containment systems, such as gloveboxes, are used to help minimize any tritium

releases into the facility and/or out to the environment. Because gloveboxes

can be constructed to accommodate all kinds of equipment, most primary

containment systems are housed inside gloveboxes in modern tritium facilities.

(See Figure 9.) When properly designed, gloveboxes allow access to the

primary system equipment for ease of operation and maintenance. Gloveboxes

are referred to as intermediate-quality systems because the design

requirements do not have to meet codes and standards as stringent as the

ASME Boiler and Pressure Vessel Code.
