Researchers use one-of-a-kind expertise and capabilities to test fuels of tomorrow
At the Idaho National Laboratory Hot Fuel Examination Facility, containment box operator Jake Maupin moves a manipulator arm into position around a pencil-thin nuclear fuel rod. He is preparing for a procedure that he and his colleagues have practiced repeatedly in anticipation of this moment in the hot cell.

Alpha radiolysis experiments have been performed on NpO2 that contains sorbed moisture. A high dose rate to the sample was achieved by spiking it with ~7000 ppm 244Cm during preparation. Pressure monitoring of sample containers showed that a low, steady-state pressure plateau is reached. This plateau indicates a situation in which the forward reaction (i.e., radiolysis of water) is equal to the back reaction (i.e., the reformation of H2O). In this technical note, a simple kinetic model that can be used for predicting steady-state pressures under practical conditions is described.
