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.

Embrittlement of Zircaloy fuel cladding tubes by corrosion media was studied from the viewpoint of its applicability to spent-fuel reprocessing. The results from irradiated as well as unirradiated tubes are summarized as follows: 1.When iodine was employed as the solute, the use of methanol as the solvent caused significant embrittlement of the Zircaloy. 2.For the iodine-methanol solution, the embrittlement increased with the iodine content but saturated at 1 wt%. 3.A water content of up to 10 vol% in the iodine-methanol solution did not decrease the extent of embrittlement. 4.Fracture was of the grain-boundary type, and a fuel cladding tube irradiated to ∼35 GWd/t showed the same embrittlement behavior as an unirradiated one.
