Westinghouse 2-loop
The Westinghouse 2-loop is a Generation II pressurised water reactor from Westinghouse Electric Company. 9 units are operating and 0 are under construction, out of 13 on record.
The smallest standard Westinghouse plant, two coolant loops and two steam generators, sold where the grid could not absorb a larger unit. It is the design that went furthest abroad relative to its size: Doel 1 and 2 in Belgium, Krško in Slovenia, Angra 1 in Brazil and Point Beach in Wisconsin are all the same plant. Several have run past fifty years.
