The nuclear power plant shut down last Wednesday, due to a main generator lockout. Officials believe moisture got into a transformer control cabinet, which automatically tripped the reactor offline.
The down time wasn’t wasted, according to the Omaha Public Power District. It reports workers took advantage of the plant going offline to complete some minor maintenance.
Once repairs were made, operators restarted the nuclear reactor and slowly brought the plant back to life, reaching full power early Monday morning.
OPPD serves about 350,000 customers in southeast Nebraska. The shutdown didn’t affect electrical power to any customers.
