DRAFT APPROACH FOR A NEW REGULATORY GUIDANCE INFRASTRUCTURE FOR DIGITAL INSTRUMENTATION AND CONTROL (I&C)

Category 2 Public Meeting April 28, 2020 1

• Meeting Purpose

• Background

• Draft Approach for a New I&C Regulatory Guidance Infrastructure

• Highest NRC Priority Areas

• Next Steps 2

Presentation Outline

3 Meeting Purpose

• Discuss with the Nuclear Energy Institute (NEI) and industry, the NRCs draft approach for achieving a simpler and more effective I&C regulatory infrastructure.

• Obtain feedback from NEI and industry including which areas are of higher priority.

4 Background

• NRC continues to strive to improve the clarity and cohesiveness of the I&C regulatory infrastructure.

• While the NRC staff has focused to date on tactical improvements, it is now transitioning to modernizing and streamlining the overall I&C regulatory infrastructure.

• As a first step, the NRC staff developed a draft approach for streamlining the I&C Regulatory Guide (RG) infrastructure framework.

See attachment to meeting notice

6 Highest NRC Priority Areas

• RG 1.153 - I&C Safety Criteria o Update to endorse IEEE 603-2018

• RG 1.152 - Criteria for Computers o Update to endorse IEEE 7-4.3.2-2016 and retire ISG-04 for digital communication systems

• RG 1.168 - Software V&V o

Assess graded-approach alternatives for the specified software integrity level guidance in IEEE-1012-2016 o

Assess the feasibility of consolidating criteria in RGs 1.168 through 1.173 for a more efficient demonstration of software quality

7 Next Steps

• Receive industry feedback on the draft I&C regulatory guidance infrastructure and highest priority areas.

• Finalize the new I&C RG infrastructure framework.

• Implement plans for updating I&C regulatory guidance.
