Just watched a really good and incredibly informative video on this, https://youtube.com/watch?v=nt4rZgndOoE. From what is explained in the video is that this is mostly filing paperwork, they haven't verified their reactor works or that it's able to output power, let alone output more power than what is required to start and maintain a fusion reaction. So over all, a little exciting, but really nothing to get too excited about yet.
Edit: grammar fixes
