OAK RIDGE, Tenn. — Nuclear operations were temporarily halted Wednesday at a Tennessee complex that stores and processes uranium after three protesters, including a nun, were able to intrude into a high-security area over the weekend. The Y-12 National Security Complex said all nuclear material is safe.
The temporary stand-down was expected to end by next week. Special nuclear material will be moved to vaults on site, and contractor security personnel will undergo training and refresher instruction.
