Core Responsibilities

Primary Functions

Perform complex thermal-hydraulic, neutronic, and fuel performance analyses to ensure the safe and efficient operation of the reactor core.
Develop, maintain, and execute sophisticated computer models and simulations of reactor systems using industry-standard codes like MCNP, RELAP5, or SCALE.
Prepare, review, and approve critical engineering design documentation, technical specifications, and calculation packages for plant modifications and upgrades.
llaborate directly with plant operations teams to provide real-time engineering support, troubleshoot emergent issues, and develop solutions for equipment or system deficiencies.
Manage and oversee the nuclear fuel cycle, including the development of core loading patterns, fuel procurement strategies, and irradiated fuel management plans.
Conduct comprehensive safety analyses and risk assessments (e.g., Probabilistic Risk Assessment - PRA) to identify potential hazards and ensure compliance with the plant's design and licensing basis.
Serve as a technical subject matter expert during internal assessments, audits, and regulatory inspections by bodies such as the Nuclear Regulatory Commission (NRC).
Develop and implement long-term equipment reliability programs, component health monitoring, and preventative maintenance strategies for critical nuclear systems.
Lead or participate in root cause analysis investigations for significant plant events or component failures, recommending robust corrective actions to prevent recurrence.
Evaluate the impact of aging and degradation on reactor components and materials, developing strategies for mitigation, repair, or replacement.
Author and review technical reports, licensing submittals, and responses to regulatory inquiries to ensure accuracy, clarity, and technical defensibility.
Provide engineering oversight for refueling outages, including planning, execution, and post-outage system restoration and testing.
Design and analyze radiation shielding for plant areas and equipment to ensure personnel exposure is maintained As Low As Reasonably Achievable (ALARA).
Interpret and ensure strict adherence to technical specifications, federal regulations (e.g., 10 CFR 50), and industry codes and standards (ASME, IEEE).
Develop and validate testing methodologies for new or modified systems to ensure they perform as designed before being placed into service.

Secondary Functions

Support ad-hoc data requests and perform exploratory analysis on reactor performance, component health, and operational trend data.
Contribute to the long-term strategic vision for plant modernization, life extension, and capital improvement projects.
Collaborate with multidisciplinary project teams, including civil, mechanical, and electrical engineers, to ensure the successful integration of complex plant modifications.
Mentor junior engineers and technical staff, providing guidance, feedback, and knowledge transfer to develop the next generation of nuclear professionals.
Prepare and deliver technical presentations and briefings to internal management, cross-functional teams, and external regulatory agencies.
Participate in industry working groups and conferences to stay abreast of emerging technologies, operational experience, and evolving regulatory landscapes.
Support emergency response organization duties, providing critical technical assessment and recommendations during drills, exercises, and actual plant emergencies.
