WASHINGTON — When diplomats at the Iran talks in Switzerland pummeled Department of Energy scientists with difficult technical questions — like how to keep Iran’s nuclear plants open but ensure that the country was still a year away from building a bomb — the scientists at times turned to a secret replica of Iran’s nuclear facilities built deep in the forests of Tennessee.

There inside a gleaming plant at the Oak Ridge nuclear reservation were giant centrifuges — some surrendered more than a decade ago by Libya, others built since — that helped the scientists come up with what they told President Obama were the “best reasonable” estimates of Iran’s real-life ability to race for a weapon under different scenarios.

“We know a lot more about Iranian centrifuges than we would otherwise,” said a senior nuclear specialist familiar with the forested site and its covert operations.
