Transmutation of MA in the high flux thermal reactor

The SCALE simulation shows that after 300-day-exposure in high flux thermal reactor the disappearance rate of Np-237, Am-241 and Am-243 are 73.7%, 98.1% and 82.8% respectively. The SCALE simulation results also show that the total transmutation rate of MA nuclides by fission which include direct and indirect fission after 300-day-exposure in the high flux thermal reactor is 6.3%. The SCALE simulation indicates at least 44.2% MA nuclides transmute to plutonium isotopes by various reactions and 63% of the Pu-238 in the MOX fuel is consumed during 300-day-exposure in this reactor.
