Moonquakes are smaller than Earth and don't seem common. This is very low on the list of risks. A meltdown on the Moon wouldn't be nearly as bad as Earth. The thing that makes it bad here is all the water, wind, etc. and the thick atmosphere that spreads nasty radioactive material everywhere. On the Moon you would end up with one site that was radioactive AF but it wouldn't go everywhere unless it exploded and a reactor prone to that would be stupid. Different reactor designs would be much easier on the Moon too like liquid sodium fast reactors. Liquid sodium is problematic on Earth because it loves to react with water and oxygen but on the Moon if it were exposed it would just sit there. Of course the whole surface environment is bathed in radiation because it's sitting underneath an unshielded open fusion reactor called the Sun. This also makes radiation incidents less of a concern. It doesn't change all that much except for right next to the thing. Edit: BTW I do think if solar towers at peaks of eternal light work that's probably easier than a nuclear reactor at least in the short-medium term and maybe forever.
