The Proponent proposes utilizing a 'graded approach' where detailed post-closure design information is 'refined at later licensing stages' under the CNSC, rather than during the current Impact Assessment. For the residents of Melgund (Dyment/Borups Corners), who will live next to this waste permanently, deferring detailed safety analysis is unacceptable. A 'conceptual' analysis is insufficient to evaluate the long-term psychological and socio-economic impacts of potential containment failure. We must require the Proponent to model worst-case scenarios now, rather than waiting for future technical licensing phases. This ensures the community can provide informed consent based on the maximum possible risk, rather than a theoretical concept that will change after construction begins.
