THE HEAT EXCHANGER FOR THE PRATT AND WHITNEY HYDROGEN POWERED REX-III ENGINE IS THE SAME AS THE GE-310 NUCLEAR ENGINE

The radiator/heat exchanger set-up shows how the radiation problem was ultimately solved. The engineers placed a small SNAP-8 sized reactor in the middle of a reactor and cooled it with molten metal and circulated it through the heat exchanger. 

The SNAP-8 could easily fit inside the J-58 engine of the Blackbird. 

The autoignition temperatures for JP-7 depending on the atmospheric conditions range from 900K to 1050K or in fahrenheit 1160F to 1430F [1]. So, if what we know about JP-7 from open sources is true, then it was developed to autoignite at altitude when exposed to the 900-1050 Kelvin temperature of the air coming from the radiator. 

This was a test of the radiator of the liquid core aircraft reactor. 

According to the GAO the NEPA/ANP program was billed as a competitive program between different paired companies. This is the lie we were told. These images show that GE and Pratt and Whitney were working together in order to build the nuclear jet engine. Doubtlessly Lockheed and Convair (General Dynamics) were doing the same thing. In fact the documentary record shows they had a "special relationship."
