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.

The modeling steps needed to create dynamically based automated control of tokamak plasmas are traced. This involves integrating models of current/magnetic-flux dynamics; plasma transport; plasma geometry; and source terms, such as lower hybrid, fast wave, and pellet-fueling deposition. Perturbative analysis of these models then yields the linear response of the tokamak to changes in coil voltages, applied radio-frequency power, or pellet-firing frequency. Comparison of the linear response models to nonlinear numerical calculations reveals that the plasma position and shape modeling will require future refinements.
