(AP) — Some workers at a nuclear weapons production site in Washington state were ordered to stay inside Friday because steam escaped from a tunnel with radioactive waste as it was being filled with cement, officials said. > There no indication that the steam seen at the Hanford Nuclear Reservation contained radiation or any other hazardous material, and the workers were ordered inside as a precaution, the U.S. Department of Energy said in a statement.
