SUBJECT:

BEAVER VALLEY POWER STATION - NRC INTEGRATED INSPECTION REPORT 05000334/2006003 AND 05000412/2006003

Dear Mr. Lash:

On June 30, 2006, the United States Nuclear Regulatory Commission (NRC) completed an inspection at your Beaver Valley Power Station Units 1 and 2. The enclosed integrated inspection report documents the inspection findings, which were discussed on July 24, 2006, 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 Commissions rules and regulations and with the conditions of your license.

The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.

Based on the results of this inspection, the NRC has identified one (1) NRC-identified finding of very low safety significance (Green). This finding was determined to involve a violation of NRC requirements. However, because of the very low safety significance and because the issue has been entered in the 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 of the findings 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 Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001; with copies to the Regional Administrator Region I; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at Beaver Valley.

In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, and 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 NRCs document system (ADAMS). ADAMS is accessible from the NRC Website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room). We appreciate your cooperation. Please contact me at 610-337-5200 if you have any questions regarding this letter.

SUMMARY OF FINDINGS

IR 05000334/2006003, IR 05000412/2006003; 04/01/2006 - 06/30/2006; Beaver Valley Power

Station, Units 1 & 2; Problem Identification and Resolution.

The report covered a 3-month period of inspection by resident inspectors, regional reactor inspectors, and a regional health physics inspector. One (Green) non-cited violation (NCV) was identified. The significance of most findings is indicated by their color (Green, White, Yellow,

Red) using Inspection Manual Chapter (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 NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process,

Revision 3 dated July 2000.

NRC-Identified and Self-Revealing Findings

Cornerstone: Barrier Integrity

C

Green.

The inspectors identified an NCV of 10 CFR 50, Appendix B, Criterion 16, for failure to perform adequate operability evaluations for degraded components to assure off-site dose consequences are bounded in the radiological safety analysis for a Steam Generator Tube Rupture (SGTR) event.

Specifically, some barrier integrity components (HCV-1MS-104 and 1MS-26,

Atmospheric Steam Dump Valve(s), and Steam Generator Safety Valves) were degraded (leaking) and FENOC did not quantify and evaluate the current leakage regarding additional radiological dose consequences during a design basis accident (SGTR event). The licensee entered this deficiency into their corrective action program, assessed the magnitude of additional steam leakage that would be permitted before licensing basis dose results are exceeded, and determined the present leakage is bounded by current analyses.

This finding is more than minor because it was associated with the Structures,

System, and Component (SSC), and Barrier Performance Attribute of the barrier integrity cornerstone and affected the objective of providing reasonable assurance that the physical design barrier (containment) protected the public from radionuclide releases caused by accidents or events (SGTR). The finding is of very low safety significance because although degraded, the leaking residual heat release valve and other components (e.g., safety valves and atmospheric dump valves) are not important to Large Early Release Frequency (LERF) and do not affect Core Damage Frequency (CDF). The cause of this finding is related to the corrective action program component of the Problem Identification and Resolution (PI&R) cross-cutting area, in that degraded components were not adequately evaluated to assure proper operability was determined. (Section 4OA2)

Licensee-Identified Violations

REPORT DETAILS

Summary of Plant Status:

Unit 1 began the inspection period shut down for a significant refueling outage during which the reactor vessel closure head and all three steam generators were replaced.

On April 19, 2006, reactor startup and low-power physics testing commenced, with 100% full power reached on April 23rd. On May 19th, power was reduced to 10%, and the turbine-generator taken off-line to perform turbine-shaft balancing. The Unit returned to full power on May 21st. On May 26th, a failure within Solid State Protection System (SSPS) required a shut down to comply with Technical Specifications (TS). On May 27th, the SSPS was returned to service, the reactor startup commenced, and full power was reached on May 28th. The Unit operated at or near full power for the remainder of the inspection period.

Unit 2 began the inspection period operating at 100% power, but automatically tripped off-line on April 2nd, due to a failure associated with the main unit generator exciter.

Following repairs, the Unit returned to full power on April 7th. On April 11th, operators entered TS 3.0.3 and reduced power to 18%, due to an inadvertent wetting of the charcoal filter bed of the Supplemental Leak Collection and Release System. Following completion of repairs, the Unit was returned to full power on April 12th. The Unit down-powered for one hour to 86% on June 24th for turbine control valve testing. Upon return to full power, it continued to operate at full power for the remainder of the inspection period.

b. Findings

There were no findings of significance identified.

1R08 Inservice Inspection

a. Inspection Scope

The inspector assessed the inservice inspection (ISI) activities using the criteria specified in the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code,Section XI. The inspector reviewed documentation and interviewed personnel to verify that the activities were performed in accordance with the ASME Boiler and Pressure Vessel Code Section XI requirements. The sample selection was based on the inspection procedure objectives and risk priority of those components and systems where degradation would result in a significant increase in risk of core damage.

The inspector reviewed a sample of condition reports to assess the licensees effectiveness in problem identification and resolution. The specific ISI activities selected for review included:

  • A visual examination (VT-2) of the pressurizer top head nozzles (A, B, C and D)and the spray nozzle (E)
  • Boric acid corrosion control leak inspection results and mode hold resolution forms for the A RHR pump discharge check valve and the RCP 1C seal supply drain valve
  • UT erosion/corrosion examination of piping line 3"-RC-107-1502-Q1, located between motor-operated valve MOV-IRC-535 and the power-operated relief valve block valve, and associated condition report (CR)
  • A liquid penetrant examination of an ASME Section XI IWB Category B-J pressure-retaining weld, DG-56-3-F-03, and associated condition report, and a Ten-Year Plan Change Request The inspector interviewed the boric acid corrosion control program owner and sampled the photographic database of all examined areas to verify that visual inspections emphasized locations where boric acid leaks can cause degradation of safety significant components. The inspector also reviewed a sample of items on the mode hold list, as well as the procedures being used for visual inspection for evidence of boric acid leakage. The inspector confirmed that sampled condition reports were assigned corrective actions consistent with the requirements of the ASME Code and 10 CFR 50 Appendix B, Criterion XVI.

