Last I read none of the closed plants in the USA had been completely decommissioned. The Trojan Nuclear Power Plant[1] in Oregon comes "close" to being decommissioned. E.g. the reactor vessel itself was barged up the Columbia River and dumped into a big pit in the ground. Of course, the spent nuclear fuel remains on site. But that's a political issue, not a technical one. [1] https://en.wikipedia.org/wiki/Trojan_Nuclear_Power_Plant https://en.wikipedia.org/wiki/Trojan_Nuclear_Power_Plant
