Abstract:Fission gas extraction and analysis has been carried out on fuel pins of fast breeder test reactor subassemblies at different burn‐ups as a part of post‐irradiation examinations to characterise the performance of the unique mixed carbide fuel and estimate the residual life. This paper describes in detail the fission gas extraction and analysis carried out on fuel pins after various stages of burn‐ups of 25, 50 and 100 GWd/t. The analysis of fission gas was carried out by gas chromatography. Analysis indicated that the maximum percentage of gas release is 14% after a burn‐up of 100 GWd/t, and the corresponding plenum pressure is 1.2 MPa.
