Nuclear Reactor Laboratory


The Ohio State University Nuclear Reactor Laboratory (NRL) is an interdisciplinary research facility within the university's College of Engineering. The NRL features The Ohio State University Research Reactor (OSURR), a professional gamma-ray spectroscopy system, multiple gamma-ray irradiators, and other irradiation facilities and radiation measurement equipment.

The NRL provides irradiation and measurement services in support of student and faculty research, student education, and as a service to industry. In addition, the laboratory provides instructional services in the form of student laboratory sessions and tours that support the university's Nuclear Engineering Program. Services are scheduled during regular business hours and are charged to users on a cost-recovery basis. For inquiries regarding costs for services, please email reactor@osu.edu





    • Gamma Irradiators ( Instrument )

      1) A Co-60 underwater irradiator that provides gamma rays of 1173 keV and 1332 keV for in-situ irradiation of devices. Samples and experiments are irradiated in a 6"-diameter dry tube. Due to the design of the loading elevator, the usable diameter for an experimental setup in the 6"-diameter tube is ~ 4". The usable height is limited by the falloff in the flux profile and the dose rate. 2)A benchtop irradiator is also available for low dose-rate testing.The space for sample irradiations is ~ 7.75" in length by 3.75" in diameter. 3)A spot irradiator makes use of a source collimator to enable in-situ radiation-damage testing of an electronic device while minimizing the dose received by other devices nearby on the test board.

    • Gamma Sources ( Instrument )

      Cs-137, button sources (cesium 137, button source)

    • Gamma-ray Spectroscopy System ( Instrument )

      Three (3) high purity germanium detectors (HPGe) housed in copper-lined lead caves to reduce background, that are used to identify and quantify radioisotopes in samples.

    • Neutron Sources ( Instrument )

      PuBe and AmBe sources (PuBe, AmBe, plutonium beryllium, americium beryllium)

    • Research Reactor ( Instrument )

      The Ohio State University Research Reactor (OSURR) is a pool‑type reactor with multiple beam ports and dry tubes as irradiation facilities, that is utilized for a variety of instructional, research, and service activities. It is licensed to operate at thermal powers up to a maximum of 500 kilowatts, and at this maximum steady‑state power, the maximum thermal neutron flux in the central irradiation facility is approximately 1.7E13 n/cm2/s.
