About the role The Nuclear Company is seeking a Siting Engineer to serve as the technical owner of a site across its full development life cycle. This role works alongside the Origination group during screening and qualification of candidate sites, then takes the formal handoff of land and the site technical baseline at the FEL 0 admission gate and carries the site through characterization, licensing, and design integration (FEL 1–3) to readiness for construction.
You are the continuity of site knowledge across the Origination/Development boundary: the person who ensures that what was promised at admission is what gets characterized, licensed, and ultimately built. The ideal candidate combines hands-on site characterization experience with working fluency in NRC siting regulations and the discipline to produce licensing-grade documentation inside a stage-gate framework.
Responsibilities Origination Support & FEL 0 Handoff Provide technical siting support to the Origination group during screening: fatal-flaw assessments, hazard standoff analyses (NRC Regulatory Guide 1.91), buildable-area and cooling water evaluations, and population/exclusion criteria checks (10 CFR Part 100, Regulatory Guide 4.7) Validate candidate site packages against the FEL 0 Entry Boundary Conditions and confirm the technical basis for admission decisions Receive the formal handoff of land control, geospatial baseline, and site technical data at FEL 0 admission, and own that baseline through all subsequent phases Site Characterization (FEL 1–3) Scope, procure, and manage geotechnical, geological, seismological, hydrological, and ecological investigation programs Stand up and operate site meteorological monitoring programs (Regulatory Guide 1.23) meeting ESP/COL data quality and duration requirements Maintain the site GIS datasets, land control mapping, and survey baseline; manage characterization consultants and field subcontractors Licensing & Environmental Support Prepare site-related portions of ESP and COL applications under 10 CFR Part 52, including SSAR/FSAR Chapter 2 inputs, consistent with NUREG-0800 and NUREG-1555 Provide siting inputs to Environmental Reports and support NRC pre-application engagement, audits, and RAI responses on site matters Reconcile site characteristics against the plant site parameter envelope and manage departures and open items to closure Co
