Technicians upgrading Iran's main uranium enrichment facility have tripled their installations of high-tech machines that could be used in a nuclear weapons program to more than 600 in the past three months, diplomats said Wednesday.
Iranian scientists have run computer simulations for a nuclear weapon that would produce more than triple the explosive force of the World War II bomb that destroyed Hiroshima, according to a diagram obtained by The Associated Press.

Recent disclosures that North Korea is building a light-water reactor and centrifuge facility to produce uranium fuel for bombs has confirmed what critics say are significant failures of U.S. intelligence and diplomacy since 2002 to identify and halt Pyongyang's nuclear program.

Scientists, engineers and financiers involved in the A.Q. Khan nuclear-smuggling network are being contacted by several governments in an effort to lure these specialists out of retirement.
Mr. Albright on Wednesday said Iran's apparent ability to mass-produce the machines reflects its success in evading sanctions.
Mr. Albright, who occasionally briefs U.S. government officials on Iran's nuclear program, said much of the material appears to be coming through China from European and Japanese manufacturers.
