UNITED STATES NUCLEAR REGULATORY COMMISSION ber 28, 2015

SUBJECT:

H. B. ROBINSON STEAM ELECTRIC PLANT - NRC EVALUATION OF CHANGES, TESTS, AND EXPERIMENTS AND PERMANENT PLANT MODIFICATIONS INSPECTION REPORT 05000261/2015007

Dear Mr. Glover:

On November 19, 2015, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your H. B. Robinson Steam Electric Plant, Unit 2. On November 19, 2015, the NRC inspectors discussed the results of this inspection with you and other members of your staff. Inspectors documented the results of this inspection in the enclosed inspection report.

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 2.390 of the NRCs Rules of Practice, a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publically Available Records component of NRCs document system (ADAMS). ADAMS is accessible from the NRC Website 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 No.: 50-261 License No.: DPR-23

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

a. Inspection Scope

Evaluations of Changes, Tests Experiments: The team reviewed eight safety evaluations performed pursuant to Title 10, Code of Federal Regulations (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 15 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; and

• 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, Revision 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 10 permanent plant modifications that had been installed in the plant during the last three years. The modifications reviewed are listed below:

• DCHG 0000275044, EDG A Voltage Regulator Replacement child EC#1

• DCHG 0000277390, Replace TE-410, TE-420 & TE-430 Cold leg RTDs Revision 2:

Revise Torque Values for the subject RTD PATEL Conduit Seal Assembly Interface Fitting

• DCHG 0000280186, Replace Existing A1 and B1 Battery Chargers child EC#1 to master EC 77389 Replace Battery Charger A1

• DCHG 0000280351, Relocate RPS System BFD/NBFD Relays, RF0-29 Modification child EC for Rack 61 Implementation (Master EC 68034)

• DCHG 0000284282, Replace RHR-744A AND RHR-744B Motors

• DCHG 0000291633, Diesel Fire Pump Engine Replacement

• DCHG 0000292104, NUS Replacement for Hagan Function Generators LTAM RNP-10-359 LRPF 428011

• DCHG 0000272331, Replace EDG FO Day Tank Solenoid Valves

• DCHG 0000279462, Replace CST Level Transmitter

• DCHG 0000300624, Replace Thermal Overloads for SI-864A 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; and

• 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.
