Abstract
Source term research has continued internationally for
more than 30 years, increasing confidence incalculations
of the potential radioactive release to the environment
after a severe reactor accident. Important experimental
data have been obtained, mainly under international
frameworks such as OECD/NEA and EURATOM. Specifically,
Phébus FP provides major insights into fission product
release and transport. Results are included in severe
accident analysis codes. Data from international projects
are being interpreted with a view to further improvements
in these codes. This paper synthesizes the recent main
outcomes from source term research on these topics, and
on source term mitigation. It highlights knowledge gaps
remaining and discusses ways to proceed. Aside from this
further knowledge-driven research, there is consensus on
the need to assess the source term predictive ability of
current system codes, taking account of scale-up from
experiment to reactor conditions.
