One of the main problems with small modular reactors is that they generate reactive waste that is easily ignited. Canada has a long‑term project to create a deep geological storage site for waste, but we don't even know if we're going to be able to put the waste from small modular reactors there because it could ignite and set the deep landfill on fire.
No waste management strategy for small modular reactors emerged from the consultation conducted by the Nuclear Waste Management Organization, or NWMO. It's not possible, because the waste from small modular reactors is not well characterized. We don't know what it's going to be. We know that it will have a shorter lifespan and a lower intensity, but that it will be more complex in terms of intermediate and low‑level waste. So it's totally unknown, and we don't know what to do with it. There's no strategy.
