In the FAQ “Focus Fusion vs. Nuclear Reactors” it is admitted that there is (at least) one secondary reaction that can create neutrons. Some of those neutrons will strike reactor internals and make them radioactive. It is these activated materials that are of concern.

Secondary reactions can be minimized, but not totally eliminated, by adjustment of the operation cycle. Activation products can be minimized, but not totally eliminated, by proper selection of construction materials.

Only operational experience will tell how much radioactivity is generated and how concerned we need to be.

I hope that my concerns are unfounded. I hope that Focus Fusion will find wide-spread application and power our world into a bright future.
