Otto Hahn in an obituary: Hahn's death did not stop his public acclamation. Proposals were made at different times, first in 1971 by American chemists, that the newly synthesized element no. 105 should be named hahnium in Hahn's honor; in 1997 the IUPAC (International Union of Pure and Applied Chemistry) named it dubnium, after the Russian research center in Dubna (see element naming controversy). Although element 108 was given the name hassium (after Hesse) by its officially recognized German discoverers in 1992, a 1994 IUPAC committee recommended that it be named hahnium (Hn), in spite of the long-standing convention to give the
Otto Hahn (ship) She had covered 250,000 nautical miles (463,000 km) on 22 kilograms of uranium. In 1979 "Otto Hahn" was deactivated. Her nuclear reactor and propulsion plant were removed and replaced by a conventional Diesel engine room. In nine years, she had travelled 650,000 nautical miles (1,200,000 km) on nuclear power, visiting 33 ports in 22 countries. The containment vessel of the nuclear reactor is stored at the Helmholtz-Zentrum Geesthacht – Zentrum für Material- und Küstenforschung GmbH and the nuclear fuel in the United States. In 1983, "Otto Hahn" was recommissioned as the container ship "Trophy" and leased into commercial service. On
