Core Model Proposal 407: Add Small Modular Reactors
Abstract
The goal of this core model proposal is to add small modular reactors (SMRs) as a new nuclear technology in the Global Change Analysis Model (GCAM). We introduced new data processing in gcamdata that incorporates global assumptions about SMRs from the Annual Technology Baseline (ATB) across all GCAM regions. We replaced the "Gen III" reactor with a “large reactor” and added “SMR” as a new technology in GCAM.Published: November 10, 2026
