- Core Functions
- The Massachusetts Institute of Technology’s Nuclear Reactor Laboratory (MIT NRL) operates the MITR-II 6MW research reactor on the MIT main campus. The NRL specializes in development of new irradiation experiments, materials and instrumentation testing in extreme environments, utilizing irradiation to probe the properties of materials, and the analysis of irradiated specimens.
- Unique Functions
- MITR provides in-core and out-of-core thermal and fast neutron irradiation of nuclear fuels and material experiments, in addition to gamma irradiation using spent fuel. We offer in-core flow loops at LWR conditions that can use BWR or PWR chemistry. And we can perform in-core flow loop irradiation testing for high temp gas reactor materials loop up to 1600C.
- Hotwork Facilities
- Hot cells and hot sample prep facilities are available in containment building and restricted area.
- Support Equipment
- Polar crane with 20T and 3T capability
- Radiological Limit
