The broader impact/commercial potential of this Partnerships for Innovation - Technology Translation (PFI-TT) project is to enable the widespread adoption of advanced nuclear reactors by providing a non-invasive and environmentally responsible method to account for the plutonium produced during the operation of the reactor. Nuclear reactors serve as a source of electric power but also produce plutonium, which can be extracted from the used nuclear fuel and used for other purposes. The proposed project will develop a next-generation plutonium detector. The proposed project will determine the detector performance requirements for real-world plutonium detection. Neutrino detection can track plutonium production by measuring the effect it has on the spectrum of neutrinos emitted by the reactor. This project will develop: 1) new readout electronics; and 2) a new cosmic-ray neutron shield to reduce the rate of observed background events by an order of magnitude. This project includes a field test for system validation and verification.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这一创新-技术转化伙伴关系(PFI-TT)项目的更广泛影响/商业潜力是，通过提供一种非侵入性和对环境负责的方法对反应堆运行期间产生的钚进行核算，使先进核反应堆得以广泛采用。核反应堆是电能的来源，但也会产生钚，钚可以从用过的核燃料中提取出来，用于其他目的。拟议的项目将开发下一代钚探测器。拟议的项目将确定现实世界钚探测的探测器性能要求。中微子探测可以通过测量钚对反应堆发射的中微子光谱的影响来跟踪钚的产生。该项目将开发：1)新的读出电子设备；2)新的宇宙射线中子屏，将观测到的背景事件的速率降低一个数量级。该项目包括系统验证和验证的现场测试。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
