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 source range monitor (SRM) response during the first 25 h of the Three Mile Island Unit 2 (TMI-2) accident is analyzed. The response of the SRM was simulated by performing static neutron transport calculations on a variety of lower head core material distribution models. Using the previously derived core and lower head material configurations at 225 min and 3 yr after shutdown as starting points, the changing lower head material distribution during the period from 225 min to 25 h after shutdown was estimated. The estimated lower head material distribution derived from this transport analysis appears to be consistent with other studies performed under the auspices of the TMI-2 accident evaluation program.
