sor and instrument channel power supplies may be used provided the possibility of common-mode failure is prevented. If the ATWS system is explicitly addressed as part of a D-in-D&D analysis, then that analysis provides the basis for the assessing the adequacy of diversity between the ATWS mitigation system and the RTS. Rev. 4 — June 1997 SRP 7.8-7 Therefore, separate evaluation of the ATWS mitigation system against the above eight diversity criteria is unnecessary if the D-in-D&D analysis is provided. Additional major design considerations that should be emphasized in the review of manual controls and displays are identified below. • The manual controls and displays should meet the criteria outlined in BTP HICB-19. In each safety review, the Staff should determine the elements of the design that require additional review emphasis. Typical reasons for such a non-uniform emphasis are the introduction of new design features or the utilization in the design of features previously reviewed and found acceptable. However, in all cases, the review must be sufficient to conclude conformance to the acceptance criteria, i.e., the requirements of the Code of Federal Regulations. IV. Evaluation Findings The Staff verifies that sufficient information has been provided and the review supports the following conclusions as stated in the SER: Evaluation findings applicable to any diverse I&C system: The NRC staff conducted a review of these systems for conformance to the guidelines in the regulatory guides and industry codes and standards applicable to these systems. The Staff concluded that the applicant/licensee adequately identified the guidelines applicable to these systems. Based upon the review of the system design for conformance to the guidelines, the Staff finds that there is reasonable assurance that the systems fully conform to the guidelines applicable to these systems. Therefore, the Staff finds that these requirements of General Design Criteria (GDC) 1 and 10 CFR
