Sandia’s MELCOR software and multi‑decade consequence studies have turned safety uncertainty into quantitative assessments that regulators use to judge acceptability. Extending those models to advanced reactors is presented as a prerequisite for the NRC to evaluate, regulate, and thereby enable deployment of new reactor types.
— Who builds and controls the detailed safety models (and their assumptions) can determine whether advanced nuclear technologies clear the regulatory and political hurdles to scale.

Both cases turn on whether technical validation and safety modeling can substitute for decades of conservative, physical mitigation (water cooling in sprinklers/nuclear safety proofs). The article notes Sonic Fire Tech claims NFPA equivalency but has not released full test data, mirroring how safety modeling and open validation decide regulatory acceptance in high‑risk infrastructure.

The review documents how safety models and risk calculations (PRA) became the operational basis for licensing and regulatory decisions, showing the causal link from modeling methods to practical licensing outcomes and political controversy.

Sandia’s MELCOR code, the SOARCA study, and the explicit claim that without MELCOR capability enhancements the NRC 'would be unable to evaluate and regulate' future systems.
