I first learned about Sellafield when I tried to decipher what name Kraftwerk was saying in their song "Radio-Activity" (along with Hiroshima, Chernobyl, and Harrisburg (Three Mile Island)) https://youtu.be/X--F5b5IdqU?si=P6DoR6-VXUC1b50I
Pretty cynical from my side.
But re: Kraftwerk: that tune is pretty good IMO! I like the original as well as the 90s remix and discovered both of them as a kid. The soothing ethereal synth melodies and the scary theme of the title go so well together, eerily.
