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.

A scaling factor for the neutronics parameters of the first wall was derived as a function of the plasma and first wall radii of fusion devices based on the simple albedo concept. The derived equation followed very well the scaling behavior of the heating rate and DPA obtained by ANISN as the device size was changed. The helium and hydrogen production rates were scaled with the rate φuncol/Juncol. A simple expression for the azimuthal distribution of neutronics parameters in the first wall was derived. The applicability of the expression was verified by comparing the heating rate profiles given by the equation with those by Monte Carlo calculations in the first two different shapes.
