The design of the National Ignition Facility was never intended to study commercially viable fusion power. It's exclusively a physics testing facility with origins for testing the physics of thermonuclear fusion weapons for better bomb design.

Nothing that happens at the NIF is very useful in heading towards commercially viable fusion. The design of the testing apparatus is also similarly incompatible with making a sustained fusion device as there is no way to continuously feed in fuel into the device, nor methods of extracting the energy.
