Abstract

A nuclear fission reactor system (10) which comprises a nuclear reactor unit (12) having a fuel block (400) with a central axis (402) extending along the length of the fuel block (400) between a first surface (412) and a second surface (422). The fuel block (400) defines a plurality of fuel assembly chambers (404) which extend from an inlet opening (410) on the first surface (412) of the fuel block (400) to an outlet opening (420) on a second surface (422) of the fuel block (400). There are also provided a plurality of fuel assemblies (100). Each fuel assembly (100) comprises a fuel compact (200) which defines a flow passage (202) running from a flow inlet (204) provided at a first end (206) of the fuel compact (200) to a flow outlet (208) provided at a second end (210) of the fuel compact (200), the passage (202) defining an internal surface (222) of the fuel compact (200). A displacer element (300) is provided in the coolant flow passage (202) and mounted such that a clearance (212) is maintained between the internal surface (222) of the fuel compact (200) and the displacer element (300) to define an annular coolant flow passage (230). Each of the plurality of fuel assemblies (100) is located in a respective one of the plurality of fuel assembly chambers (404). At least one of the fuel assemblies (100) of the plurality of fuel assemblies (100) is configured to transfer heat to the coolant in its annular coolant flow passage (230) at a first rate; and at least one other of the plurality of fuel assemblies (100) is operable/configured to transfer heat to the coolant in its annular coolant flow passage (230) at a second rate.