In addition, the inspector reviewed non-destructive examination (NDE) certifications for inspectors performing the above listed examinations, and for the Level III reviewer. The inspector also reviewed the procedures used to complete the reactor vessel lower head penetration inspections (bottom-mounted penetrations). The inspector observed the accessibility to the penetrations and the lower head insulation design factored into the design of the newly acquired camera and lighting equipment. Documents reviewed are listed in the Attachment.

b. Findings

1R13 Maintenance Risk Assessment and Emergent Work Control

a. Inspection Scope

The inspectors reviewed the scheduling and control of eight activities, and evaluated the effect on overall plant risk. This review was conducted to ensure compliance with applicable licensee and regulatory criteria contained in 10 CFR 50.65(a)(4). Documents reviewed during the inspection are listed in the Attachment. The inspectors reviewed the planned or emergent work for the following activities:

  • On April 10, 2006, Unit 1 entered a planned yellow risk status due to the implementation of ECP No. 02-0269, Rev. 1, Piping Changes to 1EE-P-2A and 2B Lube Oil Circulation Pump Discharge Lines for the Unit 1 No. 1 EDG.
  • On May 4, 2006, operators on Unit 2 identified a condition where local control of valve 2-SIS-HCV868A was lost. The valve is operated to establish an alternate charging path when required by emergency procedure ES-1.2, Post LOCA Cooldown and Depressurization. Work Order 200208344 was accomplished to correct the deficiency.
  • On May 4, 2006, Unit 2 entered a planned yellow risk status to perform 2MSP-1.04-1, Solid State Protection System Train A Bi-Monthly Test, Issue 4, Rev. 30; and to replace four universal logic cards in accordance with Work Order 200205488.
  • On May 10, 2006, the inspectors reviewed the licensee evaluation (Green risk)and activities associated with an emergent test on the dedicated emergency feedwater pump, performed in accordance with 1OST-24.7, Rev. 13, Dedicated Auxiliary Feed Pump [1FW-P-4] Test.
  • May 31, 2006, Unit 1 entered a planned "yellow" risk due to the replacement of the Refueling Water Storage Tank (RWST) Return Isolation Valve, PC-47.
  • On June 5, 2006, the inspectors reviewed the licensee evaluation and preparations associated with a planned yellow risk status to accomplish maintenance activities on the Unit 2 Quench Spray Pump P21A.
  • The inspectors reviewed condition reports CR-06-0266 and 06-02998, which addressed deficiencies in the shutdown risk assessment during the Unit 1 steam generator replacement outage.
  • The inspectors reviewed CR 06-03863, which details operational challenges presented by a mechanical seal leak on 2CDS-P22A.

b. Findings

No findings of significance were identified.

1R14 Personnel Performance During Non-routine Plant Evolutions

a. Inspection Scope

The inspectors reviewed two events that demonstrated personnel performance in coping with non-routine evolutions and transients. The inspectors observed operations in the control room and reviewed applicable operating and alarm response procedures, technical specifications, plant process computer indications, and control room shift logs to evaluate the adequacy of FENOC's response to these events. The inspectors also verified the events were entered into the corrective action program to resolve identified adverse conditions. Documents reviewed during the inspection are listed in the

.

  • Unit 1: On May 26, 2006, at 11:30 a.m., during performance of 1MSP-1.05-I, Solid State Protection System (SSPS) Train B Bi-Monthly Test, the surveillance indicated unsatisfactory results while performing the Memories Function Test (CR-06-03525). Technical Specifications required a plant shutdown to Mode 3.

The Unit was placed in Mode 3 as required, Solid State Protection System troubleshooting and repairs were completed with assistance from the nuclear steam supply system vendor (Westinghouse). All post-maintenance testing was completed satisfactory.

  • Unit 2: On April 11, 2006, at 9:24 a.m., multiple unexpected Fire Protection System Deluge Valve actuations resulted in wetting of both charcoal main filter banks required by TS 3.7.8.1. As a result, TS 3.0.3 was entered, requiring a unit shutdown within the next 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />. Unit 2 power was reduced to 18 percent over the next 5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> and preparations were made to disconnect the unit from the grid. The downpower was terminated at approximately 18%, due the licensees receipt of a Notice Of Enforcement Discretion (NOED) from the NRC, which allowed for a fixed time window for restoration of the components.

URI 2006-003-01 was opened to track enforcement actions pending NRC review of the event.

The inspectors monitored licensee activities in the control room including use of procedures to reduce power, technical specification adherence, NRC notification of the event, and operator actions during the power reduction. A post-event review of Unit 2 operator logs confirmed inspector observations during the event.

The unexpected Fire Protection System Deluge Valve actuations occurrence was entered into the licensees corrective action process for evaluation and resolution.

The inspectors noted that the licensees apparent cause was most likely due to a ground that occurred on the non-safety related 125VDC bus 2-5 / 2-6, which resulted in a surge that actuated certain fire protection relays. The plant risk associated with the inadvertent actuation of the fire protection deluge system is considered to be very low. Since no violation of NRC requirements were identified, beyond the TS implications associated with the NOED, this URI is closed. URI 05000412/2006003-01, Beaver Valley Unit 2 NOED for Two Trains of SLCRS OOS (06-1-01).

b. Findings

No findings of significance were identified.

