摘要
一、前言随着核动力的发展,由核电站产生的废物量也随之增加,这些废物的处理和处置是核工业面临的主要问题。用离子交换树脂净化反应堆主回路冷却水,经过一段时间以后,其具有很强的放射性,需要排出进行处理。树脂因颗粒小,易分散、着火和引起污染。
Dewatering and drying the radioactive spent resins generated from nuclear power plants are studied in laboratory. A simple way is filtering and heat- drying the resins in vacuum. The important parameters of the process are determined. After filtering under vacuum the percentage of water in cation is about 53%～57%. By means of heat-drying in vacuum the water content of cation resin ,anion resin and mixed bed resin can be further decreased to 46%～48% ,30% and40% ,respectively. The resins treated have good mobility. The operation time is about six houts.
