Thanks for the answers. A higher-power PULSTAR derivative still needs NRC design approval, right? Or will the reactors be built somewhere that has a simpler approval process for new designs? I've seen people say that Canada is more favorable to novel reactors though I haven't looked into the details.

The NorthStar chemistry advantage looks (IMO) to be the absence of fission products, which are diverse in chemical behavior and radiotoxicity. I have no idea if that can sufficiently offset the complications that come from lower specific activity in the product.

Good luck with your endeavor! I love to see startups that deliver physical products and not just software, especially a product as important as this one.
