The SOLA-PTS computer code has been developed to analyze fluid-thermal mixing in the cold legs and downcomer of pressurized water reactors in support of the pressurized thermal shock study. SOLA-PTS is a transient, three-dimensional code with the capability of resolving complex geometries using variable cell noding in the three coordinate directions. The computational procedure is second-order accurate and utilizes a state-of-the-art iteration method that allows rapid convergence to an accurate solution for the pressure field. Two different turbulence models are used in the code, a two-equation k-epsilon model that is used in the cold leg pipe away from the HPI inlet and a three-equation k-epsilon-T'/sup 2/ model for use near the HPI inlet and in the downcomer. The physical modeling and the numerical procedure used in SOLA-PTS are described in this report. Applications of the method to two Creare 1/5th-scale experiments are also presented. Two appendices are included which provides a comparison of the two- and three-equation turbulence models, and instructions for setting up and running a problem with SOLA-PTS.
