SUBJECT:
PALISADES NUCLEAR GENERATING PLANT NRC INTEGRATED INSPECTION REPORT 50-255/03-02
Dear Mr. Cooper:
On March 31, 2003, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Palisades Nuclear Generating Plant. The enclosed report documents the inspection findings which were discussed on April 11, 2003, with yourself and other members of your staff.
The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license.
The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
Based on the results of this inspection, three findings of very low safety significance (Green)
were identified which involved violations of NRC requirements. However, because of their very low safety significance and because the issues were entered into your corrective action program, the NRC is treating these issues as Non-Cited Violations in accordance with Section VI.A.1 of the NRCs Enforcement Policy.
If you contest these Non-Cited Violations, you should provide a response with a basis for your denial, within 30 days of the date of this inspection report, 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, 801 Warrenville Road, Lisle, IL 60532-4351; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the Resident Inspector Office at the Palisades facility.
Since the terrorist attacks on September 11, 2001, the NRC has issued two Orders (dated February 25, 2002, and January 7, 2003) and several threat advisories to licensees of commercial power reactors to strengthen licensee capabilities, improve security force readiness, and enhance access authorization. The NRC also issued Temporary Instruction 2515/148 on August 28, 2002, that provided guidance to inspectors to audit and inspect licensee implementation of the interim compensatory measures (ICMs) required by the February 25th Order. Phase 1 of TI 2515/148 was completed at all commercial nuclear power plants during calendar year (CY) 02, and the remaining inspections are scheduled for completion in CY 03. Additionally, table-top security drills were conducted at several licensees to evaluate the impact of expanded adversary characteristics and the ICMs on licensee protection and mitigative strategies. Information gained and discrepancies identified during the audits and drills were reviewed and dispositioned by the Office of Nuclear Security and Incident Response. For CY 03, the NRC will continue to monitor overall safeguards and security controls, conduct inspections, and resume force-on-force exercises at selected power plants.
Should threat conditions change, the NRC may issue additional Orders, advisories, and temporary instructions to ensure adequate safety is being maintained at all commercial power reactors.
In accordance with 10 CFR 2.790 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

SUMMARY OF FINDINGS
IR 05000255/03-02; Nuclear Management Company, LLC; 12/29/2002 - 03/31/2003; Palisades
Nuclear Generating Plant; Equipment Alignment; Surveillance Testing; Event Followup.
This report covers a 3-month period of baseline resident inspections, a physical protection inspection, and a radiation protection inspection. The inspections were conducted by resident inspectors and a regional based physical security inspector. Three Green findings with associated Non-Cited Violations (NCVs) were identified during the inspection. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter 0609, Significance Determination Process, (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 3, dated July 2000.
A.
Inspector Identified and Self-Revealing Findings
Cornerstone: Mitigating Systems
C
- Green.
The inspectors identified a finding for the failure to implement adequate corrective actions to prevent recurrence of issues associated with the construction of seismic scaffolding near safety-related systems.
This finding was more than minor because if left uncorrected it would become a more significant safety concern in that inadequately constructed scaffold could affect the availability of mitigating systems during a seismic event. The finding was of very low safety significance because the finding did not screen as potentially risk significant due to a seismic initiating event and did not involve the total loss of any safety function that contributes to core damage accident sequences initiated by seismic events. The inspectors also determined that this finding represented continued human performance deficiencies in the construction of seismic scaffolding near safety-related systems. A Non-Cited Violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, was identified. (Section 1R04.1)
Cornerstone: Barrier Integrity
C
- Green.
The inspectors identified a finding for the failure to ensure that testing of the fuel handling area ventilation system was performed in accordance with test procedures which incorporated the appropriate requirements and acceptance limits specified in Technical Specification 5.5.10, Ventilation Filter Testing Program.
This finding was more than minor because if left uncorrected it would become a more significant safety concern in that the radiological barrier function provided by the fuel handling area ventilation system was degraded and was not being tested adequately. The finding was of very low safety significance because the finding represented a degradation of only the radiological barrier function provided for the spent fuel pool. The inspectors also determined that this finding was a result of human performance deficiencies related to developing and implementing the Technical Specification surveillance. A Non-Cited Violation of 10 CFR 50, Appendix B, Criterion XI, Test Control, was identified.
(Section 1R22.1)
C
- Green.
The inspectors determined that a self-revealed finding was associated with the failure to restore an inoperable channel of containment hydrogen monitoring within the allowed outage times specified in Technical Specification Action Statements 3.3.7.A and 3.3.7.D.
The finding was more than minor because the barrier integrity cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events was affected. The finding was determined to be of very low safety significance after a Region III Senior Reactor Analyst, in conjunction with the inspectors, performed a SDP Phase 3 assessment. Utilizing NUREG-1675, Basis Document for Large Early Release Frequency Significance Determination Process, the analyst determined that the significance threshold for large early release frequency of 100 volume percent per day leak rate from containment would not be exceeded.
