Question 2

Appendix A to Subpart B to Part 830—General Statement of Safety Basis Policy (Section G)

How does the Safety structures, systems, and components, that require formal definition of minimum acceptable performance, get defined in the documented safety analysis?

Answer 2

This is accomplished by first defining a safety function, then describing the structure, systems, and components, placing functional requirements on those portions of the structures, systems, and components required for the safety function, and identifying performance criteria that will ensure functional requirements are met. Technical safety requirements are developed to ensure the operability of the safety structures, systems, and components and define actions to be taken if a safety structure, system, or component is not operable.
