associated with NPPs. Therefore, risk importance is taken into account when deciding which particular items to review and the depth of review necessary. This aspect of grading the review is discussed in Section II.C below and can be applied to both risk-informed and non-risk-informed submittals This chapter provides detailed examples of graded review criteria for several reviews: C Control room modifications (see Section II.B) C Modifications affecting human actions of high risk importance (see Section II.C.2) C Modifications affecting human actions of moderate risk importance (see Section II.C.3) C Modifications affecting human actions of lower risk importance (see Section II.C.4) Within these graded review criteria, the guidance is further tailored each specific review. The areas of review with respect to an applicant's submittal are based on: C An evaluation of the information provided by the applicant C The similarity of the associated HFE issues to those recently reviewed for other plants C The determination of whether items of special or unique safety significance are involved 18.0-5 Revision 2 - March 2007 Review Interfaces Other SRP sections interface with this section as follows: 1. Section 6.3 "Emergency Core Cooling System (ECCS)." Section 6.3 addresses the review of ECCS. Section III.19 discusses the review of operator manual actions that may be necessary during ECCS operation in accident sequences up through the time of long-term core cooling. Chapter 18 addresses important manual actions under the HRA element. Thus, the reviews of Section 6.3 III.19 and Chapter 18 should be conducted in a coordinated manner. 2. Chapter 7, "Instrumentation and Controls." Descriptions of HSI components and characteristics are addressed by both Chapters 7 and 18 reviews. As appropriate, the review results of one chapter should be considered in the review activities for the other chapter. 3. Section 13.1.1, "Management and Technical Support Organization."
