SUBJECT:
MCGUIRE NUCLEAR STATION - NRC INTEGRATED INSPECTION REPORT 05000369/2005004 AND 05000370/2005004 AND INDEPENDENT SPENT FUEL STORAGE INSTALLATION INSPECTION REPORT 0720038/2005002
Dear Mr. Peterson:
On September 30, 2005, the US Nuclear Regulatory Commission (NRC) completed an inspection at your McGuire Nuclear Station. The enclosed report documents the inspection findings which were discussed on October 6, 2005 with you and members of your staff.
The inspection examined activities conducted under your licenses as they relate to safety and compliance with the Commissions 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 this inspection, there was one NRC-identified finding of very low safety significance (Green) identified in the report which was determined to be a violation of NRC requirements. However, because of its very low safety significance and because it was entered into your corrective action program, the NRC is treating it as non-cited violation (NCV)
consistent with Section VI.A of the NRC Enforcement Policy. In addition, the NRC identified a Severity Level IV violation of 10 CFR50.71(e) for a failure to update the Updated Final Safety Analysis Report. It was determined that this violation should also be non-cited in accordance with Section VI.A of the NRCs Enforcement Policy. Furthermore, one licensee-identified violation, which was determined to be of very low safety significance (Green), is listed in Section 4OA7 of this report. If you contest and NCV in this report, you should provide a response with the basis for your denial, within 30 days of the date of this inspection report, 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 McGuire facility.
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
DEC 2 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).

SUMMARY OF FINDINGS IR05000369/200500 , IR05000370/200500 ; 07/01/2005 - 09/30/2005; McGuire Nuclear Station, Units 1 and 2; Identification and Resolution of Problems.
The report covered a three month period of inspection by resident inspectors and announced inspections by regional inspectors. One Green non-cited violation (NCV) and one severity level 4 (SL4) NCV were identified. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using IMC 0609, Significance Determination Process (SDP).
Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 3, dated July 2000.
A. NRC-Identified and Self-Revealing Findings Cornerstone: Mitigating Systems
- Green. A non-cited violation was identified by the inspectors for untimely corrective action to update the Updated Final Safety Evaluation Report (UFSAR)
related to the Standby Shutdown Facility (SSF). This issue was originally identified on February 17, 2004, and as of August 3, 2005, no corrective action had been taken to include the SSF in the UFSAR either by revision or approved change package for the next revision, and the corrective action item was closed.
The issue was determined to be a severity level IV violation in NRC Inspection Report 05000369,370/2004003. The untimely corrective action was considered for being a cited violation in accordance with section VI.A.1 of the NRC Enforcement Policy. However, because the licensee completed and approved a UFSAR change package and adequately determined the cause of the untimely corrective action prior to the end of the inspection period, no additional information would be gained from the licensee providing a written response.
This finding involved the crosscutting aspect of Problem Identification and Resolution. (Section 4OA2b.(1))
Cornerstone: Barrier Integrity
- SL4. A non-cited violation was identified by the inspectors for failure to update the UFSAR as required by 10 CFR 50.71(e) related to inclusion of the license amendment request safety analysis information pertaining to the use of alternative instrumentation and procedures in place of seismic qualification for the Containment Atmosphere Particulate Monitors (CAPRMs).
The issue was greater than minor because the failure to include in the UFSAR the alternative methodology for RCS leakage detection after a seismic event with unqualified CAPRMs, as described in the licensees safety analysis, was material to the acceptability of the license amendment requests. The inspectors found no subsequent changes made to the facility that were based on the erroneous information in the UFSAR section. Consequently, this issue was considered to
meet the criteria of a severity level IV violation. This finding involved the crosscutting aspect of Problem Identification and Resolution. (Section 4OA2b.(2))
B. Licensee-Identified Violations A violation of very low safety significance, which was identified by the licensee has been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. This violation and the corrective action tracking number is listed in Section 4OA7 of this report.
