"They can't build those plants. There's no way."

Iran’s bold announcement Sunday appears to be largely impossible to achieve as long as sanctions continue to throw up roadblocks and force Iran to turn to black markets and smuggling for nuclear equipment, said nuclear expert David Albright.

“They can’t build those plants. There’s no way,” he said. “They have sanctions to overcome, they have technical problems. They have to buy things overseas … and increasingly it’s all illegal.”…

“And also they don’t have enough uranium. They would need a massive amount of uranium,” he said…

Still, the announcement is of major concern because it could signal an intention to put up numerous decoy sites to deceive the outside world, while building perhaps a few secret military enrichment sites on a small scale that could be put to use in weapons production if Tehran decides to do go down that path, Albright said.
