“Heater One” & “Heater Two”

The Heat Transfer Reactor No. 1 (HTRE-1 or “Heater One”) was part of the Air Force’s effort to develop a nuclear-powered aircraft. In a ground test, the reactor went to full power in January 1956 and demonstrated the principle of nuclear-powered turbojet engines.

HTRE-1 was converted to HTRE-2 (“Heater Two”) and it became the world’s largest materials test reactor. HTRE-2 subjected test fuels to neutron flux and 2800˚ temperatures, advancing the state-of-the-art for materials.

7. Htre-3
“Heater Three”

HTRE-3 or “Heater Three” was built more like an aircraft with the reactor, engine, shielding and heat transfer systems in a horizontal configuration. Eventually the reactor could start and run two turbojet engines at a time.

“The engine itself, including the reactor, was less than ten feet long. What you see is the framework that was needed to make sure the reactor did not take off across the desert. But the framework also contained many instruments to measure the performance of the reactor and jet engine.” Jay Kuntze, Aircraft Nuclear Propulsion physicist and engineer.

8. Lead-Shielded Diesel Locomotive from the Aircraft Nuclear Propulsion Project
This locomotive, running on four tracks, would have towed the radioactive airplane, which was never built, inside the hangar, which was built, and demolished when the project was cancelled in 1961. The engineer would sit in the cylindrical cab, looking out the thick window.
