Deep Space: The new frontier of radiation controls
In commercial nuclear power, there has always been a deliberate tension between the regulator and the utility owner. The regulator fundamentally exists to protect the worker, and the utility, to make a profit. It is a win-win balance.
From the U.S. nuclear industry has emerged a brilliantly successful occupational nuclear safety record—largely the result of an ALARA (as low as reasonably achievable) process that has driven exposure rates down to what only a decade ago would have been considered unthinkable. In the U.S. nuclear industry, the system has accomplished an excellent, nearly seamless process that succeeds to the benefit of both employee and utility owner.

In this overview, the main arguments for a kinetic description of a classical non-relativistic many particle system are reviewed. First, the need and strategy for a kinetic description of plasma particles is discussed. The Vlasov, the Landau-Fokker-Planck, and the Balescu-Lenard equations are presented as the most useful kinetic equations for the particle distribution functions. It is shown that a linearization of the initial value problem can already give interesting insights into the dynamic behaviors. In many cases a reduction to a plasmadynamic (fluid) description is appropriate, and popular truncations are summarized. Finally, the basic methods for a kinetic description of waves are presented. When some wave excitations are driven unstable and the collective motion of particles dominates, the wave-kinetic equations will be the appropriate dynamical equations. It is shown that spectra of the Kolmogorov-Obukhov type are exact stationary solutions of the latter.
