HOMOGENEOUS FAST REACTOR-RESERVOIR Russian patent published in 2005 - IPC

FIELD: the invention refers to nuclear technique particularly to construction of homogenous fast reactor on suspension.

SUBSTANCE: the homogeneous fast reactor-reservoir is characterized thereby that thermal contour working on natural circular fine-dispersed dredge of the fuel particles in liquid metal carrier contains an active zone of variable volume, has under critical stagnant zones with an open surface also having a reserve volume. Together with refrigerating part of the liquid metallic refrigerating contour it is contained inside closed volume limited by an external body of the reactor. Liquid lead and its alloys are used as carrier of fuel particles in a fuel contour and thermal carrier in the refrigerating contour and mixture of raw and fissionable species serves as a fuel for starting feeding. The rising section of the fuel contour is fulfilled in the form of a vertical cylindrical housing with inputs from below and outputs from above, lateral openings connecting the housing relatively with assembled and distributed collectors of ramified system of thermal tubes, paved together with the tubes if the refrigerating contour in space between the external wall of the housing and the inner wall of the reactor's body. An ousting plug is immersed in the upper part of the housing with a gap for passing of suspension. The plug is fulfilled with possibility of vertical displacement relatively to the wall of the housing, and the vacant lower part of the housing serves as active zone the volume of which is determined by the position of the plug. The external body of the reactor is fulfilled in the form of high-fusing bucket closed with a protective cover with openings for loading and other technological channels which are designed for keeping non-volatile radioactivity at temperatures no higher than the point of boiling of the lead and located inside the protective structure fulfilled of heat resistant cement-basalt or similar other mineral foundation.

EFFECT: allows to insulate the fuel contour inside closed volume.
