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.

A model to describe an ion-electron-beam fluid equilibrium state is presented. The effect of the centrifugal force of beam ions on the plasma pressure profile is considered. From the toroidal force balance, it is possible to calculate the temperature and density for both ions and electrons. A preliminary calculation result of the plasma pressure profile in the three-fluid system is presented.
