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.
