Materials and applications Plant construction and design Nuclear island Nuclear reactors use nuclear fuel which undergoes a fission process – the splitting of atoms – to produce heat. Using light water as primary fluid, the heat is transported either directly to the turbine or to a steam generator interfacing the primary and a secondary loop. Resistance to Primary Water Stress Corrosion Cracking (PWSCC) is one of the most important requirements for the materials used in the steam generator and the related tubing systems. Only very few materials meet these high requirements: VDM Metals delivers...

Plant operation Fuel rod assemblies Fuel rods are usually bundled into fuel rod assemblies. These fuel structures need to maintain their shape and integrity over a period of several years within the reactor core, thereby preventing the leakage of fission products into the reactor coolant. The physical structures for holding the fuel rods are therefore engineered with extremely tight tolerances. They must be resistant to chemical corrosion, high temperatures, large static loads, vibration, fluid and mechanical impacts. Yet they must also be as neutron-transparent as possible. Spacer grids and fasteners...
