Fusion is different than Fission.

So it is.

Here's a basic fusion reaction, in which deuterium fuses with tritium to produce helium and a neutron.

If enough of the above events to produce meaningful power were taking place, there should have been lots of neutrons zapping around.

They don't claim to be fusing deuterium with tritium, though. They claim to be fusing protium with something else (protium? nickel?). So they wouldn't necessarily be making any neutrons.

The sun does a whole lot of fusion, but produces very few neutrons, which is one reason you and I are alive to talk about it. It's mostly converting protium to helium 4, without making free neutrons.
