A fast nuclear reactor is provided with thermionic converters embedded in separate, subcritical, fuel masses and reactivity is controlled by varying the separation of the masses. The core is formed of subcritical fuel discs, 1, each of which contains thermionic emitters 3 and collector electrodes 4. The space between 3 and 4 contains caesium vapour fed through lines 11a, 11b. Coolant is supplied through lines 12a, 12b, 16a, 16b. The electrical leads 8, 10 may be connected in series or parallel. Each fuel disc has a metal casing 2 and thermal insulation 7. Coarse reactivity control is effected by variation of the disc spring.
