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.

这种创新合作伙伴关系的更广泛的影响/商业潜力 - 技术翻译（PFI-TT）项目是通过提供一种无创和对环境负责的方法来说明反应堆运行过程中产生的plut骨，从而使高级核反应堆的广泛采用。 核反应堆是电力的来源，但还产生p，可以从使用的核燃料中提取并用于其他目的。 拟议的项目将开发下一代p prut探测器。拟议的项目将确定现实世界中plut子检测的探测器性能要求。中微子检测可以通过测量其对反应器发出的中微子的影响来追踪p的产生。该项目将开发：1）新的读取电子设备； 2）一种新的宇宙射线中子屏蔽，以减少观察到的背景事件的速率。 该项目包括用于系统验证和验证的现场测试。该奖项反映了NSF的法定任务，并被认为是使用基金会的知识分子优点和更广泛影响的评论标准的评估值得支持的。
