NRC proposes security regulation changes
In 2025, President Trump issued Executive Order 14300, “‘Ordering the Reform of the Nuclear Regulatory Commission,” which directs the NRC to conduct a sweeping, multifaceted overhaul of its structure, culture, and regulations with the aim of facilitating increased deployment of new nuclear technologies and capacity.

The space between the double walls of ITER Vacuum Vessel is filled with pre-assembled or modular shield blocks called "in-wall shielding". It has two main functions; one is to provide an effective neutron shielding and the other to reduce the toroidal field ripple in the outboard region. The in-wall shielding is designed to minimize electromagnetic forces acting on the shield blocks. The electromagnetic forces have been calculated with the latest disruption scenarios. Magnetization forces have also been calculated for ferromagnetic inserts. Structural integrity has been validated by structural analyses.
