Savannah River Site’s security contractor, Wackenhut Services Inc., will furlough 270 of its 700-person workforce effective Monday.
The furloughs will remain intact until progress is made in resolving the budget impasse in Washington.
“The Department of Energy directed the company to ramp down operations to perform only those activities necessary to protect DOE security interests at the site based on the current reduction of site operations,” a site spokesman said in a statement Friday.
Wackenhut employees needed to protect security interests and operations at the nuclear site will not be furloughed, officials said.
Impacts of the furloughs include closure of some access points.
In a communication to employees, officials said barricade 8 (Road 2 and Highway 125) and Barricade 10 (Road 1 and 1A, Augusta side) will be closed at midnight on Sunday and remain closed until further notice.
Employees should plan on using alternate barricades during this period, officials said.
Wackenhut is the second major employer at the site to furlough workers.
On Oct. 3, liquid waste contractor Savannah River Remediation furloughed about 1,400 of its workers, leaving just 360 employees to oversee programs that include managing high-level radioactive waste in underground storage tanks.
Savannah River Site’s largest contractor, Savannah River Nuclear Solutions, notified employees this week that carryover funding should maintain the workforce until late October, after which furloughs and other steps could be necessary if the budget stalemate isn’t resolved.
