From water. High temperature electrolysis of alkaline solutions has been used for the industrial scale production of hydrogen (see Sable Chemicals) and there are now a number of small scale polymer electrolyte membrane (PEM) electrolysis units available commercially. The Very High Temperature Reactor. The term Very High Temperature Reactor (VHTR) loosely covers any reactor design with a coolant outlet temperature of °C or above. The term typically refers to the next step in the evolutionary development of high-temperature gas-cooled reactors (HTGRs). support very high temperature process heat applications, such as thermo-chemical hydrogen production. The indirect cycle design also eliminates the potential for contamination of the electricity generation and/or hydrogen production equipment by radionuclide carried within the .

NGNP Concept for Large-Scale Centralized Nuclear Hydrogen Production based on High-Temperature Steam Electrolysis NGNP / HTSE Conceptual Design Direct coupled to HTGR reactor for electrical power and process heat MWth reactor could produce ~85 million SCFD hydrogen . support very high temperature process heat applications, such as thermo-chemical hydrogen production. The indirect cycle design also eliminates the potential for contamination of the electricity generation and/or hydrogen production equipment by radionuclide carried within the . Very-High-Temperature Reactor (VHTR) Its high outlet temperature makes it attractive also for the chemical, oil and iron industries. Original target of outlet temperature 1 °C from VHTR can support the efficient production of hydrogen by thermo-chemical processes. The technical basis for VHTR is the TRISO coated particle fuel. Mar 07,  · Very High Temperature Reactor. The very high temperature reactor is cooled by flowing gas and is designed to operate at high temperatures that can produce electricity extremely efficiently. The high temperature gas could also be used in energy-intensive processes that currently rely on fossil fuels, such as hydrogen production, desalination. Very-high-temperature reactor. The VHTR is a type of high-temperature reactor (HTR) that can conceptually have an outlet temperature of °C. The reactor core can be either a "prismatic block" or a " pebble-bed " core. The high temperatures enable applications such as process heat or hydrogen production via the thermochemical sulfur–iodine cycle. Very High Temperature Reactor (VHTR) It will supply heat with high core outlet temperatures which will enable applications such as hydrogen production and process heat for the petrochemical industry. The reactor outlet temperature will be in the range of to degrees Celsius ( to . The Very High Temperature Reactor. The term Very High Temperature Reactor (VHTR) loosely covers any reactor design with a coolant outlet temperature of °C or above. The term typically refers to the next step in the evolutionary development of high-temperature gas-cooled reactors (HTGRs). From water. High temperature electrolysis of alkaline solutions has been used for the industrial scale production of hydrogen (see Sable Chemicals) and there are now a number of small scale polymer electrolyte membrane (PEM) electrolysis units available commercially. Coupling high temperature electrolysis or a thermochemical cycle to a high temperature nuclear reactor will provide the heat required without producing greenhouse gas emissions. Generation IV reactors are ideal for coupling to a hydrogen production plant (HPP) due to their inherent safety and very high lodr.info by: The first High Temperature Reactor with a closed He primary loop was proposed in in the US but never built. It featured a primary circuit (helium at MPa, – °C) coupled to a secondary Brayton power conversion cycle (air at MPa, –22 °C) leading to an expected power rating of 5 lodr.info by: 8.The Very High Temperature Reactor (VHTR) is a graphite-moderated, as hydrogen production and process heat for the petrochemical industry.
