Uneven x-ray absorption can disturb ICF implosion symmetry; a dense propellant region smooths the pushing profile and energy transfer.
A concavo-convex reinforcing plate stiffens the steam dryer hood against external pressure without thickening the hood plate.
Segmented upper and lower supports free space above the core for heat exchangers while constraining fuel elements axially and radially.
Natural circulation and borated-water injection simplify LPWR safety systems while reducing construction and maintenance costs.
Integrated depressurization and water-gas sampling detect fission products in nuclear fuel assemblies without costly penetrant cells.
Sample-air radiation sensing and shielding help identify small reactor coolant leaks despite high background radiation.
