UNITED STATES NUCLEAR REGULATORY COMMISSION May 7, 2009

SUBJECT:

JAMES A. FITZPATRICK NUCLEAR POWER PLANT - NRC INTEGRATED INSPECTION REPORT 05000333/2009002

Dear Mr. Dietrich:

On March 31, 2009, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your James A. FitzPatrick Nuclear Power Plant (FitzPatrick). The enclosed inspection report documents the inspection results which were discussed on April 9, 2009, with you and other members of your staff.

The inspection examined activities conducted under your license as they relate to safety and compliance with the Commissions rules and regulations and with the conditions of your license.

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

Based on the results of this inspection, two NRC identified findings of very low safety significance (Green) were identified. These findings were determined to be violations of NRC requirements. However, because of the very low safety significance, and because the violations were entered into your corrective action program, the NRC is treating these violations as non-cited violations (NCVs) in accordance with Section VI.A.1 of the NRC Enforcement Policy. If you contest any NCV, you should provide a response within 30 days of the date of the inspection report, with the basis for your denial, to the U. S. Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington, D.C. 20555-0001; with a copy to the Regional Administrator, Region I; Office of Enforcement; U. S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Senior Resident Inspector at FitzPatrick. In addition, if you disagree with the characterization of any finding in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your disagreement, to the Regional Administrator, Region I, and the NRC Resident Inspectors at FitzPatrick. The information you provide will be considered in accordance with Inspection Manual Chapter 0305. In accordance with 10 CFR Part 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be made available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of the NRCs document system (ADAMS), accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Sincerely,

/RA/

SUMMARY OF FINDINGS

IR 05000333/2009002; 01/01/2009 - 03/31/2009; James A. FitzPatrick Nuclear Power Plant;

Surveillance Testing and Event Follow-Up.

The report covered a three-month period of inspection by resident inspectors and announced inspections by region based inspectors. One Severity Level IV and one Green finding associated with two non-cited violations were identified. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609,

Significance Determination Process (SDP). The cross-cutting aspect for each finding was determined using IMC 0305, Operating Reactor Assessment Program. Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 4, dated December 2006.

NRC-Identified and Self-Revealing Findings

Cornerstone: Mitigating Systems

  • Severity Level IV: The inspectors identified a Severity Level IV, non-cited violation (NCV) because Entergy did not provide a written 60-day report to the NRC as required by 10 CFR 50.73 relative to a condition which was prohibited by Technical Specifications (TS) 3.8.3. Specifically, on several occasions between September 2006 and July 2007 the volume for either the A or B fuel oil storage tanks (FOST) was such that there was an insufficient quantity of fuel oil to provide a seven day fuel oil supply for the associated emergency diesel generator (EDG) as required per Technical Specifications. Entergy personnel, in determining past reportability, improperly credited the associated fuel oil day tank towards the seven day supply and erroneously concluded on September 18, 2007, that the issue was not reportable. Entergys corrective actions included initiation of CR-JAF-2008-04323 and issuance of licensee event report (LER) 2009-001, Inadequate Engineering Calculation Results in Insufficient Inventory in EDG Fuel Oil Storage Tanks. In addition, Entergy revised applicable procedures to ensure the fuel oil storage tanks contain adequate fuel oil inventory to remain in compliance with the TS.

This violation involved a failure to make a required report to the NRC and is considered to impact the regulatory process. Such violations are dispositioned using the traditional enforcement process instead of the Significance Determination Process.

Using the Enforcement Policy Supplement I, Reactor Operations, example D4 which states, A failure to make a required LER; the NRC determined this violation is more than minor and categorized as a Severity Level IV violation.

The inspectors determined that this finding had a cross-cutting aspect in the area of problem identification and resolution related to the evaluation component because Entergy personnel did not properly consider the TS basis and, therefore, did not properly evaluate the reportability for the EDG FOSTs. (P.1(c)) (Section 4OA3)

Cornerstone: Barrier Integrity

  • Green: The inspectors identified an NCV of very low safety significance of 10 CFR 50,

Criterion XVI, Corrective Action, because Entergy did not identify and correct a condition adverse to quality related to a control room envelope boundary door.

Specifically, on several occasions, Entergy did not identify and implement adequate actions to ensure a control room envelope boundary door, 70DOR-A-300-5, remained latched and able to perform its safety function. Entergy implemented corrective actions which included repair of the latching mechanism to improve the reliability of the door and initiated condition reports CR-JAF-2009-01021 and CR-JAF-2009-01070.

