WebbPhoebus was a series of nuclear reactors, designed and built in the 1960s as part of the Rover program, to meet the needs of an interplanetary mission (see nuclear propulsion ), … Webbused in the 75 klbf Phoebus-1B, 250 klbf Phoebus-2A, 25 klbf Pewee and the 55 klbf NERVA NRX series of engines. These elements were bundled around and supported by cooled coaxial core support tie tubes. Six elements per tie tube were used in the higher power Phoebus and NRX reactor series.

http://large.stanford.edu/courses/2011/ph241/hamerly1/ WebbThe study is based on the use of a reactor building originally built for the UHTREX reactor, and the use of some reactor hardware and reactor design and fabrication technology remaining from the Phoebus-2 reactor of the Rover nulcear rocket propulsion program. The facility is therefore currently identified as the PHOEBUS/UHTREX facility. Phoebus ran into opposition from SNPO, which wanted a 20,000 MW reactor. LASL thought that the difficulties of building and testing such a large reactor were being taken too lightly; just to build the 4,000 MW design required a new nozzle and improved turbopump from Rocketdyne. Visa mer Project Rover was a United States project to develop a nuclear-thermal rocket that ran from 1955 to 1973 at the Los Alamos Scientific Laboratory (LASL). It began as a United States Air Force project to develop a nuclear-powered Visa mer In principle, the design of a nuclear thermal rocket engine is quite simple: a turbopump would force hydrogen through a nuclear reactor, where it would be heated by the reactor to very high temperatures and then exhausted through a rocket nozzle to produce thrust. … Visa mer The first phase of Project Rover, Kiwi, was named after the flightless bird of the same name from New Zealand, as the Kiwi rocket engines were not intended to fly either. Their function was to verify the design and test the behavior of the materials used. The … Visa mer Early concepts During World War II, some scientists at the Manhattan Project's Los Alamos Laboratory, … Visa mer By 1957, the Atlas missile project was proceeding well, and with smaller and lighter warheads becoming available, the need for a nuclear upper stage had all but disappeared. On 2 … Visa mer Nuclear reactors for Project Rover were built at LASL Technical Area 18 (TA-18), also known as the Pajarito Site. Fuel and internal engine … Visa mer The next step in LASL's research program was to build a larger reactor. The size of the core determines how much hydrogen, which is necessary for cooling, can be pushed through it; … Visa mer how solar cell works animation
