Nuclear Launch Risk Modeling & Event Sequence Diagram (ESD) Development

The contract involves developing Event Sequence Diagrams to model accident scenarios associated with the nuclear-powered Rosalind Franklin Mission launched aboard SpaceX’s Falcon Heavy vehicle. The work focuses on identifying failure mechanisms, tracing causal chains, and analyzing potential consequences of system malfunctions during launch, ascent, or early flight phases. The diagrams will serve as risk modeling tools to evaluate how component failures could propagate under nominal and off-nominal conditions, with particular attention to nuclear payload safety and environmental impact. The subcontract is issued under NAICS code 541690, indicating it pertains to other scientific and technical consulting services, and is administered by NASA Kennedy Space Center with performance location specified as 90277, likely indicating a facility in the Los Angeles area associated with aerospace engineering support. The solicitation was posted in May 2026 and is classified as a subcontract, suggesting the primary contractor is managing the work on behalf of NASA, with deliverables focused on safety-critical system modeling for a high-consequence mission.
