Kernkraftwerk Obrigheim (KWO) GmbH. Annual report 1991

The Obrigheim nuclear power station was operated at full load from August 21 through Dec. 31, 1991, generating 1.108 GWh of electrical energy in 3.186 operating hours. The Obrigheim nuclear power station thus achieved during this period of 133 days in 1991 an operating availability of 100%. Since its commissioning in October 1968, the Obrigheim reactor station has been operating for 161.527 hours, generating 54.409 GWh (gross), and from test operation started in March 1969 up to the end of 1991, all in all 54.284 GWh have been generated in 160.747 operating hours, which means an availability time ratio of 78.2%, and a capacity factor of 80.4%. The plant was shut down in 1991 for the 21st refuelling operation including inspection and repair work, for a fictitious period of 1783 hours. In addition, power operation was stopped by an order of the supervisory authority for another 3.791 hours, so that the plant remained disconnected from the grid between Januar 1 and August 8, 1991. In the last part of the year 1991, until May 26, the plant had an excellent availability time ratio and thus contributed about 2.5% of the safe, economic and environmentally sound electricity supplies in Baden-Wuerttemberg.
