Irradiation Experiment BR2-P18 - Follow-up program
Description
Automatic translation: The radiation experiment BR2-P18 is expected to be in May 1977 be terminated. At this point there will be a fluence of fast neutrons of about 9 x 1021 cm-2, E> 0.1 MeV and a burn-up of about 74% Fima can be achieved. Up to a fluence of fast neutrons of 5.5 x 10 2 1 cm - 2, E> 0.1 MeV (300 EFPD), the cracked gas release was around R / B = 10-6 for the Krypton isotopes 88 and 85 m. Thereafter, a continuous increase was made R / B ~ 10-4 observed at year-end. The follow-up examination should clarify which types of particles have failed with what proportion and how Damage mechanism looks like. The results are related to BR2-P19 are evaluated.
Abstract (German)
Das Bestrahlungsexperiment BR2-P18 wird voraussichtlich im Mai 1977 beendet werden. Zu diesem Zeitpunkt werden eine Fluenz schneller Neutronen von etwa 9 x 1021 cm-2 , E>0,1 MeV und ein Abbrand von etwa 74 % Fima erreicht sein. Bis zu einer Fluenz schneller Neutronen von 5,5 x 1021 cm-2, E > 0,1 MeV (300 EFPD) lag die Spaltgasfreisetzung um R/B = 10-6 für die Krypton-Isotope 88 und 85 m. Danach wurde ein kontinuierlicher Anstieg auf R/B ~ 10-4 am Jahresende beobachtet. In der Nachuntersuchung soll geklärt werden, welche Partikelsorten mit welchem Anteil versagt haben und wie der Schadensmechanismus aussieht. Die Ergebnisse werden im Zusammenhang mit BR2-P19 ausgewertet werden.Files
