G21D NUCLEAR POWER PLANT
Introduced: September 1968
Description
G21D covers the overall design, construction, and operation of nuclear power plants as integrated systems for generating electrical power through nuclear fission. This includes plant layout, control systems, safety mechanisms, heat transfer arrangements, and the interconnection of reactor vessels with steam generators, turbines, and auxiliary systems. The classification encompasses both pressurized water reactors (PWR) and boiling water reactors (BWR) configurations, as well as related plant engineering aspects. Excluded are detailed aspects of reactor cores themselves (G21C), radioactive waste handling (G21F), and non-power nuclear installations.
IPC and CPC are identically structured here. All 5 subcodes exist in both systems.
3 shared codes have differing titles between IPC and CPC.
