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 this paper we analyze the decay of a neutron pulse in small nonmultiplying systems, through the use of a simple model for the moderator. The model, a modified one-term degenerate kernel, enables us to include crystal-effects, and, at the same time, to reduce Boltzmann's equation to quadratures. We discuss the structure of the continuum contribution, and the analytic continuation of the functions λk(B2) Our analysis should elucidate some of the puzzling aspects of pulsed-neutron experiments in crystalline moderators, and the multigroup calculations which accompany them.
