NASA and its partners have successfully tested a nuclear thermal propulsion (NTP) fuel that could revolutionize deep-space ...

Fast reactors use neutrons that are not slowed down by a moderator, such as water, to sustain the fission chain reaction. While only a fraction of natural uranium is used as fuel in existing thermal ...

A new type of nuclear thermal propulsion reactor fuel has been successfully tested at NASA’s Marshall Space Flight Center, with hopes that the fuel could take humans to Mars in the not-too ...

The Submarine Thermal Reactor plant (STR Mark I), the test version of the Nautilus machinery, commenced operating on May 31, 1953, in the desert of the Snake River plain, fifty-five miles west of ...

The fast neutron spectrum allows fast reactors to largely increase the energy yield from natural uranium as compared to thermal reactors. This high utilization of fuel can extend nuclear power ...

The production of transuranic actinides in thermal neutron fission reactors. (CC-BY-SA-3.0) A nuclide like that of 238 U is interesting in that has a non-zero rating in each of those three cross ...

candidate for this is the Nuclear Thermal Propulsion (NTP) system or nuclear rocket. First conceived of in 1945, this is a rocket that replaces burning chemical fuel with a nuclear reactor that is ...

While the reactor is at a “PDR level of maturity ... Osorio says that “qualifying an operational nuclear thermal propulsion engine for space transportation will require a ground-test ...

Milestone 3 is the thorium molten salt test reactor. It is planned to generate up to 1 MW of thermal output and to run for 30 days in the first instance. The main purpose of the 1 MW reactor test is ...
