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 method for joining Zircaloy-2 with stainless steel, using controlled expansion transition sections, is described. The transition sections consist of nickel-iron elements of the Invar type and range from low expansion rate 43% nickel-iron, at the Zircaloy-2 end, to high expansion rate 60% nickel-iron, at the stainless steel end. Problems encountered in producing suitable mechanical joints between Zircaloy-2 and 43 % nickel-iron and in preparing and welding the various grades of nickel-iron to each other and to stainless steel are discussed.
