7013-SEC-001 Secondary Enclosure Clean-up System (SEC) 二次封閉清潔系統(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.氚具有滲透彈性體和金屬壁的能力,尤其是當壁被加熱時。正是由于這個原因,氚系統通常被放置在二次外殼或手套箱內。由于手套箱的大氣可能最終會被氚污染,所以通常需要一個空氣凈化系統。這種清理系統有時被稱為二級封閉清理系統或SEC系統。清潔系統還可以調節溫度、濕度和清除其他雜質.