This finding was greater than minor because it affected the barrier integrity attribute of structures, systems, components, and barrier performance under maintaining radiological barrier functionality of the control room and affected the cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding, reactor coolant system, and containment) protect operators in the control room from radionuclide releases caused by accidents or events. The finding was evaluated using the SDP Phase I and Phase III because the finding represented a degradation of the barrier function provided for the control room against toxic atmosphere and smoke as well as radiological conditions. The finding was determined to be of very low safety significance, because the amount of time the door was unlatched and ajar was limited to 51 days and, considering the TS allowed outage time of 90 days, the maximum potential time of 51 days represented very low safety significance considering the low probability of a design basis accident during this time period.

The inspectors determined this finding had a cross-cutting aspect in the area of problem identification and resolution related to the identification component because Entergy personnel did not identify the degraded condition completely and did not recognize the impact that the degraded CRE boundary door had on the control room envelope. (P.1(a)) (Section 1R22)

Licensee-Identified Violations

None

REPORT DETAILS

Summary of Plant Status

The James A. FitzPatrick Nuclear Power Plant (FitzPatrick) began the inspection period operating at 100 percent reactor power. On January 14, 2009, Entergy reduced reactor power to 55 percent to perform a control rod sequence exchange and to repair leaking condenser tubes and returned to 100 percent the following day. On February 18, 2009, the A traveling water screen was isolated to facilitate repairs. This resulted in an increase in water velocity through the operating traveling water screens and subsequent transport of additional debris to the condensers. The following condenser cleaning operations were conducted to address increased condenser differential temperature as a result of the additional debris while the A traveling water screen was isolated:

  • On February 19, 2009, Entergy reduced reactor power to 75 percent to clean the B2 condenser water box and returned to 100 percent reactor power the same day;
  • On February 21, 2009, Entergy reduced reactor power to 75 percent to clean the B1 and B2 condenser water boxes and returned to 100 percent reactor power the following day;
  • On February 24, 2009, Entergy reduced reactor power to 75 percent to clean the B1 and B2 condenser water boxes and returned to 100 percent the same day; and
  • On February 26, 2009, Entergy reduced reactor power to 85 percent to clean the A1, B1 and B2 condenser water boxes and returned to 100 percent the following day.

Operators maintained the reactor at 100 percent power for the remainder of the inspection period.

These activities represented six surveillance testing inspection samples.

b. Findings

Introduction:

The inspectors identified an NCV of very low safety significance of 10 CFR 50, Criterion XVI, Corrective Action, because Entergy did not identify and correct a condition adverse to quality related to a control room envelope (CRE) boundary door.

Specifically, Entergy did not identify and implement adequate actions to ensure the safety-related CRE boundary door, 70DOR-A-300-5, remained latched and able to perform its safety function.

Description:

Following the performance of ST-18BB, CREVAS B Operability Test, on March 19, 2009, the inspectors walked down areas involved during the surveillance test approximately four hours after completion to ensure all equipment had been restored to an operable condition. The inspectors identified door 70DOR-A-300-5, a CRE boundary door between the control room chiller room and the control room HVAC room, to be unlatched and slightly ajar.

After discovering the door unlatched and ajar, the inspectors verified no Entergy personnel were in the two rooms associated with door 70DOR-A-300-5, closed and latched the door, and notified the control room personnel of the deficiency. Entergy personnel verified the doors condition, initiated condition report CR-JAF-2009-001021, and initiated an engineering request to consider installing alarm capability to monitor the condition of the door. In addition, Entergy had previously identified the door to be unlatched on January 31, 2009 and initiated CR-JAF-2009-00387. Entergy closed CR-JAF-2009-00387 on February 6, 2009, considering its purpose to be sufficient for trending purposes only. The inspectors concluded it would have been reasonable to investigate the latch mechanism condition at that time.

On March 23, 2009, the inspectors identified door 70DOR-A-300-5 unlatched a third time and the door handle latch mechanism to be loose. Entergy continued to emphasize to personnel the importance of ensuring the door latched and attempted to tighten the mechanism.

On March 24, 2009, the inspectors identified door 70DOR-A-300-5 unlatched a fourth time and also identified that the latch mechanism was still loose. In addition, the inspectors identified that the latch became unlatched when the door was flexed a small amount. This flexing would occur with changes in the differential pressure across the door, which is a common event. Entergy initiated CR-JAF-2009-01070 and performed repairs and enhancements to the latching mechanism to improve the reliability of the door.

In order for the CREVAS subsystems to be considered operable, the CRE boundary must be maintained such that the CRE occupant dose from a large radioactive release does not exceed the calculated dose in the licensing basis consequence analyses for design basis accidents, and that CRE occupants are protected from hazardous chemicals and smoke.

