WebThe graphite pile in the reactor was in the form of a vertical cylinder 10.2 m high and 15.7 m in diameter. It consisted of a network of columns locked together by mortise and tenon joints. The pile weighed no less than 2,680 tons. The four CO 2 -steam heat exchangers were single tube cross circulation types. WebAt the bottom of each boiler, large gas circulators pump high-pressure carbon dioxide gas through the graphite core and up through the fuel channels, where the gas picks up the heat generated by the nuclear reaction. As it passes through the boiler, the gas gives up its heat to the water in the boiler tubes.

WebAug 2, 2024 · The high-temperature gas-cooled reactor (HTGR) is fueled by a composite of graphite and fuel-bearing microspheres. We have two competitive designs for this type of reactor: A “pebble bed” German system_ this type uses spherical fuel components, 60 mm (2.5 inches) in diameter, including a graphite-and-fuel mixture covered in a graphite shell. WebDuring reactor operation, neutron flux and thermal gradients; in the graphite components, including the reflector, can lead to component deformations, bowing and the build up of significant shrinkage and thermal stresses.
