Abstract

Nuclear power plants (NPPs) generally operate in a base-load due to their high capital costs, and relatively small fuel costs. As the share of intermittent renewable power in the energy mix increases for some countries, the capability of power maneuvering (load-following) of the NPPs is becoming more important in order to adapt the electrical supply to daily or seasonal variations of the power demand. In order to keep nuclear power competitive especially in the deregulated markets, it is important for the NPPs to develop better load following capabilities. It is also desirable to improve their thermal efficiencies, which would reduce their capital investments. This paper presents a hybrid small modular boiling water reactor (SMBWR) combined with gas fired superheater concept to enhance the competitiveness of nuclear power. In this hybrid system configuration, nuclear heat is used to generate saturated steam while fossil heat is used to superheat the steam. The load-following operation could be done by varying the fossil heat supplied to the superheater while ensuring that the nuclear reactor operates at its full power at all times. This paper presents simple economic analysis of the hybrid concept as well as thermodynamic cycle analysis of DMS, an SMBWR developed by Hitachi-GE, combined with gas fired superheater.
