G21C1/00Reactors

G21C1/02Fast fission reactors G21C1/022Characterised by the concept and properties of the core G21C1/024where the core is divided in zones with fuel and zones with breeding material G21C1/026Reactors not needing refueling, i.e. reactors of the type breed-and-burn G21C1/028cooled by a pressurised coolant G21C1/03cooled by a coolant not essentially pressurised G21C1/04Thermal reactors; Epithermal reactors G21C1/06Heterogeneous reactors G21C1/07Pebble-bed reactors Reactors with granular fuel G21C1/08moderator being highly pressurised G21C1/082Reactors where the coolant is overheated G21C1/084Boiling water reactors G21C1/086Pressurised water reactors G21C1/09Pressure regulating arrangements G21C1/10moderator and coolant being different or separated G21C1/12moderator being solid G21C1/14moderator being substantially not pressurised G21C1/16moderator and coolant being different or separated G21C1/18coolant being pressurised G21C1/20moderator being liquid G21C1/22using liquid or gaseous fuel G21C1/24Homogeneous reactors G21C1/26Single-region reactors G21C1/28Two-region reactors G21C1/30Subcritical reactors; Experimental reactors with exception of swimming-pool reactors or zero-energy reactors G21C1/303Experimental and irradiation arrangements inside the reactor G21C1/306Irradiation loops G21C1/32Integral reactors, i.e. reactors wherein parts functionally associated with the reactor but not essential to the reaction G21C1/322wherein the heat exchanger is disposed above the core G21C1/324wherein the heat exchanger is disposed beneath the core G21C1/326wherein the heat exchanger is disposed next to or beside the core G21C1/328wherein the prime mover is also disposed in the vessel
