Content:
rst draft of the NRC report is scheduled for September 2014 with a final report September 2015. While waiting for the National Research Council to address the case history database, the information in the RG continues to be the most up to date guidance available with the exception of the two sentences from the Discussion Section mentioned above.

What is the impact on internal and external stakeholders of not updating the RG for the known issues, in terms of numbers of licensing and inspection activities? There are no 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
