Gov't posts sensitive list of US nuclear sites - Yahoo! News WASHINGTON â€“ The government accidentally posted on the Internet a list of all civilian nuclear sites and their activities in the United States. The 266-page document was published on May 6 as a transmission from President Barack Obama to the U.S. Congress. According to the document, the list was required by law and will be provided to the International Atomic Energy Agency. Some of the pages are marked "highly confidential safeguards sensitive." While there is security at the facilities, the list could presumably be useful for terrorists or anyone else who would like to harm the United States.
