NUCLEAR REGULATORY COMMISSION


Managing Gas Accumulation in Emergency Core Cooling, Decay Heat 
Removal, and Containment Spray Systems

AGENCY: Nuclear Regulatory Commission.

ACTION: Notice of Issuance.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) has issued 
Generic Letter (GL) 2008-01 all holders of operating licenses for 
nuclear power reactors, except those who have permanently ceased 
operations and have certified that fuel has been permanently removed 
from the reactor vessel. The NRC is issuing this GL to address the 
issue of gas \1\ accumulation in the emergency core cooling, decay heat 
removal (DHR),\2\ and containment spray systems (hereinafter referred 
to as the ``subject systems''). Specifically, the NRC is issuing this 
GL for two purposes:
---------------------------------------------------------------------------

    \1\ ``Gas'' as used here includes air, nitrogen, hydrogen, water 
vapor, or any other void that is not filled with liquid water.
    \2\ DHR, residual heat removal (RHR), and shutdown cooling are 
common names for systems used to cool the reactor coolant system 
(RCS) during some phases of shutdown operation. In this GL, the NRC 
staff generally uses ``DHR.''
---------------------------------------------------------------------------

    (1) To request addressees to submit information to demonstrate that 
the subject systems are in compliance with the current licensing and 
design bases and applicable regulatory requirements, and that suitable 
design, operational, and testing control measures are in place for 
maintaining this compliance, and
    (2) To collect the requested information to determine if additional 
regulatory action is required.
    This Federal Register notice is available through the NRC's 
Agencywide Documents Access and Management System (ADAMS) under 
Accession Number ML080160231.

DATES: The GL was issued on January 11, 2008.

ADDRESSES: Not applicable.
