Concerns about aging degradation of PWR reactor pressure vessel internals have become a high priority as nuclear units approach license renewal. Renewal applications must consider the effects of aging in order to meet conditions defined in the NRC's Generic Aging Lessons Learned Report. In response, the MRP's Reactor Internals Focus Group (RI-FG) has prepared draft inspection and evaluation guidelines for managing the effects of aging degradation in PWR internals. The guidelines, to be issued under the NEI 03-08 Materials Initiative, will include developing an Aging Management Program (AMP) and inspection plan for PWR internals. Structural Integrity Associates, Inc. (SI), working closely with MRP RI-FG, has beta-tested the draft guidelines for several PWRs. SI provides technical support for plants considering aging management reviews for license renewal, or for plants developing AMPs to manage the effects of aging in PWR internals.
