| Bechtel sets record for fastest steam generator replacement Texas-based Comanche Peak Steam Electric Station is up and running following a modernization project managed by Bechtel Power Corp. Working with TXU, the plant's owner, a Bechtel team replaced four steam generators and a reactor head during a planned outage that lasted just 55 dayseight days less than the previous record for steam generator replacement. Located about 60 miles southwest of Dallas, Comanche Peak features two units, each capable of generating approximately 1200 megawatts of electricity. The project involved replacing the steam generators in Unit 1, each of which was about 70 feet long and 15 feet in diameter and weighed around 400 tons. The four new high-efficiency steam generators were built in Spain. They traveled by ocean to Houston and continued to Comanche Peak via special train. The new reactor head, also fabricated in Spain, was outfitted with new control rod drives in Pennsylvania and transported by barge to Houston, then trucked to the site. write your comments about the article :: © 2007 Construction News :: home page |
