==Dear Mr. Baxter:== | ==Dear Mr. Baxter:== | ||
On September 30, 2008, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Oconee Nuclear Station. The enclosed report documents the inspection results which were discussed on October 9, 2008, with you and members of your staff. The inspection examined activities conducted under your licenses as they relate to safety and compliance with the Commission's rules and regulations and with the conditions of your licenses. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel. Based on the results of the inspection, no findings of significance were identified. However, a licensee identified violation, which was determined to be of very low safety significance, is listed in this report. Because of the very low safety significance and because it is entered into your corrective action program, the NRC is treating the finding as a non-cited violation (NCV), consistent with Section VI.A.1 of the NRC Enforcement Policy. If you contest any NCV in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the United States Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555-0001, with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, D.C. 20555-0001; and the NRC Resident Inspector at the Oconee facility. | On September 30, 2008, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Oconee Nuclear Station.

(a) Unit 1: Hot Leg Decay Heat Removal Nozzle DMBW after mitigation by FSWOL (b) Unit 2: Hot Leg Surge Line Nozzle DMBW after mitigation by FSWOL (c) Unit 3: Pressurizer Surge Line DMBW after mitigation by FSWOL | |||
22 Enclosure (1) For each examination inspected, was the activity performed in accordance with the examination guidelines in MRP-139, Section 5.1, for unmitigated welds or mechanical stress improved welds and consistent with NRC staff relief request authorization for overlaid welds? | |||
Yes, the volumetric examination of the welds listed above were performed in accordance with a qualified procedure for UT examination, consistent with MRP-139 requirements and the proposed alternatives approved by the NRC in two safety evaluation reports (SERs) dated August 6, 2007, and January 17, 2008, (ADAMS Accession Numbers ML071280781 and ML073460027, respectively). | |||
The procedure was a vendor's proprietary procedure for UT phased array and it was qualified in accordance with ASME Section XI, Appendix VIII, as implemented through the EPRI PDI Program. Prior to the examination, the licensee verified the FSWOL surface flatness and roughness to ensure it permitted volumetric examination. The licensee conducted the examination at the proper time after the FSWOL was completed. The licensee was able to obtain adequate coverage in the UT examination. | |||
(2) For each examination inspected, was the activity performed by qualified personnel? | |||
Yes, the personnel involved in the UT examinations listed above were qualified in accordance with MRP-139 requirements and the licensee's proposed alternative.

(a) Unit 1: Hot Leg Decay Heat Removal Nozzle FSWOL (b) Unit 2: Hot Leg Surge Line Nozzle FSWOL (c) Unit 3: Pressurizer Surge Line FSWOL | |||
23 Enclosure (1) For each weld overlay inspected, was the activity performed in accordance with ASME Code welding requirements and consistent with NRC staff relief requests authorizations? Has the licensee submitted a relief request and obtained NRR staff authorization to install weld overlays? | |||
Yes, the licensee installed the FSWOLs listed above in accordance with the applicable sections of the ASME Boiler and Pressure Vessel Code (ASME Code). The licensee submitted relief requests (RRs) 06-ON-004, 07-ON-001, and 07-ON-004 to request approval for proposed alternatives to certain ASME Code requirements for the purpose of performing FSWOLs. On August 6, 2007 and January 17, 2008, the NRC issued two SERs to approve the proposed alternatives (ADAMS Accession Numbers ML071280781 and ML073460027, respectively). | |||
The inspectors reviewed welding procedure specifications, procedure qualification records, weld filler metal certifications, and welding process control sheets for the FSWOLs listed above to verify compliance with ASME Section IX requirements and adherence to the SERs. The inspectors also reviewed a number of non-conformance reports regarding weld overlay quality issues to ensure that they were properly evaluated and corrected without deviations from the approved alternatives. | |||
(2) For each weld overlay inspected, was the activity performed by qualified personnel? | |||
