From the Wall Street Journal 6/3/2009 titled "Nuclear Sites Posted Online Accidentally" By Stephen Power and Jonathan Weisman ( http://online.wsj.com/article/SB124400117312880465.html )
Apparently a government office accidentally made public a report that gave detailed information about the United State's civilian nuclear sites and programs.
"The report, which includes maps of facilities showing the locations of stockpiles of fuel for nuclear weapons at those facilities, was posted last month on the Web site of the Government Printing Office. It was removed from the site late Tuesday, after the Federation of American Scientists reported on the document's existence Sunday in an online bulletin."
The Obama administration made an agreement to encourage other countrys to comply with a decade old international agreement to provide the International Atomic Energy Agency with information on all nuclear related activity.
The report that was made public was marked "Highly Confidential Safeguards Sensitive". I don't know about you, but I might have gotten that cleared or declassified before putting it on a public government web site. Better yet, not at all.
" The list details the existence of nuclear facilities at the Oak Ridge National Laboratory in Tennessee, Los Alamos National Laboratory in New Mexico, Argonne National Laboratory in Illinois and a Westinghouse research facility in Pittsburgh, among others."
I'm thinking, any group (terrorist) that is monitoring government web sites may have already downloaded the information as it was posted for nearly a month. But hey, don't worry. Fearless leader's gang says it didn't jeopardize national security so, don't worry about it.
