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.

With recently published results of Kaper et al. as a basis, accurate extrapolated endpoints have been calculated for homogeneous pulsed slabs and spheres. The neutrons were assumed to be monoenergetic and to scatter isotropically. In contrast to P3 calculations, the results indicate a zero slope at small bucklings of the curve describing the extrapolated endpoint as a function of buckling.
