POINT BEACH NUCLEAR PLANT NRC INTEGRATED INSPECTION REPORT 50-266/02-06; 50-301/02-06
Dear Mr. Warner:
On June 30, 2002, the U. S. Nuclear Regulatory Commission (NRC) completed an inspection at your Point Beach Nuclear Plant. The enclosed report documents the inspection findings which were discussed on June 24, 2002, with you and 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. Specifically, this inspection was a routine review of plant activities by the resident and regional inspectors and a review of radiation protection, security, heat sink, and inservice inspection activities by regional inspectors.
Based on the results of this inspection, the inspectors identified one finding of very low safety significance (Green) and one other issue for which the safety significance was still to be determined. The issue still to be determined pertained to the use of hot-calibrated steam generator narrow range level instruments during cold plant conditions. This issue did not present an immediate safety concern and will be considered an Unresolved Item pending further risk assessment activities. A preliminary NRC review of the risk significance of the finding determined that it was at least of very low safety significance (Green) since the ability to remove reactor decay heat during shutdown plant conditions was affected. Finally, one violation of very low safety significance (Green) was identified by your staff and is listed in Section 4OA7 of this report.
The NRC has increased security requirements at Point Beach in response to terrorist acts on September 11, 2001. Although the NRC is not aware of any specific threat against nuclear facilities, the NRC issued an Order and several threat advisories to commercial power reactors to strengthen licensees capabilities and readiness to respond to a potential attack. The NRC continues to monitor overall security controls and will issue temporary instructions in the near future to verify by inspection the licensee's compliance with the Order and current security regulations. In accordance with 10 CFR 2.790 of the NRCs "Rules of Practice," a copy of this letter, its enclosure, and your response, if you provide one, will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records System (PARS) component of NRCs 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 IR 05000266-02-06, IR 05000301-02-06; Nuclear Management Company, LLC; on April 1 - June 30, 2002; Point Beach Nuclear Plant, Units 1 & 2. Operability Evaluations, Refueling and Outage Activities, Surveillance Testing.
This report covers a 13-week period and was conducted by resident and regional projects, radiation specialist, security, reactor, and operator licensing inspectors. The inspectors identified one finding of at least very low safety significance (Green) that, pending further regulatory review, was considered an Unresolved Item. The inspectors also identified another finding of very low safety significance (Green) concerning the use a dedicated operator to restore a mitigating systems to service. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter 0609, Significance Determination Process. Findings for which the Significance Determination Process (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, and can be found at the Reactor Oversight Process website at http://www.nrc.gov/NRR/OVERSIGHT/assess/index.html.
A. Inspector-Identified Findings Cornerstone: Mitigating Systems
- To Be Determined. Unit 2. On April 26, 2002, during the Unit 2 U2R25 refueling outage, the inspectors identified that the steam generator narrow range level detectors, calibrated for normal, hot steam generator operating conditions were being used during cold plant conditions to satisfy Technical Specification surveillance requirements. This resulted in a non-conservative density error affecting narrow range level indication such that at steam generator temperatures of 200 degrees Fahrenheit (EF), the actual water level was approximately 4.0 percent lower (closer to the top of the U-tube bundle) than indicated. During certain accidents, this error could result in uncovering the secondary side of the top of the steam generator U-tubes. This issue did not present an immediate safety concern and was considered an Unresolved Item pending further regulatory review of the risk aspects of the density compensation error.
The inspectors concluded that the failure to account for the impact of varying water density differences on the steam generator narrow range level detector when transitioning from hot to cold plant conditions was more than minor and affected the capability of the steam generators, a mitigating system for a shutdown unit, to remove reactor decay heat. (Sections 1R20.1 and 4OA2.1).
- Green. The inspectors identified a finding of very low safety significance as a result of the licensee providing procedural guidance to a dedicated operator to perform ancillary duties away from the designated duty station, such that the intended functions could not be performed within the bounding time limits of the design basis analysis.
The inspectors determined that the issue was of more than minor significance since the issue affected the availability and capability of the G-03 emergency diesel generator, a mitigating system component, to respond to Unit 1 design basis events. Since the inspectors intervened and the dedicated operator did not perform ancillary duties away from the intended duty station such that the intended functions could not have been performed, the issue was determined not to represent a violation of NRC requirements. (Section 1R22.1)
B. Licensee-Identified Findings Violations of very low safety significance which were identified by the licensee have been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. These violations and corrective action tracking numbers are listed in Section 4OA7 of this report.

Report Details Summary of Plant Status Unit 1 began the inspection period at full power and remained there until May 4, 2002, when power was reduced to 90 percent to support switchyard maintenance activities. Unit 1 returned to full power later the same day and remained there until May 30, when power was again reduced to 90 percent to support switchyard maintenance activities. Unit 1 returned to full power operations later the same day and remained there until June 15, when reactor power was reduced to 65 percent for turbine stop valve, atmospheric steam dump, condenser steam dump, crossover steam dump, and switchyard maintenance activities. Following crossover steam dump repairs, Unit 1 returned to full power operations on June 17 and remained there through the end of the inspection period.
Unit 2 began the inspection period at full power and remained there until April 11, 2002, when power was reduced to 99.6 percent due to a plant process computer system malfunction.
Unit 2 was returned to full power operation later the same day and remained there until April 12, when the Unit was shutdown for the Unit 2 refueling outage (U2R25). The Unit 2 reactor was made critical on May 13 and synchronized to the electrical grid on May 14, 2002. Unit 2 returned to full power operations on May 17 and remained there until May 22, when reactor power was reduced to 94 percent for condenser steam dump testing. Unit 2 returned to full power operation later the same day and remained there until June 24, when power was reduced to 99.6 percent due to unreliable feedwater flow inputs to the reactor thermal power output calculation. Unit 2 resumed full power operations on June 28 and remained there through the end of the inspection period.
1. REACTOR SAFETY Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity 1R01 Adverse Weather Protection (71111.01)
.1 High Wind/Tornado Preparations a. Inspection Scope During the week of May 20, 2002, the inspectors reviewed the facility design and the licensees procedures to evaluate the facilitys susceptibility to high winds and tornado weather conditions. Additionally, the inspectors walked down selected areas to evaluate plant buildings and equipment susceptible to high winds and tornados. The inspectors also reviewed Abnormal Operating Procedure, "Severe Weather Conditions," dated July 23, 2001, which prescribed station actions for severe weather conditions.
b. Findings No findings of significance were identified.
.2 Hot Weather Preparations a. Inspection Scope During the week of May 20, 2002, the inspectors reviewed the facility design and the licensees procedures to evaluate preparations for summertime high temperatures.
Additionally, the inspectors walked down selected areas to evaluate plant equipment susceptible to high temperatures. The inspectors also evaluated the licensees scheduling of the calibration of temperature switches for the G-01 emergency diesel generator (EDG) room ventilation fans. Calibration of the switches required that the fans be out-of-service, and if the outdoor temperature exceeded 80EF with the fans inoperable, then G-01 EDG would have to be declared out-of-service.
b. Findings No findings of significance were identified.
1R04 Equipment Alignment (71111.04)
.1 Instrument Air System Partial Walkdown a. Inspection Scope During the week of May 20, 2002, the inspectors performed a partial walkdown of the Units 1 and 2 instrument air system to verify proper system configuration. The inspectors used a licensee checklist (CL), piping and instrument diagrams, and system operating procedures during the walkdown to verify that the system was properly configured for full power operations.
b. Findings No findings of significance were identified.
.2 Unit 2 Containment Spray System Partial Walkdown a. Inspection Scope During the week of May 20, 2002, the inspectors performed a partial system walkdown of the Unit 2 containment spray system to verify proper system configuration. The inspectors used licensee check lists CL 7A, Safety Injection System Checklist Unit 2, and 2-TS-ECCS-001, Safeguard Systems Valve and Lock Checklist (Monthly) Unit 2, during the walkdowns to verify that the system was properly configured. The inspectors also examined motor-operated valve and manually-operated valve material conditions to verify that the system was capable of performing design basis functions. The inspectors interviewed the system engineering staff concerning one valve with evidence of boric acid leaks. The inspectors also performed walkdowns in the control room to verify appropriate switch positions and valve configurations. Finally, the inspectors evaluated other elements such as material condition, housekeeping, and component labeling.
b. Findings
No findings of significance were identified.
.3 Service Water (SW) System Partial Walkdown a. Inspection Scope During the week of June 8, 2002, the inspectors performed a partial system walkdown of common portions of the SW system to verify proper system configuration. The inspectors used licensee CL 10B, Service Water Safeguards Lineup, Revision 52, during the walkdown to verify that the system was properly configured. The inspectors performed walkdowns in the primary auxiliary building, the EDG rooms, and the auxiliary feedwater (AFW) pump rooms to verify that switch, breaker, and valve configurations were correct and piping material condition was acceptable. During the walkdown, the inspectors also examined motor-operated and manually-operated valve material conditions to verify that the system was capable of performing design basis functions.
Finally, the inspectors evaluated other elements such as material condition, housekeeping, and component labeling.
b. Findings No findings of significance were identified.
1R05 Fire Protection (71111.05)
a. Inspection Scope The inspectors walked down the following areas to assess the overall readiness of fire protection equipment and barriers:
- Fire Zone 151, Safety Injection (SI) Pump Room
- Fire Zone 142, Component Cooling Water (CCW) Pump Room
- Fire Zone 552, SW Pump Room
- Fire Zone 582, Oil Storage Room
- Fire Zone 272, Heating, Ventilation, and Air Conditioning Fan Room - Unit 1
- Fire Zone 273, Heating, Ventilation, and Air Conditioning Fan Room - Unit 2
- Fire Area A01E, Unit 2 Turbine Building Operating Floor
- Fire Area 104, Unit 1 1P-10A Residual Heat Removal (RHR) Pump Room
- Fire Area 105, Unit 1 1P-10B RHR Pump Room Emphasis was placed on the control of transient combustibles and ignition sources, the material condition of fire protection equipment, and the material condition and operational status of fire barriers used to prevent fire damage or propagation. Area conditions/configurations were evaluated based on information provided in the licensees Fire Hazards Analysis Report, August 2001.
