The Purdue University Reactor Number One (PUR-1) is a research reactor in West Lafayette, Indiana, United States. It is used primarily for teaching purposes in Purdue University's School of Nuclear Engineering. Built in 1962, the PUR-1 is the only nuclear reactor operating in the US state of Indiana. It was the second reactor installed in Indiana, and was the first critical reactor, after a sub-critical reactor was installed at Valparaiso University in 1958.[2]
