Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Nuclear metallic fuels are one of many options for advanced nuclear fuel cycles because they
provide dimensional stability, mechanical integrity, thermal efficiency, and irradiation resistance
while the associated pyro-processing is technically relevant to concerns about proliferation and
diversion of special nuclear materials. In this presentation we will discuss recent success that we
have had in studying isochronal annealing of damage cascades in Pu and Pu(Ga) arising from the
self-decay of Pu as well as the annealing characteristics of non-interacting point defect
populations produced by ion accelerator irradiation. Comparisons of the annealing properties of
these two populations of defects arising from very different source terms are enlightening and
point to complex defect and mass transport properties in the plutonium specimens which we are
only now starting to understand as a result of many follow-on studies. More importantly
however, the success of these measurements points the way to obtaining important mass
transport parameters for comparison with theoretical predictions or to use directly in existing and
future materials modelling of radiation effects in nuclear metallic fuels. The way forward on
such measurements and the requisite theory and modelling will be discussed.
We bring to the attention of the reader that this article is based wholly or in part on earlier
publications of the authors. |