The inspectors also noted that this finding was attributable to a latent human performance deficiency which occurred during the April 2001 refueling outage, but was self-revealed in December 2002. A Non-Cited Violation of Technical Specification Section 3.3.7 was identified. (Section 4OA3.1)
B.
Licensee Identified Findings One violation of very low safety significance, which was identified by the licensee was reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensees corrective action program. The violation and corrective action tracking numbers are listed in Section 4OA7 of this report.
REPORT DETAILS
A list of documents reviewed within each inspection area is included at the end of the report.
Summary of Plant Status
The plant was at full power for the majority of the inspection period with the following two exceptions:
C During an Unusual Event for an unexplained lowering level in the service water pump bays on February 16, 2003, operators reduced power to 89 percent to stabilize the balance of plant equipment. The lowering level in the service water pump bays was subsequently determined to have been caused by ice forming on the intake structure in Lake Michigan which reduced flow to the pump bays. On February 21, 2003, power was again raised to full power after licensee personnel determined that no ice remained and that no major damage had occurred to the intake structure.
C On March 16, 2003, the plant was shut down to begin a scheduled refueling outage which was ongoing when the inspection period ended.

.1 Inadequate Corrective Actions for Seismic Scaffolding Built Near Safety-Related
Equipment (71111.04S)
a. Inspection Scope
During walkdowns of the auxiliary feedwater system, the inspectors assessed the condition of seismic scaffolding built near safety-related equipment. The inspectors verified the scaffolds were built in accordance with the licensees procedures and reviewed the licensees corrective actions taken for scaffolding issues previously identified by the NRC.
b. Findings
Introduction The inspectors identified a finding of very low safety significance (Green) that is being treated as a Non-Cited Violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, for the failure to implement adequate corrective actions to prevent recurrence for issues associated with the construction of seismic scaffolding near safety-related systems.
Description On February 27, 2003, the inspectors identified that scaffolding erected near safety-related equipment in the west engineering safeguards room did not meet the minimum spacing requirements from the safety-related backup suction piping to Auxiliary Feedwater Pump P-8C. The inspectors also noted that the scaffolding did not have the required engineering evaluation and approval to be built in this manner. Step 5.5.3a of Procedure MSM-M-43, Scaffolding, required, in part, that a minimum separation of 1-inch in all directions shall be maintained between braced scaffolding and safety-related equipment. Step 5.5.7 of Procedure MSM-M-43 required, in part, that design engineering provide justification and approval for deviating from the procedure requirements.
The licensee rebuilt the scaffold and initiated Condition Report CAP033667, Seismic Scaffold Does Not Meet Installed Plant Equipment Separation Requirement. The licensees immediate corrective actions included a temporary suspension of scaffold erection activities, stand-down and retraining of scaffold builders and supervisors, and an extent of condition walkdown to identify other potentially deficient scaffold installations. During the extent of condition walkdown, the licensee identified and corrected several additional seismic scaffolds which were not built in accordance with Procedure MSM-M-43.
On March 3, 2003, the inspectors again identified additional seismic scaffolding erected near safety-related equipment in the component cooling water heat exchanger room which did not meet the requirements of Procedure MSM-M-43. The licensee rebuilt the scaffold, initiated a Condition Report, and again took additional immediate corrective actions.
The inspectors reviewed NRC-identified scaffold control issues which had occurred in the past 2 years to determine if there had been prior opportunities to address seismic scaffolding construction deficiencies. In February and March 2001, just prior to the start of the 2001 Refueling Outage, the NRC issued a Green finding and associated Non-Cited Violation (NCV) 50-255/01-06-02, for several examples of the licensees failure to adequately implement procedural requirements for the control of seismic scaffolding in the vicinity of safety-related equipment. The licensees root cause analysis for this condition adverse to quality determined that the site lacked a programmatic method to control scaffold design, erection, inspection and approval. The licensee completed all corrective actions to prevent recurrence for this finding on October 15, 2002.
On December 17, 2002, the NRC documented a Green finding and associated NCV 50-255/02-10-01, for several examples of the licensees failure to adequately implement procedural requirements for the control of seismic scaffolding in the vicinity of safety-related equipment. Based on the identification of repetitive failures in the past 2 years to adequately control seismic scaffolding construction the inspectors concluded that previous remedial and corrective actions to prevent recurrence were not effective.
The inspectors determined that the failure to implement adequate corrective actions to prevent recurrence of issues associated with the construction of seismic scaffolding near safety-related systems was a licensee performance deficiency warranting a significance evaluation.
Analysis The inspectors determined that this finding was greater than minor in accordance with Inspection Manual Chapter (IMC) 0612, Power Reactor Inspection Reports, Appendix B, Issue Disposition Screening, issued on February 21, 2003, in that the finding would become a more significant safety concern if left uncorrected.
