U.S. Citizen Only
Responsibilities
Assist ongoing AMA analyses by performing neutronic, thermal hydraulic, fuel performance, engine cycle, or mechanical analyses of candidate nuclear propulsion system concepts:
Evaluate the parametric design space through assessment of system-level performance and any technical or programmatic risks
Independently develop and implement models to perform sensitivities related to candidate engine concept designs
Perform steady state and transient analyses to inform overall system performance and possible test objectives for an NTP or NEP demonstration
Communicate technical data to a multidisciplinary team of engineers and project managers via presentations and technical report writing
Support the ongoing assessment of the radiation environment and dose mitigation strategies for ground testing as well as in-space operation
Support relevant analyses and trades to determine required technology maturation of reactor components and facilities development for space reactor systems
Perform literature review and documentation to assist in ongoing space reactor system development and programmatic planning efforts
Publish reports, papers, and articles on findings
Qualification
