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.

In the design of power reactors containing lattices of fuel rods in liquid coolant, it would be useful to employ cell-averaged transport parameters reflecting anisotropic neutron migration when this is significant. Measurements and Monte Carlo calculations of anisotropic neutron migration are described for rod lattices. The well-known flux peaking near thin sources is found to be accompanied by thin source effects on migration areas. Situations of substantial migration anisotropy and thin source effects are delimited.
