Upon subsequent review of the Material Safety Data Sheet associated with the fluid that leaked from the vehicle, it was determined that the fluid was not a hazardous substance as defined by the State of New Jersey (Appendix A of N.J.A.C. 7:1E). Additionally, it was determined that the fluid did not reach surface water. Based on this information, the New Jersey Department of Environmental Protection (NJDEP) was notified that the fluid that leaked from the vehicle did not reach surface water and was not a hazardous substance. The NJDEP notification was updated for the record. For the above reasons, the 4 hour non-emergency ENS notification made under EN # 49850 is hereby retracted The NRC Resident Inspector has been informed. Notified R1DO (DeFrancisco).

At 0329 EDT, Oyster Creek experienced a loss of offsite power. As a result of the loss of offsite power, the unit automatically scrammed from 100% with all control rods fully inserting and all safety systems functioning as required. Both Emergency Diesel Generators automatically started and are carrying loads on the safety buses. At 0341 EDT, Oyster Creek declared an Unusual Event based on a loss of offsite power for greater than 15 minutes. The unit is stable in Hot Shutdown with decay heat removal via the Isolation Condenser. The cause of the loss of offsite power is currently under investigation by JCP&L. The licensee notified the State and local agencies, as well as the NRC Resident Inspector. The licensee will be making a press release.

• * * UPDATE ON 7/23/12 AT 0625 EDT FROM ROBERT SALES TO DONG PARK * * *

Oyster Creek has terminated from the loss of offsite power Unusual Event (at 0538 EDT). All safety systems functioned as expected for this event. The licensee has notified the NRC Resident Inspector. Notified R1DO (Dimitriadis), NRR EO (Nieh), IRD (Gott), DHS SWO, FEMA, and DHS NICC.

• * * UPDATE ON 7/23/12 AT 1205 EDT FROM ANDREW ZUCHOWSKI TO VINCE KLCO * * *

As a result of the loss of offsite power, both Emergency Diesel Generators automatically started and carried loads on the safety buses, as required. Offsite power was returned to service at 0457 EDT and both Emergency Diesel Generators were secured at 0520 EDT. Per 50.72(b)(3)(iv)(A), Oyster Creek is reporting any event or condition that results in valid actuation of an Emergency AC electrical power system. Additionally, the Reactor Building (Secondary Containment) differential pressure indicated positive 0.25 inches W.G. at approximately 0357 EDT. Reactor Building differential pressure indication returned to normal at 0434 EDT. Oyster Creek is currently investigating the cause of the positive Reactor Building pressure indication. Per 50.72(b)(3)(v)(C), Oyster Creek is reporting an event that could have prevented the fulfillment of the safety function of a system needed to control the release of radioactive material. The licensee notified the NRC Resident Inspector. Notified R1DO (Gray).

• * * UPDATE AT 0914 EDT ON 9/12/12 FROM ERIC SWAIN TO HUFFMAN * * *

As a result of further investigation it was found that the Reactor Building Differential Pressure issue was an indication issue only and not indicative of a loss of the secondary containment barrier. The positive indication was caused by a degradation of instrument air pressure to the instrument used to generate the differential pressure indication. The degradation of instrument air pressure was an expected condition caused by the loss of offsite power. Alternate indication, not affected by instrument air pressure, was available throughout the event. The alternate indication read negative 0.4 Inches water gauge throughout the event. Based on this information Oyster Creek is retracting the portion of this report that was reported per 50.72(b)(3)(v)(C), an event that could have prevented the fulfillment of the safety function of a system needed to control the release of radioactive material. The licensee has notified the NRC Resident Inspector. R1DO (Newport) notified.

Oyster Creek Nuclear Generating Station notified the New Jersey Department of Environmental Protection of a leak of water containing tritium from an underground condensate transfer pipe at the turbine building penetration of less than 20 gpm and concentration of approximately 10 million picocuries/milliliter. The leaking water is being pumped to storage drums and a plan is being developed to replace the six-inch condensate transfer piping which penetrates the turbine building inside a 42 Inch long sixteen inch diameter penetration sleeve. Previously, water was observed coming from the sleeve into the turbine building where it was draining to a sump. The leak coming out of the turbine building was uncovered during excavation to determine if the condensate was leaking to the soil. The licensee notified the NRC Resident Inspector.

• * * UPDATE PROVIDED BY CALVIN TAYLOR TO JASON KOZAL AT 0907 ON 08/26/09 * * *

The licensee corrected the reported concentration to 10 million picocuries/liter. Additionally, after closer examination the leak rate was determined to be approximately 5 GPM vice the initially reported less than 20 GPM. The licensee will be issuing a press release. Notified the R1DO (White).

At 98% power, a reactor scram occurred due to a Main Transformer fault. The plant is currently stable in the Hot Shutdown Mode. Isolation Condensers initiated as part of this event are currently in Standby Mode. This event is reportable in accordance with 10CFR50.72(b)(2) and (b)(3) and the Station Reportability Manual section SAF 1.6 and SAF 1.7. The cause of the transformer fault is unknown and under investigation. There was no fire or explosion associated with the fault. All rods inserted during the scram. As a result of the transient, one electromatic relief valve lifted and subsequently reseated. There were no other isolations or safety equipment actuations during the transient. The station electrical system is in its normal shutdown lineup with offsite power available. Decay heat is being removed via the turbine bypass valves to the main condenser. Pressure is currently at 700 psi with water level being maintained at 160" via the main feed system. The licensee has notified the NRC Resident Inspector and will be notifying the State of New Jersey.

This is a NRC ENS 24 hr notification per Oyster Creek Environmental Tech Spec Section B 1.1.1 A. At 11:45 on 01/29/06 a total of 100 fish were spotted either dead or stressed in the discharge canal following a Reactor S/D (shutdown) that was completed at 22:22 on 01/28/06" R1DO (N. Perry) notified. The NRC Resident Inspector was notified of this event by the licensee. The state will be notified.

At 1145 EDT the Chemistry Tech sampled the Rad Waste Service water overboard line. The sample showed less than 0.02 milligrams per liter (mg/l) residual chloride. The Chemistry Tech adjusted up the chlorination rate. At 1315 a second sample yielded a result of 0.29 mg/l residual chloride. The tech immediately secured the Chloride system, and sampled the intake canal. The results were less than 0.02 mg/l residual chloride. Oyster Creek is monitoring for any environmental impact. The change in residual chloride may not correlate to the increase in chlorination rate, therefore sample error is possible and is under review. The licensee notified the NRC Resident Inspector.
