Description

Idaho National Laboratory has several positions available for Senior Reactor Operators to work in our Advanced Reactor Division. This position supports INL and Reactor Vendors collaboration in design, operations support, reactor fueling, operations, and reactor removal. Our team works a rotating schedule located out of our Materials and Fuels Complex.

The Idaho National Laboratory (INL) is leading the Nation's efforts in development and deployment of Micro-Reactors. With the establishment of the National Reactor Innovation Center (NRIC) and in partnership with multiple reactor technology vendors INL is poised to take the new generation of Micro-Reactors from the drawing board to reality. In support of this expansion multiple facilities are being re-purposed to house these reactors, supporting a series of installation, startup, testing, and removal activities. The reactors will use cutting edge technology and design requiring highly qualified Operators to understand the reactor dynamics, reactivity control systems, Balance of Plant equipment, and operating sequences. These projects will be executed on accelerated timelines requiring staff to be involved in aspects of Design, Safety Basis Development, Equipment Layout and Fabrication, Training and Procedure Development, System Operability Testing, Reactor Fueling, Transport, Assembly, and Disassembly.

As a Senior Reactor Operator reporting to the Shift Supervisor, you are responsible for safely directing Operations, Vendor/Subcontractor, and Maintenance personnel to execute a broad variety of assigned tasks. Responsible for execution of procedures to ensure that the limits for the assigned reactor are adhered to, ensuring that the safety boundaries and limits are always respected as the highest priority, while ensuring that simultaneous excellence is achieved in efficiency and reliability of work scope execution.

Responsibilities Include:



  • Accountable to the Reactor Manager and/or Shift Supervisor for the execution of all operations and testing of the assigned reactor project.
  • Ensuring facility criticality safety controls are understood and implemented during fuel fabrication/assembly and reactor fueling activities.
  • Actively participate in the development review and approval as assigned for preparatory procedures, site preparation plans, transport plans, installation and disassembly plans, training materials, reactor fueling, and commissioning planning for assigned micro-reactors.
  • Ensure reactor safety through the personal oversight/operation of the reactivity management and safe shutdown systems and the implementation of required controls to ensure that all operations are conducted with the required conservatism.
  • Support and adherence to a strict Nuclear Safety Culture that executes all tasks safely and deliberately. Provide leadership and mentoring of staff to ensure standards of performance and Conduct of Operations are in accordance with BEA expectations. Ensure the principles of ALARA are integrated into all aspects of reactor assembly, fueling, operations, transport, and disassembly activities.
  • Direct and oversee reactor testing, ensuring it is performed in strict conformance with Technical Safety Requirements, Facility Safety Analysis requirements and other documents that make up the reactor Safety Authorization Basis, and other approved implementing documents, procedures and operating manuals.
  • Control work performed on the assigned reactor and facility systems. Review proposed changes to reactor/facility controlling documents to ensure they are compatible with safe and efficient operation and other organizational objectives. Ensure reactor/facility activities are conducted in accordance with approved plans and schedules and that plant conditions are such that the work can be performed safely.
  • Maintain Senior Reactor Operator Certification. Responsible for training and certification of all operations personnel as assigned. Ensure that only certified/qualified and proficient individual operate reactor/facility equipment and watch stations.
  • Provide leadership example and mentoring of staff in nuclear safety and just culture principles, utilizing techniques that will reinforce the expected standards of the safety culture through the organization.
  • Provide work direction/oversight to shift operating personnel during reactor testing, steady state and abnormal operations, reactor startups, and emergency situations. Take required actions during emergencies in accordance with approved Emergency Procedures.
  • Coordinate and provide liaison with construction, vendor, waste and other support groups for safe, efficient, and effective installation, transport, fueling, operation, and de-mob of the assigned reactor as directed by the Shift Supervisor.
  • Direct the shutdown or restriction of operations whenever judgement dictates that such a restriction is necessary to protect the health and safety of the public, workers, or to protect property.
  • Direct operations, maintenance, and testing processes authorized by the Plan of the Week/Day within the bounds of site and contractual requirements.
  • Direct operations of the assigned reactor plant and associated equipment using approved procedures.
  • Complete and maintain qualifications in designated specialized areas of facility and process operations.


Knowledge/Skills/Abilities:



  • Understand all DOE and BEA requirements for nuclear facility shutdown and safe reactor operations, and apply these requirements to determine required scopes, activity schedules, and required resources. Ensure the reactor is operated within technical specification and DSA requirements. Maintain nuclear and personnel safety as the highest priority but achieve simultaneous excellence in efficient and reliable execution of work scope.
  • Understanding of conduct of operations and excellent knowledge of basic engineering theory.
  • Using logic and reasoning to identify the strengths and weaknesses of alternative solutions, conclusions, or approaches to problems.
  • Understanding technically complex written direction in work-related documents.
  • Identifying complex problems and reviewing related information to develop and evaluate options and implement solutions.
