Dominion Energy SLR Digital I&C Project Update NRC ISG-06 Meeting February 10, 2021 Robert Atkinson Senior Generation Project Manager - SLR 1

Digital I&C Vision

• Vision

- Full replacement of major I&C systems at Surry and North Anna Power Stations

• Phased approach

• Digital team -> Operations, I&C, Engineering, Management

• Surry will lead -> North Anna to lag

- Standardize on a common SR and NSR Platform

- Upgrade the MCR to soft control system

• Build a second Simulator

- Upgrade Technical Specifications/UFSAR 2

Drivers for the Digital I&C Project

• Drivers for making the changes

• Obsolescence and sustainability

• Single point vulnerabilities

• I&C Technicians

• Engineering

• Goal is to reduce O&M costs

• Labor reduction

• Harvesting person-hours

• Increased future Operator proficiency

• Automation and Enhancements 3

Benefits

• Benefits

- Maintenance

• Condition based

• Reduced training

- Engineering

• Diagnostics and fault detection

• Plant/system performance and health monitoring

• Measurement precision improvements

- Operations - enhanced Operator interface

• Automated control functions

• Condition-based alarms

• Human Factor Engineered MCR changes

- Simplified Operator training 4

Benchmarking

• Key takeaways

- Must include MCR in upgrades

- Leverage automation

• Fewer Operator person-hours needed

• Much less expensive up front

- Organizational changes

• Digital team established

- Training - train the Operators, I&C, Engineering and Management

- Must develop a comprehensive digital life-cycle plan 5
