Facilities

Research Reactor

The OSU-NRL features The Ohio State University Research Reactor (OSURR), 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 1.4x1013 n/cm2/s.

Gamma Irradiators

The OSU-NRL houses a 60Co irradiator with a dose rate and profile seen here. 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 seen in the page linked above.

The NRL also houses a bench-top cesium irradiator. The space for sample irradiations is ~ 7.75" in length by 3.75" in diameter, and the dose rate in the sample irradiation can be seen here.

Gamma-Ray Spectroscopy System

The NRL gamma spectroscopy lab has three high-resolution gamma spectroscopy detectors. All of them are high purity germanium detectors (HPGe) housed in copper-lined lead caves to reduce background.

Graphite-Moderated Subcritical Reactor

The NRL houses a graphite-moderated subcritical reactor utilizing natural-enrichment uranium. The subcritical reactor is used for lab classes and low-flux neutron irradiations.
