NUCLEAR POWER

r Götz Ruprecht is CEO of Dual Fluid. Here, we get his insights on the advantages of his reactor technology and how he thinks this technology will evolve in the coming years.
YOUR COMPANY SLOGAN IS “WE ARE REINVENTING NUCLEAR” – WHY AND WHAT FOR? “We are reinventing nuclear power because it off ers tremendous opportunities. Current nuclear technology does not properly exploit the potential of uranium as a fuel: today’s reactors convert only 3-5% of the fuel into electricity, the rest has to be disposed of. We are developing a completely new type of nuclear fi ssion based on liquid metal fuel and liquid lead coolant. T is will allow us, for the fi rst time, to fully exploit the power of the ultra-dense uranium fuel and exponentially increase the performance of nuclear power. T e very high operating temperatures of 1,000°C – an absolutely unique feature – allow a wide range of interesting applications. For example, the production of hydrogen from water through high-temperature process chemistry – an attractive prospect for meeting the growing demand for hydrogen in a cost-eff ective, environmentally friendly way.”
WHAT IS THE ADVANTAGE OF HIGH-TEMPERATURE PROCESS CHEMISTRY? “T e advantage is clearly price: the higher the temperature, the more effi cient and cheaper the process. By way of comparison, emission-free hydrogen from wind energy costs 6-8 US cents per megajoule to produce today. Conventional hydrogen from methane steam reforming is much cheaper at 1.3 to 1.8 US cents. T is is about the price at which emission-free hydrogen could be produced using the smallest Dual Fluid reactor of 300MW electrical power. Larger models would allow further

FUTURE FOCUS
Lisa Rass interviews Götz Ruprecht to discover his vision for the future of nuclear power
signifi cant cost reductions. Another interesting application is the production of emission-free synthetic fuels that can power common combustion engines. In this way, the uncomplicated decarbonisation of the transport sector would be possible.
WHICH FUEL DOES THE REACTOR USE? ‘It is a fast reactor that can use any fi ssionable material as fuel – uranium, thorium or reprocessed nuclear waste. T is makes our technology particularly interesting for countries that already have an inventory of spent fuel. In fact, what we call “nuclear waste” is a valuable resource that, with the right technology, can be used very profi tably.”
WHERE ARE YOU IN THE DEVELOPMENT OF YOUR REACTOR? “After a decade of detailed preparation and improving the concept in theory, we are now going to build our fi rst
reactor – a demonstration reactor as proof of concept. It will demonstrate the fundamentally new operating principle for the fi rst time in reality by the middle of the decade. A partnership with Rwanda, which is providing the site, off ers us ideal conditions for this. We are just raising funds for this important step. T e prototype of the fi rst 300MW power reactor should be up and running by the end of the decade, with series production starting a few years later.”
WHICH INVESTORS ARE YOU ADDRESSING? “We are addressing major investors interested in pragmatic and viable energy solutions. Our product off ers trailblazing advantages to a global market. We are off ering the chance to grow with us and serve this market.”
