NUCLEAR REGULATORY COMMISSION

[NRC-2009-0110]


Interim Staff Guidance on Disposition of Review of Evaluation To 
Address Adverse Flow Effects in Equipment Other Than Reactor Internals

AGENCY: Nuclear Regulatory Commission.

ACTION: Solicitation of public comment.

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

SUMMARY: The NRC is soliciting public comment on its Proposed Interim 
Staff Guidance (ISG) DC/COL-ISG-010 (Agencywide Documents Access and 
Management System (ADAMS)

[[Page 11138]]

Accession No. ML090510728). 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.

DATES: Comments must be filed no later than 30 days from the date of 
publication of this notice in the Federal Register. Comments received
