KTH opens the doors to Sweden’s first nuclear reactor, the research reactor R1 at KTH Campus. Although now decommissioned and dismantled, the reactor still carries the spirit of research and experimentation. Today, KTH’s Reactor Hall serves as a creative meeting place – part museum, part cultural venue, seminar space, studio, and laboratory.
KTH’s Reactor Hall is truly one of a kind – steeped in history and defined by its stark grey concrete walls, grid-patterned ceilings and walls, and a complete absence of mobile reception. The coordinate system still visible on the ceiling is a remnant from the measurements of radioactive radiation carried out before the reactor was shut down.
During the visit on 8 October, you will also see Sweden’s most powerful supercomputer, testbeds for future digital infrastructures and cyber-physical systems (TECoSA), as well as the historic KTH Reactor Hall itself.
Two guided tours will be offered at 16:30 and 17:30. Each tour of the reactor hall is limited to 20 participants. Advance registration is required.
Free admission.
The tour is offered in English.
