SUPPLEMENTARY INFORMATION:
I. Discussion The NRC is issuing a revision to an existing guide in the NRCs Regulatory Guide series. This series was developed to describe and make available to the public information regarding methods that are acceptable to the NRC staff for implementing 2
specific parts of the agencys regulations, techniques that the NRC staff uses in evaluating specific issues or postulated events, and data that the NRC staff needs in its review of applications for permits and licenses.
Revision 2 of RG 1.178 was issued with a temporary identification of Draft Regulatory Guide, DG-1288. It addresses new information identified since the previous revision of this guide was issued.
II. Additional Information The NRC published a notice of the availability of DG-1288 (ADAMS Accession No. ML20210M047), in the Federal Register on December 14, 2020 (85 FR 80825), for a 30-day public comment period. The public comment period closed on January 13, 2021.
