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.

A simplified but approximate method for the calculation of nuclear heating is described. Results using this method are compared with those of more rigorous calculations. The computational effort required is significantly reduced, and an accuracy generally better than ±20% can be achieved provided reasonable estimates of gamma-ray production are used. It would appear that the gamma-ray absorption coefficients used here are too low as a result of assuming average gamma-ray energies that are too high. As experience is gained with use of the method, greater accuracy should result from improved assumptions regarding both gamma-ray production and average gamma-ray energies.
