Reaktorkälte

Reaktorkälte, a term originating from German, translates to "reactor cooling" and refers to the critical process of removing heat generated by nuclear reactors. This heat is a byproduct of nuclear fission and must be continuously managed to prevent the reactor core from overheating and potentially causing damage. Effective reactor cooling is paramount for safe and stable operation of any nuclear power plant.

The primary function of the cooling system is to absorb the thermal energy produced in the reactor core and transfer it away. This heat is typically used to produce steam, which then drives turbines to generate electricity. Various coolants can be employed, with water being the most common. Other coolants include heavy water, gases like helium or carbon dioxide, and liquid metals such as sodium.

The cooling system is designed with multiple levels of redundancy to ensure continuous operation even in the event of component failure. This often involves primary and secondary cooling loops. The primary loop circulates coolant directly through the reactor core, while the secondary loop uses the heat from the primary loop to generate steam. Heat exchangers play a crucial role in transferring heat between these loops. In emergency situations, auxiliary cooling systems are activated to maintain safe temperatures. The reliable performance of the Reaktorkälte system is a cornerstone of nuclear safety.
