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.

Rate coefficients and normalized differential scattering rate distributions for (n-n), (n-d), (n-t), and (n-6Li) elastic reactions for radially translating Maxwellian-distributed targets are examined for energy and temperature ranges related to fusion energies. For these reactions, both asymptotically constant cross sections and cross sections decaying inversely as the relative speed are treated. For the (n-d), (n,t), and (n-6Li) cases, actual multigroup cross sections are employed in the energy range from 0 to 17 MeV, while the (n-n) interaction is treated in the hard sphere limit. Some results for various incident and final neutron energies at a target temperature of 2 MeV are listed, and conclusions from an extensive numerical analysis are given.
