FAST NEUTRON REACTOR Russian patent published in 2013 - IPC G21C1/02 

FIELD: power engineering.

SUBSTANCE: reactor 1 comprises: a reactor body 7, holding a reactor core 2 and a coolant 21; a support grid 13 of a reactor core and a partition 6 arranged on the support grid, which stretches upwards and surrounds the reactor core 2 at the side. Between the inner surface of the reactor body 7 and the partition 6 there is an intermediate heat exchanger 15, configured to cool the coolant 21 of the primary circuit, and an electromagnetic pump 14, configured to inject cooled coolant 21 of the primary circuit. The neutron protective shield 8, supported with the upper support board 29 on top is arranged below the electromagnetic pump 14. The upper support board 29 has an opening 29a. Between the protrusion 14b of the electromagnetic pump 14 and the upper support board 29 there is a mechanism 17 for direction of coolant configured to sent injected coolant 21 of the primary circuit from the electromagnetic pump 14 to the neutron protective shield via the opening 29a of the upper support board 29.

EFFECT: higher tightness of primary circuit coolant and simplified repairability.
