ix B of NUREG-0700, Revision 0, was provided as one source of guidance regarding these analyses. NUREG-0700 now focuses on guidance for the review of plant HSIs. The guidance has been updated twice to reflect changes in HSI technologies. NUREG-1764, addresses the human performance aspects of changes to HAs that are credited for safety, especially those involving changes in the licensing basis of the plant; e.g., use of manual action in place of an automatic action for safety system operations. Risk-informed guidance and acceptance criteria are provided for the review of licensee proposals addressing such modifications. The review method uses a graded, risk-informed approach and provides guidance for reviewing the human performance aspects of changes to plant systems and operations. Three HFE review levels are defined: high, medium, and low risk (called Levels I, II, and III). HAs are reviewed using human factors engineering criteria to evaluate whether the proposed HA can be reliably performed when called upon in the plant. HAs in the high-risk level receive a detailed review and those in the medium-risk level receive a less detailed review that is commensurate with their risk. For HAs falling into the low isk level, minimal (or no) human factors review is performed. Thus, the HFE review process presented in this SRP chapter incorporates guidance from all three documents. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant's evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 18.0-25 Revision 2 - March 2007 The applicant should submit review materials for each review area. RG 1.206 provides guidance to DC and COL applicants
