But compared to NERVA designs, his team used different channels to route the hydrogen through the reactor core and thermal management systems that transfer the heat to hydrogen. A drawing of the ...

Gosse’s proposal calls for a bimodal design based on a solid core NERVA reactor that would provide a specific impulse (I sp) of 900 seconds, twice the current performance of chemical rockets.

However, Project Rover and NERVA ... The hydrogen is fed into the reactor core, which has a matrix of longitudinal channels in which the hydrogen is heated to temperatures in excess of 2500° K.

Gas Core. A Gas Core reactor is even more difficult than a liquid, requiring a spinning pocket of uranium gas surrounded by hydrogen vapor. ... NASA’s side, Project NERVA ...

NASA's Ares V rocket will launch the cargo needed to build a Moon base - its second stage could be nuclear-powered, says a top scientist One problem with the 1960s design of an experimental ...

Over the course of the contract, which extends through 2019, BWXT will develop conceptual designs focusing on fuel elements and the reactor core. Three main challenges distinguish modern efforts ...

Terrani and his colleagues are working on it. The Oak Ridge team recently finalized the preliminary design for the 3D-printed core at the heart of its Transformational Challenge Reactor, or TCR.
