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.

The discrete gamma radiation in the interaction of 14.9-MeV neutrons and a natural copper sample is investigated with the total gamma radiation measurement technique. One hundred seven prompt gamma rays, which come mainly from the reactions (n,n'), (n,2n), (n,np), (n,d), (n,p) and (n,) of 63Cu and 65Cu, are identified by a high-resolution gamma-ray analysis code. According to the systematic knowledge of 14.9-MeV neutron-induced 63,65Cu(n,x) reactions, nine final nuclei are identified, and 139 possible transitions are designated. The differential elemental production cross sections of 107 gamma lines at 90 deg and 79 gamma lines at 55 deg are determined. The nine integral isotopic cross sections of 11 reaction channels including 63Cu(n,n')63Cu, 63Cu(n,2n)62Cu, 63Cu[(n,np) + (n,d)]62Ni, 63Cu(n,p)63Ni, 63Cu(n,)60Co, 65Cu(n,n')65Cu, 65Cu(n,2n)64Cu, 65Cu[(n,np) + (n,d)]64Ni, and 65Cu(n,p)65Ni are also obtained. The present results are in good agreement with some recent experimental and evaluated results.
