REACTOR SAFETY

Cornerstone: Initiating Events, Mitigating Systems, and Barrier Integrity

1R01 Adverse Weather Protection

.1 Winter Seasonal Readiness Preparations

a. Inspection Scope

The inspectors conducted a review of the licensees preparations for winter conditions to verify that the plants 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 licensees procedures used to mitigate or respond to adverse weather conditions. Additionally, the inspectors reviewed the Updated Final Safety Analysis Report (UFSAR) and performance requirements for systems selected for inspection, and verified that operator actions were appropriate as specified by plant specific procedures. Cold weather protection, such as heat tracing and area heaters, was verified to be in operation where applicable. The inspectors also reviewed corrective action program (CAP) items to verify that the licensee was identifying adverse weather issues at an appropriate threshold and entering them into their CAP in accordance with station corrective action procedures.

Specific documents reviewed during this inspection are listed in the Attachment. The inspectors reviews focused specifically on the following plant systems due to their risk significance or susceptibility to cold weather issues:

  • condensate storage tank; and
  • safety injection and refueling water storage tank.

This inspection constituted one winter seasonal readiness preparations sample as defined in Inspection Procedure (IP) 71111.01-05.

b. Findings

No findings of significance were identified.

.2 Readiness for Impending Adverse Weather Condition - Frazil Ice Prevention

a. Inspection Scope

On December 17, 2009, weather conditions conducive to frazil ice formation were present. The inspectors reviewed licensee procedures regarding frazil ice prevention and ensured appropriate actions were taken. The inspectors also performed a walkdown of systems used to detect and mitigate frazil ice, which included observations of operator performance in the field and equipment functionality. Specific documents reviewed during this inspection are listed in the Attachment.

This inspection constituted one readiness for impending adverse weather condition sample as defined in IP 71111.01-05.

1R04 Equipment Alignment

a. Inspection Scope

The inspectors performed partial system walkdowns of the following risk-significant systems:

  • P66A high pressure safety injection (HPSI) pump during B HPSI outage;
  • right train emergency cooling systems with left train components out-of-service.

The inspectors selected these systems based on their risk significance relative to the Reactor Safety Cornerstones at the time they were inspected. The inspectors attempted to identify any discrepancies that could impact the function of the system, and, therefore, potentially increase risk. The inspectors reviewed applicable operating procedures, system diagrams, UFSAR, Technical Specification (TS) requirements, outstanding work orders (WOs), condition reports, and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions. The inspectors also walked down accessible portions of the systems to verify system components and support equipment were aligned correctly and operable. The inspectors examined the material condition of the components and observed operating parameters of equipment to verify that there were no obvious deficiencies. The inspectors also verified that the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact the capability of mitigating systems or barriers and entered them into the CAP with the appropriate significance characterization. Documents reviewed are listed in the

.

These activities constituted four partial system walkdown samples as defined in IP 71111.04-05.

1R15 Operability Evaluations

a. Inspection Scope

The inspectors reviewed the following issues:

  • pressurizer heaters following loss of heaters;
  • reduced recirculation flow in high pressure safety injection pump P-66A during test.

The inspectors selected these potential operability issues based on the risk significance of the associated components and systems. The inspectors evaluated the technical adequacy of the evaluations to ensure that TS operability was properly justified and the subject component or system remained available such that no unrecognized increase in risk occurred. The inspectors compared the operability and design criteria in the appropriate sections of the TS and UFSAR to the licensees evaluations, to determine whether the components or systems were operable. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations. Additionally, the inspectors also reviewed a sampling of corrective action documents to verify that the licensee was identifying and correcting any deficiencies associated with operability evaluations. Documents reviewed are listed in the to this report.

Unresolved Item 20090005-02 Adequacy of Evaluation of Interface with State and Local Governments

Introduction:

The inspector reviewed the quality assurance audits conducted pursuant to 10 CFR 50.54(t) for the adequacy of the independent evaluation of the interface of the licensee with State and local governments.

Description:

For the Palisades Nuclear Power Plant EPZ, Michigan Department of State Police Emergency Management Division is the leading state agency for emergency response planning and operations. The local governments in the EPZ include Allegan, Berrien, and Van Buren counties. In the 2008 Quality Assurance audit report, the auditor evaluated the interface of the licensee with State and local Governments as satisfactory. The auditor made contact with officials from the Michigan State Police, Allegan, and Van Buren County. During the 2009 audit, the auditor made contact with Berrien County and also evaluated the interface as adequate.

