8 Gascooled nuclear power plant with closed Brayton cycle combined with ORC Nowadays, more interest for cost effective, fuel efficient and safer reactors has caused investigation on helium‐ cooled nuclear reactors. The gas turbine‐modular helium reactor (GT‐MHR) is one type of helium‐cooled nuclear reactors (Mortaza Yari, S.M.S. Mahmoudi, 2010). These reactors are designed to be connected to a closed Brayton cycle. As depicted in Figure 20, after that helium works as a coolant of reactor core, it poses enough temperature (point 1) to run a gas turbine cycle in order to produce electricity. This gas turbine cycle has turbine (process 1‐ 2), a low pressure (process 5‐6) and high pressure compressor (process 8‐9). The compression occurs in two stages in order to decrease input power to compressors. Helium after intercooler between low pressure and high pressure compressors (Point 8) shall be cooled down to 26 °C (between two stages of compression in the cycle). This cooling process has about 300 MWth waste heats provided 100 – 150°C temperature at inlet of intercooler. Moreover, pre‐cooler of helium (Process 5‐6) before low pressure compressor has an amount of waste heat. Intercooler and pre cooler waste heat make enough justifications for the ORC usage in the cycle. In Figure 19 it has been shown how two ORC units will fit in the cycle. One ORC evaporator will use intercooler and the other use pre‐cooler waste heat to produce extra amount of power. Adding ORC to the system will decrease the exergy loss of system about 5% and will improve the efficiency by about 3% (Mortaza Yari, S.M.S. Mahmoudi, 2010).39 39 Mortaza Yari, S.M.S. Mahmoudi.

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
