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.

The study of hydrogen diffusion parameters in austenitic steels EP-838, Cr12Mn20W, 316 SS, 12Cr18Ni10Ti was carried out. Temperature dependences of permeability, diffusion coefficients and hydrogen dissolution were determined and their variation with the phase and structure composition of the steel were analyzed. It is shown that change of alloy composition, thermal treatment in hydrogen and modification of surface by nitriding, oxidizing and by irradiation with H+ and N+ ions can lead to a decrease in hydrogen permeability and thus reduce hydrogen isotope losses through the thermonuclear reactor first wall.
