【 摘 要 】

The estimation of weekly99Mo production by AHR 200 kW fueled with Low Enriched Uranium Uranyl Nitrate solution has been simulated by using MCNPX computer code. We have employed the AHR design of Babcock & Wilcox Medical Isotope Production System with9Be Reflector and Stainless steel vessel. We found that when the concentration of uranium in the fresh fuel was 108 gr U/L of UO2(NO3)2fuel solution, the multiplication factor was 1.0517. The99Mo concentration reached saturated at tenth day operation. The AHR can produce approximately 1.96×1036-day-Ci weekly.