Report Details Summary of Plant Status:
Unit 1 began the inspection period at approximately 100 % rated thermal power (RTP). On July 7, Unit 1 experienced a turbine runback to approximately 50% RTP due to turbine generator output bus line breaker 1A tripping. The unit returned to 100% RTP on July 9. The unit reduced power and entered a refueling outage on September 17. The unit remained in the refueling outage through the rest of the period.
Unit 2 began the inspection period at approximately 100 % RTP and remained there through the end of the inspection period.
1. REACTOR SAFETY Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity 1R01 Adverse Weather Protection a. Inspection Scope Tornado watches were declared on July 7 and August 30, and the licensee took actions in accordance with procedure RP/0/A/5700/006, Natural Disasters. Prior to the onset of that weather, the inspectors reviewed the licensees actions to ensure that the adverse weather conditions would neither initiate a plant event nor prevent any system, structure, or component from performing its design function.
After the licensee completed preparations for seasonal high temperature, the inspectors discussed the licensees Hot Weather Program and the licensees hot weather computer spreadsheet for 2004 and 2005 with the licensees program owner. The inspectors reviewed the completed test results for PT/0/B/4700/039, Warm Weather Equipment Checkout, dated April 17, 2005. In addition to evaluating any safety-related equipment affected by hot weather, the inspectors toured the plant to determine if other equipment not monitored by the program could be affected.
The inspectors reviewed the following PIP associated with this area, to verify that the licensee identified and implemented appropriate corrective actions:
- M-05-2408, CF Pump Oil Cooler Outlet Temperature High b. Findings No findings of significance were identified.
1R04 Equipment Alignment a. Inspection Scope Partial System Walkdowns During this inspection period, the inspectors performed the following partial system walkdowns, while the indicated structures, systems, and components (SSCs) were out of service for maintenance and testing:

- Unit 2 train A Component Cooling Water with train B out of service on July 12
- Unit 2 train A Residual Heat Removal with train B out of service on July 12 C Unit 1 train A Boron Injection Flowpath with train B out of service on September
To evaluate the operability of the selected trains or systems under these conditions, the inspectors verified correct valve and power alignments by comparing observed positions of valves, switches, and electrical power breakers to the procedures and drawings listed in the Attachment to this report. In addition, the inspectors used the operator aid computer to determine whether system parameters were as expected for the system and plant conditions, and whether equipment status shown for inaccessible equipment supported operability of the system.
b. Findings No findings of significance were identified.
1R05 Fire Protection a. Inspection Scope For the areas identified below, the inspectors reviewed the licensees control of transient combustible material and ignition sources, fire detection and suppression capabilities, fire barriers, and any related compensatory measures, to verify that those items were consistent with UFSAR Section 9.5.1, Fire Protection System, and the fire protection program as described in the Design Basis Specification for Fire Protection, MCS-1465.00-00-0008. The inspectors walked down accessible portions of each area as well as reviewed results from related surveillance tests, and reviewed the associated pre-fire plan strategy, to verify that conditions in these areas were consistent with descriptions of the areas in the Design Basis Specification. Documents reviewed during this inspection are listed in the Attachment to this report.

The inspectors reviewed the McGuire Unit 1 Inservice Inspection report dated June 30, 2004, which documented one recordable indication observed during the Unit 1 1EOC16 refueling outage. The indication was recorded on an integral attachment weld, ISI item number C03-010-005, on the Excess Letdown Heat Exchanger Support. The inspectors reviewed records of the PT exams, Indication Evaluation Report, Work Order, three Problem Investigation Processes, expanded samples, and corrective actions performed on this weld during the last outage.
The inspectors also reviewed two welding activities: Minor Modification MD 100040 and Work Order 9869901 to weld sleeves in stuffing box for valve 1SM0001AB; and Work
Order 98697084 for a socket weld repair for weld number CFIFWLT6010-18 of Feedwater System to determine if the welding process and examinations were performed in accordance with ASME Section XI repair/replacement requirements. The inspectors reviewed drawings, work instructions, weld process sheets, weld travelers, pre-heat requirements and PT records for welding of ASME Class 2 pressure boundary welds.
