This is done in the " thermal reactor " chamber where the exhaust manifold would normally be on a conventional engine.
12.
Thermal reactors require less of the expensive fissile fuel to start, but are more sensitive to fission products left in the core.
13.
However, 242 Pu's low cross section means that relatively little of it will be transmuted during one cycle in a thermal reactor.
14.
In plutonium that has been used a second time in thermal reactors in MOX fuel, Pu-240 may even be the most common isotope.
15.
Mazda improved the fuel efficiency of the thermal reactor system by 40 % by the time of introduction of the RX-7 in 1978.
16.
Under certain conditions the pump injects air into the thermal reactor and at other times air is pumped through injectors into the exhaust ports.
17.
Early 12A engines also feature a thermal reactor, similar to the 0866 10A, and some use an exhaust port insert to reduce exhaust noise.
18.
In a normal thermal reactor, it has a very low fission product yield; thus, this isotope is not a significant contributor to nuclear waste.
19.
Although MOX fuel can be used in thermal reactors to provide energy, efficient fission of plutonium in MOX can only be achieved in fast reactors.
20.
Electric utilities, in a rare display of opposition to a government policy, revolted against the so-called advanced thermal reactor, saying it would be too expensive.
