Reactivity is directly related to the tendency of the Rossi reactor core to change power level: if reactivity is positive, the power level tends to increase; if it is negative, the power tends to decrease; if it is zero, the power tends to remain stable. The reactivity of the reactor may be adjusted by the reactor control system in order to obtain a desired power level change (or to keep the same power level). It can be compared to the reaction of an automobile as conditions around it change (for instance, wind intensity and direction or road slope), and therefore the corresponding counter-measure that the driver applies to maintain road speed or execute a desired maneuver.
In the Rossi reactor, the control system controls the temperature at or very near the center of catalytic activity. IMHO, it is at or near the internal heater. The internal heater produces an “active agent” via the secret catalyst that travels or drifts to the reactor wall where it interacts with the nickel powder to produce heat. However, heat is produced on the wall of the reaction chamber. This wall is offset and somewhat insolated from the internal heater by a volume of high pressure hydrogen. If heat from the reaction vessel gets high enough, a runaway positive feedback loop is reacted between the wall and the secret catalyst near the internal heater. Heat travels through the high pressure hydrogen and over stimulates the secret catalyst to a state of over activity. A meltdown then occurs. As a design change to the Rossi reactor, I would suggest a heat removal system for the high pressure hydrogen to cool it during a thermal runaway condition. A heat exchanger (heat pipe) that takes heat away from the high pressure hydrogen might work. It should be thermostatically controlled via the control box to impose a maximum high temperature on the hydrogen gas. Right now heat is removed from the wall of the reaction vessel only. If heat could also be removed from the hydrogen, Rossi’s heat control problems would be solved. Some new designs of nuclear reactors use this type of passive thermal diode to control and remove the delayed heat from liquid metal or molten salt coolant after reactor shutdown.
