David Albright, a former weapons inspector in Iraq, says 24 days is enough time for Iran to wipe out traces of nuclear work, such as working with explosives to trigger a weapon or construction of a small plant to make centrifuges. A situation actually happened in 2003 when the atomic energy agency wanted to inspect the Kalaye Electric Company site in Iran in 2003, where Iran was using centrifuges received from Pakistan. Iranians removed all traces of illicit work at the time while delaying inspectors. This case was cited by Olli Heinonen, a former deputy director of the agency. Heinonen says smaller scale activity such as manufacturing uranium components for a nuclear weapon can be carried out and the traces deleted in 24 days. Senator Corker points out that the time allowed would be more than 24 days when all the time is added up correctly.
