Wilson announced the change Tuesday in an address to SRNS employees, according to a news release. He is leaving for another position with Fluor Corp., one of the three companies making up SRNS.
SRNS manages solid-waste cleanup efforts at Savannah River Site.
Wilson will remain at SRNS until mid-to-late June, when a successor has been named.
During his three-year tenure at SRNS, Wilson oversaw renewal of H-Canyon operations and continued support of the Savannah River Tritium Enterprise and completion of Cold War-era cleanup funded by the American Recovery and Reinvestment Act.
He also focused on expanding the Savannah River National Laboratory.
In 2013, Wilson was recognized by the National Safety Council for a safety award called “CEOs Who Get It,” based on his strong commitment to safety at the U.S. Department of Energy site.
