The AGN-201 is South Korea's first educational research reactor. In March 1976, Colorado State University donated the AGN-201 reactor to Kyung Hee University, and in October 1980 construction for the facility to house the reactor began in Suwon, Kyonggi Province. [1] The AGN-201 reached criticality in November 1982, and became operational the following month. [2] The reactor was initially named the Kyung Hee [Kyonghui] Research Reactor (KRR), but it was later changed to its original name—the Aerojet General Nucleonics Model No. 201 (AGN-201).

The AGN-201 is housed at Kyung Hee University's Department of Nuclear Engineering, and is operated by a staff of two members of the department. Students of the Department of Nuclear Engineering use the reactor about eight hours per week for experimental testing and applications, and graduate students use the reactor approximately four hours per week for research purposes. [3] The AGN-201 uses polyethelene as a moderator and graphite as a reflector. In addition, the reactor is equipped with one thermal column, eight access ports, one glory hole, and one neutron source. The reactor uses 20 percent enriched uranium for fuel, and the fuel rods are provided by Aerojet General Nuclear of the United States. [4]
