The Oregon State University Radiation Center (OSURC) is a research facility that houses a nuclear reactor
Nuclear reactor
A nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. Most commonly they are used for generating electricity and for the propulsion of ships. Usually heat from nuclear fission is passed to a working fluid , which runs through turbines that power either ship's...

The OSU Radiation center supported 126 projects in 2000 with 69% directly involving use of the OSTR. Contracts supporting these projects in 2000 totaled $3 million.

The mission statement of the center is

To serve as the campus wide teaching, research, and service facility for programs involving the use of ionizing radiation and radioactive materials.
