e that economic cost data have been developed for the alternatives and that these data are adequate for a benefit-cost balancing and comparison with the proposed system. This portion of the evaluation procedure should be conducted with the assistance of appropriate ESRP 10.4 reviewers. The reviewer should complete the economic and reliability portions of Table 9.4.1-1. On the basis of the completed table, the reviewer should balance and compare benefits and costs of the environmentally preferable alternative(s) with those of the proposed system. When an environmentally preferable alternative can be shown to have the same benefits in terms of electrical output as the proposed system with comparable reliability and at the same or lesser economic costs, the reviewer may conclude that the alternative should be considered an alternative to the proposed system. For those cases in which the benefits of the alternative are less than those of the proposed system (e.g., lower electrical output or decreased reliability) or if economic costs are greater than those of the proposed system, a conclusion that the alternative should receive additional consideration should involve consultation with the EPM and with the appropriate ESRP Chapter 4.0 and 5.0 reviewers. If this consultation establishes that the benefit- cost balances of such alternatives are no more than equivalent to the proposed system, the alternatives should not receive further consideration. When alternatives have significantly decreased benefits or increased economic costs, they should be rejected for any further consideration as alternatives to the proposed systems. October 1999 9.4.1-11 NUREG-1555 IV. EVALUATION FINDINGS This review should accomplish the following objectives: (1) description of alternative heat dissipation systems considered and results of the staff’s analysis of these alternatives, (2) presentation of the basis for the staff’s analysis, and (3) presentation of the staff’s conclusions
