I suppose the 764 keV could be kinetic: n + 3He → 3H + 1H + 0.764 MeV I expect the concentration of ³He in your blanket would be extremely low, relative to

I suppose the 764 keV could be kinetic: n + 3He → 3H + 1H + 0.764 MeV I expect the concentration of ³He in your blanket would be extremely low, relative to the Li, so an unlikely target. Really, if it takes neutrons, it is not a problem.
