Picture Worth a Thousand Words - by Rolf A. F. Witzsche
ITER - The
|The reactor will
stand 100 feet tall, without substructure and containment, for a total of
120 feet (1/4 of the height of the Great Pyramid in Egypt)
The reactor will weigh 23,000 tons (three times the weight of the steel in
the Eiffel Tower) - but far too small for a practical demonstration plant
A maximum sustainable burn time of 1000 seconds is expected with continuous
refueling and fuel-cleansing - (current world
record is half a second)
Operating temperature greater than 100 million degrees, and a fast neutron velocity
of 17.6 MeV must be made tolerable in equipment design.
- materials don't yet exist that can reliably carry such loads.
- the International Fusion Material Irradiation Facility, will be
build to design and test such materials (2020-2060 timeframe)
Fusion energy expected to be generated: 500 MW thermal (ITER will not
actually utilize any, as a short-run test reactor):
- With 30% efficiency for thermal, mechanical,
and electricity conversion, the net out would equal 150 MW
Input power to cause fusion: 50MW. (Potential net output power would
be reduced thereby to 100 MW.
- Actual electricity generation is reserved for the
next step, the anticipated much larger DEMO experiment, beyond 2040, if,
- If all goes well, fusion power in the order of 2000 MW to 4000 MW might
be achievable in the 2080 timeframe,
- Commercial fusion would likely be requiring facilities 8 times larger.
