The Forsmark 3 reactor plant

The 3000 MW(th) power station Forsmark 3 is the first nuclear power plant to be based on the third generation of boiling water reactors, designated BWR 75, developed by the Swedish company ASEA-Atom. Although a new design, the BWR 75 is largely based on proven components and system layouts, e.g. the reactor fuel, the main recirculation pumps, the control rod drives, the reactor containment and the water clean-up systems, which are described. The Forsmark 3 plant and buildings are laid out and designed to balance function, safety and construction methods. Details are given of the emergency cooling systems, the reactor protection system and of the system of fire protection. (U.K.)
