[External_Sender] Modernization Plan (MP) #1 - Protection Against Common Cause Failure (CCF)

Paul, In support of the Integrated Action Plan (IAP) to Modernize DI&C Regulatory Infrastructure, in particular Modernization Plan (MP) #1B, I want to inform you that the NEI Digital I&C working group will no longer continue the development of NEI 16-16, Guidance for Addressing Digital Common Cause Failure.

Currently the NEI DI&C working group is developing a new NEI technical document to meet the overall objective of MP #1, which is Protection Against Common Cause Failure (CCF). The NEI DI&C working group is confident that our new approach will appropriately address CCF in digital system design from both a technical and regulatory perspective.

I will inform you when the NEI DI&C working group has developed a draft of the new NEI technical document. At that point I expect the NRC and NEI can begin planning for a public meeting to discuss the technical and regulatory contents of the draft document.

Please let me know if you have any questions or concerns,

Regards, STEPHEN J.
