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.

Twenty-four-hour sweep tests have been carried out in flowing air at 200 and 400°C on deliberately defected UO2 fuel elements with 2.5-yr discharge times. At 200 C there was no diametral change, but at 400 °C, swelling and severe sheath cracking were observed. Neither short-lived fission products nor 134Cs, I37Cs, or 106Ru were detected above background. Maximum 85Kr release was ≤7.4 × 104 Bq (≤2 × 10-6 Ci).
