hydrogen cooled nuclear reactor

A new molten salt reactor design can scale from just 50 Megawatts electric (MWe) to 1,200 MWe, its creators say, while burning up nuclear waste in the process. “We can divert a varying fraction of the steam from the turbine to drive industrial process such as the production of hydrogen, ammonia or other chemicals. Through the use of techniques to upgrade the temperature of that steam we can couple water-cooled reactor technologies, such as NuScale, to higher temperature processes.” 2 ... VHTR—Very High Temperature Gas-Cooled Reactors; LWR – Light Water Reactors . The hydrogen contributes to decreased efficiency, as well hydrogen embrittlement and swelling of the nuclear metals; that is a reduction n the power output and a shortening of the reactor life. Going forward, next generation high-temperature SMR designs could produce hydrogen at greater efficiency. The Gas Cooled Reactors (GCR) can be split into a bunch of different versions. Next Generation reactors. Zacariah Heim February 21, 2020 05:07 AM In heavy water, hydrogen is replaced with the Deuterium isotope. The first reactors built were the KIWI reactors: a series of non-flyable engines designed to test the physics of hydrogen-cooled reactor designs. Like other helium-cooled reactors which have operated or are under development, GFRs will be high-temperature units – typically 800-850°C. KIWI-A operated at a modest 100 MW, and its successor KIWI-B ran at a ten times this power. Gas-cooled fast reactor (GFR). The use of hydrogen in the production of transport fuels from crude oil is increasing rapidly. Hydrogen is widely seen as a future transport fuel, In the short term, hybrid electric vehicles have potential to increase the demand for base-load power from grid systems. They employ similar reactor technology to the VHTR, suitable for power generation, thermochemical hydrogen production or … Very high temperature reactor (VHTR): helium-cooled reactor moderated by graphite with an open uranium fuel cycle. It may be adapted to the production of hydrogen. The fundamental concept behind nuclear-hydrogen system is to use the heat of the reactors to generate hydrogen via thermochemical or electrochemical processes. ☢️ You like nuclear… High-temperature gas cooled reactors, helium cooled reactors, and molten salt reactors, offer high temperature process heat which enhances the efficiency of hydrogen production, O'Brien noted. Nuclear physics are fascinating, but we already are sent all the power we can use from the reactor that is 93,000,000 miles from the nearest elementary school. The selection of hydrogen technologies (to be coupled to nuclear power reactors) greatly depends on the type of the nuclear power plant itself. I have only included these two: The nuclear hydrogen project Reactor for Process Heat, Hydrogen, and Electricity Generation Integrated Project (RAPHAEL IP) carried out during 2005–10 consisted of 33 partners from 10 countries, with the main objectives a study of advanced gas-cooled reactor technologies needed for industrial reference designs. Super critical water-cooled reactor (SCWR): A reactor cooled by high pressured water and high temperature that works beyond water’s thermodynamic critical point. In other words, a hydrogen production plant is combined with an advanced nuclear power plant, which serves as … 4 . High Temperature Nuclear Reactors for Hydrogen Production Carl Sink Advanced Reactor Technologies Program Manager Office of Advanced Reactor Technologies (NE-74) November 18, 2014 .
