CONCEPTUAL DESIGN. The activities required to evaluate project design alternatives and

85.

to develop sufficient detail to baseline the scope, cost and schedule for project authorization.

[DOE G 433.1-1]

86.

CONCLUSIONS. Significant deductions derived from analytical results. Conclusions are

derived from and must be supported by the facts, plus the results of testing and analyses

conducted. Conclusions are statements that answer two questions the accident investigation

addresses: what happened and why did it happen? Conclusions include concise

recapitulations of the causal factors (direct, contributing, and root causes) of the accident

determined by the analysis of facts. [DOE G 225.1A-1]

87.

CONDITION. Any as-found state, whether or not resulting from an event, that may have

adverse safety, health, quality assurance, security, operational or environmental implications.

A condition is more programmatic in nature; for example, an error in analysis or calculation,

an anomaly associated with design or performance, or an item indicating a weakness in the

management process are all conditions. [DOE M 232.1-1A]

88.

CONDITION ASSESSMENT SURVEY. A periodic inspection of capital assets using

universally accepted methods and standards. [DOE O 4330.4B] [EH62dd1]

89.

CONFINEMENT AREA. An area having structures or systems from which releases of

hazardous materials are controlled. The primary confinement systems are the process

enclosures (glove boxes, conveyors, transfer boxes, other spaces normally containing

hazardous materials), which are surrounded by one or more secondary confinement areas

(operating area compartments). [DOE O 6430.1A]

CONFINEMENT BARRIERS.

Primary confinement. Provides confinement of hazardous material to the vicinity

of its processing. This confinement is typically provided by piping, tanks, glove

boxes, encapsulating material, and the like, along with any offgas systems that

control effluent from within the primary confinement.

Secondary confinement. Consists of a cell or enclosure surrounding the process

material or equipment along with any associated ventilation exhaust systems from

the enclosed area. Except in the case of areas housing glove-box operations, the

area inside this barrier is usually unoccupied (e.g., canyons, hot cells); it provides

protection for operating personnel.
