Abstract

This article examines Small Modular Reactors (SMR) and Micro Modular Reactors (MMR) technologies, which are gaining increasing importance in the global energy transition alongside renewable energy sources on Turkey's path to clean energy independence, through a comparative analysis of their environmental impacts and other resources. The study investigates the definition and classification of these reactors, their current global development status, environmental advantages such as low carbon footprint, and various environmental risks, primarily nuclear waste management. In addition, SMR/MMR technologies are evaluated comparatively with fossil fuels and renewable energy sources within the framework of life cycle analysis (LCA). The findings reveal that SMR and MMR have a critical role as a base load in line with net-zero targets, but emphasize that realizing this potential depends on solving structural problems such as nuclear waste, water usage, and proliferation risk.
