Full Title

Full titles differ between systems:

IPC:

Reactor types > Thermal reactors > Heterogeneous reactors, i.e. in which fuel and moderator are separated > moderator being highly pressurised, e.g. boiling-water reactor, integral-superheat reactor, pressurised-water reactor > moderator and coolant being different or separated

CPC:

Reactor types > Thermal reactors > Heterogeneous reactors, i.e. in which fuel and moderator are separated > moderator being highly pressurised, e.g. boiling water reactor, integral super-heat reactor, pressurised water reactor (G21C1/22 takes precedence) > moderator and coolant being different or separated

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.
