Description

Vibration monitoring systems are available in German PWR type reactors. Their task is the early detection of faults in structures and rotors. Long pre-warning times can be achieved through appropriate construction, careful frequency measurements and the choice of sensitive monitor values. The portrayable results of the analysis are compared with the attention threshold. If this threshold is exceeded a signal is generated. (orig./HP)

Abstract (German)

In deutschen Druckwasserreaktoren stehen Schwingungsueberwachungssysteme zur Verfuegung, deren Aufgabe es ist, sich an Strukturen und Rotoren anbahnende Veraenderungen zum fruehestmoeglichen Zeitpunkt anzuzeigen. Lange Vorwarnzeiten werden durch Einsatz geeigneter Einrichtungen, sinnvolle Messhaeufigkeiten und Wahl sensibler Ueberwachungskenngroessen erreicht. Die darstellbaren Analyseergebnisse werden mit Aufmerksamkeitsschwellen verglichen. Schwellenueberschreitung fuehrt zu Diagnoseaussagen. (orig./HP)
