PH MONITORING PROBE EFFLUENT BYPASSES THE WASTE HOLDUP POND
"As part of the on going investigation of the final holdup pond (NRC Notification #43958), McGuire has identified a discharge path from the pH monitoring and adjustment system that has existed since plant startup. This discharge path has been secured. The North Carolina Department of Environmental and Natural Resources will be notified."
The effluent from the pH monitoring probe had been routed to a pit which drains into the river i.e. bypassing the holdup pond.
The licensee notified the NRC Resident Inspector.

CONTROL ROD POSITION DEVIATION
"While withdrawing shutdown bank rods in preparation for a North Anna Unit 2 startup, a Rod Control system Urgent Failure alarm was received in the main control room. Further investigation revealed group step counters for Shutdown Bank 'A' deviated by 3 steps from demand. TRM 3.1.3 was entered and the Reactor Trip breakers were opened within the 15 minute requirement."
The licensee notified the NRC Resident Inspector.
