We’ve known what to do with nuclear waste for a very long time. In the US at least, its more a question of politics and funding. Basically, we can: * Bury all of it (deep geological repository, bore holes) * Reprocess fuel, take out the rem

France’s oldest operating reactors are in the 900 MWe range, so more like 3. Their newer fleet is 1300 and 1450 (now 1500) MWe, plus the 1600 MWe EPR under construction at Flamanville. The 300 MWe NuWard really only makes sense as an export

Honestly, you could just Google it… it’s not exactly a secret where the nukes and their various major subcomponents components live. Pantex, Y-12, LANL, etc.

Have you thought about adding some kind of room-temperature spectroscopy along with your Geiger counter? Might be interesting to correlate with spikes in the count rate.
