Office of New Reactors; Final Interim Staff Guidance on Review of 
Evaluation To Address Adverse Flow Effects in Equipment Other Than 
Reactor Internals

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.

ADDRESSES: The NRC ADAMS provides text and image files of NRC's public 
documents. These documents may be accessed through the NRC's Public 
Electronic Reading Room on the Internet at http://www.nrc.gov/reading-rm/adams.html. Persons who do not have access to ADAMS or who encounter
