Topeka ? The Wolf Creek nuclear reactor is shut down after power transmission lines from the plant were hit by lightning, officials said Thursday.

The lines, which carry power produced by the plant, stopped working Wednesday after the lightning strikes. Once those lines stopped working, that in turn, started the shut down of the plant.

“The plant responded exactly as it is designed and shut down appropriately,” said Jenny Hageman, a spokesperson for the Wolf Creek Operating Corp. “All the safety systems kicked in just as they should and the operators took all the appropriate actions,” she added.

Operators were working Thursday to bring the plant back online, but there was no estimate as to how long that would take, she said.

Wolf Creek is a 1,200 megawatt nuclear plant that is located near Burlington. The plant is owned by Westar Energy, Kansas City Power & Light and the Kansas Electric Power Cooperative.
