Abstract
Sipping tests have been performed for fuel elements of the TR-2 reactor at Çekmece Nuclear Research and Training Center (ÇNRTC), in order to find out which one failed in the core. A sipping assembly has been constructed and placed in the pool of the TR-2 reactor. The assembly identifies leaking fuel elements by collecting and measuring 137Cs that leak out from the defective fuel elements. 31 fuel elements in the reactor have been tested for the clad integrity. The measured 137Cs activity of the fuel element with an identification number S-104 is a 10247 Bq/(0.3 l). This value is approximately 234 times greater than the average of the other tested fuel elements in the reactor.
Kurzfassung
In dieser Studie wurde mit dem Ziel eines komplementären Tests der Reaktor Brennelemente am Çekmece-Zentrum für Nuklearforschung (ÇNRTC) ein Sipping-Test durchgeführt. Ein Experimentiermechanismus wurde konstruiert und im Reaktorbecken aufgebaut. Die Anordnung ermittelt undichte Brennelemente durch Sammeln und Messen von 137Cs, das aus defekten Brennelementen entweicht. Von den 31 Brennelementen, die sich im Reaktor befinden, wurde nur beim Brennelement S-104 eine 137Cs Aktivität von 10247 Bq/(0,3 l) festgestellt. Dieser Wert ist ca. 234-mal größer als die Durchschnittswerte bei den anderen getesteten Brennelementen.
