Large-scale hot-isostatic pressing of waste forms for the treatment of Magnox sludge and other wastes

放射性废物的热处理提供了显著减少废物体积和实现生命周期成本节约的机会。在本项目中，GeoRoc有限公司旨在演示使用热等静压（HIPing）处理镁诺克斯燃料池污泥。热等静压涉及使用热和压力来制造致密材料。热等静压是一种成熟的先进材料生产方法。然而，需要进行设计创新，以使其适应放射性废物处理的常规用途。通过选择定制的添加剂，可以通过HIP生产地质稳定并锁定核废物的高废物负载陶瓷和玻璃陶瓷。环境效益不仅限于将现有和未来的废物转化为稳定的形式，而且由于这是一个密封的过程，它消除了任何放射性或化学毒性废物释放的可能性，此外，减少的体积也减少了所需的储存空间，从长远来看，将需要更少的储存库，减少二氧化碳排放，节省的资金可用于其他政府举措。

The thermal treatment of radioactive wastes offers the opportunity to significantly reduce the waste volume and realise life-cycle cost savings. In this project GeoRoc Limited aims to demonstrate the use of Hot-isostatic pressing (HIPing) to treat Magnox Fuel Pond Sludges. Hot-isostatic pressing involves the use of heat and pressure to make dense materials. HIPing is a mature advanced materials production method. However, design innovation is required to adapt it to routine use in the treatment of radioactive wastes. By selecting tailored additives, high waste loading ceramics and glass-ceramics that are geologically stable and lock-up the nuclear waste, can be produced via HIPing. The environmental benefits are not limited to transforming existing and future wastes into stable forms and because it is a sealed process it eliminates the potential for any release of radioactive or chemotoxic waste , additionally the reduced volume also less repository space is required and in the long term less repositories will be required, reducing CO2 emissions plus the savings could be utilised for other Government initiatives.
