About the Job

Requirements

  • A bachelor's degree in science, such as health physics or biology, and/or engineering, such as nuclear, chemical, or mechanical engineering, from an accredited college or university is required.
  • Knowledge of the principles, theories, and practices of health physics and radiation safety, including implementation of programs involving byproduct, source, or special nuclear materials in power reactor, nuclear fuel fabrication, medical, industrial, academic, decommissioning, and/or Independent Spent Fuel Storage Installation settings.
  • Level III typically requires five years of experience in the health physics or radiation safety field.
  • Level IV typically requires ten years of experience in the health physics or radiation safety field.
  • Experience developing written procedures to implement regulatory and code or standard requirements, and applying regulatory guidance.
  • Working knowledge of relevant industry codes, standards, and best practices for health physics, radiation surveying and monitoring, radiation safety training, ALARA best practices, and Nuclear Regulatory Commission requirements for nuclear facilities.
  • Understanding of Nuclear Regulatory Commission-regulated nuclear facility operation, ventilation systems, and respiratory protection to reduce worker exposure to radioactive airborne contamination, and oversight of safe handling of radiological materials.
  • Experience using MCNP, MicroShield, or other computer codes and models or methods for dose assessments.

Responsibilities

  • Develop occupational radiation protection practices and ALARA program requirements for a first-of-its-kind reactor or nuclear fuel fabrication facility.
  • Assist in establishing a radiation safety program to ensure regulatory compliance with local, state, and federal requirements, including those of the Nuclear Regulatory Commission, the Occupational Safety and Health Administration, and state laws.
  • Evaluate and analyze radiological health hazards, or remediate hazards involving byproduct, source, or special nuclear material.
  • Collaborate and communicate with project leadership and team stakeholders to provide progress updates, maintain priorities, adapt to change, and raise concerns about project or timeline issues.
  • Provide technical expertise and guidance to identify, analyze, and resolve problems of increasing scope and complexity.
  • Contribute to team decisions in support of business goals and objectives by planning, organizing, estimating, scheduling, and monitoring work; adapt to changing priorities and situations and make decisions that may affect team work.
  • Prepare accurate technical reports, correspondence, documentation, calculations, and sketches related to defined problems and analyses of increasing scope and complexity.
  • Conduct technical studies and complete routine technical projects with minimal oversight, increasing independence in managing project schedules and interfaces.
  • Develop and implement radiation safety programs and procedures, including ALARA, respiratory protection, internal and external dosimetry, air sampling and monitoring, contamination control, radiological surveys and monitoring, instrument selection and maintenance, radiation work permitting, and environmental monitoring.
  • Perform hazard assessments and define job safety requirements in work permits.
  • Participate in Process Hazards Analysis with multidisciplinary teams to identify potential criticality, radiological, chemical, and fire or explosion hazards and determine potential consequence levels for the Integrated Safety Analysis process.
  • Consult with and advise operations, maintenance, and engineering personnel on radiation protection or occupational safety and health impacts of proposed changes to processes, procedures, and facility designs or modifications.
  • Participate in design reviews.
  • Conduct surveillances, inspections, walk-downs, investigations, and audits or assessments of radiological material operations and unusual incidents to ensure compliance with approved procedures and safety bases.
  • Review and audit safety and health programs for adequacy, compliance, and effectiveness.
  • Develop a Health Physics/Health & Safety Technician Training and Qualification Plan and train employees.
  • Develop and deliver radiation safety training for all personnel.
  • Develop and revise safety postings and operator aids to implement clear, understandable, and achievable administrative controls.
  • Prepare and deliver recommendations to managers, safety committee representatives, and employees.
  • Provide support to the emergency response team.
  • At Level III, execute the core tasks and responsibilities with minimal supervision and own technical scope involving coordination of multiple individual contributors in a specific area.
  • At Level IV, lead execution of core tasks and responsibilities without close supervision and with some latitude for independent judgment; provide feedback and guidance to more junior team members; and share industry best practices and standards across the team.
  • Perform other duties as assigned by the manager.

About the Company

X-energy

Develops SMR reactors and TRISO fuel

X-energy designs and develops Generation IV high-temperature gas-cooled pebble-bed reactors and the TRISO-X fuel for small modular reactors (SMRs). Its modular reactor units use TRISO fuel to operate at high temperatures, producing heat that powers electricity generation or process heat through conventional power cycles, with safety features built into the fuel and design. The company differentiates itself by combining a fully modular Gen IV gas-coooled platform with proprietary TRISO-X fuel and a clear path toward commercialization backed by substantial financing. Its goal is to deliver cleaner, safer nuclear energy at commercial scale by completing design, obtaining regulatory clearance, and deploying its SMR technology and fuel.
