An analysis of the thermal and structure behaviour of the UO2-PuO2 fuel in the irradiation experiment FR2 capsule test series 5a

Description

In the Karlsruhe research reactor FR2 nine fuel pins were irradiated within three irradiation capsules in the course of the test series 5a. The pins contained UO2-PuO2 fuel pellets. They reached burnup values of about 6,17 and 47 MWd/KgMe with linear rod powers of 400 to 600 W/cm and clad surface temperature between 500 and 700 deg C. A detailed analysis of the fuel structuration data (columnar-grain and equiaxed-grain growth regions) have allowed to determine, with the help of physic-mathematical models, the radii of these regions and the heat transfer through the contact zone between fuel and clad depending on the burnup. The results of the analysis showed that the fuel surface temperature rose with increasing burnup. (author)
