I like collecting metals and patches. I recently started designing a software model of an RBMK reactor. That's the reactor type the blew up at Chornobyl. I'm fascinated by the type because of it's complexity, and modelling the neutronics, nuclear byproducts, and steam hydrolics is a great problem

RISO fuel and a compact design are built for a simpler safety case than large reactors need. Zero-power testing proves the neutronics work.

Thorium has a long history partly because the fuel cycle and neutronics can be elegant on paper, but engineering and licensing are different problems.

A zero-power run answers specific questions about neutronics and operator training before thermal operation begins. Calling it a milestone is fair; calling it a power demonstration would be misleading.

There's a YouTube video featuring an older simulator (now freely available) where the creator demonstrated exactly how all this happened. It's about 41 minutes and involved using a "cheat" system to set conditions exactly right, but it might be educational for some.

Neutronics Scoping Tool
Plug in your reactor type, size, and enrichment and get info about how much fuel you need, how long it will run, how much leakage there is, etc.

Here's the Neutronics Scoping Tool, which allows you to dial in a certain core height, radius, enrichment, and power rating and see if it will go critical and how long it will run. Then, it estimates the fuel LCOE, average discharge burnup, and a whole lot more. www.youtube.com/watch?v=GQzD...

Hey TRISO modelers, when you build a neutronics input with TRISO fuel, what are your favorite ways to set a given packing fraction without cutting off particles on the edge of your pebble or compact? Does everyone just write a packing script?
