Safer, low-cost nuclear material storage through cold spray-formed boron carbide coated components (SafeStore)Transport and/or storage of spent nuclear fuel can require neutron shielding materials. Two such materials currently used are composite plate materials consisting of aluminium (or aluminium alloys) containing varying proportions of boron carbide particulates, which have a high neutron absorbing capability. Whilst these metal matrix composite (MMC) materials are suitable for specific niche applications, the current manufacturing route is unable to produce them in anything other than flat solid plates. This limits the design options for containers/canisters.In the SafeStore project, cold spray coating technology was used to develop a material that is similar to the MMC but can be applied to sheet metal fabrications in any desired thickness up to tens of millimetres. Cold spray technology facilitates the co-deposition of thermally sensitive and/or easily oxidised materials such as Al and B4C without thermal degradation. The coatings were developed and applied to steel samples and plates and the deposition parameters were then further improved to obtain higher levels of B4C in the coatings.The use of a coating results in better design flexibility and hence better and more cost-effective dry cask storage options. The project was led by Graham Engineering, a UK-based company with a strong track record in the supply of nuclear waste fuel containers. TWI conducted the coatings development work whilst Graham Engineering helped define the market needs and facilitated the characterisation and evaluation of the radiological performance of the coatings.Project Participants and TSB GrantGraham Engineering Ltd – Grant £27,000TWI Ltd(Industrial) – Grant £67,500Total Grant = £94,500

通过冷喷涂成型的碳化硼涂层部件实现更安全、低成本的核材料储存（SafeStore）乏核燃料的运输和/或储存可能需要中子屏蔽材料。目前使用的两种此类材料是由含有不同比例的碳化硼颗粒的铝（或铝合金）组成的复合板材料，具有高中子吸收能力。虽然这些金属基复合材料（MMC）适合于特定的利基应用，但目前的制造路线无法将它们生产成除了平面固体板之外的任何东西。在SafeStore项目中，冷喷涂技术被用于开发一种类似于MMC的材料，但可以应用于任何所需厚度的金属板制造，最大厚度可达数十毫米。冷喷涂技术有助于热敏和/或易氧化材料（如Al和B4 C）的共沉积，而不会发生热降解。开发了这些涂层并将其应用于钢样品和板材，然后进一步改进沉积参数，以在涂层中获得更高水平的B4 C。涂层的使用带来了更好的设计灵活性，从而提供了更好、更经济的干桶储存选择。该项目由格雷厄姆工程公司领导，该公司是一家总部位于英国的公司，在核废料燃料容器供应方面有着良好的记录。TWI进行了涂层开发工作，而Graham Engineering帮助确定了市场需求，并促进了涂层辐射性能的表征和评估。项目参与者和TSB GrantGraham Engineering Ltd - Grant £27，000 TWI Ltd（工业）- Grant £67，500总资助= £ 94，500
