Title: R5FORCE/MOD3s: A program to compute fluid induced forces using hydrodynamic output from the RELAP5/MOD3 code
Abstract: This report describes an update of a computer program which operates on hydrodynamic output from the RELAPS/MOD3 program and computes piping hydrodynamic force/time histories for input into various structural analysis codes. This version of the program is compatible with RELAPS/MOD3 and the Micro Vax computing environment whereas an earlier version of the program was compatible with RELAPS/MOD1. The report describes the force calculation theory, showing the development of a general force equation and the solution of this equation within the RELAPS output structure. To illustrate the calculational method and provide results for discussion, a sample problem is presented. A detailed user manual for the computer program is included as an appendix. 10 refs., 17 figs.
