Leibstadt nuclear power station in operation: experience and consequences for future nuclear plant projects

The Leibstadt nuclear power station was handed over to the customer for commercial operation in December 1984. Due to its exceptional performance the plant's net rating was raised from 942 MW to 990 MW. The authors describe the experience gained during the final construction period, during commissioning and in the first 18 months of operation. The main reasons for the projected cost and schedule being exceeded are discussed, together with lessons learned and conclusions to be drawn for future projects. (Auth.)
