<p class="MsoNormal">The completion of the National
Ignition Facility (NIF) marks a new era in the effort to generate energy
through controlled nuclear fusion. NIF utilizes the indirect drive approach to
inertial confinement fusion (ICF), producing radiation within a hohlraum to
compress capsules to densities and temperatures sufficient for sustained
thermonuclear reactions. Current experiments on NIF are aimed at achieving
ignition within the next few years. These experiments also depend upon (and
validate) our understanding of and capability to simulate multiple interacting
physical processes. These processes include hydrodynamics, radiation transport,
plasma physics and atomic physics, as well as the desired nuclear reactions.
Non-Local Thermodynamic Equilibrium (NLTE) refers to an approach to treating
the interaction of atoms, electrons and radiation within a plasma which relaxes
the usual assumption that the matter is in thermal equilibrium. Changes in the
treatment of this physics can dramatically affect the energy balance within the
hohlraum and the capsule performance, emphasizing the need for an accurate
treatment of this computationally intensive topic. <o:p></o:p></p>
