SUBJECT: NOTIFICATION OF SURRY POWER STATION DESIGN BASES ASSURANCE
INSPECTION - U.S. NUCLEAR REGULATORY COMMISSION INSPECTION
REPORT 05000280/2020010 AND 05000281/2020010
Dear Mr. Stoddard:
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC)
Region II staff will conduct a Design Bases Assurance Inspection (DBAI) at your Surry Power
Station during the weeks of September 14-18, 2020, and September 28-October 2, 2020.
Mr. Theo Fanelli, a Senior Reactor Inspector from the NRCs Region II office, will lead the
inspection team. The inspection will be conducted in accordance with Inspection Procedure 71111.21M, Design Bases Assurance Inspection (Teams), dated December 8, 2016 (ADAMS
The inspection will evaluate the capability of components that have been modified and risk-
significant/low-margin components to function as designed and to support proper system
operation. The inspection will also include a review of selected operator actions, operating
experience, and modifications.
During a telephone conversation on June 15, 2020, with Mr. Steve Newman, we confirmed
arrangements for an information-gathering site visit and the two-week onsite inspection. The
schedule is as follows:
- Information-gathering visit: Week of August 24, 2020
- Onsite weeks: Weeks of September 14 and September 28, 2020
The purpose of the information-gathering visit is to meet with members of your staff to identify
components that have been modified, risk-significant components and operator actions.
Information and documentation needed to support the inspection will also be identified.
Mr. Andy Rosebrook, a Region II Senior Risk Analyst, will support Mr. Fanelli during the
information-gathering visit to review probabilistic risk assessment data and identify components
to be examined during the inspection. Additionally, during the first onsite week, time will be
needed on the plant-referenced simulator in order to facilitate the development of operator
action-based scenarios.

The enclosure lists documents that will be needed prior to the information-gathering visit.
Please provide the referenced information to the Region II Office by Friday, August 14, 2020.
Additional documents will be requested following the information-gathering visit. The inspectors
will try to minimize your administrative burden by specifically identifying only those documents
required for inspection preparation. The additional information will be needed in the Region II
office by Wednesday, September 2, 2020, to support the inspection teams preparation week.
During the information-gathering trip, Mr. Fanelli will also discuss the following inspection
support administrative details: (1) availability of knowledgeable plant engineering and licensing
personnel to serve as points of contact during the inspection; (2) method of tracking inspector
requests during the inspection; (3) licensee computer access; (4) working space; (5)
arrangements for site access; and (6) other applicable information.
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," 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). ADAMS is accessible
from the NRC website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic
Reading Room).
Thank you for your cooperation in this matter. If you have any questions, regarding the
information requested or the inspection, please contact Mr. Fanelli at 404-997-4433 or contact
me at 404-997-4506.
Sincerely,
