Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Phébus FP tests study the phenomenology of severe accidents in water-cooled nuclear reactors. The first test, FPT0, was performed with fuel irradiated for only 1 week; the second test, FPT1, was performed with fairly similar boundary conditions but with irradiated fuel (burnup: 23 GWd/t). The objective of this work is, on the one hand, to summarize the main experimental results of these two tests concerning the behavior and transport of fission products and structural materials in the circuit and, on the other hand, to identify or to confirm any modeling weaknesses in the SOPHAEROS/ASTEC V1 module used for interpreting the experimental results. Besides comparison with available experimental data, the main results of the entire circuit analyses are compared with former SOPHAEROS/ASTEC V0 analyses and, for so-called quasi-separated steam generator tubes, with one- and two-dimensional Eulerian and Lagrangian (particle tracking) models.Concerning the transport of iodine vapor species, it is shown that the results obtained are compatible with passage of nonnegligible amounts of the measured highly volatile iodine through circuit to containment. It is also shown that these results depend heavily on the considered kinetics of Cd release from the bundle.
