I don't know - it's his figure, not mine.
Also, the deuterium fraction in seawater is already around 1/6000, resulting in a D-D fusion rate down seven and a half orders of magnitude from pure deuterium even if you do nothing at all to get rid of it. Doesn't sound like much of an issue even with moderate isotopic separation...
I wondered if there was an expotential element to the D-D rate vs relative population portion- looks like there is. Also, any deuterium present would possibly react with the much more common protons to produce He3 and a gamma ray. But the rate may be so low that it is no more significant than the extreamly rare D-D reactions. I briefly looked but I found no mention of possible D- B11 reactions.
