FINDINGS

IR 05000333/2007-004; 07/01/2007 - 09/30/2007; James A. FitzPatrick Nuclear Power Plant; Maintenance Effectiveness. The report covered a three-month period of inspection by resident inspectors. One Green

finding was 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). Findings for which the

SDP does not apply may be Green or be assigned a severity level after
NRC management review. The
NRC 's program for overseeing the safe operation of commercial nuclear power reactors is described in

NUREG-1649, "Reactor

Oversight Process," Revision 4, dated December 2006.

A. [[]]

NRC-Identified and Self-Revealing Findings Cornerstone: Mitigating Systems * Green. A self-revealing finding was identified involving inadequate corrective actions when Entergy did not correct an adverse condition on the reactor core isolation cooling (RCIC) system flow instrument sensing lines. The condition allowed air

bubbles to form in the sensing lines, resulting in an erroneous flow indication. Consequently, the

RCIC system would not have been able to achieve its design flow rate of 410 gallons per minute (gpm). Entergy entered the condition into their corrective action program and implemented interim corrective actions by revising the

RCIC operating procedure to vent the sensing lines. In addition, Entergy has

scheduled activities to correct the instrument sensing line condition. The inspectors determined that this finding is more than minor because it is associated with the equipment performance attribute of the Mitigating Systems cornerstone; and, it impacted the cornerstone objective of ensuring the availability,

reliability, and capability of the

RCIC system to respond to initiating events to prevent undesirable consequences. Specifically, the
RCIC system would not have been able to achieve its design flow rate of 410 gpm. The inspectors evaluated this finding using Phase 1 of
IMC 0609, Appendix A,
AS [[ignificance Determination of Reactor Inspection Findings for At-Power Situations,@ and determined it to be of very low safety significance (Green) because it was not associated with a design or qualification deficiency, it did not represent any actual loss of a system safety function, it did not represent the actual loss of a safety function of a single train for greater than its Technical Specification allowed outage time, and it was not potentially risk significant due to a seismic, flooding, or severe weather initiating event. (Section 1R12) B. Licensee-Identified Violations None.]]
REPORT [[]]

DETAILS Summary of Plant Status The James A. FitzPatrick Nuclear Power Plant began the inspection period operating at full power. On August 20, 2007, Entergy shut down the plant to repair a leaking safety relief valve.

Following repairs, the plant was returned to full power on August 24, 2007. On September 12, 2007, operators initiated a manual reactor scram due to lowering plant cooling water intake level which was caused by lake algae intrusion. Following repairs to the traveling water screens and execution of a monitoring plan to assure availability of cooling water systems, the plant was started up on September 14, 2007, and returned to full power on September 16, 2007. The

plant continued to operate at or near full power for the remainder of the inspection period. 1.

REACTO R

SAFETY Cornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity 1R01 Adverse Weather Protection (71111.01 - 1 sample) a. Inspection Scope The inspectors completed one adverse weather protection sample. High ambient

temperature and increased lake temperature were observed during early July 2007. To assess licensee actions and equipment performance, the inspectors reviewed Entergy's

actions and toured risk significant areas including the emergency diesel generator (EDG) building and east and west cable tunnels. The inspectors used Administrative Procedure 12.04, "Seasonal Weather Preparations," as a guide. The documents reviewed are listed in the Attachment. b. Findings No findings of significance were identified. 1R04 Equipment Alignment .1 Partial System Walkdown (71111.04Q - 4 samples) a. Inspection Scope The inspectors performed four partial system walkdowns to verify the operability of

redundant or diverse trains and components during periods of system train unavailability or following periods of maintenance. The inspectors referenced the system procedures, the Updated Final Safety Analysis Report (UFSAR), and system drawings in order to verify that the alignment of the available train was proper to support its required safety

2functions. The inspectors also reviewed applicable condition reports (CRs) and work orders to ensure that Entergy had identified and properly addressed equipment discrepancies that could potentially impair the capability of the available equipment train, as required by

