Subject:

Diversity NUREG/OR After reviewing Draft NUREG, "Diversity Strategies for Nuclear Power Plant Instrumentation and Control &C Systems,"

VC Summer has two comments.

1. System Interactions needs to address Cyber Security Controls that may be implemented as part of 10CFR 73.54 and NUREG/CR 6847 for Common Cause Failures (CCF).
2. There is no reference to DI&C ISG-02 [Diversity and Defense-in-Depth (D3)].
