Proposed Generic Communication; Managing Gas Intrusion in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems

The U.S. Nuclear Regulatory Commission (NRC) is proposing to issue a generic letter (GL) to address the issue of gas intrusion into the emergency core cooling, decay heat removal, and containment spray systems (hereinafter referred to as the "subject systems"). Specifically, the NRC is issuing this GL for the following two purposes: (1) to request addressees to submit information demonstrating 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 ML0704001003.
