"On November 2, 2014 EST, the bus providing power to the Health Physics emergency HVAC system for climate control tripped unexpectedly and has been out of service for greater than 30 minutes. The Health Physics emergency HVAC system for climate control is required for functionality of the Operations Support Center (OSC), which is a required emergency response facility (ERF). Actions to determine the cause of loss of 1R24-S030 Load Center and to return ERF to functional status are in progress with high priority. In the interim, the backup OSC remains fully functional and capable of providing the required support as defined in the Hatch Emergency Plan and emergency implementing procedures.
"This notification is being made in accordance with the plant's Technical Requirements Manual Specifications to make the notification within 8 hours in accordance with 10 CFR 50.72 (b)(3)(xiii) due to the unplanned loss of an emergency response facility. An update will be provided once the OSC has been restored to normal operation."
The licensee notified the NRC Resident Inspector.
* * * UPDATE FROM JOHN MITCHELL TO HOWIE CROUCH AT 2126 EST ON 11/2/14 * * *
Power was restored to the 1R24-S030 Load Center at 1955 EST. At 2038 EST, power to the Health Physics emergency HVAC system was restored. The OSC was returned to service at 2120 EST.
The licensee has notified the NRC Resident Inspector. Notified R2DO (Blamey).
* * * RETRACTION FROM KENNY HUNTER TO DANIEL MILLS AT 1641 EST on 12/31/14 * * *
"In accordance with NUREG 1022, Revision 3, Supplement 1, the NRC endorsed NEI 13-01, 'Reportable Action Levels for Loss of Emergency Preparedness Capabilities,' such that 'if a licensee has a 'backup ERF' that is capable of performing the functions of the primary facility, the licensee's emergency assessment capability is not significantly impaired if the primary facility is not available.' Based on this information this condition is not reportable.
"Although NUREG 1022, Rev. 3, Supplement 1 did not require an event notification report to be made, an initial notification was generated based on requirements within licensee control documents. These documents have been updated to reflect the guidance provided in the supplement to NUREG 1022. This report is therefore being retracted in accordance with NUREG 1022, Rev. 3, Supplement 1 since a backup ERF remained fully functional and capable of providing the required support during the event.
"The licensee notified the NRC Resident Inspector."

| Event Text TEXAS AGREEMENT STATE REPORT - SOURCE DISCONNECTED ON A RADIOGRAPHY CAMERA
The following information was obtained from the State of Texas via email:
"On December 23, 2014, the licensee notified the Agency [Texas Department of State Health Services] that one of its radiography crews, who was performing radiographic operations at one of its licensed sites in Houston, Texas, had experienced a source disconnect.
"After completing an exposure, the radiographers cranked the 79 curie cobalt-60 source back into the SPEC300 exposure device. However, as they started to walk toward the end of the guide tube, their survey meter and alarming rate meters indicated the source was still in the guide tube. They moved their boundaries back, secured the area, and called their supervisor. The licensee's radiation safety officer and two employees who are approved on the license for source retrieval responded to the site. They found that the source assembly (pigtail) cable had broken a couple of inches back from the source. The source was retrieved from the guide tube and placed back inside the exposure device. A survey confirmed the source was in the shielded position. The licensee is sending the exposure device and all associated equipment from this event to the manufacturer for evaluation. No member of the public received any exposure and there were no overexposures to any of the radiographers or source retrieval team.
"An investigation into this event is ongoing. More information will be provided in accordance with SA-300 as it is obtained."

"At 1105 PST, plant personnel identified through-wall seepage in a Diablo Canyon Power Plant Unit 1 socket weld inside containment that provides a flow path to a relief valve protecting a common portion of both trains of the Residual Heat Removal (RHR) System. The as-found condition falls under the requirements of the ASME acceptance criteria. Unit 1 was already in Mode 3, or offline, due to a planned maintenance outage. PG&E accordingly declared both Unit 1 trains of RHR inoperable and has initiated a transition from Mode 3 to Mode 4 in accordance with requirements of Technical Specification 3.0.3.

"During [surveillance] checks of Control Room doors, a boundary door did not latch after being accessed until the door was opened and closed. This is being reported as it could have prevented the fulfillment of a safety function to mitigate the consequences of an accident per 10CFR50.72(b)(3)(v)(D). The door is currently closed and latched. The door was in this condition for between 5 and 10 seconds."
