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 relation between the radial potential profile of the core plasma are examined in the tandem mirror GAMMA 10. It is observed that the radial potential profiles are convex over the cross section of the plasma column and the high energy end-loss ions over the confinement potential are decreased too in many shots. The radial potential profiles were controlled by changing the electrostatic potential profiles of the separated coaxial end plates. On flattening the radial profiles, the reduction of the high energy end-loss ions was softened and the plasma density increased in the central cell. These results suggest that the flattened radial potential profiles decrease the radial diffusion and improve the confinement of the plasma.
