Nuclear process heat applications for the modular HTR

Abstract The advantages of the modular HTR as heat source for process heat are described below. Subsequently various possibilities for heat removal are presented, e.g. via a steam reformer, an He/He intermediate heat exchanger and a steam generator. The influence exerted by the process plant on pressures and temperatures in the reactor plant is explained. This is followed by a description of plants for the production of SNG (substitute natural gas) and methanol using both the hydro- and the steam gasification of coal, whereby synthesis gas is produced in the intermediate step. The production of synthesis gas from natural gas, the production of hydrogen and the application of steam generation for the production of electrical power and/or process steam are briefly considered. In conclusion, some remarks are made on the commercial efficiency and the commercial utilization of modular HTR plants.
