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.

An upgrade of the MAGFIRE code used to model the vapor shield (VS) effect was needed to include: higher disruption heat fluxes of interest to ITER, a comparison of carbon to beryllium erosion depths and the effects of ion/electron beam charge separation in the VS. Results show that higher heat fluxes give a lower total energy transmission factor (f) as expected. Beryllium divertor plates have much higher erosion depths than do carbon as well as a higher f. Charge separation has a small effect on the VS stopping power for electrons and on the distribution of deposited energy in the VS. However, the effect will be more important as the disruption particle energy increases.
