Research Reactor

The OSURR is an open pool, MTR-type research reactor that is a unique asset to nuclear engineering research and education at OSU and in the State of Ohio, and it is utilized for instructional, research, and service activities. It has multiple vertical dry tubes and beam ports that serve as irradiation facilities, and the OSURR is licensed to operate at thermal powers (no electricity is produced) up to a maximum of 500 kilowatts. At the maximum power, the neutron flux in the available irradiation dry tubes are on the order of 1012-1013 n/cm2/s.

The OSURR is used for a wide range of nuclear-related research endeavors, including evaluation of material elemental constituents using neutron activation analysis (NAA) and neutron depth profiling (NDP); evaluation of radiation damage to electronic components and other materials, such as optical fibers and optical fiber-based sensors; evaluation of neutron and gamma-ray radiation sensitive detector performance; isotope production; and biomedical experiments.  

The OSURR is not constrained by a fixed duty-cycle, allowing great flexibility in scheduling research and education activities. The reactor has multiple irradiation locations that allow instrumented experiments, enabling in-situ experiment measurements and real-time monitoring during irradiations. The non-fixed duty cycle enables researchers to perform experiments utilizing varying reactor power levels and even power transients. 

A number of experimental facilities converge at the reactor core, which allows simultaneous performance of multiple experiments. These facilities include: 

  1. CIF vertical dry tube 
  2. AIF and PIF vertical dry tubes 
  3. Moveable vertical dry tubes 
  4. Beam facility 
  5. Pneumatic facility 
  6. Thermal column
