University of Massachusetts Lowell Radiation Laboratory the conversion from high-enriched Uranium to low-enriched Uranium as a part of anti-terrorism security measures. The used HEU fuel was reportedly shipped to the Savannah River Site. The original shipping date was June 2002 but had been postponed many times. As of present-day the shipments have been made and the reactor is in operation with LEU. University of Massachusetts Lowell Radiation Laboratory The Radiation Laboratory at University of Massachusetts Lowell serves the Department of Applied Physics among others. The laboratory contains a 1 MW pool-type nuclear research reactor (UMLRR) that has been operating since 1974, a 300 kCi Co-60 gamma
