The Radiation Laboratory at the University of Massachusetts Lowell serves the Department of Applied Physics among others. The laboratory contains the University of Massachusetts Lowell Research Reactor (UMLRR), a 1 MW pool-type research reactor[1] that has been operating since 1974, along with a 300 kCi Co-60 gamma ray source and a 5.5 MeV Van de Graaff accelerator.

Reactor
editThe first startup was on January 2, 1975.[2] A budget for the reactor is not provided by the university or the state; funding comes from customer irradiations, grants, and the United States Department of Energy.[3][4]
Conversion to LEU
editThe UMass Lowell reactor has been one of the many research reactors to make the conversion from high-enriched uranium (HEU) to low-enriched uranium (LEU) as a part of anti-terrorism security measures.[5] 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.
Neutron Irradiation Capabilities
editNeutron irradiation facilities at the UMLRR include: 1x 8-inch beam port, 2x 6-inch beam ports, in-core radiation baskets & flux trap, thermal column, and fast neutron irradiator (FNI).[6]
