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.

Since the initiation of fuel irradiations in the Vallecitos Boiling Water Reactor in 1957, rod-type fuel elements have been irradiated in an increasing number of boiling-water reactors. The most extensive experience has been obtained with Zirealoy-2 clad, UO2 pellet-type fuel rods. Somewhat less experience has been obtained with other fuel forms such as ThO2 -UO2 pellets and UO2 compacted powder and with other clad materials such as Zircaloy-4, Type 304 stainless steel, Incoloy-800, and Inconel-600. Based on the highly successful performance of many thousands of fuel segments operating at typical commercial power-reactor thermal ratings, UO2 rods clad with Zircaloy-2 have proven to be the most reliable and economical fuel elements for boiling-water reactor applications.
