SUBJECT: PILGRIM NUCLEAR POWER STATION - NRC INTEGRATED INSPECTION REPORT 05000293/2006003
Dear Mr. Balduzzi:
On June 30, 2006, the US Nuclear Regulatory Commission (NRC) completed an inspection atyour Pilgrim reactor facility. The enclosed integrated inspection report documents theinspection findings, which were discussed on June 30, 2006, with you and members of your staff.The inspection examined activities conducted under your license as they relate to safety andcompliance with the Commission's rules and regulations and with the conditions of your license.
The inspectors reviewed selected procedures and records, reviewed your emergency preparedness program, observed activities, and interviewed personnel.This report documents one NRC-identified finding of very low safety significance. The findinginvolved a violation of NRC requirements which was classified at Severity Level IV inaccordance with the NRC's Enforcement Policy. However, because of the very low safetysignificance and because the issue has been entered into your corrective action program, the NRC is treating the issue as a non-cited violation (NCV), in accordance with Section VI.A.1 ofthe NRC's Enforcement Policy. If you contest the NCV in this report, you should provide aresponse with the 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, D.C. 20555-0001; with copies to the Regional Administrator, Region I; the Director, Office of Enforcement, U.S. Nuclear Regulatory Commission, Washington, D.C. 20555-0001; and the NRC Resident Inspector at Pilgrim. In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and itsenclosures will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of the NRC's documentsystem (ADAMS).

FINDINGSIR 05000293/200603; 04/01-06/30/2006; Pilgrim Nuclear Power Station; Maintenance RiskAssessments and Emergent Work Control.The report covered a 13-week period of inspection by resident inspectors, an announcedinspection by a regional specialist in health physics, and in-office reviews of emergency plan
changes and grid reliability issues. One finding, which was a non-cited violation (NCV), wasidentified. The significance of most findings is indicated by their color (Green, White, Yellow,
Red) using
NUREG-1649, "Reactor Oversight Process," Revision 3, dated July 2000.A.Inspector Identified and Self-Revealing FindingsCornerstone: Mitigating Systems
Severity Level
- IV Non-Cited Violationassociated with the licensee's failure to perform an adequate safety evaluation per
CFR 50.59, a screening safety evaluation for handling
of a 35 ton cask in the Reactor Building did not provide an adequate basis to
demonstrate that the evaluation for use of a heavier cask did not change theevaluation methods approved by the
- UFS [[]]
AR and the Pilgrim licensingbasis. The licensee made significant enhancements to the original 50.59 safety
evaluation and entered this issue into the corrective action program.The finding was determined to be more than minor because the inspectors could notreasonably determine that the methodology used to evaluate the use of a heavier caskdid not constitute a change that would have required NRC approval. The conditionsassociated with the finding (i.e., the potential drop of a loaded cask) were determined
to be of very low safety significance because they did not result in the loss of
operability of a safety system. Because the issue affected the NRC's ability to performits regulatory function, this finding was evaluated using the traditional enforcement
process and was classified at Severity Level
CFR 50.59
involved conditions evaluated as having very low safety significance by the SDP. This
finding has a cross-cutting aspect in the area of human performance because Entergy
did not fully evaluate the licensing basis to develop the 50.59 safety evaluation, andthereby failed to assure a design document was complete and accurate.

- REPORT [[]]
DETAILSSummary of Plant StatusPilgrim Nuclear Power Station operated at 100 percent (%) core thermal power for the entirereport period, except for short periods of planned operation at reduced power for routine
testing and maintenance.1.REACTOR
- SAFET [[]]
YCornerstones: Initiating Events, Mitigating Systems, and Barrier Integrity1R04Equipment Alignment (71111.04).1Partial System Walkdowns c.Inspection Scope (4 samples) The inspectors completed a partial system review of the risk significant systems listedbelow to determine whether the systems were correctly aligned to perform theirdesigned safety function. The position of key valves, breakers, and control switches
required for system operability were verified by field walkdown and/or review of themain control board indicators. To ascertain the required system configuration, theinspectors reviewed plant procedures, system drawings, the Updated Final SafetyAnalysis Report (UFSAR), and the Technical Specifications (TS). The references
used for this review are listed in the attachment to this report. This inspection activity
represented four samples.*High pressure core injection (HPCI) system during reactor core isolationcooling (RCIC) testing on April 11-12, 2006;*Residual heat removal (RHR) "A" and "B" trains, following maintenance andtesting on April 24, 2006;*RCIC system during
EDG) during "A" EDG maintenance on June 14, 2006. b.FindingsNo findings of significance were identified.
