Are size and efficiency the most pressing issues to solve in nuclear power? You'd think the greatest problem facing a potential buyer is getting planning permission and insurance. Who wants a nuclear reactor down the road, even if it's a scaled-up TRIGA design? From what thin details are there in the Techcrunch writeup ("spent fuel from it can be reused in another reactor with some processing") it could almost be a pulse reactor, the design is well-understood. Another worry is getting rid of the used fuel rods. With all the 70-odd TRIGAs operating around the world, the United States will take them back, but who can tell with a startup?