Door 70DOR-A-300-5 must be closed and latched in order to maintain these conditions.

Although procedure AP-19.18, Control Room Envelope Habitability Program, revision 0, allows intermittent opening of the CRE boundary under administrative controls, as permitted by a note included in TS 3.7.3, the doors condition in this case was not controlled and its state was unknown and unreliable.

Entergys corrective actions included repair and enhancements to the latching mechanism to improve the reliability of the door, initiating condition reports CR-JAF-2009-01021 and CR-JAF-2009-01070, and initiating an engineering request to consider installing alarm capability when the door is not maintained closed and latched.

Analysis:

There was an NRC-identified performance deficiency in that Entergy did not promptly identify and correct a condition adverse to quality associated with the CRE boundary door. This finding is greater than minor because it affected the barrier integrity attribute of structures, systems, components, and barrier performance under maintaining radiological barrier functionality of the control room and affected the cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding, reactor coolant system, and containment) protect the public from radionuclide releases caused by accidents or events.

The finding was evaluated using IMC 0309, Significance determination process, (SDP)

Phase I and screened to a SDP Phase III review because the finding represented a degradation of the barrier function provided for the control room against toxic atmosphere and smoke as well as radiological conditions. The finding was determined to be of very low safety significance (Green) because the amount of time the door was unlatched and ajar was limited to 51 days. The mitigating actions immediately required by action statement B.1 are required by B.2 to be verified within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to ensure CRE occupant exposures to radiological, chemical, and smoke hazards will not exceed limits. In addition, action B.3 to restore the CRE boundary to operable status has a required completion time of 90 days. Therefore, considering the allowed outage time of 90 days, the maximum potential time of 51 days represents very low safety significance considering the low probability of a design basis accident during this time period.

The inspectors determined that this finding had a cross-cutting aspect in the area of problem identification and resolution within the identification component because Entergy personnel did not identify the degraded condition completely and therefore did not recognize the impact that the degraded CRE boundary door had on the control room envelope. (P.1(a))

Enforcement:

10 CFR 50, Appendix B, Criterion XVI, Corrective Action, requires, in part, that measures be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and non-conformances are promptly identified and corrected. Contrary to the above, between January 31 and March 24, 2009, Entergy did not implement measures to promptly identify and correct a condition adverse to quality associated with a CRE boundary doors reliability. This resulted in short periods of time where the CRE boundary door was inoperable. Entergy took corrective actions to repair the latching mechanism to improve the reliability of the door. Because this violation was of very low safety significance, was not repetitive or willful, and it was entered into Entergys corrective action program, this violation is being treated as an NCV, consistent with section VI.A.1 of the NRC Enforcement Policy. (NCV 05000333/2009002-01: Inoperable Control Room Envelope Door.)

Calibrators 2 Shepherd 89 survey instrument calibrators (RP Instrument Calibration Lab)1 Shepherd 142-10 panoramic calibrator (Radwaste Building, 298 elevation)4. The inspectors reviewed radiological incidents involving internal exposures identified by condition reports for 2008. In addition, dosimetry electronic records were queried for any internal exposures >50 mrem committed effective dose equivalent. None were identified for further review.

5. Condition reports were reviewed (See Section 4OA2), with respect to radiation protection program deficiencies to determine if the deficiencies were appropriately characterized and corrected commensurate with their safety significance.

6. Based on the condition reports reviewed (See Section 4OA2), no repetitive deficiencies were identified for further follow up.

7. With respect to the RP portable instruments listed in 3) above, the instruments calibration expiration and response checks were reviewed. The applicable response check beta-source and instrument sign-out procedures were also reviewed. The inspectors queried radiation protection technicians regarding appropriate instrument selection and observed self verification of instrument operability prior to use.

8. Emergency plan-specified self contained breathing apparatus (SCBA) equipment and qualified users were sampled based on Fitzpatrick Emergency Plan documents, this included inspection of selected SCBAs (Control Room, Operations Support Center, Security), air bottle cascade systems, the Bauer Breathing Air Compressor (39AC-8),and the Service Air Compressors (39AC-2A/2B/2C). SCBA qualification records for all on-shift reactor operators were verified for currency and that required spectacles were stored nearby and readily available. The inspectors also verified that air used to fill the SCBAs met the Grade D quality criteria of the Compressed Gas Association.

9. The inspectors examined selected SCBA units in the main control room, security building and operations support center for periodic air cylinder hydrostatic testing and maintenance records. Review of approved replacement parts documentation and certification of the repair personnel was performed.

