Which process does not typically occur during MFP cleanup cycles?

During Main Feedwater Pump (MFP) cleanup cycles, the focus is primarily on maintaining the cleanliness of water within the systems to ensure efficient operation and avoid contamination. The process that does not typically occur during these cleanup cycles is the shutdown of auxiliary equipment.

Shutting down auxiliary equipment is not aligned with the objectives of a cleanup cycle. Instead, the goal is to maintain operational readiness while enhancing the performance of the system. Clean-up activities generally aim to flush stagnant water to remove debris, start condensate pumps to manage water flow, and filter water through polishers to ensure it meets quality standards. Each of these actions serves to improve the condition and efficiency of water within the system, ensuring optimal functioning.

In contrast, shutting down equipment could lead to a disruption in the cleanup process and potentially allow for the accumulation of contaminants or stagnant water. Therefore, this option does not fit within the typical activities performed during MFP cleanup cycles.