The inspectors toured the fire zones to verify that fire hoses, sprinklers, portable fire extinguishers, and fire detectors were installed at their designated locations, were in satisfactory physical condition, and were unobstructed. Additionally, passive features such as fire doors, fire dampers, and mechanical and electrical penetration seals were
examined to verify that they were located per Fire Hazards Analysis Report requirements and were in good physical condition.
b. Findings No findings of significance were identified.
1R06 Flood Protection Measures (71111.06)
.1 Annual Review of Internal and External Flood Protection Measures a. Inspection Scope During the week of May 13, 2002, the inspectors reviewed internal and external flooding design bases documents, flooding mitigation equipment, and risk analyses to determine if existing configurations and mitigation plans were consistent with design requirements and risk analysis assumptions. The inspectors walked down the following areas to assess the overall readiness of flood protection equipment and barriers.
- Heating, Ventilation, and Air Conditioning Equipment Room (above the control room)
- Auxiliary Building (focusing on the containment building facade area and portions of the RHR pump room flood barrier configuration)
- EDG Rooms (G-01 and G-02)
- Instrument Air Compressor Room
- Turbine Building (auxiliary building secured access doors)
- AFW Pump Rooms
- Circulating Water Pump House Wave Barrier Locations
- Vital Switchgear and Battery Rooms Emphasis was placed on the material condition of flood protection equipment, and the material condition and operational status of flood barriers used to mitigate flood damage or propagation. Flood protection features such as flood doors and door gaps, subsoil drains, and flood zone penetration seals were also inspected to verify that they were in satisfactory physical condition, unobstructed, and capable of providing an adequate flood barrier. Inspectors reviewed the licensees normal and abnormal operating procedures, associated with flood identification and mitigation. Also, the inspectors reviewed annunciator response procedures associated with high sump level alarms and the associated lack of equipment calibration.
The inspectors reviewed several corrective action program documents, including an action request (AR) identified during the inspectors plant walkdowns. Specifically, AR 3333, Various Flooding Issues, concerning broken subsoil drain straps and flood door material condition deficiencies was reviewed. In addition, several other licensee-identified condition reports (CRs), still in open status, were also reviewed to determine the adequacy of the implemented and pending corrective actions.
b. Findings
No findings of significance were identified.
1R07 Heat Sink Performance (71111.07)
.1 Biennial Review of Heat Sink Performance a. Inspection Scope The inspector reviewed documents associated with testing, inspection, cleaning and performance trending of heat exchangers, primarily focusing on the Component Cooling Heat Exchanger HX-12A and the Unit 1 Residual Heat Removal Heat Exchanger PB1 HX-11A. These two heat exchangers were chosen based on their importance in supporting required safety functions as well as relatively high risk achievement worths in the plant specific risk assessment. Component Cooling Heat Exchanger HX-12A was also selected to evaluate the licensees thermal performance testing methods. Waste Gas Heat Exchanger HX-48A-1 was originally included in the scope of this inspection based on a relatively high risk achievement worth; however, the licensee reassessed the risk achievement worth of the heat exchanger as relatively low so it was removed from the scope of the inspection. The inspector reviewed completed surveillance tests and associated calculations, and performed independent calculations to verify that these activities adequately ensured proper heat transfer. The inspector reviewed the documentation to confirm that the test or inspection methodology was consistent with accepted industry and scientific practices, based on review of heat transfer texts and Electrical Power Research Institute standards (EPRI NP-7552, Heat Exchanger Performance Monitoring Guidelines, December 1991; EPRI TR-107397, Service Water Heat Exchanger Testing Guidelines, March 1998).
The inspector reviewed condition reports concerning heat exchanger and ultimate heat sink performance issues to verify that the licensee had an appropriate threshold for identifying issues and entering them in the corrective action program. The inspector also evaluated the effectiveness of the corrective actions for identified issues, including the engineering justification for operability, if applicable.
The documents that were reviewed are listed at the end of the report. Also attached are the two information requests sent to the licensee in preparation for the inspection of this area: (1) the request for the inspection originally scheduled December 3-7, 2001, but postponed; and (2) the revised request for the inspection accomplished on June 10-14, 2002.
b. Findings No findings of significance were identified.
1R08 Inservice Inspection (ISI) Activities (71111.08)
a. Inspection Scope The inspectors evaluated the implementation of the licensees ISI program for monitoring degradation of the reactor coolant system (RCS) boundary and the risk significant piping system boundaries. Specifically, the inspectors observed in-process liquid penetrant inspections of pressurizer pipe-to-reducer weld (CVC-02-AS-2001-29),
swage reducer-to-valve weld (RC-03-PSF-2003-08A), pipe-to-swage reducer weld (RC-03-PSF-2003-08A), and magnetic particle inspection of feedwater pipe-to-nozzle weld (FW-16-FW-2002-18G) to verify that they were conducted in accordance with the American Society of Mechanical Engineers Boiler and Pressure Vessel Code requirements.
The inspectors also reviewed ISI procedures and personnel and equipment certifications. The inspectors reviewed the NIS-2 forms for code repairs performed during the last Unit 2 outage (U2R24) to confirm that code requirements were met. In addition, the inspectors reviewed CRs concerning ISI issues to verify that an appropriate threshold for identifying issues had been established. The inspectors also evaluated the effectiveness of the corrective actions for identified issues. In addition, the inspectors reviewed the licensees operating experience review process to verify that operating experience was correctly assessed for applicability by the ISI group.
b. Findings No findings of significance were identified.
1R11 Licensed Operator Requalification (71111.11)
.1 Resident Inspector Quarterly Review: Instrument Failure With Steam Release from Both Steam Generators a. Inspection Scope On May 23, 2002, the resident inspectors observed licensed operator training involving a steam leak on an 'A' steam generator sensing line followed by a reactor trip and depressurization of the 'B' steam generator due to a stuck open safety valve. The scenario focused on communications standards, peer checking, and peer-to-peer feedback. The inspectors evaluated crew performance for clarity and formality of communication; the ability to take timely action in the safe direction; the prioritizing, interpreting, and verifying of alarms; the correct use and implementation of procedures, including alarm response procedures; timely control board operation and manipulation, including high-risk operator actions; and group dynamics. The inspectors observed the post-scenario crew critique and reviewed the instructor's written observations to verify that areas for improvement had been identified and entered into performance development initiatives.
b. Findings No findings of significance were identified.
1R12 Maintenance Rule Implementation (71111.12)
a. Inspection Scope The inspectors reviewed the implementation of the maintenance rule to verify that component and equipment failures were identified, entered, and scoped within the maintenance rule and that selected systems, structures, and components were properly categorized and classified as (a)(1) or (a)(2) in accordance with 10 CFR 50.65. The inspectors reviewed station logs, maintenance work orders (WOs), CRs, ARs, (a)(1)
corrective action plans, selected surveillance test procedures, and a sample of CRs to verify that the licensee was identifying issues related to the maintenance rule at an appropriate threshold and that corrective actions were appropriate. Additionally, the inspectors reviewed the licensees performance criteria to verify that the criteria adequately monitored equipment performance and to verify that licensee changes to performance criteria were reflected in the licensees probabilistic risk assessment.
Specific components and systems reviewed were:
- Cable Spreading Room Heating and Ventilation System during the week of April 8, 2002
- 125-Volt Direct Current Electrical System during the week of May 6, 2002 b. Findings No findings of significance were identified.
1R13 Maintenance Risk Assessment and Emergent Work Evaluation (71111.13)
a. Inspection Scope The inspectors reviewed the licensees evaluation of plant risk, scheduling, configuration control, and performance of maintenance associated with planned and emergent work activities, to verify that scheduled and emergent work activities were adequately managed. In particular, the inspectors reviewed the licensees program for conducting maintenance risk safety assessments to verify that the licensees planning, risk management tools, and the assessment and management of on-line risk were adequate. The inspectors also reviewed licensee actions to address increased on-line risk when equipment was out-of-service for maintenance, such as establishing compensatory actions, minimizing the duration of the activity, obtaining appropriate management approval, and informing appropriate plant staff, to verify that the actions were accomplished when on-line risk was increased due to maintenance on risk-significant systems, structures, and components. The following specific activities were reviewed:
- The maintenance risk assessment for work planned for the week beginning May 12, 2002. This work included overhaul and surveillance testing of the
P-32E SW pump with the G-02 EDG out-of-service and transition of Unit 2 from the deterministic shutdown safety assessment (SSA) model to the quantitative on-line risk monitor during plant heat-up and startup activities.
- The maintenance risk assessment for work planned for the week beginning May 19, 2002. This work included risk-significant surveillance testing of the G-01 EDG, drilling into the basemat and subsequent testing to address a vibration problem associated with the generator-end of the G-02 EDG, and inspection and maintenance of the south SW header strainer.
- The maintenance risk assessment for work planned for the week beginning June 17, 2002. This work included calibration of the temperature switch for the G-01 EDG room ventilation system, repair and testing of the electric fire pump, and repair and testing of the turbine/moisture separator reheater crossover steam dump system.
- The maintenance risk assessment for work planned for the week beginning June 24, 2002. This work included 4.16 kilovolt (kV) undervoltage surveillance tests for Units 1 and 2, SI system maintenance, and a diesel fire pump engine inspection, repair, and post-maintenance test.
b. Findings No findings of significance were identified.
1R15 Operability Evaluations (71111.15)
.1 Reduced Charging Flow During a Postulated Fire Due to Lack of a Nitrogen Backup Supply a. Inspection Scope During the week of May 20, 2002, the inspectors reviewed Engineering Evaluation 2002-016, MAAP [Modular Accident Analysis Program] Analysis to Support Reduced Charging Flow, to determine the transient behavior of the RCS in the event of an Appendix R fire scenario, assuming only 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> of single charging pump speed control was available. The issue was reported in Event Notification 38819 as an unanalyzed condition that had the ability to significantly degrade plant safety, since certain Appendix R scenarios required the availability of a single charging pump, operable at greater than minimal pump capacity, in order to meet the Appendix R performance goal of maintaining adequate RCS inventory without loss of pressurizer level indication.