The inspectors reviewed activities related to inspection of the Unit 1 reactor pressure vessel (RPV) lower head penetrations. The guidelines and criteria for the inspection were provided in NRC Bulletin 2003-02, Leakage From Reactor Pressure Vessel Lower Head Penetrations and Reactor Coolant Pressure Boundary Integrity and the licensees response to the bulletin. The inspectors reviewed the Work Order 98725139, inspection data documented in the procedure dated September 20, 2005, Rx Vessel Bottom Head Bare Metal Inspection, Rev. 2 , and Problem Investigation Process 05-04275.
The inspectors reviewed implementation of the licensees Boric Acid Corrosion Control program to determine if commitments made in response to Generic Letter 88-05 and Bulletin 2002-01 were being effectively implemented. The inspectors reviewed boric acid leakage screening reports, evaluations, and dispositions. The inspectors selected ten locations where leaks were previously identified inside the containment by the licensees engineers and performed a walkdown to verify the leaks were properly assessed and corrective actions were implemented. The inspectors also performed an independent walkdown to look for additional indications of leakage, that had not been identified by the licensee. The inspectors reviewed work order 98356351, which was written to address several inactive leaks identified as a result of this walkdown.
A sample of ISI issues in the licensees corrective action program were reviewed to confirm that problems were being identified and placed in the corrective action program, and appropriate corrective action were being initiated. The inspectors reviewed the following indication evaluation reports from visual exams and disposition:
- Support 1MCA-NS-H36 for a 1/16" gap found around the anchor bolts for two base plates.

and in order to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensees corrective action program. This review was accomplished by reviewing hard copies of condition reports, attending daily screening meetings, and accessing the licensees computerized database.
.2 Annual Sample Review a. Inspection Scope The inspectors selected PIP M-04-847 for detailed review. This PIP was initiated for violation 2 identified in NRC Inspection Report 05000369,370/2004003, which was a severity level IV non-cited violation of 10 CFR 50.71e for failing to update the UFSAR as required for a license amendment issued on June 6, 1989, to place the fire protection program including the Standby Shutdown Facility (SSF) in the UFSAR. The inspectors reviewed this report to verify that the licensee identified the full extent of the issue, performed an appropriate evaluation, and specified and prioritized appropriate corrective actions. The inspectors evaluated the report against the requirements of the licensees corrective action program as delineated in corporate procedure NSD 208, Problem Identification Process; and for fire protection, as required by McGuire operating license condition 2.C.4 and the licensees fire protection program contained in document MCS-1465.00-0008, Design Basis Specification for Fire Protection. Because this PIP was a category 4 and required no problem evaluation, the inspectors reviewed selected license amendments and other NRC violations that implicated UFSAR accuracy, to determine the extent of condition for the UFSAR accuracy problem, and to determine whether the
licensees corrective actions were correcting the problem. The selected violations, and their associated PIPs, and the selected license amendments are listed in the Attachment. The inspectors also reviewed associated approved UFSAR change packages and the April 6, 2004 UFSAR Revision in determining the effectiveness of the licensees corrective actions. In addition, the inspectors reviewed the licensees submittal of February 28, 2005, and the NRC response of June 8, 2005, related to the licensees proposed implementation of 10 CFR 50.48(c) (NFPA 805 rule) to determine its effect on the findings identified below.
b. Observations and Findings (1) Failure to take timely corrective action for previous Failure to Update UFSAR for GL 86-10 license amendment Introduction: The inspectors identified untimely corrective action to update the UFSAR related to the SSF. This issue was originally identified on February 17, 2004, and on August 3, 2005, no corrective action had been taken to include the SSF in the UFSAR either by revision or approved change package for the next revision.
