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 study was conducted to establish the suitability of the gamma attenuation method for measuring void fractions in a parallel rod array. A lucite mock-up was used to evaluate the accuracy of the method; the error was found to vary from 7 to 13% depending upon the measuring method. Data were taken on an air-water system flowing vertically upward at atmospheric pressure, and were found to agree reasonably well with similar data for rectangular channels and round tubes. The results of this study are being used to guide the execution of the 600 psia boiling water, void experiments which are part of the heat transfer development for the Pathfinder Boiling Water-Integral Superheating Reactor.
