The Kewaunee Power Station.
Nuclear fuel rods were removed from the reactor at Kewaunee Power Station last week and a majority of contractors left the plant Friday.
Dominion Resources said in October it would shutter the plant after failing to find a buyer during an 18-month search.
The fuel rods will remain in the spent fuel pool in the plant for at least seven years, after which they will be put into dry-cask storage on the site.
The plant contracted with hundreds of temporary workers to help prepare the plant for permanent shutdown.
Dominion notified the state Department of Workforce Development that 202 of 632 permanent workers are scheduled to be laid off at the end of May. Those layoffs would be followed by 56 by June 30, 46 by July 31, 31 between August and December, five by Sept. 30, 2014, and 293 on Sept. 30, 2014, or later.
