Oh good, because 2020 was such a delightful year so far. Now we get to have a Chernobyl rerun!

jogri:
Hmm, another option would be that someone screwed up the disassembly of a nuclear sub:

-In order to get such a leak in a normal power plant you have to have a leak in both the fuel cell AND the primary cooling loop, and you normally have detectors to detect if a fuel cell is leaking into the water-> rather unlikely that someone didn't detect the leak AND someone accidentally vented the primary cooling system.

-nuclear subs get disassembled in the Kola bay (right at the border to Finland, most northern point), that region is not too far away from the 72h source region

-most subs use highly enriched U-235, you get the same fission products as normal nuclear power plants

-would also explain the Russian statement that both power plants are working normally

Let's top off 2020 with a nuclear accident.  As if Covid-19 and the associated economic disaster wasn't enough.

Porenbeton:
Lets just hope that its just a instrumentation fault or the reading comes from some not yet considered/found source (like jogri said, nuclear fission powered submarines sound plausible).
I doubt that it could be a plant, they dont build them like they used to when chernobyl was still operating, the plant in chernobyl had positive feedback considering the temperature/power curve.
Meaning increase in temperature would increase the power, which would again increase temperature and so on until meltdown. So afaik catastrophic meltdown shouldnt be actually possible with modern reactors (but im not an expert obviously so that is only a thought), since they should react the opposite way (higher temperature -> decrease in power output).

Also this isnt the 80s anymore with communist russia. I think if something in this scale happened, that it wouldnt take even 5 minutes until the social medias are full of it with videos/pictures etc.
