The costs are lower than that of the helium primary system, which clearly indicates the benefit of using lead alloy as a primary system coolant. As for the re-heat the same conclusion can be drawn as for the helium indirect cycle. Since the cost reported here includes only the additional cost of the intermediate heat exchanger and not the costs of adding the additional loop for the re-heat stage the savings achieved here indicate that use of re-heat is not economically attractive as pointed out in section 7.4.3. In addition in the case of lead alloy cooled reactors the intermediate heat exchangers are located inside the vessel. Re-heat increases the number of penetrations through the vessel and the additional volume of re-heaters may not fit inside the reactor vessel. Placing them outside would introduce a significant capital cost increase. A final answer would require a very detailed economic analysis. The reason why re-heat is regularly used at fossil stations is that the fuel cost is a significant portion of the electricity generating cost and plant efficiency can reduce this cost. However, this is not the case for nuclear plants. Another reason is that the pressure difference across steam cycle turbines is very high. 178 IHX Cost ($)PDF Image | Supercritical Carbon Dioxide Cycle for Next Generation Nuclear Reactors

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