Yes, welding personnel involved in the FSWOLs listed above were qualified in accordance with the requirements identified in ASME Code Section IX, "Qualification Standard for Welding and Brazing Procedures, Welders, Brazers, and Welding and Brazing Operators." The inspectors reviewed the welder performance qualification test records and welding process control sheets to verify that welders were qualified for the specific welding method they implemented. | |||
(3) For each weld overlay inspected, was the activity performed such that deficiencies were identified, dispositioned, and resolved? | |||
Yes, the inspectors reviewed non-conformance documentation to verify that deficiencies were evaluated and corrected. Based on inspection activities, the inspectors determined that the installation of the FSWOL was conducted in a manner such that deficiencies were identified, dispositioned, and resolved. | |||
Mechanical Stress Improvement (Not Applicable) | |||
The licensee has not implemented Mechanical Stress Improvement as a mitigation method for DMBWs. | |||
24 Enclosure In-service Inspection Program (1) Has licensee prepared an MRP-139 in-service inspection program? | |||
No, the licensee did not have a stand alone MRP-139 in-service inspection program document. The licensee's MRP-139 inspection program consisted of the documents listed below, which were previously prepared documents, and the inclusion of MRP-139 requirements as augmented inspections in the ASME Section XI In-service Inspection Program (ISI Program). The inspectors reviewed the following documents and held discussions with licensee representatives: | |||
* Engineering Support Document (ESD) - "Alloy 600 Aging Management: Oconee, McGuire, and Catawba Nuclear Stations," Revision 3 | |||
* Fourth Ten-Year Interval In-service Inspection Plan, Oconee Nuclear Station Units 1, 2,3, and Keowee Hydro Station Units 1 & 2 General Requirements, Revision 1 | |||
* Fourth Ten-Year Interval In-service Inspection Plan, Oconee Nuclear Station Unit 1, Revision 1 | |||
* Fourth Ten-Year Interval In-service Inspection Plan, Oconee Nuclear Station Unit 2, Revision 1 | |||
* Fourth Ten-Year Interval In-service Inspection Plan, Oconee Nuclear Station Unit 3 and Keowee Hydro Station Units 1 & 2, Revision 1 (2) In the MRP-139 in-service inspection program, are the welds appropriately categorized in accordance with MRP-139? | |||
The inspectors reviewed all identified DMBWs within the scope of MRP-139 for appropriate categorization in accordance with Section 6 of that document. The licensee did not have a stand alone program describing all the welds within the scope of MRP-139 and what category each weld fell into. The licensee used the ISI program to identify all DMBWs within scope of MRP-139, schedule the corresponding in-service inspections, and specify the inspection frequencies consistent with the categories in MRP-139. | |||
The licensee excluded three locations with Alloy 82/182 from the scope of MRP-139 program: Core Flood Tank nozzles, Core Flood Tank pressure relief nozzles, and cold leg HPI/Make-up Nozzles. The licensee considered that the Core Flood Tank nozzles are not part of the primary system and their operating temperature is significantly lower than the cold leg temperature, and therefore they are outside the scope of MRP-139. On the other hand, the integrity of the cold leg HPI/Make-up nozzles is monitored under the Thermal Fatigue Management Program. Since 1997, Oconee Units 1, 2 and 3 have had thermal fatigue issues 25 Enclosure at the HPI/Make-up nozzles, which have resulted in weld failures and thermal sleeve cracking. In response to this thermal fatigue issue, the licensee has implemented design changes, replaced part of the Alloy 82/182 with Alloy 52/152, and increased visual and volumetric inspections frequencies. The licensee considered that thermal fatigue was a dominant failure mechanism compared with primary water stress corrosion cracking and therefore they have followed a more conservative inspection and evaluation program than MRP-139. Currently, the licensee conducts volumetric inspection of the HPI/Make-up nozzles DMBWs in Units 1, 2, and 3 every other outage using a PDI qualified procedure. This inspection frequency exceeds the requirements of MRP-139. | |||
(3) Are inspection frequencies consistent with the requirements of MRP-139? | |||
Yes, planned inspection frequencies for welds in the MRP-139 program are consistent with the requirements of MRP-139. | |||
(4) What is the licensees' basis for categorizing welds as H or I and plans for addressing potential PWSCC? | |||
No welds were categorized as Categories H or I. | |||
