[en] The evaluation of alternate steam cycles for the steam cycle HTGR with the ultimate selection of steam reheat, electric-driven circulator has been completed and is documented. The results of the evaluation can be summarized as follows: (a) the result of the tangible comparison shows insignificant differences between configurations, (b) the results of the intangible comparison are in favor of the non-gas reheat electric-driven circulator Configuration A. Configuration A has been recommended as the steam cycle configuration to pursue. The evaluation was different from previous evaluations in that increased emphasis was placed on the factors of (a) safety and licensing, (b) availability, (c) operability, (d) risk, (e) design development, and (f) schedule, relative to capital and fuel costs which were also included in the evaluation. The evaluation was accomplished by developing and documenting three conceptual designs. These designs, and where necessary, perturbations of the designs, were evaluated both for tangible and intangible assessments. The three base case designs have the following major features: Configuration A--Steam reheat, electric circulator; Configuration B--Steam reheat, high pressure steam-driven circulator; and Configuration C--Gas reheat, intermediate pressure steam-driven circulator
