摘要

WWR-M是一种轻水冷却和慢化非均质研究堆，热输出功率为10兆瓦。最后的退役计划正在进行中。一般的退役策略包括拆除和单独拆除整体(整体)的大型部件，而不进行初步分割。一次和二次冷却回路的拆除被认为是关键任务之一;已开发出一种单独的拆卸设计。本文提出了技术解决方案和安全的基本原则。剂量评估结果表明，这项工作可以在低于20人毫西弗的集体剂量下进行。

Assessment of the dose load during the dismantling of the WWR-M reactor

The WWR-M is a light-water-cooled and moderated heterogeneous research reactor with a thermal output of 10 MW. The final decommissioning planning is in progress now. The general decommissioning strategy consists of the dismantling and separate removal of the bulky elements as a whole (in one piece) without preliminary segmentation. The dismantling of the primary and secondary cooling loops is considered as one of the key tasks; a separate dismantling design has been developed. The baseline principles for the technical solution and safety are presented in the given paper. Results of the dose assessment showed that the work can be performed at a collective dose of less than 20 man-mSv.
