SUBJECT: VOGTLE ELECTRIC GENERATING PLANT - NRC INTEGRATED INSPECTION REPORT 05000424/2011002 AND 05000425/2011002

Dear Mr. Tynan:

On March 31, 2011, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Vogtle Electric Generating Plant, Units 1 and 2. The enclosed integrated inspection report documents the inspection findings, which were discussed on April 22, 2011, with you and other members of your staff.

The inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations and with the conditions of your license. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

This report documents one NRC-identified finding and one self-revealing finding of very low safety significance (Green) which were determined to be violations of regulatory requirements. In addition, one licensee-identified violation which was determined to be of very low safety significance, is listed in the enclosed inspection report. However, because of the very low safety significance and because they were entered into your corrective action program, the NRC is treating these findings as non-cited violations (NCV) consistent with the NRC Enforcement Policy. If you contest any NCV, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN.:

Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at the Vogtle Electric Generating Plant. In addition, if you disagree with the cross-cutting aspect assigned to any finding in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the Regional Administrator, Region II, and the NRC Senior Resident Inspector at the Vogtle facility. The information you provide will be considered in accordance with Inspection Manual Chapter 0305.

SNC 2 In accordance with the Code of Federal Regulations 10 CFR 2.390 of the NRC's Rules of Practice, a copy of this letter, its enclosures, 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 the NRC's document system (ADAMS).

SUMMARY OF FINDINGS

IR 05000424/2011-002, 05000425/2011-002; 1/01/2011 - 3/31/2011; Vogtle Electric Generating Plant, Units 1 and 2; Containment Integrity and Fire Protection

The report covered a three-month period of inspection by two resident inspectors, two senior health physicists, a senior reactor inspector, and a reactor inspector. Two non-cited violations (NCV) with very low safety significance (Green) were identified. The significance of most findings is indicated by their color (great than Green, or Green, White, Yellow, Red); the significance was determined using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process" (SDP); the cross-cutting aspect was determined using IMC 0310,

'Components Within The Cross-Cutting Areas;' and that findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review.

Cornerstone: Barrier Integrity

Green.

The NRC identified a Green NCV of 10 CFR Part 50.55a, "Codes and Standards," for the licensee's failure to conduct a general visual examination of the Units and 2 containment metallic liner around the reactor cavity underneath the reactor vessel. The licensee took corrective actions to conduct the required visual examinations in Unit 1, including ultrasonic testing (UT) thickness measurements to evaluate the condition of the liner, and initiated action items to examine the same area in Unit 2 during the next refueling outage. The licensee initiated Condition Report (CR)2011104688 to address the issue through the Corrective Action Program (CAP) and conducted the required general visual inspection in Unit 1 containment and found no pitting or cracking in the area examined. In addition, the licensee performed UT thickness measurements in affected areas of the metallic liner to evaluate the liner thickness against the design criteria The licensee's failure to conduct a general visual examination of the containment metallic liner in the reactor cavity area underneath the reactor vessel in accordance with the American Society of Mechanical Engineers (ASME) Code,Section XI, Subsection IWE was a performance deficiency. The finding was more than minor because it was associated with the Design Control attribute of the Barrier Integrity Cornerstone and affected the cornerstone objective in that visual inspections of the containment metallic liner were not performed to provide reasonable assurance that the liner remained capable of performing its intended safety function. The finding was of very low safety significance (Green) because the finding did not represent an actual open pathway in the physical integrity of the reactor containment. The finding has a cross-cutting aspect in the operating experience (OE) component of the area of problem identification and resolution because OE was not implemented and institutionalized through station procedures. P.2.b] (Section 1R08)

Cornerstone: Mitigating System

s

Green.

A self-revealing NCV of Vogtle Unit 1 operating license condition 2.G. and Vogtle Unit 2 operating license condition 2.G. was identified for failure to maintain the main firewater header pressurized. Specifically, in response to two firewater header low pressure alarms, operations personnel failed to perform the steps listed in the alarm response procedure. This led to the inadvertent depressurization of the main firewater header. Once the licensee became aware of the system depressurization, the shift supervisor directed an operator to start the available jockey pump, and within a few minutes system pressure was restored. This event was entered into the licensee's corrective action program as CR 2010113782.

