G. Definitions

The source or basis for the following definitions is indicated in parentheses after the defined term.

1. Chamber

The separator vacuum vessel and associated hardware and product collection system.

2. Nuclear materials

"All materials so designated by the Secretary of Energy. Presently, these materials are: depleted uranium, enriched uranium, americium-241, americium-243, curium, berkelium, californium, plutonium 238-242, lithium-6, uranium 233, normal uranium, neptunium-237, deuterium, tritium, and thorium." (DOE order 5633.3)

3. Product

Plutonium enriched in 239Pu.

4. Production facility

"(1) any equipment or device determined by the rule of the (Secretary of Energy) to be capable of the production of special nuclear material in such quantity as to be of significance to the common defense and security, or in such manner as to affect the health and safety of the public; or (2) any important component part especially designed for such equipment or device as determined by the (Secretary of Energy)." (AEA of 1954, as amended.)

5. Refractory material

Graphite, metal, or ceramic bulk materials; coatings; or treated surfaces that are resistant to dissolution in liquid actinides.

6. Restricted Data

"all data concerning (1) design, manufacture, or utilization of atomic weapons; (2) the production of special nuclear material; or (3) the use of special nuclear material in the production of energy, but shall not include data declassified or removed from the Restricted Data category pursuant to Section 142" (AEA of 1954, as amended.)

7. Separator line

A glove-box assembly that contains a series of separator units housed in vacuum chambers, along with the necessary hardware to provide an optical pathway for the process laser beam through the separator units.

8. Separator unit

The assembled vapor source, feeder, collimator, extractor, product collector, and support frame.

9. Special Isotope Separation

Plutonium isotope separation.

10. Special nuclear material

"...(1) plutonium, uranium enriched in the isotope 233 or in the isotope 235, and any other material which the (Secretary of Energy) ... determines to be special nuclear material; or (2) any material artificially enriched by any of the foregoing..." (AEA of 1954, as amended.

11. Weapons-grade plutonium

"Plutonium containing 8 percent or less 240Pu. Nominally 6 percent 240Pu, 0.5 percent 241Pu, some 238Pu, remainder 239Pu." (CG-W-5)
