The National Institute of Standards and Technology (NIST) Center for Neutron Research (NCNR) in Gaithersburg, Maryland, experienced a minor radiation leak on February 3, 2021, leading to the reactor’s immediate shutdown. While no employees received dangerous doses of radiation, the incident prompted a thorough investigation into the cause and subsequent corrective actions.
The NCNR reactor, a smaller-scale version compared to nuclear power reactors, plays a crucial role in various scientific fields. Its primary function is to generate neutrons for research purposes, contributing to advancements in areas such as pharmaceuticals, material science, and data storage. Unlike nuclear power reactors that produce thousands of megawatts of thermal power, the NCNR reactor generates a significantly lower 20 megawatts.
Following the detection of elevated radiation levels, ten trained radiation workers were exposed and received elevated, but safe, doses. They underwent immediate decontamination procedures and were cleared to return home the same evening. Subsequent screenings confirmed that no employee received doses exceeding the established limits for radiation workers. While exact dosage figures are still being analyzed, NIST officials have assured the public that the release was well below regulatory limits and posed no threat to the surrounding community.
The radiation levels within the facility have since returned to normal, with external levels remaining well within safety standards. The Nuclear Regulatory Commission expressed satisfaction with NIST’s response to the incident, confirming the safety of the public in the vicinity.
NIST is currently developing a plan to safely assess the reactor’s condition and conduct a thorough investigation to identify the root cause of the leak. Once determined, appropriate corrective measures will be implemented. The duration of the reactor shutdown and its impact on ongoing research projects remain uncertain at this time.

In conclusion, the minor radiation leak at the NIST Center for Neutron Research resulted in a temporary shutdown and a thorough safety review. While the incident raised concerns, swift action and adherence to safety protocols ensured the well-being of personnel and the surrounding community. The facility will remain offline until the cause is identified and rectified, allowing research activities to resume safely.
