plentiful & can be used to generate energy without creating
transuranic wastes. Thorium's capacity as nuclear fuel was
discovered during WW II, but ignored because it was unsuitable
for making bombs. A liquid-fluoride thorium reactor (LFTR) is
the optimal approach for harvesting energy from Thorium, and has
the potential to solve today's energy/climate crisis. LFTR is a
type of Thorium Molten Salt Reactor (Th-MSR). This video
summarizes over 6 hours worth of thorium talks given by Kirk
Sorensen and other thorium technologists.
THORIUM REMIX 2011 starts with a 5 minute TL;WL summary, to hold
you over until you find your Ritalin. YouTube Closed Captioning
is available in English, and many other languages.
A: Thorium is a naturally-occuring mineral that holds large
amounts of releasable nuclear energy, similar to uranium. This
nuclear energy can be released in a special nuclear reactor
designed to use thorium. Thorium is special because it is easier
to extract this energy completely than uranium due to some of
the chemical and nuclear properties of thorium.
Q: What is a liquid-fluoride reactor?
A: A liquid-fluoride nuclear reactor is different than
conventional nuclear reactors that use solid fuel elements. A
liquid-fluoride reactor uses a solution of several fluoride
salts, typically lithium fluoride, beryllium fluoride, and
uranium tetrafluoride, as its basic nuclear fuel. The fluoride
salts have a number of advantages over solid fuels. They are
impervious to radiation damage, they can be chemically processed
in the form that they are in, and they have a high capacity to
hold thermal energy (heat). Additional nuclear fuel can be added
or withdrawn from the salt solution during normal operation.
Q: Are the salts safe?
A: Very safe. Unlike other coolants considered for
high-performance reactors (like liquid sodium) the salts will
not react dangerously with air or water. This is because they
are already in their most stable chemical form. Their properties
do not change even under intense radiation, unlike all solid
forms of nuclear fuel.
Q: What is nuclear waste and how does a liquid-fluoride reactor
address this issue?
A: So-called "nuclear waste" or spent-nuclear fuel is produced
in conventional (solid-core) nuclear reactors because they are
unable to extract all of the nuclear energy from their fuel
before they have to shutdown. LFTR addresses this issue by using
a form of nuclear fuel (liquid-fluoride salts of thorium) that
allow complete extraction of nuclear energy from the fuel.
