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.

Apologies if this has been answered before and if so, please feel free to redirect me to the appropriate thread. I did do a quick search but the threads I found were a few months old and/or not ...

Crews will replace 256 of the 764 nuclear fuel assemblies in the reactor core with new fuel. The biannual fuel outages allow all fuel to be replaced on a rotating schedule every six years.

USSR was slightly ahead: the RD-0410 nuclear motor was tested in non-nuclear setup and in nuclear setup. NERVA program was abandoned before producing an engine. Both would produce a flying engine, ...

Six NERVA technology demonstrators were built between 1964 and 1973. The highest power threshold NASA could muster during testing was a scarcely believable 246,663 newtons (55,452 lbf) of thrust ...

The state-of-the-art NTP cycle is based on solid core Nuclear Engine for Rocket Vehicle Application (NERVA) class technology that is envisioned to provide a specific impulse (Isp) of 900 seconds ...

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 ...