The inspectors reviewed the licensee input and assumptions used in the transient analysis to verify the realism and accuracy of the analytical results. The inspectors examined the modeling of the reactor coolant pump (RCP) seal package failure during the Appendix R scenario as a series of small-diameter RCS breaks to verify that the approach remained bounding for the seal package characteristics predicted by the vendor. The inspectors compared the RCP seal package and the top-of-active fuel elevations to verify that, despite predicted voiding in the RCS, the core would remain
covered and adequate core cooling would be maintained by a combination of steaming to containment and reflux cooling in the steam generator tubes. Finally, the inspectors reviewed core water temperature analytical results during the Appendix R scenario to verify that peak cladding temperatures remained well below the limits of 10 CFR Part 50.46.
b. Findings Engineering Evaluation 2002-006 estimated the transient behavior of the RCS during a safe-shutdown Appendix R fire scenario with the normal cooling and safety systems unavailable. The evaluation included the loss of instrument air, RCP seal failures, disabling of charging pumps for the first 50 minutes of the scenario, and an initial charging capacity of 60 gallons per minute followed by a reduction to 18 gallons per minute 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> into the transient, due to loss of the back-up nitrogen supply. Reactor coolant pump seal leakage profiles provided by the seal vendor were simulated by varying the size of small break loss-of-coolant accidents as a function of RCS pressure.
The evaluation demonstrated that approximately 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> into the transient, when charging flow was reduced to 18 gallons per minute, pressurizer level and pressure would no longer be maintained. Approximately 11.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> into the transient, as RCS conditions approached those near the steam generator secondary saturation conditions, the evaluation demonstrated that RCS subcooling would be lost and voiding would begin to occur in the primary system. In addition, since the charging flow would be unable to keep up with the RCP seal break flow, RCS inventory would continue to be lost and the RCP seals would eventually begin to emit steam. Once the RCP seals were uncovered and the break flow became all steam, the charging flow would become sufficient to maintain RCS inventory near the RCP seal elevation. Venting of steam at the RCP seal elevation maintained approximately 11.0 feet of water over the top-of-active fuel in the reactor core. As RCS pressure would continue to decrease, the evaluation predicted that the reactor vessel would approach saturation conditions and bulk boiling would occur in the core. The engineering evaluation demonstrated that the water in the core would remain at approximately 570EF, provide a large margin to the peak cladding temperature limit of 10 CFR Part 50.46, and prevent core damage.
This issue was determined to be more than minor and affected the barrier integrity cornerstone objective since the lack of sufficient back-up nitrogen capacity for the charging pumps would, had a safe shutdown Appendix R fire scenario occurred, have resulted in loss of the RCP seals, an active component of the RCS boundary required for RCS functionality. The loss of the RCP seals would have led to voiding portions of the RCS primary system causing unintended boiling in the reactor core.
The inspectors used Manual Chapter 0609, Significance Determination Process, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations, regarding the mitigating systems and RCS barrier integrity and determined that:
- The finding did not result in fuel damage since back-up nitrogen supply was never required during an Appendix R safe shutdown scenario and engineering
evaluations demonstrated that fuel temperatures would have remained well below regulatory had an Appendix R analyzed fire occurred;
- The finding did not represent an actual loss of the functionality of the RCS boundary since no Appendix R safe shutdown scenario occurred and RCS barrier integrity was never challenged through the loss of the RCP seals;
- The finding was not a design or qualification deficiency;
- The finding did not result in a loss of function of a single train of any mitigating systems for greater than its Technical Specifications (TS) allowed outage time and did not represent an actual loss of the safety function for any mitigating system;
- The finding did not represent an actual loss of safety function of one or more non-TS trains of equipment designated as risk significant per 10 CFR 50.65 for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />;
- The finding did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event in that the finding did not involve the loss or degradation of equipment or function specifically designed to mitigate a seismic, flooding or severe weather initiating event; and
- The finding did not involve the degradation of a fire protection barrier or loss of a safety function that contributed to external event initiated core damage accident sequences.
Therefore, the finding screened as Green and was of very low safety significance. This issue is dispositioned in Section 4OA7 of this report.
.2 Auxiliary Building High Energy Line Break (HELB) Analysis a. Inspection Scope During the week of April 29, 2002, the inspectors reviewed Operability Determination 98-0164, Qualification of Electrical Equipment, and AR 2976, Problems with OD
[Operability Determination] 98-0164 (PAB [Primary Auxiliary Building] HELB), to determine if a CCW pump that was assumed idle when a PAB steam line break occurred, could subsequently be started with adverse conditions present in the PAB.
Since the charging pumps were not credited during a HELB in the PAB, the inspectors concentrated on the CCW pumps, since they were required to maintain the RCP seals intact and prevent progression of the event to a small break loss-of-coolant accident.
The inspectors compared the assumptions and conclusions in the operability determination against the Final Safety Analysis Report (FSAR) requirements to verify that components in the PAB would be able to meet design basis requirements. In addition, the inspectors reviewed the use of the simulator in determining plant response to a HELB to verify that plant response was accurately modeled and applied to the operability determination.
b. Findings No findings of significance were identified.
.3 Unit 2 Containment Fan Coil Unit Reduced Flow Rate
a. Inspection Scope During the week of May 20, 2002, the inspectors reviewed Operability Determination 01-1559, Unit 2 Containment Fan Coil Unit Reduced Flow Rates, to verify the containment fan coils remained capable of removing containment heat loads during design basis accidents and maintaining containment temperatures and pressures within design limits. The inspectors compared FSAR containment fan coil heat removal data against the reduced air flow characteristics in the operability determination to determine the effect on peak containment pressures. The inspectors considered the potential effects of higher peak containment pressures on the environmental qualification of structures, systems, and components inside containment, an item not addressed in the operability determination.
b. Findings No findings of significance were identified.
.4 Common Cause Failure Analysis For Aborted G-02 EDG Extended Surveillance Test a. Inspection Scope During the week of June 10, 2002, the inspectors reviewed AR 28360, G-02 Failure During the Performance of TS 82 Extended Run, and AR 28420, G-02 Run At Full KW [Kilowatt] Loading and Above Full Load KVAR [Kilovolt-Amperes Reactive] On Two Separate Occasions, to determine the common mode failure applicability to other EDGs. The inspectors compared the EDG voltage regulator circuit designs and observed licensee troubleshooting efforts to verify that common mode failure concerns did not apply to the other EDGs. The inspectors also conducted reviews to verify that surveillance testing of the G-01 EDG with a similar circuit design was performed to ensure operability of the Unit 1, 'A' train EDG. When the cause of the G-02 surveillance failure was determined to be a tripped generator field excitation breaker, the inspectors reviewed the manufacturer's circuit breaker information to understand if the breaker had operated as expected and per design. The inspectors reviewed the licensee's conclusion that the cause of the excitation breaker trip was a low-reading Volt-Amperes Reactive meter in the control room resulting in the EDG being overexcited to achieve the Kilovolt-Amperes Reactive indication required by the G-02 routine inspection test. The inspectors considered the impact of the EDG over-excitation on design basis EDG accident response to ensure that all emergency core cooling system (ECCS) equipment would still have operated as expected. Finally, the inspectors considered the over-excitation effects on increased generator heat loads and the resultant effects on winding insulation resistance and life.
b. Findings No findings of significance were identified.
.5 Relaxation of Reactor Power Limits for an Inoperable Crossover Steam Dump System a. Inspection Scope
The inspectors reviewed the licensees relaxation of previous procedural constraints on reactor power when the turbine/moisture separator reheater crossover steam dump system was inoperable. This system was one of several turbine overspeed protection systems at Point Beach and was declared inoperable on June 16 due to a problem with one of the four valves during testing on Unit 1. The basis for the licensees revised position was an analysis done several years ago by the turbine vendor that concluded that the crossover steam dump system at Point Beach was not needed for overspeed protection.
b. Findings No findings of significance were identified.
.6 Unit 1 Turbine-Driven Auxiliary Feedwater Pump Outboard Bearing Degradation a. Inspection Scope During the week of June 10 and 24, 2002, the inspectors reviewed Operability Determination OPR-000019, 1P-29 Turbine-Driven Aux Feed Pump Outboard Bearing Degradation, to verify that the pump remained capable of performing its intended safety function. The inspectors reviewed a May 2002 ferrogram oil analysis report to determine the degree of bearing wear that had occurred and to estimate the rate of wear progression since the last oil sample taken in November 2001. The inspectors considered the wear particle sizes, the dimensions of the lubrication hydrodynamic gaps, and the metallurgical components of the oil analysis to determine the degree to which the turbine journal bearing babbitt material had been affected by the wear particles found in the oil sample. The inspectors also reviewed turbine vibration and acceleration measurements to estimate whether bearing wear was in an early or advanced stage of development. Finally, the inspectors reviewed licensee plans and WOs to change and re-sample the turbine bearing oil to understand licensee actions for monitoring bearing performance.
b. Findings No findings of significance were identified.
1R16 Operator Workarounds (OWAs) (71111.16)
.1 Spurious Alarms During Start Of Safeguards Pumps a. Inspection Scope The inspectors reviewed OWA 0-00R-004 to understand potential effects on plant operations caused by operators responding to spurious alarms received during the start of Unit 1 and Unit 2 safeguards pumps. The inspectors interviewed engineering personnel, reviewed the pending modification, and examined the developed work package to evaluate the adequacy of planned licensee actions. The workaround concerned the start of large Unit 1 and Unit 2 motors affecting the 480-volt supply to the battery chargers which, in turn, caused DC bus perturbations. The inspectors
reviewed the proposed changes to determine if the incorporation of alarm circuit time delay relays would allow the DC bus to return to a normal levels following the starting a large motor and prevent spurious alarms. Finally, the inspectors reviewed diagrams to ascertain that the modification would not adversely interfere with the safety function of the DC charging system or the ground detection system.
b. Findings No findings of significance were identified.
1R19 Post-Maintenance Testing (PMT) (71111.19)
.1 Gas Turbine Generator G05 Testing a. Inspection Scope The inspectors reviewed PMT activities associated with the G-05 gas turbine generator, which had been taken out-of-service on May 21, 2002 to remove residual fuel oil from the generator battery cells. The oil had been sprayed on the battery when a relief valve lifted during previous generator operations. Although the bulk of the oil had been cleaned up after the relief valve lifted, the battery manufacturer recommended more extensive cleaning to prevent long-term degradation of the plastic battery cell cases from traces of fuel oil. After the cleanup, the licensee conducted Periodic Check 29, Monthly Gas Turbine and Auxiliary Diesel Load Test, Revision 34, for the PMT. The licensee chose to perform the more extensive monthly test, rather than just a check of battery parameters, because of previous instances where emergent equipment problems occurred after the generator had been out-of-service for an extended period of time. The inspectors reviewed WO 0205569, under which the battery cleanup work had been done, and the records associated with the completed Periodic Check (PC) 29 surveillance test, to verify that the test was adequate for the scope of the maintenance that had been performed and that the test data were complete, appropriately verified, and met the requirements of the test procedure.
b. Findings No findings of significance were identified.
