ROP Assessment- Significant ROP Inspection Findings (Reference TAB 5)

A Special Inspection was initiated when the licensee identified that the breakers for pressurizer heaters powered from the SSF could trip prematurely. As a result of the inspection, three potentially greater than Green findings were identified for failing to maintain design control of SSF components and failing to perform adequate operability evaluations.

Potential Discussion Topics (Reference TAB 6)

External Flood Action Plan An issue related to the potential impact that external flooding would have on the Oconee Nuclear Station is currently being addressed by both the licensee and NRC. The licensee has developed Interim Compensatory Measures (ICMs) to address the external flooding concerns and is working on permanent actions to ensure the station is not adversely affected by a potential external flooding scenario. A Confirmatory Action Letter (CAL) was issued on June 22, 2010, to confirm that the ICMs would remain in place until final modifications have been completed. The CAL also requested the licensee to provide a list of modifications to enhance the capability of the Oconee Nuclear Station to withstand the postulated failure of the Jocassee Dam. By letter dated April 30, 2011, the licensee responded to that CAL request. The NRC staff has reviewed the licensee's response, and by letter dated August 18, 2011, requested the licensee to provide clarifying information.

OFFICIAL USE ONLY- SENSITIVE INTERNAL INFORMATION

OFFICIAL USE ONLY* SENSITIVE INTERNAL INFORMATION NFPA 805 Transition Oconee is one of two pilot plants that are in the process of transitioning to NFPA 805 for fire protection. The NRC staff completed its review of the License Amendment Requests (LAR) and issued the final licensee amendment on December 29, 2010. The licensee is currently performing modifications to be in compliance with NFPA 805.

Tornado & High Energy Line Break (HELB) Mitigation The licensee is implementing a number of major modifications designed to minimize the risk exposure resulting from events such as tornado and a high-energy line break. The licensee submitted several LARs to update the Updated Final Safety Analysis Report (UFSAR). The staff has issued numerous Requests for Additional Information and the licensee is in the process of responding to the request.

Digital Computer Based Reactor Protective System (RPS)/Engineered Safeguards Protective System (ESPS)

The licensee is currently implementing a major modification to all three units' Reactor Protection System and Engineered Safeguards Features Actuation System (RPS/ESFAS).

The licensee has installed the new digital system on Unit 1 (performed during the Spring 2011 refueling outage) and is preparing to install the system on Unit 3 in the Spring 2012 outage followed by Unit 2 in the Spring of 2013.

William States Lee Ill Nuclear Station Combined Operating License (COL) Application The licensee submitted a 10 CFR 52 application for a combined operating licensee to the NRC on December 12, 2007, which was docketed on February 25, 2008. This project is on the site of the old Cherokee Nuclear Station project that was cancelled in the 1980's.

Tritium Elevated levels of tritium have been detected in a single ground water monitoring well within the Owner Controlled Area.

NSSS Vendor B&W OFFICIAL USE ONLY- SENSITIVE INTERNAL INFORMATION

OFFICIAL USE ONLY* SENSITIVE INTERNAL INFORMATION TAB4 Facility Unique Features Emergency Supply to 4160 Volt-AC Safety-Related Buses Power to the safety-related buses is provided from the two Keowee Hydro Station generating units. A single Keowee Hydro Unit (KHU) will supply all emergency power. This power is supplied to Oconee by two connections; an overhead transmission line and an underground line. Gas turbines at the Lee Steam Station can also be made available manually via a separate overhead line to provide power if neither KHU is available.

Standby Shutdown Facility (SSF)

The SSF provides an alternate and independent means to achieve and maintain a hot standby condition for all three units following postulated turbine building flood, fire, and sabotage events.

It consists mainly of one diesel generator, an auxiliary service water pump, and supporting equipment (in a seismically qualified building) and three standby makeup pumps (one in each unit's reactor building). Powered by the SSF diesel generator, the standby makeup pumps deliver water at approximately 26 gpm from the associated spent fuel pool to the reactor coolant pump seals. In support of primary decay heat removal, the SSF auxiliary service water pump supplies water from the condenser circulating water (CCW) system to the once-through steam generators. The SSF is able to maintain all three units in Mode 3 (525 degrees) for 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.

The proposed Tornado/HELB mitigation strategies also take credit for the SSF.

Low Pressure Service Water (LPSW)

As originally designed, long-term decay heat removal has relied on the non-safety, non-seismically qualified CCW piping system and its pumps to provide water to the safety-related LPSW pumps located in the turbine building basement. During loss of offsite power events, the CCW pumps lose power; therefore, decay heat removal and cooling water for safety-related pumps rely on the use of a siphon effect (between the lake and the CCW system) to provide water to the safety-related LPSW system.

Emergency Feedwater (EFW)

The safety-related EFW pumps (two per unit) are located in the turbine building basement.

Each unit's EFW system must rely on the limited source of water in its seismically qualified upper surge tank and on the water contained in the condenser hotwell. However, cross-connect valves are provided between all three units' EFW systems. Identified EFW single failure vulnerabilities have been addressed through plant modifications and licensing basis changes/clarifications.

OFFICIAL USE ONLY- SENSITIVE INTERNAL INFORMATION

OFFICIAL USE ONLY* SENSITIVE INTERNAL INFORMATION Containment Isolation Several piping systems penetrating containment were designed without isolation valves (Main Steam), or redundant, reliable (QA-1) isolation devices (Main Feedwater). In 2002, a new automatic feedwater isolation system (AFIS) modification was installed that secures/isolates both main and emergency feedwater to the affected steam generator. Supplemental diesel air compressors are used to compensate for the expected bleed off of valve operating air pressure should a coincident loss of offsite power occur.

