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.

Reactor noise techniques have been used to determine how the quantity Beff/I changes when water regions of several sizes and shapes are introduced into a light water lattice of plutonium-enriched rods. The measured value of Beff/l for the unperturbed uniform lattice was 89 ± 2 sec−1. This value was reduced significantly as successively larger water regions were introduced into this lattice. Calculated values of Beff/l obtained with a typical reactor design calculational method, agree with measured results to within ±5% for these experiments.