2Enclosure1R05Fire Protection (71111.05).1 Quarterly Fire Protection Inspection a.Inspection Scope (9 samples) The inspectors toured selected areas of the plant to observe conditions related to:
(1) transient combustibles and ignition sources; (2) fire detection systems; (3) manualfirefighting equipment and capability; and (4) passive fire protection features. The inspectors verified adequate material condition of active and passive fire
protection systems features and their operational line up and readiness. Theinspectors also reviewed the applicable fire hazard analysis fire zone data sheets.
The references used for this review are listed in the attachment to this report. This
inspection activity represented nine samples.*Fire Zone 1.16, Reactor Building Open Area at El. 91, North Half;*Fire Zone 1.20, Refueling Floor;
- Fire Zone 1.18, Contaminated Equipment and Skimmer;
- Fire Zone 1.17, Clothing Change Area;
- Fire Zone 1.15, Standby Liquid Control;
- Fire Zone 1.10B, B
HPCI Pipe Room;*Fire Zone 2.1, B Switchgear and Load Center Room;
- Fire Zone 4.1, B Train Diesel Generator Room; and
- Fire Zone 4.2, B Train Diesel Day Tank Room. b. FindingsNo findings of significance were identified..2Annual Fire Drill Observation n.Inspection Scope (1 sample)The inspectors observed a training fire drill conducted on April 28, 2006 per procedure1.4.23, "Fire Brigade Training Drill." The unannounced drill involved a simulated fire inthe onsite two-story Butler Building, which contained a simulated radiologically
controlled area. The unannounced drill involved the combined response of the onsitefire brigade (FB) and the Plymouth Fire Department (PFD). The inspectors observed
fire personnel performance, and confirmed that the licensee's fire fighting pre-plan
strategies per procedure 5.5.2, "Special Fire Fighting Procedure," were utilized, thepre-planned drill scenario was followed, and the drill objectives were met. Theinspectors verified the joint use of the Incident Command System by the
PFD.
The inspectors confirmed that proper security and radiological controls were applied;
proper protective clothing and breathing apparatus were donned; sufficient fire fightingequipment was brought to the scene; the fire brigade leader's fire fighting directions
were clear; and communications with the plant operators and between fire brigade
members were effective. The inspectors confirmed the drill critique identified areas to
3Enclosureenhance fire brigade performance. The inspectors verified that the licensee identifiedappropriate corrective actions for identified deficiencies and entered the issues into
the corrective action program. This activity represented one inspection sample. o.FindingsNo findings of significance were identified.1R11Licensed Operator Requalification (71111.11).1Licensed Operator Simulator Training a. Inspection Scope (1 sample)The inspectors observed the performance of an operator crew during a simulatortraining session on May 11, 2006. The training was conducted as part of licensed
operator just-in-time (JIT) training for the planned movement of a 35 ton shipping cask
inside the reactor building. Licensee evaluations in
- UFS [[]]
AR Section 10.3.6 concluded
that the postulated drop of the shipping cask could constitute a severe plant event thatwould result in an operational transient and impact plant safety systems. Theinspectors verified the JIT training scenario developed was adequate to ensure the
crew's ability to safely shutdown the plant. The inspectors evaluated whether the crew
met the training scenario objectives, performed the critical tasks, and properly usedabnormal operating procedures and emergency operating procedures. The inspectors
verified that the post-scenario critique discussed items for improvement with the crew
to enhance performance. The references used for this review are listed in the
attachment to this report. This inspection activity represented one sample. b.FindingsNo findings of significance were identified..2Licensed Operator Simulator Exams a.Inspection Scope (1 sample)The inspectors observed an evaluated licensed operator simulator training exercise onMay 22, 2006. The training was performed using scenario SES-00-00-152 and
involved both operational transients and design basis events. The inspectors
evaluated both the crew's performance and evaluators' assessments. Specifically, the
inspectors evaluated whether the crew met the scenario objectives, accomplished the
critical tasks, demonstrated proper use of abnormal and emergency operatingprocedures, demonstrated proper command and control, communicated effectively,
and implemented the emergency plan in-terms of event classification and notification. The inspectors reviewed the post-scenario critique and confirmed lessons learned and
items for improvement were discussed with the crew to enhance future performance.
