10 Where to put a new reactor? Site Screening Size of the site location Terrain of the proposed site Through a multi-attribute analysis, location and construction less favourable site locations were area screened out and then there were three... Ease of integration into the existing facilities and infrastructure Proximity to hazardous facilities Any other known disqualifier Continues 10

15 Safety Assessment and Licensing 15

16 Safety Assessment Radiological Impact on the public from all the facilities at Pelindaba, including a new reactor. Regulations on a risk assessment for a site license 16

17 Engaging with the National Nuclear Regulator Early stages of engaging with the regulator Staged approach to licensing: siting, construction and operation. So far, we ve had positive interactions. The siting of the Dedicated Isotope Production Reactor is progressing well and we have confidence that the Site Safety Report will be well received by the South African National Nuclear Regulator. 17
