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 hydraulic results of a series of 21-rod bundle water experiments have been analyzed systematically. Models are established for the prediction of the pressure drop over unblocked bundles, grid spacers, coplanar concentric blockage, coplanar concentric blockage with bypass, noncoplanar concentric blockage, and noncoplanar nonconcentric blockage. The models can be extended to other bundles with similar characteristics. The comparisons of these models with the experimental results agree reasonably well.
