I hate to tell you, but I am working on fuel rods that are made from something other than zirconium so there is no production of hydrogen possible.
If successful, then it is a “cheap fix” and will put molten salt on the back burner.
Secondly, the problem at Fukushima was the lack of power to the circulating pumps. Today, every nuclear plant in the US is “hardening” their systems with backup generators/pumps in safe buildings away from the plant that can be hooked up quickly to restore power.
Fukushima exposed a flaw in the safety of nuclear power plants. But it is a flaw that is easily fixed without new reactors (that may bring their own new set of issues with them).

Fukushima’s flaw was the diesel tanks that provided fuel for the generators were located outside the buildings walls. When the flood came it washed away the tanks. Basic design flaw. A protection wall around the tanks would have prevented the entire episode at that facility.
Not putting the spent fuel pond on top of the reactor would help too.