Specifically, scaffolding installed in the vicinity of safety-related equipment could fail during a seismic event and result in damage to mitigating equipment. Consequently, continued human performance deficiencies in the construction of scaffolding near safety-related systems could affect the availability of mitigating systems that respond during seismic events, and if left uncorrected would become a more significant safety concern.
The inspectors evaluated the finding using Manual Chapter 0609, Significance Determination Process, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations, Phase 1 screening, and determined that the finding:
- was not a design or qualification deficiency;
- did not represent an actual loss of safety function of a system;
- did not represent an actual loss of a safety function of a single train for greater than Technical Specification outage time;
- did not represent an actual loss of a safety function of one or more Non-Technical Specification trains of equipment;
- did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event; C
did not involve the total loss of any safety function that contributed to core damage accident sequences initiated by seismic events; and C
did not involve the loss or degradation of equipment or function designed to mitigate a seismic initiating event.
Therefore, the finding was determined to be of very low safety significance (Green).
Enforcement 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, requires, in part, that in the case of significant conditions adverse to quality, measures shall assure that the cause of the condition is determined and corrective action taken to preclude repetition. Contrary to this, the licensees corrective actions to preclude repetitive human performance deficiencies during the construction of seismic scaffolding near safety-related systems have not been effective as evidenced by the following:
- NCV 50-255/01-06-02 issued on April 19, 2001, for several examples of the failure to adequately implement procedural requirements for the control of seismic scaffolding in the vicinity of safety-related equipment;
- NCV 50-255/02-10-01 issued on December 17, 2002, for the failure to adequately implement procedural requirements for the control of scaffolding in the vicinity of safety-related equipment; and
- continued examples of the failure to adequately implement requirements for the construction of seismic scaffolding near safety-related equipment in February and March 2003.
This violation is associated with an inspector identified finding that is characterized by the significance determination process as having very low safety significance (Green)and is being treated as a Non-Cited Violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, consistent with Section VI.A.1 of the NRC Enforcement Policy.
(NCV 50-255/03-02-01)
This issue was entered in the licensees corrective action program as Condition Reports CAP033667, Seismic Scaffold Does Not Meet Installed Plant Equipment Separation Requirement, and CAP033744, Seismic Scaffold That Did Not Appear to Meet Equipment Separation Requirement.

The inspectors also reviewed the documented test data for the Technical Specification surveillance test procedures and the associated basis documents to verify that testing acceptance criteria were satisfied.
In addition, the inspectors reviewed applicable portions of Technical Specifications, the Updated Final Safety Analysis Report, and Design Basis Documents to verify that the surveillance tests adequately demonstrated that system components could perform designated safety functions.
Further, the inspectors reviewed selected condition reports regarding the fuel handling ventilation surveillance testing activities to verify that conditions adverse to quality were appropriately entered into the licensees corrective action program and that identified corrective actions were reasonable and had been implemented in a manner commensurate with significance.
b. Findings
Introduction The inspectors identified a Green finding that is being treated as a Non-Cited Violation of 10 CFR 50, Appendix B, Criterion XI, Test Control, for the failure to ensure that testing of the fuel handling area ventilation system was performed in accordance with test procedures which incorporated the appropriate requirements and acceptance limits specified in Technical Specification 5.5.10, Ventilation Filter Testing Program.
Description The inspectors reviewed and observed the licensee perform Procedure RT-85C, Technical Specification Surveillance Procedure - Fuel Handling Area Ventilation System Filter Testing, on March 3, 2003. The purpose of the surveillance test was to demonstrate operability of the Fuel Handling Ventilation System in accordance with the Surveillance Requirements of Technical Specification 3.7.12, Fuel Handling Area Ventilation System, and the Ventilation Filter Testing Program specified in Section 5.5.10 of the Technical Specifications. The inspectors noted that the surveillance test was performed with the use of licensee system engineers concurrent with a contractor and contractor specific procedures for certain portions of the test.
The inspectors identified numerous issues associated with the testing of the Fuel Handling Ventilation System which included:
- (1) human performance issues by the licensee and contractor personnel associated with performing the test in accordance with the test procedures;
- (2) test procedures which did not incorporate all the requirements and acceptance limits contained in Regulatory Guide 1.52, Revision 2 and the ASME Standard N-510-1989, as required;
- (3) lack of contractor oversight by licensee personnel during portions of the test to assure that the testing was performed as required; and
- (4) inadequate material condition of specific portions of the Fuel Handling Ventilation System. Consequently, the inspectors concluded that the surveillances performed on the fuel handling ventilation system were inadequate. Some specific issues the inspectors identified included the following:
C Several instances where procedure steps were not implemented as prescribed and were performed out of sequence for the Continuous Use procedures; C
Sampling of the filter testing challenge gas downstream of the charcoal and high efficiency particulate air (HEPA) filters was performed in a manner that air outside the filter housings diluted the downstream filter test results; C
Upon completion of the required visual inspection of the Fuel Handling Ventilation System by the licensee and contractor as satisfactory with minor exceptions, the inspectors identified the following issues:
- a previously unidentified through-wall tear on the expansion joint for the suction of Ventilation Fan V-8B;
- a tear and hole on the east side of the exhaust ductwork from Ventilation Fan V-8B; and
- a hole on the southwest corner of the exhaust ductwork from Ventilation Fan V-8B.
