氢化钚与CO反应体系有七个独立组分、四种元素和三个独立反应方程式 ,分别计算了CO(g)、CO2(g)和H2 (g)在同时反应和单独反应中的平衡组成。计算表明 :同时反应有耦合作用 ,低温有利于CO(g)的转化和Pu2 O3(s)的生成。与单独反应相比 ,体系中有较多的Pu2 O3(s)生成 ,其平衡组成也有较大差异。计算结果对钚的表面防腐有一定的参考价值。 Hydrogenated plutonium and CO reaction system has seven independent components, four elements and three independent reaction equations were calculated CO (g), CO2 (g) and H2 (g) in the simultaneous reaction and the equilibrium composition of the separate reactions . Calculations show that there is a coupling reaction at the same time. Low temperature is favorable for the conversion of CO (g) and the formation of Pu2 O3 (s). Compared with the single reaction, there are more Pu2 O3 (s) in the system, and the equilibrium composition is quite different. The calculation results have a certain reference value for the surface preservation of plutonium.
