Other Systems
Many systems employed within a plutonium facility are not directly related to
personnel safety and radiation protection. However, because of the special impact
that these systems may have on a plutonium facility, individuals responsible for
personnel protection should be aware of them. Some examples are as follows:
-- Process instrumentation and control indicators to monitor and maintain control
over the process and to detect and indicate abnormal and accident conditions;
-- surveillance systems to ensure the integrity of all process piping, tanks, and
other containment equipment, including those used for liquid effluent; and
-- vacuum, airlift, or gravity systems to transfer toxic or corrosive liquids or
slurries.
Special controls should be provided for flammable, toxic, and explosive gases,
chemicals, and materials that are used in plutonium-handling areas. Gas and
chemical storage facilities, including distribution piping systems, should conform
to good design practice and applicable codes and standards. Consideration should
be given to compatible groupings that, under accident or leakage conditions, would
minimize any adverse combining of materials. Means for remote shutoff of piping
should be provided. In addition, the following rules should be observed:
-- Nonflammable hydraulic and lubricating fluids should be used in the
plutonium-handling area;
-- protective barriers should be provided around high-pressure or other potentially
dangerous systems;
-- incompatible chemicals, materials, and processes should be isolated from one
another; and
-- pressurized gas lines used in the plutonium-handling areas must be properly
vented.
Facilities for equipment maintenance should be provided.
