UNAVAILABILITY OF TSC VENTILATION SYSTEM DUE TO SCHEDULED MAINTENANCE
"At 0300 EST on Thursday, January 3, 2013, the DC Cook Nuclear Plant (CNP) Technical Support Center (TSC) air conditioning and charcoal filtration systems will be removed from service for scheduled maintenance.
"Under certain accident conditions the TSC may become unavailable due to the inability of the air conditioning and charcoal filtration systems to maintain a habitable atmosphere. Compensatory measures exist to relocate TSC personnel to the unaffected unit's control room if necessary.
"TSC ventilation system maintenance and post maintenance testing is scheduled to be completed by 2200 EST on January 3, 2013.
"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 the loss of an emergency response facility."
* * * UPDATE FROM GREGORY KANDA TO S. SANDIN ON 1/3/13 AT 2202 EST * * *
"The TSC ventilation system maintenance and testing was completed satisfactorily and the system was restored to service at 2115 EST on 1/3/13.
"The licensee has notified the NRC Resident Inspector."
Notified R3DO (Skokowski).

COMMERCIAL GRADE DEDICATION PROGRAM DEGRADED
"WBN [Watts Bar Nuclear] Unit 2 (under construction) has determined that certain equipment components have been installed that may not meet the requirements of the commercial grade dedication process. This condition has the potential to create a substantial safety hazard had it remained uncorrected. Evaluations are being performed to determine if the installed equipment would have still performed their safety functions. No specific cases of a substantial safety hazard have been found to date, but until evaluations are completed, the safety significance of this condition remains indeterminate. Therefore, this condition is conservatively being reported by WBN Unit 2 under 10 CFR 50.55(e)."
This programmatic issue encompasses approximately 500 evaluations.
The licensee will contact the NRC Resident Inspector.

LOSS OF ERDS CAPABILITY
"At 0930 [CST] on January 03, 2013 NextEra Energy Duane Arnold discovered that the Emergency Response Data System (ERDS) was no longer capable of transmitting plant data to the NRC. The loss of ERDS is reportable per 50.72(b)(3)(xiii).
"At 1151 [CST] on January 03, 2013 Information Management personnel restored ERDS to working status.
"The NRC Resident [Inspector] has been notified."
The licensee has the cause under investigation.
* * * UPDATE AT 2136 EST ON 01/03/13 FROM STEPHEN SPEIRS TO S. SANDIN * * *
"At 1725 [CST] on January 03, 2013 NextEra Energy Duane Arnold experienced a four minute interruption of the Emergency Response Data System (ERDS). During this time, ERDS was not capable of transmitting plant data to the NRC. The loss of ERDS is reportable per 10 CFR 50.72(b)(3)(xiii).
"The interruption of ERDS is related to a previous problem with the system reported under EN #48648. Troubleshooting of ERDS continues to ensure long-term reliability. Additional interruptions of ERDS are possible during this troubleshooting, and a follow-up notification will be made when ERDS reliability is assured."
The licensee informed the NRC Resident Inspector. Notified R3DO (Skokowski), ERDS Group and CAT Group via email.
* * * UPDATE FROM ROB SPADING TO CHARLES TEAL ON 1/28/13 AT 1436 EST * * *
Maintenance is complete on the ERDS system. It was tested satisfactorily on 01/15/13 at 1130 CST and returned to fully functional status.
The NRC Resident Inspector has been informed. Notified R3DO (Stone), ERDS Group and CAT Group via email.

LOSS OF SAFTEY PARAMETER DISPLAY SYSTEM (SPDS)
"On 01/03/13 at 0604 CST, the Wolf Creek Generating Station Nuclear Plant Information System (NPIS) computer was removed from service for scheduled maintenance.
"The NPIS computer being removed from service results in a loss of functionality of the SPDS. Due to SPDS being lost for longer than a short period of time, Wolf Creek Nuclear Operating Corporation is making this ENS notification pursuant to the criteria of 10 CFR 50.72(b)(3)(xiii). There was no other loss of emergency assessment capability concurrent with the ongoing loss of SPDS. When the equipment was removed from service, plant personnel entered the appropriate Off-Normal procedure and obtained local readings for the equipment that is normally monitored by SPDS and NPIS during the loss of the plant computer.
"NPIS computer was restored to service and declared functional at 1541 CST. The return of the NPIS computer to a functional condition restored the SPDS assessment capability function.
"The licensee notified the NRC Resident Inspector."
