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 GAMMA 10, plasma was generated and heated by conventional ICRF systems (RF1, RF2). RF3 system with the 10th harmonic ion cyclotron frequency near the midplane of the central cell was applied for the high-density plasma generation. At the same time, a plasma heating by RF3 was observed. Wave damping was calculated by using the hot plasma distribution in infinite and homogeneous plasma. It is clearly seen the high-energy component is important for the damping of high harmonic fast waves. The experimental observations in GAMMA 10 suggest the existence of high-energy tail in the energy distribution of ions.
