Heating demand will decrease

One of the principal design goals for the SSR is to provides power on an as-needed basis and shut down automatically when there is no demand. This is accomplished by designing the reactor to have a negative temperature coefficient. As the heat extraction is decreased (power demand is reduced), the reactor temperature will increase causing an increase in parasitic neutron absorption in the fuel due to the Doppler effect. The power level of the reactor will then drop to the level where the thermal heat production balances the thermal heat removal.
