future licensing activities, as to the adequacy of NRC recommendations for testing of design features that the NRC requires by regulation, to ensure the station can implement its emergency and beyond design basis accident procedures to protect the public health and safety. 3. What is an estimation of the level of effort needed to address identified issues in terms of FTE and contract dollars? NRC staff requires approximately 1.6 FTE to revise the RG to recommend testing of both safety and non-safety related busses to verify that no cross-connections or cross- dependencies exist. This testing will help assure that a single event will not adversely impact multiple busses or trains. Another option is to coordinate with the response as it is getting finalized; this option would take more resources such as an additional FTE. 4. Based on the answers to the questions above, what is the staff action for this guide (Reviewed with no issues identified, Reviewed with issues identified for future consideration, Revise, or Withdrawal)? Revise. 5. Provide a conceptual plan and timeframe to address the issues identified during the review. Current status - the RG has been drafted and was sent out for public comment. NEI provided comments to the draft guide and does not want to test electrical separation of non-Cat 1E electrical systems. NRO is currently gathering Operating Experience (OpE) to support the need for testing (ongoing). The unknown is the final requirements in response to Fukushima lessons learned and how they could affect or replace the need for this revision. Incorporating the impact of final requirements in response to Fukushima lessons learned into the RG is estimated to take 3 months. After incorporating the Fukushima lessons learned into the RG we would need to hold internal NRC meetings (NRO, NRR, RES) to get NRC alignment (6 months), then we would have public meetings to explain the NRC proposed revisions, receive additional public comments, and address NEI
