Your wording is awful by the way. If you meant, "why are my machines stoping working if i go to far away" then its because minecraft works in what are called chunks. Chunks are 8x8 blocks wide and go from beadrock to world height. Chunks are loaded and unloaded when players are nearby. If a chunk is unloaded by you going to far away then most machines and other things will stop working. they should resume when the chunk is loaded again. you can keep a chunk loaded by placing a dimensional or world anchor near by. In the case of a nuclear reactor the heat is still calculated if the chunk is unloaded but the cooling is not. So make sure you have a way to keep a chunk with a reactor in it loaded,otherwise KABOOM!!!
