Subject:

Notification of Deviation from BWRVIP-38 Guidance River Bend Station - Unit 1 License No. NPF-47 Docket No. 50-458 RBF1-11-0155

Dear Sir or Madam:

This letter provides notification of a deviation from the Boiling Water Reactor Vessel and Internals Project (BWRVIP) guidelines for River Bend Station (RBS). This is a deviation from the performance of inspections in accordance with the examination schedules of BWRVIP-38, "BWR Vessel and Internals Project, BWR Shroud Support Inspection and Flaw Evaluation Guideline," (EPRI Report 108823, September 1997).

This deviation is a one-time extension of up to 5% (6 months) to the 10-year interval for the ultrasonic inspection strategy of the H8 and H9 shroud support welds specified under BWRVIP-38, Section 3.3. RBS is extending the time between inspections of the core shroud support welds, H8 and H9, from the 10 years recommended under BWRVIP-38 to up to as much as 10 years and 6 months to align the examinations with current outage schedules and reduce the overall radiation exposure incurred to satisfy plant commitments for work behind the biological shield. As currently scheduled, the time between inspections will be approximately 10 years and 3.5 months.

This deviation from the BWRVIP guidelines has been reviewed and approved in accordance with Entergy procedures and NEI 03-08 guidance. This is a notification of a deviation only, and no action is being requested from NRC.