1R15 Operability Evaluations

a. Inspection Scope

The inspectors evaluated the technical adequacy of selected operability determinations (OD), Basis for Continued Operations (BCO), or operability assessments, to verify that determinations of operability were justified, as appropriate. In addition, the inspectors verified that TS limiting conditions for operation (LCO) requirements and UFSAR design basis requirements were properly addressed. Documents reviewed are listed in the

. This inspection activity represents seven samples of the following issues:

  • An OD associated with one of the two upper snubbers on the Unit 1 C Steam Generator (RC-HC-10C), as documented in CR 06-02913, regarding a hydraulic fluid leak first identified on April 16, 2006. The inspectors assessed the adequacy and acceptability of FENOC's conclusions in the OD that the current leak rate (1 drop every 2 minutes) is acceptable and that the snubber will remain fully functional. The inspectors evaluated the snubber reservoir level impact calculation, the coping strategy, and the conclusions of the seismic and combustible loading analyses.
  • On May 8 - 10th, the inspectors reviewed an OD associated with Unit 1 Quench Spray System flow lines that were potentially not periodically tested or inspected, as documented in CR 06-03127. The inspectors assessed the adequacy and acceptability of FENOC's operability assessment and verified that appropriate technical issues were addressed.
  • On May 9th, the inspectors reviewed licensee actions associated with potential reportability of issues identified in CRs 06-03134 and 06-03199. These CRs, addressed a charcoal sample iodine removal efficiency test failure on SLCRS Filter Bank 2HVS-FLTA205A, and charcoal sample testing for Filter Banks 2HVS-FLTA205A, 205B, 208B.
  • On June 5th, the inspectors reviewed licensee actions associated with CR 06-03239, which included the adequacy of an engineering analysis of discharge pressure for 1-FW-P-4, during the performance of 1OST-24.7 on May 9, 2006.
  • On June 7 and 8, 2006, the inspectors reviewed licensee actions associated with the operability determination for CR 06-03630, which detailed a pinhole leak on piping for Unit 2 vacuum breaker 2SWS-486.
  • The inspectors reviewed the Engineering Evaluation associated with CR 06-02872, which addressed the licensees exceedance of a 320 degree differential temperature limit for the pressurizer spray line. While the 322°F differential temperature resulted in a small, two degree exceedance of the limit in Section 8.4 of the License Requirements Manual (LRM), an evaluation was required and concluded that the out-of-limit condition did not affect the structural integrity of the pressurizer based on the bounding analysis of record, WCAP-15351, Evaluation of Pressurizer Transients Based on Plant Operations for Beaver Valley Unit 1.
  • The inspectors reviewed licensee actions associated with an Operational Decision Making Issue (ODMI) evaluation, due to indications that a potential loose part was located in the secondary side of the C steam generator. The ODMI included data that indicated a potential loose part was present since steady-state 100 percent power operations was reached on April 27, 2006, following refueling outage No.17. The inspectors assessed the adequacy and acceptability of FENOCs review, as contained in the ODMI summary document Continued Plant Operation With A Loose Part Indication In The Secondary Side Of 1RC-E-1C, Rev. 3 (including previous revisions). The review included applicable condition reports 06-03091, 06-03092, 06-03620, 06-03618 and 06-03709.

b. Findings

No findings of significance were identified.

a. Inspection Scope

During the period April 3 - 7, the inspector conducted the following activities to verify that the licensee was properly implementing physical, administrative, and engineering controls for access to locked high radiation areas and other radiologically controlled areas during the Unit 1 refueling outage and Unit 2 power operations. Implementation of these controls was reviewed against the criteria contained in 10 CFR 20, relevant technical specifications, and the licensees procedures. This inspection activity represents completion of eight samples relative to this inspection area.

Plant Walkdown and RWP Reviews During the Unit 1 refueling outage, the inspector identified exposure-significant work activities being conducted in the reactor building and primary auxiliary building. Specific work activities included removal of scaffolding and temporary shielding from the reactor building, installation of a ventilation system on the reactor head, installation of level sensing lines and insulation on the steam generators, air-operated valve repair/testing, and various outage support activities. The inspector reviewed radiation survey maps and radiation work permits (RWP) associated with these activities to determine if the associated controls were acceptable.

The inspector toured accessible radiological controlled areas, including the Unit 1 reactor building, the Unit 1 and Unit 2 primary auxiliary buildings, Unit 1 fuel handling building, Unit 2 condensate polishing building, Unit 1 decontamination building, Unit 1 waste handling building, and the old steam generator/reactor head storage mausoleum.

With the assistance of the ALARA Supervisor, the inspector performed independent surveys of selected areas in these buildings to confirm the accuracy of survey maps and the adequacy of postings. The inspector confirmed that environmental dosimeters were properly located on the mausoleum and that the building was secured.

In evaluating RWPs, the inspector reviewed electronic dosimeter dose/dose rate alarm setpoints to determine if the setpoints were consistent with the survey indications and plant policy. The inspector verified that the workers were knowledgeable of the actions to be taken when the dosimeter alarms or malfunctions for tasks being conducted under selected RWPs. Work reviewed included RWP No. 106-8005, Steam Generator Replacement Project (SGRP) scaffolding removal; RWP 106-8006, SGRP restoration; RWP 106-8011, SGRP temporary shielding removal; RWP 106-8017, reactor head reassembly; RWP 106-4009, reactor cavity draindown/decontamination; and RWP 106-4003, outage mechanical maintenance.

The inspector reviewed RWPs and associated instrumentation and engineering controls for potential airborne radioactivity areas located in the reactor building and primary auxiliary building. The inspector confirmed that no worker received an internal dose that exceeded 10 mrem due to airborne radioactivity when performing outage-related tasks.

The inspector reviewed personnel contamination event reports and the dose assessment methodology for tasks potentially resulting in internal exposures to confirm the accuracy of the results. Tasks reviewed included reactor building demobilization, insulation removal, and decontamination activities.

Problem Identification and Resolution The inspector reviewed elements of the licensees corrective action program related to controlling access to radiologically controlled areas to determine if problems were being entered into the program for resolution. Details of this review are contained in Section 4OA2 of this report.

Jobs-In-Progress The inspector observed aspects of various activities to confirm that radiological controls, such as required surveys, area postings, job coverage, and pre-job RWP briefings were implemented; personnel dosimetry was properly worn; and that workers were knowledgeable of work area radiological conditions. The inspector attended a supervisory meeting that addressed determining the cause and reducing the frequency of personnel contamination events.

High Risk Significant - LHRA and VHRA Controls Keys to locked high radiation areas (LHRA) and very high radiation areas (VHRA) for Unit 1 and Unit 2 were inventoried, and accessible LHRAs and VHRAs were verified to be properly secured and posted during plant tours.

