The results of a study of the effect of the homogeneous addition of ²³⁷Np, ²⁴¹Am, ²⁴³Am into the fuel on the neutronics characteristics of a lead-cooled fast reactor are reported. The reasons for the change in the delayed- neutron fraction and the effective delayed-neutron fraction, breeding ratio, density effect of reactivity, and residual energy release of the fuel unloaded from the core are analyzed. The transmutation efficiency was determined for the starting actinide fraction 3–5% h.a. mass in the fuel.

铅冷快堆中 237Np、241Am、243Am 的均相嬗变

报告了在燃料中均匀添加²³⁷ Np、²⁴¹ Am、²⁴³ Am 对铅冷快堆的中子学特性影响的研究结果。分析了延迟中子分数和有效延迟中子分数变化的原因、增殖比、反应性的密度效应以及从堆芯卸载的燃料的残余能量释放。嬗变效率由燃料中 3-5% 公顷质量的起始锕系元素部分确定。