OTHER ACTIVITIES (OA)

4OA2 Identification and Resolution of Problems

Main article: IP 71152

.1 Review of Items Entered into the Corrective Action Program

a. Inspection Scope

As required by Inspection Procedure 71152, Identification and Resolution of Problems, to identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed a daily screening of all items entered into Entergys corrective action program. The review was accomplished by accessing Entergys computerized database for CRs and attending CR screening meetings.

In accordance with the baseline inspection procedures, the inspectors selected items across the initiating events, mitigating systems, and barrier integrity cornerstones for additional follow-up and review. The inspectors assessed Entergys threshold for problem identification, the adequacy of the cause analyses, and extent of condition review, operability determinations, and the timeliness of the specified corrective actions. The CRs reviewed are listed in the Attachment.

b. Assessment and Observations No findings of significance were identified. The inspectors determined that Entergy staff appropriately identified equipment, human performance and program issues at an appropriate threshold and entered them into the corrective action program.

.2 Annual Sample: Operator Workaround Program

Main article: IP 71152

a. Inspection Scope

The inspectors reviewed the cumulative effects of operator workaround conditions on the reliability, availability, potential for mis-operation of a system, and on the operators ability to implement abnormal or emergency operating procedures. The inspectors reviewed the results of Entergy surveillance test ST-99H, Operations Cumulative Impact Assessment, and the resolution of items identified in the assessment. The inspectors reviewed Entergys program for identifying operator workaround conditions at an appropriate threshold and for entering them into the corrective action program. In addition, the inspectors reviewed operating department records including standing orders for operational decision-making issues and operability evaluations.

This activity constitutes one inspection sample.

b. Assessment and Observations No findings of significance were identified. The inspectors determined that Entergys corrective action program was effectively used to identify and resolve operator workaround conditions.

4OA3 Event Follow-up

Main article: IP 71153

.1 (Closed) Licensee Event Report (LER) 05000333/2009001-00, Inadequate Engineering

Calculation Results in Insufficient Inventory in EDG Fuel Oil Storage Tanks

Introduction:

The inspectors identified a Severity Level IV, non-cited violation (NCV)because Entergy did not provide a written 60-day report to the NRC as required by 10 CFR 50.73 relative to a condition which was prohibited by Technical Specifications (TS)3.8.3. Specifically, on several occasions between September 2006 and July 2007 the volume for the A or B fuel oil storage tanks (FOST) was such that there was an insufficient quantity of fuel oil to provide a seven day fuel oil supply for the associated emergency diesel generator as required per TS.

Description:

On June 29, 2007, Entergy personnel determined that the TS allowed a range of energy (or heat) content of the fuel oil as represented by American Petroleum Institute (API) gravity from 27 degrees to 39 degrees, which would result in the TSs specified minimum volume of 32,000 gallons to be insufficient for seven days continuous operation of the emergency diesel generators without resupply from an external source.

Entergy initiated CR-JAF-2007-02392 in order to evaluate and correct the condition and evaluate the issue for reportability based upon actual past FOST volumes and API gravities.

In addition, as documented in NRC inspection report 05000333/2007006, the NRC determined that Entergy staff did not properly identify and evaluate the potential for vortexing in the EDG fuel oil transfer pump suction inlet piping. Specifically, Entergys EDG FOST inventory calculation did not include any allowance for suction line submergence to prevent air entrainment resulting from the effects of vortexing. Entergy personnel initiated CR-JAF-2007-02490 in order to evaluate and correct the condition and evaluate the issue for reportability in combination with CR-JAF-2007-02392 due to the cumulative effect of the two issues.

Although Entergy maintains the quantity of oil in the FOSTs at greater than the minimum required by TS for both volume and heat content, the inspectors determined that there were, at a minimum, four occasions between September 17, 2006 and July 6, 2007 in which a condition prohibited by TSs occurred, i.e. the FOST did not have a sufficient quantity of fuel oil to support seven days of operation for a duration greater than 16 days (the duration allowed by TSs prior to requiring actions to begin shutdown of the plant).

Specifically, the A FOST did not have a sufficient capacity at least three times for durations of 19, 51, and 21 days, and the B FOST did not have a sufficient quantity at least once for 19 days.

The inspectors determined that Entergy staff improperly credited the fuel oil stored within the day tank (crediting a volume of fuel oil up to 525 gallons) in order to conclude that there had not been a time when seven days of fuel oil supply had been not been maintained for greater than 16 days, including those four occasions. The inspectors determined that crediting the day tank supply, however, conflicts with the safety function of the FOST, as described in the stations licensing basis, to be the sole source of the seven days of supply. Specifically, at the end of seven days of EDG operation, only the FOST may be analyzed to be depleted, and not the day tank.

