Small Modular Reactors in Industrial and District Heating Combined with Thermal Energy Storage System

Popis výsledku v původním jazyce

With increasing number of small modular reactors (SMR) aimed for industrial and district heating, as DHR400 or TEPLATOR (R), a thermal energy storage (TES) seems to be an interesting system feature. Nuclear reactors are generally not designed for rapid power changes, as they are usually connected with unwanted phenomena as xenon poisoning or increased mechanical stress to fuel cladding caused by pellet - cladding interaction. Nuclear reactors are generally better to operate at nominal power, what is more or less easy to do with base load electricity production for large electric grid but may cause several issues in generally smaller district heating grids with more variable consumption profile. On the other side are an industrial (stable with better prediction) consumption or district household heating with variable and less predictable consumption profile. Industrial and district heating systems has different requirements for dynamic response varying from immediate, short term full power delivery (e.g. for finishing already started batch of product before forced manufacturing line cool-down) to long term delivery with more relaxed parameters (e.g. for residual area district heating). In this study we would like to introduce a concept of a thermal energy storage as a dynamic system connecting SMR and district heating, considering different requirements on both sides with different dynamic system response.
