IAEA conducts safety review of South Africa’s SAFARI-1
A team of nuclear safety experts with the International Atomic Energy Agency completed a five-day safety review of the SAFARI-1 reactor in Pelindaba, South Africa, focusing on aging management and continued safe operation of the 61-year-old 20-MW research reactor.
The IAEA team found that the SAFARI-1’s management and technical staff had a strong commitment to and involvement with the assessment but recommended that formal programs be established to address the aging reactor’s equipment.