The inspector discussed with radiation protection supervision the adequacy of physical and administrative controls for performing work in high radiation areas including the movement of spent resin for processing and disposal. The inspector verified that any changes to relevant procedures did not substantially reduce the effectiveness and level of worker protection and evaluated the adequacy of pre-requisite communications and authorizations.

Radiation Worker Performance The inspector observed radiation worker and radiation protection technician performance during the installation of a ventilation system on the Unit 1 reactor head, installation of insulation on the steam generators, and the conduct of various outage support activities. The inspector determined that the individuals were aware of current radiological conditions and access controls, and that the skill level was sufficient with respect to the potential radiological hazards and the work performed.

The inspector reviewed condition reports related to radiation worker and radiation protection technician errors, and personnel contamination event reports to determine if an observable pattern traceable to a similar cause was evident.

b. Findings

The evaluation was accomplished by interviewing the Manager-Radiation Protection, the Senior Nuclear Specialist-ALARA, and the Supervisor-ALARA; reviewing ALARA Committee meeting minutes; reviewing Nuclear Oversight field observation reports; and attending an outage planning meeting.

The inspector compared the person-hour estimates provided by various departments and contractors with actual work activity time requirements and evaluated the accuracy of these estimates. Specific jobs reviewed included temporary shielding removal, SGRP scaffolding removal, and reactor reassembly.

The inspector determined if work activity planning included the use of temporary shielding, system flushes, and operational considerations to further control dose.

The inspector evaluated the effectiveness of temporary shielding installed on various components and the effects of reactor coolant system flushes/filtration.

The inspector reviewed personnel contamination event reports and dose assessments for selected personnel who became contaminated while performing outage tasks. The inspector reviewed the effectiveness of the licensees methods for controlling airborne radioactivity concentrations through the use of temporary ventilation systems.

Verification of Dose Estimates and Exposure Tracking Systems The inspector reviewed the assumptions and basis for the annual site collective exposure estimate and the revised Unit 1 outage dose projection.

The inspector reviewed the licensees method for adjusting exposure estimates and re-planning work when emergent work or expanded job scope was encountered. The inspector attended an outage planning meeting, reviewed recent actions of the Station ALARA Committee in monitoring and controlling dose allocations, and interviewed site staff regarding actions to be taken when actual dose approached estimated dose.

The inspector reviewed the licensees exposure tracking system (HIS-20) to determine whether the level of detail, exposure report timeliness and dissemination was sufficient to support the control of collective exposures. Included in this review were departmental dose compilations, specific RWP dose summaries, and individual exposure records.

The inspector reviewed dose and dose rate alarm reports to determine if the dosimeter set points were appropriate for the work area radiological conditions.

Job Site Inspection and ALARA Control The inspector observed various outage activities being performed for re-assembling the reactor head, temporary shielding removal, and scaffolding removal, to verify that radiological controls, such as required surveys, job coverage, pre-job HRA briefings, and contamination controls were implemented; personnel dosimetry was properly worn; and that workers were knowledgeable of work area radiological controls.

The inspector reviewed the exposure of individuals in selected work groups, including contractors, radiation protection, and maintenance crafts to determine if supervisory efforts were being made to equalize dose among the workers.

Source Term Reduction and Control The inspector reviewed the status and historical trends for the Unit 1 source term.

Through review of survey maps and interviews with the Senior Nuclear Specialist-ALARA, the inspector evaluated recent source term measurements and control strategies. Specific strategies being employed at Unit 1 included zinc addition, shutdown chemistry controls, system flushes, and temporary shielding.

Problem Identification and Resolution The inspector reviewed elements of the licensees corrective action program related to implementing the ALARA program to determine if problems were being entered into the program for timely resolution. Condition reports related to dose/dose rate alarms, programmatic dose challenges, and effectiveness in predicting and controlling worker dose were reviewed. Details of this review are contained in Section 4OA2 of this report.

.3 Annual Sample Review

CR-03-05-06503 - Installed Reducing Bushing On 2CHS-E25B Was Not The Correct Material

a. Inspection Scope

The inspectors selected condition report (CR) 05-06503 for detailed review, which was initiated in September 2005, and documented that a steel bushing had been incorrectly installed on the lube oil cooler to the Unit 2 B Charging Pump that required a stainless steel bushing. The inspector reviewed the adequacy and appropriateness of corrective actions to address the installation of incorrect material on a safety-related component.

Documents that were reviewed for this inspection are located in the Attachment.

b. Findings and Observations

No findings of significance were identified.

The inspector noted that the CR had no associated corrective actions beyond the documentation that the steel bushing was replaced with the required stainless steel bushing. The inspector identified that various site program and human performance barriers failed to preclude the installation (and later the identification) of a steel bushing in a component that required stainless steel in accordance with applicable drawing and design documentation. For example, Material & Revision Request No. 4094, utilized during replacement of the bushing from February 2002, contained observations that some site drawings did not detail the reducing bushings, and that they were rusty and weeping moisture, and needed to be replaced in 2R09. The inspectors determined that these were missed opportunities, since design documentation from the vendor manual clearly identified the bushing material as stainless steel. Moreover, since all other site drawings referenced in the work orders during the 2002 and 2005 replacement did not detail the bushing or the material type, the inspector concluded that the vendor manual for the lube cooler could have been reviewed during the work planning process to ensure the correct component was installed on the safety-related charging pump. The inspectors verified that the issue was placed into the corrective action program as CR 06-03948 for resolution.

Specific focus was placed on immediate corrective actions (operability determinations) for CR 06-03726, HCV-1MS-104 and 1MS-26 Leak-by. In addition, related corrective actions for CR 06-03664 and CR 06-03904 were reviewed.

b. Findings

Introduction.

The inspectors identified a Green, non-cited violation of 10 CFR 50, Appendix B, Criterion 16, for failure to perform adequate operability evaluations for degraded components to assure off-site dose consequences are bounded in the radiological safety analysis for a SGTR event.

Description.

On June 6, 2006, condition report (CR) 06-03664 was initiated due to identified leakage past valve 1MS-26, while the licensee was investigating steam leakage to atmosphere past the downstream residual heat release valve HCV-1MS-104.

