DESCRIPTION OF PROGRAM OR FUNCTION - The Fuel Assembly Mechanical REsponse Code (FAMREC) calculates the lateral mechanical response of a row of fuel assemblies while allowing for two types of nonlinearities. The first type is a geometric nonlinearity in the form of gaps between individual assemblies and between peripheral assemblies and a boundary wall. Impacting is monitored across the gaps. The second nonlinearity is the permanent deformation of the fuel assembly spacer grid to compressive loading.
4.
METHOD OF SOLUTION - The response is calculated in the modal plane. The coupled differential equations are solved in closed form using Laplace transformations. The discrete displacements and velocities are then calculated and the gaps in the system monitored at each axial elevation for impacting. These impact forces are then applied statistically at a given time-step, and equilibrium is found using a Gaussian elimination technique.
5.
RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM - Maxima of - 6.
TYPICAL RUNNING TIME - Running time is not only problem dependent, but also dependent on which of the three available impact calculation procedures is selected. NESC executed the sample problem in 54 CP seconds on a CDC7600.
7.
UNUSUAL FEATURES OF THE PROGRAM - FAMREC was generated as an audit tool including three different methods for calculating impact forces to allow three levels of estimation.
8.
RELATED AND AUXILIARY PROGRAMS - Several of the subroutines in FAMREC are taken from the FORTRAN Matrix Analysis library (FORMA) developed at the Martin Marietta Corporation, Denver Division. The program uses the INEL-IGS graphics software for film-recorder plotting; the INEL-IGS routines are not part of this package.