.2 Replacement of 2RC-00427, Unit 2 RCS 'B' Loop Cold Leg to Chemical and Volume Control System Letdown Isolation Valve a. Inspection Scope The inspectors observed portions of freeze seal operations and the PMT associated with replacement of 2RC-427, 'B' RCS Loop Cold Leg to Chemical and Volume Control system letdown isolation valve, during the Unit 2 refueling outage to ensure the integrity of RCS pressure boundary material. Selected RCS boundary welds were inspected to verify proper fillet dimensions, lack of porosity due to moisture intrusion, and good pipe-to-pipe alignment. Since 2RC-00427 was unisolable from the reactor vessel and fuel was loaded in the core during the valve replacement, the inspectors walked down
portions of the freeze seal to verify that system pressures, ambient temperatures, fluid temperatures, pipe geometry, pipe material, pipe restraints, and pipe weld limitations were within specified parameters. The inspectors reviewed the piping classification and original construction code requirements associated with 2RC-00427 to verify that the non-destructive examinations performed as part of the PMT met applicable Code requirements. The inspectors reviewed the completed WO and final non-destructive examination records associated with the valve replacement to verify that all visual, dye penetrant, and ultrasonic examinations had been completed and recordable indications properly dispostioned.
Finally, the inspectors reviewed Corrective Action Process (CAP) 028627, Documentation Deficiencies Identified In a Completed (Reviewed) Work Order, which was initiated as a result of this inspection activity and discussed missed documentation concerning post-maintenance visual and dye penetrant testing results.
b. Findings No findings of significance were identified.
.3 Repair and Testing of the Electric Fire Pump, P-35A a. Inspection Scope The inspectors reviewed the repair and subsequent PMT of the electric fire pump, P-35A. The pump had been taken out-of-service in mid-June for replacement of the upper end bell, an oil change, replacement of its 480-volt breaker, and repacking.
b. Findings No findings of significance were identified.
.4 Repair and Testing of the Spent Fuel Pool (SFP) System a. Inspection Scope The inspectors reviewed the repair and PMT of the spent fuel system. The repairs included cleaning and eddy current testing of, and plugging of a defective tube in the HX-13A SFP heat exchanger, and replacement of the 2-inch SFP return to SFP Valve, SF-28.
b. Findings No findings of significance were identified.
.5 Diesel-Driven Fire Pump 3-Year Maintenance Overhaul a. Inspection Scope The inspectors observed portions of the overhaul activities associated with the diesel-driven fire pump, P-35B, to gain insights into the adequacy of the PMT activities.
The inspectors also reviewed design basis requirements and observed portions of the tests performed in accordance with Point Beach 0-PT-FP-002, Monthly Diesel Engine-Driven Fire Pump Functional Test, Revision 1, to verify that the fire pump was capable of performing its design functions. The inspectors reviewed the completed test documentation to verify that all acceptance criteria had been met.
b. Findings No findings of significance were identified.
.6 Unit 1 CCW Expansion Tank Level Transmitter Replacement a. Inspection Scope During the week of June 24, 2002, the inspectors observed portions of the replacement of level transmitter 1LT-618, CCW Surge Tank Level Transmitter, and reviewed WO 9949340 to verify that remote control room indication of leaks into or out of the CCW system was maintained. The inspectors performed a walkdown of the level transmitter and associated connections following the transmitter replacement to verify that the instrument had been properly returned to service, was leak tight, and remained capable of providing remote alarms to the control room. The inspectors also reviewed the use of a temporary tygon tube, monitored locally, for surge tank level measurements to verify that the proximity of the actual level to alarm setpoints had been understood by auxiliary operators.
b. Findings No findings of significance were identified.
1R20 Refueling and Outage Activities (71111.20)
.1 Use of Steam Generator Narrow Range Level Detector During Cold Shutdown a. Inspection Scope The inspectors reviewed the use of the steam generator narrow range level detector in Mode 3 (hot standby, RCS >350EF), Mode 4 (hot shutdown, RCS between 200EF and 350EF), and Mode 5 (cold shutdown, RCS <200EF) to determine if the effect of water density changes with decreasing plant temperatures had been considered in detector parametric uncertainty analyses. The inspectors interviewed selected engineering and operations personnel and performed independent calculations to determine the magnitude of the density error associated with using the hot-calibrated steam generator narrow range water level detector during cold plant conditions. The inspectors
reviewed setpoint and shutdown emergency procedure background documents to determine the intent of establishing a 29 percent steam generator narrow range level setpoint during cold plant conditions. The inspectors also reviewed operator logs and selected surveillance, inservice, and infrequently performed test evolution procedures to determine the extent to which the steam generator narrow range level detector density correction errors existed in plant procedures.
The inspectors reviewed plant specific steam generator construction drawings and combined detector readability, loop uncertainty, and density errors to determine whether, under certain plant conditions, the top of the steam generator U-tubes could become uncovered while the steam generator was being credited as an alternate means of reactor decay heat removal. The inspectors performed independent calculations to estimate the amount of U-tube heat transfer surface area lost on the secondary side of the steam generators as a result of the combined level detector errors causing the upper portions of the U-tubes to become uncovered. The inspectors reviewed engineering evaluations, temporary procedure changes, procedure feedback forms, and safety evaluation screenings to ensure the licensee had identified all the vulnerabilities associated with the steam generator narrow range level detector density compensation issue. To evaluate the effectiveness of licensee internal communications, the inspectors reviewed licensee actions following the first inspector notification of the issue on April 30, 2002, and the time before all procedure changes were identified on May 28, 2002.
b. Findings The inspectors identified an Unresolved Item of at least very low safety significance concerning the failure to account for the impact of varying water density differences on the steam generator narrow range level detector variable leg when transitioning from hot to cold plant conditions. Specifically, safety-related shutdown emergency procedures contained operator instructions that could have caused the top of the steam generator U-tubes to become uncovered, thereby affecting the ability of the steam generators to function as a heat sink for removing reactor decay heat.
Description On April 26, 2002, during the Unit 2 refueling outage (U2R25) the inspectors determined that the steam generator narrow range level detectors, calibrated for normal, hot steam generator operating conditions of 521EF and 821 pounds per square inch absolute pressure, were being used during cold plant conditions to satisfy TS surveillance requirements 3.4.5.2, 3.4.6.2, and 3.4.7.2. The inspectors observation was that as steam generator water temperatures decreased (and level detector variable leg water densities increased) during a plant shutdown and cooldown, the difference between the narrow range indicated and actual water level increased in the non-conservative direction. At 200EF, this unaccounted density error resulted in a condition where the actual water level was approximately 4.0 percent lower (closer to the top of the U-tube bundle) than indicated.
Technical Specification surveillance requirements 3.4.5.2 and 3.4.6.2 required that once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> in Modes 3 and 4 the steam generator secondary side water level be
verified greater than or equal to 30 percent narrow range for the required RCS loops being relied upon for decay heat removal. The applicable TS bases sections stated that if the water level was less than 30 percent, the U-tubes might become uncovered and the associated loop might not be able capable of providing a heat sink for removal of reactor decay heat. Similarly, TS 3.4.7.2 required that once per 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> in Mode 5 water level be verified greater than or equal to 30 percent narrow range in the required steam generator. The applicable TS bases section stated that a steam generator was operable when the secondary side narrow range water level was greater than or equal to 30 percent since this level ensured an alternate method of decay heat removal via natural circulation in the event a second RHR loop was not operable.
The inspectors reviewed steam generator construction drawings and determined that the actual top occurred at 25.1 percent narrow range for the Unit 1 Model 44F steam generator U-tube bundle and at 25.3 percent narrow range for the Unit 2 Model D47 steam generators. In addition, the inspectors reviewed licensee setpoint verification program calculations PBNP-IC-25, Steam Generator Narrow Range Level Instrument Uncertainty and Setpoint Calculation and PBNP-IC-26, Steam Generator Narrow Range Water Level Scaling Calculation, which discussed a 1 percent readability and 2.55 percent (rounded to 3 percent) total loop uncertainty error in the negative direction associated with the narrow range level instruments. The inspectors noted that these setpoint calculations had only been performed for normal operating and adverse containment conditions. Neither the calculations or the associated engineering evaluations accounted for the effects of increasing level detector variable leg water densities as steam generator water temperatures decreased during a plant shutdown and cooldown. Interviews with engineering and instrumentation and control personnel revealed that the density affect accounted for an approximate 2.2 percent non-conservative level deviation at 350 EF and an approximate 4.0 percent non-conservative level deviation at 200 EF.
To understand the bounding aspects of the density error, the inspectors considered the linear sum of the readability (1 percent), loop uncertainty (2.6 percent), and density errors (4.0 percent) that would impact the steam generator level detector in the negative direction at 200EF. Specifically, the inspectors considered the worst case, cumulative affect of the errors on two parts of safety-related Shutdown Emergency Procedure (SEP) 3.0, Loss of All AC [Alternating Current] Power to a Shutdown Unit -
Unit 1, Revision 12, and SEP 3.0, Loss of All AC Power to a Shutdown Unit - Unit 2, Revision 13. Shutdown Emergency Procedure 3.0 provided direction for a loss of all alternating current power to a shutdown unit while the SI accumulators were isolated.
In the first part of SEP 3.0, Step 5.b directed control room operators to check for at least one steam generator capable of being filled to greater than 29 percent narrow range (51 percent for adverse containment conditions). The background document for SEP 3.0, Step 5 stated that it was not necessary for the steam generator to be completely intact to consider it available as a secondary heat sink. Rather, if the U-tubes were intact and there was an available means to add water, the steam generator would remove decay heat. In the second part of SEP 3.0, Step 8.b directed control room operators to check at least one steam generator greater than 29 percent narrow range level (51 percent for adverse containment conditions). The background document for SEP 3.0, Step 8, stated that if the steam generator was to be used as a
secondary heat sink, the steam generator U-tubes must remain covered to maintain natural circulation.
