Unsteady Single-Phase Natural Circulation Flow Mixing Prediction Using CATHARE Three-Dimensional Capabilities

Autor: Anis Bousbia Salah, Jacques Vlassenbroeck

Publikováno v: Nuclear Engineering and Technology, Vol 49, Iss 3, Pp 466-475 (2017)

Coolant mixing under natural circulation flow regime constitutes a key parameter that may play a role in the course of an accidental transient in a nuclear pressurized water reactor. This issue has motivated some experimental investigations carried o
