3.4 Facility Any equipment, structure, system, process, or activity that fulfills a specific

purpose. Examples include accelerators, storage areas, fusion research devices, nuclear

reactors, production or processing plants, coal conversion plants, magnetohydrodynamics

experiments, windmills, radioactive waste disposal systems, and burial grounds,

environmental restoration activities, testing laboratories, research laboratories,

transportation activities, and accommodations for analytical examinations of irradiated and

unirradiated components.

(DOE 5000.3B)
