C.2 DESIGN OBJECTIVES
The design of a plutonium facility should achieve the following objectives:
-- Protect the public and facility personnel from hazards associated with the use of
radioactive and other hazardous materials as a result of normal operations, anticipated
operational occurrences, and design-basis accident conditions, including the effects of
natural phenomena pertinent to the site, and maintain these effects ALARA;
-- ensure compliance with DOE policies regarding nuclear safety, criticality safety,
security protection for special nuclear material;
-- protect government property and essential operations from the effects of potential
-- minimize exposures of personnel and the general public to hazardous material by
emphasizing ALARA concerns during all design, construction, and operational phases.
10 CFR 835.1002 Facility design and modifications provides requirements for the design
-- Optimization methods shall be used to assure that occupational exposure is maintained
ALARA in developing and justifying facility design and physical controls.
-- The design objective for controlling personnel exposure from external sources of
radiation in areas of continuous occupational occupancy (2000 hours per year) shall be
to maintain exposure levels below an average of 0.5 mrem (5 microsieverts) per hour
and as far below this average as is reasonably achievable. The design objectives for
exposure rates for potential exposure to a radiological worker where occupancy differs
from the above shall be ALARA and shall not exceed 20 percent of the applicable
standards in § 835.202.
-- Regarding the control of airborne radioactive material, the design objective shall be,
under normal conditions, to avoid releases to the workplace atmosphere and in any
situation, to control the inhalation of such material by workers to levels that are
ALARA; confinement and ventilation shall normally be used.
-- The design or modification of a facility and the selection of materials shall include
features that facilitate operations, maintenance, decontamination, and
