Abstract

The applicability of bentonite clay-based ceramics for immobilization of waste from pyrochemical reprocessing of spent nuclear fuel–spent electrolyte, which consists of alkali metal chlorides, was studied. Main matrix characteristics such as the phase composition, mechanical durability, leaching rate and microstructure were studied. The results obtained were compared to the requirements to the cement compound, formulated in NP-019-15 document. The matrix was considered to be suitable for the radioactive waste disposal.

评估基于膨润土的陶瓷在固定乏核燃料热化学处理过程中产生的放射性废物方面的适用性

摘要研究了膨润土基陶瓷在固定乏核燃料热化学后处理产生的废物（包括碱金属氯化物）方面的适用性。研究了主要基体特征，如相组成、机械耐久性、浸出率和微观结构。研究结果与 NP-019-15 号文件中对水泥化合物的要求进行了比较。该基质被认为适用于放射性废物处置。
