Abstract : Nucleonic techniques using continual gamma-ray emission phenomena were extensively analyzed in the application of gauging (storable) propellants in the Space Shuttle Vehicle Orbital Maneuvering System (OMS) tanks when under zero-gravity conditions. Parametric analyses were used to identify viable gauging concepts which were, in turn, subjected to subsystem and engineering tradeoffs. Based on these tradeoffs, a flight-type nucleonic gauging system was designed, fabricated and tested. (Modified author abstract)
