Just a couple years before the first invasion of Ukraine. Wouldn't it have been nice in 2022 when the Nordstream pipelines stopped?
Maybe this is already complete, but at one point of lot of it was from decommissioning nuclear weapons, so it wasn't "we need them for fuel", it was "lets make use of this waste material and provide a financial disincentive for nuclear proliferation".
Finally, the West has plenty of sources for Uranium, and given plants already have years of fuel onsite, it is never a pressing problem.
