Fuel Elements TRIZ Cases
- Zirconium Alloy Surface Nanostructuring for Corrosion Resistance
Nanostructuring zirconium alloy surfaces to less than 100 nm grain size improves corrosion resistance without compromising mechanical properties.
- Thorium-Uranium Fuel Rods for Boiling Water Reactor Power Distribution
Varying thorium to uranium ratios in fuel rods reduces internal power peaking and reactivity variations without burnable absorbers.
- Nuclear Reactor Flow Control Assembly for Traveling Burn Wave Management
Variable hole alignment in the flow control assembly addresses fuel rod swelling and thermal expansion risks.
- FCM Fuel Reactivity via TRISO Kernel and SiC Matrix
Increasing TRISO kernel diameter and packing fraction boosts heavy metal mass to resolve reactivity deficits in CANDU reactors.
- Burnable Poison Coating on Nuclear Fuel Rod Cladding
Sprays burnable poison particles onto nuclear fuel rod cladding to form a protective oxide layer that prevents dissolution in aqueous reactor coolant.
- Convex Profile Jet Spouted Bed Reactor for CVD Fluidization
A jet spouted bed reactor uses a convex transition profile to stabilize fluidization and maintain consistent gas flow velocity.
- Multi-lobed Metal Fuel Rods for Enhanced Heat Transfer
Segmenting cylindrical fuel rods into multi-lobed metal structures increases surface area, resolving overheating risks while enabling higher power generation.
- Segmented Fuel Rods with Varying Diameters for Spacing Stability
A segmented fuel rod assembly uses varying diameters and spacer grids to maintain optimal rod spacing within a nuclear reactor core.
