Hazards Separation

1.1.3

Hazards Separation . Hazards separation design considerations include

establishing the attendant degree of risk, and taking into account the potential for

Nuclear Facility Building Layout . In addition to the usual industrial safety

required in a nuclear facility, the following features should be considered:

Rectangular and windowless storage buildings should be used, where

practical.

Provide for efficient cleaning, maintenance, and ease of inspection in the

facility layout.

Consider occupancy time, spacing, remote handling equipment, and

shielding.

Air locks or enclosed vestibules should be considered for access through

1.1.4

Hazardous Areas .

Alarms and Interlocks . Provide sufficient alarms and interlocks in hazardous

areas, such as radioactive spaces or spaces with inert atmospheres Prevent

inadvertent entry into hazardous areas by providing cautionary systems or

interlocks. Additional considerations include--

Consider automatic monitoring and alarm devices to detect the presence

of significant levels or increases of radioactivity or other hazardous

materials.

Consider the need for visual alarm devices within the special facility in

addition to audible alarm devices.

Provide criticality alarms or evacuation alarms to preclude or minimize

exposures outside the facility.
