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 SIRENS high heat flux facility at NCSU has been used to generate particulate representative of material mobilized during a hard disruption in a fusion reactor. The electrothermal (ET) plasma source in SIRENS has been found to be suitable for disruption simulation. Particulate generation occurs in both the fusion reactor and the ET source as material mobilized from the plasma-surface interface expands into a large volume. The response of carbon-based material and carbon/metal mixtures to disruption simulation in SIRENS has been studied and the resulting particle size data are presented in this paper. Specific materials investigated include Lexan polycarbonate, graphite grades UTR-22 and ATJ, and combinations of Lexan with each copper, stainless steel 316, tungsten, and aluminum.
