WebFeb 16, 2024 · While the design principles are similar for non-chemical reactors, these types of vessels are more simplistic in their operations. Chemical reactors are at the heart of any process system. This is the … 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.
