REVISE the wording of the OMA from "Open IIP-500X to enable ASSS pneumatic instruments" to "Activate/enable Alternate Safe Shutdown System (ASSS) pneumatic instruments (Steam Generator level, Pressurizer pressure and level) at Fan House local control panel. Also enable ASSS source-range channel and Loop 21 and 22 hot (Th) and cold leg (Tc) temperature channels." Add "source range, and RCS hot and cold leg temperature" to the Affected Component(s) column, and add cables FDI-H27/08 and FDS-H30/08 for source range channels to the Associated Cables column.
To agree with the description of the OMA on Table RAI-08.1-3; these instruments were inadvertently omitted from the OMA and Affected Component(s) columns; the cables in the Associated Cables column included cables for all instruments having cables in Containment (pressurizer pressure channels only have sensing lines in Containment), but the cables for the source range channels were inadvertently omitted.
