Konvoi was a more or less standardized pressurized water reactor design from German Kraftwerk Union AG (KWU) (later, Siemens) with rating 1300–1400 MW. Internally, it referred as Baulinie 80 (Construction Line 80). It was developed from Pre-Konvoi reactor design. Konvoi installed at several nuclear power plants between 1981 and 1989 by KWU. It was designed to act as heating supply in addition of generating electricity. Konvoi was expected for easier and shorter approval procedures on power plant construction, however it failed due to the federal structure of German approval law as different state licensing authorities led to significant differences. In 1987, KWU integrated into Siemens. Siemens later developed Baulinie 95 (Construction Line 95) or Advanced Konvoi with nominal electrical output of up to 1500 MW in 1991. Since 1996, Siemens collaborated with Framatome in EPR hence EPR is considered as descendant of KWU/Siemens Konvoi and Framatome N4 and retrofitted Konvoi technologies into Pre-Konvoi reactors. In 2001, Siemens and Framatome decided to create joint stock Framatome ANP, which later integrated Siemens nuclear business was merged into Framatome. +List of operational, planned, and closed Konvoi installationsPower plantReactorCapacity (MW)DateStatusNoteRefUnitCountryGeolocationModelGenBuildingOperationClosedIsar IIGermanyKWU Konvoi148215 Sep 19829 Apr 198815 Apr 2023Permanent ShutdownEmslandGermanyKWU Konvoi132910 Aug 198220 Jun 198815 Apr 2023Permanent ShutdownNeckarwestheim IIGermanyKWU Konvoi13109 Nov 198215 Apr 198915 Apr 2023Permanent Shutdown
