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.

JET and TCV data for the correlations between ELM frequency and plasma characteristics are analyzed in the framework of classical Fokker-Planck approach. A general formula is obeyed in wide range of ELM sizes with varying coefficients corresponding to the main engineering parameters. The values of the coefficients differ from those in the solution of Fokker-Planck equation for diffusion revealing the impact of non-diffusive transport. Preliminary estimations for the impact of plasma recycling and impurities on the quasi equilibrium state of pedestal plasma during ELM discharges are made. They will be verified with PIC simulation of the transport of plasma in the SOL and its interactions with the plates of the divertor.