These two valves provide a boundary isolation function during a steam generator tube rupture (SGTR) event in accordance with 1OM-53A.1.E-3(ISS1C). On June 7, 2006, CR 06-03726 was initiated to evaluate the off-site dose effects from this leakage past HCV-1MS-104, following a SGTR. The CR also requested the evaluation account for any current leakage past the SG atmospheric dump valves and SG safety valves.

Operators reviewed requirements contained in the License Requirements Manual specification LR 6.1 and the associated bases, and concluded that HCV-1MS-104 was operable.

Following discussions with plant personnel, CR 06-03903 was initiated on June 21, 2006, to account for the additional SGTR dose consequences for current leakage past HCV-1MS-104, 1MS-26, and the remaining atmospheric dump and safety valves above the leakage already assumed in the radiological safety analysis. The CR, in part, referenced LR 6.1 Bases and noted the Bases also addressed fully closing on demand as one of the functional requirements of HCV-1MS-104. Operations, after discussions with engineering, documented in CR 06-03903 that HCV-1MS-104 was operable, but degraded. CR 06-03903 further documented that current leakage past degraded components (HCV-1MS-104 and 1MS-26, Atmospheric Steam Dump Valve(s), and Steam Generator Safety Valves) had not been quantified. Stone and Webster was contacted to assess the magnitude of additional steam leakage that would be permitted following a SGTR, and stay within licensing and design bases limits.

The inspectors determined that the licensee had not fully evaluated nor estimated current leakage for degraded components (HCV-1MS-104 and 1MS-26, Atmospheric Steam Dump Valve(s), and Steam Generator Safety Valves) since restart of Unit 1.

Furthermore, leakage estimates for degraded components that would be associated with a ruptured steam generator prior to the Unit 1 refueling/SG replacement outage were several times greater than the volumetric flow rate of 45.2 cubic feet per minute.

Stone and Webster concluded on June 27, that the allowable leakage via the available components in question, on a ruptured steam generator could be a maximum of 2.8 lbs/sec, and still be bounded by the current licensing basis.

Analysis.

The issue involved a performance deficiency in that FENOC failed to perform an adequate Operability Determination that recognized the degraded condition of the leaking valves. Had this degradation been fully recognized, the assessment would have accounted for existing leakage past the Unit 1 Residual Heat Release Valve, Atmospheric Steam Release Valve(s), and Main Steam Safety Valves, to assure off-site dose consequences were bounded in the radiological safety analysis for a SGTR event.

The inspectors evaluated this finding in accordance with IMC 0609, Appendix H, since there was the potential of increasing the Large Early Release Frequency (LERF) without affecting Core Damage Frequency (CDF), and therefore a Type B finding. Since this finding is not associated with structures, systems and components important to LERF, this finding is considered to be of very low safety significance, Green.

A contributing cause to this finding is related to the corrective action program component of the PI&R cross-cutting area, in that degraded components were not adequately evaluated to assure proper operability.

Enforcement.

10 CFR 50, Appendix B, Criterion 16, Corrective Action, requires in part, that measures shall be established to assure that conditions adverse to quality such as failures, deficiencies, defective material and equipment, and nonconformances are promptly identified and corrected.

Contrary to the above, degraded conditions (valve leakage) identified for valves HCV-1MS-104 and 1MS-26 in CRs 06-03664 and 06-03726 were not quantified or evaluated for leakage impact (additional radionuclide release) above the leakage already assumed in the radiological safety analysis of record. In addition, current leakage past Atmospheric Steam Release Valve(s), and Main Steam Safety Valves had not been quantified and evaluated for leakage impact (additional radionuclide release)above that already assumed in the radiological safety analysis of record.

Because this violation was of very low safety significance and FENOC entered this violation into their corrective action program, the violation is being treated as a Non-Cited Violation (NCV), consistent with Section VI.A.1 of the NRC enforcement policy.

.1 Beaver Valley Unit 1 Replacement Reactor Vessel Closure Head

a. Inspection Scope

The inspectors reviewed the Beaver Valley Unit 1 Replacement Reactor Vessel Closure Head (RRVCH) using the guidance in NRC Inspection Procedure 71007, Reactor Vessel Head Replacement Inspection.

FENOC elected to replace the Beaver Valley Unit 1 RVCH during the 1R17 Spring 2006 refueling outage due to demonstrated susceptibility of Alloy 600 control rod drive mechanism (CRDM) nozzles and UNS W86182 weld filler material in the existing RVCH due to primary water stress corrosion cracking. The design of the RRVCH is similar to the old RVCH except for the replacement of the Alloy 600 nozzle material and weld material with a new and improved Primary Water Stress Corrosion Cracking (PWSCC)resistant material (Alloy 690).

The RRVCH was manufactured by Equipos Nucleares, S.A. (ENSA) in Maliano, Spain.

The RRVCH was made from a one-piece hemispherical forging meeting the material requirements of ASME Code Section II, Part A, SA-508, Class 3. The RRVCH includes 48 CRDM Alloy 690 penetration pressure housing assemblies that were shrunk fit into the RRVCH and attached with alloy 152/52 filler material partial penetration welds, 8 spare control rod drive mechanism housings with threaded flanges with capped head adapters, 56 thermal sleeves, 56 guide funnels for the thermal sleeves, four instrumentation port head adapters with threaded flanges, and four instrumentation port housing guide funnels. In addition, the nozzles for the Reactor Vessel Head Vent System (RVHVS) nozzle and Reactor Vessel Level Instrumentation System (RVLIS) are attached to the RRVCH and are also constructed from Alloy 690 material.

Replacement CRDMs for the RRVCH were manufactured by Curtiss-Wright Electro-Mechanical Corporation (EMD). In addition, a new simplified head assembly (SHA) was designed for the RRVCH and manufactured by the Penn State Tool & Die Corporation.

Design and Planning The inspectors verified that the RRVCH-related design changes and modifications to components described in the UFSAR were reviewed and documented in accordance with 10 CFR 50.59. The inspectors also reviewed the adequacy of 10 CFR 50.59 applicability reviews, screening evaluations, and safety evaluations for the design changes, modifications, and procedure changes.