The inspectors determined that the linear sum of the worst case steam generator level detector errors in the negative direction at 200EF was 7.6 percent (1 percent + 2.6 percent + 4.0 percent = 7.6 percent). Applying this error to the 29 percent narrow range level guidance provided to control room operators in SEP 3.0, Steps 5.b and 8.b meant that the actual level in the steam generators could be 21.4 percent (29 percent minus 7.6 percent = 21.4 percent). For Unit 1 with the top of the U-tubes at 25.1 percent narrow range, this meant that a portion of the top of the U-tubes equivalent to 3.7 percent (25.1 minus 21.4) of the steam generator narrow range level detector 100 percent span could be uncovered. The 3.7 percent narrow range translated into the potential to uncover 7.6 inches of the top of the Unit 1 steam generator U-tubes. Using approximations from Unit 2 steam generator vendor drawings, this resulted in the potential uncovering of at least some part of 220 of 3214 tubes or about 6.9 percent of the U-tubes in Unit 1 steam generators. The inspectors estimated that uncovering the top 7.6 inches of the U-tubes would result in a loss of approximately 1 percent of the heat transfer area associated with the affected Unit 1 steam generator.
For Unit 2 with the top of the U-tubes at 25.3 percent narrow range, summing the worst case errors meant that a portion of the top of the U-tubes equivalent to 3.9 percent (25.3 minus 21.4) of the steam generator narrow range level detector 100 percent span could be uncovered. The 3.9 percent narrow range translated into the potential to uncover 8 inches of the top of the U-tubes in the Unit 2 steam generators. Using vendor steam generator drawings, this resulted in the potential uncovering of at least some part of 247 of 3499 tubes or about 7 percent of the U-tubes in Unit 2 steam generators. The inspectors estimated that uncovering the top 8 inches of the U-tubes in a steam generator would result in a loss of approximately 1 percent of the heat transfer area associated with the affected steam generator.
The inspectors also considered the sum of the readability, loop uncertainty, and density errors using the square root of the sum of the squares (SRSS) methodology. The SRSS methodology represented a combination of statistical and algebraic methods that combined random and independent uncertainties with non-random or bias errors.
Using the SRSS methodology, the readability and loop uncertainty errors were considered random and independent variables taken to act in the negative, non-conservative direction. The density error was treated as a bias with a known sign, acting in a specific direction, and known to contribute a fixed 4 percent uncertainty in the negative direction. The result of the SRSS methodology provided a 6.7 percent combined error that did not change the effect of uncovering a portion of the top of the steam generator U-tubes.
Analysis The inspectors assessed this issue using NRC Inspection Manual Chapter 0609, Significance Determination Process, Appendix G, issued February 27, 2001. The inspectors concluded that the failure to account for the impact of varying water density differences on the steam generator narrow range level detector when transitioning from hot to cold plant conditions had a credible affect on safety since the ability of the steam
generators to remove reactor decay heat was affected. Specifically, safety-related shutdown emergency procedures contained operator instructions that could have caused the top of the steam generator U-tubes to become uncovered, thereby affecting the ability of the steam generators to function as a heat sink for removing reactor decay heat.
The inspectors reviewed licensing basis requirements and determined that prior to November 2001, TSs contained no steam generator narrow range water level requirements in Modes 3, 4, or 5 to ensure steam generator availability as a heat sink to remove reactor decay heat. Following the transition to Improved TSs at Point Beach during November 2001, however, TS surveillance requirements 3.4.5.2, 3.4.6.2, and 3.4.7.2 were added requiring that steam generator narrow range level be greater than or equal to 30 percent to verify steam generator operability as a heat sink to remove reactor decay heat. In the time period following November 2001, to the end of this report period, Unit 1 had not entered Mode 3, 4, or 5. Unit 2, however, completed a refueling outage between April 12 and May 14, 2002.
To understand the impact of the density compensation error on plant risk, the inspectors reviewed those portions of the refueling outage where the steam generators had been credited as an alternate method of reactor decay heat removal. These periods were then applied to the applicable Significance Determination Process, Phase 1, Appendix G Screening worksheet. Two periods applicable to the Phase 1 worksheets were identified.
During the first period near the beginning of the outage, from April 14 at 4:30 p.m. to April 15, 2002, at 4:45 p.m. (approximately 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />), the steam generators were credited as an alternate means of decay heat removal while Unit 2 was in Mode 5 (cold shutdown), the RCS was intact, the reactor coolant loops were full, inventory was maintained in the pressurizer, and time-to-boil in the core was less than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. The first period was a condition specifically identified in the second of four Appendix G pressurized water reactor Phase 1 screening worksheets, PWR [Pressurized Water Reactor] Cold Shutdown Operation, RCS Closed and Steam Generators Available for DHR [Decay Heat Removal] Removal (Loops Filled and Inventory in Pressurizer, Time to Boiling Less Than 2 Hours).
During the second period, near the end of the outage from May 4 at 1:00 p.m. to May 10, 2002, at 2:30 a.m. (approximately 132 hours0.00153 days <br />0.0367 hours <br />2.18254e-4 weeks <br />5.0226e-5 months <br />), the steam generators were credited as an alternate means of decay heat removal while Unit 2 was in Mode 5 (cold shutdown), time-to-boil was greater than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, and inventory was maintained in the pressurizer. The second period was a condition specifically identified in the fourth of four Appendix G pressurized water reactor Phase 1 screening worksheets, PWR Refueling Operation RCS Level > 23' Or PWR Shutdown Operation With Time to Boil >
2 Hours and Inventory in the Pressurizer.
Both time periods affected Section I.B(1), Core Heat Removal Guidelines, Training/Procedures, of the applicable Appendix G Phase 1 worksheets, in that, when the steam generators were relied upon as an alternate means of reactor decay heat removal, safety-related SEP 3.0, Steps 5b and 8b contained inadequate guidance to ensure that the top of the secondary side of the U-tubes remained covered with water
during a loss of all AC power to a shutdown Unit. The second worksheet indicated that findings which degraded the licensees ability to establish an alternate core cooling path if decay heat removal could not be re-established required a Phase 2 SDP analysis.
The fourth worksheet indicated that findings which affected procedures for normal and abnormal decay heat removal operation were characterized as having very low safety significance (Green).
Enforcement The issue of failing to account for the impact of varying water density differences on the steam generator narrow range level detector variable leg when transitioning from hot to cold plant conditions did not present an immediate safety concern and is being treated as one technical issue with two applicable time periods. In accordance with Inspection Manual Chapter 0609, Significance Determination Process, Appendix G, Shutdown Operations Significance Determination Process,Section I, Guidance, paragraph entitled Finding Requiring Quantitative Assessment, the finding associated with the first time period (April 14, 2002, at 4:30 p.m. to April 15, 2002, at 4:45 p.m.) is being forwarded to the Region III Senior Reactor Analyst for quantitative risk assessment.
The finding associated with the second time period (May 4, 2002, at 1:00 p.m. to May 10, 2002, at 2:30 a.m.) was characterized as having very low safety significance (Green) during the Phase 1 SDP screening process. However, since one technical issue was common to both time periods and the Senior Risk Analyst had not yet completed the quantitative risk assessment at the end of the inspection period, the safety significance of the issue is To Be Determined and the issue will be considered an Unresolved Item (URI) pending completion of the quantitative risk assessment activities (URI 50-301/02-06-01).
.2 Review of Planned Outage Activities, Schedule, and Shutdown Safety Assessment (SSA)
a. Inspection Scope Prior to commencement of the Unit 2 U2R25 refueling outage, the inspectors reviewed the licensees planned outage activities and scheduling, SSA, FSAR, TSs, and system configuration controls to evaluate the adequacy of the SSA. The SSA documented a deterministic evaluation of plant risk in the areas of reactivity, core cooling, power availability, containment, inventory, RCS integrity, and SFP cooling. Relative risk was determined by the licensee based on plant configuration and the redundancy of available systems and components for each day of the outage. Inspection attributes included verifying that the licensee considered measures such as establishing compensatory actions, minimizing the duration of the activity, and obtaining appropriate onsite review committee approval. Where specific components with dual unit, cross-tie capability were rendered unavailable during integrated SI tests, the inspectors evaluated the effect on Unit 1, which was operating at full power. In addition, the inspectors reviewed two orange risk configurations concerning containment integrity on Days 4 and 6 of the outage when the containment equipment hatch was removed and either the RCS was not intact or pressurizer level was below 5 percent. The inspectors reviewed contingency plans and selected equipment for adequacy and interviewed personnel to verify that they were available to perform designated tasks.
b. Findings No findings of significance were identified.
.3 Unit 2 Shutdown, RCS Cooldown, and Transition to RHR Cooling a. Inspection Scope The inspectors observed portions of the Unit 2 down power and RCS cooldown to verify that the licensee was controlling the RCS in accordance with operating procedures.
The inspectors also conducted reviews to verify that the cooldown rate did not exceed the TS limitations. Once conditions were met, the inspectors observed the transition to RHR cooling and performed walkdowns to verify that the RHR and CCW systems were adequately removing reactor decay heat. Additionally, the inspectors toured containment to identify level instruments which were to be used in draining down the RCS to 6 inches below the reactor vessel flange. Once the instruments were identified, the inspectors checked for proper level instrument configurations to ensure that reactor vessel level would be accurately indicated. Finally, the inspectors reviewed AR 2843, TSAC [Technical Specification Action Condition] Entry in Mode 4 for RCS Loop Inoperable, which was initiated when the 'A' RCP was voluntarily removed from service during the cooldown requiring an entry into TS Action Condition 3.4.5.A for one RCS loop being inoperable.
b. Findings No findings of significance were identified.
.4 Review of Selected U2R25 Refueling and Outage Activities a. Inspection Scope The inspectors observed work activities associated with the Unit 2 refueling outage (U2R25) which began on April 13 and ended on May 14, 2002. The inspectors assessed the adequacy of outage-related activities, including configuration management, clearances and tagouts, and RCS reduced inventory operations.
