Anything at 300 C or below can be provided from renewable sources using industrial heat pumps. Heat is very storable, compared to electrical energy, so if the end user needs heat they could make the heat when renewable energy is cheap and store it, potentially for very long periods. Some district heating systems involve seasonal storage, essentially artificially charged geothermal. Nuclear thermal would be competing with otherwise curtailed renewable energy, which can be very cheap on the margin.