10 CFR Part 50, Appendix B, Criterion

XVI, "Corrective Action." The documents reviewed are listed in the Attachment. The inspectors performed a partial walkdown of the following systems which represented four inspection samples:

modifications, operator workarounds, and items tracked by plant engineering were also reviewed to assess their collective impact on system operation. In addition, the inspectors reviewed the CR database to verify that the equipment problems were being identified and appropriately resolved. The documents reviewed are listed in the Attachment. The inspection represented one inspection sample. b. Findings No findings of significance were identified.

31R05 Fire Protection (71111.05Q - 9 samples) a. Inspection Scope The inspectors conducted a tour of several fire areas to assess the material condition and operational status of fire protection features. The inspectors verified, consistent with applicable administrative procedures, that: combustibles and ignition sources were adequately controlled; passive fire barriers, manual fire-fighting equipment, and

suppression and detection equipment were appropriately maintained; and compensatory measures for out-of-service, degraded, or inoperable fire protection equipment were implemented in accordance with Entergy's fire protection program. The inspectors evaluated the fire protection program against the requirements of Licensee Condition 2.C.3. The documents reviewed are listed in the Attachment. This inspection

represented nine inspection samples for fire protection tours and was conducted in the following plant areas: * Fire Area/Zone

Findings No findings of significance were identified. 1R06 Flood Protection Measures .1 Internal Flooding (71111.06 - 1 sample) a. Inspection Scope The inspectors reviewed selected risk-important plant design features and Entergy's procedures intended to protect the plant and its safety-related equipment from internal flooding events. The inspectors reviewed flood analysis and design documents, including the Individual Plant Examination and the]]
UFS [[]]

AR, engineering calculations, and abnormal operating procedures. The documents reviewed are listed in the Attachment.

Inspections in the following plant areas represented one sample: * Relay room; * North cable tunnel; and * South cable tunnel.

b. Findings No findings of significance were identified. 1R11 Licensed Operator Requalification Program .1 Resident Inspector Quarterly Review (71111.11Q - 1 sample) a. Inspection Scope On August 13, 2007, the inspectors observed licensed operator simulator training to assess operator performance during several scenarios to verify that operator performance was adequate and evaluators were identifying and documenting crew

performance problems. The inspectors evaluated the performance of risk significant operator actions, including the use of emergency operating procedures. The inspectors assessed the clarity and effectiveness of communications, the implementation of appropriate actions in response to alarms, the performance of timely control board operation and manipulation, and the oversight and direction provided by the shift

manager. The inspectors also reviewed simulator fidelity to evaluate the degree of similarity to the actual control room. Licensed operator training was evaluated against the requirements of

10 CFR [[Part 55, "Operators' Licenses." The documents reviewed are listed in the Attachment. This observation of operator simulator training represented one inspection sample. b. Findings No findings of significance were identified. 1R12 Maintenance Effectiveness (71111.12Q - 3 samples) a. Inspection Scope The inspectors reviewed performance-based problems involving selected in-scope structures, systems, or components (]]
SSC s) to assess the effectiveness of the maintenance program. The reviews focused on: * Proper Maintenance Rule scoping in accordance with
10 CFR Part 50.65; * Characterization of reliability issues; * Changing system and component unavailability; * 10
CFR Part 50.65 (a)(1) and (a)(2) classifications; * Identifying and addressing common cause failures; * Trending of system flow and temperature values; * Appropriateness of performance criteria for
SSC s classified (a)(2); and * Adequacy of goals and corrective actions for

SSCs classified (a)(1).

