Until the NRU reactor at Chalk River ceased isotope production in 2016 it processed a large share of the world's molybdenum-99, and its exit reshaped the supply chain described in the reactor record.","asOf":"2026-09-17","links":[{"label":"Official website","url":"https://www.nordion.com"}],"tags":["manufacturing-wave"],"related":[],"cancers":[],"sections":[],"technologies":["research-reactor-isotope-production","single-use-bioprocessing","radiosurgery-srs","cobalt-60-teletherapy"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hq":"Ottawa","country":"CA","companyType":"radiopharma","website":"https://www.nordion.com","stage":"public","investors":[],"funding":[]},"route":"/companies/nordion/","neighbours":{"technology":[{"id":"cobalt-60-teletherapy","kind":"technology","name":"Cobalt-60 teletherapy","route":"/technologies/cobalt-60-teletherapy/"},{"id":"research-reactor-isotope-production","kind":"technology","name":"Research reactors for medical isotopes (Mo-99, Lu-177, I-131)","route":"/technologies/research-reactor-isotope-production/"},{"id":"single-use-bioprocessing","kind":"technology","name":"Single-use bioprocessing systems","route":"/technologies/single-use-bioprocessing/"},{"id":"radiosurgery-srs","kind":"technology","name":"Stereotactic radiosurgery (Gamma Knife, CyberKnife, linac SRS)","route":"/technologies/radiosurgery-srs/"}]}}
