i-LAMP: Global, Industrywide Learning Aging Management Program for Neutron-Absorber Materials in Spent Fuel Pools

Neutron-absorber materials are used in spent fuel pool (SFP) storage racks to increase storage capacity while maintaining criticality safety margins. Previously, the Electric Power Research Institute (EPRI) proposed a global, industrywide learning aging management program (i-LAMP) as an alternative monitoring program as part of an aging management program. This proposal, along with other EPRI work, was accepted as a concept to close the issued generic letter by the regulator. Since then, EPRI has been working with EPRI-member utilities around the world on data collection. Furthermore, recently, a utility removed two neutron-absorber panels from an operating SFP to meet a regulatory commitment made prior to the i-LAMP proposal. Because of their age and unique history, these panels provided a unique opportunity not only to analyze the conditions of the panels, but also to potentially bound i-LAMP. This paper presents i-LAMP development to date with a focus on BORAL analysis results for these two unique panels, pilot pools as case studies to demonstrate the i-LAMP implementation, and a proposal for a path forward.
