Fission product distribution and release in the high-temperature irradiation experiment JK 3

Creators

Description

Automatic translation: The JK 3 irradiation experiment involved the testing of five pressed fuel element spheres at high power (7 to 8 kW/sphere) and high fuel temperature (1400 to 1500°C). 1500°C). Immediately after the start of irradiation, the planned temperatures were considerably exceeded and average values of 1700 to 1900°C were reached /1/. Very high fission gas releases were measured were measured. This led to the premature termination of the irradiation after 37 days.

Abstract (German)

Das Bestrahlungsexperiment JK 3 Hatte die Erprobung von fünf gepreßten Brennelementkugeln bei hoher Leistung (7 bis 8 kW/Kugel) und hoher Brennstofftemperatur (1400 bis 1500°C) zum Ziel. Gleich nach Beginn der Bestrahlung wurden die geplanten Temperaturen erheblich überschritten und mittlere Werte von 1700 bis 1900°C erreicht /1/. Dabei wurden sehr hohe Spaltgasfreisetzungen gemessen. Das führte zum vorzeitigen Abbruch der Bestrahlung nach 37 Tagen.