The finding is considered more than minor because it is associated with external events attribute of the Mitigating Systems cornerstone. Specifically, the performance deficiency adversely affected the protection against external events (fire) attribute of the Mitigating Systems cornerstone objective to ensure the availability and reliability of systems that respond to initiating events to prevent undesirable consequences. Both the Phase 1 and Phase 2 screening worksheets of IMC 0609, Appendix F, indicated that the violation was potentially greater-than-green. The regional Senior Reactor Analyst completed a Phase 3 evaluation. This evaluation concluded that the violation was of very low safety significance (Green). The inspectors determined that the cause of this finding was related to the Decision-Making component of the Human Performance cross-cutting area due to operators using non-conservative assumptions in their decision making. H.1(a) (Section 4OA5.2)

Violations of very low safety significance, which were identified by the licensee, have been reviewed by the NRC. Corrective actions taken or planned by the licensee have been entered into the licensee's CAP. These violations and corrective action tracking numbers are listed in Section 4OA7 of this report.

1R08 Inservice Inspection (ISI) Activities (Unit 1)

.1 Non-Destructive Examination (NDE) Activities and Welding Activities

a. Inspection Scope

The inspectors reviewed the implementation of the licensee's Risk Informed In-service Inspection (ISI) program for monitoring degradation of the reactor coolant system (RCS) boundary and risk significant piping boundaries. The inspectors activities consisted of an on-site review of NDE and welding activities to evaluate compliance with the applicable edition of the ASME Boiler and Pressure Vessel Code (BPVC),Section XI (Code of record: 2000 Edition through the 2001 Addenda), and that indications and defects (if present) were appropriately evaluated and dispositioned in accordance with the requirements of the ASME Code,Section XI acceptance standards.

The inspectors directly observed the NDE activities listed below and reviewed examination procedures, NDE reports, equipment and consumables certification records, personnel qualification records, and calibration reports (as applicable) for the following examinations:

• UT examination (phased array) of weld 11201-V6-001-W38, RCS Cold Leg Nozzle (ASME Class 1)

• UT examination (conventional automated UT) of weld 11201-V6-001-W37, RCS Hot Leg Nozzle (ASME Class 1)

• Liquid Penetrant Testing (PT) of weld fabricated under Work Order 109009003, half-coupling to 6 in. pipe, Emergency Core Cooling System (ECCS) (ASME Class 2)

The inspectors also reviewed documentation for the following NDE activities:

b. Findings

Introduction:

The NRC identified a Green NCV of 10 CFR Part 50.55a, "Codes and Standards," for the licensee's failure to conduct a visual examination of the Units 1 and 2 containment metallic liners in the area of the reactor cavity underneath the reactor vessel.

Description:

10 CFR 50.55a, "Codes and Standards," requires the licensee to follow the in-service inspection requirements in ASME Section XI. The Code of record for the current containment ISI Program interval at Vogtle Units 1 and 2 is the 2001 Edition with 2003 Addenda of ASME Section XI. In addition, the Code of record for the previous containment ISI Program interval was the 1992 Edition with 1992 Addenda of Section XI. Subsection IWE, Table IWE-2500-1 of both editions of Section XI required a general visual inspection of 100 percent of the containment accessible surface areas during each inspection period. The containment metallic liner in the area of the reactor cavity underneath the reactor vessel is an accessible area within the scope of the general visual examination required by Subsection IWE.

The inspectors determined that the licensee had not inspected the containment liner in the area of reactor cavity underneath the reactor vessel since the beginning of the containment ISI program in 1998. The inspectors also noted that previous operating experience information existed in NRC Information Notices (IN) 2004-09, "Corrosion of Steel Containment and Containment Liner," and IN 2010-12, "Containment Liner Corrosion," relating to material degradation issues of reactor containment building structures. The inspectors determined that this OE was not utilized to ensure adequate procedures were performed to address the necessary inspections. The inspectors identified that licensee procedure 84303-C, "Containment Liner General Visual Examination," Revision 2.0, did not include the reactor cavity area as part of the checklist of areas to be inspected by general visual examination inside the containment.

