Which role is responsible for primary water chemistry in the reactor?

The role responsible for primary water chemistry in the reactor is the Engineering Laboratory Technician. This position is crucial because maintaining the correct water chemistry is essential for ensuring the safe and efficient operation of the reactor. The Engineering Laboratory Technician conducts tests and analyzes samples of the reactor's water to monitor its chemical properties, ensuring they remain within specified limits. Proper water chemistry helps prevent corrosion, minimize deposits, and maintain overall reactor health.

In contrast, the Chief Reactor Watch primarily oversees the reactor's operations and ensures that all systems function safely and efficiently, but does not focus specifically on water chemistry. The Reactor Electrical Operator manages electrical systems and components rather than water chemistry. The Reactor Mechanical Operator handles mechanical systems and equipment, which also does not directly involve the management of water chemistry. Each role is important for the reactor's overall operation, but the Engineering Laboratory Technician is specifically tasked with the critical responsibility of monitoring and maintaining water chemistry.
