Nuclear power is up-to now mainly restricted to the generation of electricity by LWR. In the future, nuclear energy can also be used for Cogeneration of Heat and Power (CHP). Through utilization of the heat, the overall fuel efficiency of CHP plants can reach around 70- 80% if the power size is adapted to the local heat and electricity demand. The industrial process heat market today is at least of the same size as the electricity market. Worldwide, this market is strongly growing and almost entirely based on combustion of fossil fuels which are increasingly scarce and suspected to induce climate change, causing the risk of unstable supply, unwanted cost fluctuations and political dependencies. Through substitution of fossil energy imports, nuclear CHP can provide a significant contribution towards increased security of energy supply in a CO2-lean Europe.

Advanced reactor systems, such as High-Temperature Reactors (HTR) are required to achieve steam conditions (>600°C), which can compet e with modern conventional power plants. Such plants are used in many industrial CHP applications by burning fossil fuels and producing hot flue gas for energy conversion. In analogy, nuclear heat can be used to operate industrial processes. However, a convincing demonstration of nuclear CHP will be necessary to open the heat market for nuclear energy for further substitution of imported fossil energy carriers and reduction of greenhouse gas emissions.

This project focuses on generic and cross-cutting V/HTR-related R&D issues and supports European contributions towards international demonstration of HTR and VHTR technology.