Description: The inspectors identified, on August 3, that the licensee had not taken any action to revise the UFSAR in response to violation 2 identified in NRC Inspection Report 05000369,370/2004003. The violation was against 10 CFR 50.71(e) for failing to update the UFSAR as required for a license amendment issued on June 6, 1989, to place the fire protection program including the SSF in the UFSAR. The licensee opened PIP M-04-847 to address this issue. However, the assigned corrective action was closed without taking any action with a justification that NFPA 805 actions would update the licensing basis in the future. The inspector found that no action had been taken on this PIP, but that it referenced PIP M-04-4543, initiated for fire protection programmatic health improvement. Although PIP M-04-4543 initiated a review of UFSAR section 9.5.1 and the fire protection program against original license commitments, the inspectors found that the corrective actions to date did not address the violation. The inspectors concluded that no action had been taken based on the fact that the current UFSAR revision (April 6, 2004) did not include the fire protection program or SSF, nor was there an approved change package for the October 2005 revision, and that the corrective action to update the UFSAR had been closed.
Analysis: The issue was determined to be a severity level IV violation in NRC IR 05000369,370/2004003. This issue was considered for being a cited violation in accordance with section VI.A.1 of the NRC Enforcement Policy. However, because the licensee completed adequate corrective action and adequately determined the cause prior to the end of the inspection period, no additional information would be gained from the licensee providing a written response. This finding involved the crosscutting aspect of Problem Identification and Resolution.
Enforcement: McGuire operating license condition 2.C.4 states that the licensee shall maintain in effect and fully implement all provisions of the approved fire protection program as described in the Final Safety Analysis Report, as updated, for the facility and as approved in the NRC Staffs McGuire Safety Evaluation Report (NUREG-0422 )
and its supplements. McGuire UFSAR section 9.5.1 states that the fire protection plan
is contained in document MCS-1465.00-0008, Design Basis Specification for Fire Protection. The Fire Protection Plan states, in Appendix A, Section C, Quality Assurance, that the station directives will implement the fire protection quality assurance program. The quality assurance topical report, Duke-1-A, incorporates fire protection into the plant corrective action program and states that problems will be identified and corrected. Procedure NSD 208, Problem Investigation Process, implements that requirement. Contrary to the above, from February 17, 2004 to August 3, 2005, the licensee did not take any action to revise the UFSAR to include a description of the SSF as originally required for a June 6, 1989, license amendment. This issue is in the licensees corrective action program as PIP M-05-3645. Licensee corrective actions to prepare and approve a UFSAR change and determine the cause of this failure were complete by the end of the inspection period and were determined to be adequate.
Therefore, the failure to take corrective action to update the UFSAR for the SSF is characterized as a non-cited violation consistent with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000369,370/2005004-01, Failure to Take Timely Corrective Action to Update the UFSAR for the SSF.
(2) Failure to update UFSAR for license amendment 169/151 on RCS leak detection instrumentation Introduction: A non-cited violation was identified for failure to update the UFSAR as required by 10 CFR 50.71(e) related to inclusion of the license amendment request safety analysis information pertaining to the use of alternative instrumentation and procedures, instead of seismic qualification, for the Containment Atmosphere Particulate Monitors.
Description: The inspectors discovered, on July 29, 2005 that the licensees UFSAR did not contain key information from its March 4, 1996 license amendment request that the NRC used for approval, on July 30, 1996, of license amendment 169 for Unit 1 and license amendment 151 for Unit 2. The licensee requested that an alternative to regulatory position C.6 of Regulatory Guide 1.45 be granted in relation to the requirement for seismic qualification of the Containment Atmosphere Particulate Radiation Monitors (CAPRMs). The NRC approved the request based on the licensee showing that adequate instrumentation and procedures will be available to assess conditions inside containment following a seismic event comparable to a Safe Shutdown Earthquake. The licensees UFSAR section 5.2.7.1 identified that Regulatory Guide 1.45, Position C.6 is interpreted as follows: The Leakage Detection System is capable of performing its function following seismic events that do not require plant shut down.
The airborne particulate radioactivity monitoring equipment is not seismically qualified to function through the safe shutdown earthquake. The UFSAR makes no mention of the alternative instrumentation and procedures that were provided as the basis for the license amendment request approval.
