Dual Fluid demonstrates new fission principle on model

By 21. July 2022No Comments

The Canadian-German nuclear technology company Dual Fluid has produced a simplified polymer model of its reactor core. It is intended to demonstrate Dual Fluid’s fundamentally new nuclear fission process, based on liquid fuel and lead cooling, as realistically as possible using substitute products. The model can already provide indications of flow behavior and confirm finished calculations in reality.

The new nuclear fission by Canadian-German company Dual Fluid utilizes two liquids in the reactor core instead of fuel rods: metallic nuclear fuel, plus lead to remove the heat. The goal is a more efficient and less expensive type of nuclear power that is inherently safe. The new operating principle is now being demonstrated on two different models, one after the other. The first of these, a transparent polymer model, is operated with non-nuclear substitutes. It can provide initial indications of how the fabrication and joining processes must be carried out in the eventual power reactor. In addition, the model allows existing fluid dynamic calculations to be compared with reality. This is possible because the substitute fluid used is water. At room temperature, water exhibits similar thermohydraulic properties to the liquid metals proposed in the reactor at 1000°C.

The polymer model will be on display in the Berlin Institute for Solid State Nuclear Physics. It is identical in form, function and size to a planned ceramic model that will be operated with uranium and lead.

About Dual Fluid

Dual Fluid is creating an entirely new type of nuclear reactor that

  • provides emission-free electricity and hydrogen,
  • significantly reduces today’s energy costs,
  • burns nuclear waste, and is inherently safe.

Dual Fluid differs from other new nuclear concepts by its high efficiency: the nuclear fuel is utilized up to a hundred times better than in today’s light water reactors. The operating temperature of 1000° C enables new heat applications.

The Dual Fluid operating principle, based on different fluids for fuel and cooling, is described in scientific publications. There is worldwide patent protection, including in the USA, Canada, the EU, and Japan.
Dual Fluid Energy Inc. was incorporated as a public company in Vancouver, Canada, in January 2021 to bring the Dual Fluid technology to serial production status. The prototype of a Dual Fluid reactor is to be launched within this decade.
