OSCIL and OSCVERT: computer codes to evaluate the non-linear seismic response of an HTGR core
OSCIL and OSCVERT are FORTRAN codes which simulate the effects of seismic input on a High Temperature Gas Cooled Reactor (HTGR) core. The analysis, in conjunction with results of experimental scale models, is to be used to determine safety standards and licensing regulations for HTGR. OSCIL models the core as a horizontal one-dimensional non-linear spring-mass system with friction. OSCVERT is the two-dimensional extension, with each mass in OSCIL expanded to a vertical column of blocks. An important feature of OSCVERT is that large rotations are allowed. The codes use a powerful integration scheme due to GEAR. This permits very stiff springs, as well as transients (''jump'' phenomena) due to multiple solutions that arise in non-linear systems, to be incorporated in the codes. Either code can be used more generally to analyze the non-linear dynamic response of a spring-mass system excited by boundary motions.
