Some experts don't think that fusion reactors will live up to their promise:
"“Long touted as an inexhaustible energy
source for the next century, fusion
as it is now being developed will
almost certainly be too expensive and
unreliable for commercial use.”
The dominating goal of the fusion program is
to produce a reactor fueled by deuterium and
tritium, isotopes of hydrogen containing one
and two extra neutrons. This choice of fuel
greatly eases the problem of achieving an
energy-producing fusion reaction, but the
choice also has features that make it far more
diScult to turn that energy source into a useful
power plant. The most serious diSculty concerns
the very high energy neutrons released in
the deuterium-tritium (D-T) reaction. These
uncharged nuclear particles damage the reactor
structure and make it radioactive. A chain of
undesirable eFects ensures that any reactor
employing D-T fusion will be a large, complex,
expensive, and unreliable source of power.
That is hardly preferable to present-day fission
reactors, much less the improved fission reactors
that are almost sure to come."

Don't count on it. You got the the European Union through the legally distinct organisation EURATOM, India, Japan, People's Republic of China, Russia, South Korea, and the United States of America (USA) working on ITER reactor, EU has another product and US has their own. US has DIII-D · TFTR · NSTX · NCSX · UCLA ET · Alcator C-Mod · LDX · MSTNIF · OMEGA · Nova · Nike · Shiva · Argus · Cyclops · Janus · Long path · Z machine · PACER
