DEVICE FOR FLOW RATE STABILISATION Russian patent published in 2010 - IPC G05D7/01 G01F15/00 G01F1/34 

FIELD: power engineering.

SUBSTANCE: invention is intended to stabilise flow rate of liquid coolant in channel at the inlet to imitator of nuclear power plant reactor core fuel cassette, preferably of VVER-1000 reactor type. Device comprises hollow reservoir installed on stands 2 inside the channel, coaxially to its longitudinal axis, and its shell along longitudinal axis of reservoir has two through holes. Reservoir is drop-shaped and is perforated in largest section. Inside reservoir, in its front through hole, there is bushing 6 installed with holes in side surface.

EFFECT: invention provides for profiling of liquid flow speeds field in nuclear reactor core.
