What safety features do reactors have toprevent overheating?

Nuclear reactors are equipped with several safety features to prevent overheating, including redundant cooling systems, such as emergency core cooling systems (ECCS), which activate if the primary cooling fails. Additionally, reactors utilize control rods made of neutron-absorbing materials that can be inserted into the core to reduce the fission reaction and heat generation. Containment structures also help manage heat and pressure, while monitoring systems provide real-time data on temperature and pressure to ensure safe operation. Together, these features create multiple layers of protection against overheating.
