This dissertation evaluates the viability of nuclear power for commercial shipping through a multidimensional assessment covering environmental, economic, safety, and social aspects. The research compares nuclear-powered vessels with conventional and alternative-fuel ships across their full life cycles. Findings indicate that while nuclear propulsion entails a high initial investment, its long-term stability, independence from fuel prices, and immunity to carbon costs make it economically sustainable beyond 2040. Environmentally, nuclear energy offers near-zero operational emissions, though challenges remain in waste management and public acceptance. Technological advances, such as Small and Molten Salt Reactors, have enhanced safety and efficiency, yet regulatory and societal readiness still lag behind. Overall, nuclear propulsion emerges as a high-risk but high-reward pathway toward maritime decarbonization, requiring international cooperation, coherent policy frameworks, and renewed public trust.
