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.

Analyses of property changes during reirradiations and anneals show that the technique of alternate reirradiations and anneals can be used consistently to remove radiation damage from graphite. Laboratory experiments, monitoring studies and reactor-height measurements all correlate favorably. It is shown that the recovery for a reirradiation and annealing cycle is independent of irradiation temperature between 30 C and 200 C and total damage over wide ranges. The reciprocal of the recovery per cycle is a linear function of the exposure between anneals with a slope that is determined by the anneal temperature.
