Traffic delays could happen around sunrise Thursday and Friday as a generator rotor for the main reactor at Grand Gulf Nuclear Station is moved from Vicksburg to the Claiborne County plant.

Entergy officials said the oversized load will leave the Kansas City Southern Railway yard on Levee Street Thursday morning and head north on Washington Street, south on U.S. 61 North, then west on Interstate 20. It will be parked at the Welcome Center before it is taken down U.S. 61 South to the Claiborne County nuclear plant on Friday, Entergy Nuclear spokesman Suzanne Anderson said. Vicksburg police will escort the load to the municipal limits.

A truck carrying the rotor will travel about 5 miles per hour and take up two full lanes of traffic. Once in Claiborne County, the escort will take Warner Tully Road.

The move is part of Grand Gulf’s continuing upgrade to its power generation capacity, expected to wrap up in 2012.
