Final Interim Staff Guidance: Review of Evaluation To Address Gas
Accumulation Issues in Safety Related Systems
AGENCY: Nuclear Regulatory Commission.
ACTION: Notice of availability.
-----------------------------------------------------------------------
SUMMARY: 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. The staff received comments (ADAMS Accession No.
ML093500086) on the proposed guidance on December 14, 2009. 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. This final
