[en] Comparative economic analyses for dry-cooled 1000 MW(e) nuclear power plants using three different turbine-generator designs were performed. The analyses indicated that, if nuclear fuel costs continue to increase, a modified conventional unit with exhaust pressures up to 8 in. Hg absolute would be more economical than a high-back-pressure unit (15 in. Hg absolute). Since the modified conventional unit might also be feasible for evaporative and wet/dry cooling, a utility could place an order for the turbine-generator before reaching a final decision on the type of cooling system to be used
