The following section contains Mechanical APDL solutions to NRC piping benchmark problems taken from publications NUREG/CR1677, Volumes 1 & 2 and NUREG/CR6645. The piping benchmark solutions given in NRC publications were obtained by using a computer program EPIPE which is a modification of the widely available program SAP IV specifically prepared to perform piping analyses.

The problems solved in this section range from simple to complex nuclear piping systems. The dynamic loading in these problems are induced by uniform earthquake type excitation in the three spatial directions. The solutions are determined by using the response spectrum method.

The test case description for each problem includes the element types, analysis types, input files, problem sketch, brief description of the problem and its geometry, material properties, and loadings. A results table is included at the end of the description of each test case.
