The MITR is a 5-megawatt research reactor owned and operated by MIT. The MITR has carried out interdisciplinary research in advanced materials and fuel testing for next-generation nuclear systems. One of the many capabilities of the MITR involves the use of in-core loops and the ability to reach temperatures of up to 1,600 degrees centigrade. This allows researchers to replicate nuclear power reactor conditions to study the behavior of advanced materials and fuel designs for next-generation nuclear reactors. The MITR contains a wide range of irradiation facilities that are utilized for various nuclear applications such as neutron transmutation doping, neutron science and neutron capture therapy.
