Mr. DavidPresident and Chief Nuclear Officer Virginia Electric & Power Company Innsbrook Technical Center 5000 Dominion Blvd. Glen Allen, VA 23060-6711

SUBJECT: SURRY POWER STATION - U.S. NUCLEAR REGUALTORY COMMISSION EVALUATION OF CHANGES, TESTS, AND EXPERIMENTS AND PERMANENT PLANT MODIFICATIONS INSPECTION REPORT 05000280/2015007 AND 05000281/2015007

Dear Mr. Heacock:

On October 1, 2015, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Surry Power Station, Units 1 and 2, and discussed the results of this inspection with Mr. R. Simmons and other members of your staff. Inspectors documented the results of this inspection in the enclosed inspection report (IR).

The NRC inspectors did not identify any findings or violations of more than minor significance. In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390, "Public inspections, exemptions, requests for withholding" of the NRC's "Agency Rules of Practice and Procedure," a copy of this letter, and its Enclosure, 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 Documents Access and Management System (ADAMS); accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,/RA/

Jonathan H. Bartley, Chief Engineering Branch 1 Division of Reactor Safety Docket Nos. 50-280 and 50-281 License Nos. DPR-32 and DPR-37

SUMMARY

Inspection Report (IR) 05000280/2015007 and 05000281/2015007; 9/14/2015 - 10/1/2015; Surry Power Station, Units 1 and 2; Evaluations of Changes, Tests, and Experiments and Permanent Plant Modifications

This report covers a 2-week onsite inspection by one senior reactor inspector, two reactor inspectors, and one technical reviewer. No findings or violations were identified. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 5.

1R17 Evaluations of Changes, Tests, Experiments and Permanent Plant Modifications

a. Inspection Scope

Evaluations of Changes, Tests, and Experiments: The team reviewed six safety evaluations performed pursuant to Title 10 of the Code of Federal Regulations (10 CFR) 50.59, "Changes, tests, and experiments," to determine if the evaluations were adequate, and that prior NRC approval was obtained as appropriate. The team also reviewed 16 screenings where licensee personnel had determined that a 10 CFR 50.59 evaluation was not necessary. The team reviewed these documents to determine if:

  • the changes, tests, or experiments performed were evaluated in accordance with 10 CFR 50.59, and that sufficient documentation existed to confirm that a license amendment was not required
  • the safety issues requiring the changes, tests, or experiments were resolved
  • the licensee conclusions for evaluations of changes, tests, or experiments were correct and consistent with 10 CFR 50.59
  • the design and licensing basis documentation used to support the change was updated to reflect the change The team used, in part, Nuclear Energy Institute (NEI) 96-07, "Guidelines for 10 CFR 50.59 Implementation," Rev. 1, to determine acceptability of the completed evaluations and screenings. The NEI document was endorsed by the NRC in Regulatory Guide 1.187, "Guidance for Implementation of 10 CFR 50.59, Changes, Tests, and Experiments," dated November 2000. Permanent Plant Modifications: The team reviewed six permanent plant modifications that had been installed in the plant during the last 3 years. The modifications reviewed are listed below:
  • DCP 06-045, Replace SW Carbon Steel Piping With Copper-Nickel Pipe Class or Coated Piping/Surry/ Unit 1
  • DC SU-12-00012, Replace EDG Governor Booster Pump Suction Line Units 1 & 2
  • DC SU-10-01041, High Head Safety Injection MOV Valve Pressure Locking Modifications/S/1&2
  • DC SU-11-01108, Set Point Change For Emergency Service Water Temperature Switches
  • DC SU-11-01049, Loop Stop MOV Stem Connection MOD/S/1&2 The modifications were selected based upon risk significance, safety significance, and complexity. The team reviewed the modifications selected to determine if:
  • the supporting design and licensing basis documentation was updated
  • the changes were in accordance with the specified design requirements
  • the procedures and training plans affected by the modification had been adequately updated
  • the test documentation, as required by the applicable test programs, had been updated
  • post-modification testing adequately verified system operability and/or functionality The team also used applicable industry standards to evaluate acceptability of the modifications and performed walkdowns of accessible portions of the modifications. Documents reviewed are listed in the Attachment.

b. Findings

No findings were identified.

4OA6 Meetings, Including Exit

On October 1, 2015, the team presented inspection results to Mr. Simmons and other members of the licensee's staff. The team verified that no proprietary information was retained by the inspectors, or documented in this report.
