Commercial fusion developers are transitioning from theoretical physics models to physical component testing. The integration of high-temperature superconducting (HTS) tape allows for stronger magnetic fields in smaller reactor volumes.
Magnetic Field Density Milestones
Recent test facilities achieved sustained magnetic field strengths exceeding 20 Tesla. This increase in field density significantly reduces the required size of tokamak devices, driving down projected capital expenditure per megawatt of capacity.
Neutron Shielding Materials Needed
The focus has now shifted to material science challenges regarding reactor wall durability. Engineering teams are testing advanced tungsten alloys and liquid metal blankets to withstand intense neutron bombardment over extended operational cycles.
