Stripping in D2O?
Fred,
Free neutrons are - pound for pound, among the most
valuable commodities on earth (even if you can only weigh them theoretically).
Far more valuable than diamonds or gemstones. So it is a bit of a surprise
that any and all of these ideas on deuterium stripping are not being pursued
more intently. Even the Fusor is ignored officially, and LENR advocates are
generally ignoring the latest Mizuno work.
However, I think IF one can easily strip a very
small percentage of metastable deuterons, then the most efficient use of the
resultant free neutrons is going to be as "makeup" neutrons - to be employed
in small, mass-produced rail-mounted subcritical reactors of about 20-50 MW
each, fueled by natural uranium - but not exactly like the CANDU or newer
ACR700 - which design is a pressurized plumbing nightmare and does not
get the full benefit of an extremely "cheap" source of neutrons - although the
worst kept secret in nuclear engineering is that there is a huge anomaly in
how many free neutrons one gets from a deuterium moderator.
A total redesign, with an eye towards smaller,
cheaper, safer, and no steam (direct electrical conversion) could have be
done here in the USA anytime in the past two decades, were it not for the
interests of the "club" dominated by the General Electric Company, which is
second to only Halliburton-Big-Oil in political clout (and has been for 60
years previously). We have billions of dollars of sunk cost in an
infrastructure of antiquated dangerous technology and subsidized
enriched-fuel, dominated by GE, its minions at DoE and DoD and the
other club-boys - and no willingness to change things. It is a source of
amazement that some European country has not stepped-in with a better answer,
but the unnecessary baggage and political problems for nuclear are even
more severe there.

A back-of-the-envelope calculation to see how many neutrons and 2.0 MeV
Gammas
a steam power plant could produce based on one deuteron per 7,000 H2O
molecules at a heat rate
of 10,000 BTU/KWe (About 8.33 lbs H2O/KWe).
At 1/7000 (~1.0e19 deuterons/gram) = 1e19*454*8.33 = 3.78e22 deuterons
or possible stripped neutrons/KWe to
recombine with an H atom to form a new deuteron releasing a 2.0 MeV
gamma with
a total energy of ~11 Megawatts worth of gammas.
OTOH. With one per million low energy "metastable" deuterons ~ 3.78e16
neutrons/KWe
and 11 watts worth of gammas. Still a lot in a 500 Megawatt
(500,000 KW) power plant
