Benchmark analyses on fission product gas bubble behavior in liquid sodium coolant
Keywords:Fission Product, Transport Phenomena, Sodium, Fast Reactor, TRACER
To quantify the migration behavior of bubbles containing non-condensable gas fission products after being released from fuel pins, it is essential to develop numerical analysis code including physical, chemical, and flow models. In this report, we focus on the breakup behavior of bubbles during elevation in sodium coolant, and we report on the results of benchmark analyses on the correlation between the decontamination factor and the bubble rise velocity.
