The reactor must be designed such that temperature can be precisely controlled and the reaction shut down if temperature control is lost. The use of solvents or inert species also allows for temperature control by adjusting heat capacity flow rate relative to rate of heat release from the reaction.

Nuclear reactor - Coolant system | Britannica

Nuclear reactor - Nuclear reactor - Coolant system: The function of a power reactor installation is to extract as much heat of nuclear fission as possible and convert it to useful power, generally electricity. The coolant system plays a pivotal role in performing this function. A coolant fluid enters the core at low temperature and exits at a higher temperature after collecting the fission energy.

How Does Temperature Affect the Rate of Reaction? | Sciencing

How Does Temperature Affect the Rate of Reaction? | Sciencing

The effect of temperature on rate of reaction is just one of the things that can affect how a reaction proceeds, that is, how quickly whatever reactants are present become transformed into products. Of course, many of these factors are active at all times and can have competing influences on the overall rate of a given reaction.
