钍铀核燃料循环研究

本文报道了中国科学院上海原子核研究所在开展钍铀燃料循环研究方面的进展和取得的成果。这些研究主要为克级量纯~(253)U的提取、钍基燃料后处理技术研究、新的铀钍萃取体系的研究、钍铀镤分离和分析方法研究、中子辐照ThO_2时产生有关核素的累积与中子积分通量和中子能谱的关系、钍的零功率试验等。本文还对钛的利用进行了评估和展望。

Study on the thorium-uranium fuel cycle

In the past over years the research and development on the thorium-uranium fuel cycle have been carried out at Shanghai Institute of Nuclear Research, particularity on the preparation of pure 288U, reprocessing of thorium-based spent fuel, new extractive systems for thorium and uranium, new methods of separation and analysis of thorium, uranium and protactinium, basic research on utilization of thorium-based nuclear fuel,and critical experiments of thorium. In this paper the perspective of thorium utilizationin nuclear reactors has also been evaluated.
