2.7

S AFETY S UPPORT S YSTEMS

This section identifies and describes the principal systems that perform safety

support functions (i.e., safety functions not part of specific processes). State the

purpose of each system and provide and overview of each system, including

principal components, ope rations, and control function. Examples of systems

under this heading might include fire protection, criticality monitoring, radiological

monitoring (e.g., air monitoring, contamination prevention), chemical monitoring

(e.g., hydrogen concentration monito ring), effluent monitoring, etc.

Note: This section is designed to organize the presentation of information, not to

designate any special class of equipment.

2.8

UTILITY D ISTRIBUTION S YSTEMS

This section provides a schematic outline of the basic utility distribution systems,

including a description of the offsite power supplies and onsite components of the

system. Details of systems are given, to the level necessary, for understanding the

utility distribution philosophy and facility operations.

2.9

AUXILIARY S YSTEMS AND S UPPORT F ACILITIES

This section provides information on the remaining portions of that facility that

have not been covered by the preceding sections and which are necessary to

create a conceptual model of the facility as it pertains to the hazard and accident

analyses