(5) What deviations has the licensee incorporated and what approval process was used? No deviations to MRP-139 have been incorporated by the licensee. | |||
( | 4OA6 Management Meetings (Including Exit Meeting) | ||
Exit Meeting Summary The inspectors presented the inspection results to Mr. David Baxter, Site Vice President, and other members of licensee management at the conclusion of the inspection on October 9, 2008. The licensee acknowledged the findings presented. The inspectors asked the licensee whether any of the material examined during the inspection should be considered proprietary. No proprietary information was identified. | |||
4OA7 Licensee Identified Violations The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for disposition of NCVs. | |||
* TS 5.4.1 requires that procedures shall be established, implemented and maintained covering the applicable procedures recommended in Regulatory Guide 1.33. Regulatory Guide 1.33, Appendix A, Section 9, requires procedures for performing maintenance. Contrary to the above, the licensee failed to adequately establish and implement their procedure for SSF pressurizer heater switch replacement such that the switch for the Unit 1 bank 2 group C heaters 26 Enclosure was wired to prevent normal operation. This was identified in the licensee's corrective action program as PIP O-08-3958. This finding is of very low safety significance because it does not represent a design or qualification deficiency resulting in the loss of operability or functionality. | |||

SUBJECT: OCONEE NUCLEAR STATION - INTEGRATED INSPECTION REPORT 05000269/2008004, 05000270/2008004, AND 05000287/2008004
Dear Mr. Baxter:
On September 30, 2008, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Oconee Nuclear Station. The enclosed report documents the inspection results which were discussed on October 9, 2008, with you and members of your staff.
The inspection examined activities conducted under your licenses as they relate to safety and compliance with the Commission's rules and regulations and with the conditions of your licenses. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
Based on the results of the inspection, no findings of significance were identified. However, a licensee identified violation, which was determined to be of very low safety significance, is listed in this report. Because of the very low safety significance and because it is entered into your corrective action program, the NRC is treating the finding as a non-cited violation (NCV), consistent with Section VI.A.1 of the NRC Enforcement Policy. If you contest any NCV in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the United States Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555-0001, with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, D.C. 20555-0001; and the NRC Resident Inspector at the Oconee facility.
DEC 2 In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

REACTOR SAFETY Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity 1R01 Adverse Weather Protection
.1 Severe Thunderstorm Warning a. Inspection Scope The inspectors assessed if the licensee responded appropriately to a severe thunderstorm warning issued for the area surrounding the Oconee Nuclear Station on August 5, 2008. The inspectors discerned whether operations personnel entered Abnormal Procedure (AP) AP/0/A/1700/006, Natural Disaster, initiated Enclosure 5.4, Severe Weather, and reviewed Enclosure 5.1, Tornado Information.
b. Findings No findings of significance were identified.
4 Enclosure .2 Tornado Warning a. Inspection Scope The inspectors assessed if the licensee responded appropriately to a tornado warning issued by the National Weather Service for the area surrounding the Oconee Nuclear Station on August 26, 2008. The inspectors verified that operations personnel entered AP/0/A/1700/006, Natural Disaster, and that efforts to restore Keowee Hydro Unit (KHU) 2 and the A train of Emergency Feedwater to service from planned maintenance and testing were underway in accordance with Enclosure 5.2, Tornado Warning, of the AP. The inspectors also determined whether all control room personnel reviewed Enclosure 5.1, Tornado Information, and per Enclosure 5.2, Tornado Warning, dispatched a licensed operator to the standby shutdown facility (SSF) to establish communications with the control room and dispatched an operator to the station auxiliary service water pump to align the pump per Enclosure 5.10 of the Unit 1 emergency operating procedure.
b. Findings No findings of significance were identified.
