AGREEMENT STATE REPORT- CONTAMINATION EVENT

The following information was received by facsimile:

"DRH [Tennessee Division of Radiological Health] was notified on 10/19/12 by the licensee that preliminary analytical results of a 30-gallon waste container of tritium contaminated waste oil and absorbents indicate approximately 8,600 curies of tritium. The container was manifested by the generator (SRS) [Savannah River Site] as containing 14.9 curies. Post sampling of this container, DSSI [Diversified Scientific Services, Inc.] had a controlled but elevated level of tritium contamination in the process room; this room is under negative ventilation. The room has been decontaminated back to normal processing levels. Contents of the container have been overpacked and placed in a safe state, [and] not a source of tritium contamination to the air or surface."

AGREEMENT STATE REPORT - LOST SOURCE

The licensee misplaced a static eliminator device containing 10 mCi of Po-210. The device model number is P-2021-8301; Serial number is A2HS590. The device was used to neutralize static charge on plastic parts prior to entering the paint process. The licensee considers the device as lost.

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.

RADIOGRAPHY SOURCE STUCK

"A drive cable designed for 25' controls was installed in a 35' control assembly. This resulted in 15' of usable drive cable to travel through the guide tube. The radiographers were using a guide tube and extension with a total length of 17' and were unaware that there was not enough drive cable to reach the source stop. The cable was run out past the stop, and could not be retracted.

"The exposure being taken at the time of the incident was a 6:00 shot on a 12" oil line. The line was 15' off the ground near an elevated platform. There was a 42" pipe running between the platform and the pipe being inspected. The exposure device was placed on the platform and an extension was added to the guide tube to route the source around the 42" pipe. The total length of the guide tube and extension was 16'11". The control cables were rerouted to take advantage of nearby shielding. The conduits were disconnected from the Pistol Grip Assembly exposing the drive cable. The source was then retracted into the fully shielded position by pulling the drive cable by hand.

"The entire inventory of control assemblies were inspected to ensure the proper drive cables are installed, as will new assemblies when they are initially received. Additionally, personnel qualified to repair control assemblies will be retrained with emphasis placed on ensuring proper length of drive cable is in place. Training will be documented and filed in personnel records.

AGREEMENT STATE REPORT - MEDICAL DOSAGE NOT DELIVERED AS PLANNED

A patient was being treated for a liver tumor and the dosage was delivered to the wrong lobe. The physician prescribed 17 mCi of Y-90 to the left lobe of the liver. The prescribing physician was not present during the dose administration procedure. The intervention radiologist examined a fluoroscope of the patient's liver and noted a larger tumor on the right lobe. The prescribed dosage was then delivered to the right lobe of the liver, not in accordance with the prescribed dosage plan. Patient examination detected no observable impact, and the physician is developing another dosage plan for the patient. The Iowa Department of Public Health will perform an onsite investigation.

A Medical Event may indicate potential problems in a medical facility's use of radioactive materials. It does not necessarily result in harm to the patient.

NOTICE OF UNUSUAL EVENT DECLARED DUE TO HIGH INTAKE STRUCTURE WATER LEVEL

At 1855 EDT on 10/29/2012, the licensee declared a Notice of Unusual Event (NOUE) per criteria HU4 for high water level in the station intake structure of greater than 4.5 feet. At the time of the notification, water level in the intake structure was approximate 4.8 feet and slowly rising. The cause of the increased water level was due to storm surge associated with Hurricane Sandy. No other station impacts were reported at the time. The licensee continues to monitor the intake levels and ocean tides.

The licensee has notified the NRC Resident Inspector and the State of New Jersey.

* * * UPDATE ON 10/29/2012 AT 2141 EDT FROM STEVE SERPE TO RYAN ALEXANDER * * *

At 2044 EDT on 10/29/2012, the licensee escalated its emergency declaration to an Alert per criteria HA4 for high water level in the station intake structure of greater than 6.0 feet. At the time of the notification, water level in the intake structure was approximately 6.6 feet. The site also experienced a loss of offsite power event concurrent with the additional water level increase. Both emergency diesel generators started and are supplying power to the emergency electrical busses. Shutdown cooling and spent fuel pool cooling have been restored. Reactor pressure vessel level is steady at 584.7 inches. Intake levels continues to rise slowly and the licensee is monitoring.

The licensee has notified the NRC Resident Inspector and the State of New Jersey.

Notified DHS SWO, FEMA Ops Center, USDA Ops Center, HHS Ops Center, DOE Ops Center, DHS NICC Watch Officer, EPA EOC, and NuclearSSA via e-mail.

* * * UPDATE on 10/30/12 at 0414 EDT FROM GILBERT DEVRIES TO RYAN ALEXANDER * * *

The licensee updated this report with an 8-hour non-emergency notification of emergency diesel generator auto-actuation due to the actual loss of off-site power event [which occurred at 2018 EDT on 10/29/2012]. This event caused a valid RPS actuation with automatic containment isolations that resulted in a temporary loss of shut-down cooling to the reactor. Shutdown cooling was subsequently restored with power provided by the emergency diesel generators.

