| 2011-24344 | Final Interim Staff Guidance: Review of Evaluation To Address Gas Accumulation Issues in Safety Related Systems | Notice | The U.S. Nuclear Regulatory Commission (NRC) staff is issuing its Final Interim Staff Guidance (ISG) DC/COL-ISG-019 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML111110572). The purpose of this ISG is to clarify the NRC staff guidance to address issues of gas accumulation in safety related systems. This ISG revises and updates the guidance provided to the staff in Standard Review Plan (SRP) Section 5.4.7, "Residual Heat Removal System," Section 6.3, "Emergency Core Cooling System," and Section 6.5.2, "Containment Spray System" of NUREG-0800, "Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants," March 2007. 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 design certifications and combined licenses by the Office of New Reactors. The NRC staff intends to incorporate the final approved DC/COL-ISG-019 into the next revision of the SRP and related guidance documents. Disposition: On November 12, 2009 (74 FR 58323), the NRC staff issued proposed DC/COL-ISG-019 on "Review of Evaluation to Address Gas Accumulation Issues in Safety Related Systems," ADAMS Accession No. ML092360375.

These comments were further discussed in a public meeting held at the NRC on January 20, 2010, and in a conference call on July 9, 2010.
