Otto Hahn
Otto Hahn is a nuclear-powered cargo ship operated by West Germany, powered by Integral PWR of about 36 MWt. Retired.
Sailed 650,000 nautical miles on 126 voyages over ten years without a technical problem, and was converted to diesel in 1982 purely on cost. The most successful civil nuclear ship by operating record, and still not economic.
