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.

These lecture notes provide a short overview of classical and neoclassical transport in tokamaks. The classical theory is widely applicable in laboratory and space plasma physics if the mean free path is shorter than the macroscopic scale length. The neoclassical theory predicts important phenomena in tokamaks such as the bootstrap current, electric conductivity, transport in the scrape-off layer, and cross-field transport in regions where the turbulence is suppressed.
