Criticality and shielding calculations for nuclear fuel cycle facilities

 

  • Criticality calculations to demonstrate the safe handling of nuclear fuels in the nuclear fuel cycle facilities.

  • Shielding calculations to demonstrate compliance with legally prescribed dose limits when handling radioactive materials.

 

Our service packages

Using state-of-the-art programmes such as MCNP, SCALE, MICROSHIELD etc. and drawing on our decades-long experience, we support our customers in all tasks relating to shielding and criticality safety issues; the applicable regulations (such as KTA 3602, StrlSchV etc.) are taken into account.

 

Criticality evidence for:

  • Spent fuel pools

  • Transport and storage casks

  • Cooling racks for MOX fuel elements

  • Fuel fabrication facilities

  • Domestic and foreign reprocessing plants

  • Specific spent fuel pool configurations, e.g. to ensure criticality safety during decommissioning and boron removal (even for boron-free storage)

Shielding calculations for:

  • Interim storage facility

  • Containers for the transport and storage of operational waste and spent fuel elements
