Boration of the four reactor coolant system (RCS) cold leg injection lines was in progress using High Pressure Safety Injection pump 'A'. "During this activity, 'SI CHK VLV Leak Pressure Hi' alarms were received at 0828 [MST]. The 'A' and 'B' Low Pressure Safety Injection (LPSI) subsystems were declared inoperable because the pressure downstream of the motor operated LPSI injection valves was above 1525 psia. This elevated pressure potentially impacts the ability of the LPSI RCS loop injection valves to open. The high differential pressure may exceed the capability of the motor operator. All four injection line pressures were found above 1525 psia and LCO 3.0.3 was entered due to both trains of LPSI being inoperable. At 0839 [MST], pressure in the 'A' train injection lines was lowered below 1525 psia and 'A' LPSI subsystem was declared operable and LCO 3.0.3 was exited. At 0842 [MST], pressure was reduced below 1525 psia on the 'B' train injection lines and the 'B' LPSI subsystem was declared operable and LCO 3.5.3 condition A was exited. "This call is being made to report a condition that could have prevented the fulfillment of a safety function required to mitigate the consequences of an accident and unanalyzed condition that existed for 11 minutes while both LPSI subsystems were inoperable. "The NRC Resident Inspector has been notified." * * * RETRACTION RECEIVED FROM DANIEL HAUTALA TO CHARLES TEAL AT 1546 EST ON 12/15/11 * * * "The following event description is based on information currently available. If through subsequent reviews of this event, additional information is identified that is pertinent to this event or alters the information being provided at this time, a follow-up notification will be made via ENS or under the reporting requirements of 10CFR50.73. "This notification is a retraction of ENS 47459 which was made by Arizona Public Service to report a condition that could have prevented the fulfillment of a safety function required to mitigate the consequences of an accident and an unanalyzed condition that existed for 11 minutes while both LPSI subsystems were declared inoperable when pressure downstream of the motor operated injection valves for safety injection subsystem were declared inoperable. An engineering review of the motor operated valves thrust and torque calculations determined that the affected valves would have been fully capable of performing their intended safety function at the time of the pressure excursion. "The NRC Resident Inspector has been notified of this retraction." | Power Reactor | Event Number: 47499 | Facility: TURKEY POINT Region: 2 State: FL Unit: [3] [4] [ ] RX Type: [3] W-3-LP,[4] W-3-LP NRC Notified By: ROBERT STRUSINSKI HQ OPS Officer: MARK ABRAMOVITZ | Notification Date: 12/06/2011 Notification Time: 09:51 [ET] Event Date: 12/06/2011 Event Time: 09:30 [EST] Last Update Date: 12/15/2011 | Emergency Class: NON EMERGENCY 10 CFR Section: 50.72(b)(3)(xiii) - LOSS COMM/ASMT/RESPONSE | Person (Organization): BINOY DESAI (R2DO) | Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | 3 | N | Y | 100 | Power Operation | 100 | Power Operation | 4 | N | Y | 100 | Power Operation | 100 | Power Operation | Event Text TECHNICAL SUPPORT CENTER NON-FUNCTIONAL DUE TO PLANNED MAINTENANCE "Between December 6, 2011 and January 13, 2012, a sequence of activities are planned that will render the Technical Support Center (TSC) non-functional at times by removing the emergency ventilation system from service. These activities are being performed in support of planned preventive maintenance and extended power uprate facility upgrades.

The ARSO explained that the truck was not carrying any materials from the Nuclear Medicine Department or decay room and she knew of no reason that it would be radioactive. She provided the name and number for the CHP at Truckee. "The NRCP contacted the CHP and were told that they had surveyed the truck with a Ludlum meter and measured .400 millirem per hour (or 400 microR/hour) outside the trailer. The CHP said that their protocols dictate that anything above three times background is treated as a hazmat incident and must have proper packaging and manifest. They had not run an identification spectrum on the truck. They had no capability to unload a trailer on site for further investigation. They were holding the vehicle pending instructions from their departmental radiation specialist and agreed to call [the NRCP] when they had a decision. "The Aramark (linen service) representative confirmed that the vehicle in question was a tractor trailer and was carrying only linen from Renown. "At approximately 1545 PST, the CHP called and indicated that they had released the trailer with orders to return to Renown Medical Center. They were unable to identify the radioisotope present and the dose rate reading was now .100 millirem per hour (100 micro R/hr). "The NRCP Incident Response Supervisor arrived at Renown Medical center at approximately 1645 PST, shortly after the truck, and met with Renown staff. After conducting a radiation survey on the outside of the truck, he determined the general location of the high radiation and identified Technetium-99m (Tc-99m) as a suspected isotope. Linens are transported in large plastic bins, which were removed with a pallet jack, by the staff at Renown. When the radioactive bin was identified, it was segregated, a thorough survey was done and the radioisotope was positively identified as Tc-99m. The bin was placed in Renown's decay room where it will remain for 2 to10 days until the Tc-99m decays. "The most likely cause of this contamination was that a recently treated patient soiled the sheets and the possibility of radioactive contamination was not recognized by floor staff. Linens are not routinely screened for radiation. Aramark recently began transporting linens to Sacramento, rather than processing locally, so they are now subject to inspection upon entering California. The RCP will assist Renown with some procedure changes that will minimize the chances of this happening in the future. "Dose rate readings were one order of magnitude lower than what CHP reported. It is unknown why CHP was unable to obtain an accurate identification of the isotope. "Radiation readings: RadEye - Background 6 uR/hr; at bin 48 uR/hr; Ortec MicroDetective - Background 65 counts per second; at bin 1800 counts per second; Renown 451P Ion Chamber - Background 6 uR/hr; at bin 52 uR/hr; Ludlum 14c with pancake G-M detector - at bin 1800 counts per minute."

The RSO reported there were 4 fixed nuclear gauges on drums in the area of the fire. The gauges were Ohmart-Vega Model SH1G-1 and each contained a 300 milliCurie Cesium-137 source. Two gauges were directly in the fire and were damaged. The other two gauges were shielded from the fire by the drum they were mounted on and it has not yet been determined if they sustained any damage. The area was barricaded to prevent entry due to unsafe conditions caused by the fire (i.e. structural damage that has to be assessed, heat, ash/hydrocarbons). There were no radiation levels above background found during initial surveys from the barricade line and subsequent surveys conducted under the drums on the ground level and second level (areas where people will begin working). Higher levels will be surveyed prior to entry. The licensee has made arrangements with Ohmart-Vega for service to remove all 4 gauges once the area is safe. "Gauge and Source Information: Gauges: All Ohmart-Vega Model SH1G-1 Serial numbers:13543162, 13543163, 13543164 (in fire), 13543165 (in fire) Sources: Cesium-137, 300 milliCuries each, SN same as gauge Gauges installed March, 2010.

The flight originated on Marine Corps Air Station Miramar. During the flight the helicopter flew over the pacific ocean then to and over Camp Pendleton before returning to Miramar. An investigation into the event is ongoing. The results of the investigation will determine what actions are taken to recover the source. THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source | |
