LOSS OF EMERGENCY PREPAREDNESS CAPABILITIES DUE TO UNIT 1 PPC REPLACEMENT
"The Unit 1 DC Cook Nuclear Plant (CNP) Plant Process Computer (PPC) will be removed from service on Monday, August 19, 2013 at 0900 EDT to support planned replacement. The Unit 1 PPC, including the Emergency Response Data System (ERDS), will be unavailable to the NRC Operations Center. Planned replacement also affects the Safety Parameter Display System (SPDS), the Real Time Data Repository (RDR), and PPC data to Emergency Response Facilities at CNP. Safety system annunciators and indications in the control room remain available.
"The scheduled replacement, returning of equipment to service and post maintenance testing is expected to be completed by 2000 EDT on Saturday, September 7, 2013.
"Compensatory measures exist within the DC Cook emergency response procedures to provide plant data via the Emergency Notification System to the NRC Operations Center until the ERDS can be returned to service.
"The licensee has notified the NRC Resident Inspector.
"This notification is being made in accordance with 10 CFR 50.72 (b)(3)(xiii) due to any event that results in a major loss of emergency assessment capability, offsite response capability, or offsite communications capability (e.g., significant portion of control room indication, Emergency Notification System, or offsite notification system)."
* * * UPDATE AT 1228 EDT ON 10/15/13 FROM BOWMAN TO HUFFMAN * * *
The Unit 1 DC Cook Nuclear Plant (CNP) Plant Process Computer (PPC) was restored to service on Tuesday, October 1, 2013 at 1649 EDT following the planned replacement of the PPC. The Unit 1 PPC is fully functional, including the Emergency Response Data System (ERDS), which is available to the NRC Operations Center. This also restores the Safety Parameter Display System (SPDS), the Real Time Data Repository (RDR), and PPC data to Emergency Response Facilities at CNP.
The licensee has notified the NRC Resident Inspector. R3DO (Duncan) notified.

INCREASING BACKGROUND NOISE IN STACK RADIATION MONITOR RENDERS IT NON-FUNCTIONAL
"At 1013 hours PDT on August 19, 2013 the Reactor Building Stack Radiation Monitor High Range Detector was declared nonfunctional due to increasing background noise. The Reactor Building Stack Radiation Monitor Intermediate Range Detector remains functional and shows no increase in effluent radioactivity.
"To compensate for the loss of assessment capability due to the nonfunctioning radiation monitoring equipment, an additional Health Physics (HP) Technician trained to acquire offsite dose assessment information on offsite releases will be available. The additional personnel will be pre-staged in support of the Radiation Monitoring System outage and will be mobilized in accordance with guidance in the compensatory measure instructions.
"This event is being reported as a loss of emergency assessment capability in accordance with 10 CFR 50.72(b)(3)(xiii). A follow-up notification will be made when the equipment has been returned to service.
"The licensee will notify the NRC Resident Inspector."
* * * UPDATE FROM MICHAEL STODICK TO PETE SNYDER AT 2028 EDT ON 8/19/13 * * *
"Initial investigation into the cause of the malfunction of the Reactor Building Stack Radiation Monitor High Range Detector revealed that the condition also affected the Reactor Building Stack Radiation Monitor Intermediate Range Detector. Therefore, this monitor has also been declared non-functional as of 1633 hours PDT on August 19, 2013. Compensatory measures remain in effect to provide emergency response capability for assessing and monitoring actual or potential offsite consequences of a radiological release through this pathway. Corrective actions are being pursued to restore the affected monitors to functional status."
The licensee notified the NRC Resident Inspector. Notified R4DO (Werner).
* * * UPDATE FROM MOT HEDGES TO HOWIE CROUCH AT 1236 EDT ON 8/21/13 * * *
"The cause of the increased background noise for the Reactor Building Stack Radiation Monitor-High Range was due to failing cooling components for the instrumentation, resulting in increased electronic background noise in the instrumentation. There has been no change in the radiation levels at the plant.
"The NRC Resident Inspector has been notified."
Notified R4DO (Werner).
* * * UPDATE FROM MOT HEDGES TO MARK ABRAMOVITZ ON 8/22/2013 AT 1630 EDT * * *
"Repairs have been completed and both the Intermediate and High Range Reactor Building Stack Radiation Monitors have been returned to service. The licensee has notified the NRC Resident Inspector."
