CFD simulation of partial channel blockage on plate-type fuel of TRIGA-2000 conversion reactor core
A nuclear reactor cooling system that has been operating for a long time can carry some debris into a fuel coolant channel, which can result in a blockage. An in-depth two-dimensional simulation of partial channel blockage can be carried out using FLUENT

FUEL CHANNEL VARIABLE ORIFICE DESIGN [PDF]
A design analysis of a variable adjustable orifice that can be used on all fuel channels is presented. With an adjustmert range of 1/4 turn the flow can be controlled over the range 9.9 to 36.9 lb/sec with a constant sensitivity of 5.85 deg F/deg. rot. for DELTA T = 400 deg F. Temperature sensitivity can be reduced by increasing the adjustmert range; a

Sub-channel CFD for nuclear fuel bundles [PDF]
This paper presents a novel Computational Fluid Dynamics (CFD)-based sub-channel framework for nuclear power plants, which combines the advantageous features of modern CFD and traditional 1-D sub-channel codes. The new method is capable of producing CFD-level 3-D results with locally desirable refinement when coupled with embedded resolved models, but ...