Analysis: The inspectors found that the issue was greater than minor because the failure to include in the UFSAR the alternative methodology for RCS leakage detection after a seismic event with unqualified CAPRMs, as described in the licensees safety analysis, was material to the acceptability of the license amendment requests. The inspectors found no subsequent changes made to the facility that were based on the erroneous information in the UFSAR section. Consequently, this issue was considered to meet the
criteria of a severity level IV violation. This finding involved the crosscutting aspect of Problem Identification and Resolution.
Enforcement: 10 CFR 50.71(e) requires that licensees shall update periodically the FSAR originally submitted as part of the application for the operating license, to assure that the information included in the report contains the latest information developed.
This submittal shall include the effects of all the changes necessary to reflect information and analysis submitted to the Commission by the licensee or prepared by the licensee pursuant to Commission requirement since the submittal of the original FSAR, or as appropriate the last update of to the FSAR under this section. Contrary to this requirement, prior to July 29, the licensee had not updated the UFSAR to include the latest information developed in relation to the containment air particulate monitors.
The licensee did not include the alternative methodology for RCS leakage detection related to the CAPRMs after a seismic event, as described in the licensees safety analysis, which was the basis for acceptability of the license amendment requests. The failure to update the UFSAR for the CAPRMs as required by 10 CFR 50.71(e) is characterized as a severity level IV violation and is being treated as an NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy: NCV 05000369,370/2005004-02, Failure to Update the UFSAR for CAPRMs. This issue is in the licensees corrective action program as PIP M-05-3541.
4OA3 Event Follow-up
.1 (Closed) Licensee Event Report (LER) 05000370/2005-06, Failure of Containment Floor and Equipment (CFAE) Sump Discharge Outside Containment Isolation Valve.
On July 28, 2005, the licensee determined that valve 2WL-65B had likely been inoperable during the previous operating cycle due to the valve not being fully closed.
This valve is a motor operated diaphragm valve and is one of two redundant containment isolation valves for the CFAE discharge line. The period of inoperability exceeds that allowed by TS. This condition was also reported as a condition that reasonably could have prevented the fulfillment of a safety function as there were short periods of inoperability of the redundant isolation valve 2WL-64A during unavailability of its emergency power source. This 2WL-65B inoperability was caused by manual handwheel operation of the valve on September 29, 2003 when the valve was opened to pump down the CFAE sump during 2EOC14. Due to inadequate procedural guidance and a lack of understanding of the unique design limitations of motor operated diaphragm valves, the manual opening affected the Rotork actuator limit switch adjustment so that when the valve was subsequently electrically closed, it did not fully close.
The inspectors reviewed the licensees apparent cause evaluation and corrective actions which included operations training for the design limitations of manual operation of diaphragm motor operated valves and providing procedural guidance for the proper operation of these valves. The licensee is also evaluating the need for local leak rate testing following manual operation of these valves. The inspectors determined that the licensees corrective actions were appropriate. The enforcement aspects of this licensee-identified violation are discussed in Section 4OA7 of this report. This LER is closed.
.2 (Closed) LER 05000370/2005-04, Actuation of Main Steam Isolation Valves Due to Human Error. This event resulted from a failure to follow procedure OP/2/A/6100/SU-19, Heatup to 557o F. The result was an unplanned ESF actuation in Mode 3 during startup with essentially no steam flow. Since the safety function of the actuation is to mitigate a steam line break and is based on steam line pressures, the unplanned ESF actuation provided no safety significant mitigating action because an operator human performance error caused the actuation pressure parameters to exist when a steam line break had not occurred. Consequently, the inspectors concluded that the ESF actuation was of minor safety significance. This LER is closed.
4OA5 Other Activities
.1 Initial Cask Loading and Storage Observation a. Inspection Scope The inspectors reviewed the Unit 2 documentation package for the Casks listed below that were created using procedure XSM-006, Workplace Procedure For Selecting Spent Fuel For Use Of NAC-UMS System at McGuire and Regulatory Guide 3.54, Spent Fuel Heat Generation to verify that the selected fuel assemblies and burnable poison inserts met the requirements for insertion in dry cask storage.
