El Salvador: Looking to nuclear
In 2022, El Salvador’s leadership decided to expand its modest, mostly hydro- and geothermal-based electricity system, which is supported by expensive imported natural gas and diesel generation. They chose to use advanced nuclear reactors, preferably fueled by thorium-based fuels, to power their civilian efforts. The choice of thorium was made to inform the world that the reactor program was for civilian purposes only, and so they chose a fuel that was plentiful, easy to source and work with, and not a proliferation risk.

This paper builds on previous work that characterized the nature of the nuclear power plant (NPP)–electric Grid system, the concept of Grid resilience, and the potential of current U.S. NPPs to enhance the U.S. Grid, integrated Critical Infrastructure, and societal resilience. The concept of a resilient nuclear power plant (rNPP) is defined. Two rNPP Key Attributes and Six rNPP Functional Requirements are presented. A preliminary discussion of some rNPP design features that could enable an NPP to achieve the Six rNPP Functional Requirements is presented, along with a preliminary discussion of some rNPP regulatory, siting, and economic considerations. Taken as a package, the Six rNPP Functional Requirements define an NPP performance envelope that extends the societal value proposition of nuclear energy well beyond that of traditional baseload electricity generation. The paper lays the foundation for exploration of high-value rNPP applications and for future rNPP conceptual design studies.
