Revaporization of Tests on Samples from Phebus Fission products
Revaporization is probably the most significant uncertainty in the present understanding of fission product source terms, and it has the potential to change many of the parameters used to categorize source terms. A programme is underway to provide a detailed understanding of revaporization phenomena, based on separate effects studies involving inactive fission product simulants and radio tracer samples, and integral validation of these studies with analysis of samples from the Phebus-FPT-1 test. The programme involves Knudsen cell mass spectrometry and thermal gradient tube methods, as well as the use of sophisticated analytical techniques, to study both simulant and FPT-1 samples.