The holes and tears identified by the inspectors constituted bypass paths around the Fuel Handling Ventilation System to the atmosphere.
C Contractors procedure utilized to perform the HEPA and charcoal filter efficiency tests was written to ASME Standard N-510-1975 as opposed to ASME Standard N-510-1989 which was required by Technical Specifications; and C
No evidence that an air-aerosol mixing uniformity test had been performed as required by ASME Standard N-510-1989 as a prerequisite for performing HEPA and charcoal filter efficiency tests. In addition, licensee personnel could not identify an exemption from the Office of Nuclear Reactor Regulation for not having to perform the test.
Licensee personnel subsequently initiated condition reports for the inspector identified issues which were entered into the licensees corrective action program. In addition, condition reports were generated for additional deficiencies that were identified by licensee personnel who reviewed the circumstances surrounding the inspector identified issues associated with this testing. As a result, licensee personnel subsequently revised the test procedures and re-performed the tests, including the air-aerosol mixing uniformity test, to demonstrate that the Fuel Handling Ventilation System was operable for refueling operations.
The inspectors determined that the failure to ensure that testing was performed for the Fuel Handling Ventilation System in accordance with written test procedures which incorporated the applicable requirements and acceptance limits was a licensee performance deficiency warranting a significance evaluation.
Analysis The inspectors determined that this finding was greater than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Disposition Screening, issued on February 21, 2003, because the finding affected the barrier integrity cornerstone and if left uncorrected would become a more significant safety concern.
Specifically, human performance deficiencies identified by the inspectors resulted in the failure to ensure that the fuel handling area ventilation system testing was performed in accordance with test procedures which incorporated the appropriate requirements and acceptance limits. Consequently, the radiological barrier function provided by the fuel handling area ventilation system was degraded and was not being tested adequately, and if left uncorrected would become a more significant safety concern.
The inspectors evaluated the finding using Manual Chapter 0609, Significance Determination Process, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations, Phase 1 screening. The inspectors determined that although the barrier integrity cornerstone was adversely impacted, the finding represented a degradation of only the radiological barrier function provided for the spent fuel pool.
Therefore, the finding was determined to be of very low safety significance (Green).
Enforcement 10 CFR 50, Appendix B, Criterion XI, Test Control, requires, in part, that a test program shall be established to assure that all testing required to demonstrate that structures, systems and components will perform satisfactorily in service is identified and performed in accordance with written test procedures which incorporate the requirements and acceptance limits contained in applicable design documents. Contrary to this, on March 3, 2003, the licensee failed to assure that testing was performed in accordance with the written test procedures for the Fuel Handling Ventilation System. In addition, the licensee failed to assure that the written test procedures incorporated the requirements and acceptance limits as required by Technical Specification 5.5.10, Ventilation Filter Testing Program.
This violation is associated with an inspector identified finding that is characterized by the significance determination process as having very low safety significance (Green)and is being treated as a Non-Cited Violation of 10 CFR 50, Appendix B, Criterion XI, Test Control, consistent with Section VI.A.1 of the NRC Enforcement Policy.

4OA3 Event Follow-up
.1 (Closed) Licensee Event Report (LER)02-003, Inoperable Containment Hydrogen
Monitors
a. Inspection Scope
The inspectors reviewed Licensee Event Report 02-003, Inoperable Containment Hydrogen Monitors, to verify that the event was accurately described, to determine if any violations of NRC requirements had occurred and to assess the appropriateness of identified corrective actions.
b. Findings
Introduction The inspectors determined that a self-revealed Green finding was associated with a Non-Cited Violation of Technical Specification Section 3.3.7 for the failure to restore an inoperable channel of containment hydrogen monitoring within the allowed outage times contained in Technical Specification Action Statements 3.3.7.A and 3.3.7.D.
Description On December 21, 2002, during the performance of a surveillance test, the licensee discovered that the pipe caps for two test taps on the right channel containment hydrogen monitor instrument lines were not installed. The uninstalled pipe caps prevented the surveillance from being completed satisfactorily which prompted licensee personnel to identify the problem.
The containment hydrogen monitor is utilized to sample the containment atmosphere for hydrogen concentrations following a design basis accident to determine if additional actions are needed to abate high hydrogen concentrations. The two test taps were located between the outermost containment isolation valve and the next control valve on the hydrogen monitor instrument line. Therefore, if the right channel hydrogen monitor was placed in service following an accident then the following would have occurred:
C The first test tap without a pipe cap would result in a hydrogen sample being returned to the auxiliary building instead of being returned to containment; C
The second test tap without a pipe cap could open a path from the auxiliary building atmosphere to the hydrogen monitor sample pump such that when containment was at or below auxiliary building pressure, the hydrogen sample would be diluted and the hydrogen monitor would display a value less than the actual hydrogen concentration in containment; and C
Following an accident, if containment pressure was greater than auxiliary building pressure then both taps could be pressurized by containment atmosphere resulting in a release to the auxiliary building.
