Indeed. I get the impression that the 3He will come from the D-D reaction, which itself produces a neutron....unless they use a well shielded D-D fueled reactor to produce the 3He which is then separated out and used in other less shielded reactors in a D-3He reaction. However even if you use a fuel mix that is very heavy on 3He, you will still get some D-D reactions. (And not to forget that inevitable D-T reactions produce a very fast neutron!)