The licensee initiated Condition Report (CR) 2011104688 to address the issue through the CAP and conducted the required general visual inspection in Unit 1 containment and found no pitting or cracking in the area examined. In addition, the licensee performed UT thickness measurements in affected areas of the metallic liner to evaluate the liner thickness against the design criteria. The visual and UT examinations indicated that the containment metallic liner was acceptable for continuous operation in accordance with the applicable acceptance criteria in ASME Section XI. The licensee developed a plan to recoat the affected area during the upcoming Unit 1 outage and perform a similar visual inspection in the Unit 2 containment during the next refueling outage.

Analysis:

The failure to conduct a general visual examination of 100 percent of the accessible surface areas in the reactor cavity area underneath the reactor vessel in accordance with the ASME BPVC,Section XI, Subsection IWE was a performance deficiency. The finding was more than minor because it was associated with the Design Control attribute of the Barrier Integrity Cornerstone and affected the cornerstone objective of providing reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Specifically, visual inspections of the containment metallic liner provide assurance that the liner remains capable of performing its intended safety function. The inspectors used Inspection Manual Chapter 0609, "Significance Determination Process," Attachment 0609.04, "Phase 1 - Initial Screening and Characterization of Findings," and determined that the finding was of very low safety significance (Green) because the finding did not represent an actual open pathway in the physical integrity of reactor containment.

This finding has a cross-cutting aspect in the operating experience (OE) component of the area of problem identification and resolution because OE was not implemented and institutionalized through station procedures. P.2.b]

Enforcement:

10 CFR Part 50.55a, "Codes and Standards," states in part, that the examination of metallic liners in concrete containments shall satisfy the requirements of ASME Section XI, Subsection IWE of the 1992 Edition with the 1992 Addenda or the 1998 Edition through the latest edition and addenda incorporated by reference in paragraph 10CFR50.55a(b)(2). The 1992 Edition with the 1992 Addenda of ASME Section XI, Subsection IWE; as well as the 2001 edition with 2003 addenda required a general visual examination of 100 percent of the accessible surface areas in concrete containments.

Contrary to the above, from 1998 to 2011, the licensee failed to perform a general visual examination of 100 percent of the containment metallic liner in the reactor cavity area underneath the reactor vessel, an accessible surface area inside the containment, in accordance with the applicable code of record for the first and second containment ISI Program intervals. The licensee took corrective actions to conduct the required visual examinations in Unit 1, including UT thickness measurements to evaluate the condition of the liner, and initiated action items to examine the same area in Unit 2 during the next refueling outage. Because this finding is of very low safety significance and has been entered into the licensee's CAP as CR 2011104688, this violation is being treated as an NCV, consistent with the NRC Enforcement Policy: NCV 05000424, 425/2011002-01, "Failure to Perform General Visual Examination of Containment Metallic Liner in Reactor Vessel Cavity underneath the Reactor Vessel."

.2 PWR Vessel Upper Head Penetration (VUHP) Inspection Activities

a. Inspection Scope

The licensee completed a direct visual examination of the bare-metal outer surface of the Unit 1 reactor vessel upper head in the 2008 refueling outage. The inspectors reviewed visual examination records to evaluate if the activities were conducted in accordance with the requirements of ASME Code Case N-729-1 and 10 CFR 50.55a(g)(6)(ii)(D). Specifically, the inspectors evaluated if the required visual examination scope and coverage was achieved and limitations (if applicable) were recorded in accordance with the licensee procedures. The inspectors also evaluated if the licensee's criteria for visual examination quality and instructions for resolving interference and masking issues were consistent with the regulatory requirements.

The licensee did not identify any indications that required weld repair in the vessel upper head penetrations since the beginning of the last Unit 1 outage. Therefore, no NRC review was completed for this inspection procedure attribute.

b. Findings

No findings were identified.

.3 Boric Acid Corrosion Control (BACC) Inspection Activities

a. Inspection Scope

The inspectors reviewed the licensee's BACC program activities to ensure implementation with commitments made in response to NRC Generic Letter 88-05, "Boric Acid Corrosion of Carbon Steel Reactor Pressure Boundary," and applicable industry guidance documents. Specifically, the inspectors performed an on-site record review of procedures and the results of the licensee's containment walk-down inspections performed during the Unit 1 spring 2011 outage. The inspectors also interviewed the BACC program owner and conducted an independent walk-down of the reactor building to evaluate compliance with licensee's BACC program requirements and verify that degraded or non-conforming conditions, such as boric acid leaks identified during the containment walk-down, were properly identified and corrected in accordance with the licensee's BACC and CAP.

