PIPESTRESS - Presentation
Generalities
Performs all calculations required by the nuclear (and non
nuclear) piping codes in a single program execution
Has
been continuously maintained for more than 40 years
Has
been used by more than 400 engineering organizations in 30
countries to analyze piping in more than 50 nuclear power
plants
Is
being used as the main piping analysis software for
calculations in the new reactors: EPR, AP1000 and AC-1000.
Many of the piping calculations for Westinghouse AP600 plant were
performed using PIPESTRESS and these calculations were accepted by the
US NRC when they issued a standard plant license for the AP600
Approved by the US NRC for AP1000 piping calculations
