The company that manages the former nuclear weapons complex near Augusta says it's laying off 1,400 contractors next year.
Savannah River Nuclear Solutions announced the news Wednesday in a memorandum to employees.
The memo said the company is offering severance packages to people who volunteer to leave or retire starting next week.
Two rounds of layoffs are planned in 2011.
Savannah River Nuclear Solutions manages the Savannah River Site, which once produced plutonium and tritium for atomic bombs.
Work there is now focused mostly on research and environmental cleanup.
The site received $1.6 billion in stimulus cash to create and save about 3,000 jobs.
The company didn't specify how many of the 1,400 jobs are stimulus-funded.
