The focus of activities increasingly shifts to the Studsvik site.
The Ågesta reactor is constructed and taken into operation together with Vattenfall and Stockholm Energi AB, and the uranium mine at Ranstad is set up and operated by the company. Towards the end of this period, the heavy water concept is abandoned in favor of the internationally dominant light water technology. Most of the company's know-how can also be directly applied to this area.
ASEA-ATOM is formed - 50 % government- and 50 % state-owned - and takes over the company's resources for fuel fabrication and commercial reactor design. The state assumes all shareholdings in the company. The future direction of the company is to provide R & D and consulting to the Swedish nuclear power sector.
