WebThe reactor core is an assembly of fuel element bundles or subassemblies that contain the fuel rods. The cladding materials serve to maintain the design configuration of the fuel rods and to protect the fuel from the coolant medium. The cladding also prevents the fission products from entering the primary system of the reactor.

WebThe AVR reactor has certain basic characteristics that are similar to those of the other helium-cooled reactors. These include (1) the use of graphite both as structural material and moderator, (2) (U, Th) C 2 fuel particles coated with pyrolytic carbon coatings and dispersed in a graphite matrix, and (3) high gas temperatures that allow the use of modern steam … The simplest type of reactor is a batch reactor. Materials are loaded into a batch reactor, and the reaction proceeds with time. A batch reactor does not reach a steady state, and control of temperature, pressure and volume is often necessary. Many batch reactors therefore have ports for sensors and material input and output. Batch reactors are typically used in small-scale production a…
