Guide of Good Practices for Occupational Radiological Protection in Plutonium Facilities

-- 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.
