"On April 11, 2013, at 1300 hours, during the performance of On-Line Automatic Depressurization System (ADS) Blowdown Logic Testing, two poor wiring connections were identified (the electrical leads were not properly compressed at their termination point). The electrical leads are associated with the B and C ADS valves. Quad Cities has five ADS valves which can be used to depressurize the Reactor Pressure Vessel under accident conditions. While the solenoids of these valves were actuated successfully during the recent Unit 1 refueling outage (which ended on April 8, 2013), the less than optimum configuration could have prevented the valves from actuating under design basis conditions. The degraded wiring for both valves was restored at 1741 hours [CDT].
"Given the potential impact on the ADS depressurization function, this event is reportable under 50.72(b)(3)(v)(D) as an event or condition that could have prevented the fulfillment of a safety function."
The licensee notified the NRC Resident Inspector.
* * * RETRACTION ON 6/3/13 AT 1138 EDT FROM FRED SWIHART TO DONG PARK * * *
"The purpose of this notification is to retract the ENS Report made on April 11, 2013, at 2110 EDT (ENS Report # 48916).
"Further evaluation performed by Quad Cities Station confirms the Unit 1, 3B and 3C Automatic Depressurization System (ADS) valves would have performed their safety functions when required. Based on this subsequent evaluation, ENS Report # 48916 is being retracted.
"Note: On April 11, 2013, at 1741 CDT the degraded wiring for the Unit 1, 3B and 3C ADS valves was repaired and both valves were returned to operable status."
The licensee notified the NRC Resident Inspector.

| Event Text UNPLANNED MEDICAL TREATMENT
"An employee reported to the dispensary this morning with a finger laceration [at approximately] 1025 CDT. The plant nurse administered first aid and decided to send the employee to an offsite medical facility. A whole body survey of the employee in his plant clothing was performed; the maximum amount of contamination was present on his right boot, 55,039 dpm/100 cm2. Prior to leaving the Restricted Area, the employee removed all plant clothing, changed into his personal clothing, and was re-surveyed. The employee was free of contamination upon release."
