Control Analysis of ARC-100 Reactor with sCO2 Cycle

ARC-100 plant control during load following has been investigated using coupled SAS4A/SASSYS-1 and PDC codes. ARC-100 is a 286 MWth/100 MWe sodium-cooled fast reactor featuring sCO2 cycle for energy conversion. A linear reduction in grid demand from 100% to 0% at 5%/min rate was simulated and the required plant control action was calculated to match that grid demand. The paper presents the results of the ARC-100 plant load following with inventory control on the sCO2 cycle and several reactor control options.