5The inspectors reviewed system health reports, maintenance backlogs, and Maintenance Rule basis documents. The inspectors evaluated the maintenance program against the requirements of 10 CFR Part 50.65. The documents reviewed are listed in the Attachment. The following Maintenance Rule samples were reviewed and represent three inspection samples: * Reactor Core Isolation Cooling system; * Standby gas treatment system; and * Automatic depressurization system. b. Findings .1 Introduction: A Green self-revealing finding was identified involving inadequate corrective actions when Entergy did not correct an adverse condition on the reactor core

isolation cooling (RCIC) system flow instrument sensing lines. The condition allowed air bubbles to form in the sensing lines, resulting in an erroneous flow indication. Consequently, the

RCIC system would not have been able to achieve its design flow rate of 410 gallons per minute (gpm). Description: On May 4, 2006, control room operators observed a reading of approximately 50 gpm on
RCIC pump discharge flow Indicator
13FI -91 and declared
RCIC inoperable. The
RCIC pump was not being run at the time. Entergy found that air saturation of the water in the

RCIC flow instrumentation sensing lines, in conjunction with inadequate sloping of the instrument lines, led to the entrapment of air bubbles in

the sensing lines and the resultant erroneous flow indication. Entergy determined that

RCIC would not have been able to achieve its design flow rate of 410 gpm. The
RCIC injection flow rate is determined by an automatic flow controller, which adjusts the speed demand setting of the
RC [[]]

IC turbine controls. The turbine speed is

determined by a comparison between the indicated flow as read on the

RCIC Pump Discharge Flow Indicator 13
FI -91 and the controller setpoint. Air entrapment in the negatively sloped
RCIC instrument lines resulted in indicated flow being higher than actual flow. The
RCIC [[flow controller adjusts the turbine speed demand to maintain indicated flow rate at the setpoint. Because indicated flow was higher than actual flow as a result of this condition, the actual injection flow rate would be less than desired. Entergy had previously identified problems with instrument line slope. On January 24, 2001, high pressure coolant injection (HPCI) system flow indicated 1400 gpm with the system in the standby condition.]]
HPCI was declared inoperable and a root cause analysis was performed in which Entergy determined that the
HPCI erroneous flow indication was caused by the negative sloping of the instrument sensing lines, air entrapment in the sensing lines and inadequate instrument venting. As part of the extent of condition review, the
RCIC system was inspected and Entergy concluded that the sloping of the
RCIC instrument lines could result in air entrapment and erroneous flow indications. Work Order (WO)
JF -010077107 and
JF -010077114 addressed and corrected the sloping of the instrument sensing lines for the
HP [[]]

CI flow instrumentation in February,

2001. However, Equivalent Change

JE -01-141 issued on September 24, 2001 did not correct the
RCIC instrument line slope to a minimum of one quarter inch per foot of sensing line run or +2.0 degrees, as required. Additionally, Entergy
WO [[]]
JF -929032800 dated January 10, 1992, stated that
RCIC flow indicator A13
FI -91@ was reading 50 gpm with the pump shutdown. This
WO was closed with no work performed. Approximately nine
WO s from 1994 to 2001 document various instances where
RCIC discharge flow indicators were showing flow with the
RCIC pump shutdown. Entergy entered the condition into their corrective action program and implemented interim corrective actions by revising the
RC [[]]

IC operating procedure to vent the sensing

lines. In addition, Entergy has scheduled activities to correct the instrument sensing line slope. The inspectors determined that the performance deficiency was that Entergy did not correct the inadequate sloping of the

RCIC instrument lines as specified in Equivalent Change
JE -01-141, resulting in
RCIC inoperability on May 4, 2006. Entergy procedure

EN-LI-102, "Corrective Action Process," Revision 10, requires, in part, that corrective actions address the cause or resolve the deficiency. This was reasonably within Entergy=s ability to foresee and prevent. Traditional enforcement does not apply because the issue did not have an actual safety consequence or a potential for

impacting the

NRC =s regulatory function, and it was not the result of any willful violation of
NRC [[requirements. Analysis: The inspectors determined that this finding was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems cornerstone, and it impacted the cornerstone objective of ensuring the availability, reliability, and capability of the]]
RCIC system to respond to initiating events to prevent undesirable consequences. The

