In actual practice, the tanks are not filled to their maximum capacity due to requirements to

maintain a minimum level of freeboard.

2.2.2.4 S am p lin g

The sampling glovebox line is located directly north of tank farm enclosure #1 between the

maintenance sides of the dissolving line and the wet processing line. It consists of three

distinct sampling systems of the type previously described in section 2.1.5.7 and a slab

vessel. The principal function of this glovebox is to draw liquid samples in 20-ml sample

vials. Liquid is recirculated from the tank selected through a pump in the glovebox and back

to the source tank. When sufficient recirculation or mixing occurs, the sample vial is

inserted into the system and a sample drawn. A secondary purpose of this glovebox is to

recirculate tanks if necessary for mixing.

The three sampling systems provided in the glovebox are completely independent and do not

share pumps or piping. The first system samples the dissolver solution tanks (#1 through #6)

before the ion exchange process has occurred. If a spill has occurred in a glovebox sump,

necessitating the need to collect the solution in tank #15, the first sample system is used to

sample this tank. The spare tank, #16, is normally jumpered into this system as well if it is

being used. The second system samples the ion exchange eluate and precipitator feed tanks

(#7, #8, #13, and #14). The third system samples the waste holding tanks (#9 - #12, #17 -

#21).
