Often both heating and cooling are required. Split ranged control is used to go back and forth between heating and cooling. In split range control for an exothermic reactor with a fail open cooling valve, as the temperature controller output increases from 0% to the split range point, the coolant valve goes from wide open to completely closed.
Reversible Heat Pumps. Reversible heat pumps work in either direction to provide heating or air conditioning (cooling) to the internal space. They employ a reversing valve to reverse the flow of refrigerant from the compressor through the condenser and evaporation coils.. Heating and Air Conditioning. In heating mode, heat pumps are three to four times more effective at heating (i.e. .
Jacketed Reactor Heating & Cooling. In reactors, heating and cooling jackets are used to remove heat from exothermic reactions or provide the needed heat required to produce the desired endothermic reactions. Steam jackets that operate at high pressures can pose safety issues, especially when hazardous chemicals are being used within the reactor.

There is usually no conflict in a batch reactor control system between PID settings for heating and cooling, because heating only brings the primary temperature up to set point, where cooling takes over. Therefore the cascade system should be tuned for cooling, and this usually gives acceptable results for heating.

Reactor Cooling in Power Operation. Nuclear power plants rely on cooling systems to ensure safe, continuous operation of the nuclear reactor. Cooling systems naturally ensure a heat transfer from a reactor core to steam generators, which is the main purpose of the cooling systems.Because of the large amount of heat generated in the reactor core by the fission reaction, the cooling systems .
It appears that this is a dual control problem with heat required at one stage, and cooling required after the reaction begins, but I don't see the two controllers that would be required. It also appears that the reactor jacket does not supply enough cooling/heating since there is a separate circulation stream for heating and cooling.
