Syria's attempt at deception...
Here's an interesting article from the Washington Post about the deception used by Syria to hide its nuclear facility...
Syria went to extraordinary lengths to conceal its undeclared construction of a plutonium-producing nuclear reactor from spies in the sky and on the ground in recent years, according to a draft report by independent nuclear experts briefed by Bush administration officials.
The effectiveness of the camouflage effort raises new doubts about the prospects for certain detection of future clandestine nuclear weapons-related activities, the Institute for Science and International Security concluded in its report on the Syrian facility. "This case serves as a sobering reminder of the difficulty of identifying secret nuclear activities," the report said.
U.S. intelligence officials last month released images of the Syrian facility before it was bombed by Israel last September and bulldozed by the Syrian government once the raid became public. U.S. and Israeli officials have said the facility was a nearly completed nuclear reactor built with North Korean help and fitted with a false roof and walls that altered its shape when viewed from above.
According to the ISIS report to be released this week, the fake roof was just the start. Syrian engineers went to "astonishing lengths" to hide cooling and ventilation systems, power lines and other features that normally are telltale signs of a nuclear reactor, authors David Albright and Paul Brannan wrote.
For example, the main building appears small and shallow from the air, but it was evidently built over large underground chambers -- tens of meters in depth -- that were large enough to house the nuclear reactor, as well as a reserve water-storage tank and pools for spent fuel rods, the report said.
An extensive network of electrical lines appears to have been buried in trenches. Traditional water-cooling towers were replaced with an elaborate underground system that discharged into the Euphrates River. And, instead of using smokestack-like ventilation towers prominent at many reactor sites, the ventilation system appears to have been built along the walls of the building, with louver openings not visible from the air, the authors contended.
