Abstract

Simulations were conducted in MCNP6.1 modeling the neutron fluence through a cryogenically cooled ¹³²Xe target to optimize activation rates from a neutron generator source. These simulations evaluated a combination of moderator and reflectors materials with DT and DD neutrons to model the changes in the activation rates of ¹³³Xe, ^133mXe, and ^131mXe as a function of thickness. ¹³³Xe and ^133mXe activation rates were simulated to increase by 31%, 16% respectively with a light water reflector 128 mm in thickness. Production of ^131mXe had a simulated increase of 2.7% with a graphite reflector 85 mm in thickness.
