SUBJECT:

COLUMBIA GENERATING STATION - DESIGN BASES INSPECTION (PROGRAMS) (INSPECTION REPORT 05000397/2016008)

Dear Mr. Reddemann:

On May 12, 2016, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Columbia Generating Station. The NRC inspectors discussed the results of this inspection with you and other members of your staff. The 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, Public Inspections, Exemptions, Requests for Withholding, of the NRC's "Rules of Practice and Procedure," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS)

component of the NRC's Agencywide Documents 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).

Sincerely,

/RA/

1R21 Component Design Basis Inspection

a. Inspection Scope

The inspection team performed a pilot inspection conducted as outlined in NRC Inspection Procedure (IP) 71111.21N, Attachment 1, Environmental Qualification under 10 CFR 50.49, Programs, Processes, and Procedures. The team assessed Columbia Generating Stations implementation of the environmental qualification program as required by 10 CFR 50.49, Environmental qualification of electric equipment important to safety for nuclear power plants. The team evaluated whether Columbia Generating Station staff properly maintained the environmental qualification of electrical equipment important to safety throughout plant life, established and maintained required environmental qualification documentation records, and implemented an effective corrective action program to identify and correct environmental qualification-related deficiencies.

The inspection included review of environmental qualification program procedures, component environmental qualification files, environmental qualification test records, equipment maintenance and operating history, maintenance and operating procedures, vendor documents, design documents, and calculations. The team interviewed program owners, engineers, maintenance staff, and warehouse staff. The team performed in-plant walkdowns (where accessible) to verify equipment was installed as described in Columbia Generating Stations environmental qualification component documentation files and that the components were installed in their tested configuration. Additionally, the team performed in-plant walkdowns to determine whether equipment surrounding the components could fail in a manner that could prevent the safety functions of the components and to verify that components located in areas susceptible to a high energy line break were properly evaluated for operation in a harsh environment. The team reviewed and inspected the storage of replacement parts and associated procurement records to verify environmental qualification parts approved for installation in the plant were properly identified and controlled, and that storage and environmental conditions did not adversely affect the components qualified lives. Documents reviewed for this inspection are listed in the attachment.

The inspection procedure requires the team to select 6 to 10 components to assess the adequacy of the environmental qualification program. The team selected 9 components for this inspection. Component samples selected for this inspection are listed below:

• CEP-SPV-1A, Containment Exhaust Purge Solenoid Pilot Valve CEP-SPV-1A.

• E-CONN X102A, SOLISTRAND #34130 Parallel Splice Connectors, for Thermocouple and RTD Penetrations. Off of Mid-Plane in Drywell, Within Primary Containment.

• HPCS-MO-1, Motor Operator for the High Pressure Core Spray Motor Operated Valve 1.

• HPCS-FIS-6, High Pressure Core Spray Discharge Header Minimum Flow Indicator Switch for High Pressure Core Spray Pump HPCS-P-1.

• HPCS-M-P/1, 3000HP/373A Drive Motor for High Pressure Core Spray Pump HPCS-P-1.

• LD-TE-4A, Reactor Core Isolation Cooling Equipment Area Leak Detection Temperature Element.

• RCIC-DPIS-13A, Reactor Core Isolation Cooling Steam Supply High Flow Indicator Switch.

• RCIC-M-V/13, Reactor Core Isolation Cooling Injection Valve Motor for the Valve Operator.

• RCIC-PS-9A, Reactor Core Isolation Cooling Exhaust Pressure High Trip Switch.

b. Findings

No findings were identified.

4OA2 Problem Identification and Resolution

a. Inspection Scope

The team reviewed a sample of issues which were previously identified and entered into the corrective action program. The team reviewed these issues to verify an appropriate threshold for identifying issues and to evaluate the effectiveness of corrective actions.

In addition, condition reports written on issues identified during the inspection were reviewed to verify adequate problem identification and incorporation of the problem into the corrective action program. The specific condition reports that were sampled and reviewed by the team are listed in the attachment.

b. Findings

No findings were identified.

4OA6 Meetings, Including Exit

Exit Meeting Summary

On May 12, 2016, the inspectors presented the final inspection results to Mr. M. Reddemann, Chief Executive Officer, and other members of the licensee staff. The licensee acknowledged the issues presented. The licensee confirmed that any proprietary information reviewed by the inspectors had been returned or destroyed.
