The WCOBRA/TRAC code is a best-estimate thermal hydraulic code for the evaluation of consequences of a large-break loss-of-coolant accident. The code has been applied to a smalll-break analysis of the most limiting small-break scenario of an AP600 plant. For this purpose, a series of performance tests of the code and models was carried out on key components such as the pressurizer, the core makeup tank (CMT), and the hot- and cold-leg pipes. The hot legs and the cold legs, for example, were modeled with three-dimensional vessel cells so that small-break concerns such as steam/water separation were addressed.
