摘　　要：本文以重水研究堆堆本体外壳为研究对象,根据堆本体外壳的结构特点和放射性水平,从操作周期、废物量、人员受照剂量等方面对比了堆内就地切块和堆内环形拆除方案的可操作性,通过对比选择堆内就地环向切割;确定了堆本体外壳切割总体方案,在总体方案确定的前提下,根据外壳的结构特点、放射性水平等条件设计了外壳冷切割工具以及相应的工作形式,外壳切割采用机器人和机械手远程遥控切割;在调研和初步计算的基础上,选择相应的起吊工具和尺寸;根据切割线划分原则,确定了外壳切割线。This article chooses the outer vessel of HWWR reactor as subject investigated.According to the character and radioactivity level of the outer vessel,through operate time,waste volume and personnel exposure dose to compare the advantage and disadvantage of cutting ring and cutting pile in the reactor.As a result,the outer vessel of HWRR reactor is dismantled by cutting ring.This article preliminary design the dismantle plan of outer vessel.The outer vessel is dismantled by robot and manipulator remote control,On the basis of calculating,we chooses cutter and cutter point of the outer vessel of reactor.
