“... 3 Mile Island which is STILL not cleaned up enough to walk your dog through it.”

BTW, cleanup ended in December 1993. Three Mile Island Generating Station Unit 1 continued operation until September 20, 2019. It is, literally, an island and is privately owned. So, I don’t think walking your dog there is even an option. Though part of the island isn’t locked off and guarded, so I guess it is.
“... with no real place to store nuke waste for 100,000 years”

3 Mile Island Cleanup
A clean-up crew working to remove radioactive contamination at Three Mile Island
Initially, GPU planned to repair the reactor and return it into service.[99] However, Three Mile Island Unit 2 was too badly damaged and contaminated to resume operations; the reactor was gradually deactivated and permanently closed. TMI-2 had been online for only 3 months but now had a ruined reactor vessel and a containment building that was unsafe to walk in. Cleanup started in August 1979 and officially ended in December 1993, with a total cleanup cost of about $1 billion.[18] Benjamin K. Sovacool, in his 2007 preliminary assessment of major energy accidents, estimated that the TMI accident caused a total of $2.4 billion in property damages.[100]
Efforts focused on the cleanup and decontamination of the site, especially the defueling of the damaged reactor. Starting in 1985, almost 100 short tons (91 t) of radioactive fuel were removed from the site. Planning and work was partially hampered by too optimistic views about the damage.[101]
In 1988, the Nuclear Regulatory Commission announced that, although it was possible to further decontaminate the Unit 2 site, the remaining radioactivity had been sufficiently contained as to pose no threat to public health and safety. The first major phase of the cleanup was completed in 1990, when workers finished shipping 150 short tons (140 t) of radioactive wreckage to Idaho for storage at the Department of Energy’s National Engineering Laboratory. However, the contaminated cooling water that leaked into the containment building had seeped into the building’s concrete, leaving the radioactive residue too impractical to remove. Accordingly, further cleanup efforts were deferred to allow for decay of the radiation levels and to take advantage of the potential economic benefits of retiring both Unit 1 and Unit 2 together.[18]
