Timber Wind: America’s Return to Nuclear Thermal Rockets

 Hello, and welcome to Beyond NERVA! Today, we’re continuing to look at the pebble bed nuclear thermal rocket (check out the most recent blog post on the origins of the PBR nuclear thermal rocket here)! Sorry it took so long to get this out… between the huge amount of time it took just to find […]

Pebblebed NTRs: Solid Fuel, but Different

Hello, and welcome back to Beyond NERVA! Today, we’re going to take a break from the closed cycle gas core nuclear thermal rocket (which I’ve been working on constantly since mid-January) to look at one of the most popular designs in modern NTR history: the pebblebed reactor! This I should have covered between solid and […]

The Nuclear Lightbulb – A Brief Introduction

Hello, and welcome back to Beyond NERVA! Really quickly, I apologize that I haven’t published more recently. Between moving to a different state, job hunting, and the challenges we’re all facing with the current medical situation worldwide, this post is coming out later than I was hoping. I have been continuing to work in the […]

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) […]

The Bubbler: Liquid NTRs Without Barriers

Hello, and welcome back to Beyond NERVA! Today, we continue our look at liquid fueled nuclear thermal rockets (LNTRs), with a deep dive into the first of the two main types: what I call the bubbler LNTR. This potentially attractive form of advanced NTR is a design that has been largely forgotten in the history […]

Fluid Fueled NTRs: A Brief Introduction

 Hello, and welcome back to Beyond NERVA! This is actually about the 6th blog post I’ve started, and then split up when they ran more than 20 pages long, in the last month, and more explanatory material was needed before I discussed the concepts I was trying to discuss (this blog post has also been […]
