Availability Notice


New models for Pressurized Water Reactor (PWR) with fully 3D cores were developed using TRACE thermal-hydraulic code. To develop these new models, TRACE code was chosen because it is been developed and will be probably licensed by the Nuclear Regulatory Commission (NRC). Thus, it is easy to take advantage of current and future features of TRACE. Three 3D different models were developed, they make use of the 3D vessel component in TRACE, either cartesian or cylindrical type. These models are especially suitable to simulate cross-flow, instabilities and in general asymmetric phenomena. All three models have been successfully tested.
