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.

Steady state as well as transient hydrogen permeation models have been calculated. Especially a complex pressure dependence for bright as well as oxidized alloys could be derived and compared with the various experimental findings confirming the observed transitions between square root and linear pressure dependence in the different pressure ranges. A diffusion limited transport model with linear boundary conditions has been used to describe time dependent permeation. Thereby the oxide has been treated as a heterogeneous two phase system, where the “good” phase mainly determines its effectiveness in permeation reduction which is more or less lessened by the “bad” phase.
