Calandria Tubes & Calandria Spools

Calandria tubes are a unique pressure vessel, seam-welded tube designed specifically for the CANDU reactor. The calandria tube acts as a secondary pressure containment device in the unlikely event of a pressure tube failure. The calandria tube is considered part of the fuel channel and also adds a degree of structural rigidity to the core.

CFM has manufactured virtually every calandria tube for CANDU reactors world-wide.

The calandria tube spools are short versions of the calandria tube. These are generally used for testing and validation purposes. The two ends of the spool are exactly representative of the ends on a full length calandria tube.
