Fast reactors can be used to adjust the isotopic composition of plutonium from spent mixed uranium-plutonium fuel from PWR and make it recyclable. The efficacy of such an adjustment is directly related to the scope for breeding in fast reactors. This can be done in the operating BN-800 reactor by multiple recycling of plutonium in the fuel of the fast reactor as well as by using 235U or in specialized (target) fuel assemblies with reduced plutonium content. The international project with the use of BN-800 will make it possible to experimentally demonstrate this possibility on representative batches of plutonium (up to 100 kg/yr) as well as to work out the particularities of international and national laws in the field of accounting and moving of nuclear materials. A commercially significant project (with a turnover of 1 t or more of plutonium per year) to adjust the plutonium composition can be planned when a series of commercial high-power fast reactors with a heightened breeding ratio is put into operation.

钚同位素组成的快速反应堆辅助调整

快堆可用于调整压水堆废铀-钚混合燃料中钚的同位素组成,使其可回收利用。这种调整的效果与快堆增殖的范围直接相关。这可以在运行中的 BN-800 反应堆中通过快堆燃料中的钚的多次循环以及使用235U 或钚含量降低的专用(目标)燃料组件。使用 BN-800 的国际项目将有可能在代表性批次的钚(高达 100 公斤/年)上通过实验证明这种可能性,以及制定会计领域国际和国家法律的特殊性和核材料的移动。当一系列具有更高增殖比的商业大功率快堆投入运行时,可以规划一个具有商业意义的项目(每年 1 吨或更多钚的周转量)来调整钚成分。
