C.4.4.2

Personnel-Decontamination Room

A personnel-decontamination room (or station) should be provided for

each plutonium facility. It should be located near or in the change rooms.

A decontamination room with the capability to decontaminate male and

female personnel simultaneously should be considered. The use of

installed partitions or curtains should be considered for this purpose. An

adequately equipped decontamination room should have communications

equipment, a workbench with a cabinet for decontamination supplies, an

examination chair, a sink, and showers. Both the sink and showers

should be connected to a holding tank for sampling or routed to the

process waste. The room should contain equipment for performing nasal

irrigations and initial surveys of nasal swipes.

C.4.4.3

Health Physics Laboratory Office

Health physics personnel in a plutonium facility should be assigned

laboratory office space at or near the exit from the process area into the

controlled area. As a rule of thumb for determining space needs, one

radiation protection technologist should be available for every 10

radiation workers. Space should be included for the readout of radiation-

protection instrumentation, preparation of radiation protection records,

counting equipment, and storage of portable instruments.

C.4.4.4

Mechanical Equipment

Where possible, mechanical equipment (e.g., motors, pumps, and valves

that may be a source of radioactive contamination) should be located in

the process area. Enclosures that will contain the contamination should

be placed around the equipment. Such enclosures should be easy to

decontaminate.

C.5 SERVICE AND UTILITY SYSTEMS

Utility services should be designed to provide reliability that is consistent with 1) the

operational requirements for the control and confinement of radioactive materials and 2)

the potential hazards under all probable conditions. The services and utilities that are

important to the continuity of essential plant functions should be designed to the same

integrity level as the function they serve. Some service or utility systems are connected to

other systems or structures that are essential to prevent the release of radioactive materials.

Such service or utility systems must be designed so that if they fail, connecting systems

will remain functional.

C.5.1

Ventilation Systems

Ventilation systems include the supply and exhaust systems and the associated

ductwork, fans, air cleaning, tempering, or humidity control devices, and associated

monitoring instrumentation and controls required to confine radioactive materials

within the ventilation system. The design of ventilation system components does

not include process vessels, primary confinement or containment housing, or the

building structure.
