Content:
olders of not updating the RG for the known issues, in terms of anticipated numbers of licensing and inspection activities over the next several years? This guide is applicable to BWR and PWR concrete containment buildings. There are no new applications for these designs anticipated in the near future (approximately the next three to five years), and there is only one operating plant that uses grouted post tensioned tendons. Therefore there is no immediate impact if the guide is not revised at this time. 3. What is an estimate of the level of effort needed to address identified issues in terms of full-time equivalent (FTE) and contractor resources? Approximately 0.25 FTE of the NRC staff time would be required to complete a revision/update of the RG 1.107. 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 Withdraw)? Reviewed with issues identified for future consideration. 5. Provide a conceptual plan and timeframe to address the issues identified during the review. The NRC staff plans to complete a detailed evaluation of the updated endorsed codes and standards, including a determination of the need to revise RG 1.107, in approximately two years’ time. NOTE: This review was conducted in August, 2016 and reflects the staff’s plans as of that date. These plans are tentative and are subject to change.
