NUCLEAR REGULATORY COMMISSION

[NRC-2015-0167]


Anticipated Transients That Could Develop Into More Serious 
Events

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft revision to regulatory issue summary; request for 
comment.

-----------------------------------------------------------------------

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is seeking public 
comment on a draft revision 1 to a regulatory issue summary (RIS). 
Revision 1 to the RIS would inform addressees of concerns identified 
during recent license amendment reviews. This draft revision to a RIS 
is addressed to applicants for, and holders of, nuclear power reactor 
licenses, construction permits, standard design approvals, and 
manufacturing licenses, and applicants for standard design 
certifications. This draft revision to a RIS would inform addressees of 
concerns identified during recent reviews of anticipated operational 
occurrences safety analyses of updated final safety analysis reports. 
Revision 1 to RIS 2005-29 will supersede in its entirety RIS 2005-29.

DATES: Submit comments by September 15, 2015. Comments received after 
this date will be considered if it is practical to do so, but the 
Commission is able to ensure consideration only for comments received 
before this date.

II. Background

    The NRC is revising RIS 2005-29 (ML15014A469) to inform addressees 
of concerns identified during recent license amendment reviews. 
Specifically, licensing bases, as documented in final safety analysis 
reports (FSARs), updated FSARs (UFSARs), or design control documents 
(DCDs), failed to demonstrate that anticipated operational occurrences 
(AOOs, Condition II events) would not progress to more serious events 
(Condition III or IV events). The NRC determined that, as a result of 
these problems, these licensees were not in compliance with Part 50, 
Appendix A of Title 10 of the Code of Federal Regulations (10 CFR), 
``General Design Criteria for Nuclear Power Plants,'' specifically, 
general design criteria (GDC) 15, ``Reactor Coolant System Design,'' 
GDC 21, ``Protection System Reliability and Testability,'' and GDC 29, 
``Protection Against Anticipated Operational Occurrences,'' as well as 
10 CFR 50.34(b), ``Final Safety Analysis Report.'' Revision 1 to RIS 
2005-29 supersedes in its entirety RIS 2005-29. The revised RIS would 
be designated as RIS 2005-29, Revision 1. The original version of RIS 
2005-29 was issued on December 14, 2005, and is available in ADAMS for 
viewing (ML051890212).
    The NRC issues RISs to communicate with stakeholders on a broad 
range of matters. This may include providing

[[Page 42560]]

guidance to applicants and licensees on the scope and detail of 
information that should be provided in licensing applications to 
facilitate NRC review.

Proposed Action

    The NRC requests public comments on the NRC-proposed revisions to 
the current RIS. The NRC staff will make a final determination 
regarding issuance of a revised RIS after it considers any public 
comments received in response to this request.

    Dated at Rockville, Maryland, this 13th day of July 2015.

    For the Nuclear Regulatory Commission.

Acting Chief, Generic Communications Branch, Division of Policy and 
Rulemaking, Office of Nuclear Reactor Regulation.
