Notice of issuance.
The Nuclear Regulatory Commission (NRC) has issued Bulletin (BL) 2001-01 to all holders of operating licenses for pressurized-water nuclear power reactors, except those who have permanently ceased operations and have certified that fuel has been permanently removed from the reactor vessel. BL 2001-01 addresses the recent discoveries of cracked and leaking reactor pressure vessel head (VHP) nozzles at several pressurized water reactors (PWRs) and the concerns raised about the structural integrity of VHP nozzles throughout the PWR industry. The purpose of the bulletin is to (1) request PWR licensees to provide information related to the structural integrity of the VHP nozzles for their respective facilities, including the extent of VHP nozzle leakage and cracking that has been found to date, the inspections and repairs that have been undertaken to satisfy applicable regulatory requirements, and the basis for concluding that their plans for future inspections will ensure compliance with applicable regulatory requirements, and (2) require PWR licensees to provide to the NRC a written response in accordance with the provisions of 10 CFR 50.54(f). This information request is necessary to permit the assessment of plant-specific compliance with NRC regulations. The information will also be used by the NRC staff to determine the need for and to guide the development of additional regulatory actions to address cracking in VHP nozzles.
The bulletin was issued on August 3, 2001.
