Fort Calhoun nuclear plant goes offline for repairs

The Omaha Public Power District (OPPD) has removed the Fort Calhoun nuclear plant in Nebraska from service on July 20 to repair a water leak on one of the plant’s four reactor coolant pumps.

Reactor coolant pumps move water through the plant as part of the reactor coolant system. The water was kept inside the plant’s containment structure, where it was collected and treated.

Fort Calhoun is a roughly 500-MW pressurized water reactor (PWR) in Washington County, Neb. Its primary water source is the Missouri River. OPPD recently signed a maintenance and upkeep agreement with Chicago Bridge & Iron (NYSE:CBI).  

The timing of this maintenance outage was coordinated with the Southwest Power Pool (SPP) to ensure reliability of the electrical grid. This maintenance outage will not cause an interruption of electrical service to OPPD customers as any additional energy can be purchased through the grid.

The duration of the maintenance outage depends on the extent of the repairs required, OPPD said in a news release.

OPPD is one of the largest customer-owned electric utilities in the United States, serving more than 360,000 customers in 13 counties in southeast Nebraska.
