A power plant having a closed gas-cooling circuit for the production of process heat to be transferred to a secondary circuit, comprising: (a) a vessel comprising a generally solid block of material; (b) a high-temperature reactor positioned within the vessel; (c) a plurality of heat exchanger units positioned about said reactor in the reactor in the vessel, the heat exchanger units comprising each a high temperature heat exchanger and a low temperature heat exchanger coupled serially therewith, each of the heat exchanger units being removably mounted in a vertically oriented shaft in the material; (d) first means for conducting a portion of a hot gas stream leaving the reactor to each of the high temperature heat exchangers where the hot gas is partially cooled by indirect contact with a working fluid in the secondary circuit; (e) second means for conducting said cooled gas from each of the high temperature heat exchangers to said low temperature heat exchangers coupled therewith where the gas is further cooled by indirect contact with the secondary circuit fluid; and means for returning said further cooled gas to the reactor from each of the low temperature heat exchangers by circulating the gas around the periphery of each respective heat exchanger unit.
