Modellierung, Simulation und Fehleranalyse des Naturumlaufsystems bei Ridham

Abweichender Titel nach Übersetzung der Verfasserin/des VerfassersThis master thesis investigates the circulation issues that were encountered at a natural circulation steam generator at the Ridham Docks site (England), causing heat damage. The evaporator of the steam generator was modeled in detail and numerically simulated using state of the art calculation software. While no conclusive evidence was found that could explain the damages unambiguously, other instabilities were discovered that may have contributed to the phenomenon. General design guidelines were deducted as possible solutions to the problem.13