Licensee personnel completed a root cause evaluation for this event and concluded that the pipe caps were not placed back on the test taps after the Containment Integrated Leak Rate Test, Test RT-36, was last performed in the April 2001 refueling outage.
Licensee personnel also concluded that the failure to reinstall the test tap pipe caps was attributable to human performance failures involving inadequacies in procedure compliance and independent verification policies when completing prescribed procedure actions. The inspectors determined that the conclusions were reasonable.
The inspectors determined that the failure to ensure that the right channel hydrogen monitoring system was aligned properly after the system was restored from testing during the 2001 refueling outage was a self-revealed licensee performance deficiency which warranted a significance evaluation.
Analysis The inspectors determined that this finding was greater than minor in accordance with IMC 0612, Power Reactor Inspection Reports, Appendix B, Issue Disposition Screening, issued on February 21, 2003. The finding dealt with maintaining the functionality of containment and was related to the barrier integrity cornerstone attribute regarding configuration control. The cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events was affected.
Specifically, the human performance deficiencies which resulted in the failure to ensure that the pipe caps were installed after testing was completed in April 2001 resulted in the right channel hydrogen monitor being inoperable. Consequently, the hydrogen monitor was incapable of measuring a representative hydrogen concentration in the containment atmosphere following an accident. In addition, the uninstalled pipe caps also represented a potential radiological release path if the hydrogen monitor had been placed in service following an accident.
The inspectors evaluated the finding using Manual Chapter 0609, Significance Determination Process, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations, Phase 1 screening. The inspectors determined that the finding represented an actual open pathway in the physical integrity of reactor containment which required additional analysis using Manual Chapter 0609, Appendix H, Containment Integrity SDP. Utilizing Appendix H, the inspectors determined the finding was potentially risk significant.
A Region III Senior Reactor Analyst in conjunction with the inspectors performed a Phase 3 assessment. Utilizing NUREG-1675, Basis Document for Large Early Release Frequency (LERF) Significance Determination Process (SDP), the analyst determined that a containment leak rate of 100 volume percent per day constitutes the threshold for LERF significance. The 100 volume percent per day leakage rate is approximately equivalent to an opening size in the containment of 2.5 to 3 inches in diameter for Pressurized Water Reactors with large dry containments, thus the significance of this finding was found to be very low as the actual combined open pathways from both test taps was less than 0.5 inches in diameter.
Therefore, the finding was determined to be of very low safety significance (Green).
Enforcement Technical Specification 3.3.7 requires, in part, that two containment hydrogen monitor channels be operable in Modes 1, 2 and 3. Technical Specification Action Statement 3.3.7.A requires, in part, that when one or more functions with one required containment hydrogen monitor channel is inoperable then the required channel be restored to an operable status within 30 days or a report to the NRC be initiated in accordance with Technical Specification 5.6.6. In addition, Technical Specification Action Statement 3.3.7.D requires, in part, that when two containment hydrogen monitor channels are inoperable that one channel is restored to operable status within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in hot standby within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in hot shutdown within the following 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.
Contrary to the above, from May 2001 through June 2001 and January 2002 through December 2002, while the plant was in Mode 1, the right channel containment hydrogen monitor was inoperable because the pipe caps for two test taps were not installed. In addition, in November 2002, while the plant was in Mode 1 with the right channel containment hydrogen monitor inoperable, the left channel containment hydrogen monitor was also inoperable for approximately 200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> because of scheduled maintenance.
This violation is associated with a self-revealed finding that is characterized by the significance determination process as having very low safety significance (Green) and is being treated as a Non-Cited Violation of Technical Specification 3.3.7, consistent with Section VI.A.1 of the NRC Enforcement Policy. (NCV 50-255/03-02-03)

.2 (Closed) LER 02-002, Automatic Reactor Trip and Safety System Actuation
a. Inspection Scope
The inspectors reviewed LER 02-002 to verify that the event was accurately described, determine if any violations of NRC requirements had occurred and to assess the appropriateness of identified corrective actions.
This issue was previously documented in Inspection Report 50-255/02-09 as a self-revealed Green finding and associated Non-Cited Violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, for the failure to rigorously evaluate industry operating experience information which resulted in inadequate preventive maintenance activities being developed for the 345 KV transmission lines that connect the plant and switchyard.
The inspectors did not identify any new information in the LER which was of concern and concluded that the completed and planned corrective actions were reasonable.
Therefore, this LER is closed.
b. Findings
No findings of significance were identified.
