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 remaining-life estimation of components is acquired in three steps: 1. Calculation of the life consumption indicates where tests on exposed material should be carried out. 2. Tests on exposed material are carried out on most exposed parts to evaluate the real creep degradation of the exposed material. 3. Continued operation is based on the results of the precalculation and the creep degradation of the material. At the next inspection the material tests will indicate whether a prolonged safe operation is possible.Material tests for remaining-life estimation are based mainly on replicas by which the creep life can be evaluated more quickly, more easily, and at lower cost than by any other method, presuming that the creep degradation starts from the outer surface of the parts. Replicas are then most effective in the time-to-failure estimation of parts, although they allow a high life exhaustion. After 6 yr of experience, not even unscheduled repair has been necessary for inspected parts.
