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.

Fully 3-dimensional model for Monte-Carlo simulation code (DEGAS) was newly applied in the GAMMA 10 central cell. Based on the measurement and DEGAS simulation, neutral transport during the gas puffing and neutral beam injection (NBI) in the central cell is investigated. The predicted H profile using DEGAS well explained the experimental result. It is clarified that the localized neutral source has much influence on the behavior of neutral particles in the plasma. In this paper, detailed discussion is shown from the view point of both the experiment and the simulation.
