First working nuclear reactor

The first working nuclear reactor was created on July 16, 2020 by D_Walks03/matthyno using materials sourced from event boss battles and from the town that they are in. The nuclear reactor is covered by obsidian and is in the town of Mount Eos. Nuclear reactors are known to be expensive, because they require 36 diamonds and an entire nether star, and making one is a huge feat, in reality or not.

Controversy from the first nuclear reactor
As stated by matthyno, the nuclear reactor itself was quite underwhelming originally for the following reasons :

"1. they're annoying to maintain you have to fill the cauldrons MANUALLY every 30 seconds, and there is no way to automate it in 1.15 vanilla afaik 2. they smelt a tiny bit quicker (afaik ) than furnaces and only gives you a lava bucket of fuel/fuel rod. which do you think would be better: a set of 8 furnaces, with potentially an automated system that smelts roughly 1 item per 3.75 seconds (30/8) costs 64 cobble, and maybe some hoppers if you want to automate the system and a bit of fuel (lava prob) or a single nuclear reactor that smelts as much as a lava bucket, and potentially is a bit quicker. probably is maybe 6 seconds and costs a nether star, 36 diamonds, only mentioning the expensive stuff.(edited)

sure, a nuclear reactor may LOOK cool, but it's not very effective

AND, with the punishment of not maintaining them, you get irradiation and a explosion"

The issue is currently being managed by Vohki and the developers of NuclearMC.
