The vast majority of nuclear reactors would run off their own power supply and when some fault occurs the rods would drop and the reactor would SCRAM. There it would sit safe for thousands of years until reinforced concrete started to fail.

As days pass, domestic dogs eat all easily available food and begin to fight amongst each other for supremacy. The bigger dogs make packs and attack and eat the small ones. Within a week, all
toy dogs disappear from Earth. Large packs of dogs also feed on dead penned up cattle.
Security measures in power plants fail. The equipment in the spent fuel buildings adjoining nuclear power plants that maintain the temperature level of the spent nuclear fuel rods will shut down.
Spent nuclear fuel for
nuclear power plants is generally stored in pools in on-site facilities. Because the fossil fuel powered back up, power generators will run out. At that time, the cooling pools that prevent the spent nuclear fuel from overheating will start to boil since this water is not replenished.
Radioactive steam will vent into the atmosphere due to the water eventually evaporating. The spent fuel will eventually set fire to the building, and the
steam pressure will cause the storage facilities to explode, causing a (non nuclear) explosion, emitting radiation not only in the immediate area of the plant but around the globe due to winds. The resulting
nuclear disasters spread fallout over large areas. This is repeated dozens of times as shutdown nuclear plants and spent fuel houses explode.
Radioactive clouds cross the skies and
rain carries the
radiation to the ground. Most plants and small animals within the affected zones die. Larger animals (like
deer) flee to unaffected regions, not because they notice the radiation, but because of the lack of food.
