NOTE 2: Periodically VY will have access to the lower plenum welds due to maintenance activities not related to the inspection recommendations in the BWRVIP guidelines.

In such cases, VY will perform a visual inspection of the shroud support leg welds to the extent practical. When inspection tooling and methodologies are developed that allows access to the lower plenum without disassembly beyond normal refueling activities, shroud support leg welds will be inspected with an appropriate NDE method. Results of inspections will be used to determine a re-inspection schedule. VY will adopt future inspection methods and schedules as they are developed and included into BWRVIP-38 and approved by the NRC staff.
