  • Intertube thermal conductance rate limiting device
    Patent number: 5171521
    Abstract: The invention provides an intertube thermal conductance rate limiting device for a nuclear reactor fuel channel having an inner pressure tube and outer calandria tube. The device comprises a wire screen placed in the annular region between the pressure tube and calandria tube which limits the contact area between the two tubes. By reducing the contact area, the screen limits the thermal conductance rate to the calandria tube. This reduces or eliminates the potential for film boiling or "dryout" of the calandria tube.
