REPORT DETAILS

REACTOR SAFETY

Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity 1R1 7 Evaluations of Changes, Tests, and Experiments and Permanent Plant Modifications (71111.1 7T)

a. Inspection Scope

Evaluations of Changes, Tests, and Experiments

From May 6, 2013, through May 23 , 2013, the team reviewed eight safety evaluations performed pursuant to Title 10, Code of Federal Regulations (CFR) 50.59 to determine if the evaluations were adequate and that prior NRC approval was obtained as appropriate. The team also reviewed 13 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. The team also consulted Part 9900 of the NRC Inspection Manual, "10 CFR Guidance for 10 CFR 50.59, Changes, Tests, and Experiments

," dated March 2001.

This inspection constituted eight samples of evaluations and 13 samples of screenings as defined in Inspection Procedure (IP) 71111.17-04.

Permanent Plant Modifications

From May 6, 2013, through May 23, 2013, the team reviewed six permanent plant modifications that had been installed in the plant during the last three years. The six modifications reviewed are listed below:

Design Change Package (DCP) 1071694001

, Modification to Isolate Unit 1 Protected Service Water from Turbine Building, Rev. 0 DCP 1072721101

, Reroute Cables out of Fire Area 0014, Ver. 3.0 DCP 1081976501

, Replacement of Upper Shroud Support Assemblies and Tie Rod Nuts, Ver. 2.0 DCP 1092321101

, Coordination Enhancement for 250 VDC Motor Control Center 1R24-S022 Cubicles 4A, 6A, and 9C, Ver. 2.

DCP 1101786501

, Replace Fission Product Monitor Inboard Isolation Valve 1D11-F050, Ver. 1.0 DCP 2039000201

, 4.16kV Breaker Replacement, Ver. 1.1 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 ha d been adequately updated; the test documentation as required by the applicable test programs ha d 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 walk downs of accessible portions of the modifications. Documents reviewed are listed in the Attachment.

This inspection constituted six permanent plant modification samples as defined in IP 71111.17-04.

b. Findings

No findings were identified

.

4OA6 Meetings, Including Exit

On May 23, 2013, the team presented the inspection results to Mr. Dennis Madison 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.
