IMPROVEMENTS IN AND RELATING TO NUCLEAR REACTORS
Patent

OSTI ID:4010476
A reactor control device is described in which a neutron poison, liquid or solid, undergoes a change to the vapor phase at a predetermined danger temperature. The change of phase increases the surface-to-mass ratio of the poison, thereby reducing the reactivity of the reactor. The poison may be contained within a hollowed fuel element or in the moderator; if Hg is used as a poison, a container is provided that will not rupture until the Hg pressure has built up to the danger temperature value. Means are provided for removal of the poisoned elements. (T. F.H.)
