This is because we used "OBI:has specified input some atomic nucleus" axiom on this class. Has specified input, as defined by OBI, has domains both process and planned process and the interpretation of multiple domains by OWL is the intersection of both classes. Hence, domain on this relation must be both process and planned process.

We can switch to "RO:has input".
