Katy Huff on the impact of loosening radiation regulations
Katy Huff, former assistant secretary of nuclear energy at the Department of Energy, recently wrote an op-ed that was published in Scientific American.
In the piece, Huff, who is an ANS member and an associate professor in the Department of Nuclear, Plasma, and Radiological Engineering at the University of Illinois–Urbana-Champaign, argues that weakening Nuclear Regulatory Commission radiation regulations without new research-based evidence will fail to speed up nuclear energy development and could have negative consequences.

Single crystal tungsten samples with orientation (110) were irradiated in the Materials Irradiation Experiment with normal incidence 30 keV He+ at 900 aC. Samples were mechanically polished and then electropolished with a KOH solution before irradiation to 3×1017 to 6×1018 He+/cm2. With increasing fluence sample surface pore size increased from ~20 nm to more than 100 nm. Mass loss also increased with fluence to a maximum of 15 g/m2 lost for the highest fluence sample.
