quality, secondary containment jackets are most often used to enclose primary

containment system plumbing when the primary system plumbing is used to

connect systems between one glovebox and another inside a room, between

one system and another inside a building, and between one system and another

when the systems reside in different buildings. High-quality, secondary jackets

are also used quite extensively to enclose primary-containment-system, high-

pressure vessels, where the failure of the primary system vessel might be

expected to release large quantities of tritium. (See, for example, Figure 8.)

High-quality, secondary jackets are also used to enclose individual primary

containment system components that are temperature cycled on a routine basis.

In this case, however, the purpose of the high-quality secondary containment

jacket is to capture any tritium that has permeated through the walls of the

primary system component as a direct result of the temperature cycling.
