Fuel Elements TRIZ Cases
- Backup Control Rod Positioning for Fast Reactor Void Reactivity
A backup control rod positioned above the core fuel region increases neutron leakage to reduce void reactivity in fast reactors.
- Twisted Metallic Band Spacer for Fast-Neutron Reactor Fuel Rods
A twisted metallic band spacer element maintains distance between fast-neutron reactor fuel rods while reducing metal consumption.
- Molten Salt Reactor Fuel-Salt Preparation System
Converting pelletized spent nuclear fuel into halide salt powder to reduce storage space requirements and eliminate long-term waste streams.
- Fuel Assembly Void Reduction via Partial Rod Placement
Outer partial-length fuel rods lower void fraction to enhance neutron moderation and burnable poison worth, improving shutdown margin.
- Fuel Element Thermo-Mechanical Modeling for Breed-and-Burn Reactors
Model predicts irradiation creep and swelling in breed-and-burn reactors, preventing fuel element distortion during high burn-up cycles.
- Axially Heterogeneous Fast Reactor Fuel Assemblies
Varying internal blanket thickness across radial zones flattens power density while increasing coolant outlet temperature for molten salt integration.
- Zr-Fe-Cu-Ta Alloy for Inert Matrix Nuclear Fuel
A Zr-based alloy with Fe, Cu, and Ta forms a ductile matrix surrounding fuel pellets.
- PCI Margin Calculation for Nuclear Reactor Loading Patterns
Calculates principal and secondary PCI margins to assess cladding stress in nuclear reactor fuel assemblies.
- Nuclear Fuel Rod Plenum Spring Assembly Spacer Design
A threaded spacer distributes plenum spring force across the top fuel pellet surface to maintain uniform pressure.
