Still there is no re-fuelling station for the nuclear rods.
The reactors are going to be around the 200m mark, and are likely to have containers over them. That said, some lifeboats near that point would not be a bad idea.
For electronics, I am going to need more specifics. Same with why the bridge looks wrong.
Civilian ships like this have multiple smaller radars to provide redundancy for surface and weather tracking. The radar you've got on there is an early drawing of the Type 992 radar, which was an air search and target indication radar, not something you'd want on your ship. The radars you want are going to be small bar radars, and you will want several of them with backups near the bow and stern for extra coverage.
