Why Nuclear Shipping Is Inherently Niche

Why have we built nuclear ships before, proven they can operate, and still not made them commonplace? Nick Touran breaks down the history of maritime nuclear power, from the Nuclear Ship Savannah and Otto Hahn to Japan’s Mutsu and Russia’s Sevmorput, then pivots to floating nuclear power concepts such as the MH 1A Sturgis and the Offshore Power Systems program. We explore what worked, what failed, and what keeps blocking adoption, including port access rules, indemnity and international agreements, staffing costs, containerization economics, shielding and public reaction, and the unique operational demands of running reactors at sea.
