As part of a programme investigating fission gas release, (U,Pu)O(2) minipins irradiated to 1-2 at% burn-up underwent a rapid power ramp (approximately 10 msec) in a pressure cell under argon in the Silène reactor. The pins were open-ended to accommodate any fuel expansion. After the ramp, the volume of gas released was measured and analysed by mass spectroscopy. TP29 and TP36 were ramped at approximately 1400 J/g to reach the fuel's melting point. TP29 had a high fill gas pressure of 3.7 bar Ar (6.78 bar during ramp), whereas TP36 had a low pressure of 0.2 bar Ar (1.37 bar during ramp).
