Radiator LNTR: The Last of the Line

Hello, and welcome back to Beyond NERVA! Today, we’re finishing (for now) our in-depth look at liquid fueled nuclear thermal rockets, by looking at the second major type of liquid NTR (LNTR): the radiator-type LNTR. If you’re just joining us, make sure to check out the introduction (available here) and the bubbler post (available here) […]

Dumbo: America’s First Forgotten NTR

Hello, and welcome back to Beyond NERVA! Today, in our first post in the Forgotten Reactors series, we’re going back to the beginnings of astronuclear engineering, and returning to nuclear thermal propulsion as well, looking at one of the reactors that’s had a cult following since the 1950s: the pachydermal rocket known as DUMBO. In […]

Carbides: Nuclear Thermal Fuels of the Past and Future

Hello, and welcome to Beyond NERVA! Today, we’re looking at a different kind of fuel element than the ones we’ve been examining so far on this blog, one that promises higher operation temperatures and therefore more efficient NTRs: carbide fuel elements. We’ll also look at a few different options for NTR designs using carbide fuels: […]
