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 panel session will highlight current and emergent issues in consensus standards, with a focus on industry needs for standards actions. The topics will also include: moving from risk informed to performance based standards; harmonization among ANS standards and between ANS standards and standards from other SDOs; digital twins as an adjunct to licensing by test; potential for standards action for System-Theoretic Process Analysis; perspectives by several ANS Consensus Committees; and may include perspectives from ASME, EPRI, IEEE, INPO, NEI, ISO and regulators. The Risk-Informed, Performance-Based Principles and Policy Committee (RP3C) has participated in organizing this panel.
