I'm not a domain expert, but I believe that figure is the total amount that's created, not separated. I.e. this language: - "Ni et al (1) estimate that one CANDU 6 reactor can produce 130 g of tritium per year, but this is based on physics, not actual production data." https://scientific-publications.ukaea.uk/wp-content/uploads/CCFE-PR1767-1.pdf https://scientific-publications.ukaea.uk/wp-content/uploads/... ref.

Heavy-water reactors weren't optimized to produce tritium; it was an unwanted contaminant.
