Reactor Facilities

The UMass Lower Research Reactor (UMLRR) houses the nuclear reactor as well as Cobalt gamma irradiation facilities. These sources, through varied facilities, allow for neutron and photon irradiation studies of different irradiation fluences and energies. These facilities have endless uses, but are most commonly used for neutron activation and isotope creation, radiation damage to materials and electronics for testing, detector development, and training evolutions.