The inspectors reviewed a sample of engineering evaluations completed for evidence of boric acid found on systems containing borated water to verify that the minimum design code required section thickness had been maintained for the affected components. The inspectors selected the following evaluations for review:

• Evaluation No. 1204-2010-007, Evaluation performed on ECCS flow line, February 28, 2011

• Evaluation No. 1208-2011-001, Evaluation performed on single body to bonnet connection bolt, March 14, 2011

b. Findings

No findings were identified.

.4 Steam Generator (SG) Tube Inspection Activities

a. Inspection Scope

The inspectors reviewed the Unit 1 eddy current (EC) examination activities in SGs 1, 2, 3, and 4 to evaluate the inspection activities against the licensee's Technical Specifications (TS), NRC commitments, ASME Section XI, and Nuclear Energy Institute (NEI) 97-06, Steam Generator Program Guidelines. The inspectors reviewed the scope of the EC examinations to verify it included the applicable potential areas of tube degradation. The inspectors also verified that appropriate inspection scope expansion criteria were planned based on inspection results. Additionally, the inspectors reviewed EC examination status reports to ensure that all tubes with relevant indications were appropriately screened for in-situ pressure testing. Based on the EC examination results, no new degradation mechanisms were identified, no EC scope expansion was required, and none of the SG tubes examined met the criteria for in-situ pressure testing.

The inspectors reviewed the last Condition Monitoring and Operational Assessment report to assess the licensee's prediction capability for maximum tube degradation. The inspectors' review also included the licensee's repair criteria and repair process to ensure they were consistent with plant TS and industry guidelines. This included direct observation of tube plugging activities in SGs 1 and 4. The inspectors also reviewed the primary to secondary leakage (e.g., SG tube leakage) history for the last operating cycle. The inspectors noted that primary to secondary leakage was below the detection threshold during the previous operating cycle.

Additionally, the inspectors reviewed documentation to ensure that data analysts, EC probes, and equipment configurations were qualified to detect the existing and potential SG tube degradation mechanisms. The inspectors' review included a sample of site-specific Examination Technique Specification Sheets (ETSSs) to ensure that their qualification was consistent with Appendix H or I of the Electric Power Research Institute Pressurized Water Reactor Steam Generator Examination Guidelines, Revision 7. The inspectors also directly observed a sample of EC data acquisition in SGs 1 and 4 (Cold Leg and Hot Leg sides). Furthermore, the inspectors reviewed a sample of EC data with a qualified data analyst for the following tubes: SG 1 (R26C110, R57C45, R39C100, and R41C100); and SG 4 (R8C57 and R30C18). Finally, the inspectors reviewed the licensee's corrective actions for indications (either from EC or secondary side visual inspections) of potential loose parts on the SG secondary side, including direct observation of Foreign Object Search and Retrieval (FOSAR) activities.

b. Findings

No findings were identified.

.5 Identification and Resolution of Problems

a. Inspection Scope

The inspectors performed a review of ISI-related problems, including welding, BACC, and SG ISI that were identified by the licensee and entered into the CAP as CRs. The inspectors reviewed the CRs to confirm that the licensee had appropriately described the scope of the problem and had initiated corrective actions. The review also included the licensee's consideration and assessment of operating experience events applicable to the plant. The inspectors performed this review to ensure compliance with 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Action," requirements. The corrective action documents reviewed by the inspectors are listed in the report Attachment.

b. Findings

No findings were identified

1R11 Licensed Operator Requalification

a. Inspection Scope

Resident Quarterly Observation. The inspectors observed operator performance on February 14, during licensed operator simulator training described in simulator exercise guide V-RQ-SE-11101-1.0. The scenario observed consisted of a steam generator tube rupture followed by a failed code safety valve on the ruptured steam generator. Documents reviewed are listed in the Attachment. The inspectors specifically assessed the following areas:

• Correct use of the abnormal and emergency operating procedures

• Ability to identify and implement appropriate actions in accordance with the requirements of the TS

• Clarity and formality of communications in accordance with procedure 10000-C, Conduct of Operations

• Proper control board manipulations including critical operator actions

• Quality of supervisory command and control

• Effectiveness of the post-evaluation critique

b. Findings

No findings were identified.