4Enclosure b.FindingsNo findings of significance were identified.1R12Maintenance Rule (71111.12) a.Inspection Scope (3 samples)The inspectors reviewed follow-up actions for issues relating to the selected systemsand reviewed the performance history of the systems to assess the effectiveness ofEntergy's maintenance activities. The inspectors reviewed Entergy's problem
identification and resolution actions for these issues in accordance with NRC
procedures and the requirements of 10 CFR 50.65(a)(1) and (a)(2), "Requirements for
Monitoring the Effectiveness of Maintenance." In addition, the inspectors reviewed
system classification, performance criteria and goals, system health reports, andcorrective actions that were taken or planned to verify whether the actions were
reasonable and appropriate. These inspection activities represented three samples: *Proper classification of equipment issues for System 50 - PrimaryContainment, including the Operational Decision Management Issue (ODMI)
for drywell leakage (Condition Report (CR) 200503299). The inspectors
reviewed Entergy's basis for placing the system in maintenance rule (a)(2)status.*Proper classification of equipment issues for System 54 - Reactor PressureVessel, including the core shroud tie down bolts (CR 200601849). *The inspectors reviewed Entergy's basis for placing the system in maintenancerule (a)(2) status.*Proper classification of equipment issues for System 66 - Process RadiationMonitors C19A/B. The inspectors reviewed Entergy's basis for placing the
system in maintenance rule (a)(2) status. b.FindingsNo findings of significance were identified.1R13Maintenance Risk Assessments and Emergent Work Control (71111.13) a.Inspection Scope (5 samples)The inspectors evaluated on-line risk management for planned and emergent work. The inspectors reviewed maintenance risk evaluations, work schedules, recent
corrective actions, and control room logs to verify that other concurrent planned and
emergent maintenance or surveillance activities did not adversely affect the plant riskalready incurred with the out-of-service components. The inspectors evaluated
whether Entergy took the necessary steps to control work activities, took actions to
minimize the probability of initiating events, and maintained the functional capability ofmitigating systems. The inspectors assessed Pilgrim's risk management actions
5Enclosureduring plant walkdowns. The inspectors also discussed risk management activitieswith maintenance, engineering and operations personnel as applicable. References
used for the inspection are identified in the attachment to this report. The inspectioncovered the following five samples: *The elevated (Yellow) risk associated with the
- RHR logic system functional teston April 17, 2006;*The elevated (Yellow) risk condition on May 11, 2006, associated with logicsystem functional test of the "A"
- RHR system;*The elevated (Orange) risk associated with the inspection of salt service waterpump P208E per maintenance request (
MR) 06107824 on June 1, 2006;*The elevated (Yellow) risk condition the week of June 11 for plannedmaintenance activities on the A emergency diesel generator; and*The risk associated with the control of heavy loads while handling a CNS 3-55waste shipment cask in the Reactor Building as part of the spent fuel pool
cleanup activities: MR 05118433, "Clean Spent Fuel Pool, Ship Irradiated
Hardware;" and, engineering request (ER) 05120679, "Provide
CNS 3-55 Shipping Cask and
the Crusher Shearer Tool and Stand to be used in the Fuel Pool Cleanup
Project." b.FindingsIntroduction:The inspectors identified a Severity Level
- IV Non-Cited Violation associated with thelicensee's failure to perform an adequate safety evaluation (