1R04 Equipment Alignment Partial Walkdown a. Inspection Scope The inspectors conducted partial equipment alignment walkdowns to evaluate the operability of selected redundant trains or backup systems while the other train or system was inoperable or out-of-service (OOS). The walkdowns included, as appropriate, reviews of plant procedures and other documents to determine correct system lineups, and verification of critical components to identify any discrepancies which could affect operability of the redundant train or backup system. Documents reviewed are listed in the Attachment to this report. The following systems were included in this review:
- Unit 1 and 2 B and C Low Pressure Service Water (LPSW) pumps with A LPSW pump OOS for preventive maintenance (PMs)
- 1B Low Pressure Injection (LPI) and Reactor Building Spray (RBS) trains with 1A LPI and RBS trains OOS for 1LP-21 PMs
b. Findings No findings of significance were identified.
5 Enclosure 1R05 Fire Protection Fire Area Walkdowns
a. Inspection Scope The inspectors conducted tours in selected areas of the plant to assess whether combustibles and ignition sources were properly controlled, and that fire detection and suppression capabilities were intact. The inspectors selected the areas based on a review of the licensee's safe shutdown analysis and the probabilistic risk assessment based sensitivity studies for fire-related core damage sequences. Documents reviewed are listed in the Attachment to this report. The following areas were inspected during this inspection period:
- Unit 1 and 2 Control Room (1)
- Unit 3 Control Room (1)
- Turbine Building Basement (1)

The licensee submitted relief requests (RRs) 06-ON-004, 07-ON-001, and 07-ON-004 to request approval for proposed alternatives to certain ASME Code requirements for the purpose of performing FSWOLs. On August 6, 2007 and January 17, 2008, the NRC issued two SERs to approve the proposed alternatives (ADAMS Accession Numbers ML071280781 and ML073460027, respectively).
The inspectors reviewed welding procedure specifications, procedure qualification records, weld filler metal certifications, and welding process control sheets for the FSWOLs listed above to verify compliance with ASME Section IX requirements and adherence to the SERs. The inspectors also reviewed a number of non-conformance reports regarding weld overlay quality issues to ensure that they were properly evaluated and corrected without deviations from the approved alternatives.
(2) For each weld overlay inspected, was the activity performed by qualified personnel?
Yes, welding personnel involved in the FSWOLs listed above were qualified in accordance with the requirements identified in ASME Code Section IX, "Qualification Standard for Welding and Brazing Procedures, Welders, Brazers, and Welding and Brazing Operators." The inspectors reviewed the welder performance qualification test records and welding process control sheets to verify that welders were qualified for the specific welding method they implemented.
(3) For each weld overlay inspected, was the activity performed such that deficiencies were identified, dispositioned, and resolved?
Yes, the inspectors reviewed non-conformance documentation to verify that deficiencies were evaluated and corrected. Based on inspection activities, the inspectors determined that the installation of the FSWOL was conducted in a manner such that deficiencies were identified, dispositioned, and resolved.
Mechanical Stress Improvement (Not Applicable)
The licensee has not implemented Mechanical Stress Improvement as a mitigation method for DMBWs.
