As a Nuclear Consequence Analysis Engineer at General Matter, you'll own the question at the heart of the facility's safety case: if something goes wrong, what actually happens? You'll quantify the radiological and chemical consequences of accident scenarios across the facility — building source terms, modeling dispersion, and estimating dose and exposure to workers, the public, and the environment. This is a systems-level role: your analyses define how severe each scenario is, directly driving which safety controls we credit and shaping the Integrated Safety Analysis (ISA) that underpins our 10 CFR Part 70 license. Many of the tools of this trade — MACCS and HotSpot among them — were built for DOE safety analysis under DOE-STD-3009, and the underlying consequence methodology carries over cleanly to the NRC's 10 CFR 70.61 performance requirements. If you've done this work at a DOE site or national lab, you're already speaking our language.

Develop consequence analyses for radiological and chemical release scenarios across normal, off-normal, and accident conditions.

Develop and document source terms for postulated accident sequences.

Model atmospheric dispersion and estimate downwind concentrations, doses, and exposures using codes such as HotSpot, RASCAL, MACCS, ARCON, ALOHA, or similar tools.

Support the Integrated Safety Analysis (ISA) by characterizing consequence severity and informing the selection of safety controls under 10 CFR Part 70.

Evaluate consequences against applicable performance requirements (e.g., 10 CFR 70.61) and dose/exposure criteria.

Collaborate with criticality safety, fire protection, process, and licensing teams to ensure consistent accident scenario definition.

Investigate consequence-related findings and support development of corrective actions as necessary.

Maintain accurate analyses, assumptions, and documentation to support audits and regulatory reviews.
