Two Furnaces for Testing a Fusion Fire
ITER (International Thermonuclear Experimental
Reactor) (see display in Lobby) Six party
international partnership (JA,EU,RF,US,CN,ROK)
To be built in Japan or France (Cost gt 5B)
Under negotiation ( decision expected by July
2004) FIRE (Fusion Ignition Research
Experiment) Lowest cost approach for studying
science of fusion fire International
Collaboration lead by the US To be built in
the US (Cost 1B) Under design as back up,
put forward if no ITER decision ITER and FIRE
are each attractive options for the study of
burning plasma science. Fusion Energy Sciences
Advisory Committee 2003

FIRE Would Test Confinement Similar to Power Plant

• Tokamaks have established a solid basis for
  scaling confine-ment of the diverted H-Mode.
• BtE is the dimensionless metric for confinement
  time projection
• ntET is the dimensional metric for fusion
  - ntET
  bB2tE bB . BtE
• FIRE only needs to increase confinement BtE by
  2.5 !!!
• ARIES-RS Power Plants require BtE slightly larger
  than FIRE due high b and B.

Characteristics of the FIRE Furnace

• 40 scale model of ARIES-RS plasma
• Strong shaping kx 2, dx 0.7, DN
• All metal plasma facing components
• Actively cooled tungsten divertor
• Be tile FW, cooled between shots
• T required/pulse TFTR 0.3g-T
• LN cooled BeCu/OFHC toroidal B coil
• no inboard nt shield, allows small size
• 3,000 pulses _at_ full field
• 30,000 pulses _at_ 2/3 field
• 1 shot/hr _at_10T/20s/150 MW
• Site needs comparable to previous
• DT tokamaks (TFTR/JET).

Computer Simulation of Fusion Fire is Needed
Fusion fires are complex, non-linear and
strongly-coupled systems. highly self driven
(83 self-heated, 90 self-driven current)
plasmas are needed for economic power plant
scenarios. Does a fusion fire naturally
evolve to a self-driven state?
A capability to simulation fusion fire would be
of great benefit to Understand fusion fire
phenomena based on existing expts Refine
the physics and engineering design for fusion
fire expts Provide real time control
algorithm for self-driven fusion fire, and to
optimize experimental operation Analyze the
fusion fire experimental results and transfer
knowledge.

Concluding Remarks
Magnetic Fusion has made steady progress during
the past decades and has achieved fusion
fuel temperatures of 500 million degrees C
(TFTR) fusion power production of 10 million
watts (TFTR) fuel density x confinement 50
of fusion fire (TFTR) first fusion fuel
heating by fusion fire (TFTR) More important
than ever to find out if fusion can be an energy
source for the world. Magnetic Fusion is now
poised to take the crucial step of building
and testing a fusion fire in the Laboratory
two attractive options (ITER and FIRE) are
available decisions are expected within
months Thanks for your interest. More info at