Palisades follows the Entergy Nuclear Emergency Plan Master Audit Plan which lists the evaluation of the adequacy of the interfaces with State and local governments as a mandatory core scope element. The licensee reported the mandatory scope elements are to be evaluated during the surveillance conducted every 12 months. The Entergy Nuclear Management Manual states the audits of the emergency preparedness program must review all elements of the program at least once every 24 months. If an audit is to be performed beyond 12 months from the previous audit, an assessment shall be performed to include performance indicators. Pending review of additional information requested from the licensee concerning the licensees methods and performance indicators for evaluating the adequacy of the interface with the State and local governments in order to determine if the audit plan and schedule met the requirements of 10 CFR 50.54(t), this issue is considered an Unresolved Item (URI),05000255/2009005-02.

RADIATION SAFETY

2OS1 Access Control to Radiologically Significant Areas (71121.01)

a. Inspection Scope

The inspectors reviewed the licensees Occupational Exposure Control Cornerstone performance indicator (PI) to determine whether the conditions resulting in any PI occurrences had been evaluated and whether identified problems had been entered into the licensees CAP for resolution.

This inspection constituted one sample as defined in IP 71121.01-5.

b. Findings

The inspectors reviewed the status and surveillance records of self-contained breathing apparatus that were staged in the plant and ready-for-use and evaluated the licensees capabilities for refilling and transporting self-contained breathing apparatus air bottles to-and-from the control room and operations support center during emergency conditions. The inspectors determined if control room staff and other emergency response and Radiation Protection personnel were trained, respirator fit tested, and medically certified to use self-contained breathing apparatus, including personal bottle change-out. Additionally, the inspectors reviewed self-contained breathing apparatus qualification records for numerous members of the licensees radiological emergency teams to determine if a sufficient number of staff were qualified to fulfill emergency response positions, consistent with the licensees emergency plan and the requirements of 10 CFR 50.47.

This inspection constituted one sample as defined in IP 71121.03-5.

The inspectors reviewed the qualification documentation for at least 50 percent of the onsite, or as applicable, offsite contract personnel that performed maintenance on manufacturer designated vital self-contained breathing apparatus components. The inspectors also reviewed vital component maintenance records for several self-contained breathing apparatus units that were designated as ready-for-use. The inspectors also evaluated, through record review and observations, if the required air cylinder hydrostatic testing was documented and current and if the Department of Transportation required retest air cylinder markings were in place for several randomly selected self-contained breathing apparatus units and spare air bottles. The inspectors reviewed the onsite maintenance procedures governing vital component work, as applicable, including those for the low-pressure alarm and pressure-demand air regulator. The inspectors reviewed the licensees maintenance procedures and the self-contained breathing apparatus manufacturers recommended practices to determine if there were any inconsistencies between them.

This inspection constituted one sample as defined in IP 71121.03-5.

b. Findings

No findings of significance were identified.

2PS1 Radioactive Gaseous and Liquid Effluent Treatment and Monitoring Systems (71122.01)

.1 Inspection Planning

a. Inspection Scope

The inspectors reviewed the configuration of the licensees gaseous and liquid effluent processing systems to confirm that radiological discharges were properly mitigated, monitored, and evaluated with respect to public exposure. The inspectors reviewed the performance requirements contained in General Design Criteria 60 and 64 of Appendix A to 10 CFR Part 50 and in the licensees Radiological Effluent Technical Specifications and Offsite Dose Calculation Manual. The inspectors also reviewed any abnormal radioactive gaseous or liquid discharges and any conditions since the last inspection when effluent radiation monitors were out-of-service to verify that the required compensatory measures were implemented. Additionally, the inspectors reviewed the licensee=s quality control program to verify that the radioactive effluent sampling and analysis requirements were satisfied and that discharges of radioactive materials were adequately quantified and evaluated.

The inspectors reviewed each of the radiological effluent controls program requirements to verify that the requirements were implemented as described in the licensees Radiological Effluent Technical Specifications. For selected system modification (since the last inspection), the inspectors reviewed changes to the liquid or gaseous radioactive waste system design, procedures, or operation, as described in the UFSAR and plant procedures.

The inspectors reviewed changes to the Offsite Dose Calculation Manual made by the licensee since the last inspection to ensure consistency was maintained with respect to guidance in NUREG-1301, 1302, and 0133, and Regulatory Guides 1.109, 1.21, and 4.1. If differences were identified, the inspectors reviewed the licensees technical basis or evaluations to verify that the changes were technically justified and documented.

The inspectors reviewed the radiological effluent release report(s) for 2007 and 2008 in order to determine if anomalous or unexpected results were identified by the licensee, entered in the CAP, and adequately resolved.

The inspectors reviewed any significant changes in reported dose values from the previous radiological effluent release report, and the inspectors evaluated the factors which may have resulted in the change. If the change was not explained as being influenced by an operational issue (e.g., fuel integrity, extended outage, or major decontamination efforts), the inspectors independently assessed the licensee=s offsite dose calculations to verify that the licensees calculations were adequately performed and were consistent with regulatory requirements.

The inspectors reviewed the licensees correlation between the effluent release reports and the environmental monitoring results, as provided in Section IV.B.2 of Appendix I to 10 CFR Part 50.

This inspection constitutes one sample as defined by Inspection Procedure 71122.01-5.

b. Findings

No findings of significance were identified.

.2 Onsite Inspection

a. Inspection Scope

The inspectors performed a walkdown of selected components of the gaseous and liquid discharge systems (e.g., gas compressors, demineralizers and filters (in use or in standby), tanks, and vessels) and reviewed current system configuration with respect to the description in the UFSAR. The inspectors evaluated temporary waste processing activities, system modifications, and the equipment material condition. For equipment or areas that were not readily accessible, the inspectors reviewed the licensee's material condition surveillance records, as applicable. The inspectors reviewed any changes that were made to the liquid or gaseous waste systems to verify that the licensee adequately evaluated the changes and maintained effluent releases as low as reasonably achievable.

During system walkdowns, the inspectors assessed the operability of selected point of discharge effluent radiation monitoring instruments and flow measurement devices. The effluent radiation monitor alarm set point values were reviewed to verify that the set points were consistent with Radiological Effluent Technical Specifications/Offsite Dose Calculation Manual requirements.

For effluent monitoring instrumentation, the inspectors reviewed documentation to verify the adequacy of methods and monitoring of effluents, including any changes to effluent radiation monitor set-points. The inspectors evaluated the calculation methodology and the basis for the changes to verify the adequacy of the licensees justification.

The inspectors observed the licensees sampling of liquid and gaseous radioactive waste (e.g., sampling of waste steams) and observed selected portions of the routine processing and discharge of radioactive effluents if those activities occurred during the onsite inspection. Additionally, the inspectors reviewed several radioactive effluent discharge permits, assessed whether the appropriate treatment equipment was used and whether the radioactive effluent was processed and discharged in accordance with Radiological Effluent Technical Specifications/Offsite Dose Calculation Manual requirements, including the projected doses to members of the public.

The inspectors interviewed staff concerning effluent discharges made with inoperable (declared out-of-service) effluent radiation monitors to determine if appropriate compensatory sampling and radiological analyses were conducted at the frequency specified in the Radiological Effluent Technical Specifications/Offsite Dose Calculation Manual. For compensatory sampling methods, the inspectors reviewed the licensees practices to determine if representative samples were obtained and if the licensee routinely relied on the use of compensatory sampling in lieu of adequate system maintenance or calibration of effluent monitors.

The inspectors reviewed surveillance test results for non-safety-related ventilation and gaseous discharge systems high efficiency particulate air and charcoal filtration to verify that the systems were operating within the specified acceptance criteria. In addition, the inspectors assessed the methodology the licensee used to determine the stack/vent flow rates to verify that the flow rates were consistent with the Radiological Effluent Technical Specifications/Offsite Dose Calculation Manual.

The inspectors reviewed the licensees program for identifying any normally non-radioactive systems that may have become radioactively contaminated to determine if evaluations (e.g. 10 CFR 50.59 evaluations) were performed per IE Bulletin 80-10.

The inspectors did not identify unidentified contaminated systems that may have been unmonitored discharge pathways to the environment.

The inspectors reviewed instrument maintenance and calibration records (i.e., both installed and counting room equipment) associated with effluent monitoring and reviewed quality control records for the radiation measurement instruments. The inspectors performed this review to identify any degraded equipment performance and to assess corrective actions, as applicable.

The inspectors reviewed the radionuclides that were included by the licensee in its effluent source term to determine if all applicable radionuclides were included (within detectability standards) in the licensees evaluation of effluents. The inspectors reviewed waste stream analyses (10 CFR Part 61 analyses) to determine if hard-to-detect radionuclides were also included in the source term analysis.

The inspectors reviewed a selection of monthly, quarterly, and annual dose calculations to ensure that the licensee had properly demonstrated compliance with 10 CFR Part 50, Appendix I, and Radiological Effluent Technical Specifications dose criteria.

The inspectors reviewed licensee records to identify any abnormal gaseous or liquid tank discharges (e.g., discharges resulting from misaligned valves, valve leak-by, etc) to determine if the licensee had implemented the required actions. The inspectors determined if abnormal discharges were assessed and reported as part of the Annual Radioactive Effluent Release Report consistent with Regulatory Guide 1.21.

The inspectors reviewed the licensees effluent sampling records (sampling locations, sample analyses results, flow rates, and source term) for radioactive liquid and gaseous effluents to verify that the licensees information satisfied the requirements of 10 CFR 20.1501.

This inspection constitutes one sample as defined by IP 71122.01-5.

b. Findings

No findings of significance were identified.

.3 Identification and Resolution of Problems

a. Inspection Scope

The inspectors reviewed the licensees self-assessments, audits, licensee event reports (LERs), and Special Reports related to the radioactive effluent treatment and monitoring program since the last inspection to determine if identified problems were entered into the CAP for resolution. The inspectors also assessed whether the licensee's self-assessment program was capable of identifying repetitive deficiencies or significant individual deficiencies in problem identification and resolution.

The inspectors reviewed corrective action reports from the radioactive effluent treatment and monitoring program since the previous inspection, interviewed staff, and reviewed documents to determine if the following activities were conducted in an effective and timely manner commensurate with their importance to safety and risk:

  • 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;
  • identification and implementation of effective corrective actions;
  • resolution of Non-Cited Violations (NCVs) tracked in the corrective action system;
  • implementation/consideration of risk significant operational experience feedback; and
  • ensuring problems were identified, characterized, prioritized, entered into a corrective action, and resolved.

This inspection constitutes one sample as defined by IP 71122.01-5.

b. Findings

No findings of significance were identified.

4OA2 Identification and Resolution of Problems

Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity, Emergency Preparedness, Public Radiation Safety, Occupational Radiation Safety, and Physical Protection

.1 Routine Review of Items Entered into the Corrective Action Program

a. Inspection Scope

As part of the various baseline inspection procedures discussed in previous sections of this report, the inspectors routinely reviewed issues during baseline inspection activities and plant status reviews to verify that they were being entered into the licensees CAP at an appropriate threshold, that adequate attention was being given to timely corrective actions, and that adverse trends were identified and addressed. Attributes reviewed included: the complete and accurate identification of the problem; that timeliness was commensurate with the safety significance; that evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent-of-condition reviews, and previous occurrences reviews were proper and adequate; and that the classification, prioritization, focus, and timeliness of corrective actions were commensurate with safety and sufficient to prevent recurrence of the issue.

Minor issues entered into the licensees CAP as a result of the inspectors observations are included in the attached List of Documents Reviewed.

These routine reviews for the identification and resolution of problems did not constitute any additional inspection samples. Instead, by procedure they were considered an integral part of the inspections performed during the quarter and documented in Section 1 of this report.

b. Findings

No findings of significance were identified.

.2 Daily Corrective Action Program Reviews

a. Inspection Scope

In order to assist with the identification of repetitive equipment failures and specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensees CAP. This review was accomplished through inspection of the stations daily condition report packages.

These daily reviews were performed by procedure as part of the inspectors daily plant status monitoring activities and, as such, did not constitute any separate inspection samples.

b. Findings

No findings of significance were identified.

.3 Semiannual Trend Review

a. Inspection Scope

The inspectors performed a review of the licensees CAP and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors review was focused on repetitive equipment issues, but also considered the results of daily inspector CAP item screening discussed in Section 4OA2.2 above, licensee trending efforts, and licensee human performance results. The inspectors review nominally considered the 6 month period of April 2009 through September 2009, although some examples expanded beyond those dates where the scope of the trend warranted.

The review also included issues documented outside the normal CAP such as 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 licensees CAP trending reports. Corrective actions associated with a sample of the issues identified in the licensees trending reports were reviewed for adequacy.

This review constituted a single semiannual trend inspection sample as defined in IP 71152-05.

Assessment and Observations Both the inspectors and licensee continue to identify issues regarding inadequate work preparation and execution. Although the licensee wrote Condition Report (CR) CR-PLP-2008-4383 to correct work preparation issues, this CR did not lead to improvement in work preparation and execution. The planning group initiated CR -PLP-2009-4906 in October 2009 for further evaluation of the issues. Several recent issues involved delays during work within limited TS allowed outage times. The inspectors determined that the new corrective actions were better focused on the areas needing improvement and that appropriate levels of management were now engaged to ensure work preparation and execution improvement occurs.

b. Findings

No findings of significance were identified.

.4 Annual Sample: Review of Operator Workarounds

a. Inspection Scope

The inspectors evaluated the licensees implementation of their process used to identify, document, track, and resolve operational challenges. Inspection activities included, but were not limited to, a review of the cumulative effects of the Operator Workarounds (OWAs) on system availability and the potential for improper operation of the system, for potential impacts on multiple systems, and on the ability of operators to respond to plant transients or accidents. Additionally, the inspectors observed operators performing rounds to detect the presence of undocumented burdens and workarounds.

The inspectors performed a review of the cumulative effects of OWAs. The documents listed in the Attachment were reviewed to accomplish the objectives of the inspection procedure. The inspectors reviewed both current and historical operational challenge records to determine whether the licensee was identifying operator challenges at an appropriate threshold, had entered them into their CAP and proposed or implemented appropriate and timely corrective actions which addressed each issue. Reviews were conducted to determine if any operator challenge could increase the possibility of an Initiating Event, if the challenge was contrary to training, required a change from long-standing operational practices, or created the potential for inappropriate compensatory actions. Additionally, all temporary modifications were reviewed to identify any potential effect on the functionality of Mitigating Systems, impaired access to equipment, or required equipment uses for which the equipment was not designed.

Daily plant and equipment status logs, degraded instrument logs, and operator aids or tools being used to compensate for material deficiencies were also assessed to identify any potential sources of unidentified operator workarounds.

This review constituted one operator workaround annual inspection sample as defined in IP 71152-05.

b. Findings

No findings of significance were identified.

.5 Selected Issue Followup Inspection: Substantive Cross-Cutting Issue: Procedures

a. Inspection Scope

In the mid-cycle performance review, the licensee had a substantive cross-cutting issue regarding quality of procedures and labeling held open. The inspectors reviewed the licensees progress in addressing the substantive cross-cutting issues to determine if the licensees actions provided confidence that the licensee would resolve the substantive cross-cutting issue. The inspectors reviewed the licensees reports related to the procedure improvement effort. The licensee has made progress with completion of procedure screening criteria, screening 60 procedures and developing methods to track procedure revisions. The inspectors reviewed three procedures that were subject to the screening criteria. The inspectors also walked down portions of two of the procedures.

The inspectors noted many instances where component labels were not identical to nomenclature in the procedure. The inspectors also identified other errors in the reviewed procedures that should have been identified using the checklist developed to ensure procedure quality. The licensee documented these issues in the CAP. No deficiencies were of more than minor significance. However, over the past two quarters, there have not been significant performance deficiencies related to procedure quality.

With the increase in emphasis in documenting procedure deficiencies, development of a procedure improvement infrastructure and increase in management awareness of procedure quality issues, the licensee has established a level of confidence that they will resolve the issue with procedure quality.

This review constituted one in-depth problem identification and resolution sample as defined in IP 71152-05.

b. Findings

No findings of significance were identified.

.6 Selected Issue Followup Inspection: Substantive Cross-Cutting Issue: Planning

a. Inspection Scope

In the mid-cycle performance review, the licensee had a substantive cross-cutting issue regarding quality of work planning. The inspectors reviewed the licensees progress in addressing the substantive cross-cutting issue to determine if the licensees actions provided confidence that the licensee would resolve the substantive cross-cutting issue.

The apparent cause evaluation that was performed by the licensee determined that a lack of familiarity and practice with the change management process led to ineffective use of change management as a human performance tool. The inspectors reviewed the findings that contributed to the cross-cutting issue, recent issues dealing with work planning (outlined in the Semi-Annual Trend Review description above), and corrective actions taken. The inspectors determined that while more consistent use and awareness of the change management policy would reasonably reduce the likelihood of planning issues in risk significant plant changes and activities, it may not be adequate to address the recent issues in work planning discovered during more routine plant maintenance evolutions. The licensee is taking action to address these items not related to change management. The inspectors also noted an increase in the utilization of change management tools by site personnel during the review, and there were no findings related to the planning cross-cutting aspect for the last two quarters. Combined with actions being taken separately to address the recent trend in planning issues described in the Semi-Annual Trend Review, the inspectors concluded the licensee has identified appropriate corrective actions and has made progress with implementation of the corrective actions.

This review constituted one in-depth problem identification and resolution sample as defined in IP 71152-05.

b. Findings

No findings of significance were identified.

.7 Selected Issue Follow-up Inspection: Failure of Service Water Pump P-7C Coupling

a. Inspection Scope

The inspectors completed one inspection sample regarding problem identification and resolution by conducting in-depth review of the following corrective action records:

  • Root Cause Evaluation Report, SW Pump P-7C Failure to Provide Discharge Pressure.

The inspectors evaluated the licensee's actions in accordance with the performance attributes identified in IP 71152. Specifically, the inspectors reviewed licensee corrective action records to determine if:

  • the problems were accurately identified;
  • system operability and reportability were adequately ascertained;
  • the extent of condition and generic implications were appropriately addressed;
  • classification and prioritization of problem was commensurate with safety significance;
  • root and contributing causes were identified;
  • corrective actions were appropriately focused to correct the problem; and
  • timely corrective actions were completed or proposed commensurate with the safety significance of the issues.

The inspectors also reviewed other licensee records which included: Section 9.1 Service Water System of the Palisades UFSAR, TS 3.7.8; and records related to the procurement and fabrication of the SW pump P-7C line shaft couplings.

b. Findings

No findings of significance were identified.

4OA3 Followup of Events and Notices of Enforcement Discretion

.1 Notice of Enforcement Discretion (NOED) for Repair to Service Water Pump P-7C

a. Inspection Scope

The licensee submitted an oral request for enforcement discretion for TS 3.7.8, required action A.1, B.1, and B.2. on October 1, 2009. The licensee requested discretion in order to complete repairs on the P-7C service water pump which had a failed coupling. The NRC granted approval per telecom on October 1 with a follow-up written request on October 5. After the NRC granted verbal approval of the NOED, the inspectors verified the licensee performed mitigating actions committed to in the NOED. However, the licensee restored the pump to an operable status without entering the period of enforcement discretion. On October 6, 2009, the licensee informed the inspectors that the commitments related to independent verification of the hardness of the couplings were not completed. In accordance with IMC Part 9900, the inspectors opened URI 05000255/2009005-01 to track inspection of the NOED activities. Because some commitments were not completed and the information potentially impacted the regulatory process, URI 05000255/2009005-01 will remain open pending determination of significance.

Prior to approval for granting the NOED, the inspectors (from the site, headquarters and the region) reviewed the licensees basis for the NOED in accordance with NRC Manual Chapter 9900, Technical Guidance, Operations- Notice of Enforcement Discretion.

The inspectors also reviewed the scheduled work activities, environmental conditions, compensatory actions planned, and the sites readiness to implement the NOED. The review of these items is also documented in the NRC approval letter for NOED 09-3-002 dated October 7, 2009.

This event follow-up review constituted one sample(s) as defined in IP 71153-05

b. Findings

Unresolved Item 20090005-01 NOED for Repair to Service Water Pump P-7C

Introduction:

During the request for a NOED, the licensee committed to performing an independent verification of hardness on each pump coupling. Subsequently, the licensee informed the inspectors that an independent verification of hardness had not been completed on each coupling.

Description:

On September 29, while at 100 percent power, the upper shaft coupling for the P-7C service water pump failed, rendering the pump inoperable. The licensee determined that the pump would not be operable prior to expiration of the 72 completion time. On October 1, the licensee verbally requested enforcement discretion to avoid a shutdown.

During the request, the licensee informed the NRC that the failed coupling likely failed due to improper heat treatment of the coupling that resulted in high out of specification hardness. Since the testing requirements in place should have identified the out of specification hardness, the licensee committed to independently testing each coupling for hardness prior to installation. The licensee reiterated that each coupling would be independently hardness tested prior to installation in the written NOED request.

Subsequently, the licensee informed the NRC that the independent hardness test had not been performed. The licensee wrote a CR to document this item and evaluated that the P-7C was operable. The independent hardness test could not be performed with the pump re-assembled. The inspectors evaluated the licensees assessment of operability of the P-7C pump using the guidelines of 71111.15. The inspectors concluded there was reasonable assurance the couplings were acceptable.

Pending determination on whether a violation occurred, URI 05000255/2009005-01 will remain open.

.2 (Closed) Licensee Event Rerport 2008-004-00, Noncompliance with Technical

Specification 4.3.1.1.b This event, which the licensee identified on July 15, 2008, concerned significant degradation of the neutron-absorbing material in Region-I of the spent fuel pool racks.

The degradation led to violation of TS 4.3.1.1.b for an extended period of time. Further analysis to quantify the degradation continued throughout 2008 and into 2009. NRC review of the issue resulted in a preliminary white inspection finding which was communicated to the licensee via choice letter dated December 9, 2009. Inspection Report 2009008 discusses the finding. A final White finding was issued January 20, 2010 (Inspection Report 2010007). No additional safety concerns were identified.

Documents reviewed as part of this inspection are listed in the attachment. This LER is closed.

This event followup review constituted one sample as defined in IP 71153-05.

4OA5 Other Activities

.1 (Opened) Unresolved Item 05000255/2009005-03, Adequacy of Building Lightning

Protection a. Introduction During the previous inspection period, the inspectors reviewed lightning protection adequacy of risk significant structures. The inspectors recognized that the auxiliary building does not have lightning rods installed and requested the licensees basis for determining that the auxiliary building had adequate protection.

b. Description In report No. 05000255/2009-004, the inspectors reviewed site strategies to counter the effects of lightning strikes. The need to protect structures, systems, and components important to safety from the effects of natural phenomena (to include lightning) is discussed in the UFSAR and in the plants response to Fire Protection Branch Technical Position APCSB 9.5-1. As part of the inspection, the inspectors performed a walkdown of various rooftop areas. Based on this review, the inspectors questioned if air terminals, or lightning rods, were required on the auxiliary building. The licensee responded that the nearby (and taller) containment structure, which has four air terminals, adequately protected the auxiliary building. Subsequent to the issuance of report No. 05000255/2009-004, ongoing discussions with the licensee revealed that National Fire Protection Association (NFPA) codes did not support the licensee position that containment structure would provide protection to the auxiliary building. Therefore, the inspectors concluded that the basis for the acceptability of the lightning protection of the auxiliary building is not available and additional information is needed to determine the adequacy of the current configuration. The licensee has entered the issue into their corrective action program as CR-PLP-2009-5419, which contains a corrective action to perform an assessment of lightning protection systems on site. Pending the licensees evaluation of the condition and a review of the evaluation by the inspectors, this issue will be considered a URI. The assessment is currently scheduled to start during the next inspection period, therefore, the issue will be entered as URI 05000255/2009005-003, Adequacy of Auxiliary Building Lightning Protection.

.2 Quarterly Resident Inspector Observations of Security Personnel and Activities

a. Inspection Scope

During the inspection period, the inspectors conducted observations of security force personnel and activities to ensure that the activities were consistent with licensee security procedures and regulatory requirements relating to nuclear plant security.

These observations took place during both normal and off-normal plant working hours.

These quarterly resident inspector observations of security force personnel and activities did not constitute any additional inspection samples. Rather, they were considered an integral part of the inspectors' normal plant status review and inspection activities.

b. Findings

No findings of significance were identified.

.3 (Closed) NRC Temporary Instruction 2515/175 Emergency Response Organization,

Drill/Exercise Performance Indicator, Program Review The inspectors performed Temporary Instruction 2515/175, ensured the completeness of 1 and then forwarded the data to NRC, Headquarters.

.4 Operational Testing of an Independent Spent Fuel Storage Facility Installation at

Operating Plants (60855.1)

a. Inspection Scope

A number of questions were raised during several public meetings pertaining to Sierra Nuclear Ventilated Storage Cask No. 24 (VSC-24) Multi-Assembly Sealed Basket Number 4 (MSB No. 4) which was initially loaded with spent fuel at the Palisades plant in 1994. These questions pertained to the adequacy of MSB No. 4 to safely store fuel due to potentially flawed welds, the licensees commitment to unload the cask after revisions to the unloading procedures were revised, and cask access on the pad.

Several of the inquiries during the public meetings questioned why MSB No. 4 had not been unloaded since 1994 after there were weld indications identified on the cask and after the licensee reviewed its unloading procedure and determined the procedures to be adequate. Reviews by licensee and vendor inspectors of radiography test inspection films identified indications including two crack-like indications and one slag-like indication (three indications) in longitudinal seam weld of MSB No. 4. The licensee verified that the Certificate of Compliance and the VSC-24 TSs requirements for the vacuum and helium pressures inside the MSB were met and remained constant over a specified period of time providing reasonable assurance that the flaws did not penetrate the wall of the basket. In lieu of repair, the licensee performed an engineering evaluation of the three indications with respect to the operability of MSB No. 4 and determined that despite the flaws, the pressure and containment functions were maintained in accordance with the design basis and that the cask was structurally sound. In addition, the licensee performed radiation surveys which indicated that there was no change in radiation levels that would indicate fission gas protrusion through the basket wall.

After the inspectors independently reviewed the licensees commitments to the American Society of Mechanical Engineers codes, they confirmed the licensees conclusion that post loading reviews of the non-destructive testing records by the licensee revealed weld indications in MSB No. 4. The NRC, Region III, Division of Nuclear Materials Safety staff issued a Technical Assistance Request (TAR) to the Nuclear Materials Safety and Safeguards Division of Spent Fuel Storage and Transportation (SFST) to evaluate the licensees engineering analysis of the three indications in one of the confinement boundary welds to evaluate the structural integrity for interim and continued operability of MSB No. 4.

The SFST staff evaluated the structural integrity of MSB No. 4 by reviewing the licensees flaw propagation and stability analysis, which they performed in lieu of repair.

The origin and cause of the indications were not certain. The NRC staff determined that the fracture mechanics (flaw tolerance) analysis provided by the licensee demonstrated the ability of MSB No. 4 to perform its intended function for the duration of the casks 50-year design life. The calculations confirmed that the cask shell material demonstrated a considerable flaw tolerance and calculations indicated that the three indications will remain static during in-service operation and will not propagate as a result of any design basis normal or off-normal event. Thus MSB No. 4 does not pose an increased radiological impact to the public or environment. The NRC staff has reasonable assurance, through verifiable data in the licensees engineering analyses, that MSB No. 4 is capable to safety operate despite the three indications. After identification of the three indications, the licensee performed daily contamination and dose rate surveys on the VSCs and the increased radiological monitoring of the cask and storage pad did not indicate any unusual dose rates or contamination. Based on this data, the licensee now performs the contamination and dose rate surveys on a quarterly basis. The TAR provides the details of the NRCs evaluation of the operability of MSB No. 4 (ADAMS ML100210186).

In 1994 correspondence with the NRC, the licensee (Consumers Power Company at the time) informed the NRC of the three indications and of their intent to unload the fuel after resolution of technical issues with unloading procedures. In preparation for the unloading of MSB No. 4, the licensee initiated a detailed review of the unloading procedure in 1994 and identified several technical issues associated with the unloading procedures that needed to be resolved prior to unloading of MSB No. 4. A revision of the unloading procedure was subsequently developed (Revision 1 issued in June 1995).

The NRC reviewed the procedure and determined that the licensee would be able to safely unload the cask as documented in Inspection Report Number 05000255/1996014.

However, in 1997, the licensee informed the NRC of the decision not to unload MSB No. 4 until it could be loaded into a certified storage and transportation cask in preparation for permanent disposal. This strategy would minimize the risk of reloading MSB No. 4 twice, first to a storage only container and then to a storage and transportation cask. Thus the NRC staff acknowledged that the licensee initially planned to unload MSB No. 4 after a thorough technical review of the unloading procedures was performed. However, to minimize the risk of reloading MSB No. 4 twice, the licensee eventually decided to defer reload of MSB No. 4 until a certified storage and transportation cask was available.

The third concern expressed at the public meetings pertained to cask movement on the pad and the assumption that the storage configuration of the casks on the pad prevents movement of casks in the event of an emergency that requires a cask to be returned to the spent fuel pool for unloading. The licensee maintains procedures and equipment that is needed to unload a cask. In order to unload a cask, the licensee may need to move other casks due to the configuration of the casks and the size of the pad. The licensee has factored this into its planning and has controls in place to allow for the repositioning of a cask. There is also additional space on the pad where casks can be temporarily placed. Therefore, the NRC inspectors concluded that the licensee has procedures in place which would allow access to any cask on the pad in the unlikely situation where a cask would need to be unloaded.

b. Findings

No findings of significance were identified.
