摘要: 嫦娥四号任务中,我国首次采用国产同位素热源为航天工程提供能源。为确保任务安全实施,需要对其从研制到发射全过程进行安全监管,热源相关的放射性物质运输活动作为一种移动的放射性风险源尤其需要重视。本文从分析热源的放射性特性入手,通过调研国内外已有的核安全监管要求,特别是国际原子能机构、俄罗斯、美国的监管资料,对热源运输各监管环节进行拆解,筛选分析出适合我国同位素热源运输监管的具体要求,并运用于热源核安全监管的实践中。

Abstract: In the chang’e-4 project, China used domestic radioisotope heat sources to provide energy for aerospace projects for the first time. In order to ensure the safe implementation of the mission, it is necessary to carry out nuclear safety regulation on the whole process from development to launch, while the domestic mature safety regulation experience on such domestic radioisotope heat source products is insufficient. Starting with the analysis of the radioactive characteristics of heat source, this paper investigates the existing nuclear safety regulatory requirements at home and abroad, especially the regulatory data of the International Atomic Energy Agency, Russian Federation and the United States. This paper also disassembles the regulatory links of heat source transportation, selects and analyzes the specific requirements suitable for the safety regulation of isotopic heat source transportation in China.

Key words: isotope heat source, transportation, nuclear safety regulation
