The thesis investigates whether integrating nuclear energy directly with carbon capture and storage systems is feasible and environmentally and economically superior to fossil fuel-powered alternatives. It assesses two pathways, nuclear-powered point source capture and small modular reactor cluster paired with direct air capture, through techno-economic and lifecycle environmental frameworks; identifies six regulatory gaps; and proposes a blended financial and environmental policy framework to address them. Its central conclusion is that nuclear-CCUS integration is the only current available pathway capable of delivering genuine zero-carbon industrial decarbonisation and land-efficient atmospheric CO₂ removal simultaneously, making it an essential component of any credible net-zero strategy
