The Advanced Test Reactor (ATR) at the Idaho National Laboratory (INL) supports research and testing of materials for use in large-scale and prototype reactors. Previous analysis by BEA raised potential concerns with the primary heat exchanger supports under a design earthquake. SGH evaluated the seismic performance of the primary heat exchanger supports and designed necessary upgrades.
