ot updating the RG for the known issues, in terms of anticipated numbers of licensing and inspection activities over the next several years? For operating reactors, the staff anticipates few licensing activities that will involve the use of RG 1.98, Rev. 0, in the near future. For new reactors, there is a potential for several small modular reactor design certification applications and combined license applications to be submitted in the near future (next 3 to 5 years) that would require the guidance found in RG 1.98, Rev. 0. Since the issues that have been identified through this review represent potential improvements in the document and not deficiencies in the adequacy of the current guidance, there will be little to no impact on internal and external stakeholders if the RG is not revised at this time. - 3 - 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 this RG will take approximately 0.2 FTE of NRC staff time and will require significant coordination between several NRC offices; in particular the Office of Nuclear Reactor Regulation and the Office of New Reactors. It is recommended that revision of this RG be coordinated with the revision of RG 1.24, Rev. 0. Contractor support is not needed to update this RG. 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. Although the NRC does not currently plan a revision to this RG, the NRC plans to continue periodic reviews of this guidance in accordance with agency procedures. The issues identified as part of this review will be considered in future reviews. NOTE: This review was conducted in February 2016