The inspectors reviewed applicable design documents related to the components being replaced. The inspectors compared these changes to the original reactor vessel (RV)that was designed in accordance with Westinghouse General Equipment Specification 676413, General Reactor Vessel, with Addendum Equipment Specification 678801, Beaver Valley Unit No. 1 Reactor Vessel, and the American Society Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code,Section III, 1968 Edition, through the Winter 1968 Addenda per Westinghouse Specification requirements and the new components designed in accordance with FENOC Specification 8700-CGS-0035, Westinghouse Equipment Specification 676413, and the American Society Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code,Section III, 1989 Edition.

The inspectors conducted in-office and onsite reviews of engineering change packages, engineering calculations, analyses, design specifications, material specifications, piping specifications, component specifications, installation specifications, certified design reports, and drawings for the Beaver Valley Unit 1 RRVCH, SHA, and CRDMs, to assess the technical adequacy of the design changes and to verify that the design bases, licensing bases, and the performance capability of the modified components were not degraded through the modifications.

The design and fabrication of the RRVCH, SHA and CRDMs were specified by FENOC in certified procurement specifications. Westinghouse performed the analyses, calculations or evaluations necessary to support the 10 CFR 50.59 evaluations of the RRVCH, SHA, and CRDMs. The inspectors reviewed the RRVCH design in ECP 03-0541-01, Replacement Reactor Vessel Closure Head, SHA design in ECP 03-0295-01, Simplified Reactor Vessel Head Assembly-CRDM and CETNA Head Port Adapter Section, and CRDM design in ECP 04-0432-01, Replacement Control Rod Drive Mechanisms. The engineering change packages for the RRVCH, SHA, and CRDMs include:

  • Evaluations and/or analyses to show that all applicable acceptance criteria are met with the RRVCH, SHA, and CRDMs.
  • Reviews of the plant Technical Specifications, UFSAR, SERs, and emergency operating procedures to identify changes that could be required by use of the RRVCH, SHA, and CRDMs.

The inspectors also reviewed the original design drawings of the Beaver Valley Unit 1 reactor vessel and reactor vessel head. Based on the drawings and dimensional data collected from the original components, the information was reconciled to the replacement components design dimensions and as-built drawings were developed by ENSA. The inspectors verified that the RRVCH conformed to as-built design drawings and there were no fabrication deviations from design.

Lifting/Rigging and Transportation RRVCH The adequacy of the lifting and rigging equipment associated with Beaver Valley Unit 1 RRVCH were tested and/or evaluated to verify that the maximum anticipated loads to be lifted would not exceed the capacity of the lifting/rigging equipment and supporting structures.

The inspectors reviewed the procedures for heavy lifting, inspection and testing of the cranes and lifting equipment. The inspectors verified that the capability of the lifting equipment had been inspected, tested, and/or evaluated through engineering calculations and analyses. The review focused on applicable lifting and handling procedures FENOC 1/2-ADM-0819, Handling of NUREG 012 Heavy Loads, including Bechtels work plan and inspection records (WPIR) C-RCR-147, Handling RVCHs Outside Containment and C-RCR-148, Rigging and Handling Of The RVCHs Inside Containment.

The inspectors reviewed the potential impact of load handling activities on the reactor core, spent fuel cooling, and other plant support systems, and the consequence of any impact loading of structures, systems, and components due to a RVCH drop accident.

The inspectors reviewed the Beaver Valley Unit 1 polar crane used to handle the RVCH and determined that the polar crane is not single failure proof, does not have both mechanical and electrical stops, and there is no load drop analysis as described in recommendations of phase 2 of NUREG-0612, Control of Heavy Loads at Nuclear Power Plants. The NRC provided relief in committing to phase 2 of NUREG-0612 in GL 85-11, which stated there is enough defense in depth in phase 1 in which phase 2 is not required, but recommended. The inspector verified FENOCs commitments to Phase 1 of NUREG-0612, which included all of the phase 1 guideline requirements in place regarding good practices for crane operations and load movements. The inspectors verified that the guidelines were properly implemented by reviewing the following: heavy load safe load path drawings for lifts inside Beaver Valley Unit 1 Containment, procedures for load handling operations, training and certification records of crane operators, special lifting devices, and FENOCs periodic preventive mechanical and electrical maintenance, inspections, and tests.

Removal and Replacement RVCHs The inspectors verified the temporary modification needed for containment access to support the RRVCH and steam generator replacement activity. The structural modifications and restoration of the temporary construction opening in the Beaver Valley Unit 1 containment were inspected and documented under the steam generator replacement inspection activity.

The inspectors reviewed activities associated with removal and replacement of the RVCHs. The inspectors reviewed portions of the preparation, including direct field observation of load testing of the outside lift system used to move the RVCHs and steam generators into and out of containment. The inspectors also observed portions of the lifting, rigging, down-ending, and transporting of the RVCHs into and out of containment.

Fabrication Inspections The inspectors performed direct field observations of the assembly and life cycle testing of the CRDMs at the Curtiss-Wright Electro-Mechanical Corporation (EMD) facility in Cheswick, Pennsylvania. The inspectors also conducted field observations of in-process automated canopy seal welding of CRDM latch housings-to-head adapter flanges, and reviewed liquid penetrant examination sheets of canopy seal welds 900312-02, FW-02, through 900312-13, FW-13. No relevant indications were identified in any of the canopy seal welds.

The inspectors performed reviews of FENOC Specification 8700-DGS-0035 and Westinghouse Equipment Specification 676413 for the Beaver Valley Unit 1 RRVCH, to verify that the specified material, design, fabrication, inspection, examination, testing, certification, documentation, and functional requirements were consistent with the requirements of the American Society Mechanical Engineers (ASME) Boiler and Pressure Vessel (B&PV) Code,Section III, 1989 Edition.

