Uncertainty analysis on fission Mo production in HANARO

Uncertainty analysis on fission-produced molybdenum production with low enriched uranium (LEU) and high enriched uranium (HEU) was performed using Crude Monte Carlo Method. The most important parameter affecting uncertainty of 99Mo yield and annul production amount was fuel thickness for LEU target. Therefore, it was important to minimize the fuel film fabrication tolerance for LEU target. Uncertainty of minimum required decontamination factor(MRDF) to satisfy U. S. P. (Unites States Pharmacopoeia) standard was very small for both target. Decontamination of Pu which is α-emitter was shown to be impossible using current. Cintichem porcess in LEU. However, it can be overcome by addition of one more purification step, because the uncertainty of MRDF was small within 3% for 10 confidence level
