SPORTS - A simple non-linear thermalhydraulic stability code

Experimental and numerical investigations on flashing-induced instabilities in a single channel

“…Manera [18] has presented a complete review of the numerical efforts in the field, which is partially reproduced here. Chatoorgoon [3] developed a simple timedomain code, SPORT, based on HEM formulation, which includes single-phase circulation and pressure-dependent thermodynamic properties along the axis of the system. Chatoorgoon shows that the code is able to reproduce flashing instabilities at low pressure and low power, but no systematic parametric study is performed and no comparison with experimental results is shown.…”

Computational investigation of the dynamic response of a supercritical natural circulation loop to aperiodic and periodic excitations

“…Conservation equations are converted to algebraic forms following the methodology adopted in the SPORTS code (Chatoorgoon, 1986), i.e., control volume discretization in space and forward difference in time. Resultant finite difference representations of the steady-state equations are the followings.…”

Analysis of parallel channel instabilities in the CANDU supercritical water reactor

“…The supercritical flow behavior was analyzed by , using a time-domain 1-D TH model. A similar model, known as SPORTS, was developed for the boiling water reactor (BWR) by Chatoorgoon (1986). SPORTS is based on a nonlinear model and it accounts for thermodynamic property variations due to the pressure and temperature, but adopts a shooting method in transient solution algorithm while imposing the relevant BCs.…”
