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 convergence properties of the discontinuous Galerkin finite element method (DGFEM) applied to the transport equation are presented for variants of Larsen's test case. The analysis is performed for two-dimensional structured and unstructured triangular meshes, with DGFEM approximations up to order 4. Pure absorber media and scattering media are considered. The influence of the mesh alignment with the singularities of the transport solution is described. The numerically observed convergence rates are related to theoretical results.
