Yes
Single greatest point of heat at each site
Fuel continues to heat water air and you since it was created.
Open ocean heat sinks, and lakes used to cool reacters rises sea temputures, and continues to feed this effect for it's lifetime
The longer it runs the more heat is generated.
Water that passes through these systems becomes tritiated. Which then broadens radioactive heating of oceans lakes and atmosphere. Contaminates fish and other life sucked through the system... People too!
Nutron flux... Gamma flux... And various other anomlies are exploited as a weapon for weather modifications and emp attacks. Also has an atmospheric heating effect. So much so, it creates gigantic high pressure zones on demand.
