NUCLEAR REGULATORY COMMISSION

[NRC-2009-0494]


Office of New Reactors; Proposed Interim Staff Guidance; Review 
of Evaluation To Address Gas Accumulation Issues in Safety Related 
Systems

AGENCY: Nuclear Regulatory Commission (NRC).

ACTION: Solicitation of public comment.

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

SUMMARY: The NRC staff is soliciting public comment on its proposed 
Interim Staff Guidance (ISG) DC/COL-ISG-019 (Agencywide Documents 
Access and Management System (ADAMS) Accession No. ML092360375). 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) Sections 5.4.7, ``Residual Heat Removal System,'' 6.3 ``Emergency 
Core Cooling System,'' and 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.

DATES: Comments must be filed no later than 30 days from the date of 
publication of this notice in the Federal Register. Comments received 
after this date will be considered, if it is practical to do so, but 
the Commission is able to ensure consideration only for comments 
received on or before this date.

ADDRESSES: You may submit comments by any one of the following methods. 
Please include Docket ID NRC-2009-0494 in the subject line of your

including any information in your submission that you do not want to be 
publicly disclosed.
    The NRC requests that any party soliciting or aggregating comments 
received from other persons for submission to the NRC inform those
