The report describes early conceptual studies of a 2-loop intercooled 3000 MW(t) plant which, together with existing conceptual designs of a 3-loop intercooled 3000 MW(t) plant, can be compared with designs being studied by the HHT Project. The objective of this effort is to determine a basis for a common development program and demonstration plant. The 2-loop intercooled design is compared to the 3-loop nonintercooled 300 MW(t) reference design of General Atomic Company. The turbomachine increased in rating from 400 to 620 MW(e) and in length from 37 to 52 ft. The larger heat exchangers required caused the PCRV diameter to increase from 118 to 128 ft and the height from 111 to 125 ft. The system pressure losses increased from 7.15 to 10.60%. The plant efficiency increased from 39.6 to 41.2%. Initial indications are that the increase in efficiency roughly balances the increased cost of the reactor turbine system.
