NUCLEAR REGULATORY COMMISSION

Final Interim Staff Guidance DC/COL-ISG-10: Review of Evaluation 
To Address Adverse Flow Effects in Equipment Other Than Reactor 
Internals

AGENCY: Nuclear Regulatory Commission.

ACTION: Interim staff guidance; withdrawal.

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

SUMMARY: The Nuclear Regulatory Commission (NRC) is withdrawing its 
Final Interim Staff Guidance (ISG) DC/COL-ISG-10, ``Review of 
Evaluation to Address Adverse Flow Effects in Equipment Other than 
Reactor Internals.'' This ISG served to supplement the guidance 
provided to the staff in Sections 3.9.2, ``Dynamic Testing and Analysis 
of Systems, Structures, and Components,'' and 3.9.5, ``Reactor Pressure 
Vessel Internals,'' of NUREG-0800, ``Standard Review Plan for the 
Review of Safety Analysis Reports for Nuclear Power Plants: LWR 
Edition,'' concerning the review of probabilistic risk assessment 
information and severe accident assessment submitted to support design 
certification (DC) and combined license (COL) applications. The NRC 
staff issues ISG to facilitate timely implementation of current staff 
guidance and to facilitate activities associated with review of 
applications for DC and COLs by the Office of New Reactors. The NRC 
staff incorporated the approved DC/COL-ISG into Revision 4 to Sections 
3.9.2 and 3.9.5 of NUREG-0800 dated March 2017. With the issuance of 
Revision 4 to Sections 3.9.2 and 3.9.5 of NUREG-0800, the staff has 
determined that DC/COL-ISG-10 is no longer necessary and should be 
withdrawn.

DATES: The date of the withdrawal of Final Interim Staff Guidance DC/
COL-ISG-10 is May 17, 2019.

SUPPLEMENTARY INFORMATION: On November 3, 2009, as noticed in the 
Federal Register (74 FR 58323), the staff issued its Final Interim 
Staff Guidance, DC/COL-ISG-10, ``Review of Evaluation to Address 
Adverse Flow Effects in Equipment Other than Reactor Internals'' (ADAMS 
Accession No. ML092890285). This document is being withdrawn because on 
March 6, 2017, the staff issued Revision 4 to Sections 3.9.2 and 3.9.5 
of NUREG-0800 (ADAMS Accession No. ML16133A418), incorporating the 
guidance of DC/COL-ISG-10 and, therefore, superseding it. Therefore, as 
of the date of this notice, DC/COL-ISG-10 is withdrawn.

    Dated at Rockville, Maryland, this 14th day of May 2019.

    For the Nuclear Regulatory Commission.
Jennivine K. Rankin,
Acting Chief, Licensing Branch 3, Division of Licensing, Siting, and 
Environmental Analysis, Office of New Reactors.