24 Enclosure In-service Inspection Program (1) Has licensee prepared an MRP-139 in-service inspection program?
No, the licensee did not have a stand alone MRP-139 in-service inspection program document. The licensee's MRP-139 inspection program consisted of the documents listed below, which were previously prepared documents, and the inclusion of MRP-139 requirements as augmented inspections in the ASME Section XI In-service Inspection Program (ISI Program). The inspectors reviewed the following documents and held discussions with licensee representatives:
- Engineering Support Document (ESD) - "Alloy 600 Aging Management: Oconee, McGuire, and Catawba Nuclear Stations," Revision 3
- Fourth Ten-Year Interval In-service Inspection Plan, Oconee Nuclear Station Units 1, 2,3, and Keowee Hydro Station Units 1 & 2 General Requirements, Revision 1
- Fourth Ten-Year Interval In-service Inspection Plan, Oconee Nuclear Station Unit 1, Revision 1
- Fourth Ten-Year Interval In-service Inspection Plan, Oconee Nuclear Station Unit 2, Revision 1
- Fourth Ten-Year Interval In-service Inspection Plan, Oconee Nuclear Station Unit 3 and Keowee Hydro Station Units 1 & 2, Revision 1 (2) In the MRP-139 in-service inspection program, are the welds appropriately categorized in accordance with MRP-139?
The inspectors reviewed all identified DMBWs within the scope of MRP-139 for appropriate categorization in accordance with Section 6 of that document. The licensee did not have a stand alone program describing all the welds within the scope of MRP-139 and what category each weld fell into. The licensee used the ISI program to identify all DMBWs within scope of MRP-139, schedule the corresponding in-service inspections, and specify the inspection frequencies consistent with the categories in MRP-139.
The licensee excluded three locations with Alloy 82/182 from the scope of MRP-139 program: Core Flood Tank nozzles, Core Flood Tank pressure relief nozzles, and cold leg HPI/Make-up Nozzles. The licensee considered that the Core Flood Tank nozzles are not part of the primary system and their operating temperature is significantly lower than the cold leg temperature, and therefore they are outside the scope of MRP-139. On the other hand, the integrity of the cold leg HPI/Make-up nozzles is monitored under the Thermal Fatigue Management Program. Since 1997, Oconee Units 1, 2 and 3 have had thermal fatigue issues 25 Enclosure at the HPI/Make-up nozzles, which have resulted in weld failures and thermal sleeve cracking. In response to this thermal fatigue issue, the licensee has implemented design changes, replaced part of the Alloy 82/182 with Alloy 52/152, and increased visual and volumetric inspections frequencies. The licensee considered that thermal fatigue was a dominant failure mechanism compared with primary water stress corrosion cracking and therefore they have followed a more conservative inspection and evaluation program than MRP-139. Currently, the licensee conducts volumetric inspection of the HPI/Make-up nozzles DMBWs in Units 1, 2, and 3 every other outage using a PDI qualified procedure. This inspection frequency exceeds the requirements of MRP-139.
(3) Are inspection frequencies consistent with the requirements of MRP-139?
Yes, planned inspection frequencies for welds in the MRP-139 program are consistent with the requirements of MRP-139.
(4) What is the licensees' basis for categorizing welds as H or I and plans for addressing potential PWSCC?
No welds were categorized as Categories H or I.
(5) What deviations has the licensee incorporated and what approval process was used? No deviations to MRP-139 have been incorporated by the licensee.
4OA6 Management Meetings (Including Exit Meeting)
Exit Meeting Summary The inspectors presented the inspection results to Mr. David Baxter, Site Vice President, and other members of licensee management at the conclusion of the inspection on October 9, 2008. The licensee acknowledged the findings presented. The inspectors asked the licensee whether any of the material examined during the inspection should be considered proprietary. No proprietary information was identified.
4OA7 Licensee Identified Violations The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which meet the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for disposition of NCVs.
- TS 5.4.1 requires that procedures shall be established, implemented and maintained covering the applicable procedures recommended in Regulatory Guide 1.33. Regulatory Guide 1.33, Appendix A, Section 9, requires procedures for performing maintenance. Contrary to the above, the licensee failed to adequately establish and implement their procedure for SSF pressurizer heater switch replacement such that the switch for the Unit 1 bank 2 group C heaters 26 Enclosure was wired to prevent normal operation. This was identified in the licensee's corrective action program as PIP O-08-3958. This finding is of very low safety significance because it does not represent a design or qualification deficiency resulting in the loss of operability or functionality.
