Embodiments of the present application relate to the field of nuclear reactors, and in particular to a thermionic reactor. The thermionic reactor provided by embodiments of the present application comprises: a thermionic reactor body configured to convert heat generated by the thermionic reactor body into electrical energy; an electromagnetic pump configured to drive circulation of a coolant of the thermionic reactor body; and a start-up power supply configured to drive the electromagnetic pump to drive circulation of the coolant before the thermionic reactor body is operated. Since the start-up power supply is configured to drive the electromagnetic pump before the thermionic reactor body is operated, self-power supply of the electromagnetic pump during the reactor start-up process can be achieved, which does not rely on an external power supply and drives the coolant to flow to take away excess heat of the thermionic reactor body; after the reactor start-up is completed and a normal operation stage is entered, the start-up power supply can continue to supply power to the electromagnetic pump and other system devices.

A portable nuclear power system includes a nuclear reactor. The nuclear reactor includes a core comprising a vessel housing a nuclear fuel that produces radiation, a sleeve of a high temperature moderator material disposed circumferentially about the core, and a neutron screen disposed circumferentially about the sleeve. The portable nuclear power system generates electricity using heat received from the nuclear reactor and has one or more cooling units in thermal communication with the electricity generating unit.