UFSAR describes the methods for controlling heavy loads and theevaluations used to determine the consequences of a dropped cask in the spent fuel
pool. The methods were described in License Amendments 20, 24 and 29, which
were incorporated in
NRC requests foradditional information in 1980, the licensee described additional evaluations and
methods to meet the
- NUREG 0612 criteria to control heavy loads and mitigate theconsequences of a cask drop event. The evaluations were described in letters to
- SE dated March 6, 1985. The 1981 and1983 evaluations became part of the licensing basis established in
- UFS [[]]
AR Sections
10.3.6 and 12.2.3.7 as the methods accepted by the
- NUREG 0612 licensing basis included a shippingcask with a loaded weight of 26 tons.Entergy planned to use a
- CNS 3-55 shipping cask to transport radioactive waste fromPilgrim Station during a spent fuel pool clean-up project in 2006. The
CNS 3-55 cask
6Enclosurehas a maximum loaded weight of 35 tons. The licensee completed
NUREG 0612compliance addressed a spent fuel shipping cask with a loaded weight of 26 tons.
Since the proposed
NUREG 0612 compliance." ER 05120679 further defined requirementsto assure that equipment and procedures used for the spent fuel pool cleanup were in
accordance with the
- NUREG 0612 licensing commitments regarding safe load paths,lifting devices and load drop consequences.Entergy performed a 10
- ER 05120679, dated March24, 2006. Entergy concluded that a complete 50.59 evaluation was not requiredbecause the proposed activity screened out based on a determination that
- UFS [[]]
AR or used in
establishing the licensing basis. The inspector identified several issues which
indicated ER 05120679 had made changes to the evaluation methods used in the
licensing basis approved by the
NRC concerns involved the movement of the cask in and out of the spent fuel pooland the movement of the cask across the operating floor. To evaluate the move of theCNS 3-55 cask across the refueling floor, ER 05120679 used energy balance
methods to conclude that handling the 35 ton cask at a height of four inches above thefloor was equivalent to the licensing basis of handling the 26 ton cask at six inches.
ER 05120679 prescribed the use of wood cribbing to maintain the four inch distance
when lifting the cask above interferences around the periphery of the spent fuel pool.
ER 05120679 relied upon a 1993 analysis to evaluate spent fuel pool integrity
following a cask drop. The 1993 methodology had not received previous
NUREG 0612 evaluations. Further, the 1993 analysiscredited an impact limiter (Hexcel energy absorbing pad) in evaluating the cask drop
consequences. The use of an energy absorber pad had not been reviewed by the
NUREG 0612 evaluations.The inspectors' concerns were reviewed with licensee staff in meetings on March 24,April 6, April 7, May 5 and May 10, 2006. In response, the licensee first added detailsto the bases for the 10 CFR 50.59 screening, and then further researched the
complete licensing basis for the control of heavy loads which was incorporated into a
full 50.59 safety evaluation. The safety evaluation was issued in
3402 Revision 1, dated May 10, 2006. Following a review on May 10, the inspectors
concluded the safety evaluation dated May 10, 2006 fully described the licensing
basis, showed the relevance of the 1993 analysis without relying on it for the
- NUR [[]]
EG0612 commitments, and showed that a 35 ton cask and the Hexcel pad had been
described in the licensing basis for the control of heavy loads. The licensee entered
this issue into the corrective action program as CR 200602460.
7EnclosureAnalysis:A performance deficiency was identified in that Entergy had not developed an adequatebasis to support the 10 CFR 50.59 screening safety evaluation dated March 24, 2006.
