuel Bridge Speed Controllers
  • Replace Pressurizer Level Transmitter with 3000 PSIG Rated Model
  • Replace Nuclear River Butterfly Valve and Actuator

Operating Experience (3 Samples)

  • 10 CFR Part 21 Notification - Foxboro Power Supply Potential Failures due to Defective

Tie Wraps and Holders, dated 7/5/13

Pools, dated 4/7/16

  • 10 CFR Part 21, Potential Defect Involving Failure of Westinghouse DB-25 Breakers,

dated 5/2/07

EXIT MEETINGS AND DEBRIEFS

The inspectors verified no proprietary information was retained or documented in this report.

  • On March 29, 2018, the team presented the Design Bases Assurance Inspection (Teams)

results to Mr. Ed Callan, Site Vice President, and other members of Exelon staff.
