陶瓷是固化和储存高放废物（HLW）的替代品之一。开发定制陶瓷的程序已经开发出来，其中高放离子固定在相互兼容、耐火和抗浸出的晶相中。太平洋西北实验室 (PNL) 对早期陶瓷配方进行了冷工程规模评估，结果发现该产品易于结晶，并且具有足够的热稳定性和抗浸出性。当与 PNL 开发的连续造粒和涂层工艺相结合时，迄今为止的结果表明，定制陶瓷和多层废物形式是非常有前途的高放固体玻璃的先进替代品。 5张图，3张表格。
A ceramic is one of the alternatives for solidification and storage of high-level wastes (HLW). The procedure for developing a tailor-made ceramic with HLW ions fixed in mutually compatible, refractory and leach-resistant crystalline phases has been developed. Cold engineering-scale evaluation of an early ceramic formulation at Pacific Northwest Laboratories (PNL) has resulted in a product that is easily crystallized and has more than adequate thermal stability and leaching resistance. When combined with the continuous pelletizing and coatings processes developed at PNL, the results to date demonstrate that the tailor-made ceramic and the multibarrier waste forms are very promising advanced alternatives to glass as an HLW solid. 5 figures, 3 tables.