RCIC system would not have been able to achieve its

design flow rate of 410 gpm. The inspectors evaluated this finding using Phase 1 of Inspection Manual Chapter 0609, Appendix A, ASignificance Determination of Reactor Inspection Findings for At-Power Situations,@ and determined it to be of very low safety significance (Green) because it was not associated with a design or qualification deficiency, it did not represent any actual loss of a system safety function, it did not represent the actual loss of a safety function of a single train for greater than its

Technical Specification allowed outage time, and it was not potentially risk significant due to a seismic, flooding, or severe weather initiating event. Enforcement: No violation of regulatory requirements occurred because corrective action issues related to the

RCIC System are outside of the scope of 10
CFR 50 Appendix
B. (Finding (

FIN)05000333/2007004-01, Failure to Correct Negative Slope of the Reactor Core Isolation Cooling System Flow Instrument Sensing Lines.) 1R13 Maintenance Risk Assessments and Emergent Work Control (71111.13 - 5 samples) a. Inspection Scope The inspectors reviewed maintenance activities to verify that the appropriate risk assessments were performed prior to removing equipment for work. The inspectors

7verified that risk assessments were performed as required by

10 CFR [[Part 50.65(a)(4), and were accurate and complete. When emergent work was performed, the inspectors verified that the plant risk was promptly reassessed and managed. The documents reviewed are listed in the Attachment. The review of the following activities represented five inspection samples. * Week of July 9, 2007, which included emergent work on 93 P1A1, 'A' emergency diesel generator (]]

EDG) fuel oil transfer pump; * Week of July 23, 2007, which included emergent work on 71T-4, normal station service transformer, to repair a terminal; * Week of August 13, 2007, which included emergent work on the 'B' low pressure coolant injection system inverter, emergent work on the torus vent valve, 27-AOV-118, and planned maintenance on the 'B' electro-hydraulic control pump; * Week of September 10, 2007, which included a manual reactor scram and emergent work on residual heat removal system strainers, normal service water strainers and intake screens; and * Week of September 17, 2007, which included EDG maintenance and emergent work on the 'A' emergency service water pump. b. Findings No findings of significance were identified. 1R15 Operability Evaluations (71111.15 - 5 samples) a. Inspection Scope The inspectors reviewed operability determinations to assess the acceptability of the evaluations; when needed, the use and control of compensatory measures; and

compliance with Technical Specifications (TS). The inspectors' review included a verification that the operability determinations were made as specified by

ENN -
OP -104, "Operability Determinations." The technical adequacy of the determinations was reviewed and compared to the
TS ,

UFSAR, and associated design basis documents. The documents reviewed are listed in the Attachment. The following evaluations were

reviewed and represented five inspection samples: *

Inspection Scope The inspectors observed and reviewed the following activities during the FitzPatrick scheduled maintenance outage from August 20, 2007 through August 22, 2007, to confirm that the Entergy had appropriately considered risk, industry experience, and previous site-specific problems in their outage plan. The documents reviewed are listed

in the Attachment. During the outage, the inspectors observed portions of the shutdown

9and cooldown and monitored licensee controls over the outage activities listed below. * The inspectors reviewed outage schedules and procedures and verified that Technical Specification required safety system availability was maintained, shutdown risk was considered, and that contingency plans existed to restore key safety functions such as electrical power and containment integrity. * The inspectors observed portions of the plant shutdown and cooldown and verified that the Technical Specification cooldown rate limits were not exceeded. * The inspectors periodically verified the proper alignment and operation of the shutdown cooling and reactor coolant makeup systems. * The inspectors observed portions of the reactor startup following the outage, and verified that safety-related equipment required for mode change was operable, containment integrity was set, and reactor coolant boundary leakage was within Technical Specification limits. b. Findings No findings of significance were identified. 1R22 Surveillance Testing (71111.22 - 4 samples) a. Inspection Scope The inspectors witnessed performance of surveillance tests and/or reviewed test data of

