National Research Universal Reactor

The National Research Universal (NRU) Reactor was a large scientific facility in Canada designed to produce medical isotopes, research materials, and support nuclear science. It operated by using nuclear fission to generate heat, which in turn produced neutrons—tiny particles essential for experiments and isotope production. It played a crucial role in providing isotopes for medical imaging and treatments worldwide. The reactor was known for its high neutron output and long operational life before shutting down in 2018 for safety and modernization reasons. Its work significantly contributed to medicine, science, and industry.
