Content:
large power reactor license applications anticipated in the near future (next 3 to 5 years). Thus, there is no immediate need for revising the guide at this time to address their licensing. For small modular reactors one application is anticipated in the next two years. 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? Revision of the RG will take 0.5 FTE of NRC staff time to participate in National Research Council meetings, and to perform in-house research on application of risk based methods for liquefaction assessment. 4. Based on the answers to the questions above, what is the recommended staff action for this guide (Reviewed with no issues identified, Reviewed with issues identified for future consideration, Revise, or Withdraw)? Recommend action is to consider RG 1.198 reviewed with issues identified for future consideration, pending release of National Research Council final report in September 2015. 5. If a RG should be revised, provide a conceptual plan and timeframe to accomplish this. Not applicable. NOTE: This review was conducted in September 2014 and reflects the staff’s plans as of that date. These plans are tentative and subject to change.
