| Event Text AGREEMENT STATE REPORT - OVEREXPOSURE TO RADIOGRAPHER WHEN CAMERA SOURCE BECAME DISCONNECTED
The following information was received by facsimile:
"On March 24, 2012, the licensee notified the Agency that it one of its radiography teams had experienced a disconnect of a 65 curie iridium-192 on a QSA Delta 880 radiography camera at a temporary work site in Pasadena, Texas. The crank out drive cable had broken and the source had completely disconnected. After an authorized individual performed the source retrieval, the licensee's RSO learned that the radiographer trainer disconnected the source tube from the camera and had carried the source tube around his neck while he climbed down the ladder of the scaffold. The source was in the tube at this time, but it is uncertain at this time the source's location within the tube. When the radiographer trainer reached the platform he removed the source tube from his neck. The licensee's initial dose estimates for the radiographer trainer are a whole body dose of at least 56 rem and an extremity limit that may exceed 100 rem. The radiographer's film badge is being sent for immediate reading. The licensee is conducting an investigation.
"NOTE: During the licensee's initial phone call to the Agency, the Agency understood the whole body dose estimate to be 6 rem and considered the event to be a 24-hour report (the Agency did report to the NRC HOO within 24 hours). However, when the Agency received the written initial report this morning, March 26, 2012, it was discovered that the estimate is 56 rem, which requires immediate notification. This report is being submitted to update and upgrade the event. More information will be provided as it is obtained.
The State also corrected the source strength to 65 curie Ir-192 source. REAC/TS was notified on 03/26/12 and the licensee has made contact with them.

"On March 27, 2012, Cooper Nuclear Station was informed by the National Weather Service that the Shubert NOAA Transmitter will be down for maintenance starting at 1130 on March 28, 2012 with maintenance lasting until approximately 1400 on March 28, 2012. This affects the tone alert radios Cooper Nuclear Station provides to members of the public to notify them of an emergency condition. This is considered to be a major loss of the Public Prompt Notification System capability, and is reportable under 10CFR50.72(b)(3)(xiii).
"State authorities and local county authorities within the 10 mile EPZ have been notified of the condition of the NOAA Transmitter and the effect on the tone alert radios and will utilize Local Route Notification (backup notification method). The licensee has notified the NRC Resident Inspector of the condition."

"At 1503 hours EDT on March 28, 2012, with the unit in Mode 1 at 55% power, an automatic reactor trip occurred. The reactor trip was the result of a turbine trip from a 'B' Steam Generator Hi Level. All Reactor Coolant Pumps (RCP) remained running.
"The Auxiliary Feeedwater (AFW) System automatically actuated due to both main feedwater pump breakers opening from a valid feedwater isolation signal. Steam Generator Levels were then controlled by Auxiliary Feedwater pumps. Steam Generator Blowdown was automatically isolated with the AFW actuation. The RCS Code Safety valves, Pressurizer Power Operated Relief Valves (PORVs), Steam Generator PORVs or the Main Steam Safety valves (MSSVs) did not open during the event. All control rods fully inserted following the reactor trip.
"The normal post-trip electrical lineup is providing power to the plant and the electrical system is stable. Decay heat is being removed via the condenser. The reactor is currently in Mode 3 and stable.
"There were no radiological consequences or releases as a result of this event.
"The cause of the Steam Generator Hi Level is under investigation.
"The Resident NRC Inspector has been informed." |

"On 3/28/2012, Xcel Energy Personnel determined that approximately 50% of the Amertap balls recently used were not recovered. A survey of the Mississippi River bank downstream of the plant by site personnel recovered an additional 3 Amertap balls, indicating that the balls were not released to the river. Monticello Nuclear Generating Plant (MNGP) is required to report to the Minnesota Pollution Control Agency (MPCA) when greater than 20% (1 .5 barrels or approximately 7,500) of the Amertap balls are not recovered. This is based on an agreement with the MPCA dated September 12, 2008. The MPCA was notified at 1648 CDT on 3/28/12."

"At 1500 on March 28, 2012, Callaway Plant personnel discovered that the installation of a modification on the two 'B' train containment cooler units had inadvertently introduced a potential failure mechanism to the 'B' train containment coolers. Specifically, with the containment cooling fans initially in fast-speed operation, combined with certain initial plant conditions, thermal overload tripping of the coolers could occur.
"In such an event, during some postulated accidents, slow-speed restart of the containment coolers by the Load Shedding and Emergency Load Sequencing system could be prevented. As a result, the 'B' train containment coolers could be rendered unavailable for a portion of a postulated accident. Thus, the safety function of the 'B' train containment cooling fans cannot be assured when this degraded equipment condition is present and the containment cooling fans are run in fast-speed operation.
"This condition existed for the 'B' train containment cooling units since they were restored to service from maintenance at 0400 on March 15, 2012.
"Upon identification of this condition, the 'B' train containment cooling fans were switched from fast-speed to slow-speed operation and restored to operable status at 1515. This action precludes this degraded equipment condition from adversely affecting containment cooling fan function during an accident.
"Concurrent with this condition, the opposite train of containment coolers was removed from service for scheduled maintenance at 0505 on March 27, 2012. As a result, from 0505 on March 27, 2012 until 1515 on March 28, 2012, the safety function of the containment cooling system could not be assured for certain postulated accident conditions.

"On March 14, 2012, it was determined that in the event of an Appendix R fire, fire damage to cables in Fire Area 2-4, 3-3, or 25-1 could cause a Residual Heat Removal Service Water System (RHRSW) pump to spuriously start. This unanalyzed condition was originally determined to be not reportable. However, during subsequent review on March 28, 2012, this condition was determined to be reportable since the additional load from the spurious start of the RHRSW pump on the associated Emergency Diesel Generator (EDG) could result in the design maximum loading of the EDG being exceeded. As a result of the EDG maximum loading being exceeded, the EDG credited in the Appendix R fire analysis to supply required Appendix R safe shutdown loads could fail. The issue has significant safety impact since the capability to supply power to the Appendix R safe shutdown equipment for the credited EDG is necessary to provide adequate core cooling and decay heat removal during performance of the Browns Ferry Nuclear Plant Safe Shutdown Instructions in an Appendix R fire event."

"On 3/24/12 at 1810 hrs EDT, a four inch sewage line in the turbine building failed. This allowed sanitary wastewater to spill into the turbine building basement. An estimated 100 gallon entered into trench drains and then to the station sump which discharges into the conventional wastewater system. This conventional wastewater system is discharged to the Keowee River from NPDES [National Pollutant Discharge Elimination System] outfall 002. The discharge of outfall 002 is into the Keowee River below the Keowee River Hydro Station. The normal discharge path for sanitary wastewater is to the City of Seneca. South Carolina DHEC [Department of Health and Environmental Control] was notified of the spill on 3/24/12 at 2259 hrs EDT. After further review, this was determined to be reportable under 10CFR50.72(b)(2)(xi)."
This event was determined to be reportable at 2150 EDT on 3/28/2012. The event was entered into the corrective action program. There was no impact on plant operations and the cleanup has been completed. The licensee notified the NRC Resident Inspector. |
