Clean Energy for Sweden
Forsmark comprises three boiling water reactor units. The first two units were con-
nected to the grid in 1980 and 1981 with a net output of 961 MW and 954 MW
respectively. Another 1195 MW of power were added in 1985 by single-turbine
reactor unit 3. Right from the start, all major processes have involved numerous
KSB pumps of a variety of type series such as reactor coolant pumps, boiler feed
pumps, recirculation pumps and condensate pumps. The plant is also equipped
with some 600 valves made by KSB. All safety-relevant valves have been retrofitted
and updated continuously since 1995. For example by installing newly designed,
state-of-the-art valves with cobalt-free hard facing. Actuating force reserves have
been increased by retrofitting stronger spring return actuators, and new gate valves
are now supplied. Installation and commissioning were supervised by KSB service
specialists from Germany. Since the 90s, our service team in Sweden has been in
