METHOD AND DEVICE FOR PRODUCING ELECTRIC POWER BASED ON HEAT DISTRIBUTED IN AN ACTIVE ZONE, AT LEAST, ONE HIGH-TEMPERATURE NUCLEAR REACTOR

摘要

For the generation of electricity from the heat developed in a nuclear reactor, a closed primary gas circuit contacts a gas with the reactor. A second gas is heated by exchange from the primary gas, to drive a gas turbine coupled to an electricity generator. The heated gas circulates in a closed circuit to drive the gas turbine. The heated gas is then used to evaporate water, to provide steam to drive steam turbine coupled to the electricity generator. For the generation of electricity from the heat developed at the heart (5) of at least one high temperature nuclear reactor (1), a closed primary gas circuit brings a thermal exchange or calorific gas into contact with the reactor heart. A second gas is heated by exchange from the primary gas, to drive at least one gas turbine (2) coupled to an electricity generator (4). The primary heat exchange gas is helium, and the heated gas comprises 50-70% helium and 50-30% nitrogen. The heated gas circulates in a closed circuit to drive the gas turbine. The heated gas, after driving the gas turbine, is used to evaporate water in at least one evaporator (12), to provide steam to drive at least one steam turbine (3a-3c) coupled to the electricity generator.
