It converted its molybdenum production to low-enriched uranium targets ahead of other producers. Regulator-ordered shutdowns of its processing facility in 2017 and 2018 removed a large share of world molybdenum-99 supply for months and showed how few processors there are.","asOf":"2026-09-17","links":[{"label":"Official website","url":"https://www.ntp.co.za"}],"tags":["manufacturing-wave"],"related":[],"cancers":[],"sections":[],"technologies":["research-reactor-isotope-production","therapy-isotope-supply-chain"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":[],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hq":"Pelindaba, near Pretoria","country":"ZA","companyType":"radiopharma","website":"https://www.ntp.co.za","stage":"private-large","investors":[],"funding":[]},"route":"/companies/ntp-radioisotopes/","neighbours":{"technology":[{"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":"therapy-isotope-supply-chain","kind":"technology","name":"Therapeutic isotope supply chain (Mo-99, Lu-177, Ac-225)","route":"/technologies/therapy-isotope-supply-chain/"}]}}
