Hi, I recently found NTM (1.7.10 version) and was super excited about it and how well it integrates with OC (Looking at wiki's page

Unfortunately, it seems that a significant portion of this support was lost in forks for 1.12.2.
According to the wiki's page, only the reactor is available.

Are there any plans to add the rest of the components?

RBMK Reactor and RBMK Crane have OC compatibility. If u want other machines feel free to make a pull request.
