What type of systems are typically used for safety interlocks in power plants?

Safety interlocks in power plants are critical for ensuring safe operations. These systems are designed to prevent the operation of equipment or processes that could lead to unsafe conditions. They achieve this by monitoring various parameters and, when certain thresholds are reached, they automatically shut down or restrict equipment to prevent hazardous situations.

The essence of safety interlocks lies in their core function to safeguard both personnel and equipment by ensuring that operations do not proceed unless all safety conditions are met. For instance, if a particular piece of machinery is operating outside of its safe parameters, the interlock system will intervene to halt operations, thereby preventing potential accidents such as equipment failure or even catastrophic events like explosions or fires.

In contrast, options that focus on enhancing energy consumption, allowing continuous operation, or increasing production levels do not prioritize safety and therefore do not align with the purpose of interlock systems. These aspects may be important for efficiency and productivity, but they are secondary to ensuring safe operation in potentially hazardous environments such as power plants.
