What kinds of safety factors are used in a nuclear reactor?

Nuclear reactors employ multiple safety factors, including containment structures, redundant safety systems, and active and passive cooling mechanisms. Containment buildings are designed to prevent the release of radioactive materials in case of an accident. Redundant safety systems ensure that if one system fails, others can take over to maintain safe operations. Additionally, passive cooling systems rely on natural processes to remove heat without external power, enhancing safety during emergencies.
