MARSEILLES, Ill. (Jan. 19, 2009) - Operators safely shut down LaSalle County Generating Station Unit 2 for a scheduled refueling and maintenance outage shortly after midnight this morning.
This shutdown completes the end of the second consecutive breaker-to-breaker run for LaSalle Unit 2, which means that the unit has operated continuously between 24-month cycles. Both LaSalle Station operating units hold the top two spots worldwide for longest continuous runs of light-water reactors. LaSalle Unit 1 holds the world record (739 days) while Unit 2 is second (711 days).
"We are ready to execute this outage safely and efficiently," said site vice president Dan Enright. "A successful refueling outage will enable us to safely and reliably operate the unit during the next two years. The power we produce will help the environment by reducing dependence on other energy sources that emit air pollution like nitrogen oxide and sulfur dioxide."
During the outage, workers will perform extensive inspections, testing and maintenance on a wide range of components and equipment in addition to refueling the reactor. Many of the activities performed during the shutdown cannot be performed while the unit is running and all are designed to ensure the safe and reliable production of electricity through its operating cycle.
A LaSalle Station outage brings 1,600 additional talented, skilled workers from other Exelon sites, local union halls, travelers from outside the area and specialized vendors. They all provide a temporary benefit for the local economy during the shutdown.
LaSalle Unit 1 will continue to generate electricity during the Unit 2 shutdown. LaSalle County Generating Station is located approximately 75 miles southwest of Chicago. With both units at full power, the site can produce enough electricity for 2.3 million homes.
