In a system that uses only temperature as a control mechanism(Rossi), what the hydrogen system needs is negative feedback in the hydrogen system to counteract reactor meltdown. This might be provided through the use of a small internally sealed hydrogen storage tank controlled with a smart valve that opens when the temperature starts climbing above the maximum operating temperature of the reactor and releases hydrogen as the operating temperature cools.
When the reactors' operating temperature cools, the tank would release the sequestered hydrogen back for hydride storage. What would be ideal is a mix of different types of hydride that did this balancing of hydrogen through temperature control using chemistry only.
