Pressurized water reactor
Description
The proposal concerns an improvement of the controllability of a PWR by conteracting the reactivity decrease of the control rods which may be caused by local xenon poisoning. It is proposed to add a time tapper to those control rods being effective along the whole length of the reactor core which will automatically cause a regular exchange of these control rods among themselves. The exchange may occur in regular intervals or on account of the determined local burn-up or according to the daily load diagram of the electric grid. (UWI)

Der Vorschlag betrifft eine Verbesserung der Regelbarkeit eines Druckwasserreaktors, indem der Absenkung der Reaktivitaet der Steuerstaebe - die durch lokale Xenonvergiftung verursacht werden kann - entgegengewirkt wird. Es wird vorgeschlagen, den Steuerstaeben, die ueber die ganze Laenge des Reaktorkerns wirksam sind, einen Taktgeber zuzuordnen, der selbsttaetig einen regelmaessigen Austausch dieser Staebe untereinander veranlasst. Der Austausch kann in regelmaessigen Abstaenden oder auf Grund des festgestellten lokalen Abbrands oder entsprechend der Tageslastkurve des elektrischen Netzes geschehen. (UWI)Files
