It's not obvious how to translate this figure into a standalone plant cost. The COB study is quoting the acquisition cost premium of a nuclear ship over a non-nuclear ship. I believe that estimate is the premium for taking a non-nuclear design and adding a nuclear reactor to it, so it does not include a lot of plant infrastructure that is part of the cost of civilian power stations. Also I would think the requirements for the containment structure and safety systems would be significantly different.
