Interim staff guidance; withdrawal.
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3.9.2 and 3.9.5 of NUREG-0800, the staff has determined that DC/COL-ISG-10 is no longer necessary and should be withdrawn.
The date of the withdrawal of Final Interim Staff Guidance DC/COL-ISG-10 is May 17, 2019.

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 This document is being withdrawn because on March 6, 2017, the staff issued Revision 4 to Sections 3.9.2 and 3.9.5 of NUREG-0800 (ADAMS Accession No. ML16133A418), incorporating the guidance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 Therefore, as of the date of this notice, DC/COL-ISG-10 is withdrawn.
