AGENCY:

Nuclear Regulatory Commission (NRC).

ACTION:

Notice of availability.

SUMMARY:

The NRC is issuing its Final Interim Staff Guidance (ISG) DC/COL-ISG-010 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML092890285). The purpose of this ISG is to modify and provide additional clarity in the guidance for the review of analyses of adverse flow effects in equipment other than reactor internals performed by combined license (COL) and design certification (DC) applicants. This ISG would revise the staff guidance previously issued in March 2007 in the Standard Review Plan (SRP) NUREG 0080, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants,” Section 3.9.2, “Dynamic Testing and Analysis of Systems, Structures, and Components,” Section 3.9.5, “Reactor Pressure Vessel Internals,” and Regulatory Guide 1.20, “Comprehensive Vibration Assessment Program for Reactor Internals During Pre-Operational and Initial Startup Testing.” The NRC staff issues DC/COL-ISGs to facilitate timely implementation of current staff guidance and to facilitate activities associated with review of applications for DCs and COLs by the Office of New Reactors. The NRC staff will also incorporate the approved DC/COL-ISG-010 into the next revision of the SRP and related guidance documents.

Disposition: On March 9, 2009, the NRC staff issued the proposed DC/COL-ISG-010 on “Disposition of Review of Evaluation to Address Adverse Flow Effects in Equipment Other than Reactor Internals,” ADAMS Accession No. ML090510728. There were no comments received on the proposed ISG. Therefore, the guidance is issued as final with only minor editorial changes to the proposed notification as above.