The March
ER 05120679 was inadequate because it did not fully describe
the complete licensing basis for the control of heavy loads, and it used evaluation
methods different than those approved by the
NUREG 0612. The finding was determined to be more than minorbecause the inspectors could not reasonably determine that the methodology used toevaluate the use of a heavier cask did not constitute a change that would have required
NRC approval. The conditions associated with the finding (i.e., the potential drop of aloaded cask) affected the objective of the Mitigating Systems cornerstone to ensure the
availability of systems to respond to events. The conditions were assessed using theSDP and determined to be of very low safety significance because they did not result in
the loss of operability of a safety system. Because the issue affected the NRC's abilityto perform its regulatory function, this finding was evaluated using the traditional
enforcement process and was classified at Severity Level IV because the violation of
CFR 50.59 involved conditions evaluated as having very low safety significance by
the
- SDP.T his finding has a cross-cutting aspect in the area of human performance becauseEntergy did not fully evaluate the licensing basis to develop the 10
- UFSAR toinclude changes to evaluations that demonstrate that intended functions will beaccomplished. 10
- CFR 50.59(c)(1) states a licensee may make changes to the facilityand procedures as described in the
- UFS [[]]
AR without obtaining a license amendment
pursuant to 10 CFR 50.90 only if the change does not meet any of the criteria in
paragraph (c)(2).
CFR 50.90 prior to implementing a proposed change if the
change results in a departure from a method of evaluation described in the
- UFS [[]]
used in establishing the design bases. 10 CFR 50.59(a)(2)(ii) defines departures from
a method of evaluation as changing a method described in the
- UFS [[]]
AR to another
method, unless that method has been approved by
CFR 50.59(d)(1) requires a written evaluation which provides the bases for the
determination that the change does not require a license amendment. Contrary to the above, in a 50.59 screening evaluation for ER 05120679, datedMarch 24, 2006, Entergy failed to provide an adequate basis for the determination thatthe handling of heavy loads for the spent fuel pool cleanup project did not result in a
change in the
IV and has been entered into Entergy's corrective action program
(CR 200602460), this violation is being treated as a Non-Cited Violation (NCV),
8Enclosureconsistent with Section
NRC Enforcement Policy. NCV 0500293/2006003-001: Failure to perform an adequate 50.59 evaluation for the control of heavy
loads.1R15Operability Evaluations (71111.15) a.Inspection Scope (4 samples)The inspectors reviewed selected operability determinations to assess the adequacy ofthe evaluations, the use and control of compensatory measures, compliance with the
Technical Specifications, and the risk significance of the issues. The inspectors used
the Technical Specifications,
- UFS [[]]
OP-104 "Operability Determinations," and the additional references listed in theattachment to this report for Section 1R15. This review covered four inspection
samples:*CR 200601849, General Electric Safety Communication 06-07, Core ShroudRepair Tie Rod Upper Support Cracking;*CR 200602122, Station blackout diesel generator jacket water expansion tankcontains small amount of oil;*CR 200602271, "A" EDG gear box back lash out-of-tolerance; and
- CR 200602222, "A" EDG inner and outer slip ring tolerance out-of-tolerance.The inspectors verified Entergy was identifying problems with operability determinationsat an appropriate threshold and entering them into the corrective action program. b.FindingsNo findings of significance were identified.1R19Post-Maintenance Testing (71111.19) a.Inspection Scope (7 samples)The inspectors reviewed post-maintenance test activities on risk significant systems toverify that the effect of the test on the plant had been evaluated adequately, the testwas properly performed in accordance with procedures, the test data met the required
acceptance criteria, and the test activity was adequate to verify system operability andfunctional capability following maintenance. The inspectors confirmed that systemswere properly restored following testing and that discrepancies were appropriately
documented in the corrective action process. The inspection activity representedseven samples:*Replacement of

with the written procedure, the test data was complete and met procedural
requirements, and the components were capable of performing their intended safety
functions. The inspection activity represented eight samples:*2.1.15,

10Enclosure b.FindingsNo findings of significance were identified.1R23Temporary Plant Modifications (71111.23) a.Inspection Scope (1 sample) The inspectors reviewed Temporary Alteration 06-1-08 to verify that the licensing basesand performance capability of the associated risk significant system had not beendegraded through the modification. The references used for this review are listed in the
attachment to this report. This inspection activity represented one sample.Temporary Alteration 06-1-08 installed a temporary 24 vdc power system for theneutron monitoring and process radiation monitoring instrumentation while replacing
the existing 24 volt batteries. The licensee provided an analysis as part of the technical
justification for TA 06-1-08. The inspectors discussed the temporary alteration with
licensee personnel and observed work activities in progress. The inspectors reviewed
the controls used by the licensee to assure the 24 vdc system remained operable. The inspectors reviewed the changes to applicable plant drawings and confirmed the
modifications were installed per TA 06-1-08. b. FindingsNo findings of significance were identified.
