Mello, R. M.

The CRBRP heat transport system piping was designed and analyzed for the operating and load conditions as specified in the Piping Design Specification. The various types of design loading conditions have been categorized into design, normal, upset, emergency and faulted conditions, and organized into a load histogram. Using the thermal transient defined for each condition and the histogram, a set of load cycles was constructed using the 863 startup-shutdown conditions. The stress analysis of the piping was performed on the basis of the thermal transients and loadings resulting from the loading categories and the histogram. The ELTEMP computer program was used to perform the elastic ASME Code compliance analysis. The input required to perform the Code evaluation included the pipe cross-section geometry, component type (elbow, tee, straight, etc.), the forces and moments output data from the flexibility analyses, average temperature, linear temperature gradients, non-linear temperature gradients, pressure, etc.
