Nuclear Regulatory Commission.
Notice of Issuance.
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  accumulation in the emergency core cooling, decay heat removal (DHR), and containment spray systems (hereinafter referred to as the “subject systems”). Specifically, the NRC is issuing this GL for two purposes:
(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.
The GL was issued on January 11, 2008.
