A research reactor built in 1962 that was converted to digital control and operation in 2019 is aiding the development of advanced nuclear reactors, such as small modular reactors and microreactors. An article published by Purdue University describes how Purdue University Reactor Number One (PUR-1), currently the only facility to be licensed for a fully digital safety and control system by the Nuclear Regulatory Commission, is being used to perform “first-of-a-kind experiments that are unique to the nuclear sector.”
