INNOVATIVE CERAMIC BUNDLE FUEL ELEMENT

The step from the basic components to a bundle fuel element is demonstrated for the CANDU reactor.

On the left side you see the standard CANDU fuel element:

  • outer diameter 10 cm
  • length  50 cm
  • fuel in metallic tubes
  • assembled with a metallic skeleton.

According to our design, fuel-filled capsules or compacts are armoured with fibre braids to rods. Then the rods are assembled with a ceramic skeleton to a bundle fuel element.

A fibre braid jacket improves the overall mechanical stability.
