Title: Improvements in or relating to nuclear reactors
Inventor: PARAVICINI THOMAS PITT DE
IPC: G21C1/20
Filed: 1964-10-16
Abstract: 1,114,709. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 14 Oct., 1965 [16 Oct., 1964], No. 42275/64. Heading G6C. In a nuclear reactor, boiling and superheating of the coolant is effected in separate sections of the core. The boiling section is self-critical while the superheating section is rendered reactive only when it is penetrated by a neutron flux from the boiling section. Control of the neutron movement from the boiling to the superheating sections is effected by a heavy water reflecting screen mounted between the sections. Both sections are moderated by heavy water filled callandria tanks. During starting, no vapour is available from the boiling section to serve as coolant in the superheater and reactivity in the latter is prevented by the reflecting screen. When vapour is generated it is passed into the superheater and the heavy water removed from the shield to effect reactivity. Reactivity control is effected by moderator level variation.
