Are there any published works showing nuclear phenomena such as
excess heat, correlated with deuterium percentage? I'm starting with
99.9% D2O (atom percent D). What would be the difference I should
expect with 98% D2O, which is substantially cheaper? I've seen
rumors that ordinary water "poisons" the reaction. If so, at what level?
With solid Pd in the conventional FP configuration, even a little
light water poisons the reaction. I think even 1 or 2% but I do not
recall. Storms says that with electrolysis the Pd preferentially
absorbs the H atoms so the concentration of H in the lattice is soon
higher than in the starting liquid.
Heavy water is hygroscopic. (Try saying that word three times in a
row!) Meaning it readily absorbs ordinary water from the air. You
might say it wants to get back to its natural ratio of 1:6,700 atoms.
Anyway, people sometimes leave bottles of heavy water open to the air
during experiments, and this ruins them by reducing purity. To
prevent this with open-cell experiments, Bockris recommended putting
the heavy water reservoir in a plastic IV bag with an IV tube leading
down to the cell, with one of those itty-bitty stopcocks at the top
of the cell. You exclude air the whole way. You dump and throw away
the first small amount of little heavy water that comes through the
empty tube. Bockris also thought that CO2 poisons the reaction. Or
any kind of carbon.
Storms also used an IV bag in some tritium studies, I assume for the
same reason:

Those bags are clean and airtight and made to high standards, since
air or contamination might harm the patient.