.3 (Closed) LER 03-001, Inoperable Steam Generator Low-Level Channels
a. Inspection Scope
The inspectors reviewed LER 03-001 to verify that the event was accurately described, determine if any violations of NRC requirements had occurred and to assess the appropriateness of identified corrective actions.
On January 15, 2003, at 8:15 p.m. licensee personnel identified that all four steam generator reactor protection system low-level trip setpoints on both steam generators were set below the allowable value specified in Technical Specification 3.3.1, Reactor Protective System Instrumentation. Consequently, all steam generator low-level trip instrument channels were declared inoperable and Technical Specification 3.0.3 was entered which required action be initiated within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> to shut down the plant to Mode 3, Hot Standby, within 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />.
Licensee personnel requested and received enforcement discretion from the NRC to extend the completion times in Technical Specification 3.0.3 by an additional 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> in order to conduct online repairs. Licensee personnel subsequently adjusted the trip setpoints to comply with Technical Specification requirements and the steam generator low-level reactor protection system trip functions were declared operable within the extended time allowed by the enforcement discretion. The enforcement discretion related to this event is discussed in Section 4OA5.3 of this report.
Licensee personnel evaluated this event and subsequently determined that the low-level trip setpoints had been set incorrectly since 1998. The event was caused by a vendor calculation error that was not previously identified and resulted in a biasing correction factor being applied to the level transmitters in the non-conservative direction.
This finding was more than minor because it affected the mitigating systems cornerstone objective by impacting the reactor protection systems capability to respond to a steam generator low-level initiating event to prevent undesirable consequences. However, while the steam generator low-level setpoints were below the allowable values specified in Technical Specifications, all the low-level setpoints were greater than the analytical values specified in the plant safety analysis. Therefore, plant safety would have been maintained during a steam generator low level initiating event.
The finding affected the mitigating systems cornerstone and was determined to be of very low safety significance (Green) using NRC Manual Chapter 0609, Appendix A, Significance Determination of Reactor Inspection Findings for At-Power Situations, because the finding:
C was not a design or qualification deficiency; C
did not represent the loss of the reactor protection systems safety function; and C
did not screen as potentially risk significant due to seismic, fire, flooding, or severe weather initiating event.
This licensee identified finding involved a violation of Technical Specification 3.3.1, Reactor Protective System Instrumentation, and the related enforcement aspects are discussed in Section 4OA7 of this report. This LER is closed.
b. Findings
No findings of significance were identified.
.4 Declared Unusual Event Due to Unexplained Service Water Bay Lowering Level
a. Inspection Scope
The inspectors reviewed the circumstances associated with the Unusual Event on February 16, 2003, which was declared due to the unexplained lowering level in the service water bay. The resident inspectors provided 24-hour site coverage after the Unusual Event was declared to monitor the licensees event response until the Unusual Event was terminated on February 19, 2003.
The inspectors reviewed the circumstances surrounding this event to assess whether any licensee performance issues existed which contributed to the initiation of the event.
Licensee operator response during the event was assessed under Personnel Performance Related to Non-Routine Plant Evolutions and Events, in Section 1R14.1 of this report.
b. Findings
Introduction No findings of significance or licensee performance deficiencies were identified during the inspectors review of the events which occurred. However, the inspectors did note that NUREG-0820, Integrated Plant Safety Assessment - Systematic Evaluation Program - Palisades Plant, refers to the ability of the plant to utilize a warm water recirculation pump as an alternate supply for the service water pumps if catastrophic damage were to occur to the intake pipe or other components that completely block intake flow. However, the warm water recirculation pump currently does not have the ability to perform this function; therefore, the inspectors opened an Unresolved Item to track whether or not the licensee is in nonconformance of commitments made in the Systematic Evaluation Program.
Description On February 16, 2003, at approximately 1:50 a.m. the Control Room received a service water bay low level alarm. The operators determined that there was reduced flow from the service water intake structure in Lake Michigan as opposed to an equipment problem in the plant. At 02:53 a.m. the Site Emergency Director declared an Unusual Event based on the Miscellaneous Emergency Action Level, due to the lowering service water bay levels. Operators responded by taking the manual actions specified in Alarm Response Procedure 7 and Off-Normal Procedure 6.1, Loss of Service Water.
Operator actions included securing the dilution water pumps, which were the largest service water load, lowering plant power level from 100 percent to approximately 90 percent and initiation of warm water recirculation to the service water bay from the make-up basin through the use of Pump P-5. Actions taken by the operators successfully stabilized level in the service water bay.
On February 16, 2003, divers performed inspections which identified that at least two sides of the intake crib appeared to be encased in frazil ice. Adverse weather conditions prevented the divers from inspecting all four sides of the intake crib. Licensee personnel also learned that municipal water plants on the eastern shore of Lake Michigan experienced the same phenomenon of frazil ice forming on the intake cribs. The Unusual Event was terminated on February 19, 2003, after inspections were completed of the intake crib and intake piping which revealed that no frazil ice remained and that the intake crib and piping was not damaged.
