Cancellation of Proposed Generic Communication Control Rod Insertion Problems

The Nuclear Regulatory Commission (NRC) is canceling a bulletin supplement that requests addressees to take actions to ensure the continued operability of the control rods. The proposed bulletin supplement was endorsed by the Committee to Review Generic Requirements (CRGR) and subsequently published in the Federal Register for public comment (62 FR 27629, May 20, 1997). The NRC considered comments received from interested parties in the final evaluation of the proposed bulletin supplement. Furthermore, the staff has received substantial additional data and data analysis from fuel manufacturers and owner's groups regarding the incomplete rod insertion (IRI) issue. Licensees, as well as fuel manufacturers and owner's groups, have informed the NRC of efforts to eliminate the IRI problem, including redesign of the fuel assemblies and improved core management. The staff expects these efforts to be successful, and the staff will follow this issue by monitoring plant operations through normal inspections and reporting activities.
