A research reactor is a type of nuclear reactor primarily used for research, education, and the production of isotopes. Unlike commercial reactors that generate electricity, research reactors focus on experiments in nuclear physics, materials science, and medical applications. They provide a controlled environment for scientists to study nuclear reactions and develop new technologies. These reactors typically operate at lower power levels and can be fueled by various materials, including uranium or plutonium. They are essential for producing radioisotopes used in medical imaging and cancer treatment, as well as for training nuclear engineers and researchers in safe reactor operation.