Additionally, the inspectors reviewed refueling operations for implementation of risk management, preparation of contingency plans for loss of key safety functions, conformance to approved site procedures, and compliance with TSs. The inspectors also verified compliance with commitments made during licensee response to Generic Letter 88-17, Loss of Decay Heat Removal. The following major activities were observed or performed:
- outage planning meetings
- draining the RCS in preparation for reactor vessel head lift and set
- adequate reactor vessel level and temperature instrumentation during reduced inventory
- reactivity monitoring of shutdown plant conditions, including establishment of source range nuclear instrument channel check criteria
- monitoring and verification of nuclear instrument operability during core alterations
- fuel handling activities during core reload
- review of boron concentration sampling results, source range nuclear instrumentation system operability, containment closure capability, and refueling cavity water levels and clarity during fuel handling activities
- walkdowns of the RHR system during reduced inventory to verify decay heat removal capabilities
- verification of correct danger tag isolation boundaries and activities for the 2A06 safeguards bus and 2X03 high voltage auxiliary transformer maintenance activities
- walkdowns of emergency alternating current electrical power distribution systems during electrical maintenance
- walkdowns and inspection of 2A06 safeguards bus during preventative maintenance and cleaning activities
- walkdowns of the SFP cooling system after all nuclear fuel had been offloaded from the reactor to the SFP
- walkdowns of selected shutdown inventory addition makeup paths
- walkdowns of RCS boundary integrity prior to increasing reactor vessel inventory
- a review of the effect of switchyard maintenance activities on continuity of power to safeguards buses relied upon to maintain operability of RHR systems
- walkdowns to verify that all debris which could inhibit mitigating the effects of a design basis accident were removed from the primary containment
- a review of the U2R25 containment coatings assessment to verify that degraded coatings observed on the wall of the 'B' steam generator cubicle had been considered in design basis accident containment sump recirculation transport analyses
- other general outage activities, including foreign material exclusion controls and safety shutdown assessments
- heat-up observations to normal operating temperatures and pressures, including selective reviews of mode transition CLs
- a review of the core reload safety evaluation, initial criticality, and low power physics testing data.
Finally, the inspectors reviewed AR 3011, Valves Found Out of Position, which was initiated as a result of this inspection activity and discussed SFP skimmer pump suction filter pressure indicator isolation valves that were found closed despite seismic analyses in February 2000 that had determined that they should remain open for continuous filter differential pressure monitoring, a parameter described in Section 9.9 of the FSAR.
b. Findings No findings of significance were identified.
1R22 Surveillance Testing (71111.22)
.1 Unit 2 B Train ECCS Integrated SI Test
a. Inspection Scope The inspectors observed integrated SI system testing in accordance with Operations Refueling Test (ORT) 3B, Safety Injection Actuation With Loss of Engineered Safeguards AC Power (Train B) Unit 2, on April 15, 2002, to determine the ability of Unit 2 safety-related equipment to respond to a design basis accident. The inspectors also reviewed Safety Evaluation 2002-0148, ORT-3B Safety Injection Actuation With Loss of Engineered Safeguards AC Power (Train B), to evaluate the use of a dedicated operator to recover and align the G-01 EDG to support a Unit 1 design basis event. Extended observations were performed from the control room to observe engineering safeguards equipment response. The inspectors observed ECCS load sequencing, shedding, and restoration to verify that Unit 2, 'B' train ECCS equipment was capable of performing the intended design function.
The inspectors reviewed pre-test equipment alignments and plant conditions prior to starting the test to verify proper system configurations. Communication practices, control room decorum, receipt of expected alarms and warning lights, supervisory control, procedure adherence, and the interface between test and on-shift licensed personnel were observed. The inspectors observed G-04 loading, frequency, voltage, and start times to verify that the EDG was capable of satisfying design basis requirements. The inspectors observed the crew response to degraded grid conditions during the refueling test to verify that conservative decisions were made relative to maintaining both Units 1 and 2 in stable configurations. The inspectors reviewed the completed test documentation to verify that all equipment acceptance criteria had been met and all equipment remained capable of performing the intended safety function.
b. Findings The inspectors identified a finding of very low safety significance (Green) concerning ORT 3B, Safety Injection Actuation With Loss of Engineered Safeguards AC
[Alternating Current] (Train B), Revision 33, which directed a dedicated operator to perform duties away from the Unit 1, 'B' train EDG, G-03, such that the intended functions could not be performed within the bounding time limits of the Unit 1 large break loss-of-coolant accident design basis.
Description During U2R25, ORT 3B tested the 'B' Train of engineered safeguards equipment and the ability of the associated G-03 (Unit 1, 'B' Train EDG) and G-04 (Unit 2, 'B' Train EDG) EDGs to respond to design basis events. To allow testing of only one diesel at a time and to prevent a diesel from starting and running unloaded for an extended period of time, the refueling test directed disabling of the EDG not being tested during portions of the test on the remaining EDG. For instance, during Step 5.4, Loss of AC Followed By Automatic Safety Injection With G-04, G-03 was disabled.
On April 15, 2002, Unit 2 was in cold shutdown for U2R25 and Unit 1 was at full power.
The Unit 1 risk assessment indicated that with G-02 (Unit 2, 'A' train EDG) having been previously taken out-of-service due to high vibrations and G-03 (Unit 1, 'B' Train EDG)
and G-04 (Unit 2, 'B' Train EDG) removed from service for ORT 3B testing, Unit 1 would
be in a risk configuration that was approximately 23 times the zero maintenance core damage frequency risk level. In accordance with licensee Nuclear Plant Procedure (NP)
10.3.7, On-Line Safety Assessment, Revision 6, this risk level was considered a 'Red'
risk condition. To reduce the Unit 1 risk profile, the licensee performed Safety Evaluation 2002-0148, ORT 3B Safety Injection Actuation With Loss of Engineered Safeguards AC (Train B), to add procedural steps to allow restoration of the EDG not being tested in the event the diesel was needed to support Unit 1 operations.
On April 15, 2002, the inspectors were in the control room observing final preparations for ORT 3B, Step 5.4, Loss of AC Followed by Automatic Safety Injection With G-04.
The inspectors noted that Step 5.3.19.c specified that a dedicated Level 4 operator be stationed at 125-volts direct current breaker D72-28-01 in the G-03/G-04 EDG building to perform Attachment K when directed by shift management. The intent of Step 5.3.19.c was to have the dedicated operator restore 125-volts direct current control power to the G-03 EDG so that the diesel could be aligned to support automatic operation to Unit 1. The inspectors also noted that Step 5.5.1.b directed the same operator to restart the K-3B station air compressor following the previous shedding of the air compressor during step 5.4.3 of the refueling test. Using the same dedicated operator to restart the station air compressor would have necessitated the operator leaving the G-03/G-04 building on the north side of the protected area and entering the air compressor room located on the ground elevation of the turbine building between Units 1 and 2.
The inspectors expressed concern to the duty shift manager that ORT 3B was directing the G-03 dedicated operator to perform duties with the station air compressor away from the local G-03 area. Following the inspectors comments, the duty shift supervisor directed that a different auxiliary operator be assigned to perform the air compressor restoration activities. The refueling test proceeded and the dedicated G-03 operator remained in the G-03/G-04 building for the remainder of the test, locally available to perform the intended functions. One of the criteria for placing safety-related mitigating equipment in service includes sufficient time available to implement the intended actions. The G-03/G-04 building was located on the north end of the protected area, approximately 100 yards up a slight hill from the station air compressor room.
The inspectors reviewed FSAR Table 14.3.2-10, Plant Operating Range Allowed By The Best Estimate Large Break Loss-of-Coolant-Accident (LBLOCA) Analysis (Point Beach Nuclear Plant), Item g, and noted that the LBLOCA design basis assumed that the SI time delay (with loss of offsite power) to be less than or equal to 37.0 seconds for low-head SI and less than or equal to 23.0 seconds for high head SI. The inspectors compared the time frames required by the LBLOCA design basis with the time available for the dedicated operator to have restored G-03 to service, starting from the air compressor room in the turbine building. The inspectors concluded that the dedicated operator could not have reasonably completed the actions to restore G-03 to automatic operation in a time sufficient to have met the LBLOCA design basis assumptions.
The inspectors determined that the issue of providing procedural guidance to a dedicated operator to perform ancillary duties away from the designated duty station such that the intended functions could not be performed within the bounding time limits of the design basis analyses was a performance deficiency and was of more than minor
significance since the issue affected the availability and capability of the G-03 EDG, a mitigating system, to respond to Unit 1 design basis events. The inspectors used Manual Chapter 0609, Significance Determination Process, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations, regarding mitigating systems and determined that:
- The finding was not a design or qualification deficiency;
- The finding did not represent an actual loss of the safety function for any mitigating system and did not result in a loss of function of a single train of any mitigating systems for greater than its TS allowed outage time;
- The finding did not represent an actual loss of safety function of one or more non-TS trains of equipment designated as risk significant per 10 CFR 50.65 for greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />;
- The finding did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event in that the finding did not involve the loss or degradation of equipment or function specifically designed to mitigate a seismic, flooding or severe weather initiating event; and
- The finding did not involve the loss of a safety function that contributed to external event initiated core damage accident sequences.
Therefore, the finding screened as Green, very low safety significance.
Enforcement Since the inspectors intervened and the G-03 dedicated operator did not perform ancillary duties away from the assigned duty station such that the intended G-03 functions could not have been performed within the bounding time limits of the Unit 1 LBLOCA design basis, the issue did not represent a violation of NRC requirements.
Because this issue was more than a minor concern but did not involve a violation of NRC requirements, the inspectors determined that this issue constituted a Finding of very low safety significance (Green) (FIN 50-266/02-06-02).
.2 RHR Valve Exercise Prior to Placing RHR In Service During Unit 2 Shutdown a. Inspection Scope The inspectors reviewed design basis requirements and observed performance of inservice surveillance test IT 04D, RHR Valve Exercise Test for Operation or Shutdown Unit 2, Revision 4, to verify operability of the RHR suction and return valves prior to placing the system in service and to verify compliance with American Society of Mechanical EngineersSection XI testing requirements.

The inspectors reviewed Safety Evaluation 2002-0150, ORT-3A (Revision 34), Safety Injection Actuation With Loss of Engineered Safeguards AC Power Without G-02), to verify the adequacy of the test while the normal 2A05 safeguards bus power supply, EDG G-02, was out-of-service. Observations were performed from the control room to observe and verify the correct timing and sequence between interrelated engineering safeguards systems.
