The Severe Accident Test Station at Oak Ridge National Laboratory uses furnaces to test cladding materials at extreme temperatures. This helps researchers understand why a fuel fails when there is a loss of coolant. The facility is being used to help industry develop new fuels that can survive longer during nuclear accidents and increase the performance of light-water reactors.