The licensee was in the Degraded Cornerstone Column of the NRC's Action Matrix due to a Yellow finding and a White finding related to blockage in the Standby Shutdown Facility (SSF) letdown lines for all three units. A 95002 supplemental inspection was performed in December 2010 and both findings were closed. The licensee moved to the Licensee Response Column of the NRC's Action Matrix in January 2011. There were no safety significant findings in the first or second quarter 2011. On July 5, 2011, a Special Inspection was initiated when the licensee identified that the breakers for pressurizer heaters powered from the SSF could trip prematurely.

As a result of the inspection, three potentially greater than Green findings were identified for failing to maintain design control of SSF components and failing to perform adequate operability evaluations. These finding are currently being evaluted to determine their safety significance.

OFFICIAL USE ONLY- SENSITIVE INTERNAL INFORMATION

OFFICIAL USE ONLY* SENSITIVE INTERNAL INFORMATION TAB6 Current Issues A. EXPECTED DISCUSSION TOPICS External Flood An issue related to the potential impact that external flooding would have on the Oconee Nuclear Station has been raised and is currently being addressed by both the licensee and NRC. The licensee has developed Interim Compensatory Measures to address the dam concerns and is working on permanent actions to ensure the station is not adversely affected by potential external flooding. Regional inspection of the Interim Compensatory Measures was completed in June 2010. On June 22, 2010, the NRC issued a CAL which documented that the licensee would submit a final inundation study by August 2, 2010 (completed), submit a list of modifications by November 30, 2010 (licensee extended until April 2011 ), and complete those modifications by November 30, 2011.

Tornado & HELB Mitigation As a result of a 95002 supplemental inspection of two White Mitigating System tornado-related findings in 2001, it was determined that Oconee has a number of tornado-related vulnerabilities that collectively represented a deficient tornado mitigation strategy. Duke notified the NRC in January 1999 that it was initiating a project to reconstitute the design and licensing basis for HELBs outside the reactor building. The licensee is implementing a number of major modifications designed to minimize the risk exposure resulting from events such as tornado and a high-energy line break, as well as add equipment that had not been part of Oconee's initial design; i.e., main steam isolation valves. The schedule for completion of these activities has been adversely impacted by factors including changes to the design as work is proceeding, quality issues tied to the vendors performing the work, and fabrication issues. The licensee submitted LAR's to update the UFSAR in June 2009.

Digital Computer Based Reactor Protective System (RPS)/Engineered Safeguards Protective System (ESPS)

The licensee is currently implementing a major modification to all three units' Reactor Protection System and Engineered Safeguards Features Actuation System (RPS/ESFAS). The licensee has installed the new digital system on Unit 1 (performed during the Spring 2011 refueling outage) and is preparing to install the system on Unit 3 in the Spring 2012 outage followed by Unit 2 in the Spring of 2013. The Division of Reactor Safety is currently leading the NRC inspection effort supported by the resident inspectors.

William States Lee Ill Nuclear Station Combined Operating License (COL) Application By letter dated December 12, 2007, Duke Energy Carolinas, LLC (Duke) tendered a COL application for two Westinghouse AP1 000 advanced passive pressurized water reactors OFFICIAL USE ONLY- SENSITIVE INTERNAL INFORMATION

OFFICIAL USE ONLY* SENSITIVE INTERNAL INFORMATION designated as Units 1 and 2 of the William States Lee Ill Nuclear Station. The proposed site is located in the eastern portion of Cherokee County in north central South Carolina, approximately 35 miles southwest of Charlotte, North Carolina, and approximately 7.5 miles southeast of Gaffney, South Carolina.

Tritium Elevated levels of tritium have been detected in a ground water monitoring well within the Owner Controlled Area. In February 2010, one well exceeded the 20,000 pCi/1 threshold which initiated the NEI Groundwater Communication plan. The local media outlets carried the story for several days and additional interest was indicated during the annual public meeting for 2009.

The licensee has installed additional monitoring wells and is conducting sampling & analysis to determine if the source is an active leak or a legacy issue. The latest sample values indicate that the tritium levels in the well has decreased below the 20,000 pCi/1 threshold.

B. OTHER TOPICS OF INTEREST Labor/Management Issues None License Renewal Activities The Oconee Site-Specific Independent Spent Fuel Storage Installation (ISFSI) license was renewed on May 29, 2009, for 40 additional years. This included a 20 year renewal plus an exemption which allows for an additional 20 years. The license will now expire on January 31, 2050.

Escalated Enforcement. Non-Green Findings and Non-Green Performance Indicators

  • A licensee-identified potentially greater than Green apparent violation of 10 CFR 50 Appendix B, Criterion Ill, Design Control, was identified when the licensee failed to maintain design control of the Standby Shutdown Facility (SSF). The failure to maintain equipment qualification did not provide reasonable assurance that the SSF auxiliary service water (ASW) subsystem would perform its safety function.
  • An NRC-identified potentially greater than Green apparent violation of 10 CFR 50 Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified when the licensee failed to perform an adequate operability evaluation for the Standby Shutdown Facility (SSF) auxiliary service water subsystem in accordance with NSD 203, Operability/Functionality.

The licensee failed to assure the SSF pressurizer heater breakers would function under expected environmental conditions before declaring the SSF operable but degraded/nonconforming.

  • An NRC-identified potentially greater than Green apparent violation of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified when the licensee OFFICIAL USE ONLY- SENSITIVE INTERNAL INFORMATION

OFFICIAL USE ONLY* SENSITIVE INTERNAL INFORMATION failed to perform a 50.59 evaluation for a compensatory measure for the SSF ASW subsystem in accordance with NSD 203, Operability/Functionality.