The inspectors reviewed the manufacturing data package reports for the Beaver Valley Unit 1 RRVCH. The data packages contained ASME Code Data Report Form -2, certified material test reports (CMTR), hydro test report, hydro test certificate, certificate of compliance, heat treatment records, post-weld stress relief heat treatment records, weld records, quality control receipt inspections, non-conformance reports, corrective actions, non-destructive examinations, and weld material acceptance tests for the manufacture of the Beaver Valley Unit 1 RRVCH. In addition, the inspectors reviewed the manufacturing reports for the CRDMs and SHA under purchase orders 55101746 and 55101403. The inspectors verified that the authorized nuclear inspector (ANI)inspected the replacement parts, reviewed the manufacturing reports, and certified that the components were fabricated and tested in accordance with ASME Code,Section III, Division 1.

Pre-Service Inspection (PSI) and Baseline Inspections The baseline examinations that provide the data for future in-service inspections and dissimilar metal examinations for CRDM, vent line, reactor vessel level instrumentation system (RVLIS) line, and serve as a pre-service inspection (PSI) in accordance with ASME Section XI requirements for dissimilar metal welds, as well as the First Revision to NRC Order EA-03-009, consists of:

(1) automated inside diameter UT and eddy current (ET) examination of 48 CRDM penetrations, RVLIS line penetration, and reactor head vent line penetration;
(2) outside diameter and J-groove weld eddy current (ECT)examination of 48 CRDM penetrations, RVLIS penetration and the vent line penetration;
(3) under head visual test (VT) examination of all J-groove welds and penetration outside diameters;
(4) top of head bare metal VT examination of all penetrations; and
(5) under head PT examination of all penetration to head J-groove welds using PT White acceptance criteria.

An inspection was conducted on-site to evaluate the licensees baseline examination of the Beaver Valley Unit 1 RRVCH. The inspectors reviewed results from the examination of the reactor vessel head penetration nozzles and the J-groove welds, and assessed the effectiveness of the NDE procedures and welding procedures.

The inspectors visually inspected Beaver Valley Unit 1 RRVCH and its penetrations. No abnormalities were observed. The inspectors observed the licensees contracted NDE personnel performing eddy current testing (ECT) examinations of the wetted surface area of the reactor vessel head penetration nozzles and J-groove welds. At the time of the inspection, ultrasonic testing (UT) data acquisition had already been completed, and UT data analysis was ongoing. The UT and ECT examinations were performed as a baseline inspection using the NRC Order EA-03-009 requirements.

The inspectors also reviewed the NDE examination results including UT and ECT of the reactor vessel head penetration nozzles and the J-groove welds. The UT analysis showed a total of five weld volumetric indications (WVIs) and 14 weld interface indications (WIIs). The licensees analysts, including a UT Level III analyst, reviewed the data and concluded that the indications were neither reportable nor recordable in accordance with their NDE procedures. However, the data was collected and stored as a baseline for future ISI inspection reference. ECT result analysis also showed no recordable indications.

The inspectors review of selected documentation, including the UT and ECT procedures, and UT and ECT data sheets of the Beaver Valley Unit 1 replacement head penetration nozzles and the J-groove welds was conducted to ensure that NDE examinations were performed according to qualified procedures. The inspectors also reviewed the automatic welding procedure related to welding of the reactor vessel head penetrations during the original fabrication.

Post-Installation Verification and Testing The inspectors verified that the post-maintenance testing (PMT) of the installed component replacements RVCH, CRDMs, and SHA cooling system and rod control system were conducted in accordance with approved procedures and verified the functional testing confirmed the design and established baseline measurements.

Specifically, procedures 3BVT-11.60.11, CRDM Cooling System Air Flow Test, 1-BVT-1.1.9, Rod Control Timing Verification Test, 1-BVT-1.1.1, Rod Drop Time Test at Hot Standby, 1OST-6.9, RCS Vent System Test, and 1MSP-6.80-1, RVLIS Train A and B Sensor Calibration were reviewed to verify the testing acceptance criteria was met.

The inspectors also reviewed results of completed procedure 1OST-6.1, Primary Side In-service Leak Test to verify that no reactor coolant system (RCS) leakage was observed from the RRVCH, RCS vent, and RVLIS piping and components during the Containment walkdowns conducted at Mode 3 normal operating pressure and temperature (NOP/NOT) by certified VT-2 Level 2 examiners.

b. Findings

No findings of significance were identified.

.2 Reactor Vessel Head Replacement Inspection

a. Inspection Scope

During the period April 3 - 7, the inspector verified that the reactor vessel head removal activities maintained adequate nuclear and radiological safety by reviewing radiation protection program controls, planning, and preparation in specific areas using applicable portions of inspection procedures 71121.01 and 71121.02. Activities related to the removal, transport, and storage of the old Reactor Vessel Closure Head were evaluated with respect to ALARA planning, dose estimates/dose tracking, exposure controls including use of temporary shielding, contamination controls, radioactive materials management, emergency contingencies, and project staffing/training. Details of this inspection are contained in Section 4OS1 and 4OS2 of this report.

b. Findings

No findings of significance were identified.

.3 Steam Generator Replacement Inspection

a. Inspection Scope

During the period April 3 - 7, the inspector verified that steam generator removal and replacement activities maintained adequate nuclear and radiological safety by reviewing radiation protection program controls, planning, and preparation in specific areas using applicable portions of inspection procedures 71121.01 and 71121.02. Activities related to the removal, transport, and storage of the old steam generators were evaluated with respect to ALARA planning, dose estimates/dose tracking, exposure controls including use of temporary shielding, contamination controls, radioactive materials management, emergency contingencies, and project staffing/training.

Details of this inspection are contained in Section 4OS1 and 4OS2 of this report.

b. Findings

No findings of significance were identified.

.4 (Closed) URI 05000412/2004-002-01, Potential for Spurious Opening of PORVs Due to

Fire Induced Hot Shorts The potential for spurious opening of the PORVs due to fire induced cable failures was identified by the licensee and documented in condition report 03-08460. The unresolved item was opened pending the results of an industry initiative to perform additional testing and evaluations of the effects of fires on cables and the likelihood of resultant fire induced faults. Independent of the industry initiative, FENOC assumed the postulated failures would occur and performed additional engineering calculations to evaluate the effects of a spurious PORV opening. The results of the analysis showed that the ability to safely shut down following a fire would not be adversely affected by a spurious PORV opening. The safe shutdown analysis was revised to reflect the results of the calculations. The failure to identify and address the spurious opening of the PORVs was the result of inadequate circuit analysis during the initial fire safe shutdown program development. As such, this issue is considered to be a violation of license condition 2.F which requires that the licensee implement and maintain in effect all provisions of the approved fire protection program as described in the Final Safety Analysis Report.

