The federal government mistakenly made public a 266-page report, its pages marked “highly confidential,” that gives detailed information about hundreds of the nation’s civilian nuclear sites and programs, including maps showing the precise locations of stockpiles of fuel for nuclear weapons.
The publication of the document was revealed Monday in an on-line newsletter devoted to issues of federal secrecy. That publicity set off a debate among nuclear experts about what dangers, if any, the disclosures posed. It also prompted a flurry of investigations in Washington into why the document was made public.