selected risk-significant

SSC s to assess whether the
SSC s satisfied
TS ,

UFSAR, Technical Requirements Manual, and Entergy procedure requirements. The inspectors verified: test acceptance criteria were clear, demonstrated operational readiness, and were consistent with design basis documents; test instrumentation had current calibrations and adequate range and accuracy for the application; and tests were

performed, as written, with applicable prerequisites satisfied. Upon surveillance test (ST) completion, the inspectors verified that equipment was returned to the status specified to perform its safety function. The inspectors evaluated the tests against the requirements in

4OA 1 Performance Indicator (

PI) Verification

a. Inspection Scope (71151 - 2 samples) The inspectors reviewed

PI data for the cornerstone listed below and used Nuclear Energy Institute 99-02, "Regulatory Assessment Performance Indicator Guidance," Revision 5, to verify individual

PI accuracy and completeness.

11 Cornerstone: Barrier Integrity * Reactor coolant system leak rate * Reactor coolant system specific activity The inspectors reviewed operator logs, plant computer data, and surveillance procedure

ST -40D, "Daily Surveillance and Channel Check," to verify the accuracy of Entergy's reported maximum reactor coolant system identified leakage for July 2006 to June 2007. b. Findings No findings of significance were identified. 4

OA2 Identification and Resolution of Problems .1 Review of Items Entered into the Corrective Action Program (CAP) a. Inspection Scope As required by Inspection Procedure 71152, "Identification and Resolution of Problems," and in order to help identify repetitive equipment failures or specific human performance

issues for follow-up, the inspectors performed a daily screening of all items entered into Entergy's

CAP. The review was accomplished by accessing Entergy's computerized database for
CR s and attending
CR screening meetings. In accordance with the baseline inspection modules, the inspectors selected

CAP items

across the initiating events, mitigating systems, and barrier integrity cornerstones for additional follow-up and review. The inspectors assessed Entergy's threshold for problem identification, the adequacy of the cause analyses, extent of condition review, operability determinations, and the timeliness of the specified corrective actions. The CRs reviewed are listed in the Attachment. b. Findings and Observations No findings of significance were identified. .2 Annual Sample: Emergency Diesel Generator System (71152 - 1 sample)

a. Inspection Scope The inspectors selected several corrective action issues for detailed review that were associated with the emergency diesel generator (EDG) system. The main focus was on the maintenance, performance, and corrective actions associated with the EDGs after

the 'B'

EDG tripped on over-speed during the start of its idle speed run as documented in

CR-2007-1858. These reports were reviewed to ensure that an appropriate evaluation was performed and appropriate corrective actions were specified. The

2inspectors evaluated the reports against the requirements of procedure

ENN -
LI -102, "Corrective Action Process," and
10 CFR [[Part 50, Appendix B. b. Findings and Observations No findings of significance were identified. The inspectors determined that the causal analysis, extent of condition review, and the timeliness of the specified recommendations and corrective actions were appropriate. 4]]

OA3 Event Followup (71153 - 1 sample) .1 Manual Reactor Scram Due to Lowering Intake Water Level a. Inspection Scope The inspectors observed control room personnel responding to an unexpected decrease in plant cooling water intake level on September 12, 2007, which required that a manual reactor scram be initiated. As part of the followup to the event, the inspectors reviewed plant chart recorders, compared requirements of off-normal procedures to observations

of operators' performance, monitored equipment performance, and discussed the event response with plant personnel. The documents reviewed are listed in the Attachment. b. Findings No findings of significance were identified. 4OA6 Meetings, Including Exit On October 4, 2007, the inspectors presented the inspection results to Mr. Kevin J. Mulligan and other members of his staff. The inspectors asked Entergy

whether any of the material examined during the inspection should be considered proprietary. No proprietary information was identified.