Cornerstone: Emergency Preparedness1EP4Emergency Action Level and Emergency Plan Changes (71114.04) a.Inspection Scope (1 sample)An in-office inspection to review recent changes to the Pilgrim Nuclear Power StationEmergency Plan (revision 32) was conducted on June 22 - 23, 2006. These changes
were made in accordance with 10 CFR 50.54(q). The licensee had determined that the
changes did not decrease the effectiveness of the Plan and concluded that the Plancontinued to meet the requirements of
CFR 50. During this inspection, the inspectors conducted a sampling review of the changes that
could potentially result in a decrease in effectiveness. This review did not constitute an
approval of the changes and, as such, the changes are subject to future
CFR 50.54(q)were used as reference criteria.
11Enclosure b.FindingsNo findings of significance were identified.1EP6Drill Evaluation (71114.06).1Event Classification During Operator Simulator Training b.Inspection Scope (1 sample) The inspectors observed an evaluated licensed operator simulator training exercise onMay 22, 2006, and evaluated the crew's ability to implement the emergency plan. Specifically, the inspectors confirmed the crew properly classified the event, activated
the notification system, and appropriately completed and transmitted the eventnotification forms in a timely manner. c.FindingsNo findings of significance were identified..2Combined Functional Drill a.Inspection Scope (1 sample) The inspectors reviewed the combined functional drill scenario (06-01) conducted onJune 1, 2006, and observed portions of the drill at the technical support center and theemergency operation facility. The inspection focused on the ability of Entergypersonnel to properly conduct classification, notification, and protective action
recommendation activities, and on the evaluators' ability to identify observedweaknesses and/or deficiencies within these areas. The inspectors attended the player
post-drill critiques to compare NRC identified deficiencies against the licensee'sidentified findings to determine whether Entergy was properly identifying weaknesses in
these areas. The inspectors reviewed licensee actions to address issues in the
corrective action program. The references used in this review included the Controller
Manual Combined Functional Drill (06-01) dated June 1, 2006. b.FindingsNo findings of significance were identified.
