is considered the baseline or “no action” alternative and, as such, involves no value/impact considerations. 3.2 Alternative 2: Update Regulatory Guide 1.124 Under this alternative, the NRC would update Regulatory Guide 1.124 to incorporate revisions documented in the newer edition and addenda of the ASME Code and to delete guidance supplanted by current Code requirements. The benefit of this action is to provide additional assurance to applicants and licensees that the design of Class 1 linear-type component supports is being implemented conservatively. The costs to the NRC would be the one-time, relatively small expense of issuing the revised regulatory guide, and applicants and licensees would incur little or no cost. DG-1168, Page 10 4. Conclusion On the basis of this regulatory analysis, the staff recommends that the NRC revise Regulatory Guide 1.124. The staff concludes that the proposed action will provide additional assurance to applicants and licensees that the design of Class 1 linear-type component supports is being implemented conservatively. BACKFIT ANALYSIS This draft revision to the regulatory guide provides licensees and applicants with updated guidance that the NRC staff considers acceptable for the design of Class 1 linear-type component supports. The application of this regulatory guide is voluntary. Licensees may continue to use the original version of this regulatory guide if they so choose. No backfit, as defined in 10 CFR 50.109, “Backfitting,” is either intended or implied.
