    >Rather than reviving the large reactors of the past, the government is focusing on small modular reactors, or SMRs, and other advanced technologies that supporters say could be safer, more flexible and quicker to build.

    >The legislation does not authorize the construction of any reactors. Instead, it creates the regulatory foundation needed before future projects can be proposed, assessed and approved.

    Giant step for SMRs. I'm hopefull for greater NATO collaboration regarding energy security if SMRs prove commercially viable.

      I don't understand why people are so bullish about SMRs. 25 years ago we were trying to increase reactor size and testing breeders, no we want smaller reactors, for what reason?

        I always thought it was about commoditization: sure a SMR might cost 10x more per watt in theory but if you can reliably roll them off the production line without having to redesign each iteration and without the cost overrunning by 10x, it pays for itself.

          Still doesn't make sense. We could have standardized the old reactors too.

          Radioactive material and a bit of water.. there's no reason to design those things a hundred times. France actually did that.

          France is still shutting down its plants because the rivers are too warm in the summer. As for floating SMBs in the harbour, I don't think climate change will be kind to this idea.

            That's because French nuclear power plants are designed to be directly cooled by river water instead of using cooling towers.

            The biggest nuclear power plant in the US (Palo Verde Generating Station in Arizona) is cooled by evaporating the treated wastewater, in the desert.

              All these extra methods of preserving water adds cost, to a technology where paid off plants are struggling. Let alone ruinously expensive new builds.
