This chapter discusses an example of public outreach, which happened on the campus of KTH Royal Institute of Technology in Stockholm in pre-pandemic times on 05 June 2019. The event took place 25 metres under the university in an artificial cave, which was constructed to host Sweden’s first nuclear reactor. In R1’s former reactor hall, the place where part of the Swedish nuclear bomb project was researched during the 1950s, a viewing of the final episode of HBO’s Chernobyl-series and a subsequent podium discussion were organised.
