美国和俄罗斯之间的钚管理和处置协议为处置34公吨多余的武器级钚做出了安排。根据这项协议，俄罗斯计划通过将钚加工成快中子增殖反应堆的燃料来处理其过剩库存。为了满足处置要求，这种燃料将在快堆作为燃烧器运行时燃烧，即，没有天然铀覆盖层，可以用来在核心周围增殖钚。本文讨论了反中微子监测的潜在应用，以验证存在的繁殖毯。研究发现，一个36公斤的反中微子探测器，利用相干弹性中微子核散射和硅制成的，可以确定在液体钠冷却快堆在95%的置信水平在90天内的增殖毯的存在。
ABSTRACT The Plutonium Management and Disposition Agreement between the United States and Russia makes arrangements for the disposal of 34 metric tons of excess weapon-grade plutonium. Under this agreement Russia plans to dispose of its excess stocks by processing the plutonium into fuel for fast breeder reactors. To meet the disposition requirements this fuel would be burned while the fast reactors are run as burners, i.e., without a natural uranium blanket that can be used to breed plutonium surrounding the core. This article discusses the potential application of antineutrino monitoring to the verification of the presence of a breeding blanket. It is found that a 36 kg antineutrino detector, exploiting coherent elastic neutrino-nucleus scattering and made of silicon could determine the presence of a breeding blanket at a liquid sodium cooled fast reactor at the 95 percent confidence level within 90 days.