2Enclosure2.RADIATION
PS1Radioactive Gaseous and Liquid Effluent Treatment and Monitoring Systems(7112201) a.Inspection Scope (10 samples)The inspectors reviewed the most current Pilgrim Nuclear Power Station RadiologicalEffluent and Waste Disposal Report to verify that the program was implemented as
described in the Radiological Effluent Technical Specification/Offsite Dose Calculation
Manual (RETS/ODCM). The inspectors reviewed the report for significant changes to
the
- NUR [[]]
EG-0133 and were technically justified and documented, and to determinewhether the modifications made to radioactive waste system design and operationchanged the dose consequence to the public. The inspectors also verified that
technical and design change reviews, such as 10 CFR 50.59 reviews, were performed
as required and determined whether radioactive liquid and gaseous effluent radiation
monitor setpoint calculation methodology changed since completion of the
modifications. The inspectors also reviewed the report to assure that any anomalous
information was effectively reported and explained. The inspectors reviewed the
ODCM to identify the effluent radiation monitoring systems and associated flowmeasurement devices; reviewed effluent radiological occurrence performance indicator
incidents for onsite follow-up; and reviewed licensee self assessments, audits, and
licensee event reports that involved unplanned releases of radioactive material. The
inspectors noted there had been no changes made by the licensee to the
- OD [[]]
CM or to
the liquid or gaseous radioactive waste system design or operation since the lastinspection in 2004. The inspectors walked down the major components of the gaseous and liquid releasesystems (e.g., radiation and flow monitors, demineralizers and filters, tanks, andvessels) to observe ongoing activities, current system configuration with respect to thedescription in the
- UFS [[]]
AR, and equipment material condition. The inspectors reviewed the liquid discharge permit used since the previous inspection,including the projected doses to members of the public. The inspectors also observed
the routine sample collection and analysis for the continuous release of radioactive
gaseous effluent to verify that appropriate treatment equipment was effectively used
and that the radioactive gaseous effluent was processed and released in accordance
with
ODCM requirements. The inspectors reviewed the release records to
confirm that adequate controls were in place to prevent an unmonitored or
unanticipated release of radioactive material to the environment.
13EnclosureThe inspectors reviewed a selection of monthly, quarterly, and annual dose calculationsto ensure that the licensee had properly calculated the offsite dose from radiological
effluent releases and to determine if any annual Technical Specification/ODCM (i.e.,
Appendix I to
PI report
was issued.The inspectors reviewed air cleaning system surveillance test results and licenseespecific methodology to ensure that the system was operating within the licensee'sacceptance criteria. The inspectors also reviewed surveillance test results and the
methodology the licensee uses to determine the stack and vent flow rates and
evaluated whether the flow rates are consistent with
- UFS [[]]
AR values. The inspectors reviewed records of instrument calibrations performed since the lastinspection for each point of discharge effluent radiation monitor and flow measurement
device, and reviewed any completed system modifications and the current effluentradiation monitor alarm setpoint value for agreement with
ODCM requirements.
The inspectors also reviewed calibration records for radiation measurement
(i.e., counting room) instrumentation associated with effluent monitoring and release
activities and reviewed quality control records for the radiation measurement
instruments. The inspectors reviewed the results of the interlaboratory comparison program to verifythe quality of radioactive effluent sample analyses performed by the licensee; reviewed
the licensee's quality control evaluation of the interlaboratory comparison test and
associated corrective actions for any deficiencies identified; and reviewed the results
from the licensee's

PI data to
confirmatory plant records and data available in plant logs, the chemistry data base
(WinCDMS), maintenance rule records, Licensee Event Reports, condition reports and
NRC inspection reports. The inspection activity represents three samples.*Mitigating System Cornerstone, Safety System Functional Failures from thethird quarter of 2004 through first quarter of 2006;*Barrier Integrity Cornerstone, Reactor Coolant System Specific Activity from thethird quarter of 2004 through the first quarter 2006; and*Barrier Integrity Cornerstone, Reactor Coolant System Unidentified Leakagefrom the third quarter of 2004 through the first quarter 2006. b.FindingsNo findings of significance were identified.
15Enclosure.2Public Radiation Safety Cornerstone a. Inspection Scope (1 sample)The inspectors sampled licensee data for the
- PI. [[]]
PI definitions and guidance contained in NEI 99-02, "Regulatory
Assessment Indicator Guideline," Rev. 2, were used to verify the accuracy of the PI
data reported.The inspectors reviewed the Radiological Control Effluent Release Occurrences PIresults for the Public Radiation Safety Cornerstone. For the assessment period, the
inspectors reviewed selected out of service effluent radiation monitor and
compensatory sampling data, any abnormal release results as reported in the 2004 and
2005 Annual Effluent Reports, procedural guidance for reporting PI information, and
selected condition reports related to
ODCM issues. In addition, the inspectors
reviewed cumulative and projected doses to the public for the period October 2004
through May 2006. Documents reviewed are listed in sections
OA1 of the
report attachment. b. FindingsNo findings of significance were identified.4OA2Identification and Resolution of Problems (71152)1.Routine Review of Corrective Action Program Issues a.Inspection ScopeAs required by Inspection Procedure 71152, "Identification and Resolution ofProblems," the inspectors performed a screening of each item entered into Entergy's
corrective action program. This review was accomplished by reviewing printouts of
each condition report, attending daily screening meetings and/or accessing Entergy's
database. The purpose of this review was to identify conditions such as repetitive
equipment failures or human performance issues that might warrant additional follow-
up. b.FindingsNo findings of significance were identified. 2.Corrective Action Program Semi-annual Trend Review a.Inspection ScopeAs required by Inspection Procedure 71152, "Identification and Resolution ofProblems," the inspectors performed the semi-annual trend review to identify trends,
16Enclosureeither Entergy or NRC identified, that might indicate the existence of a more significantsafety issue. Included within the scope of this review were condition reports from
October 2005 through June 2006, the 4th quarter 2005 corrective action trend reports,and the daily plant status report listings of operations equipment problems, operabilityevaluations, and temporary alterations. b. Findings and ObservationsNo findings of significance were identified. Several trends were identified, but nonethat suggested the presence of a more significant safety issue. The majority of the
trends identified by the inspectors had been recognized by Entergy and captured in
adverse trend
CR 2005-4706) which is being evaluated by Entergy. The inspectors
identified that adverse trends noted by Entergy in the areas of communication
equipment and meteorological tower performance appear to be further degrading.
Adverse trends not captured by the current licensee trend report were noted regarding
augmented off-gas system spikes and/or pre-treat
- HI [[]]
RAD alarms, expiredchemicals/reagents in the chemistry lab, and water in the station blackout fuel oil
storage tanks. The licensee noted these items for further consideration. .3Annual Sample Review - Operator Workarounds a.Inspection Scope (1 sample)The inspectors reviewed the cumulative effect of operator workarounds on thereliability, availability, and potential mis-operation of systems with particular focus onissues that had the potential to affect the ability of operators to respond to planttransients and events. The inspectors reviewed the Operator Compensatory MeasureLog, the Operator Aggregate Impact Index for April 2006, and Operations PerformanceIndicators, as well as the related operator workarounds, operator burdens, control room
deficiencies, system lineup deviations, protective and caution tagouts, and disabled orilluminated control room alarms. For selected issues, the inspectors discussed the
issues with responsible operations personnel to ensure they were appropriately
categorized, prioritized and tracked for resolution. b.Findings and Observations No findings of significance were identified. The inspectors found that Entergy ensuredthat appropriate attention was placed on conditions that could impact operator actions,including conditions that would require compensatory actions
(workarounds and burdens), control room deficiencies and alarms, and components
tagged out-of-service or with caution tags, through periodic management review of
performance indicators. Appropriate actions were taken to ensure that operators were
aware of the issues, and corrective actions were scheduled for completion
commensurate with each item's significance.

operational readiness of offsite power systems and impact on plant risk. The inspectorsevaluated licensee procedures against the specific offsite power, risk assessment and
system grid reliability requirements of
- TI 2515/165. They also discussed the attributeswith licensee personnel. The information gathered while completing this
TI was forwarded to the Office ofNuclear Reactor Regulation for further review and evaluation on April 3, 2006. b.FindingsNo findings of significance were identified..2Strike Contingency Planning (92709) a.Inspection Scope (1 sample)Entergy developed a staffing contingency plan to continue Pilgrim Station securityoperations should union personnel engage in a job action. Using the guidance of
Inspection Procedure 92709, the inspectors reviewed licensee plans to address a
potential job action. The inspection included an evaluation of the strike contingency
plan content and the actions needed to implement the plan; and, a review to determine iffacility security would be maintained as required with a sufficient number of qualifiedpersonnel. NRC review of this area continued at the end of the inspection.