1R12 Maintenance Effectiveness

a. Inspection Scope

4OA3 Event Follow-up

.1 (Closed) Licensee Event Report 05000424/2010-001:

Breaker Failure Results in 1B Train Containment Cooling System Being Declared Inoperable On October 24, 2010, the licensee attempted to manually start Containment Cooling Unit #8 in low speed during the performance of a Containment Cooling System Operability and Response Time Test and the cooling unit did not start. Work Order (WO) 1102198301 investigation identified that the circuit breaker had two breaker cover mounting holes that were cracked. This allowed the top right hand side screw to come in contact with the breaker's closing mechanism, thus preventing the breaker from closing. The inspectors reviewed the LER, the associated condition report and apparent cause determination, and subsequent action items. The enforcement aspects associated with this event were documented in NRC integrated inspection report 05000424,425/2010005 Section 4OA2. No other findings were identified. This LER is closed.

Depressurization of Main Firewater Header

a. Inspection Scope

The inspectors performed a detailed review of CR 2010113782 which addressed the inadvertent depressurization of the main firewater header. The goal of the review was to verify that the full extent of the issue was identified, an appropriate evaluation was performed, and appropriate corrective actions were specified and prioritized.

b. Findings and Observations

Introduction:

A self-revealing, Green NCV of Vogtle Unit 1 operating license condition 2.G. and Vogtle Unit 2 operating license condition 2.G. was identified for failure to maintain the main firewater header pressurized. Specifically, in response to two firewater header low pressure alarms, operations personnel failed to perform the steps listed the alarm response procedure. This led to the inadvertent depressurization of the main firewater header. For a period of 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> and 21 minutes, the facility lost all automatic sprinkler system and manual hose station capability. If there had been an automatic actuation of the sprinkler system or a demand from any of the hose stations in the facility during that time period, there would have been no water available for fire suppression.

Description:

At 0339 on November 1, 2010, both of the diesel firewater pumps and the north jockey pump were placed out of service and danger tagged to permit replacement of the relief valves on the diesel-driven pumps. As part of the tagout, the remote indicator in the control room for fire header pressure was also removed from service. The licensee entered the appropriate 7-day fire protection LCO action statement at that time. When the operators secured the north jockey pump for the tagout, they incorrectly assumed that the south jockey pump was in operation. In reality, the south jockey pump was also not operating and its hand switch was in the off position. This was in accordance with the governing procedure as the facility only requires one of the two jockey pumps to maintain 120 psig in the firewater header. As pressure in the firewater header began to decrease, the motor-driven firewater pump failed to start automatically at 100 psig. It was later discovered that the auto-start pressure switch had failed on demand. Also as pressure decreased, two independent firewater header low pressure alarms were received in the control room. The operators incorrectly assumed that the alarms were due to the tagout of the diesel-driven pumps and therefore did not perform the actions listed in the alarm response procedure.

At approximately 1700 on November 1, a third party inspector, who was inspecting the fire protection system as part of an assistance team, noticed that several of the local firewater header pressure gauges were reading very low. He brought this fact to the attention of a system operator who immediately contacted the control room. The shift supervisor immediately dispatched an operator to the south firewater station, where he reported that the firewater header was depressurized, and neither the south jockey pump nor the motor-driven firewater pump were running. The shift supervisor directed that the operator start the jockey pump, and within a few minutes system pressure was restored. Several minutes after that, the shift supervisor directed that the motor-driven firewater pump be started manually to verify functionality. The motor-driven firewater pump was started and ran for several minutes while maintenance personnel tried to determine why the pump had failed to automatically start at 100 psig.

Maintenance personnel discovered that the motor-driven firewater pump did not start due to a failed pressure switch. With all three firewater pumps inoperable, the licensee immediately entered the appropriate 24-hour fire protection shutdown LCO action statement. Within a few hours, one of the diesel-driven firewater pumps was restored and declared operable, and the shutdown LCO action statement was exited.

Analysis:

The failure of the licensee to properly respond to a firewater header low pressure alarms led directly to the depressurization of the main firewater header, and is considered a performance deficiency. The performance deficiency is considered more than minor because it is associated with the external events attribute and it adversely affected the objective of the Mitigating Systems cornerstone. Specifically, the performance deficiency adversely affected the protection against external events (fire) attribute of the Mitigating Systems cornerstone objective to ensure the availability and reliability of systems that respond to initiating events to prevent undesirable consequences.

