Modelling of Heat, Energy Management and Conversion for Advanced Nuclear Technologies (MoHECANTe)
The world’s current electricity demand stands at over 23 Thousand TeraWatt hours (TWh), which is predicted to increase to 40 Thousand TWh by 2050. This is based on trajectories that consider increased demand due to digitisation, electrification of transport and industry, and production of hydrogen (IEA, 2019).
Current energy mix is dominated by fossil fuels but this demand for fossil fuels is diminishing due to depleting reserves but more importantly climate emergency. Future energy sources will be dominated by low-carbon and renewable energy technologies to meet UN Sustainability Development Goal (SDG). Advanced Nuclear Technologies (ANT) offer the prospect of electricity generation and decarbonisation of a wide range of processes as part of co-generation. However, there is little understanding of the dependencies and requirements of the heat exchanger and the heat management system, due to the challenges of modelling the various technologies, in combination with the reactor. This makes decision-making and investment routes for development challenging. This creates the need for the application of high-fidelity modelling of the technologies to understand dependencies and requirements for technology development and maturity
EGB Engineering MoHECANTe project involved modelling and simulation of Advanced Nuclear Technologies, specifically the reactor, heat exchanger and the energy conversion systems to understand and quantify the requirements that they place on heat transfer and the management systems for electricity and process heat.
