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.

A favorable distribution of fuel temperature in block-fuel HTGRs can be achieved by an axial shift in the power density toward the cooling gas inlet. This is of particular importance for advanced reactor applications requiring gas outlet temperatures above 900°C. The concept of axially graded heavy-metal densities and fuel enrichment allows for achieving and maintaining the desired asymmetrical power profile through the entire period of fuel insertion.
