Abstract
The Aerojet General Nucleonics Model 201-M (AGN-201M) research reactor at the University of New Mexico (UNM) has been in operation for over 50 years. The AGN reactor core is a mixture of lowenriched UO2 (19.5 wt % 235U) powder and polyethylene reflected with 20 cm of reactor-grade graphite. It has a critical mass of 665 g 235U and a licensed maximum power of 5 W thermal. The AGN reactor is controlled using four fueled control rods which are driven into the core from the bottom of the reactor. The AGN core and reflector configuration allows the reactor to operate with a minimal quantity of fissile material but with enough excess reactivity to allow for significant research flexibility.
