• Maintaining subject-matter expertise in nuclear criticality safety regulatory and CNL program requirements, ensuring their effective application through a robust and compliant Nuclear Criticality Safety Program.
• Maintaining current knowledge of applicable nuclear criticality safety regulatory requirements, including Canadian Nuclear Safety Commision (CNSC) requirements, CNL interpretations and implementations, and other applicable regulations, standards, and guidance.
• Interpreting regulatory requirements and, when needed, translating them into clear, implementable requirements within CNL’s requirements framework.
• Supporting the development, maintenance, and continuous improvement of the Nuclear Criticality Safety Program to ensure ongoing regulatory compliance and effectiveness.
• Authoring and reviewing Nuclear Criticality Safety Program documentation to ensure ongoing regulatory compliance and effectiveness.
• Interfacing with CNSC staff, auditors, inspectors, and other internal or external oversight bodies, as required, to support reviews, inspections, assessments, and issue resolution.
• Providing authoritative nuclear criticality safety support and oversight to ensure the safe and compliant execution of operations with fissionable material.
• Providing ongoing oversight of operations with fissionable material to ensure nuclear criticality safety requirements are met and maintained.
• Providing ongoing support to personnel performing, supporting, supervising, and managing operations with fissionable material to ensure general and area-specific nuclear criticality safety requirements are clearly understood and correctly implemented.
• Identifying, documenting, and supporting the resolution of nuclear criticality safety issues, non‑compliances, or adverse conditions, including providing technical input to corrective actions and verifying alignment with applicable requirements.
• Supporting operational planning, work authorization, and change management processes to ensure nuclear criticality safety requirements and risks are identified, evaluated, and controlled.
• Supporting the definition and communication of the scope, effort, and duration of required nuclear criticality safety involvement to ensure expectations are clearly understood by affected stakeholders.
• Authoring, reviewing, and supporting the development of technical analyses, including but not limited to criticality safety analyses, demonstrating that specific operations with fissionable material remain subcritical under normal and credible abnormal conditions.
• Performing technical work in accordance with all applicable requirements, including relevant procedures, standards, and regulatory expectations.
• Collaborating with other nuclear criticality safety subject matter experts, internal customers, and other required technical disciplines to support the development of complete and defensible analyses.
• Performing technical analyses using methods appropriate to the scope and complexity of the work, including but not limited to computational analyses using validated codes (e.g., SCALE/KENO), and appropriately post‑process, interpret, and document results.
• Producing clear, logical, and comprehensive documentation of the technical work that demonstrates compliance with all applicable requirements.
• Supporting and/or reviewing technical work performed by others to aid in development, providing technical guidance, and/or confirming technical accuracy and alignment with applicable requirements.
• Supporting the assessment of Nuclear Criticality Safety Program implementation and performance, and contributing to the identification and implementation of continuous improvement opportunities.
• Supporting and participating in internal and external reviews, assessments, audits, and inspections related to Nuclear Criticality Safety Program implementation.
• Leading or supporting assessments evaluating the Nuclear Criticality Safety Program against applicable regulatory requirements and CNL expectations.
• Identifying, documenting, and communicating gaps, weaknesses, or improvement opportunities in Nuclear Criticality Safety Program implementation.
• Providing regulatory and/or technical input to the development and implementation of corrective actions related to nuclear criticality safety findings, issues, or events.
• Leading or supporting the incorporation of operating experience, lessons learned, and assessment results into improvements to Nuclear Criticality Safety Program elements, guidance, and…
