Darmstadtium the JINR showed signs of Ds being produced from Pu and S. Each team proposed its own name for element 110: the American team proposed "hahnium" after Otto Hahn in an attempt to resolve the situation on element 105 (which they had long been suggesting this name for), the Russian team proposed "becquerelium" after Henri Becquerel, and the German team proposed "darmstadtium" after Darmstadt, the location of their institute. The IUPAC/IUPAP Joint Working Party (JWP) recognised the GSI team as discoverers in their 2001 report, giving them the right to suggest a name for the element. Using Mendeleev's nomenclature for
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