- NAC-UMS TSC-MNZ-003 (Document Control NO MCEI 0400-153),
- NAC-UMS TSC-MNZ-004 (Document Control NO MCEI 0400-154),
- NAC-UMS-TSC-MNZ-005 (Document Control No. MCEI 0400-155)
The inspectors reviewed the Cask loading verification video tapes for each of the above Casks to verify that the alpha-numeric identification numbers stamped on the loaded fuel assemblies and burnable poison assemblies matched the identification numbers used in the documentation package as required by procedure OP/0/A/6550/028, NAC UMS Fuel Assembly Loading/Unloading Procedure. The Casks were loaded on 7/12/05, 7/26/05, and 8/9/05, respectively. The inspectors reviewed selected licensee activities as specified in procedure MP/0/A/7650/212, Loading Spent Fuel Assemblies Into NAC-UMS Casks, to verify that activities were being accomplished in accordance with procedural requirements.
b. Observations and Findings No findings were identified. Overall, the licensee established and maintained adequate oversight for the dry cask storage evolution. Technical Specifications requirements and acceptance criteria as outlined in the FSAR for the NAC-UMS casks and the procedures were followed appropriately. The licensee encountered a recurring problem in completing the vacuum drying process of the spent fuel storage cask within the NAC-UMS technical specification allowed time of 52 hours6.018519e-4 days <br />0.0144 hours <br />8.597884e-5 weeks <br />1.9786e-5 months <br />, 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br />, and 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> respectively, following fuel loading for each cask. The previous occurrences were discussed in IR 05000370/2004009 and 05000370/2005002. After returning the cask to in-pool cooling for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, the licensee reestablished vacuum drying and was able to
meet the TS requirements.
.2 Operational Readiness of Offsite Power (Temporary Instruction (TI) 2515/163)
This TI was completed in Inspection Report 05000369,370/2005003. However, after NRC headquarters review of the information provided, additional information related to the TI was requested. The inspectors collected this information from licensee discussions, site procedures, and other licensee documentation. The inspection results was provided to the headquarters staff for further analysis.
.3 (Closed) TI 2515/160, Pressurizer Penetration Nozzles and Steam Space Piping Connections in U.S. Pressurized Water Reactors (NRC Bulletin 2004-01) - Unit 1 a. Inspection Scope The inspectors reviewed procedures and records documenting activities relative to inspection of the Unit 1 pressurizer penetrations to verify that the licensee complied with commitments made in the licensees response on July 27, 2004 and supplement response on September 21, 2004 to NRC Bulletin 2004-01, Inspection of Alloy 82/182/600 Materials Used in the Fabrication of Pressurizer Penetrations and Steam Space Piping Connections at Pressurized Water Reactors. The inspectors reviewed the records documenting the results of visual inspections performed on the welds including one surge nozzle, one spray nozzle, one relief nozzle, three safety nozzles, and one manway insert. The inspectors also independently performed a bare metal visual examination of surge nozzle to determine the effectiveness of the inspection. The surge nozzle on the bottom of the pressurizer was included in the licensee inspection, but not required by the bulletin. The guidelines for the inspection were provided in NRC temporary instruction (TI) procedure TI 2515/160.
b. Findings There were no indications of boron leakage or penetration degradation in any pressurizer connections examined by the licensee during their inspections.
TI 2515/160 Reporting Requirements:
a. For each of the examination methods used during the outage, was the examination:
1. Performed by qualified and knowledgeable personnel?
Yes. The bare-metal visual examinations of the pressurizer penetrations were conducted by licensee NDE inspection personnel certified as ISI VT-1, 2, and 3 Level II who had been trained and qualified in accordance with applicable visual inspection procedures for VT - 1, 2, and 3, and were certified in accordance with ASME Code requirements.
