DATES:

The effective date of the withdrawal of the RIS 2005-29 and its draft Revision 1, “Anticipated Transients that Could Develop into More Serious Events,” is June 20, 2019.

SUPPLEMENTARY INFORMATION:

The NRC issued RIS 2005-29, “Anticipated Transients that Could Develop into More Serious Events,” (ADAMS Accession No. ML051890212) to notify licensees of the concern identified during reviews of power uprate license amendment requests related to licensing bases of certain licensees failing to demonstrate that anticipated transients will not progress to more serious events. The draft Revision 1 of RIS 2005-29 expanded on this concern and offered staff positions that provided technical guidance for the implementation of NRC regulation (ADAMS Accession No. ML15014A469). The NRC is withdrawing RIS 2005-29, and its draft Revision 1, because the staff identified several regulatory and technical positions within the documents that either required clarification, were no longer supported, or were identified as a new agency position. By memorandum, dated May 15, 2019, the NRC staff provides a summary of the basis for withdrawing RIS 2005-29, and its draft Revision 1 (ADAMS Accession No. ML19121A534).

The NRC's generic communication website (https://www.nrc.gov/​reading-rm/​doc-collections/​gen-comm/​reg-issues/​2005/​) will be updated to reflect RIS 2005-29 as withdrawn.

Dated at Rockville, Maryland, this 12th day of June 2019.

For the Nuclear Regulatory Commission.