The safety function for the emergency AC power system with respect to the fuel oil supply is defined within the Final Safety Analysis Report, as updated in 2007, in Section 8.6, Emergency AC Power System and specifically within Subsection 8.6.7, Safety Evaluation, by stating The two diesel units comprising each emergency AC power source are capable of starting and operating continuously under postulated accident conditions for a period of seven days, using fuel stored in underground fuel storage tanks. This safety function design is consistent with Regulatory Guide 1.137, Fuel-Oil Systems for Standby Diesel Generators, Revision 1 and ANS 59.51/ANSI N195-1976, American National Standard for Fuel Oil Systems for Standby Diesel-Generators and the most recent revision ANSI/ANS-59.51-1997.

This condition met the criteria for reporting under 10 CFR 50.73 (a)(2)(i)(B) in that the condition was not allowed by the plants TSs (i.e. that after the sixteen days of allowed outage time the plant was required to begin shutting down, but did not). However, on September 18, 2007, Entergy incorrectly concluded that no reportability criteria applied and decided to not submit a 60-day report.

Analysis:

The NRC identified a performance deficiency in that Entergy did not provide a 60-day written report, as required by 10 CFR 50.73(a)(2)(i)(B). This violation involved a failure to make a required report to the NRC and is considered to impact the regulatory process. Such violations are dispositioned using the traditional enforcement process instead of the Significance Determination Process. Using the Enforcement Policy Supplement I, Reactor Operations, example D4 which states, A failure to make a required LER; the NRC determined this violation impacted the regulatory process and is more than minor and categorized as a Severity Level IV violation.

Entergys corrective actions included initiating CR-JAF-2008-04323 and filing LER 2009-001, Inadequate Engineering Calculation Results in Insufficient Inventory in EDG Fuel Oil Storage Tanks on January 12, 2009. In addition, as part of the corrective actions already performed as part of CR-JAF-2007-02392 and CR-JAF-2007-02490, Entergy had revised the applicable procedures to ensure the FOSTs contain adequate fuel oil inventory to remain in compliance with the Technical Specifications and pursued license revisions to the Technical Specifications to remove non-conservative values.

The inspectors determined this finding had a cross-cutting aspect in the area of problem identification and resolution within the corrective action program component because Entergy personnel incorrectly concluded that the safety function to provide a seven day supply of fuel oil could utilize sources other than the FOST, specifically the day tank, and therefore did not properly evaluate for reportability a condition adverse to quality on September 18, 2007. (P.1(c))

Enforcement:

10 CFR 50.73 requires licensees to submit a LER for any operation or condition which was prohibited by the plants Technical Specifications within 60 days of discovering the event. Contrary to the above, Entergy failed to submit a report within 60 days of June 29, 2007, when the event associated with inadequate EDG fuel oil supply was discovered. Because this violation was of very low safety significance, was not repetitive or willful, and it was entered into Entergys corrective action program, this violation is being treated as an NCV, consistent with section VI.A.1 of the NRC Enforcement Policy. (NCV 05000333/2009002-02: Failed to Submit an LER For a Condition Prohibited by TS Associated With EDG Fuel Oil Supply.)

4OA5 Other Activities

.1 (Closed) Unresolved Item (URI) 05000333/2008003-01: Station Batteries With Indications

On the Negative Plate Straps As documented in inspection report 05000333/2008003, the inspectors identified indications on the negative plate straps of multiple cells of station battery 71SB-1 and one cell of station battery 71SB-2 that visually appeared to be cracks. Entergy removed cell 23 from service during their Fall 2008 refueling outage. Cell 23 was disassembled and the negative plate strap was inspected in order to characterize the indication.

Without electrolyte and container material to obscure the view, Entergy personnel determined that the suspected cracks were marks that appear on the surface against the tooling and away from the welding torch and its operator. The tooling acts as a dam that prevents molten lead from flowing into unintended areas. Lead in contact with the tooling can develop thermal gradients causing it to freeze in shapes resembling plains, creases, striations, and laminations. In this case, the lead had frozen into shapes that resembled cracks.

The inspectors reviewed Entergys analysis, including photographs of the negative plate strap with the electrolyte and container material removed, and concluded that the suspected cracks were surface anomalies. Therefore, no adverse condition existed and no violation of regulatory requirements was identified by the inspectors. URI 05000333/2008003-01, Station Batteries with Indications on the Negative Plate Straps, is closed.
