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 analysis of two-dimensional fluid flow and heat transfer problems in a finite rod bundle system can be effectively handled by superpositioning the effects of all cylindrical rods present. This method is not limited to symmetrical rod arrangements but can be applied to rods with arbitrary dimensions and orientations. The solution method is illustrated by solving the Poisson and the Helmholtz equations. Numerical results are presented for the solution of the Helmholtz equation in a circular flow channel containing a center rod and a ring with six peripheral rods and with Dirichlet boundary conditions specified on the wall surfaces.
