R1 (nuclear reactor)
R1 was the first nuclear reactor of Sweden. It was a research reactor located at the Royal Institute of Technology (KTH) campus at Valhallavägen in central , in the rock beneath the current-day Q buildings. The reactor was active from July 13, 1954 to June 6, 1970. The reactor was dismantled, and there is nothing left of it today; the reactor hall however still exists.
The capacity of the reactor was originally 300 kW but was later increased to 1 MW.
In 2016, the reactor hall was used to film the music video for Alan Walker's song Faded (Restrung). The video was released on 11 February 2016.
