'''Aircraft Nuclear Propulsion''' (ANP) was a [[United States Air Force]] program which worked to develop a nuclear propulsion system for aircraft. It was the follow-on to the USAF's '''Nuclear Energy for the Propulsion of Aircraft''' (NEPA). NEPA was launched in May, 1946, and operated until May 1951, when the efforts were transferred to the ANP. The USAF pursued two different systems for nuclear powered jet engines, the '''Direct Air Cycle''' concept which was developed by [[General Electric]], and '''Indirect Air Cycle''' which was assigned to [[Pratt & Whitney]]. The program was ultimately intended to result in the development and flight testing of the [[Convair X-6]], but was cancelled in 1961 before that aircraft was built.<ref name=radiationworks>[http://web.archive.org/web/20060302180919/http://www.radiationworks.com/flyingreactor.htm ''Nuclear Powered Aircraft'', quoting Brookings Institute text]</ref>

The '''După Fântână River''' is a [[tributary]] of the [[Pârâul Ţigăncilor]] in [[Romania]].
==Direct Air Cycle program==
The General Electric program, which was based at [[Evendale, Ohio]], was pursued because of its advantages in simplicity, reliability, suitability and quick start ability. Conventional jet engine compressor and turbine sections were used, with the compressed air run through the reactor itself to heat it before being exhausted through the turbine. This program produced the successful X-39 engine, two modified GE [[General Electric J47|J47s]] with heat supplied by the Heat Transfer Reactor Experiment-1 (HTRE-1). The HTRE-1 was replaced by the HTRE-2 and eventually the HTRE-3 unit powering the two J47s. The HTRE-3 used "a flight-type shield system" and would probably have gone on to power the X-6 had that program been pursued.

==Indirect Air Cycle program==
The Indirect Air Cycle program was assigned to Pratt & Whitney, at a facility near [[Middletown, Connecticut]]. This concept would have produced far less radioactive pollution. One or two loops of liquid metal would carry the heat from the reactor to the engine. This program involved a great deal of research and development of many light-weight systems suitable for use in aircraft, such as heat exchangers, liquid-metal turbo pumps and radiators. The Indirect Cycle program never came anywhere near producing flight-ready hardware.

The ANP program required that [[Convair]] modify two B-36s under the MX-1589 project. One of these, the Nuclear Test Aircraft (NTA), was an NB-36H modified to study shielding requirements for an airborne reactor, to determine whether a nuclear aircraft was feasible. This was the only known airborne reactor experiment by the U.S. with an operational nuclear reactor on board. The NTA flew a total of 47 times testing the reactor over West Texas and Southern New Mexico. The reactor, named the Aircraft Shield Test Reactor [ASTR], was operational but did not power the plane, rather the primary purpose of the flight program was shield testing.

Based on the results of the NTA, the X-6 and the entire nuclear aircraft program was abandoned in 1961.
