The Omaha Public Power District finished another round of testing at the troubled Fort Calhoun Nuclear Station earlier this week, and the results were encouraging.
The district began heating up the plant Oct. 29 — the first time in 2 1/2 years — with the aim of testing the pipes that carry pressurized water and steam to cool the reactor. The plant was cooled down Monday.
“No significant issues,” U.S. Nuclear Regulatory Commission spokeswoman Lara Uselding said.
The plant did not produce power during the heat-up.
Fort Calhoun has been shut down since April 2011, when it was taken offline for a scheduled refueling. It was kept cold after extensive flooding on the Missouri River, then placed under federal control after an electrical fire and the discovery of a number of safety violations.
It’s unknown when it will reopen.
“We’ll keep working on closing out paperwork,” OPPD spokesman Jeff Hanson said.
At last check, federal inspectors had cleared about 70 percent of the items on a long checklist of corrections that OPPD must complete before restarting. Uselding said the NRC is planning another public update in the coming weeks.
