Preliminary risk analysis for the installation of Small Modular Reactors in energy-deficient regions of Brazil

Abstract

This paper aims to review the feasibility of implementing PWR-type Small Modular Reactors (SMRs) in Brazil, utilizing the 5W2H methodology for a preliminary risk assessment. SMRs are seen as a promising solution to meet the country's growing electricity demand and diversify its energy matrix, particularly in underserved regions. With projections extending to 2050, the construction of these reactors offers significant benefits, leveraging modularization techniques to accelerate deployment and reduce costs. Selecting optimal locations—such as areas near the São Francisco River—and fostering collaboration between government and private entities are crucial for the project's success. While this analysis is preliminary, the findings suggest that SMR adoption in Brazil presents a strategic opportunity to enhance energy sustainability, reduce greenhouse gas emissions, and ensure a secure and efficient energy future for the country's most disadvantaged regions.
