Design and fabrication of optimal supporting spacer grids for bowed and/or ballooned heater rods tests
CHALLENGING SIMULATION HEATER RODS
Direct simulation heaters with different profiles (uniform, cosine, skewed (top peak, bottom peak, double peaks)), different materials, length, dimensions, and peaking factors:
Flow Instability Tolerant Simulation Heater (FITSH) :
|
Non-Uniform
Simulation Heaters w/ Different Heater Lengths: 3 ft, 7 ft, 12, ft, and 14 ft 
|
ATF Simulation Heaters: ATF simulation heater rods with different coating material and different coating thickness to facilitate high flow, high flux, and high temperature simulation heaters for CHF tests with rapid temperature transient.
|
Simulation Chromium-coated
ATF Heater Rods for CHF Tests |
|
Simulation Guide Tube: Triple insulated simulation guide tube design with accurate prototypical hydraulic dimensions and triple protection to allow installation in a high current field together with other electrically heated rods for thermal-hydraulic tests.
Bowed Rods: proprietary bowed rod design to facilitate simulation of various localized rod bow phenomena with different location, degree, and shapes of bows.
