Yeah I read that, but it's not going to be good for that. For one thing that isn't going to work in a nuclear reactor core because the neutron background is orders of magnitude higher than any neutron generator could hope to produce. For the other uses they mentioned... I mean like I said there's no reason it wouldn't work (over short ranges) but there are simpler solutions that don't involve [very dangerous] neutron radiation. Plus a neutron generator requires a decent bit of power to run (they're basically a compact particle accelerator) so you're back to needing a vessel penetration. And the idea that such a device would be useful for emergency rescue operations is frankly silly.
