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 class of partial differential equations is considered that is directly connected with the transport equation. It is shown that if the initial-boundary conditions are specified on a given net as univariate quadratic splines, then there exists a bivariate quadratic spline unique on the net that satisfies exactly the initial boundary conditions and satisfies the differential equation at the nodes of the net. The spline is then constructed by an exact finite-difference scheme. As a first application we provide a new algorithm for a spherically symmetric problem in neutron transport theory. This is further illustrated by numerical examples.
