The broader impact/commercial potential of this I-Corps project is the improved safety and reduced cost of managing nuclear waste. Current lightweight radiation shielding materials lack the required temperature stability. New radiation shielding materials with better properties are needed to protect the health of biological, electrical, and structural systems in radioactive environments. Radiation shielding improvements in the nuclear industry could result in upwards of one billion dollars in savings annually and result in lower electricity costs. Commercialization of these advanced materials can also minimize the effects of disasters like Fukushima and reduce the costs of clean-up efforts. Lightweight radiation shielding materials are also needed in airplanes and satellites to protect workers and electronic systems from cosmic radiation and for medical personnel working with radiation related treatments. This I-Corps project is based on an innovative lightweight radiation shielding material that withstands operating temperatures nearly double those of commercially available products. It has been demonstrated that the addition of carbon-based particles can more quickly move heat away from radioactive waste; this enables safer disposal options for the nuclear waste. Additional technical merit lies in the fabrication process that has been developed to reduce the weight and size of the material. It also enables the technology to be cost competitive with existing products while providing better shielding properties. The I-Corps investigation will determine the commercial potential for this material.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.

该I-Corps项目的更广泛的影响/商业潜力是改善安全性和管理核废料的成本。 当前的轻质辐射屏蔽材料缺乏所需的温度稳定性。 需要具有更好性能的新辐射屏蔽材料来保护放射性环境中生物，电气和结构系统的健康。 核工业的辐射屏蔽改善可能会导致每年节省10亿美元，并导致较低的电力成本。 这些先进材料的商业化还可以最大程度地减少福岛等灾害的影响，并降低清理工作的成本。 飞机和卫星中还需要轻巧的辐射屏蔽材料，以保护工人和电子系统免受宇宙辐射以及与辐射相关治疗的医务人员。 该I-Corps项目基于一种创新的轻质辐射屏蔽材料，该材料承受运营温度几乎是商业产品的两倍。 已经证明，添加碳基颗粒可以更快地将热量从放射性废物中移开。这可以使核废料的更安全处置选择。 额外的技术优点在于制造过程，该过程已开发出来减少材料的重量和大小。 它还使该技术能够与现有产品具有成本竞争力，同时提供更好的屏蔽性能。 I-Corps的调查将确定该材料的商业潜力。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛的影响评估标准来评估值得支持的。
