Description: Argonne National Laboratory in collaboration with Idaho National Laboratory (INL) studies how to better recycle spent nuclear fuel. Samples from INL's Advanced Test Reactor (ATR) core are sent to Argonne's ATLAS particle accelerator for analysis to learn the characteristics of the nuclear material. INL's Advanced Test Reactor has a unique serpentine fuel arrangement, which allows researchers to simultaneously test materials under varied conditions. This image shows the characteristic blue glow, which is due to Cherenkov radiation. It is emitted when a charged particle such as an electron passes through the cooling water at a speed faster than the speed of light in the water. The ATR’s unique four-leaf-clover core design provides nine main test spaces at 250 MWTH.
