“…It is likely that the lagging behavior, compared to silver and cesium, is a result of a slower diffusion of strontium out of particles with failed SiC and the already discussed holdup that would occur in the matrix graphite and surrounding graphite holder. There could also be some impact from a higher stability of strontium in the UO2 kernel, where it is expected to reside as an oxide [McMurray et al 2017].…”

Revision Date Affected Pages Revision Description 0 All Initial issue * The background text in this introduction section originally appeared in a previous AGR-2 PIE report [Hunn et al. 2016a].† In this report, the term "fission product" is used in a general sense to refer to all the post-fission isotopes remaining at the end of the irradiation test. These include: isotopes directly generated by the fission process, isotopes generated by neutron capture, isotopes generated by radioactive decay, and residual uranium.

“…These results have been used to determine minimum carbide contents for given target burnups. A paper detailing this work has been published in Annals of Nuclear Energy (McMurray et al 2017). These results will be combined with kernel-to-kernel phase distribution data to determine mean and minimum carbide phase fractions for an eventual X-energy fuel specification.…”
