  • Build source terms and model atmospheric dispersion using tools like HotSpot, RASCAL, MACCS, ARCON, or ALOHA
  • Support the Integrated Safety Analysis by characterizing consequence severity and informing safety control selection
  • Evaluate consequences against 10 CFR 70.61 performance requirements and dose/exposure criteria
  • Collaborate with criticality safety, fire protection, process, and licensing teams on accident scenario definition
  • Investigate consequence-related findings and support corrective action development

What they're looking for

  • Consequence and accident analysis methods
  • Radiological and chemical dispersion modeling
  • HotSpot, RASCAL, MACCS, ARCON, ALOHA or similar software
  • 10 CFR Part 70 regulations and compliance
