IMF燃耗特性与次锕系核素产量分析
Study on Burnup Characteristics and MA Production of IMF
摘要
Abstract
The adoption of inert matrix fuel (IMF) can effectively reduce the amount of minor actinide (MA) in spent fuel of LWR from the source .In order to study the burn‐up characteristics of IMF ,the two typical IMF schemes of PuO2 + ZrO2 + MgO and PuO2 + ThO2 were selected ,and the IMF reactivity with different amounts of PuO2 was calculated .And the comparison among IMF ,UO2 and MOX was made .The results show that after 36 months operating ,with the PuO2 volume fractions of two types of IM Fs from 2% to 10% ,their kinf values at the end of cycle are all above 1 .But the burn‐up reactivity of PuO2 +ZrO2 + MgO scheme is greater than that of PuO2 + ThO2 .The amount of MA at the end of cycle in PuO2 + ThO2 scheme is obviously smaller than the former .Under the same effective heavy metal weight percentage ,the amounts of MA in MOX and UO2 fuels at the end of cycle are both greater than those of the two types of IM Fs .关键词
