Nuclear Energy Generation TRIZ Cases
- Mechanical Seal Assembly for Remote Tubular Opening Repair
A stopper, strongback, and external fasteners seal inaccessible tubular openings after foreign material removal while limiting radiation exposure.
- Work-Hardened Tube Weld Assembly for Heat-Affected Zone Strength
Plastic deformation work hardens tube welds and buried heat-affected zones to restore base-material strength under high tensile and pressure loads.
- Remote Bolt Tensioning Carts for Nuclear Vessel Assembly
Modular tool carts automate bolt installation, tensioning, and removal around nuclear vessels, reducing manual intervention in radioactive underwater work.
- Baffle Bolt Repair Platform for Faster Reactor Vessel Replacement
A motor-driven repair platform repositions and engages reactor baffle bolts faster, cutting outage time during vessel maintenance.
- In-Core Instrument Drive Safety Circuit for Cover-Open Power Cutoff
A cover-mounted safety circuit cuts motor power when the housing is removed, preventing contact with rotating parts during maintenance.
- Polyethylene Pipe Resin Composition Against Brittle Fracture
A nonpolar liquid additive helps polyethylene pipe resin resist brittle fracture and stress cracking from minute defects and environmental exposure.
- Nuclear Vessel Bolt Handling With Self-Positioning Tool Carts
Self-positioning tool carts install, tension, remove, and store nuclear vessel bolts remotely in high-radiation underwater assembly.
- Vortex Flow Damper Venting for Stable Water Injection
An elevated pressure equalization pipe with an outgassing hole removes trapped air, preserving pressure offsetting and required water injection flow.
- FPGA SEU Detection for Particle Time-of-Flight Measurement
An FPGA user circuit flags SEU events fast enough for time-of-flight energy measurement and continuous SEU cross section analysis.
- Digital Control Rod Positioning With Redundant Sensor Channels
Redundant digital transducers replace analog sensing to deliver millimeter-level control rod positioning and fault-tolerant monitoring in nuclear plants.
- Flyback High-Voltage Pulse Generator for Fast Rise-Time Control
A flyback transformer and high-frequency switching cut power dissipation while delivering fast-rise high-voltage pulses with variable width.
- Digital Control Rod Drive Positioning With Redundant Sensor Channels
Redundant digital sensor channels replace analog rod drive control to verify position data and enable 3 mm control rod positioning.
- Safety I&C FPGA Circuit with Switch Matrix for Predictable Timing
A fixed FPGA core plus a programmable switch matrix preserves diagram-based safety I&C engineering while keeping timing predictable.
