high temperature gas reactor

Electron microscope image of dislocation particle interaction in Alloy 617 put under stress at 750°C. HTGR uses TRISO coated particle fuel, full ceramic core structure, and helium as coolant. This paper provides a summary of the design and its main attributes. 710 high-temperature gas reactor program summary report. Engineer-Poet says. Ramana has written a useful summary of the troubled history of high-temperature gas-cooled reactors (HTGR) including the pebble-bed reactor sub-type. Core . 80% of reactor thermal power can be utilized by a cascade energy system for hydrogen production, power generation and desalination. The high-temperature gas-cooled reactor (HTGR), as mentioned above in Fuel types, is fueled by a mixture of graphite and fuel-bearing microspheres. In particular this report addresses the comments provided by INL and documented in TEV-1463 Rev. "Modular High-temperature Gas-cooled Reactor Power Plant" introduces the power plants driven by modular high temperature gas-cooled reactors (HTR), which are characterized by their inherent safety features and high output temperatures. Figure 1 : Key industrial process heat applications and operational temperature range for light water reactors ( LWR ) & high temperature reactors ( HTR ) History. The HTR has more than 50 years of somewhat chequered history behind it. 0, (INL, 2012). High-temperature gas-cooled reactors (HTGRs) also known as very-high-temperature reactors (VHTR) are Generation IV reactors that can operate at very high temperatures and use gas as a coolant. My analysis indicates that breeding is a possibility in high temperature gas reactors using TRISO particle fuel, but even a very high conversion ratio may lead to extended life cores. The VHTR is a next step in the evolutionary development of high-temperature gas-cooled reactors. Assembly . The high-temperature gas-cooled reactor demonstration project at Shidaowan nuclear power plant. In particular this report addresses the comments provided by INL and documented inTEV-1463 Rev . [Photo/CNNC] A major milestone was achieved at the high-temperature gas-cooled reactor, also known as the HTGR project -- located at the Shidaowan nuclear power plant in Weihai city, in East China's Shandong province -- according to local officials. The high-temperature gas reactor also has excellent safety features and can generate heat of 900°C or higher, which is significantly higher than that of conventional light-water reactors. 3-4 cm ~10 ~30. High temperature gas reactors have the unique ability to use the Brayton cycle. From 2006 through 2009 he was the program manager for the Nuclear Hydrogen Initiative, coordinating DOE efforts to develop high temperature water-splitting technologies to take advantage of HTGR outlet temperatures. Relative Size (mfp) of Fuel and Core. APPLICATIONS UP TO 1100 °C Based on over 40 years of development, experience and success, SCHWING manufactures specific high-tempera-ture reactors based on the fluidized bed technology for the thermo-chemical treatment of powders with reaction gases in … In the past, both Germany and the United States spent large amounts of money to design and construct HTGRs, four of which fed electricity into the grid. TRISO Fuel Pellet(Fresh) is the fuel used in this setup. English IAEA-TECDOC-CD-1674 978-92-0-186810-7. These designs are now referred to as High Temperature (Gas) Reactors – HTR or HTGR. The Japan Atomic Energy Agency (JAEA, former Japan Atomic Energy Research Institute) began research and development of high temperature gas-cooled reactors for the multi-purpose use of nuclear / thermal energy in 1969. A high temperature gas-cooled reactor, or HTGR, is an inherently safe, modular, underground helium-cooled nuclear reactor technology. Summary. Volume I. The first nuclear reactor demonstrating the feasibility of a sustained and controlled chain reaction was built in Chicago in 1942. The High Temperature Gas-cooled Reactor: Safety considerations of the (V)HTR-Modul ©EU. HTRs have the potential to be adopted near demand side to supply both electricity and process heat, directly replacing conventional fossil fuels. With the single phase Brayton cycle efficiencies of 48% can be easily achieved. 2 China Coal Technology Engineering Group Chongqing Research … Declassified 6 Sep 1973. 0, (INL, 2012). The very high temperature reactor is cooled by flowing gas and is designed to operate at high temperatures that can produce electricity extremely efficiently. Full Record; Other Related Research; Abstract. Within GIF, Mr. It was first developed for use in high-temperature gas reactors, but can also be applied to molten salt and liquid metal reactor designs. Generation Nuclear Plant Project, the DOE initiative to develop and demonstrate a high temperature gas-cooled reactor (HTGR). The first serious thinking about achieving high temperatures in a gas-cooled reactor can be attributed at Harwell to Stefan Bauer, who, in the years 1948–1949, was considering a bed of beryllium oxide balls coated with uranium and recoated with beryllium oxide as fuel.
