CPC Definition - Subclass G21D
This place covers:
Aspects of power plants which include, as a power generator, a nuclear fission reactor. Also power plants which convert the heat produced by the fission reaction into forms of energy other than electricity (e.g. mechanical energy).
Attention is drawn to the following places, which may be of interest for search:
Electric or magnetic analogue computers, e.g. simulators, for nuclear physics | |
Nuclear fusion reactors | |
Aspects related to nuclear fission reactors per se | |
Structural combination of fuel element | |
Control of nuclear reaction | |
Emergency protection arrangements structurally associated with a reactor; for rapid reduction of reactivity under fault conditions; for suppressing fires | |
Pumping arrangements for the coolant by means within the reactor pressure vessel | |
Obtaining electrical energy from radioactive sources | |
Nuclear explosives and their applications | |
Electrodynamic pumps | |
Thermoelectric elements per se |
