The MIT Nuclear Reactor has been in commission for 54 years. “NRL has provided a safe and reliable neutron source and the infrastructure to facilitate use of that source. During its long and distinguished history, the NRL has supported educational training and cutting-edge research in the areas of nuclear fission engineering, material science, radiation effects in biology and medicine, neutron physics, geochemistry, and environmental studies.”
The nuclear reactor does not produce energy. It is for research purposes only. It also does not do any research into information that relates to weaponry. The reactor allows for student interaction, a great benefit to MIT and other students who want a hands on experience in regards to nuclear reactors.
The reactor there today is the second generation model, referred to as the MITR-II. In 1973, the MITR-I was shut down to allow conversion to the MITR-II, which offered a higher neutron flux level. The current reactor is a heavy-water reflected, light-water cooled and moderated nuclear reactor that utilizes flat, plate-type, finned, aluminum-clad fuel elements.
There are many safety precautions at the nuclear reactor lab- background checks, signatures at the reception desk, radiation measurements in multiple forms, full-time operator, pressurized chamber, metal and concrete containers to hold radioactive material, just to name some of the many ways the lab ensures the safety of its employees and the people and systems that could be affected. There are many fail safes to ensure no radioactive material gets released from the lab. The reactor is in a special containment building, so if anything were to happen, the material would be kept from leaving the lab.
One thing I found interesting during the visit was that the lab helped make radioactive “seeds” for cancer treatment. I think it is great they are using the resources to contribute positively to the community.
I was not aware until this class that a nuclear reactor was so close to where I live. The trip reinforced my thoughts that nuclear reactors can be very safe when the proper precautions are taken.
