• R1 Reactor in Nucleus IAEA-Database (IAEA Code SE0004)

"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 Stockholm, in the rock beneath the current-day Q-Houses. 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 effect of the reactor was originally 300 kW but was later increased to 1 MW."
