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.

A complete description of a system in equilibrium is provided by the Grand Canonical Distribution. But, systems are generally not in statistical equilibrium. We shall consider the case of an ideal gaz of charged particles. The linear theory of transport determines the 3 × 1 matrix of dissipative fluxes [circumflex]Jr namely, the electric current and the electronic and ionic heat fluxes, in terms of a 3 × 1 matrix of thermodynamic forces [circumflex]X defined by the electric field and the gradient of the densities and temperatures. The components of the 3 × 3 matrix of tensors [circumflex]Lrs of the linear flux-force relations [circumflex]Jr = [summation]s=19[circumflex]Lrs[circumflex]X define the set of transport coefficients. They are evaluated for an ion-electron magnetized plasma in the framework of the statistical mechanics of charged particles starting from the Landau kinetic equation.
