U.S. Web Archive Is Said to Reveal a Nuclear Primer
By WILLIAM J. BROAD

Last March, the federal government set up a Web site to make public a vast archive of Iraqi documents captured during the war. The Bush administration did so under pressure from Congressional Republicans who had said they hoped to “leverage the Internet” to find new evidence of the prewar dangers posed by Saddam Hussein.

But in recent weeks, the site has posted some documents that weapons experts say are a danger themselves: detailed accounts of Iraq’s secret nuclear research before the 1991 Persian Gulf war. The documents, the experts say, constitute a basic guide to building an atom bomb.

Last night, the government shut down the Web site after The New York Times asked about complaints from weapons experts and arms-control officials. A spokesman for the director of national intelligence said access to the site had been suspended “pending a review to ensure its content is appropriate for public viewing.”

Officials of the International Atomic Energy Agency, fearing that the information could help states like Iran develop nuclear arms, had privately protested last week to the American ambassador to the agency, according to European diplomats who spoke on condition of anonymity because of the issue’s sensitivity. One diplomat said the agency’s technical experts “were shocked” at the public disclosures.

Early this morning, a spokesman for Gregory L. Schulte, the American ambassador, denied that anyone from the agency had approached Mr. Schulte about the Web site.

The documents, roughly a dozen in number, contain charts, diagrams, equations and lengthy narratives about bomb building that nuclear experts who have viewed them say go beyond what is available elsewhere on the Internet and in other public forums. For instance, the papers give detailed information on how to build nuclear firing circuits and triggering explosives, as well as the radioactive cores of atom bombs.

The Web site, “Operation Iraqi Freedom Document Portal,” was a constantly expanding portrait of prewar Iraq. Its many thousands of documents included everything from a collection of religious and nationalistic poetry to instructions for the repair of parachutes to handwritten notes from Mr. Hussein’s intelligence service. It became a popular quarry for a legion of bloggers, translators and amateur historians.

In Europe, a senior diplomat said atomic experts there had studied the nuclear documents on the Web site and judged their public release as potentially dangerous. “It’s a cookbook,” said the diplomat, who spoke on condition of anonymity because of his agency’s rules. “If you had this, it would short-circuit a lot of things.”

A senior American intelligence official who deals routinely with atomic issues said the documents showed “where the Iraqis failed and how to get around the failures.” The documents, he added, could perhaps help Iran or other nations making a serious effort to develop nuclear arms, but probably not terrorists or poorly equipped states.
