I can no longer locate the source posting, but I distinctly recall something (I think from Eric) indicating that the B10 was external, not dissolved. Something like 1″ or so thickness.

That was my understanding- a metal or plastic water tank containing a 1m (distilled?)water shield, covered by 10cm of boron (type unspecified), covered by 2cm of lead or boronated polyethylene. We discussed this with Eric and Rematog around March of ’09 iirc. Searching the site for boronated polyethylene may bring up the thread.
