Excess heat generated by the sodium-cooled fast reactor during low compute cycles is stored in insulated tanks containing molten nitrate salt. When data center workloads spike during distributed LLM training, stored thermal energy is rapidly discharged through secondary steam generators to supply instantaneous power.
This thermal buffering architecture allows nuclear plants to run at 100% steady-state efficiency while supplying variable, ultra-high-density power demands required by modern AI supercomputers.
