Potential hybrid systems could utilize proven LWR technology or proposed advanced reactor technologies that would operate at higher temperature and, hence, provide higher temperature heat for non-electrical applications. SMRs offer unique opportunities for hybrid system applications due to their small size, modular implementation, operational flexibility, and investment flexibility. Potential SMR-hybrid implementations are explored below, with a focus on system siting and nuclear-renewable integration. Detailed discussion of potential non-electrical applications that could be integrated in such a system is provided in Section 13.5.
