Disclaimer: I know nearly nothing about this stuff. Almost none of the problems listed there seem to be deal breakers. Most of them seem to be a matter of small improvements that probably aren't the primary focus of research right now. For example I'd imagine researchers have a fairly steady supply of tritium, they don't need to focus fairly hard on recovering it all, just enough to save on costs since it's pretty expensive. Why bother trying to recover 100% of tritium for a reaction that you can't even get energy positive yet? Trying to make it more efficient when you can't even make it work seems to be putting the cart before the horse. And that seems to be the case with the fuel, too (at least how described in the article). Once we get the process working with the easy fuels it seems that the next target for research would be using fuels that might be better but harder to work with. >Corrosion in the heat exchange system, or a breach in the reactor vacuum ducts could result in the release of radioactive tritium into the atmosphere or local water resources. Tritium exchanges with hydrogen to produce tritiated water, which is biologically hazardous. > Most fission reactors contain trivial amounts of tritium (less than 1 gram) compared with the kilograms in putative fusion reactors. But the release of even tiny amounts of radioactive tritium from fission reactors into groundwater causes public consternation. He seems to negate his own point by saying that the tritium output is less than a thousandth of what it is in fission. It might not be perfect but that sure sounds like an improvement to me. Even better once they start recovering larger amounts of it (he said himself that they need to recover at least 99% of it). Also, from my (limited) knowledge of tritium it isn't that dangerous. It is in watches, weapon sights, emergency signs, and many other glow in the dark things. I've researched it before due to having several tritium containing products and it seems that in small amounts it simply vents into the atmosphere and becomes a non issue. Anyway please correct me if I'm wrong on anything.
