Diablo Canyon Power Plant, which is situated in a postcard-perfect location on the central California coastline, generates electricity for more than three million households in central and northern California. In 2009 the project team at the dual-unit Westinghouse pressurized water reactor facility replaced four steam generators at Unit 1 in just 58 days. Through meticulous planning and excellent project execution, performance on this Unit 1 project was an improvement on the earlier Unit 2 steam generator replacement project.
