Thermalhydraulics Analysis Of The Unit-Cell Nuclear Light Bulb Rocket Engine, Vojislav Banjac May 1995

Thermalhydraulics Analysis Of The Unit-Cell Nuclear Light Bulb Rocket Engine, Vojislav Banjac

Nuclear Engineering ETDs

This dissertation presents a detailed thermalhydraulics analysis of the unit-cell derivative of the Nuclear Light Bulb (NLB) rocket engine. The NLB engine is a gas core nuclear rocket first proposed in the 1960's by the then-United Aircraft Research Laboratories (UARL); its unit-cell derivative consists of a low-temperature moderator/reflector as well as segmented propellant channels, both proposed with the intent of increasing the keff of the system.

The results of this work can be grouped into two major areas: (1) thermal and neutronics analysis of the engine, and (2) investigation of the feasibility of the engine over a ...
