The HICB review of each life-cycle activity should address the review points covered in Sections III.A and III.B. The Staff's review emphasis should be commensurate with the safety significance of the given system Rev. 4 — June 1997 SRP 7.0-4 or aspect of a system's design under review. Probabilistic risk assessments (PRAs), such as those conducted under the Individual Plant Evaluation program or required as part of applications under 10 CFR 52, provide information that may prove helpful in determining the appropriate level of review. Review scope should be coordinated with secondary review branches as discussed in Section V below.

Chapter 1 For familiarization with the general operation of the plant, both safety and non-safety aspects. Chapter 2 For familiarization with environmental conditions and natural phenomena hazards that could affect I&C systems. Chapter 3 For a general understanding of the principal architectural and engineering designs of those structures, components, equipment, and systems important to safety.
