MOCK OPERATION EXAMPLES

This section examines major operations described in appendix B. For example purposes,

aspects of operations are discussed only where potential new ARF applications or unique

circumstances exist. In specific example topic tables, the entry "none" under a subject

heading indicates no illustrative examples are presented for that subject, even though it may

exist or be possible (i.e., criticality) in the specific example operation under consideration.

The entry "N/A" means the subject is not applicable to the specific example operation under

consideration. Appendix B provides detailed descriptions of the mock operations examined

at a level sufficient to understand the examples, including basic flow diagrams.

7.3.1.1

Hazard Summary

This activity handles only solid materials in the form of plutonium oxide, plutonium residues,

or plutonium metal fines in oxide feed. The only major energy sources in the glovebox are a

muffle furnace for burning impure oxide feed and a small impactor that breaks up residues.

A 0.21 MPag (30 psig) air line supplies a glovebox branch line to provide forced air to the

furnace. A 0.1 MPag (15 psig) nitrogen supply can provide inerted ventilation for the

glovebox, but it is not normally used. There are no large accumulations of combustible

material in the glovebox or room, nor is there any reason for the operation to accumulate

large amounts of combustible material. Likewise, there are no significant explosive energy

sources in the room.
