Te Unique Maintenance Demands of CANDU Reactors

Candu reactors, a Canadian-designed pressurized heavy water reactor, differ fundamenally from liagt water designs. Instead of a single large pressure vessel, they use hundreds of horizonthal fuel channels with a calandria contening tendemy water moderator. This speled core, combine with on- power concenteling, provides outstanding neutron economity and fuel flexibility but also create applienges not fond in ther reactor tys.

Adding to the completity is te radiation environment. Tritium produced by neutron absorption in teavy water migrates into karbon steel systems, creating a contamination hazard that makes personnel entry into the reactor vault or primary coonant loop extremely controlled.

Thee industry has long sought to minimize human presence in high-radiation areas while maintaining thate data richness needd for advance d condition assessment. Remote monitoring has emerged as the naturaol answer, leveraging materials science, approxications, and acficial intelecence to bring te diagnostic center to a desk rather than a worker to a danger zone. Thee specific consistance demandes can bcasized into neinai key areas:
