|
| ==Dear Mr. McCarthy:== | | ==Dear Mr. McCarthy:== |
| On December 31, 2007, the U.S. Nuclear Regulatory Commission (NRC) completed an integrated inspection at your Point Beach Nuclear Plant, Units 1 and 2. The enclosed inspection report documents the inspection results, which were discussed on January 10, 2008, with you and members of your staff. The inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations, and with the conditions of your license. The inspectors reviewed selected procedures and records, observed activities, and interviewed your personnel. Based on the results of this inspection, seven NRC-identified and self-revealed findings of very low safety significance (Green) were identified. Five of these findings were determined to involve violations of NRC requirements. However, because of the very low safety significance and because they are entered into your corrective action program, the NRC is treating these findings as Non-Cited Violations (NCVs), consistent with Section VI.A.1 of the NRC Enforcement Policy. If you contest any NCV in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001, with a copy to the Regional Administrator, U.S. Nuclear Regulatory Commission - Region III, 2443 Warrenville Road, Suite 210, Lisle, IL 60532-4352; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the Resident Inspector Office at the Point Beach Nuclear Plant. In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records System (PARS) component of NRC's document system (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room). | | On February 13, 2007, the U.S. Nuclear Regulatory Commission (NRC) issued Integrated Inspection Report 05000266/2007005 and 05000301/2007005 (ML080450234) for your Point Beach Nuclear Plant, Unit 1 and Unit 2. Inspection report sections documenting the completion of a periodic evaluation of maintenance effectiveness and the completion of the baseline Emergency Preparedness biennial program inspection were inadvertently omitted in the original report. The enclosed errata contain the omitted sections and should be inserted as Pages 15(a), 15(b), 25(a), 25(b), 32(a) and Attachment pages 17 through 20, where appropriate, into Integrated Inspection Report 05000266/2007005 and 05000301/2007005. |

| =SUMMARY OF FINDINGS=
| |
| IR 05000266/2007005, 05000301/20070005; 10/01/2007-12/31/2007; Point Beach Nuclear Plant, Units 1 & 2; Adverse Weather Protection; Operability Evaluations; Followup of Events; Other Activities. This report covers a three-month period of inspections by resident inspectors and regional specialists. Seven Green findings were identified. Five of the findings which were identified had associated Non-Cited Violations (NCVs). The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, "Significance Determination Process," (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process," Revision 4, dated December 2006.

| ===A. NRC-Identified and Self-Revealing Findings===
| |
| | |
| ===Cornerstone: Initiating Events===
| |
| : '''Green.'''
| |
| The inspectors identified a finding of very low safety significance with no associated violation of regulatory requirements for the licensee's failure to control loose materials in the protected area. Specifically, the inspectors identified materials that were classified as tornado hazards per station procedure PC 99 near the Unit 1 and Unit 2 main and auxiliary transformers and the switchyard boundary. Once notified, the licensee entered the issue into its corrective action program and removed the materials. In addition, a procedure change request was initiated to incorporate tornado hazard walkdowns into the abnormal operating procedure for severe weather response. The finding is more than minor because if left uncorrected, the loose items would become a more significant safety concern. The finding is of very low safety significance (Green) because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions will not be available. Additionally, the inspectors determined that the finding had a cross-cutting aspect in the area of problem identification and resolution in that the licensee failed to take appropriate corrective actions to address safety issues and adverse trends in a timely manner, commensurate with their safety significance and complexity (P.1(d)). (Section 1R01.1)
| |
| | |
| ===Cornerstone: Mitigating Systems===
| |
| : '''Green.'''
| |
| A self-revealed finding with no associated violation of regulatory requirements was identified for an inadequate operability evaluation performed in June 2007 for service water pump P-32C. Specifically, the pump failed its inservice test (IST) on high vibrations after approximately six hours of operation, but the operability evaluation had concluded the pump vibrations would not reach the out-of-service limit until after 120 hours of continuous operation. Contributing to the unanticipated early failure was the use of non-conservative decision-making and the use of a non-conservative assumption in the pump's vibration prediction model. The licensee entered this issue into its corrective action program and P-32C was subsequently repaired and returned to service.
| |
| | |
| The finding is more than minor because it could reasonably be viewed as a precursor to a significant event. The finding is of very low safety significance (Green) because there was no design deficiency, no actual loss of safety function, no single train loss of safety function for greater than the Technical Specification (TS) allowed outage time, and no risk due to external events. Additionally, the inspectors determined that the finding had a cross-cutting aspect in the area of human performance. Specifically, the licensee failed to use conservative assumptions in decision-making affecting operability of safety-related equipment (H.1(b)). (Section 1R15.1)
| |
| : '''Green.'''
| |
| The inspectors identified a finding of very low safety significance (Green) and an associated Non-Cited Violation of 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the failure to adequately assess operability of the Unit 2 2P-29 turbine-driven auxiliary feedwater (TDAFW) pump.
| |
| | |
| The licensee failed to implement procedural requirements regarding the immediate assessment of operability on September 24 and September 27, 2007, for the increased water ingress into the turbine outboard bearing housing for the pump following maintenance activities. The licensee took corrective actions, which included performing an operability evaluation on November 1 when the next scheduled test again revealed higher than normal levels of water in the bearing oil. However, the inspectors continued to identify, in the subsequent revisions to the operability determination, that the licensee failed to utilize all the data available to assess pump operability. At the end of the inspection period, the licensee continued to evaluate the causes and corrective actions to address this finding. The finding is more than minor because, if left uncorrected, the failure to properly assess operability would result in the TDAFW pump being degraded, and possibly inoperable for more than the allowed outage time in accordance with TSs with no action being taken. The finding is of very low safety significance (Green) because the inadequate operability determination did not result in exceeding the allowed outage time of TSs before action was taken. Additionally, the inspectors determined that the finding had a cross-cutting aspect in the area of human performance. Specifically, the licensee failed to use conservative assumptions in decision-making affecting operability of safety-related equipment (H.1(b)). (Section 1R15.2)
| |
| : '''Green.'''
| |
| A self-revealed finding and an associated Non-Cited Violation of 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," were identified for the failure to have adequate procedures to allow operators to properly set the thermostat of the Unit 2 refueling water storage tank (RWST) heaters and to ensure the RWST was recirculated frequently enough for the temperature indicator to accurately measure bulk temperature. On September 18, 2007, the Unit 2 RWST was found to be at 105
| |
| °F. This temperature exceeded the TS-maximum allowable limit of 100
| |
| °F (97 °F parametric) and could not be restored to acceptable limits before the eight-hour TS action statement expired. As a result, a shutdown of Unit 2 was commenced. At 20 percent power, a return to full power began after the RWST temperature was restored to within acceptable limits. It was later identified that the undesired heat-up was caused by the incorrect setting of the controlling thermostat for the RWST heaters.
| |
| | |
| The finding is more than minor because it is associated with the procedure quality and human performance attributes of the Mitigating Systems Cornerstone and affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). The finding is of very low safety significance (Green) because the elevated temperature of the RWST and subsequent shutdown sequence did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available. Additionally, the inspectors determined that the finding had a cross-cutting aspect in the area of human performance. Specifically, human error prevention techniques were not utilized prior to and during the thermostat setting task and personnel proceeded in the face of uncertainty and unexpected circumstances (H.4(a)). (Section 4OA3.1)
| |
| : '''Green.'''
| |
| The inspectors identified a finding of very low safety significance and an associated Non-Cited Violation of 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the licensee's failure to conduct adequate post-maintenance testing of the Unit 1 1P-29 turbine-driven auxiliary feedwater (TDAFW) pump following a ten-year overhaul of the turbine in May 2007. Specifically, the ten-year overhaul maintenance included bearing replacement, but the TDAFW pump was not run long enough during testing for bearing temperature to stabilize. The appropriate post-maintenance test would have detected that the bearing temperatures were rising and required evaluation prior to declaring the TDAFW pump operable. The licensee entered the issue into its corrective action program and took immediate corrective actions. Additionally, the licensee initiated changes to the inadequate procedures.
| |
| | |
| The finding is more than minor because, if left uncorrected, the issue would have become a more significant safety concern. The inspectors determined this finding was not a design qualification deficiency resulting in a loss of function per NRC Generic Letter 91-18, did not represent an actual loss of safety function of a system or train of equipment, and was not potentially risk-significant due to a seismic, fire, flooding, or severe weather initiating event. Therefore, the finding is considered to be of very low safety significance (Green). Additionally, the inspectors determined that the finding had a cross-cutting aspect in the area of human performance. Specifically, the licensee failed to ensure that procedures were adequate and accurate to assure nuclear safety (H.2(c)). (Section 4OA5.1)
| |
| : '''Green.'''
| |
| The inspectors identified a finding of very low safety significance and an associated Non-Cited Violation of 10 CFR 50, Appendix B, Criterion XVI, "Corrective Action," for the failure to implement prompt corrective actions for the degraded oil conditions initially identified with the Unit 2 2P-29 turbine-driven auxiliary feedwater (TDAFW) pump on September 24, 2007, following maintenance. Following an additional oil sample with favorable results, the licensee incorrectly concluded, due to confirmational biases, that the high water content of the first oil sample was an expected condition. The licensee wrote a condition report, but it was closed with no actions taken. In November 2007, the licensee identified that a significant degraded oil condition existed with the pump. The licensee entered the issue into its corrective action program and took immediate corrective actions, including rebuilding the pump turbine. The licensee continued to evaluate the causes and corrective actions to address this finding at the end of the inspection period.
| |
| | |
| The finding is more than minor because it could reasonably be viewed as a precursor to a significant event. Specifically, the failure to correct the cause of the oil degradation in a timely manner in September 2007 could have resulted in the failure of the 2P-29 TDAFW pump. The finding is of very low safety significance (Green) because there was no design deficiency, no actual loss of safety function, no single train loss of safety function for greater than the TS allowed outage time, and no risk due to external events. Additionally, the inspectors determined that the finding had a cross-cutting area aspect in the area of problem identification and resolution. Specifically, the licensee failed to thoroughly evaluate the problem with water ingress into the oil, such that a resolution addressed the cause and extent of condition (P.1(c)). (Section 4OA5.2.b.1)
| |
| | |
| ===Cornerstone: Other===
| |
| : '''Green.'''
| |
| The inspectors identified a finding of very low safety significance and an associated Non-Cited Violation of 10 CFR 72.48(c)(1) for the licensee's failure to obtain a Certificate of Compliance (CoC) amendment pursuant to 10 CFR 72.244, for changes made in the spent fuel storage cask operating procedures during the 2004 loading campaign as described in the Final Safety Analysis Report. The procedure changes constituted a change in the terms, conditions, or specifications incorporated in the CoC. Although the procedures were contained in the Final Safety Analysis Report, the licensee failed to identify that TS 1.2.17a, "32PT Dry Storage Canister (DSC) Vacuum Drying Duration Limit," was also affected by the procedure change and required prior NRC approval. The licensee implemented corrective actions, which included revising the loading procedure to reflect the sequence described in the FSAR prior to the next cask loading campaign.
| |
| | |
| This finding is more than minor because it had the potential to impact the NRC's ability to perform its regulatory function, since the licensee failed to receive NRC approval for a change in this licensed activity. The inspectors determined that the finding was not suitable for SDP evaluation because the noncompliance involved 10 CFR Part 72 dry fuel storage activities. Therefore, this finding was reviewed by regional management and dispositioned using traditional enforcement. The finding was determined to be of very low safety significance (Green). (Section 4OA5.5)

| ===.1 Readiness For Impending Adverse Weather Condition - High Wind Conditions===
| |
| | |
| ====a. Inspection Scope====
| |
| Because high winds were forecast in the vicinity of the facility for October 18, 2007, the inspectors reviewed the licensee's overall preparations for the expected weather conditions. The inspectors walked down important outdoors areas within the protected area, in addition to the licensee's emergency alternating current (AC) power systems, because safety-related functions could be affected by, or required as a result of, high winds or tornado-generated missiles. The inspectors focused on the licensee's procedures used to respond to specified adverse weather conditions and toured the plant grounds for loose debris, which could become missiles during a tornado or high winds condition. The inspectors evaluated the licensee's preparations against the site's procedures and evaluated the adequacy of the staff's response. The inspectors also verified that the licensee was identifying adverse weather issues at an appropriate threshold and entering them into its corrective action program in accordance with station procedures. This inspection constituted one sample prior to the onset of an adverse weather.
| |
| | |
| ====b. Findings====
| |
| | |
| =====Introduction:=====
| |
| The inspectors identified a finding of very low safety significance (Green) for the licensee's failure to control loose materials in the protected area. Specifically, the inspectors identified materials that were classified as tornado hazards per licensee procedure PC 99 and were near the Unit 1 and Unit 2 main and auxiliary transformers and the switchyard boundary. No violation of regulatory requirements occurred.
| |
| | |
| =====Description:=====
| |
| On October 18, 2007, the inspectors conducted a walkdown of the risk significant portions of the main and auxiliary power system to assess the licensee's preparations to preclude or minimize potential damage from high winds associated with severe storms or tornadoes. During the walkdown, the inspectors identified a significant quantity of unsecured materials meeting the definition of tornado hazards provided in 7 Enclosure Point Beach procedure PC 99, "Tornado Hazards Inspection Checklist," near the subject transformers. The inspectors concluded that high winds or tornadoes combined with the proximity of the transformers to the large quantity of unsecured materials increased the potential to damage the transformers or related electrical equipment. The inspectors informed the licensee of the concern and the licensee took immediate corrective action to clean the areas identified by the inspectors and entered the issue into the corrective action program as corrective action program document (CAP, condition report) CAP 01114731. The licensee also commenced a walkdown of outside areas within the protected area to address extent of condition. In addition, the licensee initiated a procedure change request to incorporate tornado hazard walkdowns into Abnormal Operating Procedure (AOP) 13C, "Severe Weather Conditions."
| |
| | |
| =====Analysis:=====
| |
| The inspectors determined that the failure of licensee personnel to control material in the protected area near risk significant equipment is a performance deficiency. Using the guidance contained in Inspection Manual Chapter (IMC) 0612, "Power Reactor Inspection Reports." Appendix B, "Issue Disposition Screening," dated September 20, 2007, the inspectors determined that the finding is more than minor because, if left uncorrected, the loose items in the vicinity of the main and auxiliary transformers, and near the switchyard, would become a more significant safety concern.
| |
| | |
| The inspectors determined that the finding warranted evaluation using the Significance Determination Process (SDP) because the finding is associated with an increase in the likelihood of an initiating event. The inspectors evaluated the finding using IMC 0609, Appendix A, Attachment 1, "Significance Determination of Reactor Inspection Findings for At-Power Situations,"
| |
| dated January 10, 2008. Using the Phase 1 SDP worksheet for the Initiating Event Cornerstone, transient initiator contributor, the inspectors determined that the finding did not contribute to the likelihood of a primary or secondary system loss of coolant accident initiator; the finding did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions will not be available; and the finding did not increase the likelihood of a fire or internal or external flooding. Therefore, the finding is determined to be of very low safety significance (Green). The inspectors performed a review of past corrective action program documents to assess the effectiveness of the licensee's corrective actions to address similar issues. During this review, inspectors noted that an NRC-identified finding, 05000266/000301-2006004-01, was issued in July 2006 for a nearly identical issue related to the failure to control loose material in the protected area. Procedure PC 99 was created as a corrective action for that finding. In addition, inspectors noted that between May and September 2007, there have been a number of CAPs written as a result of the identification of tornado hazards in the protected area during the use of procedure PC 99. Consequently, the inspectors determined that the finding had a cross-cutting aspect in the area of problem identification and resolution. Specifically, the licensee failed to take appropriate corrective actions to address safety issues and adverse trends in a timely manner, commensurate with their safety significance and complexity (P.1(d)).
| |
| | |
| =====Enforcement:=====
| |
| The failure to maintain the protected area free of tornado hazards was not an activity affecting quality subject to 10 CFR Part 50, Appendix B, nor was a procedure required by license conditions or TSs violated. Therefore, while a performance deficiency existed, no violation of regulatory requirements occurred. This is considered a finding of very low safety significance (FIN 05000266/2007005-01; 8 Enclosure 05000301/2007005-01). The licensee included this finding in its corrective action program as CAP 01114731.
| |
| | |
| ===.2 Winter Seasonal Readiness Preparations===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors conducted a review of the licensee's preparations for winter conditions to verify that the plant's design features and implementation of procedures were sufficient to protect mitigating systems from the effects of adverse weather. Documentation for selected risk-significant systems was reviewed to ensure that these systems would remain functional when challenged by inclement weather. During the inspection, the inspectors focused on plant specific design features and the licensee's procedures used to prepare for the onset of cold weather. Additionally, the inspectors reviewed licensee corrective actions for areas in the plant which previously had cold weather issues. Cold weather protection equipment, such as the façade freeze heat tracing and temporary area heaters, were verified to be in operation when applicable. The inspectors also reviewed corrective action program items to verify that the licensee was identifying cold weather issues at an appropriate threshold and entering them into the corrective action program in accordance with procedures. The inspectors' reviews focused specifically on the following plant systems due to their risk significance or susceptibility to cold weather issues: main steam system and instrumentation, including the atmospheric steam dumps and the main steam isolation valve; emergency core cooling system, including the refueling water storage tank and associated piping; and the façade freeze system. This inspection constituted one winter seasonal system readiness sample.

| |
| ===.1 Quarterly Partial System Walkdowns===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors performed partial walkdowns of accessible portions of risk-significant systems to determine the operability of these systems. The inspectors utilized system valve lineup and electrical breaker checklists, tank level books, plant drawings, and selected operating procedures to determine whether the systems were correctly aligned to perform the intended design functions. The inspectors also examined the material condition of the components and observed operating equipment parameters to determine whether deficiencies existed. The inspectors reviewed completed work orders (WOs) and calibration records associated with the systems for issues that could affect component or train functions. The inspectors used the information in the appropriate sections of the Final Safety Analysis Report (FSAR) to determine the functional requirements of the system. Partial system walkdowns of the following systems constituted two inspection procedure samples:
| |
| * Emergency diesel generator (EDG) G01 aligned to busses 1A05 and 2A05 while EDG G02 was out-of-service the week of October 22, 2007; and
| |
| * EDG G02 aligned to busses 1A05 and 2A05 while EDG G01 was out-of-service the week of November 19, 2007.
| |
| | |
| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.2 Semi-Annual Complete System Walkdown===
| |
| | |
| ====a. Inspection Scope====
| |
| In November 2007, the inspectors performed a complete system alignment inspection of the auxiliary feedwater (AFW) system for Units 1 and 2 to verify the functional capability of the system. This system was selected because it was considered both safety-significant and risk-significant in the licensee's probabilistic risk assessment. The inspectors walked down the system to review mechanical and electrical equipment line-ups, electrical power availability, system pressure and temperature indications, component labeling, component lubrication, component and equipment cooling, hangers and supports, operability of support systems, and to ensure that ancillary equipment or debris did not interfere with equipment operation. A review of past and outstanding WOs was performed to determine whether any deficiencies significantly affected system function. In addition, the inspectors reviewed the CAP database to ensure that system equipment alignment problems were being identified and appropriately resolved. The documents used for the walkdown and issue review are listed in the attached List of Documents Reviewed.
| |
| | |
| These activities constituted one complete system walkdown inspection procedure sample.

| |
| {{IP sample|IP=IP 71111.05Q}}
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors conducted fire protection walkdowns, which focused on the following attributes: the availability, accessibility, and condition of fire fighting equipment; the control of transient combustibles and ignition sources; and the condition and status of installed fire barriers. The inspectors selected fire areas for inspection based on the area's overall fire risk contribution, as documented in the Individual Plant Examination of External Events, or the potential of a fire to impact equipment that could initiate a plant transient. In addition, the inspectors assessed these additional fire protection attributes during walkdowns: fire hoses and extinguishers were in the designated locations and available 10 Enclosure for immediate use; unobstructed fire detectors and sprinklers; transient material loading within the analyzed limits; and fire doors, dampers, and penetration seals in satisfactory condition. The inspectors also determined whether minor issues identified during the inspection were entered into the licensee's corrective action program.
| |
| | |
| The walkdown of the following selected fire zones constituted three inspection procedure samples:
| |
| * Unit 2 TDAF Room
| |
| * EDG G01 Room
| |
| * EDG G02 Room
| |
| | |
| ====b. Findings====

| ===.2 Annual Fire Protection Drill Observation===
| |
| {{IP sample|IP=IP 71111.05A}}
| |
| | |
| ====a. Inspection Scope====
| |
| During this quarter, the inspectors observed two fire brigade activation drills: an October 9, 2007, drill scenario that simulated a fire in the Unit 2 2P-2C charging pump room and a November 26 drill scenario that simulated a fire in the unit common cable spreading room. The combined drill observations were used to determine the readiness of the plant fire brigade to fight fires. The inspectors verified that the licensee staff identified deficiencies, openly discussed them in a self-critical manner at the drill debriefs, and took appropriate corrective actions. Specific attributes evaluated were:

| ===.1 Resident Inspector Quarterly Review===
| |
| | |
| ====a. Inspection Scope====
| |
| In November 2007, the inspectors observed a crew of licensed operators in the plant's simulator during licensed operator training to verify that operator performance was adequate, evaluators were identifying and documenting crew performance problems, and training was being conducted in accordance with licensee procedures. The inspectors evaluated the following areas:
| |
| * licensed operator performance;
| |
| * crew's clarity and formality of communications;
| |
| * ability to take timely actions in the conservative direction;
| |
| * prioritization, interpretation, and verification of annunciator alarms;
| |
| * correct use and implementation of abnormal and emergency procedures;
| |
| * control board manipulations;
| |
| * oversight and direction from supervisors; and
| |
| * ability to identify and implement appropriate TS actions and Emergency Plan actions and notifications. The crew's performance in these areas was compared to pre-established operator action expectations and successful critical task completion requirements.
| |
| | |
| This inspection constituted one quarterly licensed operator requalification program sample.
| |
| | |
| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.2 Facility Operating History===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors reviewed the plant's operating history from September 2005 through October 2007 to identify operating experience that was expected to be addressed by the 12 Enclosure Licensed Operator Requalification Training (LORT) program. It was then verified that the identified operating experience had been addressed by the facility licensee in accordance with the station's approved Systems Approach to Training (SAT) program to satisfy the requirements of 10 CFR 55.59(c), "Requalification program requirements."
| |
| | |
| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.3 Licensee Requalification Examinations===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors performed a biennial inspection of the licensee's LORT test/examination program for compliance with the station's SAT program that would satisfy the requirements of 10 CFR 55.59(c)(4), "Evaluation." The inspectors reviewed the 2006 biennial written requalification examinations and 2007 annual operating test material to evaluate general quality, construction, and difficulty level. The written examinations reviewed consisted of four written examinations, each containing 30 questions. The operating examination material consisted of 6 operating tests, each containing approximately two dynamic simulator scenarios and five job performance measures (JPMs). The inspectors reviewed the annual requalification operating test and biennial written examination material to evaluate general quality, construction, and difficulty level.
| |
| | |
| The inspectors assessed the level of examination material duplication from week-to-week during the current year operating test and written examinations. The inspectors reviewed the methodology for developing the examinations, including the LORT program two-year sample plan, probabilistic risk assessment insights, previously identified operator performance deficiencies, and plant modifications.
| |
| | |
| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.4 Licensee Administration of Requalification Examinations===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors observed the administration of a requalification operating test to assess the licensee's effectiveness in conducting the test to ensure compliance with 10 CFR 55.59(c)(4), "Evaluation." The inspectors evaluated the performance of one crew in parallel with the facility evaluators during one dynamic simulator scenario and evaluated various licensed crew members concurrently with facility evaluators during the administration of several JPMs. The inspectors assessed the facility evaluators' ability to determine adequate crew and individual performance using objective, measurable standards. The inspectors observed the training staff personnel administer the operating test, including conducting pre-examination briefings, evaluations of operator performance, and individual and crew evaluations upon completion of the operating test. The inspectors evaluated the ability of the simulator to support the examinations. A specific evaluation of simulator performance was conducted and documented under Section 1R11.9 of this report.

| |
| | |
| ===.5 Examination Security===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors observed and reviewed the licensee's overall licensed operator requalification examination security program related to examination physical security (e.g., access restrictions and simulator considerations) and integrity (e.g., predictability and bias) to verify compliance with 10 CFR 55.49, "Integrity of examinations and tests." The inspectors also reviewed the facility licensee's examination security procedure, any corrective actions related to past or present examination security problems at the facility, and the implementation of security and integrity measures (e.g., security agreements, sampling criteria, bank use, and test item repetition) throughout the examination process.
| |
| | |
| ====b. Findings====
| |
| There was one issue associated with examination security identified by the licensee during the administration of JPMs during the sixth week of administration of the 2007 annual operating test. On October 31, 2007, an individual who had just completed a simulator JPM was escorted back to the waiting room area and dropped off. However, there was no examination sequesterer in the waiting room area to ensure that there was no examination compromise with individuals in the room who had not been administered the JPM. Within two minutes, the licensee identified the potential for an examination compromise. The licensee determined that the individual who had just been administered the JPM did not communicate any exam-related information to any other individuals who had not been administered the JPM. As part of its corrective actions, the licensee held a training department standdown with the members of the examination team. The licensee replaced the JPM in question for the remaining individuals to be tested. The issue was documented in the corrective action program as CAP 01115710. The NRC was appropriately notified of the issue. The issue was reviewed and assessed for a possible violation of 10 CFR 55.49, "Integrity of examinations and tests." With the actions taken, it was determined that no actual examination compromise had occurred. The issue was not subject to enforcement action in accordance with NRC enforcement policy.
| |
| | |
| ===.6 Licensee Training Feedback System===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors assessed the methods and effectiveness of the licensee's processes for revising and maintaining its LORT program up-to-date, including the use of feedback from plant events and industry experience information. The inspectors reviewed the licensee's quality assurance oversight activities, including licensee training department self-assessment reports. The inspectors evaluated the licensee's ability to assess the effectiveness of its LORT program and its ability to implement appropriate corrective 14 Enclosure actions. This evaluation was performed to verify compliance with 10 CFR 55.59(c) "Requalification program requirements", and the licensee's SAT program.
| |
| | |
| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.7 Licensee Remedial Training Program===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors assessed the adequacy and effectiveness of the remedial training conducted since the previous biennial requalification examinations and the training from the current examination cycle to ensure that they addressed weaknesses in licensed operator or crew performance identified during training and plant operations. The inspectors reviewed remedial training procedures and individual remedial training plans. This evaluation was performed in accordance with 10 CFR 55.59(c), "Requalification program requirements," and with respect to the licensee's SAT program.
| |
| | |
| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.8 Conformance with Operator License Conditions===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors reviewed the facility and individual operator licensees' conformance with the requirements of 10 CFR Part 55. The inspectors reviewed the facility licensee's program for maintaining active operator licenses and to assess compliance with 10 CFR 55.53(e) and (f). The inspectors reviewed the procedural guidance and the process for tracking on-shift hours for licensed operators and which control room positions were granted watch-standing credit for maintaining active operator licenses.
| |
| | |
| The inspectors reviewed the facility licensee's LORT program to assess compliance with the requalification program requirements as described by 10 CFR 55.59(c). Additionally, medical records for seven licensed operators were reviewed for compliance with 10 CFR 55.53(i).
| |
| | |
| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.9 Conformance with Simulator Requirements===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors assessed the adequacy of the licensee's simulation facility (simulator) for use in operator licensing examinations and for satisfying experience requirements as prescribed in 10 CFR 55.46, "Simulation facilities." The inspectors also reviewed a sample of simulator performance test records (i.e., transient tests, malfunction tests, and core performance tests), simulator discrepancies, and the process for ensuring 15 Enclosure continued assurance of simulator fidelity in accordance with 10 CFR 55.46. The inspectors reviewed and evaluated the discrepancy process to ensure that simulator fidelity was maintained. Open simulator discrepancies were reviewed for importance relative to the impact on 10 CFR 55.45 and 55.59 operator actions, as well as on nuclear and thermal hydraulic operating characteristics. The inspectors interviewed the licensee's simulator staff about the configuration control process and completed the Inspection Procedure 71111.11, Appendix C checklist, to evaluate whether the licensee's plant-referenced simulator was operating adequately as required by 10 CFR 55.46(c) and (d).

| ===.10 Annual Operating Test Results===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors reviewed the overall pass/fail results of the annual JPM operating tests, and the annual simulator operating tests (required to be given per 10 CFR 55.59(a)(2)) administered by the licensee during 2007. The overall results were compared with the SDP in accordance with IMC 0609, Appendix I, "Operator Requalification Human Performance Significance Determination Process (SDP)," dated August 22, 2005. The year 2007 was the first year of the licensee's 24-month training program; therefore, no written examination was administered in 2007. This represented one sample.

| |
| The inspectors reviewed risk assessments for planned and emergent maintenance activities during the specified work weeks. During these reviews, the inspectors compared the licensee's risk management actions to those actions specified in the licensee's procedures for the assessment and management of risk associated with maintenance activities. The inspectors assessed whether evaluation, planning, control, and performance of the work were done in a manner to reduce the risk and minimize the duration, where practical, and whether contingency plans were in place where appropriate.
| |
| | |
| The inspectors used the licensee's daily configuration risk assessment records, observations of shift turnover meetings and observations of daily plant status meetings to determine whether the equipment configurations were properly listed. The inspectors also verified that protected equipment was identified and controlled as appropriate and that significant aspects of plant risk were communicated to the necessary personnel.
| |

| ====a. Inspection Scope====
| |
| The inspectors reviewed CAP 01098680, its associated operability evaluation (OPR), apparent cause evaluation (ACE), and past operability evaluation in the licensee's corrective action program. The inspectors reviewed design basis information, the FSAR, TS requirements, and licensee procedures to determine the technical adequacy of the operability evaluations. The inspectors also reviewed the licensee's implementation of select sections of the American Society of Mechanical Engineers (ASME) Operational Maintenance (OM) Code, 1995 Addenda, to evaluate whether requirements were met and the appropriate actions were taken in accordance with the Code. In addition, the inspectors determined whether compensatory measures were implemented, as required.
| |
| | |
| The inspectors assessed whether system operability was properly justified and that the system remained available, such that no unrecognized increase in risk occurred.
| |

| This review constituted one sample.
| |
| | |
| ====b. Findings====
| |
| | |
| =====Introduction:=====
| |
| A self-revealing finding with no associated violation of regulatory requirements was identified for an inadequate operability evaluation issued on June 28, 2007, associated with safety-related SW pump P-32C. Specifically, P-32C failed its inservice test (IST) on high vibrations after only 6.5 hours of operation, but the June 2007 operability evaluation had concluded that the pump would remain operable and not reach the IST out-of-service limit until 120 hours of continuous operation. The licensee's non-conservative decision-making and use of a non-conservative prediction model led to the incorrect conclusion of operability of the P-32C pump. Had the licensee used an appropriate prediction model, reflective of a degraded/degrading pump, the OPR would have concluded the pump was inoperable.
| |
| | |
| =====Description:=====
| |
| Service water pump P-32C was placed on increased IST frequency after trending into the IST Alert Range in May 2007. On June 24, 2007, during the next performance of increased frequency testing, P-32C vibration was recorded at 0.3051 inches per second (ips) compared to the Required Action limit of > 0.327 ips. Because this vibration measurements approaching this out-of-service limit of the pump, 17 Enclosure OPR 01098680 was performed to: review the vibration trend and determine the additional run time until the IST out-of-service limit might be reached, compare this duration to the mission time of the P-32C pump, and determine if any additional compensatory measures were required to be taken.
| |
| | |
| Licensee engineers utilized vibration analysis software to predict the point at which P-32C would exceed the 0.327 ips out-of-service limit. Based on the licensee's assumption that the degrading vibration trend was due to normal bearing wear, the trend projection grossly overestimated the pump's remaining acceptable run time. Specifically, the model predicted that an additional 120 hours, or five days, of continuous operation could be achieved before reaching 0.327 ips. On August 8, 2007, however, the next increased frequency IST was performed on P-32C and a vibration level of 0.4055 ips was observed. Because this value exceeded the 0.327 ips IST out-of-service limit, P-32C was declared inoperable and the appropriate TS action statement was entered. The pump was subsequently rebuilt and returned to service on August 11 after 71 hours of unavailability. The inspectors reviewed ACE 01098680-02. The purpose of this ACE was to determine the cause of the unexpected step change in vibrations and to determine why vibrations exceeded the IST out-of-service limit in only 6.5 hours vice the 120 hours of predicted run time. From the review, the inspectors concluded that the licensee applied non-conservative assumptions to the vibration trend projection when it failed to factor in vibration amplifying resonance effects, or any additional conservative margin for uncertainty. The inspectors identified another example of the licensee's non-conservative decision-making. Specifically, the licensee's OPR did not conservatively address the 30-day design basis mission time of the SW pumps when the IST out-of-service limit was predicted to be reached in less than the full 30-day mission time. Section ISTB 6.2.2 of the Code states: "If the measured test parameter values fall within the required action range, the pump shall be declared inoperable until either the cause of the deviation has been determined and the condition is corrected, or an analysis of the pump is performed and new reference values are established in accordance with paragraph ISTB 4.6." of the Code. The licensee did not declare P-32C inoperable when it was identified that the vibration parameters would exceed the required action limit within the 30-day mission time of the pump, nor were new baseline values established in accordance with the Code.
| |
| | |
| =====Analysis:=====
| |
| The inspectors determined that the failure to use appropriate, conservative, calculation assumptions in the trend projection to justify the basis for the continued operability of a safety-related-pump, is a performance deficiency and a finding. The finding is more than minor because it could reasonably be viewed as a precursor to a significant event. Using IMC 0609, "Significance Determination Process," dated January 10, 2008, the inspectors determined that the finding is of very low safety significance (Green) because the finding did not involve a design deficiency, there was no actual loss of safety function, no single train loss of safety function for greater than the TS-allowed outage time, and no risk due to external events.
| |
| | |
| 18 Enclosure Additionally, the inspectors determined that the finding had a cross-cutting aspect in the area of human performance. Specifically, the licensee failed to use conservative assumptions in making decisions affecting the operability of safety-related components (H.1(b)).
| |
| | |
| =====Enforcement:=====
| |
| The failure to perform an adequate operability evaluation, which was based upon non-conservative decision-making and a non-conservative trend projection, was not a violation of regulatory requirements although a performance deficiency existed. Therefore, this issue is considered a finding of very low safety significance (FIN 05000266/2007005-02; 05000301/2007005-02).
| |
| | |
| The licensee included this finding in its corrective action program as CAP 01119241 and has actions planned to perform an ACE to address the use of IST trend data in OPRs.
| |

| ===.2 Operability Evaluations for the Unit 2 TDAFW Pump 2P-29 Following Overhaul===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors reviewed selected immediate operability evaluations and operability evaluations associated with issues entered into the licensee's corrective action program. The inspectors reviewed design basis information, the FSAR, TS requirements, and licensee procedures to determine the technical adequacy of the operability evaluations. In addition, the inspectors determined whether compensatory measures were implemented, as required. The inspectors assessed whether system operability was properly justified and that the system remained available, such that no unrecognized increase in risk occurred.
| |
| | |
| The reviews of the following OPRs constituted six samples:

| ====b. Findings====
| |
| | |
| =====Introduction:=====
| |
| The inspectors identified a finding of very low safety significance (Green) and an associated Non-Cited Violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the failure to adequately assess operability of the Unit 2 TDAFW pump in accordance with plant procedures. The inspectors identified that the licensee failed to implement procedural requirements regarding the immediate assessment of operability on September 24 and September 27, 2007, for the 19 Enclosure increased water ingress into the turbine outboard bearing housing for the pump following maintenance.
| |
| | |
| =====Description:=====
| |
| On September 24, 2007, following the overhaul of the 2P-29 TDAFW pump, an oil sample was taken from the outboard bearing housing, after a four-hour run. CAP 01112660 was written, which documented that an estimated water volume in the oil sample based on visual indication was approximately 1,000 to 1,500 parts per million (ppm) for the four-hour run. The CAP description concluded that this was an expected condition. A second shorter pump run was performed and the water content in the oil was visually estimated to be approximately 100 ppm of water. The licensee rationalized that the initial water content was expected and the condition report was closed with no further actions taken. However, the inspectors identified that neither the operations nor engineering staff questioned why a visual estimate for indication of water in the oil would have produced five times the amount of water in the oil immediately following the overhaul, as compared to the first oil sample taken in June 2007 following a November 2006 overhaul, which showed 300 ppm water in the oil. The June 2007 outboard oil sample for the 2P-29 turbine was the first time the oil was sampled since the November 2006 overhaul and the first time water ingress was noted in the turbine outboard bearing. On September 27, CAP 01113318 was written and documented that the outboard oil sample from the first four-hour run, analyzed by a laboratory, contained 20,040 ppm of water (approximately two percent by volume). The CAP description also noted that the number was not consistent with the visual estimate from September 24 of 1,000 to 1,500 ppm. However, the CAP dismissed the results, based on conjecture, concluding that the 20,040 ppm results were false readings due to a laboratory error or an accidental capture of water droplets during the sampling process. The CAP concluded that "the indicated levels of water in the IT-09A sample are errant." The immediate operability assessment concluded that based on the information provided in the description section there were no operability concerns. In addition, the assessment discussed that the pump was tested satisfactorily, with no abnormal indications observed during the run. The inspectors, as well as the licensee personnel performing the causal evaluation for this issue, concluded that the increased water first observed on September 24 should not have been discounted and was discounted due to confirmational biases, resulting in nonconservative assumptions in the evaluation of this condition. The inspectors reviewed the licensee's procedure for operability, Fleet Procedure FP OP-OL-01, "Operability Determination." The procedure required a determination if a condition existed that could call into question the ability of a structure, system, or component (SSC) to perform its specified safety function. An example of such a condition was an item which met the definition of a degraded condition. A degraded condition, as defined in the fleet procedure, was a condition where there had been a noticeable change in parameters that were precursors to failure. The attachment guidance for immediate operability review also highlighted questions for performing operability determinations, which included the following: "Could the capability of a SSC to prevent or mitigate consequences of an accident as postulated in the Final Safety Analysis Report be reduced?" The guidance suggested that an OPR should be requested if additional engineering evaluation and justification was needed to answer those questions. Finally, the inspectors noted that the guidelines for operability recommendations included guidance to evaluate trend data to identify a deteriorating 20 Enclosure condition and to utilize an OPR to predict the point when a SSC may become inoperable. The inspectors concluded the licensee had not adequately implemented the procedures for operability determinations for the September 24 and 27 CAPs. The licensee had not assessed the parameter of a significant increase in the ingress of water following a maintenance overhaul, as compared to the last maintenance overhaul.
| |
| | |
| On November 1, 2007, approximately 5 weeks after the maintenance overhaul, the licensee ran 2P-29 for about two hours and then sampled the oil. The outboard oil sample had 29,515 ppm of water in the oil. The licensee declared the pump inoperable and revised the July 2007 operability evaluation for the original water ingress issue in June.
| |
| | |
| On November 3, the licensee issued Revision 2 to OPR1098358 and the pump was determined to be capable of performing the design functions for the design basis mission time of eight hours. On November 4, Revision 3 to OPR1098358 was issued to specify a compensatory measure of testing the pump every 72 hours for an eight-hour duration. The subsequent pump runs continued to show high levels of water in the outboard bearing oil. The inspectors identified that Revisions 2 and 3 utilized data from 2P-29 on water ingress rates prior to the September 2007 turbine overhaul. These values were not applicable to the current condition, because the September maintenance had created a new and greater water ingress problem. Revision 4 to OPR1098358, issued on November 7, was a rewrite of the OPR utilizing current oil analysis data from after the overhaul. In addition, the licensee hypothesized, as part of the operability discussion, that differences in water concentrations in the oil seen since November 1 were likely the result of a change in sampling techniques. However, the inspectors noted that these theories were refuted by visual observation and comparison of the quarantined oil samples taken since November 1. Further testing of the previous oil samples also refuted the sampling technique theories. In addition, the inspectors noted that the licensee did not have any established procedural controls or work instructions for mixing of the samples and splitting of the samples to ensure quality control. The licensee initiated a condition report and took immediate corrective actions to address this latter issue. Revision 5 to the OPR was issued on November 10 and contained additional discussion on the potential for an unexpected increase in steam leakage, and additional information related to the sampling technique and testing duration.
| |
| | |
| The inspectors noted that for all the revisions, the OPR demonstrated that the TDAFW pump would have performed the required safety functions for the eight-hour mission time of the FSAR Chapter 14 design basis accidents. However, the inspectors pointed out to the licensee that the OPR did not address all the safety functions required to be performed by the TDAFW pump, which at Point Beach included several fire-related scenarios. The licensee subsequently initiated a CAP for this issue. Additional information regarding the issues associated with the 2P-29 TDAFW pump is documented in Section 4OA5.2 of this report.
| |
| | |
| =====Analysis:=====
| |
| The inspectors determined that the failure to adequately perform an operability determination was a performance deficiency and a finding that warranted a significance evaluation. Using IMC 0612, "Power Reactor Inspection Reports," Appendix B, "Issue Screening," dated September 20, 2007, the inspectors determined that the finding is more than minor because, if left uncorrected, the failure to properly assess operability 21 Enclosure would result in the TDAFW pump being degraded and potentially inoperable, exceeding the allowed outage time in accordance with TSs. Using IMC 0609, Appendix A, "Determining the Significance of Reactor Inspection Findings for At-Power Situations," dated January 10, 2008, the inspectors determined the finding may have resulted in a late determination of an actual loss of safety function of a system or train of equipment. The risk assessment for the potential loss of safety function is attributed to the performance deficiencies associated with inadequate maintenance discussed in Section 4OA5.2.b.2 as URI 5000266/2007005-07. This did not cause the loss of safety function for greater than the allowed outage time. Therefore, the finding is considered to be of very low safety significance (Green). Additionally, the inspectors determined that the finding has a cross-cutting aspect in the area of human performance. Specifically, the licensee failed to use conservative assumptions in decision-making affecting operability of safety-related equipment (H.1(b)).
| |
| | |
| =====Enforcement:=====
| |
| 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," requires, in part, that activities affecting quality be prescribed and accomplished by procedures appropriate to the circumstances. The licensee failed to implement the operability determination procedure FP-OP-OL-01, "Operability Determination." The procedure required, in part, that the licensee assess the capability of a SSC to prevent or mitigate consequences of an accident as postulated in the FSAR. Contrary to this, the licensee failed to adequately assess the operability of the turbine outboard bearing for the Unit 2 TDAFW pump following increased water intrusion during post-maintenance testing on September 24, 2007, and later corroborated by oil analyses on September 27. Because this finding was of very low safety significance (Green) and because it was entered into the licensee's corrective action program (as CAP 01115748), this violation is being treated as a Non-Cited Violation, consistent with Section VI.A of the NRC Enforcement Policy (NCV 05000301/2007005-03). The licensee took immediate corrective actions to address the issue, and at the end of the inspection period the licensee continued to evaluate the causes associated with this finding.

| ===.3 Operability Evaluations===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors reviewed selected operability evaluations associated with issues entered into the licensee's corrective action program. The inspectors reviewed design basis information, the FSAR, TS requirements, and licensee procedures to determine the technical adequacy of the operability evaluations. In addition, the inspectors determined whether compensatory measures were implemented, as required. The inspectors assessed whether system operability was properly justified and that the system remained available, such that no unrecognized increase in risk occurred.

| ===.1 Inspection Planning===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors reviewed the FSAR to identify applicable radiation monitors associated with measuring transient high and very high radiation areas, including those intended for remote emergency assessment. The inspectors identified the types of portable radiation detection instrumentation used for job coverage of high radiation area work, including instruments used for underwater surveys, portable and fixed area radiation monitors used to provide radiological information in various plant areas, and continuous air monitors used to assess airborne radiological conditions and, consequently, work areas with the potential for workers to receive a 50 millirem or greater committed effective dose equivalent (CEDE). Whole body counters used to monitor for internal exposure and those radiation detection instruments utilized to conduct surveys for the release of personnel and equipment from the radiologically controlled area (RCA), including contamination monitors and portal monitors, were also identified.
| |
| | |
| 26 Enclosure These reviews represented two inspection samples.
| |
| | |
| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.2 Walkdowns of Radiation Monitoring Instrumentation===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors conducted walkdowns of selected area radiation monitors (ARMs) in the Unit 1 and Unit 2 auxiliary building to determine if these monitors were located and provided measurement capability as described in the FSAR and were optimally positioned relative to the potential sources of radiation they were intended to monitor. Walkdowns were conducted of those areas where portable survey instruments were source checked and maintained for radiation protection (RP) staff use to determine if those instruments designated "ready for use" were sufficient in number to support the RP program, had current calibration stickers, were operable, and were in adequate physical condition. Also, the inspectors observed the licensee's portable survey instrument calibration units and the radiation sources used for operability checks of various radiation measuring instruments to assess their material condition and discussed their use with RP staff to determine if they were used appropriately. Additionally, the inspectors observed the use of the instrument calibration units, discussed with the staff calibrator output validation methods, and compared calibrator exposed readings with calculated/expected values. The inspectors evaluated compliance with licensee procedures while RP personnel demonstrated the methods for performing source checks of portable survey instruments and source checks of personnel contamination and portal monitors located at the egress to the RCA and the plant protected area. These reviews represented one partial inspection sample, which combined with Section 2OS3.3 constituted one sample.

| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.3 Calibration and Testing of Radiation Monitoring Instrumentation===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors selectively reviewed radiological instrumentation associated with monitoring transient high and/or very high radiation areas, instruments used for remote emergency assessment, and radiation monitors used to identify personnel contamination and for assessment of internal exposures to verify that the instruments had been calibrated as required by the licensee's procedures, consistent with industry and regulatory standards. The inspectors also reviewed alarm setpoints for selected ARMs, for personnel contamination monitors and for portal (egress) monitors to verify that they were established consistent with the FSAR or TSs, as applicable, and were consistent with industry practices and regulatory guidance. Specifically, the inspectors reviewed calibration procedures and the most recent calibration records for the following radiation monitoring instrumentation and calibration equipment:
| |
| * Unit 1 and Unit 2 Containment High Range (Accident) Radiation Monitors;
| |
| * Unit 1 and Unit 2 Charging Pump Room Low and High Range ARMs;
| |
| * Unit 1 and Unit 2 Seal Table ARMs;
| |
| * Unit 1 and Unit 2 Post-Accident Sample Line Monitors;
| |
| * Common Unit Safety Injection Pump Room Low and High Range ARMs;
| |
| * Portable Gamma and Neutron Survey Instruments (Model AMP-100 and ASP-1);
| |
| * Portable Air Sampler (Model AMS-4);
| |
| * Portal (Gamma) Monitors Used at RCA and Protected Area Egresses;
| |
| * Personnel Contamination Monitors Used at RCA Egress;
| |
| * Two Instrument Calibrators (and the associated instruments used to measure calibrator output); and
| |
| * Whole Body Counter. The inspectors determined what actions were taken when, during calibration or source checks, an instrument was found significantly out of calibration or exceeded as-found acceptance criteria. Should that occur, the inspectors verified that the licensee's actions would include a determination of the instruments previous uses and the possible consequences of that use since the prior calibration. The inspectors also reviewed the results of the licensee's most recent 10 CFR Part 61 source term (radionuclide mix) evaluation to determine if instrument/monitor calibration and check sources were representative of the plant source term. Given that source term, the inspectors reviewed the licensee's method for internal dose assessment to determine if difficult to detect nuclides were scaled into whole body count dose determinations.
| |
| | |
| These reviews represented one partial inspection sample, which combined with Section 2OS3.2 constituted one sample.
| |
| | |
| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.4 Problem Identification and Resolution===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors reviewed corrective action documents and any special reports that involved personnel contamination monitor alarms due to personnel internal exposures to determine whether identified problems were entered into the corrective action program for resolution. Licensee self-assessments, audits, and corrective action documents were also reviewed to determine if problems with radiological instrumentation or with self-contained breathing apparatus (SCBA) were identified, characterized, prioritized, and resolved effectively using the corrective action program. While no internal exposure with a CEDE greater than 50 millirem occurred since the last inspection in this area, the inspectors reviewed the licensee's methodology for internal dose assessment. The inspectors reviewed corrective action program reports related to exposure-significant radiological incidents that involved radiation monitoring instrument deficiencies since the last inspection in this area, as applicable. Members of the RP staff were interviewed and corrective action documents were reviewed to determine 28 Enclosure whether follow-up activities were being conducted in an effective and timely manner commensurate with their importance to safety and risk based on the following:
| |
| * Initial problem identification, characterization, and tracking;
| |
| * Disposition of operability/reportability issues;
| |
| * Evaluation of safety significance/risk and priority for resolution;
| |
| * Identification of repetitive problems;
| |
| * Identification of contributing causes;
| |
| * Resolution of Non-Cited Violations tracked in the corrective action program; and
| |
| * Identification and implementation of effective corrective actions. The inspectors determined if the licensee's self-assessment and audit activities completed for the approximate two-year period that preceded the inspection were identifying and addressing repetitive deficiencies or significant individual deficiencies in problem identification and resolution, as applicable. These reviews represented three inspection samples.

| | |
| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.5 RP Technician Instrument Use===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors selectively determined whether calibrations for those survey instruments used to perform job coverage surveys and for those currently designated for use had not lapsed. The inspectors reviewed instrument issue logs for selected dates in 2007 to determine if response checks of portable survey instruments and checks of instruments used for unconditional release of materials and workers from the RCA were completed prior to instrument use, or daily, as required by the licensee's procedure. The inspectors also discussed instrument calibration methods and source response check practices with radiation protection staff and observed staff demonstrate instrument source checks. These reviews represented one inspection sample.
| |
| | |
| ====b. Findings====
| |
| No findings of significance were identified.
| |
| | |
| ===.6 SCBA Maintenance/Inspection and Emergency Response Staff Qualifications===
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors reviewed aspects of the licensee's respiratory protection program for compliance with the requirements of Subpart H of 10 CFR Part 20 and to determine if SCBA equipment was properly inspected, maintained, and ready for emergency use. The inspectors reviewed records of inspection and functional tests performed in 2006 and 2007 for all SCBAs staged in the plant to support both the licensee's fire brigade and emergency response organization, as provided in the Point Beach Emergency Plan.
| |
| | |
| 29 Enclosure The inspectors evaluated the licensee's capabilities for refilling and transporting SCBA air bottles to and from the control room during emergency conditions. The inspectors determined if control room staff designated for the active on shift duty roster were trained, respirator fit-tested, and medically certified to use SCBAs. Additionally, the inspectors reviewed SCBA qualification records for the licensee's radiological emergency teams, including the radiation protection, chemistry, and maintenance staffs, to determine if a sufficient number of staff were qualified to fulfill emergency response positions consistent with the Emergency Plan and the requirements of 10 CFR 50.47. The inspectors also reviewed the respiratory protection training lesson plan to assess its overall adequacy relative to Subpart H of 10 CFR Part 20. The inspectors walked down SCBA equipment maintained in the control room, the Operations Support Center, various areas of the turbine building and in the warehouse fire brigade ready rooms, as well as spare SCBA air bottle stations. During these walkdowns, the inspectors examined numerous SCBA units to assess their material condition and to determine if air bottle hydrostatic tests were current and if bottles were pressurized to meet procedural requirements. The inspectors reviewed records of SCBA equipment inspection and functional testing, including results of the most recent regulator flow tests for all SCBA units maintained at the site. Additionally, the inspectors observed members of the licensee's operations and RP staffs demonstrate the methods used to conduct the inspections and functional tests to determine if these activities were performed consistent with procedure and the equipment manufacturer's recommendations. The inspectors also evaluated through record review and observations if the required air cylinder hydrostatic testing was documented and current, if the Department of Transportation required retest air cylinder markings were in place for numerous randomly selected SCBA units and spare air bottles, and if air quality for the compressor used to fill SCBA air bottles was routinely tested to verify Grade-D quality. The inspectors also reviewed the qualification documentation (training certificate) issued by the SCBA manufacturer to an individual contracted by the licensee to perform maintenance/repair of SCBA vital components. Pressure regulator test/repair records for 2007 for all SCBA units designated for emergency use were reviewed to determine if the equipment was adequately maintained consistent with the manufacturer's maintenance procedure. These reviews represented two inspection samples.

| The inspectors' review nominally considered July 2007 through December 2007, although some examples expanded beyond those dates. The reviews also included issues documented outside the normal corrective action program in major equipment problem lists, repetitive and/or rework maintenance lists, departmental problem/challenges lists, system health reports, quality assurance audit/surveillance reports, self-assessment reports, and Maintenance Rule assessments. The inspectors compared and contrasted their results with the results contained in the licensee's corrective action program trending reports. Corrective actions associated with a sample of the issues identified in the licensee's trending reports were reviewed for adequacy. This semi-annual trend review by the inspectors constituted one inspection.

| ===.1 TS-Required Shutdown Due to High Unit 2 Refueling Water Storage Tank Temperature===
| |
| | |
| ====a. Inspection Scope====
| |
| Through record reviews and discussion with plant staff, the inspectors assessed the circumstances of a TS-required shutdown initiated on September 18, 2007. Although the licensee took immediate corrective actions to de-energize the submersion heaters and cool the RWST by forced recirculation, the temperature could not be restored to acceptable limits before the eight-hour TS action statement expired. As a result, Unit 2 commenced a TS-required shutdown that was later averted, while at approximately 20 percent reactor power, when the RWST temperature was restored to within acceptable limits. The inspection scope included a review of the events leading up to the shutdown initiation.
| |
| | |
| ====b. Findings====
| |
| | |
| =====Introduction:=====
| |
| A self-revealing finding of very low safety significance (Green) and an associated Non-Cited Violation (NCV) of 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," was identified for the failure to allow operators to properly set the thermostat of the Unit 2 RWST heaters, and to ensure that the RWST was recirculated frequently enough for the temperature indicator to accurately measure bulk temperature.
| |
| | |
| =====Description:=====
| |
| On September 18, 2007, during the performance of TS-required surveillance SR 3.5.4.1, the Unit 2 RWST was found to be at 105 °F. The TS maximum allowable limit was 100 °F (97 °F parametric). Because RWST temperature could not be restored within the allowed eight hours, operators commenced a shutdown of Unit 2. At 20 percent power, the temperature was returned to within acceptable limits and the operators began to raise reactor power to 100 percent. The cause of the elevated temperature was found to be the incorrectly set RWST heater thermostat. It was identified that on August 30, the controlling thermostat for the RWST heaters was incorrectly set to 95 °F vice 50
| |
| °F as required by procedure. For the 18 days between August 30 and September 18, the bulk water temperature increased to 105 °F through natural circulation. During this period, daily temperature readings of the RWST only showed an increase from 75 °F to 85 °F. This disparity occurred due to stratification caused by the location of the single temperature indicator relative to the heaters inside the tank. Because the RWST temperature indicator is located 2 feet from the bottom of the 70 foot tall tank, and the heaters are located 4.5 feet above the indicator, stratification caused the temperature indicator to remain in a layer of colder water. It was not until September 18, that the RWST temperature was found to be at 105 °F, after four hours of being on forced recirculation.
| |
| | |
| The inspectors reviewed procedure PC 49, part 4, Revision 19, which was used for setting the thermostat on the RWSTs to 50 °F. This task was performed once a year during cold weather preparations to ensure that the RWST remained within the required temperature range of 40 to 100 °F. Through this review, the inspectors concluded that a lack of sufficient detail existed for the critical step of setting the thermostat, which directly affected the operability of the safety-related RWST. Specifically, the lack of procedural 36 Enclosure detail contributed to the operator's reliance upon an unapproved operator aid in the field; in this case, a black marking that was believed by the operator to indicate the desired thermostat setting.
| |
| | |
| The inspectors also reviewed procedure PC 25, Revision 23, which was used to recirculate and purify the RWST. This task was performed to keep the RWST contents in a homogeneous mixture to prevent stratification. Through this review, the inspectors concluded that the frequency of RWST recirculation, which was performed monthly, was inadequate to ensure that the temperature indicator accurately read bulk tank temperature to satisfy the TS operability requirements, while the heaters were energized.
| |
| | |
| =====Analysis:=====
| |
| The inspectors determined that the failure to have adequate procedures in place to ensure the operability of the safety related RWST is a performance deficiency and a finding. The finding is more than minor in accordance with IMC 0612, "Power Reactor Inspection Reports," Appendix B, "Issue Screening," dated September 20, 2007, because it is associated with the procedural quality and human performance attributes of the Mitigating Systems Cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using IMC 0609, "Significance Determination Process", dated January 10, 2008, the inspectors determined that the finding is of very low safety significance (Green) because the finding did not involve a design deficiency, there was no actual loss of safety function, no single train loss of safety function for greater than the TS allowed outage time, and no risk due to external events. The inspectors also determined that the finding had a cross-cutting aspect in the area of human performance. Specifically, human error prevention techniques were not utilized prior to and during the thermostat setting task and personnel proceeded in the face of uncertainty and unexpected circumstances (H.4(a)).
| |
| | |
| =====Enforcement:=====
| |
| 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," requires, in part, that activities affecting quality be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures and drawings. Contrary to this, the licensee's procedure PC 49, part 4, used for setting the RWST heater thermostat, did not have adequate instructions for correctly setting the thermostat. Further, the monthly recirculation of the RWST, specified in procedure PC-25, was not appropriate to ensure that the TS-required temperature readings were valid in their indication of bulk tank temperature while heaters were energized. Because of the very low safety significance of this finding and because the finding was entered into the licensee's corrective action program (CAP 01111841), the violation is being treated as an NCV, consistent with Section VI.A.1 of NRC Enforcement Policy (NCV 05000266/2007005-04; 05000301/2007005-04). The licensee entered the event into its corrective unit action program, took corrective actions to increase the frequency of the Unit 1 and Unit 2 RWST recirculation to once every seven days until the heaters were no longer needed due to seasonal temperature increases, and conducted a root cause evaluation.

| Failure to Update Final Safety Analysis Report with Reactor Head Drop Analysis and Obtain NRC Approval The inspectors evaluated the licensee's corrective action program responses to the January 29, 2007, Notice of Violation associated with the NRC Special Inspection Report 05000266/2006011; 05000301/2006011, for issues in the spring of 2005, regarding a 1982 reactor vessel head drop analysis. The inspectors reviewed the corrective actions the licensee described in its correspondence dated December 19, 2006, entitled, "Response to an Apparent Violation in Inspection Report05000266/2006011; 05000301/2006011; EA-06-274." The inspectors validated the following corrective actions were complete: incorporation of the Reactor Vessel Head Drop Analyses into the FSAR; revision of the Technical Requirements Manual Section 3.9.4; revision of plant procedures, including maintenance, outage, and operations procedures and checklists; development of a licensing basis policy and training for plant staff on that policy; development and implementation of a continuing training module for plant engineers; licensee evaluation and validation of commitments contained in an October 1996 NRC, "Request for Information Pursuant to 10 CFR 50.54(f) Regarding Adequacy and Availability of Design Basis Information," with corresponding corrective actions for identified deficiencies; and development of a procedure writer/reviewer certification matrix with a job familiarization guide which addressed how to search the site's regulatory information system. The review by the inspectors constituted one inspection procedure sample.

| |
| Inadequate Post-Maintenance Testing (PMT) of the Turbine-Driven Auxiliary Feedwater Pumps Following Major Maintenance
| |
| | |
| =====Introduction:=====
| |
| The inspectors identified a finding of very low safety significance (Green) and an associated Non-Cited Violation of 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the licensee's failure to conduct adequate PMT of the Unit 1 1P-29 TDAFW pump following a ten-year overhaul of the turbine in May 2007. Specifically, the ten-year overhaul maintenance included bearing replacement, but, the PMT did not run the TDAFW pump long enough for bearing temperature to stabilize. The appropriate PMT would have detected that the bearing temperatures were rising and required evaluation prior to declaring the TDAFW operable.
| |
| | |
| =====Description:=====
| |
| The licensee completed an overhaul of the Unit 1 TDAFW turbine and the associated PMT on May 6, 2007, declaring the TDAFW pump operable following completion of quarterly IST procedure IT-8A. The PMT requirements for the overhaul were listed in the maintenance overhaul procedure, RMP 9044-1. The IST procedure had no specific requirements to monitor bearing temperatures for stabilization other than to perform the IST, which recorded bearing temperature data. The procedure did have a temperature limit to place the pump in the alert range and conduct an engineering evaluation when the turbine outboard bearing exceeded 225 °F, and to remove the pump from service and declare the pump inoperable when the same bearing exceeded 250 °F. However, as part of the PMT for the ten-year overhaul, there was no 38 Enclosure requirement in either the work order, maintenance procedure or the IST procedure, to ensure bearing temperatures were stabilized. For testing on May 1, the inspectors noted that the outboard bearing temperature reached 247 °F, as indicated on the chart recorders. During the PMT on May 6, some licensee personnel noted the turbine outboard bearing rising, but indicated the temperatures was "stabilizing." However, the licensee did not wait for temperature stabilization and secured the Unit 1 TDAFW pump. The inspectors' review of chart recorders revealed that the outboard bearing temperature was at 238 °F and still rising. The licensee had declared the TDAFW pump operable with no PMT assessment of the outboard bearing temperature trend and no engineering analysis or evaluation of the changes in outboard bearing temperature from prior to the overhaul.
| |
| | |
| During the Unit 1 TDAFW pump quarterly IST procedure IT-8A performance on June 9, turbine outboard bearing temperature exceeded 225 °F. The turbine outboard bearing temperature was at 233
| |
| °F and still rising when the pump was secured after the test was completed. In this case, a CAP was written and a follow-up test was completed on June 12, with the goal to attain bearing temperature stabilization. The test was stopped at around 249.5 °F, prior to bearing temperature stabilization, and the 250
| |
| °F limit to secure the pump. The pump was declared inoperable and the plant was subsequently shutdown to repair the TDAFW turbine.
| |
| | |
| The licensee's root cause evaluation indicated the turbine was improperly assembled during the overhaul in May 2007. In addition, the inspectors determined that changes to procedure NP 10.2.7, "Post Maintenance/Return to Service Testing," did not occur when a change in the ASME OM Code in 1998 resulted in removing stabilization criteria from the normal ISTs for safety-related equipment. Specifically, the procedure allowed credit to be taken for ISTs; however, the procedure did not alert personnel that ISTs no longer required temperature stabilization. Procedure NP 10.2.7, did specify that licensee personnel review the PMT matrix for maintenance tasks performed, and the PMT matrix specified temperature stabilization for bearing replacements. In addition, the licensee concluded from the root cause that: people interviewed, who were involved with the PMT recommendation, approval, and review process rely on the applicable procedure to be correct and do not verify that the correct PMT is specified in the procedures; many operations, engineering, and planning personnel rely on memory when assigning PMT to work that does not have a procedure-based PMT; and additional training may be necessary for PMT activities.
| |
| | |
| Past Operability and Availability Analysis From July through December 2007, the licensee evaluated the past operability and availability of the Unit 1 TDAFW pump. The inspectors, in conjunction with a technical matter expert from the Office of Nuclear Reactor Regulation and a Regional Senior Reactor Analyst, reviewed the licensee's past availability analysis, and verified the assumptions, calculations, and conclusions made by the licensee in AR 01090456, "Past Availability 1P-29 Turbine Driven Auxiliary Feedwater Pump." The inspectors verified the conclusion made by the licensee that the as-found condition of the turbine would have resulted in the turbine being able to perform its function for the 24-hour mission time. The as-found condition consisted of the following known deficiencies caused by the spring 2007 maintenance: inadequate wheel lap setting, inadequate pump-to-turbine coupling stretch; inadequate stretch and misalignment in the gear box coupling; and 39 Enclosure inadequate thrust bearing axial end clearance. The basis for concluding that the TDAFW pump would have performed its function were as follows: the accumulated run time without component degradation provided indications of satisfactory operation of components other than the bearing; the vibration measurements of the turbine and pump were satisfactory and indicated normal operation; oil analysis for the bearings were acceptable; IST data for the pump indicated no appreciable difference between the results prior to and after the overhaul of the turbine; outboard bearing temperatures, while significantly higher than normal, were determined via analysis by a vendor and concurrence by the turbine manufacturer to stabilize at a temperature that was acceptable for a 24-hour mission time; analysis demonstrated that adjacent turbine components would not be affected by the increased bearing temperature; analysis of the oil at increased temperatures by the oil vendor demonstrated no significant decrease in oil properties; and the increased bearing temperatures were evaluated by the bearing manufacturer and determined not to affect the operation of the bearing for a 24-hour mission time.
| |
| | |
| =====Analysis:=====
| |
| The inspectors determined the failure to have adequate PMT of the TDAFW pumps was a performance deficiency and a finding. Using IMC 0612, "Power Reactor Inspection Reports," Appendix B, "Issue Screening," dated September 20, 2007, the inspectors determined that this finding is more than minor because if left uncorrected, the failure would become a more significant issue. Using IMC 0609, Appendix A, "Determining the Significance of Reactor Inspection Findings for At-Power Situations," Attachment 1, "SDP Phase 1 Screening Worksheet for IE, MS, and B Cornerstones," dated January 10, 2008, the inspectors determined that the finding did not result in an actual loss of safety function of a system or train of equipment. Therefore, the finding is considered to be of very low safety significance (Green). The inspectors also determined that this finding had a cross-cutting aspect in the area of human performance because the licensee did not ensure that procedures were adequate and accurate to assure nuclear safety (H.2(c)).
| |
| | |
| =====Enforcement:=====
| |
| 10 CFR 50, Appendix B, Criterion V, requires, in part, that activities affecting quality be prescribed and accomplished by procedures appropriate to the circumstances. Contrary to this, the licensee failed to prescribe and accomplish adequate PMT with procedures appropriate to the circumstances to ensure that after maintenance on safety-related equipment, the equipment returned to service in an operable condition, an activity affecting quality. Because this finding was of very low safety significance (Green) and because the finding was entered into the licensee's corrective action program (as CAP 01090456), this violation is being treated as a Non-Cited Violation (NCV 05000266/2007005-05; NCV 05000301/2007005-05), consistent with Section VI.A of the NRC Enforcement Policy. The licensee took immediate corrective actions to address the issue by revising the appropriate procedures, and at the end of the inspection period the licensee continued to implement planned corrective actions.

| | |
| Emergent Issue (95003)
| |
| | |
| ====b. Inspection Scope====
| |
| The inspectors utilized additional inspection hours allowed by IMC 0305 "Operating Reactor Assessment Program," since Point Beach exited Column IV of the NRC's Action Matrix in 2007, to assess the licensee's organizational response to a significant issue associated with the Unit 2 2P-29 TDAFW pump in November 2007. In particular, the inspectors focused on the organizational use of human performance tools, the performance of operations and engineering personnel during the issue, and utilization of the corrective action program by the organization.
| |
| | |
| Increased water in the outboard bearing of TDAFW pump 2P-29 was first observed in June 2007. The licensee performed an operability evaluation at that time and concluded that the pump was operable because the concentration of the oil was below the 5,000 pm threshold value for operability established by the licensee, based on Electric Power Research Institute (EPRI) and vendor guidance. Test results revealed in June 2007 that the water concentration was approximately 140 ppm and in July compensatory testing identified an increase to 760 ppm. The licensee continued to trend increasing water in the oil and developed a contingency plan. On September 21, the oil sample results revealed water levels had increased to 3,845 ppm, and during the 2P-29 TDAFW pump run, an outboard high temperature alarm occurred. In addition, operators noted that additional leakage was observed from the turbine outboard gland area. The licensee commenced implementation of the contingency plan, which included a pump overhaul. The overhaul was completed on September 23, and included replacement of the turbine shaft carbon seal rings and the turbine outboard gland seal casing. The gland and turbine casings were then sealed with high temperature silicone per the maintenance procedure. The TDAFW pump was run and oil samples were collected. The water content was visually estimated at 1,500 ppm, and the licensee concluded that they were within the bounds of the previous operability evaluation. A second test run conducted that day revealed less water visually than the first run. Both samples were sent offsite for analysis. On September 27, the lab results were received, with the first run showing 20,400 ppm of water and the second run showing only 56 ppm of water. Condition report CAP 01113318 was written; however, the description discounted the higher sample based on conformational biases of the personnel involved, specifically: high room humidity; statements from a vendor representative noting that increased leakage may be expected following overhauls (even though this had never been seen on the identical turbine for the opposite unit); and high humidity in the room where the samples were split for offsite analysis. Consequently, CAP 01113318 was closed with no action taken. On November 1, 2P-29 was run twice and the water content in the oil was analyzed at 29,515 ppm for the first run and 17,700 ppm for the second run, supporting the September 2007 value of 20,400 ppm of water as a valid result. The licensee subsequently initiated its event response procedure. Revision 2 of operability Evaluation OPR01098358 was performed and completed on November 3, and required a compensatory measure of running the turbine and sampling the oil every 72 hours.
| |
| | |
| Over the next several days, the TDAFW pump was run for eight hours, every 72 hours.
| |
| | |
| 41 Enclosure Additional data and responses by the licensee to the inspectors questions necessitated three additional revisions of the OPR by November 10. On November 13, due to the continued high water content, the licensee elected to overhaul the turbine. The licensee, with vendor assistance, identified the following significant as-found conditions during the overhaul: a gap in the aluminum oil deflector ring attached to the turbine shaft by a set screw, that provided a direct path for steam to enter the bearing housing along the turbine shaft; the silicone sealant, particularly around the gland housing and casing, exhibited a lack of adhesion, also providing a path for steam entering; and the gland housing, which was replaced in the September 2007 maintenance, was undersized. Following the November 2007 overhaul, the pump underwent PMT and the outboard bearing oil samples showed less than 100 ppm of water.
| |
| | |
| ====c. Findings====
| |
| The inspectors identified three Green findings with associated NCVs as a result of the inspection activities. Two findings are documented in this Section and a third is documented in Section 1R15.2 of this report. b.1 Failure to Take Adequate Corrective Actions to Address Water Ingress Following Maintenance
| |
| | |
| =====Introduction:=====
| |
| The inspectors identified a Non-Cited Violation (NCV) of 10 CFR 50, Appendix B, Criterion XVI, "Corrective Action," having very low safety significance (Green) for the licensee's failure to take prompt corrective actions to correct the cause of increased water in the 2P-29 TDAFW pump turbine outboard bearing housing, a condition adverse to quality, originally identified in September 2007.
| |
| | |
| =====Description:=====
| |
| On September 24, 2007, following the overhaul of the 2P-29 TDAFW pump turbine, an oil sample was taken from the outboard bearing housing, following a four hour run. CAP 01112660 was written, which documented water volume in the oil sample of 1,000 to 1,500 ppm for the four-hour run. The CAP description concluded that this was an expected condition. A second shorter pump run was performed, and the water content in the oil was visually estimated to be 100 ppm. The licensee rationalized that the initial water content was expected and the CAP was closed with no further actions taken. Three days later, CAP 01113318 was written and documented that the outboard oil sample from the first four-hour run was actually 20,040 ppm water, and that the number was not consistent with the visual indications seen on September 24. The description in the CAP was presented in a manner which refuted the results based on conjecture, concluding that the 20,040 ppm results were false readings due to a laboratory error or an accidental capture of water droplets during the sampling process. The CAP concluded that, "the indicated levels of water in the IT-09A sample are errant." The CAP was screened by licensee staff and no additional actions were taken to either characterize the cause of the unexplained increase of water in the oil, or to further evaluate this unexpected condition identified through testing of the safety-related oil, following the four-hour TDAFW pump run. The licensee did not consider as a corrective action, running the pump and obtaining another oil sample to verify that the abnormally high water content following the overhaul was a false indication. On November 1, approximately five weeks after the maintenance overhaul, the licensee ran 2P-29 and sampled the oil. The frequency of running the pump once per month was established in June 2007, when the moisture in the turbine outboard bearing oil was 42 Enclosure significantly less than the EPRI and vendor recommended 5,000 ppm. The pump was run slightly more than two hours and the outboard oil sample drawn revealed 29,515 ppm of water in the oil. After the pump had not run for about eight hours and was then run for eight hours, 17,700 ppm was found in the outboard bearing oil. The licensee declared the pump inoperable and revised the original June 2007 operability evaluation. As described previously, on November 13, the licensee began an overhaul of the turbine. The inspectors determined that the original unsatisfactory oil sample results in September 2007 identified a condition adverse to quality associated with the safety-related 2P-29 TDAFW pump; however, prompt corrective actions were not taken.
| |
| | |
| =====Analysis:=====
| |
| The inspectors determined that the licensee's failure to implement prompt corrective actions to address the September 2007 2P-29 TDAFW pump turbine degraded oil sample results, a condition adverse to quality, was a performance deficiency and a finding. The inspectors concluded that the finding is more than minor in accordance with IMC 0612, "Power Reactor Inspection Reports," Appendix B, "Issue Screening," dated September 20, 2007, in that the finding could reasonably be viewed as a precursor to a significant event. Specifically, the failure to promptly correct the cause of the oil degradation in a timely manner could result in failure of the TDAFW turbine.
| |
| | |
| The significance of this finding was evaluated using IMC 0609, Appendix A, "Determining the Significance of Reactor Inspection Findings for At-Power Situations," dated January 10, 2008, for the Mitigating Systems Cornerstone. The risk assessment for the potential loss of safety function is attributed to the performance deficiencies associated with inadequate maintenance discussed in Section 4OA5.2.b.2 as URI 5000266/2007005-07. This finding, for the failure to implement prompt corrective actions, did not cause the loss of safety function for greater than the allowed outage time. The inspectors determined that the finding is of very low safety significance (Green), because the finding did not involve a design deficiency, there was no actual loss of safety function, no single train loss of safety function for greater than the TS allowed outage time, and no risk due to external events. The licensee concluded that although the pump was initially declared inoperable and the oil was degraded, the TDAFW pump would have performed its specified safety function. Additionally, the inspectors determined that the finding had a cross-cutting area aspect in the area of problem identification and resolution. Specifically, the licensee failed to thoroughly evaluate the problem with water ingress into the oil, such that a resolution addressed the cause and extent of condition (P.1(c)).
| |
| | |
| =====Enforcement:=====
| |
| 10 CFR 50, Appendix B, Criterion XVI, "Corrective Action," requires, in part, that measures be established to assure that conditions adverse to quality, such as malfunctions, deficiencies, deviations, defective equipment and nonconformances are promptly identified and corrected. Contrary to this, a condition adverse to quality, associated with the turbine of the Unit 2 TDAFW pump 2P-29 was not promptly corrected following identification in September 2007. Specifically, upon identification of degraded oil in September 2007, a condition adverse to quality, the licensee did not take prompt corrective actions. As a result of the failure to take prompt corrective actions, the pump was declared inoperable until November 2007, following additional oil samples that revealed the continued degraded condition. Because of the very low safety significance of this finding and because it was entered into the licensee's corrective 43 Enclosure action program as CAP 01115748, this violation is being treated as an NCV, consistent with Section VI.A.1 of the NRC Enforcement Policy (NCV 05000301/2007005-06). The licensee took immediate corrective actions to address the issue, which included reevaluation of operability and ultimately overhaul of 2P-29, and at the end of the inspection period the licensee continued to evaluate the causes associated with this finding. b.2 Unresolved Item: Failure to Perform Adequate Maintenance Resulting in Increased Water Ingress
| |
| | |
| =====Introduction:=====
| |
| The inspectors identified a URI associated with the licensee's failure to perform adequate maintenance on the Unit 2 TDAFW pump turbine in September 2007.
| |
| | |
| =====Description:=====
| |
| The elevated moisture content in the outboard bearing for the 2P-29 turbine was present since the last ten-year overhaul was performed in November 2006. However, while the moisture content levels in the oil from November 2006 until the September 21, 2007, overhaul were elevated, the levels were below the 5,000 ppm value documented as acceptable in EPRI and vendor guidance. Steam leakage from the gland seal or turbine casing joints prior to the September overhaul would not have been vented away from the bearing housing since the turbine insulation extended over the top of the gland seal casing and up to the bearing housing. In addition, original cement-based insulation also blocked the gland seal area vent holes. The licensee concluded, based on test data, that the 2P-29 turbine overhaul that was completed on September 23, 2007, significantly increased the moisture content in the outboard bearing oil. A silicone seal applied at the gland casing to turbine casing joint failed upon initial service resulting in a steam leak in the area of the outboard bearing housing. The failure of the sealant could not be attributed to one factor; however, the licensee did conclude one of the root causes was its maintenance procedures did not address the special requirements needed when applying sealants, and, therefore, site personnel did not have adequate instruction or training on the use of sealants. In addition, the licensee identified that the September 2007 maintenance did not allow for the proper cure time of 24 hours for the sealant and exceeded the process time of 30 minutes from when the sealant was applied and the joint was torqued. In a review of the site maintenance procedures, the licensee also identified an additional root cause that the site continued to lack adequate guidance on specific assembly details of the turbine, specifically for the oil deflector ring on the turbine shaft: the tightening of the oil deflector ring set screw was not discussed; and acceptable clearances between the turbine shaft and the inner diameter of the oil deflector ring were not specified. The licensee identified three additional contributing causes: receipt and installation of a gland casing from the vendor that had incorrect critical dimensions; previous insulation work blocked the gland seal vents; and plant personnel did not have adequate guidance on the installation of insulation. At the end of the inspection period, the licensee continued to develop and implement corrective actions to address the issues documented in CAP 01115748.
| |
| | |
| 44 Enclosure At the conclusion of the inspection, the licensee continued to assess the impact of the water ingress on the availability of the Unit 2 TDAFW pump to perform its design and augmented quality functions. There is no current safety concern because the pump was adequately tested and the current low ingress of water into the bearing housing indicated that the pump's functionality is currently maintained for all licensing and design basis events. This issue is an Unresolved Item (URI 05000301/2007005-07) until the NRC reviews the licensee's past availability assessment.

| |
| {{IP sample|IP=IP 95003}}
| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors utilized additional inspection hours allowed by IMC 0305, since Point Beach exited Column IV of the NRC's Action Matrix in 2007, to assess the licensee's independent assessment of engineering. The licensee committed as part of its response to the Confirmatory Action Letter CAL 3-04-001, Revision 1, dated April 14, 2006, to perform alternating independent and self-assessments of the engineering and corrective action programs. In July 2007, the licensee performed an independent assessment of engineering performance. The inspectors reviewed the charter for the assessment, observed the independent assessment team, reviewed the final report, and reviewed the proposed corrective actions.
| |
| | |
| b. Observations and Assessment The team consisted of four experienced individuals from other utilities and a consulting firm. The team assessed licensee engineering performance in five areas: fundamentals of engineering, equipment reliability, configuration management, corrective actions, and operating experience. The assessment team's overall conclusions were: engineering rigor and overall quality has improved and has been sufficient for successful management of potential challenges to design bases and equipment reliability; unresolved plant material conditions present substantial ongoing challenges; a plateau may have been reached for engineering improvement; and additional resources and continued effort will be required to sustain the improvements that have already been obtained and to bridge the remaining gaps to engineering excellence.
| |
| | |
| The assessment team identified the following overall issues for attention: most recent engineering products are of high quality, but examples of products with less than adequate rigor are still produced; engineering needs to be more predictable and accountable with respect to schedules; important longstanding issues were not resolved; engineering resources may not be adequately matched to engineering obligations; the preventive maintenance optimization and single point vulnerability projects have languished and, as a consequence, the station had not benefited from the improved material condition and safety margins; although a list of low margin issues had been established, there did not appear to be a quantification of the lost margin associated with these issues or an evaluation of the cumulative effects; it was not clear that cumulative effects of conditions adverse to quality were being addressed and the large number of open conditions presented a challenge to effectiveness of such a review; and the corrective action process was not used to the full potential, specifically: trending was not being used as effectively as it could be; more effective use of corrective action processes for vendor products was warranted; and expectations for a close to fix solution, versus an apparent cause evaluation warranted examination.
| |
| | |
| 45 Enclosure The overall recommendations from the assessment team were 1) to maintain highly visible management commitment to rigor and continue associated empowerment, and 2) to implement the specifically identified corrective actions for issues with predictability, resolution of longstanding issues, prevent maintenance optimization, cumulative effects of material condition, more aggressive use of corrective action processes, margin issues, and engineering resources. The inspectors confirmed that the licensee had developed plans and corrective actions to address the issues for attention identified by the Independent Assessment Team.

| |
| | |
| ====a. Inspection Scope====
| |
| The inspectors utilized additional inspection hours allowed by IMC 0305, since Point Beach exited Column IV of the NRC's Action Matrix in 2007, to assess the licensee's independent assessment of the corrective action program. The licensee committed as part of its response to the Confirmatory Action Letter CAL 3-04-001, Revision 1, dated April 14, 2006, to perform alternating independent and self-assessments of the engineering and corrective action programs. The inspectors reviewed the charter for the assessment of the corrective action program in August 2007, observed the independent assessment team, reviewed the final report, and reviewed the proposed corrective actions. b. Observations and Assessment The team consisted of four experienced individuals from other utilities and a consulting firm. The team concluded that although measurable improvement in the corrective action program had been achieved over the last 12 months, several opportunities for improvement needed to be addressed in order to achieve improved performance. The team noted the following opportunities for improvement: the effectiveness and quality of apparent cause evaluations needed to be improved; the number of corrective action program performance indicators above target with no detailed recovery plan indicated that timeliness continued to be an issue, corrective action program backlog, in particular, has been increasing; the ease of CAP initiation via computer (Passport software) and providing feedback to the CAP initiator for CAPs which are closed by the management screening committee with no action; trending has not been effective at identifying adverse trends through the quarterly Department Roll-Up Meetings and Passport issues continue to impede trending; effectiveness reviews for corrective actions to prevent recurrence needed to consider effectiveness from a broader perspective; additional opportunities for improvement were identified in apparent cause evaluations for NRC-identified findings and on the effectiveness of certain actions specified to correct the January 2007 corrective action program self-assessment issues. The independent assessment team concluded that some positive features of the corrective action program included: management was highly engaged in the program and the screening committee appears to be highly effective; root cause evaluations were thorough and comprehensive, and effectiveness review criteria were clearly specified; format consistency has improved for apparent cause evaluations, effectiveness reviews, and department roll-up meeting reports; the Performance Assessment Review Board was involved in reviewing the backlog of open CAPs by department; and most actions 46 Enclosure taken to address issues from the January 2007 corrective action program self-assessment had resulted in measurable improvement. The inspectors confirmed that the licensee had developed plans and corrective actions to address the opportunities for improvement identified by the Independent Assessment Team.

| Inadequate 10 CFR 72.48 Screening to Evaluate Possible Thermal Effects on Fuel Cladding
| |
| | |
| =====Introduction:=====
| |
| The inspectors identified one violation of 10 CFR 72.48(c)(1) in which the licensee failed to obtain a Certificate of Compliance (CoC) amendment pursuant to 10 CFR 72.244 for changes made in the spent fuel storage cask operating procedures during the 2004 loading campaign as described in the FSAR and these changes in the procedures constituted a change in the terms, conditions, or specifications incorporated in the CoC. Specifically, although Point Beach changed an operating procedure described in the FSAR that allowed pump down of water from the dry shielded canister to occur much earlier in the process; Point Beach failed to identify that the following TS, which was incorporated in the CoC, would have required changes that needed prior NRC approval: TS 1.2.17a, "32PT Dry Storage Canister (DSC) Vacuum Drying Duration Limit."
| |
| | |
| =====Description:=====
| |
| During the fall 2004 campaign, the licensee used the new NUHOMS 32-PT cask design and modified the sequence of its loading procedures from the generic operating procedures stated in Chapter M.8 of the FSAR. The change consisted of draining all of the water from the canister cavity prior to welding the inner top cover on, whereas the FSAR prescribed draining some of the water from the canister (approximately 750 gallons), then welding the top inner cover and then draining the remainder of the water from the canister. In the 10 CFR 72.48 screening, the licensee failed to evaluate the effect of the water removal during draining and welding on the fuel cladding temperature. The inadequate screening failed to identify that TS 1.2.17a, "32 PT DSC Vacuum Drying Duration Limit," which was incorporated in the CoC, would have required a change that needed prior NRC approval. This amendment to the CoC would address any affects on the vacuum drying time limits that may result from the potentially higher fuel cladding temperature. The initial fuel cladding temperature, at the start of vacuum drying in the procedure that deviated from the FSAR, could be higher than the FSAR assumed value of 215 °F. An assumed temperature of the fuel cladding higher than the 215 °F basis in the FSAR may result in a shorter vacuum drying time than that specified in TS 1.2.17a. The licensee loaded five casks utilizing the different loading process. Subsequently, in 2006, the licensee's cask vendor, Transnuclear, performed a NUHOMS 32PT drain down evaluation (Calculation No. NU32PT-0420) to address the issues with the vacuum drying duration limit and fuel cladding temperature. The inspectors reviewed the calculation, which concluded that the maximum fuel cladding temperature for the 32PT DSC with a heat load of 16.88 kilowatts (kW) (highest heat load for the 32PT DSC amongst users of this canister at the time) was 720 °F. The 720 °F temperature was below the allowable limit of 752 °F. Therefore, no time limitation was necessary for vacuum drying of the 32PT DSC when the total decay heat load was 16.88 kW or below.
| |
| | |
| 47 Enclosure Transnuclear also performed another evaluation (Calculation NUH32PT-0421) in which it modeled a loading configuration that resulted in the maximum fuel cladding temperature for vacuum drying. This loading configuration produced a 22.4 kW total heat load. TS 1.2.17a stated that the limit for duration of vacuum drying was 31 hours for a 32PT DSC with a heat load greater than 8.4 kW and up to 24 kW after initiation of vacuum drying. This value of 22.4 kW total maximum heat load was within the maximum TS fuel cladding temperature for the 24 kW heat load. The results of this evaluation justified using a constant temperature of 215 °F for DSC during handling, welding, and vacuum drying operations, and indicated that after 31 hours of vacuum drying the maximum fuel cladding temperature was 739 °F, below the allowable limit of 752 °F. The maximum fuel cladding temperature reached the allowable limit of 752 °F at 67 hours after the start of the DSC drainage. Thus, the evaluation concluded that the time limit of 31 hours for vacuum drying was acceptable.
| |
| | |
| =====Analysis:=====
| |
| The inspectors determined that the failure to obtain a CoC amendment pursuant to 10 CFR 72.244 for changes made in the spent fuel storage cask operating procedures, as described in the FSAR, was a performance deficiency and a finding. This finding is more than minor because it had the potential to impact the NRC's ability to perform its regulatory function, since the licensee failed to receive NRC approval for a change in this licensed activity. A CoC amendment was required since these changes in the procedures constituted a change in the terms, conditions, or specifications incorporated into the CoC. The inspectors determined that the finding was not suitable for SDP evaluation because the noncompliance involved 10 CFR Part 72 dry fuel storage activities. Therefore, this finding was reviewed by Regional Management and dispositioned using traditional enforcement.
| |
| | |
| =====Enforcement:=====
| |
| 10 CFR 72.48(c)(1) states, in part, that a certificate holder may make changes in the facility or spent fuel storage cask design as described in the FSAR (as updated), make changes in the procedures as described in the FSAR (as updated), without obtaining:
| |
| : (a) a Certificate of Compliance (CoC) amendment submitted by the certificate holder pursuant to 10 CFR 72.244; if:
| |
| : (b) a change in the terms conditions, or specifications incorporated in the CoC is not required; and
| |
| : (c) the change, test, or experiment does not meet any of the criteria in paragraph in 10 CFR 72.48(c)(2). Contrary to this, in an approved 10 CFR 72.48 evaluation, Point Beach failed to obtain a CoC amendment pursuant to 10 CFR 72.244 for changes made in the spent fuel storage cask operating procedures as described in the FSAR (as updated) and these changes in the procedures constituted a change in the terms, conditions, or specifications incorporated in the CoC. Specifically, although Point Beach changed an operating procedure described in the FSAR which allowed pump down of water from the dry shielded canister to occur much earlier in the process; Point Beach failed to identify that the following TS, which was incorporated in the CoC, would have required changes that needed prior NRC approval: TS 1.2.17a, "32PT DSC Vacuum Drying Duration Limit." Because this violation was of very low safety significance, was not repetitive or willful, and was entered into your corrective action program, this violation is being treated as an NCV of 10 CFR 72.48(c)(1), consistent with Section VI.A.1 of the NRC Enforcement Policy (NCV 05000266/2007005-09; 05000301/2007005-09). The licensee entered the issue into the corrective action program as CAP 01026070 and implemented corrective actions, including revising the loading procedure to reflect the sequence described in the FSAR prior to loading the next cask (cask 6).

| Adequacy of Design Calculation, PBNP-305336-SO1 During an October through December 2004 NRC inspection, inspectors identified one URI associated with the adequacy of the licensee's auxiliary building structure and the crane design basis during a seismic event. The licensee received an NCV of 10 CFR 72.122(2)(i), documented in Inspection Report 07200005/2004-003(DNMS),
| |
| regarding failure to demonstrate that the crane, a component important to safety, was designed to withstand the effects of an earthquake without impairing its capability to perform its intended function. Upon further review, the inspectors identified other deficiencies in the structural analysis of the building and the crane for which the URI was opened. There was no response spectra analysis performed on the building to model its response due to an earthquake at different elevations, such as that of the crane. Also, the inspectors could not independently verify that the basis for the horizontal accelerations in all of the calculations used for the auxiliary building and the crane were adequate. In response to these questions, the licensee constructed a detailed computer model of the steel portion of the auxiliary building. The preliminary results from an analysis using this model demonstrated that the original acceleration values were conservative and adequate to demonstrate compliance with regulations and the ability of the building and the crane to sustain up to a 125-ton load under an earthquake scenario. In addition, the licensee hired an independent consultant who confirmed the licensee
| |
| =s results. The inspectors were not able to validate these conclusions since the appropriate documentation was not available at the time of the inspection and a complete analysis was not completed. However, the licensee committed to perform a full analysis of the auxiliary building and the crane response under a seismic event with the current plant conditions. The licensee performed an analysis of the Class 3 Primary Auxiliary Building (PAB) Steel Superstructure in Calculation PBNP-305336-SO1, "Structural Analysis of Central PAB with Crane Load of 125 Tons," Revision 1, dated April 3, 2006. During the current inspection, NRC staff reviewed the calculation results and discussed the assumptions with licensee personnel. The analysis demonstrated the capability of the structure to support the crane with a load of 125 tons in case of a seismic event once the welded connection of the gusset and Columns 10U and 13U were strengthened. Thus, the calculation verified that the requirements of NUREG-0612 and 10 CFR 72.122(b)(2)(i) were satisfied. The inspectors concluded that the revised calculation was adequate to demonstrate compliance with regulations and the ability of the building and the crane to sustain up to a 125-ton load under an earthquake scenario.
