MODERNIZATION PLAN #4 REGULATORY INFRASTRUCTURE PUBLIC MEETING Additional Input from NEI/Industry Preliminary, Unofficial, Partial Poll Results and MP 4Ab Deliverables for 2017 April 13, 2017 1

MP4a Success Then What?

• MP4a Success =

- revised regulation that results in a more predictable, quantifiable, lower risk, scalable, path through the LAR process for safety digital upgrades

• Which Begs the Question:

- If MP4a is successful, what does industry estimate will result in terms of digital safety system upgrades, and specifically LAR submittals?

Future Safety Related Upgrades

• So we took a preliminary poll:

- Very Limited # of Utilities / Units

- Non-committal, Best Guess, Anonymous

- Focused on LAR Submittals

- Some (not all) Included 50.59

- Very Preliminary, Unofficial, Partial Poll

• Over the next 8 years, industry may begin

- LARs for ~10 Protection Systems

- LARs for ~10 Safety Support Systems

- 50.59s for ~20+ Safety Support Systems 3

MP 4Ab Deliverables for 2017

• Develop a DI&C LAR guidance document for licensees. Define the process for using the fundamental design principles. Add a wrapper that:

- Use the fundamental design principles from the white paper

- Define purpose for each section in the document

- Suggest the regulatory findings for each section

- Define the information to be provided in the LAR

- Use standard LAR format from LIC-101

- Consider providing as an appendix to NEI 06-02, Rev. 2

- Industry pilot projects are under formal utility evaluation

• Generate a NEI/NRC project plan, including schedule milestones, that defines how this document will be applied and how pilot lessons learned will be incorporated

• The NRC to generate an endorsement letter for the document, with NRC to endorse in the longer term through the RG process 4
