乏燃料后处理技术发展态势分析

以国际核信息系统(INIS)作为数据源,利用文献计量方法对1955-2012年间发表的后处理技术文献进行了统计分析。通过对国家、机构及时间的分布进行分析,发现世界后处理技术主要分布于美、日、法、德、英、印、俄7个国家,其中日本原子能研究开发机构、法国原子能委员会、德国卡尔斯鲁厄研究中心、美国橡树岭国家实验室、印度巴巴原子研究中心具有很强的研究实力。依据齐普夫定律.获得89个后处理技术文献的高频关键词。这些高频词揭示了后处理技术研究热点,即对PUREX流程进一步改进的水法流程和以高温化学流程、电解精炼、电冶金为主的干法流程。

International Development Trend Analysis of Spent Nuclear Fuel Reprocessing Technologies

Based on the International Nuclear Information System (INIS) database, quantitative analysis of the publications on reprocessing technologies is provided during the years of 1955-2012. Distribution characteristics of time, countries and institutions are analyzed. Results show that among the countries contributing to reprocessing research, USA is the forerunner followed by Japan, France, UK, Germany, Russia and India. Among the most productive organizations in this field, the top 5 are Japan Atomic Energy Agency，French Atomic Energy Commission, Karlsruhe Research Center in Germany, USDOE Oak Ridge National Laboratory and India Bhabha Atomic Research Centre. Based on Zipf's law, 89 high-frequency keywords in these literatures are obtained. These keywords reveal that the reprocessing researches focus on the evolutionary technologies based on aqueous separation (PUREX) and the “dry” technologies involved pyrochemical process, electrorefining process, and electrometallurgy process.
