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.

Disruptions lead to the largest operational electromechanical loads on the vessel, its supports, and the in-vessel components. In addition, plasma-facing components can be exposed to very high thermal fluxes during the plasma thermal quench and to high-energy runaway electron beams. Therefore, disruptions represent one of the most demanding design load cases for this and the next generation of tokamaks, and they will need to be always strongly ameliorated or totally avoided in a commercial power plant. An overview of the observations and of the analytical and experimental work on disruptions carried out at JET both during the Joint Undertaking and under the European Fusion Development Agreement is presented.