2. Performed in accordance with demonstrated procedures?
Yes. The visual inspections were conducted in accordance with Duke Procedure QAL-14, Rev. 25, Inservice Inspection (ISI) Visual Examination, VT-3, VT-3C, and VT-3MC and Supplements of the Work Order 98683511 and Procedure MP/0/A/7700/80, Rev. 008, Inspection, Evaluation, and Cleanup of Boric Acid on Plant Materials. The inspectors reviewed the inspection procedure and verified that it had been reviewed and approved in accordance with the licensees procedure review process and NRC requirements.
3. Able to identify, disposition, and resolve deficiencies?
The inspectors reviewed the licensees procedures controlling the visual examination and determined that the procedure provided adequate guidance to identify, disposition and resolve identified deficiencies in the pressurizer penetrations. The licensees examiner was a qualified ISI VT-1, 2, and 3 Level II Examiner.
4. Capable of identifying the leakage in pressurizer penetration nozzle or steam space piping components, as discussed in NRC Bulletin 2004-01?
The visual examination method was capable of identifying leakage through and around areas adjacent to the pressurizer penetrations.
b. What was the physical condition of the penetration nozzle and steam space piping components in the pressurizer system?
Prior to the visual inspections, insulation was removed from the pressurizer head and penetrations. The areas were free of debris, dirt, boron from other sources. The physical layout of the area was congested, however, with the insulation removed, NDE inspection personnel were able to perform visual inspections around 360E of the circumference of each penetration. There were no viewing obstructions.
c. How was the visual inspection conducted?
Inspections were conducted by direct visual by NDE inspection personnel.
d. How complete was the coverage?
360E around the circumference of all the nozzles.
e. Could small boron deposits, as described in the Bulletin 2004-01, be identified and characterized?
With the lighting available, boron deposits, as described in the bulletin, could have been readily identified and characterized. No boron deposits were found.
f. What material deficiencies were identified that required repair?
No material deficiencies were identified that required repair.
g. What, if any, impediments to effective examinations, for each of the applied methods, were identified?
No significant items were encountered that impeded the bare metal examinations of the pressurizer penetrations.
h. If volumetric or surface examination techniques were used for the augmented inspections examinations, what process did the licensee use to evaluate and dispose any indications that may have been detected as a result of the examinations?
No indications were identified. The licensee stated that Problem Investigation Process would be used to evaluate and dispose any indications if found.
i. Did the licensee perform appropriate follow-on examinations for indications of boric acid leaks from pressure-retaining components in the pressurizer system?
No indications of leakage were identified during the current outage 4OA6 Meetings, Including Exit On October 6, 2005, the resident inspectors presented the inspection results to Mr. G.
Peterson and other members of his staff. The inspectors confirmed that proprietary information was not provided or examined during the inspection.
4OA7 Licensee-Identified Violations The following finding of very low significance was identified by the licensee and is a violation of NRC requirements which meets the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600 for being dispositioned as a NCV.
- TS 3.6.3 specifies that each containment isolation valve be operable in Modes 1, 2, 3, and 4 and TS 3.6.3, Condition A specifies if one containment isolation valve is inoperable, the affected penetration flow path shall be isolated within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> and verified to be isolated once per 31 days. On September 29, 2003, containment isolation valve 2WL-65B was manually opened by operations using the handwheel of the actuator to allow pumping down the Containment Floor or Equipment Sump (CFAE) during a period when power was removed from the actuator. The valve was rendered inoperable as the valve was improperly opened too many turns which affected its Rotork actuator limit switch settings, so that when it was subsequently electrically stroked on October 6, 2003, it did not fully close. The licensee did not discover this condition until July 2005 during their investigation of the valve failing a local leak rate test during 2EOC15.
Contrary to TS 3.6.3, Condition A, the licensee failed to initially isolate the flow path and did not verify isolation every 31 days during the period of inoperability.
This issue was determined to be of very low safety significance based on the screening criteria found in MC 0609, Appendix H, Containment Integrity Significance Determination Process, approach for assessing Type B findings at power. The issue was screened as having very low safety significance (Green)
as the failure of 2WL-65B to fully close did not affect the likelihood of core damage and did not represent a contributor to the large early release frequency (LERF). This issue was documented in the licensees corrective action program as PIP M-05-1794.
