regard to the clarification on surrogate inspections, NUREG-1927, Revision 1, notes that surrogate inspections may be acceptable only when substantial operating experience provides a basis for their use. To date, there is currently insufficient operating experience from canister examinations to apply susceptibility assessments and use surrogate data across the ISFSI [independent spent fuel storage installation] fleet, as had originally been proposed in NEI 14-03, Revision 2. In the future, when industry has gained additional experience applying operations-based aging management, it may be appropriate to
