Core Responsibilities

Primary Functions

Conduct comprehensive radiological surveys using a wide array of portable and fixed instrumentation to monitor, document, and control radiation and contamination levels throughout the facility.
Operate, maintain, and calibrate highly sensitive radiation detection equipment, ensuring all instruments are functioning within precise technical specifications and regulatory requirements.
Collect and perform detailed analysis on air, water, and surface samples to detect and quantify radioactive contamination, preparing reports and documenting findings meticulously.
Implement and enforce the principles of ALARA (As Low As Reasonably Achievable) to minimize radiation exposure for all plant personnel and contractors during routine and outage activities.
Provide direct radiological support and job coverage for maintenance, operations, and engineering tasks in radiologically controlled areas (RCAs), including pre-job briefings and real-time monitoring.
Issue and manage dosimetry devices (e.g., TLDs, electronic dosimeters) to track and document individual and collective radiation dose, ensuring compliance with federal limits.
Perform routine and corrective maintenance, troubleshooting, and repair on complex mechanical, electrical, and instrumentation and control (I&C) systems associated with the reactor and supporting equipment.
Execute detailed preventative maintenance procedures on critical plant components, such as pumps, valves, motors, and control circuits, to ensure system reliability and prevent equipment failure.
Utilize and interpret technical documentation, including piping and instrumentation diagrams (P&IDs), electrical schematics, logic diagrams, and vendor manuals, to diagnose and resolve equipment issues.
Operate, monitor, and test reactor control systems and power generation equipment from control rooms or in the field, under the direction of licensed operators.
Control the posting, labeling, and barricading of radiological areas, high-radiation areas, and contaminated zones to prevent inadvertent access and control the spread of contamination.
Support the handling, packaging, and shipment of radioactive materials and waste in strict accordance with Department of Transportation (DOT) and Nuclear Regulatory Commission (NRC) regulations.
Respond as a critical team member to plant emergencies, including radiological incidents, fires, or medical events, by executing established emergency response procedures.
Decontaminate personnel, equipment, and plant areas using approved methods and chemical solutions to restore them to a clean and safe condition.
Perform and document equipment lockouts/tagouts to ensure systems are de-energized and in a safe condition for maintenance work, following rigorous plant safety protocols.
Install, inspect, and test instrumentation and control devices, including transmitters, sensors, controllers, and final control elements, ensuring accurate process monitoring.
Maintain comprehensive and accurate logs, records, and databases of all maintenance activities, radiological surveys, and equipment performance data for regulatory and historical purposes.
Support refueling operations by performing specialized inspections, fuel handling support, and a heightened level of radiological monitoring.
Calibrate and troubleshoot analytical chemistry equipment used to monitor plant water chemistry, ensuring corrosion and system integrity are maintained.
Operate remote handling tools and robotic equipment for tasks in high-radiation environments to minimize personnel exposure.

Secondary Functions

Actively participate in station safety committees, human performance improvement initiatives, and self-assessment programs to foster a robust safety culture.
Provide on-the-job training, coaching, and mentorship to junior technicians and supplemental contract personnel to ensure skill development and procedural adherence.
Assist engineering teams with data collection, special testing, and implementation of plant modifications or equipment upgrades.
Participate in regular and graded emergency preparedness drills and exercises to maintain proficiency in emergency response roles.
