The Dual Fluid Reactor

Developed at the Institute for Solid-State Nuclear Physics, Berlin, Germany

  • Uses existing and proven technologies in a novel way.

  • Simple Design - cheaper to build and to operate than current reactors.
 

 

 

The Dual Fluid Reactor

Developed at the Institute for Solid-State Nuclear Physics, Berlin, Germany

  • Based on Generation IV reactor concepts.
  • Uses two separate fluids instead of one.
  • Molten Salt of natural uranium or thorium as fuel, and liquid lead for cooling.
  • The waste of current nuclear reactors can also be used as fuel for DFR.
 
 
  • Transmutes waste from today's interim storage facilities
  • Remnants have to be stored only for 300 years
  • No final geological storage needed
 

 

 
  • No enrichment facilities needed
  • No external reprocessing plants needed
  • Mining and fuel fabrication reduced by a factor of 200
 

 

 
  • Immediate power regulation → No excursion possible
  • Passive safety systems - no overpressure
  • Inherently safe
 

 

 

For full electricity supply of 10 billion people, the DFR...

  • …extends the Uranium scope to 10 million years
  • …extends the Thorium scope to 500 million years

(Accessible space resources not even included)

 

 

 

Electricity production with high efficiency

  • Overnight capital costs: 1.2 US$ per Watt installed power
  • Electricity production costs below 1 US-cent per kWh
 

 

 

Automotive fuel production with high efficiency

  • Hydrazine: 40 US-cent per liter gasoline equivalent
  • Ammonia: 20 US-cent per liter gasoline equivalent

(Completely CO2 free)
