氘氚核聚变反应装置负压通风系统工艺设计
Process design of negative pressure ventilation system for deuterium-tritium fusion devices
摘要：
氘氚核聚变反应装置中部分区域在工艺设备运行期间会有一定程度的放射性物质产生,为保证释放到空间内的气载放射性物质不向外界扩散及能实现从污染程度低的区域流向污染程度高的区域,需要涉放区域维持规定的负压梯度。本文以紧凑型聚变能装置为例,介绍了氚包容负压通风系统及其工艺设计要求和设计方案。

Abstract：
In the specific areas of a deuterium-tritium fusion device, there are some radioactive substances produced during the operation of the process equipment. To prevent the airborne radioactive substances released into space from spreading to the outside and to facilitate flow from low-contaminated to high-contaminated areas, it is essential to keep a specified negative pressure gradient in the radioactive area. Taking a compact fusion energy device as an example, this paper presents the tritium containment negative pressure ventilation system, its process design requirements and design scheme.
