摘要
为减少氚污染金属手套箱退役解体过程中氚的二次释放,降低工作人员的辐射危害,减少退役中产生的氚污染废物量,本文针对退役氚污染金属手套箱的解体,设计了氚污染金属手套箱退役解体技术方案,即解体前对氚污染金属手套箱进行初步去污,解体中采用合适的切割技术和相应的防护措施。利用氚污染金属手套箱对该解体方案进行了验证,结果表明,设计的解体方案满足氚污染金属手套箱退役需要。
The scheme of decommissioning tritium contaminated metal glovebox was designed,which can reduce tritium gas release during the glovebox dismantling,the volume of tritium waste and the radiation damage.The scheme includes a preliminary tritium decontamination before the glovebox dismantling,a suitable cutting technology for the glovebox and a multiplex protection.A test for tritium contaminated metal glovebox dismantling was performed successfully with this scheme.The results show that the scheme is able to meet the demands for decommission of tritium contaminated metal glovebox.