However, this issue was determined to be a minor violation because when analyzed the issue was shown to not adversely impact the safe shutdown capability. Based on review of the supporting engineering analysis and corrective actions (section 4.OA2) this item is closed.

.5 Implementation of Temporary Instruction (TI) 2515/165 - Operational Readiness of

Offsite Power and Impact on Plant Risk

a. Inspection Scope

The objective of TI 2515/165, Operational Readiness of Offsite Power and Impact on Plant Risk, was to gather information to support the assessment of nuclear power plant operational readiness of offsite power systems and impact on plant risk. The inspector evaluated licensee procedures against the specific offsite power, risk assessment, and system grid reliability requirements of TI 2515/165.

The information gathered while completing this TI was forwarded to the Office of Nuclear Reactor Regulation for further review and evaluation on April 3, 2006.

b. Findings

.6 To verify that engineering evaluations and design changes associated with steam

generator (SG) replacement are completed in conformance with requirements in the facility license, the applicable codes and standards, licensing commitments, and the regulations

a. Inspection Scope

The inspectors reviewed applicable Engineering Change Packages (ECPs) associated with the replacement of the steam generators. All ECPs were reviewed in accordance with the requirements of IP 71111.02, Evaluation of Changes, Tests and Experiments and IP 71111.17B, Permanent Plant Modifications.

The inspectors reviewed administrative procedures that controlled the screening, preparation, and issuance of the Safety Evaluation (SE) to ensure that the procedures adequately covered the requirements of 10 CFR 50.59.

The inspectors reviewed applicable procedures, work practices, and documentation of the steam generator replacement project (SGRP), and assessed the control of safety-related activities associated with the major phases of the SGRP. These activities included restoration of the pressure boundaries of the reactor coolant system (RCS),secondary systems, and containment systems, exclusion of foreign materials, and plant modifications that could affect plant risk during the replacement activities or subsequent plant operation.

The inspectors reviewed procedures that governed the cutting and machining of weld preparations at existing main steam (MS), feedwater (FW) and reactor coolant system (RCS) connections on the old steam generators (OSG). The inspectors examined welding procedures, welder qualifications, weld filler metal selection, non-destructive test procedures, examiner qualifications, acceptance criteria and test results for compliance with the requirements of the ASME Section XI. The inspectors examined training and qualification records of selected personnel performing welding and non-destructive examination. The inspectors reviewed a sample of Work Plan and Inspection Records (WIPIR) based on their risk significance, which covered the welding and installation of FW, MS and RCS piping, fittings and pipe supports. The work planning and control documents were also examined to ensure specified work tasks were appropriate and that provisions and hold points to check and close out the activities at the completion of work were appropriate.

Specific work activities inspected included observation of the qualification of welders using the cadweld process for the welding of re-bar to close the equipment opening cut in the containment building. The inspectors observed joint preparation, sleeve installation, firing, removal, cleaning and testing of a sample of the qualification welds.

Also, the inspectors observed the machining of weld end preparations on selected samples of MS, FW and RCS piping spools and assessed the dimensional accuracy for comparison with specification requirements. The inspectors observed the shop welding of various piping spools in the pipe fabrication shop prior to their movement to the field for installation. The inspectors observed the field fit-up, tack welding and final welding of a sample of these components to their respective steam generator nozzles.

One field weld from the MS, FW and RCS piping was selected by the inspectors for an in-depth inspection, beginning with the severance at the generator nozzle to the re-attachment to the steam generator, including in-process and final non-destructive testing of the new welds. The final non-destructive tests for the acceptance of these risk significant welds involved surface, radiographics and ultrasonic testing. The inspectors reviewed the test activities and inspection reports to assess the completeness of the examination processes. Also, the inspectors conducted interviews with engineers, construction, and examination personnel responsible for implementing these activities.

In addition to field activities, the inspectors reviewed the non-destructive test results of the pre-service examinations of the replacement steam generator (RSG) shell, nozzle and attachment welds, and the baseline examination of the generator tubes. The inspectors also reviewed the SG Degradation Assessment developed in advance of the pre-service tube inspections (PSI) to be performed with respect to the limited range of degradation mechanisms that may pertain to the as-built condition.

The inspectors reviewed the security considerations associated with vital and protected area barriers that may have been affected by the steam generator replacement activities, and conducted a review of the licensees compensatory measures. The inspectors also conducted a walkdown and review of security boundaries affected by the steam generator replacement project and conducted a review of the licensees compensatory measures.

The inspection of the containment construction opening included a review of the licensees plans, procedures, and processes to create a sufficiently large and safe access to the interior of the containment structure. This review included discussions with cognizant technical and management personnel, visual inspections of the work-in-progress, and review of applicable documents. The review of documents included the Design Basis of the containment as described in the UFSAR and Design Change Packages, which included the 10 CFR 50.59 safety evaluation for the modification, relevant design and the construction drawings developed for the opening, and the structural analysis of the containment structure. The work control package for the demolition of concrete, removal of reinforcing bars, and the plan and process for restoring the containment structural integrity after the SG/Reactor Head replacement were also reviewed. In addition, the inspectors evaluated the control of safety-related materials during demolition and restoration of structural concrete, including the reinforcing bar splicing methods and materials. The review also included the licensees application of industry codes and standards in the development of the restoration process of concrete and reinforcing bars.

The inspectors observed the restoration, welding and NDE of the containment liner, the re-welding of reinforcing bars, and the placement of the concrete to close the temporary construction opening. The inspectors monitored the sampling, testing, and curing of the concrete to verify that adequate strength was achieved prior to containment Type A certification test. Additionally, the inspectors reviewed a sampling of the licensees test reports from the IWE inspections performed on the interior of the containment and outside of the construction opening.
