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.

Consistent calculation and analysis of neutron scattering data of 233,235,237U with optical model, semiclassical model including both the unified Hauser-Feshbach theory and the exciton model, the coupled channel theory, and distorted wave Born approximation were carried out in the En 20-MeV energy range based on the experimental data. In particular, the analysis includes the prompt fission neutron spectra and the double-differential cross section for neutron emission. Theoretical calculations are compared with recent experimental data and other evaluated data from ENDF/B-VI release 6 and JENDL-3.3.
