5.2

This section lists regulatory design criteria and

guidelines considered relevant to the design and maintenance of

nonsafety class instrumentation and control (I&C) systems in

nuclear facilities.

Such facility I&C systems typically include

process control systems and data acquisition and display systems

not part of facility safety class I&C systems or protection sys-

tems. Where the operation or functional condition of a nonsafety

class I&C system and/or component interfaces with or otherwise

impacts the safety function of a safety class I&C system and/or

component, the criteria identified in 5.1 must also be considered

for design and maintenance activities.
