Hey guys, it's been awhile since I've been around here but I could use some help! I'm trying to throw together a rudimentary neutron diffusion simulation of Chicago Pile 1 but I'm having trouble finding some technical details on it. I need to find details on the dimensions of the reactor. Things like how the uranium metal/oxide blocks, graphite blocks, and control rods were arranged. Basically I need a labeled and dimensioned technical drawing of the reactor. If something like that is super hard to come by then I could at least use a good general description of the uranium distribution along with at least the external dimensions of the pile. I've read that the whole reactor is approximately the size of a squash court and that the pile is somewhat of a flattened ellipsoid, but I would love to have a better picture than that. I'm also having trouble finding a few other technical details such as U-235 enrichment % of the uranium metal and oxides and what kind of material the control rods were. There is a ton of information available on the history of this reactor but the technical details are sparse. If anyone has any technical sources they could point me to I would greatly appreciate it! Thanks for your time!
