moved to storage and later to a burial ground. The fuel in the dump tank was slated to be reprocessed. About 60 samples of equipment and material were taken for detailed analysis and examination. Metallographic, activation, visual, stereophotographic, and leak tests were performed. Follow-up After the ARE operated, the ANP project moved on with plans to build a larger experiment, the 60 MW Aircraft Reactor Test (ART). The ART was to be a NaF-ZrF4-UF4-fueled, Be-moderated, Be-reflected core with sodium metal as the reflector coolant and NaK as the secondary coolant. Its shield was made of lead and borated water. Building 7503 at ORNL was significantly re-excavated in an extension project including new deep excavations to accommodate the ART, but the program was cancelled before the new experiment was performed. The building and facilities later went on to house the Molten Salt Reactor Experiment. See also Aircraft Nuclear Propulsion Nuclear-powered aircraft References Nuclear propulsion
