Why do UFOs / alien-like events seem to happen a lot around nuclear energy?

There’s a few cases where there’s a UFO spotted at a nuclear plant. Why is this?

For example, the event at the Pantex Nuclear Weapons Plant announcing a vague operational emergency with zero details because of an alleged UFO that Jeremy Corbell and George Knapp mention.

David Grusch also mentions an event happening related to nuclear weapons / atomic energy. What’s the idea here?