The inspectors reviewed industry operating experience and concluded that a performance issue did not exist with regard to this event. The licensees procedures contained the appropriate actions to abate the formation of frazil ice on the intake structure, mainly by reducing the largest service water loads and reducing plant power.
However, the inspectors did note that NRC NUREG-0820, Systematic Evaluation Program for the Palisades Nuclear Plant, contained commitments the licensee made to the NRC during the Integrated Assessment Program which were referenced in Updated Final Safety Analysis Report (UFSAR) Section 1.8.1, Systematic Evaluation Program, and Table 1.3.
Specifically, Section 4.7.1, Cooling Water System Structures Inspection, of NUREG-0820, referenced in UFSAR Table 1.3, states in part that the NRC staff determined that inspection of cooling water systems and structures as referenced in Regulatory Guide 1.127 did not have to be made, in part, because An alternate water supply for the service water pumps is available independent of the normal intake path.
This alternate supply is piped to the intake structure from the warm water recirculation pump (can be powered from emergency diesel generator) and takes a suction from the mixing basin or from the lake at the discharge structure.
However, the ability for the warm water recirculation pump to take a suction from the lake was not currently available due to the suction pipe being buried in sand. Also, the ability to take a suction from the mixing basin has not been available since the year 2000 due to the low levels in Lake Michigan.
The licensee initiated Condition Report CAP033802, Warm Water Recirculation Pump P-5, Potential Commitment Nonconformance, to evaluate this issue. The inspectors opened an Unresolved Item to track the licensees evaluation of this potential nonconformance of a commitment from the Systematic Evaluation Program.

.5 Declared Alert Due to a Fire With The Potential To Affect Safety-Related Equipment
a. Inspection Scope
The inspectors responded to the plant after an Alert was declared at 8:47 p.m. on March 18, 2003. The plant was in Mode 5, Cold Shutdown, when a fire alarm activated in the cable spreading room. Fire brigade personnel responded and reported a significant amount of smoke in the cable spreading room which prompted the Alert declaration due to a fire with the potential to affect safety-related equipment. The inspectors monitored licensee actions during the event and verified that the shutdown cooling system remained in service to remove reactor decay heat. The event was terminated at 11:26 p.m. on March 18, 2003, after the licensees preliminary investigation determined that the likely cause of the smoke was the circuit breaker for Charging Pump P-55A which was found damaged. This event was the subject of an NRC special inspection and the event details were documented in Inspection Report 50-255/03-05(DRP).
b. Findings
Findings associated with this event will be documented in NRC Special Inspection Report 50-255/03-05(DRP).
.6 Declared Alert Due to Loss of Offsite Power
a. Inspection Scope
On March 25, 2003, an Alert was declared at 11:21 a.m. after offsite power to the plant was lost unexpectedly which resulted in a loss of shutdown cooling to the reactor. The inspectors responded to the control room and observed the operators response to the event to ensure that appropriate plant procedures were utilized in an accurate and timely manner. The inspectors verified that Off-Normal Procedure 17, Loss of Shutdown Cooling, General Operating Procedure 14, Shutdown Cooling Operations, and Off-Normal Procedure 2.1, Loss of AC Power, were implemented as required to restore shutdown cooling and mitigate the event. The inspectors also verified that the Emergency Plan was implemented in an accurate and timely manner.
The inspectors walked down the control room panels to monitor key plant parameters including the primary coolant system temperature heatup rate. The inspectors also verified that the emergency diesel generators were operating properly in order to provide power to plant equipment necessary to re-establish shutdown cooling to the reactor.
The Alert emergency was downgraded to an Unusual Event after shutdown cooling was restored to the reactor with the shutdown cooling pump being powered from the emergency diesel generator. The inspectors provided 24-hour site coverage to monitor licensee actions until the Unusual Event was terminated on March 27, 2003, after offsite power to the plant was restored and the emergency diesel generators were secured.
This event was the subject of an NRC special inspection and the event details will be documented in Inspection Report 50-255/03-05(DRP).
b. Findings
Findings associated with this event will be documented in NRC Special Inspection Report 50-255/03-05(DRP).
4OA5 Other Activities
.1 (Closed) Unresolved Item (URI) 50-255/02-03-02:
Potential 125VDC Single-Failure Impact on Containment Spray In Inspection Report 50-255/02-03, Section 1R21.b.2, NRC inspectors documented a potential single-failure scenario whereby the containment spray system would be non-functional during a loss-of-coolant accident. At the end of the inspection, this issue was characterized as a finding that had a credible impact on safety, in that the plant may have been operated outside of the design basis. The issue was characterized as unresolved pending an Office of Nuclear Reactor Regulation (NRR) licensing basis determination.
To resolve this issue, discussions were held with NRR to review the Palisades licensing basis and determine whether the plant was licensed with breaker and fuse failures considered as passive. Participants in those discussions were staff from NRR projects and the electrical branch, and Region III staff. As a result of the discussions, NRR confirmed that breakers and fuses which did not have to change state to accomplish the intended safety function, as those involved in the scenario, were considered passive devices.
