Encyclopedia
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.
