Wikipedia – The fission-fragment rocket is a rocket engine design that directly harnesses hot nuclear fission products for thrust, as opposed to using a separate fluid as working mass. The design can, ...

Aerogel core fission fragment rocket engine concept was awarded a NIAC grant by NASA, ... NASA needs such a rocket and its components to be able to withstand temperatures above 4,600 degrees ...

What Is a Fission Fragment Rocket Engine? FFREs are not a new concept in themselves, but many have massive technical hurdles to overcome before they can be considered useful.

Fission Fragment Rocket Engine Thrust Velocity at 1.7% of light speed. April 7, 2017 April 12, 2012 by Brian Wang. Proposal for a Concept Assessment of a Fission Fragment Rocket Engine (FFRE) ...

While we’ve discussed them here at UT before, NASA’s Institute of Advanced Concepts has provided a grant to a company called Positron Dynamics for the development of a novel type of nuclear fission ...

An international team of researchers, including scientists from Science Tokyo, has developed a five-dimensional ...

Nuclei undergoing fission can be described by a multi-dimensional potential-energy surface that guides the nuclear shape evolution—from the ground state, through intermediate saddle points and ...

A five-dimensional (5D) Langevin approach developed by an international team of researchers, including members from Science Tokyo, accurately reproduces complex fission fragment distributions and ...

Subtle quantum effects within atomic nuclei can dramatically affect how some nuclei break apart. By studying 100 isotopes with masses below that of lead, an international team of physicists uncovered ...

Hence, fission is a form of elemental transmutation. The by-products include free neutrons, photons usually in the form gamma rays, and other nuclear fragments such as beta particles and alpha ...
