TECHNOLOGICAL STEAM-REHEATING CHANNEL OF STRAIGHT-FLOW WATER-WATER NUCLEAR REACTOR Russian patent published in 2013 - IPC G21C3/00 

FIELD: power engineering.

SUBSTANCE: channel comprises a cylindrical body 1 with an inlet 2 in the upper part of the body for water and an outlet 3 in the upper part of the body for reheated steam, a distribution grid 4 for water, ball fuel elements 5, fixed in spherical holes 6 of fixing plates 7. Ball fuel elements 5 with fixing plates 7, assembled into a packet in the lower part of the body 1, form an area 8 for heating of water and formation of a double-phase saturated steam and water mixture, and ball fuel elements 5 with fixing plates 7, assembled in a packet in the upper part of the body 1, form a steam-reheating zone 9. In the middle part of the body 1 above the zone 8 of water heating there is a membrane 10 installed to collect the steam-water saturated mixture and forming a circular channel 11 with a separator 12, on the curvilinear inner surface at the side of the water heating area 8 of which there are water-diverting collars 13, which divert water flow 14 into tubular channels 15, and holes 16 for passage of the flow 17 of saturated steam.

EFFECT: expansion of functional capabilities by intensification of heat exchange and higher stability of channel operation.