In accordance with IMC 0609.04, Phase 1 - Initial Screening and Characterization of Findings, this violation was assessed using the Phase 1 screening worksheets of IMC 0609, Appendix F. The results of the Phase 1 worksheets indicated that the CDF was greater than 1E-6, which indicated that a Phase 2 worksheet was required. The Phase 2 screening worksheet indicated that the violation was potentially greater-than-green ( CDF was greater than 1E-6), and the violation was forwarded to a Region II Senior Reactor Analyst (SRA) for a Phase 3 evaluation.

The regional SRA performed an evaluation under the Phase 3 protocol of the Significance Determination Process. This evaluation concluded that the violation was of very low safety significance (Green). The major assumptions of the evaluation included:

• an exposure time of less than fourteen hours

• the cables within the facility were thermo-set

• one train of safe shutdown equipment was free of fire damage for any compartment within the Auxiliary Building (excluding the Main Control Room and Cable Spread Rooms)

• there were no critical operator manual actions for fires in the Auxiliary Building compartments (excluding the Main Control Room and Cable Spread Rooms)

• all water suppression actions fail, due to the performance deficiency The dominant accident sequence was an unsuppressed electrical cabinet fire in the Auxiliary Building which induced a loss of offsite power. One emergency diesel generator failed to run and the other one was out of service for maintenance. Recovery actions for the emergency diesel generators and offsite power were unsuccessful and core damage ensued.

The inspectors determined that the cause of this finding was related to the Decision-Making component of the Human Performance cross-cutting area due to operators using non-conservative assumptions in their decision making. H.1(a)

Enforcement

Vogtle Unit 1 operating license condition 2.G. and Vogtle Unit 2 operating license condition 2.G. requires the licensee to implement and maintain in effect all provisions of the approved fire protection program as described in the Final Safety Analysis Report (FSAR). Section 9.5.1.2.2 - Fire Protection (Active Systems) of the Vogtle FSAR requires the fire protection water system be kept continuously full and pressurized. Contrary to the above operating license conditions, on November 1, 2010, the licensee inadvertently allowed the fire water header to be depressurized for a period of 13 hours1.50463e-4 days <br />0.00361 hours <br />2.149471e-5 weeks <br />4.9465e-6 months <br /> and 21 minutes. If there had been an automatic actuation of the sprinkler system or a demand from any of the manual hose stations in the facility during that time period, there would have been no water available for fire suppression. Once the licensee became aware of the system depressurization, the shift supervisor directed an operator to start the available jockey pump, and within a few minutes system pressure was restored. The licensee then entered the appropriate 24-hour fire protection shutdown LCO action statement and remained there until operability of one diesel-driven firewater pump was restored a few hours later.

Because this violation was of very low safety significance and it was entered into the licensee's corrective action program (ref. CR 2010113782), this violation is being treated as an NCV, consistent with the NRC Enforcement Policy. This finding is identified as NCV 05000424, 425/2011002-02, Depressurization of Main Firewater Header.

4OA6 Meetings, Including Exit

.1 Exit Meeting

On April 22, 2011, the resident inspectors presented the inspection results to you and other members of your staff, who acknowledged the findings. The inspectors confirmed that proprietary information was not provided or examined during the inspection.

4OA7 Licensee Identified Violations

The following violations of very low safety significance (Green) were identified by the licensee and are a violation of NRC requirements which meet the criteria of the NRC Enforcement Policy, for being dispositioned as a NCV.

• Technical Specifications LCO 3.0.2 requires that "Upon discovery of a failure to meet an LCO, the Required Actions of the associated Conditions shall be met, except as provided in LCO 3.0.5 and LCO 3.0.6." LCO 3.5.4 requires the RWST to be operable. On at least six occasions in the past 12 months, the licensee failed to enter LCO 3.5.4 condition B while performing testing that made the RWST sludge mixing pump isolation valves inoperable. The finding was determined to be of very low safety significance (Green) because the events did not represent in an actual loss of safety function of a single train for greater than its Technical Specification allowed outage time. The licensee has documented this event in their corrective action program (CR 2011100919), conducted a basic cause determination, and developed applicable corrective actions (AI 2011201473).
