A professional who monitors plant safety status, advises operations staff, and prepares technical reports for operation of thermal-nuclear reactor at electric-power generating station. Responsibilities include:

• Observes control-room instrumentation systems and confers with operating personnel to ensure safe operation of plant.
• Walks throughout plant and observes machinery, equipment, and operating procedures to identify potential hazards.
• Examines locations of accidents and transients (sudden changes of voltage or load) and obtains data to formulate preventive measures.
• Implements changes in systems, procedures, structure, or equipment to improve safety.
• Compares critical parameters with plant transient predictions and accident analysis and determines whether response of plant safety systems is sufficient.
• Formulates corrective actions, calculates critical parameters from raw data, and computes rate of control rod withdrawal during reactor startup.
• Confers with operating personnel to provide technical assistance and to discuss maintenance activities, abnormal conditions, and safe operation of plant.
• Prepares reports to inform management officials of any proposed changes or irregularities in plant operation or systems.