The inspectors reviewed pre-test equipment alignments and plant conditions to ensure proper system configurations. Communication practices, control room decorum, receipt of expected alarms and warning lights, supervisory overview, procedure adherence, and the interface between test and on-shift licensed personnel were observed. The inspectors also observed G-01 loading, frequency, voltage, and start times to verify that all design basis requirements were met. The inspectors observed the crew response to degraded grid conditions during the surveillance test to verify that conservative decisions were made relative to maintaining both Units 1 and 2 in stable configurations. The inspectors reviewed the completed test documentation to verify that all equipment acceptance criteria had been met and the equipment remained capable of performing the intended safety function.
b. Findings No findings of significance were identified.
.4 Refueling Interval Overspeed Trip Test of Unit 2 Turbine-Driven AFW Pump a. Inspection Scope
The inspectors reviewed design basis requirements and observed performance of inservice surveillance test IT 295B, Overspeed Test Turbine-Driven Auxiliary Feedwater Pump, Refueling Interval Unit 2, Revision 11, to verify operability of the Unit 2 turbine-driven AFW pump prior to exceeding 350EF following U2R25.

b. Findings No findings of significance were identified.
.5 Local Leak Rate Test of Unit 2 Containment Purge Valves a. Inspection Scope The inspectors observed performance of test TS 36, Local Leak Test of Containment Purge Valves Unit 2, Revision 15, to verify containment integrity of the purge system supply and exhaust valves prior to Unit 2 exceeding 200EF following U2R25. The inspectors walked down the test configuration and observed data collection to verify that the test methodology accurately characterized leakage from the V-1 and V-2 containment penetrations. The inspectors also walked down equipment to verify that the test equipment was within calibration, the boundaries of the leak rate test were properly tagged and controlled in accordance with the test procedure, and the leak rate test was conducted within the test parameters of 61 to 65 pounds per square inch gauge. The inspectors also reviewed test data to verify that the purge system supply and exhaust valve leakage rates met acceptance criteria and added the measured leakage to the remaining containment leakage values to verify that design basis integrated containment leakage rates were not exceeded. The inspectors reviewed completed test documentation and checked control room Binder TS-10A to verify that local leak rate test results from the containment purge system supply and exhaust valves had been properly transcribed into the record used by licensed operators.
Finally, the inspectors highlighted procedural errors in test TS 36, Step 5.5, to the test performers to ensure that purge system supply and exhaust valve leak rates were assigned to the proper Unit. The inspectors selected the containment purge supply and exhaust valves for observation due to the large impact of these valves on the Unit 2 Large Early Release Frequency.
b. Findings No findings of significance were identified.
.6 Station Battery D-05 Discharge Test a. Inspection Scope
On March 26, 2002, the inspectors observed a safety-related, red instrument bus, 125-volts direct current battery discharge test in accordance with Routine Maintenance Procedure (RMP) 9200-1, Station Battery D-05 Discharge Tests and Equalizing Charge, Revision 8, to verify that the battery capacity was adequate to supply and maintain operable status of all emergency loads for the design duty cycle. The inspectors compared the battery performance test duty cycle of RMP 9200-1, Attachment B, to the design basis duty cycle defined in FSAR Figure 8.7.2, Batteries D05, D06, D305 Duty Cycle, to verify that the RMP adequately tested design basis requirements. The inspectors also reviewed test data to verify that the battery capacity was in excess of the manufacturers rating, to verify the current surveillance interval, and to ensure that no battery capacity degradation was occurring. The inspectors monitored the licensee response to low individual cell voltages following an equalizing charge to verify that the affected cells were replaced prior to the D05 battery being returned to service.

The inspector reviewed these documents to assess the licensees ability to identify repetitive problems, contributing causes, the extent of conditions, and to implement corrective actions to achieve lasting results.
b. Findings No findings of significance were identified.
2OS2 ALARA Planning and Controls (71121.02)
.1 Radiological Work/ALARA Planning a. Inspection Scope The inspector examined the stations procedures for radiological work/ALARA planning and scheduling, and evaluated the dose projection methodologies and practices implemented for U2R25, to verify that sound technical bases for outage dose estimates existed. The inspector reviewed the stations collective exposure histories from 1976 to the present, current exposure trends from ongoing plant operations, and completed radiological work activities for U2R25 to assess current performance and outage exposure challenges.
The inspector evaluated the licensees effectiveness in exposure tracking for the outage to verify that the licensee could identify problems with its collective exposure and take actions to address them. Additionally, the inspector reviewed five radiologically significant RWP ALARA planning packages to verify that adequate person-hour estimates, job history files, lessons learned, and industry experiences were utilized in the ALARA planning process. As part of the reviews of the planning packages, the inspector reviewed Total Effective Dose Equivalent ALARA evaluations developed for upper/lower reactor cavity decontamination, reactor head underneath work, upper reactor internals lift rig inspection, and cavity seal ring demolition to assess the licensees analysis for the potential use of respiratory protection equipment during those evolutions.
b. Findings
No findings of significance were identified.
.2 Verification of Exposure Goals and Exposure Tracking System a. Inspection Scope The inspector reviewed the licensees methodology and assumptions used to develop outage exposure estimates and exposure goals for U2R25. Pre-job ALARA reviews were examined to evaluate the licensees ability to assess actual outage doses, as wellas the overall effectiveness of the work planning. The inspector compared exposure estimates, exposure goals, job dose rates, and person-hour estimates for consistency to verify that the licensee could project, and thus better control radiological exposure. The inspector examined job dose history files and dose reductions anticipated through lessons learned to verify that the licensee appropriately forecasted outage doses. The inspector examined the actual U2R25 radiation dose exposure data to date (i.e.,.41 roentgen equivalent man (Person-rem), versus the projected dose .70 person-rem) and the outage dose goal of 130 person-rem. The inspector also reviewed the licensees exposure tracking system to verify that the level of exposure tracking detail, exposure report timeliness, and exposure report distribution were sufficient to support control of collective exposures. Additionally, the inspector reviewed dose tracking records for all workers on selected projects to assess the effectiveness in maintaining individual exposures ALARA and minimizing significant dose variations across the workgroups.

3PP2 Access Control (Identification, Authorization and Search of Personnel, Packages, and Vehicles) (71130.02)
a. Inspection Scope The regional security inspector reviewed the licensees protected area access control testing and maintenance programs and selective procedures. The inspector observed licensee testing of all access control equipment located at the protected area portal to determine if testing and maintenance practices were effective and performance based.
On at least two occasions, during peak ingress periods, the inspector observed in-processing search of personnel, packages, and vehicles at the licensees protected area portal to determine if those practices were conducted in an effective manner and were in accordance with regulatory requirements. Interviews with randomly selected security personnel were conducted and records were reviewed to verify that security staffing levels were consistently and appropriately implemented. Also the inspector reviewed the licensees process for limiting access to only authorized personnel to the protected area and vital equipment by a selected sample review of access authorization lists and actual vital area entries.

4OA2 Identification and Resolution of Problems (71152)
.1 Initial Licensee Response to Density Compensation Errors Associated With The Use of Steam Generator Narrow Range Level Detector During Cold Shutdown Plant Conditions a. Inspection Scope During the week of June 3, 2002, the inspectors reviewed the licensee response to the inspectors discovery of previously unnoticed density compensation errors associated with the steam generator narrow range level indication during cold plant conditions. The inspectors reviewed the licensee's response to assess internal communication capabilities, the ability of the licensee to perform adequate extent-of-condition reviews, and the ability of the licensee to understand the full impact of the issue on plant operations.
a. Findings As discussed in Section 1R20.4 of this report, on April 26, 2002, during U2R25 the inspectors identified that the steam generator narrow range level detectors, calibrated for normal, hot steam generator operating conditions of 521EF and 821 pounds per square inch absolute, were being used during cold plant conditions to satisfy TS surveillance requirements 3.4.5.2, 3.4.6.2, and 3.4.7.2. As a result of this error, as steam generator water temperatures decreased (and level detector variable leg water densities increased) during a plant shutdown and cooldown, the difference between the steam generator narrow range indicated and actual steam generator water level increased in the non-conservative direction. At 200 EF, this unaccounted density error resulted in a condition where the actual water level was 4 percent lower (closer to the top of the U-tube bundle) than indicated.
As a result of the inspectors observation, a licensee instrumentation and control engineer initiated AR 3112, Steam Generator Narrow Range Level Uncertainty at Lower Temperature, on April 30, 2002. In the AR, the engineer acknowledged the inspectors observation and recommended that the parametric value for the steam generator narrow range level indication in Engineering Evaluation 2001-0032, Parametric Values, Revision 2, be changed from 33 percent to 38 percent in Modes 3, 4, and 5. The licensed senior reactor operator who screened the AR on April 30 recommended that calculations be verified to ensure that logs, mode change CLs, and TSs were changed as required. The senior reactor operator determined that Unit 2
steam generators were operable on April 30 since the Unit was in Mode 6 (refueling shutdown) and the steam generators were not required as a method of decay heat removal for the associated plant conditions. The senior reactor operator also noted that steam generator level indication might be required when Unit 2 subsequently returned to Mode 5 (cold shutdown) following refueling activities. The inspectors reviewed licensee procedure changes following initiation of AR 3112 and noted that on May 1, 2002, procedure feedback Form 2002-00746 revised the control room daily log sheet, Stations 148 through 153, to change the minimum required steam generator narrow range level indication to greater than or equal to 38 percent narrow range in Modes 3, 4, and 5.
Action request 3112 was screened by the management review committee on May 2, 2002, and a Level B Apparent Cause Investigation was assigned in accordance with procedure NP 5.3.1, Action Request Process, Revision 19. The licensee completed the apparent cause evaluation on May 16 and concluded that a contributing cause of the density error was a failure in the communication process between Improved TS implementation and engineering personnel to precisely define the conditions of use and the limitations associated with the steam generator narrow range level indication instrument. The extent-of-condition review associated with the apparent cause evaluation for AR 3112 did not identify any other plant procedures needing revision as a result of the steam generator narrow range level detector density compensation issue.
