About The Position

We are seeking a Senior Consultant Energy – Remote. This remote position is based out of our Oak Ridge, TN office. Your role AtkinsRéalis US Nuclear is the subsidiary of AtkinsRéalis focused on serving government and commercial clients within the Nuclear sector in the United States. We are focused on being recognized as a premier nuclear solutions company in the United States, delivering engineering, licensing, operations, safety analysis, and project management services. Serves both legacy and new-build nuclear clients who are designing, building, upgrading, operating, and maintaining nuclear power generation and fuel cycle assets. We are a growing business, building on the foundation of our US government fuel cycle business, our international position as an original equipment manufacturer (OEM) and nuclear reactor technology provider, and our worldwide nuclear new-build and legacy nuclear fleet maintenance experience. Supports commercial nuclear projects as business and project needs develop. Provides senior technical leadership and consulting support in probabilistic risk assessment (PRA), risk-informed decision-making, and the integration of risk insights into licensing, design, operations, maintenance, and project execution. Supports operating plants, new-build projects, advanced reactor development, and other nuclear facility projects in the United States and internationally. Provides senior technical leadership and consulting support for PRA and risk-informed licensing activities supporting US and international commercial nuclear projects. Supports the planning, development, review, and application of Level 1, Level 2, and/or Level 3 PRA, as applicable to project scope and maturity. Reviews PRA methodologies, models, assumptions, results, and supporting documentation for technical quality, regulatory alignment, consistency, and fitness for purpose. Supports hazard identification, screening, evaluation, and risk quantification for internal events, shutdown conditions, internal flood, seismic events, high-wind events, and other external hazards. Evaluates plant response, system interactions, accident progression, system reliability, and risk-significant contributors, including reliability assessments of plant process, safety, balance-of-plant, and operating systems, to support informed safety, licensing, design, operational, and maintenance decisions. Integrates PRA insights into licensing strategies, safety cases, SSC classification, technical specifications, maintenance strategies, operating programs, and design decisions. Supports risk-informed and performance-based licensing approaches, including NEI 18-04 and RG 1.233 implementation, licensing basis event selection, SSC classification, defense-in-depth evaluation, and related license application content. Supports the development and application of risk monitors, operational risk assessments, and other PRA applications, as applicable to project needs. Develops, proposes, reviews, or advises on PRA methodologies, technical approaches, analysis assumptions, and model-development strategies. Coordinates PRA interfaces with deterministic safety analysis, severe accident analysis, source term development, emergency planning, fire protection assessments, and other nuclear safety analysis disciplines. Supports regulatory interactions, technical meetings, audits, workshops, and responses related to PRA and risk-informed licensing topics. Supports the preparation and review of proposals, scopes of work, schedules, estimates, and execution plans for PRA and risk-informed licensing activities. Provides mentoring, knowledge transfer, and technical development support to engineers and analysts and supports the growth of AtkinsRéalis’ PRA and risk-informed licensing capability. Ensures work is performed in accordance with applicable nuclear quality assurance requirements, project procedures, PRA standards, regulatory guidance, and client expectations. Performs other duties as assigned.

Minimum of 15 years of relevant nuclear industry experience, including significant experience in PRA, risk management, or risk-informed applications.
Demonstrated experience applying PRA insights to nuclear plant licensing, design, operations, maintenance, or safety decision-making.
Demonstrated understanding of nuclear plant systems, plant response, accident progression, operating practices, and underlying reliability principles.
Strong technical knowledge of PRA methods, risk-informed decision-making, and nuclear safety analysis.
Strong understanding of nuclear plant systems, operations, accident response, and safety functions.
Ability to rapidly develop familiarity with different reactor technologies, plant designs, regulatory frameworks, and licensing approaches.
Ability to interpret PRA results and translate risk insights into actionable licensing, design, operational, and maintenance decisions.
Familiarity with PRA software tools used for fault tree and event tree modeling, model quantification, external hazards analysis, risk monitoring, and related risk-informed applications.
Ability to evaluate the suitability, limitations, and quality of PRA software tools, models, and outputs for the intended technical, licensing, or operational application.
Ability to work effectively across PRA, deterministic safety analysis, licensing, engineering, operations, and other nuclear safety analysis disciplines.
Knowledge of applicable US and international nuclear licensing requirements, PRA standards, industry guidance, and quality assurance expectations.
Strong written and verbal communication, organizational, analytical, and problem-solving skills.
Ability to work independently, exercise sound technical judgment, and manage multiple priorities.
Must be a U.S. citizen in order to be considered.
