A 5 cm diameter bronze medallion from the Bettis Atomic Laboratory in a 11 cm by 8 cm paper holder. The Bettis laboratory is a US-government laboratory, operated under contract by Westinghouse. It is located in Pittsburgh, Pennsylvania, and developed Oak Ridge National Laboratory’s original design of the pressurized water reactor (PWR) for operational naval use. It built the nuclear propulsion plants for the first U.S. nuclear submarines and surface ships. Some early tests of these reactor fuels were done at the NRX reactor is Chalk River and it is assumed the medallion was presented to CRNL staff at that time.