On May 22, 2002, the inspectors reviewed selected plant procedures to check the rigor of the previous extent-of-condition reviews concerning the steam generator narrow range level instrument density compensation issue. The inspectors identified that safety-related shutdown procedure SEP [Shutdown Emergency Procedure] 3.0 Loss of All AC [Alternating Current] Power to a Shutdown Unit - Unit 1, Revision 12, and SEP 3.0, Loss of All AC Power to a Shutdown Unit - Unit 2, Revision 13, Steps 5.b and 8.b, utilized steam generator narrow range level indication values of 29 percent to ensure that the secondary side of the top of the U-tubes remained covered with water to support use of the steam generator as a secondary heat sink and for reactor decay heat removal via natural circulation. As discussed in Section 1R20.4 of this report, SEP 3.0 created the possibility of uncovering the secondary side of the top of the steam generator U-tubes thereby impacting the ability to remove reactor decay heat. The inspectors provided the SEP 3.0 observations to licensee instrumentation and control engineering and operations personnel on May 23.
Following the inspectors observations of May 22, the licensee re-performed extent-of-condition reviews and wrote 12 other procedure feedback forms for the following safety-related procedures;
- IT 03C, HHSI [High Head Safety Injection] Check Valve Exercise Test in Cold Shutdown - Unit 1, Revision 4
- IT 04C, HHSI Check Valve Exercise Test in Cold Shutdown - Unit 2, Revision 5
- IT 03B, LHSI [Low Head Safety Injection] Valve Exercise Test in Cold Shutdown Unit 1, Revision 7
- IT 04B, LHSI Valve Exercise Test in Cold Shutdown Unit 1, Revision 6
- TS Test TS 30, High and Low head Safety Injection Check Valve Leakage Test Unit 1, Revision 23
- TS 31, High and Low Head Safety Injection Check Valve Leakage Test Unit 2, Revision 23
- Operations Refueling Test (ORT) 3B, Safety Injection Actuation With Loss of Engineering Safeguards AC (Train B) Unit 2, Revision 33
- ORT 3B, Safety Injection Actuation With Loss of Engineering Safeguards AC (Train B) Unit 1, Revision 32
- ORT 3A, Safety Injection Actuation With Loss of Engineering Safeguards AC (Train A) Unit 1, Revision 35
- ORT 3A, Safety Injection Actuation With Loss of Engineering Safeguards AC (Train A) Unit 2, Revision 34 The inspectors concluded, based on the May 22 observation concerning SEP 3.0 and the number of procedures requiring revision once the extent of condition reviews had been re-performed, that the licensee's initial extent of condition review concerning the density compensation issue had not been sufficiently rigorous to identify the full impact of the issue on plant operations. The inspectors noted that failure in the internal communication process that contributed to procedure revisions delays was also the same apparent cause identified in AR 3112, making the rigor of internal communication processes a repeat issue.
4OA3 Event Follow-up (71153)
.1 (Closed) LER 301/2002-001-00: Completion of Nuclear Plant Shutdown Required By Limiting Condition for Operation 3.5.2 Required Action B.1. On February 20, 2002 at approximately 1:00 a.m., the Unit 2 'B' train safety injection pump, 2P-15B, was damaged during licensee performance of a monthly preventative maintenance procedure to ensure bearing lubrication. Technical Specification Action Condition 3.5.2.A.1 was entered which required an inoperable emergency core cooling train be restored to an operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Subsequent inspection of the pump revealed damage to the rotating element, the coupling and shaft keys between the pump and the motor, the pump internal wearing rings, and other components. The licensee concluded that the cause of the pump damage was gas binding as a result of back-leakage of nitrogen-saturated fluid from the 'A' SI accumulator, 2T-34A, through two or more check or closed valves to the discharge of the SI pump. When it became apparent that pump repairs and testing would exceed the TS Action Condition completion time, the licensee shutdown Unit 2. Unit 2 reached Mode 3, hot standby, at 7:26 p.m. on February 22, 2002, approximately 66 hours7.638889e-4 days <br />0.0183 hours <br />1.09127e-4 weeks <br />2.5113e-5 months <br /> after the 2P-15B SI pump failed on February 20. The shutdown occurred without complications and all equipment required for the shutdown performed as expected.
Inspector reviews of the SI pump failure, corrective action program deficiencies, and the associated operability evaluation were documented in NRC Inspection Report 50-266/02-03(DRP), 50-301/02-03(DRP); Section 4OA2.c.(2); Inspection Report 50-266/02-05(DRP), 50-301/02-05(DRP); Sections 1R14.1, 1R15.1, 1R15.2, and 4OA2.1; Inspection Report 50-266/02-05(DRP), 50-301/02-05(DRP); and letters dated May 14 and June 13, 2002. The inspector review of this LER did not identify any new
issues. The 2P-15B SI pump failure and the forced Unit 2 shutdown were entered into the licensees corrective action program (CAP) as CAP 002245.
4OA5 Other
.1 Circumferential Cracking of Reactor Pressure Vessel Head Penetration Nozzles (Temporary Instruction 2515/145)
a. Inspection Scope The inspectors performed a review of the licensees activities in response to NRC Bulletin 2001-01, Circumferential Cracking of Reactor Pressure Vessel Head Penetration Nozzles, to verify compliance with applicable regulatory requirements. In accordance with the Bulletin, Point Beach Nuclear Plant Unit 2 was characterized as belonging to the sub-population of plants (Bin 3) that were considered to have a moderate susceptibility to primary stress corrosion cracking based upon a susceptibility ranking of more than 5 but less than 30 effective full power years of operation from that of the Oconee Nuclear Station, Unit 3, condition. As a result, Point Beach responded to the Bulletin by performing a direct visual examination of the reactor vessel head. The inspectors interviewed inspection personnel, reviewed procedures and inspection reports, including photographic and video tape documentation, to assess the licensees efforts in conducting an effective visual examination of the reactor vessel head.
Evaluation of Inspection Requirements (1) Were the licensees examinations performed by qualified and knowledgeable personnel?
The inspectors determined that the examinations were performed by personnel certified as Level II or Level III VT-2 in accordance with the Point Beach Nuclear Plant Nondestructive Examination Procedures Manual. In addition, the licensee provided the individuals with training specific to the guidelines described by the Electric Power Research Institute, Visual Examination for Leakage of PWR Reactor Head Penetrations.
(2) Were the licensees examinations performed in accordance with approved and adequate procedures?
The inspectors verified that the examinations were conducted in accordance with plant approved, Nondestructive Examination Procedure, NDE-757, Revision 0,
"Visual Examination for Leakage of Reactor Pressure Vessel Closure Head Penetrations. The inspectors determined that the procedure was appropriate for the examinations. In addition, the licensee constructed a full-size training mockup of the reactor head to familiarize the personnel involved with asbestos insulation removal and the subsequent visual examination.
(3) Were the licensees examinations adequately able to identify, disposition, and resolve deficiencies?
The inspectors determined through a review of post-examination records in the form of video tape and pictures, discussions with the personnel that conducted the examinations, and a review of the procedure, that the examinations were sufficient to identify any deficiencies. The licensees examinations did not identify any deficiencies, therefore, the inspectors did not assess the licensees efforts to disposition or resolve deficiencies.
(4) Were the licensees examinations capable of identifying the primary stress corrosion cracking phenomenon described in the Bulletin?
The inspectors determined through interviews with inspection personnel, and reviews of procedures and inspection reports, including video tape and photographic documentation of the examinations, that the licensees efforts were capable of identifying the results of the phenomenon described in the Bulletin.
The inspectors determined that the inspection personnel had access to all the head penetrations, 49 in total plus the 3/4" head vent, with no obstructions or interferences.
(5) What was the condition of the reactor vessel head (debris, insulation, dirt, boron from other sources, physical layout, viewing obstructions)?
The Point Beach Unit 2 reactor pressure vessel had 3-inch thick block contoured asbestos insulation. The 3" blocks were in direct contact with the head; however they were not bonded to the head. The blocks were coated with 1/4" Fiberfax cement which was sealed with a waterproof coating. The inspectors determined that prior to the examinations, the licensee completely removed the insulation.
The inspectors also determined through discussions with the inspection personnel and viewing of the videotape that the as-found pressure vessel head condition was relatively clean (with only bits of insulation and cement present),
with no viewing obstructions to the exam. The inspection personnel fully examined the 49 pressure vessel head penetrations, including the 3/4" head vent.
(6) Could small boron deposits, as described in the Bulletin, be identified and characterized?
The inspectors verified, through interviews with inspection personnel and review of the video tape and photographic record of the examination, that small boron deposits, as described in the Bulletin, could be identified; given the cleanliness and accessibility of the pressure vessel head penetrations. However, no indications were found on the 49 pressure vessel head penetrations, including the 3/4" head vent.
(7) What materiel deficiencies (associated with the concerns identified in the Bulletin) were identified that required repair?
Through a review of the examination records, the inspectors determined that the inspection personnel did not identify any materiel deficiencies associated with any of the 49 pressure vessel head penetrations, including the 3/4" head vent.
(8) What, if any, significant items that could impede effective examinations and/or ALARA issues were encountered?
The inspectors verified that, upon removal of the asbestos head insulation, there were no impediments to the examinations. Radiation doses received as a part of the examinations included 3.484 person-rem, associated with removal of the insulation/visual inspection, 0.634 person-rem for shroud removal, and 0.728 person-rem for installation of new insulation. The shroud and new insulation will have 6 viewing ports installed to further aid future inspections of the head and to reduce dose associated with insulation removal.

Subject: Biennial Heat Sink Change to Inspection Findings: No 4OA7 Licensee-Identified Violations The following finding of very low significance was identified by the licensee and was a violation of NRC requirements which met the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as a Non-Cited Violation.
If you deny this Non-Cited Violation, you should provide a response with the basis for denial, within 30 days of the date of this inspection report, to the Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 2055-0001; with copies to the Regional Administrator, Region III; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 2055-0001, and the NRC Resident Inspector at Point Beach.
Requirement Licensee Failed to Meet Code of Federal Regulations 10 CFR Part 50, Appendix R, Fire Protection Program for Nuclear Power Facilities Operating Prior to January 1, 1979,Section III.L.2.b, Alternative and Dedicated Shutdown Capability, requires, in part, that the reactor coolant makeup function be capable of maintaining the reactor coolant level within the level indication in the pressurizer for PWRs
[Pressurized Water Reactors]. Contrary to this requirement, failure of the licensee to have sufficient nitrogen back-up capacity available for the charging pump speed control function resulted in the inability of the licensee to maintain pressurizer level above zero percent indicated level for approximately a 2.5 hour5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br /> period during an Appendix R safe shutdown scenario.
