NRC nominee Nieh commits to independent safety mission
During a Senate Environment and Public Works Committee hearing today, Ho Nieh, President Donald Trump’s nominee to serve as a commissioner at the Nuclear Regulatory Commission, was urged to maintain the agency’s independence regardless of political pressure from the Trump administration.

The Heavy Ion Fusion Virtual National Laboratory (HIF-VNL) recently initiated an effort to reach an updated, self-consistent, integrated point design for a thick-liquid inertial fusion energy power plant. We call this design the Robust Point Design. As part of this effort, the shielding design of the final focusing system has been evaluated, in an iterative fashion, with other elements of the design. The present work reports on the status of the shielding design from the perspectives of superconductor/insulator radiation lifetimes, recirculating power needed to counter nuclear heating, and neutron activation, which affects both system maintainability and waste management. Models used herein include the last three focusing magnets, and a full, three-dimensional model for the target chamber. Analyses have been performed for 9-by-9 beam arrays, with a total of 120 beams (60 per side). Results and directions for future work are presented.
