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 study of the spectral radius for the continuous form of the source iteration, diffusion synthetic acceleration, and various PL acceleration methods (L ≥ 1) for anisotropically scattering neutron transport is carried out via a Fourier stability analysis. The purpose of the study is to determine which acceleration scheme is optimum. The problem is formulated as a matrix eigenvalue problem with, in general, N + 1 iteration eigenvalues ω where N denotes the degree of anisotropy. The P1 acceleration method is determined as the most efficient PL approach for the cases of linearly and quadratically anisotropic scattering.