As discussed in the inspection report, NRR was requested to determine whether a backfit, in accordance with 10 CFR 50.109, to conform with present regulatory and industry guidance was appropriate. It was determined, that because of the extremely low probability of a large break loss-of-coolant accident coincident with the occurrence of the proposed single failure, a backfit could not be justified. This URI is closed.
.2 (Closed) Violation (VIO) 50-255/01-08-01, Smoke Detectors Inadequate - Northwest
Portion of Cable Spreading Room During a triennial fire protection inspection completed in September 2001, the NRC identified a finding of to be determined significance and associated Apparent Violation (AV) 50-255/01-08-01 regarding inadequate smoke detectors in the northwest portion of the cable spreading room.
The NRC subsequently characterized the finding as White (i.e. an issue with low to moderate safety significance, which may require additional NRC inspections) in a letter dated October 26, 2001, from the NRC to Mr. Douglas E. Cooper, Site Vice President, Palisades Nuclear Plant, Nuclear Management Company, LLC. A Notice of Violation was also issued with the White finding. Nuclear Management Company did not contest the violation or the characterization (White) of the risk significance for the finding.
On July 25, 2002, the NRC completed a supplemental inspection in accordance with Inspection Procedure 95001 which assessed the adequacy of the corrective actions for the White finding and associated violation. The inspection was documented in Inspection Report 50-255/02-08(DRS).
During the supplemental inspection, the inspectors concluded that the licensee had developed a comprehensive corrective action plan to address the issue as well as any other historical NFPA (National Fire Protection Association) code conformance issues.
The inspectors also concluded that adequate measures were in place to prevent a similar occurrence from recurring. Therefore, this violation is closed.
.3 (Closed) Unresolved Item 50-255/03-02-05:
Review of Notice of Enforcement Discretion (NOED) 03-3-001 For Nuclear Management Company LLC Regarding Palisades The inspectors reviewed the circumstances associated with issuing NOED 03-3-001 and the basis for the NOED request to determine if a failure to comply with regulatory requirements contributed to the need for enforcement discretion. The inspectors also verified that licensee personnel complied with the compensatory actions noted in the NOED.
On January 15, 2003, at 8:15 p.m. licensee personnel identified that all four steam generator reactor protection system low-level trip setpoints on both steam generators were set below the allowable value specified in Technical Specification 3.3.1, Reactor Protective System Instrumentation. Consequently, all steam generator low-level trip instrument channels were declared inoperable and Technical Specification 3.0.3 was entered which required that action be initiated within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> to shut down the plant and that the plant be in Mode 3, Hot Standby, within 7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />. Licensee personnel requested enforcement discretion to extend the completion times in Technical Specification 3.0.3 by an additional 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br /> to avoid a plant shutdown and conduct repairs online.
The NRC verbally granted NOED 03-3-001 at 12:07 a.m. on January 16, 2003.
Licensee personnel subsequently adjusted the trip setpoints to comply with Technical Specification requirements and the steam generator low-level reactor protection system trip functions were declared operable at 8:00 p.m. on January 16, 2003.
No findings of significance were identified during the inspectors review of the basis of the NOED request and the licensee's implementation of compensatory actions required by the NOED. Therefore, this URI is closed.
This issue was determined to be a licensee identified finding which involved a violation of Technical Specification 3.3.1, Reactor Protective System Instrumentation. The event is discussed further in Section 4OA3.3 of this report and the related enforcement aspects for the violation are discussed in Section 4OA7 of this report.
4OA6 Meetings
.1 Exit Meeting
The inspectors presented the inspection results to Mr. D. Cooper and other members of licensee management on April 11, 2003. Licensee personnel acknowledged the findings presented. The inspectors asked licensee personnel whether any materials examined during the inspection should be considered proprietary. No proprietary information was identified.
.2 Interim Exit Meeting
Interim Exit was conducted for:
- Physical Protection Inspection with Mr. B. Rowland on January 31, 2003.
- Radiation Protection Inspection with Mr. D. Cooper on April 2, 2003.
4OA7 Licensee Identified Violations
The following finding of very low safety significance (Green) was identified by the licensee and was a violation of NRC requirements which met the criteria of Section VI of the NRC Enforcement Policy, NUREG-1600, for being dispositioned as a Non-Cited Violation.
C Technical Specification 3.3.1, Reactor Protective System Instrumentation, required, in part, that four reactor protective system trip units including the associated steam generator low-level instrument channels be operable in Mode 1. Contrary to this, on January 15, 2003, with the plant in Mode 1, all steam generator low-level instrument channels on both steam generators were determined to be inoperable. This event was documented in the licensees corrective action program as CAP032931, Level Transmitter Static Pressure Effect Not Incorporated Correctly. This finding was of very low safety significance because the finding did not represent the loss of the reactor protection systems safety function.
