Division Spotlight
Nuclear Installations Safety
Devoted specifically to the safety of nuclear installations and the health and safety of the public, this division seeks a better understanding of the role of safety in the design, construction and operation of nuclear installation facilities. The division also promotes engineering and scientific technology advancement associated with the safety of such facilities.

Senate committee advances NRC nominee Matthew Marzano
Marzano
The U.S. Senate Environment and Public Works Committee voted 10–9 last week to advance the nomination of Matthew Marzano to serve on the Nuclear Regulatory Commission. It was a party-line vote, with all Democrats supporting Marzano and all Republicans voting “no.”
Marzano was nominated by President Biden in July to fill the open NRC seat, and the EPW Committee held a hearing in September on his nomination. His nomination will now go to the Senate for a vote, but it is not certain whether that will happen before the end of the year, in which case his nomination process would start over in 2025.
The five-member commission has been without a tiebreaker vote since June 2023 when Jeff Baran’s term expired.

Radial profiles of the rotational transform are measured with the motional Stark effect spectroscopy in the Large Helical Device. They are derived from the radial profiles of the polarization angle of the and components in the H line emitted from high-energy hydrogen atoms of beams with four sets of linear polarizers, spectrometers, and charge-coupled device detectors. Changes in the rotational transform due to the neutral beam current drive (NBCD) and the electron cyclotron current drive are measured. When NBCD is in the direction counter to the equivalent plasma current, the central rotational transform increases because of the inductive current while the edge rotational transform decreases, as is expected. Therefore, the magnetic shear becomes weak with NBCD in the counterdirection, whereas it becomes strong with NBCD in the codirection. NBCD that drives toroidal current, typically <10% of the equivalent toroidal current determined by the external current in the helical coils, can change the rotational transform and magnetic shear significantly enough to change magnetohydrodynamic stability.
