Conditions during the release of radionuclides during the Chernobyl reactor accident
Description
An attempt is made to estimate the conditions of the release of radionuclides and fuel during the Chernobyl accident. The composition of the nuclide mixtures from many measurements was analyzed using the results of two experimental programs. Besides the release with fuel particles, radionuclides were mainly released at temperatures above 24000C. The cladding was not oxidized by steam. The behaviour of ruthenium cannot be explained satisfactorily. The reactor core was heated up over several days. During this time, more and more fuel elements were affected and destroyed. The results of the analysis do not fully agree with the descriptions given by the Soviet authorities. (orig.)
Abstract (German)
Es wird versucht, die Bedingungen waehrend er Freisetzung der Radionuklide und von Brennstoff waehrend des Reaktorunfalls von Tschernobyl abzuschaetzen. Zahlreiche Messungen wurden an Hand von zwei experimentellen Programmen analysiert. Neben der Freisetzung mit Brennstoffpartikeln wurden die meisten Spaltprodukte bei Brennstofftemperaturen oberhalb 24000C freigesetzt. Dabei war das Huellrohrmaterial nicht durch Wasserdampf oxidiert. Das Verhalten von Ruthenium kann nicht ausreichend erklaert werden. Der Reaktorkern wurde ueber Tage hinweg aufgeheizt, wobei immer neue Brennelemente betroffen waren. Die Ergebnisse der Analyse sind zum Teil in Widerspruch zu den Angaben, die von sowjetischer Seite gemacht wurden. (orig.)Additional details
