SUBJECT:

ARKANSAS NUCLEAR ONE - DESIGN BASIS ASSURANCE INSPECTION (PROGRAMS) INSPECTION REPORT 05000313/2020011 AND 05000368/2020011

Dear Mr. Dinelli:

On June 26, 2020, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at Arkansas Nuclear One and discussed the results of this inspection with Mr. J. Sullivan, General Manger, Plant Operations, and other members of your staff. The results of this inspection are documented in the enclosed report.

No findings or violations of more than minor significance were identified during this inspection.

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 at the NRC Public Document Room in accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely, Vincent G. Gaddy, Chief Engineering Branch 1 Division of Reactor Safety

SUMMARY

The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting a design basis assurance inspection (programs) inspection at Arkansas Nuclear One, 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.

List of Findings and Violations

No findings or violations of more than minor significance were identified.

Additional Tracking Items

None.

INSPECTION SCOPES

Inspections were conducted using the appropriate portions of the inspection procedures (IPs) in effect at the beginning of the inspection unless otherwise noted. Currently approved IPs 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 IP requirements most appropriate to the inspection activity were met consistent with Inspection Manual Chapter (IMC) 2515, Light-Water Reactor Inspection Program - Operations Phase. The inspectors reviewed selected procedures and records and interviewed personnel to assess licensee performance and compliance with Commission rules and regulations, license conditions, site procedures, and standards. Starting on March 20, 2020, in response to the National Emergency declared by the President of the United States on the public health risks of the coronavirus (COVID-19), regional inspectors were directed to begin telework. The inspection documented below was determined that the objectives and requirements stated in the IP could be completed remotely.

REACTOR SAFETY

71111.21N.02 - Design-Basis Capability of Power-Operated Valves Under 10 CFR 50.55a Requirements POV Review (IP Section 03)

The inspectors:

a. Determined whether the sampled POVs are being tested and maintained in accordance with NRC regulations along with the licensees commitments and/or licensing bases.

Specific Guidance b. Determined whether the sampled POVs are capable of performing their design-basis functions c. Determined whether testing of the sampled POVs is adequate to demonstrate the capability of the POVs to perform their safety functions under design-basis conditions d. Evaluated maintenance activities, including a walkdown of the sampled POVs (if accessible)

(1) CV-1404 - Low Pressure Injection to Reactor Coolant System (Unit 1)
(2) CV-1407 - Borated Water Storage Tank to Low Pressure Injection A suction header (Unit 1)
(3) CV-2691 - Main Steam Isolation valve (unit 1)
(4) CV-3640 - B train discharge to loop II Service Water (Unit 1)
(5) CV-3646 - Service Water system crossover (Unit 1)
(6) CV-3811 - Service Water System (Unit 1)
(7) CV-3840 - Service Water to Pump P34A (Unit 1)

(8)2CV-5103-1 - High Pressure Safety Injection (Unit 2)

(9)2CV-5631-2 - Reactor Building Spray (Unit 2)

(10)2CV-5649-1 - Train A High Pressure Injection outbound sump isolation (Unit 2)

INSPECTION RESULTS

No findings were identified.

EXIT MEETINGS AND DEBRIEFS

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

On June 26, 2020, the inspectors presented the design basis assurance inspection (programs) inspection results to Mr. J. Sullivan, General Manger, Plant Operations, and other members of the licensee staff.