The licensee has notified the NRC Resident Inspector. Notified R1DO (Caruso).

RPS ACTUATION WHILE CRITICAL DUE TO GENERATOR LOAD REJECT

On October 29, 2012 at 2100 EDT, Nine Mile Point Unit 1 experienced an automatic reactor scram due to a generator load reject. The cause of the load reject is currently under investigation. All control rods fully inserted and all plant systems responded per design following the scram.

Following the automatic scram, the High Pressure Coolant Injection (HPCI) System automatically initiated as expected. At Nine Mile Point Unit 1, a HPCI System actuation signal on low Reactor Pressure Vessel (RPV) level is normally received following a reactor scram, due to level shrink. HPCI is a flow control mode of the normal feedwater systems, and is not an Emergency Core Cooling System. At 2101 EDT, RPV level was restored above the HPCI System low level actuation set point and the HPCI System initiation signal was reset. Pressure control was established on the Turbine Bypass Valves, the preferred system. Three Electromatic Relief Valves actuated due to this scram and re-closed automatically.

Nine Mile Point Unit 1 is currently in Hot Shutdown, with reactor water level and pressure maintained within normal bands. Decay heat is being removed via steam to the main condenser using bypass valves. Both Reserve Station Transformers are in service and being supplied by their normal power sources. Both Emergency Diesel Generators are operable and in standby.

The unit is currently implementing post scram recovery procedures.

The licensee has notified the NRC Resident Inspector. Notified R1DO (Caruso).

AUTOMATIC RPS ACTUATION ON GENERATOR TRIP

"On October 29, 2012, at 2241EDT, the Reactor Protection System automatically actuated at 100% reactor power due to a direct electrical trip to the Unit 3 Main Turbine Generator. The generator trip resulted in a turbine/reactor trip. All control rods fully inserted on the reactor trip. All plant equipment responded normally to the unit trip. This is reportable under 10 CFR 50.72(b)(2)(iv)(B). The plant is stable in Mode 3 at this time.

"The Auxiliary Feedwater System actuated following the automatic trip as expected. This is reportable under 10 CFR 50.72(b)(3)(iv)(A). The Emergency Diesel Generators did not start as offsite power remained available and stable. The unit remains on offsite power and all electrical loads are stable. No primary or secondary relief valves lifted. The plant is in Hot Standby at normal operating temperature and pressure with decay heat removal using auxiliary feedwater to the steam generators and normal heat removal through the condenser via condenser steam
dumps. There was no radiation released.

"Indian Point Unit 2 was not affected by this event and remains at 100% power.

"A post trip investigation is in progress."

The licensee notified the NRC Resident Inspector. Notified R1DO (Caruso).

AUTOMATIC INITIATION OF EMERGENCY DIESEL GENERATOR DUE TO LOSS OF ONE OFF-SITE POWER SOURCE

"On October 29, 2012 at 2100 EDT, Nine Mile Point Unit 2 experienced an automatic initiation of the Division 1 Emergency Diesel Generator due to a loss of line 5. Line 5 is one of the 115KV offsite power sources. Line 5 was lost due to a lightening arrestor falling onto electrical components in the Scriba switchyard during high winds.

"During the electrical transient, Nine Mile Point Unit 2 also experienced a feedwater level control lockup, requiring manual control. No Emergency Core Cooling Systems actuated and feedwater level control was returned to automatic. Nine Mile Point Unit 2 remained at 100% power during the loss of line 5.

"The off-site power source, line 5, was restored on October 30, 2012 at 0326 EDT."

MANUAL REACTOR TRIP FROM 100% POWER

"This report if being made under the requirements of 10 CFR 50.72(b)(2)(iv)(B), Actuation of the Reactor Protection System While Critical, except preplanned, and under the requirements of 10 CFR 50.72(b)(3)(iv)(A), Valid Actuation of Listed System, except preplanned.

"Salem Unit 1 was operating at 100% reactor power when a loss of 4 condenser circulators required a manual reactor trip in accordance with station procedures. The cause of the 4 circulators being removed from service was due to a combination of high river level and detritus from Hurricane Sandy's transit.

"All control rods inserted. A subsequent loss of the 2 remaining circulators required transition of decay heat removal from condenser steam dumps to the 11-14 MS10s (atmospheric steam dump). Decay heat removal is from the 11/12 Aux Feed Pumps to all 4 steam generators via the 11-14 MS10s. 11/12/13 AFW pumps started due to low level on all steam generators due to shrink from full power operation (this is a normal response). All safety related equipment functioned as expected. No one has been injured. As an additional note, Hurricane Sandy had recently moved past artificial island. Salem Unit 1 is currently in Mode 3. Salem Unit 2 reactor is currently in its 2R19 refueling outage and is shutdown and defueled with no fuel movement in progress."

The licensee has notified the NRC Resident Inspector. Notified R1DO (Caruso).
