The Unit is exiting an outage with the plant at 345°F Tcold. During the outage, AFA-P01 was torn down for maintenance. A new governor assembly was installed due to older one having excessive tolerances. AFA-P01 is aligned and ready. All maintenance activities have been completed as have all applicable Surveillance Requirements, with the exception of SRs 3.7.5.2, 3.7.5.3, and 3.7.5.4. These have not been completed due to the fact that testing can only be accomplished once temperature reaches 532°F. Based on this, AFA-P01 is…

A. not operable, but functional.
B. operable until Mode 3 entry.
C. operable.
D. functional only, until tested at NOP/NOT.
