Jet engine flow instead of nuclear reaction: energy for heat and electricity

Instead of heat from the nuclear reaction, at 300° Celsius, heat is used in the case of coupled turbojet from the nozzle of a gas turbine, in which the enormous exhaust gas flow, at up to 1200° C. Flows onto the steam boiler, which almost doubles the thermal efficiency dependent on the maximum temperature of the water vapor! Generating heat from the nozzle of a turbojet (gas turbine) is possible with a jet engine: such a jet engine is, for example, for a power plant that has an output of 340 [MW]) is 13 meters long, and has a circumference of about 5 meters. The exhaust gas flow of 820 kg/second has an average temperature of 625°. A climate-friendly, regenerative fuel is used for this purpose: fatty acid methyl ester (FAME). This consists of compounds of a fatty acid with an alcohol (methanol). A mixture of several types of FAME products, consisting of vegetable (rapeseed oil) or animal fats (lard) and alcohol (methanol) is already used as fuel for diesel engines (biodiesel).
