Seabrook, New Hampshire

the nuclear power plant.
A neutron 'factory' generating lots of heat. Cooled by the Atlantic ocean. Neutron generation is probably moderated by carbon-graphite rods (or is it boron?) which absorb the neutrons and moderate the fission of uranium isotopes which decay on neutron absorption , with release of more neutrons, produce heat (to run steam turbines) as well as a variety of other radiation physics entities in a defined 'decay scheme'. Release of atmospheric Cesium from the decay is a tell tale sign of a leak in the system.

Another Spark Pilots member of this forum lives a few hundred kilometers southeast of Chernobyl (Ukraine) . Cesium isotope mapping places the track of contamination from Chernobyl on tracks , generally away from his location hundreds of kilometers south east from Kiev which is maybe 130 km from Chernobyl.

The Chernobyl reactor was enclosed in
a new containment structure so that robotic activities on the ruined core could go forward.

Long term (eternity) isotope confinement after use is a messy political and scientific topic even when planned responsibly (example Yucca Mountain containment). Transport by rail (and truck?) in well tested 'disposal containers ' is poorly received by communities through which the material would pass.
Who would want a Yucca mountain in their backyard?
I can't really remember all the key isotope decay steps from college physics but have the general process in mind.
