7013-SEC-001 Secondary Enclosure Clean-up System (SEC) 二次封闭清洁系统(SEC)

Tritium has the ability to permeate elastomers and metal walls, particularly when the walls are heated. It is for this reason that tritium systems are usually put inside secondary enclosures or glove boxes. Since it is likely that the glove box atmosphere will eventually become contaminated with tritium, an atmosphere clean-up system is often required. This clean up system is sometimes referred to as a Secondary Enclosure Clean-up System or SEC System. The clean-up system can also regulate temperature, humidity, and remove other impurities.氚具有渗透弹性体和金属壁的能力,尤其是当壁被加热时。正是由于这个原因,氚系统通常被放置在二次外壳或手套箱内。由于手套箱的大气可能最终会被氚污染,所以通常需要一个空气净化系统。这种清理系统有时被称为二级封闭清理系统或SEC系统。清洁系统还可以调节温度、湿度和清除其他杂质.
