SUMMARY OF FINDINGS
IR 05000293/2012002; 01/01/2012 - 03/31/2012; Pilgrim Nuclear Power Station; Maintenance Effectiveness.
This report covered a three-month period of inspection by the resident inspectors and announced inspections performed by regional inspectors. The inspectors identified one finding of very low safety significance (Green), which was a non-cited violation (NCV).
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 the finding was determined using IMC 0310, "Components Within the Cross-Cutting Areas."
Findings for which the SDP does not apply may be Green, or may 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.
Cornerstone: Mitigating Systems
- Green.
The inspectors identified an NCV of very low safety significance (Green) of 10 CFR Part 50.65, "Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants," because Entergy did not include the Rod Worth Minimizer (RWM) system into the scope of Maintenance Rule (MR) systems. Specifically, Entergy did not include the RWM system into the scope of the MR monitoring program as required by 10 CFR 50.65 (b)(2)(i) as a non-safety related system that is relied upon to mitigate accidents or transients. Entergy entered this issue in the corrective action program (CR-PNP-2012-0394).
The inspectors performed a review of IMC 0612, Appendix E, "Examples of Minor Issues," and determined the issue was more than minor because it was similar to example 7.d; in that, the RWM system was not within the scope of the Maintenance Rule and that equipment performance problems were such that effective control of performance could not be demonstrated. The finding was also determined to be more than minor because it is associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and affected the availability of the RWM to provide its mitigation function for a control rod drop accident (CRDA). This finding had a cross-cutting aspect in the Problem Identification and Resolution cross-cutting area, Self Assessment component, because previous assessments performed by Entergy did not include Maintenance Rule scoping attributes nor did they identify scoping issues such as the RWM system. P.3(a) (Section 1R12)
REPORT DETAILS
Summary of Plant Status
Pilgrim Nuclear Power Station began the inspection period during a power ascension to 100 percent reactor power following a December 2011 forced outage. On January 1, Pilgrim returned to 100 percent reactor power. On February 23, operators reduced reactor power to 47 percent to perform a thermal backwash of the main condenser and to perform repairs on main steam isolation valve '2B'. On February 24, Pilgrim returned to 100 percent reactor power. On February 25, operators reduced power to 90 percent to perform a control rod pattern adjustment. Pilgrim returned to 100 percent reactor power later that same day. On March 14, operators reduced power to 65 percent to perform deep and shallow control rod testing, and a subsequent control rod pattern adjustment. Pilgrim returned to 100 percent reactor power later that same day and operated at or near 100 percent reactor power for the remainder of the inspection period.

b. Findings
Introduction.
The inspectors identified an NCV of very low safety significance (Green) of 10 CFR Part 50.65, "Requirements for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants," because Entergy did not include the RWM system into the scope of MR systems. Specifically, Entergy did not include the RWM system into the scope of the MR monitoring program as required by 10 CFR 50.65 (b)(2)(i) as a non-safety related system that is relied upon to mitigate accidents or transients.
Description.
During low power operations, Pilgrim's RWM enforces specific control rod sequences designed to mitigate the consequences of the CRDA by providing control rod blocks to the reactor manual control system. Per Pilgrim's Technical Specification (TS)
Basis document, the RWM enforces the banked position withdrawal sequence below 20 percent reactor thermal power to ensure enthalpy addition due to a potential CRDA does not exceed 280 cal/gm, which is the threshold for fuel damage. Furthermore, Pilgrim's Final Safety Analysis Report (FSAR), Section 14.5, "Postulated Design Basis Accidents,"
assumes the reactor is to be at a control rod pattern corresponding to the maximum incremental worth. It credits a functional RWM in this assumption. The inspectors identified, however, that the RWM was not included within the scope of the MR at Pilgrim. The inspectors also reviewed previous MR assessments, including the prior cycle 10 CFR 50.65 paragraph a(3) assessment, and identified that the evaluation of MR scoping was not an attribute included in these assessments. Additionally, the RWM has had a history of extended unavailability from June to December 2011 and January to March 2012. This history of equipment unavailability does not show effective system performance or condition monitoring through appropriate preventive maintenance activities. Entergy generated CR-PNP-2012-0394 to identify that the RWM system is not scoped in the MR under the consideration of non-safety related systems relied upon to mitigate accidents or transients, utilizing procedure EN-DC-204, "Maintenance Rule Scope and Basis."
Analysis.
The inspectors identified a performance deficiency in that Entergy personnel did not recognize the need to include the RWM system in the MR when it was credited to
mitigate the consequences of a CRDA. Traditional enforcement does not apply since there were no actual safety consequences, impacts on the NRC's ability to perform its regulatory function, or willful aspects of the finding. The inspectors performed a review of IMC 0612, Appendix E, "Examples of Minor Issues," and determined the issue was more than minor because it was similar to example 7.d; in that, the RWM system was not within the scope of the Maintenance Rule and that equipment performance problems were such that effective control of performance could not be demonstrated. The finding was also determined to be more than minor because it is associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and affected the availability of the RWM to provide its mitigation function for a CRDA.
The inspectors conducted a Phase 1 screening in accordance with NRC Inspection Manual Chapter (IMC) Attachment 0609.04, "Phase 1 - Initial Screening and Characterization of Findings," and determined that the finding was of very low safety significance (Green) because the finding was not a design or qualification deficiency that did not result in loss of operability, did not represent an actual loss of system safety function, did not represent an actual loss of safety function of a single train for greater than its TS allowed outage time, did not represent an actual loss of safety function of one or more non-technical specification trains of equipment designated as risk significant 9 Enclosure per 10 CFR 50.65, and did not screen as risk significant due to a seismic, flooding, or severe weather initiating event. This finding had a cross-cutting aspect in the Problem Identification and Resolution cross-cutting area, Self Assessment component, because previous assessments performed by Entergy did not include MR scoping attributes nor did they identify scoping issues such as the RWM system. P.3(a)
Enforcement.
10 CFR Part 50.65, "Requirements for Monitoring the Effectiveness of Maintenance of Nuclear Power Plants," requires, in part, that the scope of the monitoring program include non-safety related structures, systems, or components that are relied upon to mitigate accidents or transients. Contrary to the above, Entergy did not scope the RWM's function to mitigate a CRDA into the Maintenance Rule. Entergy's corrective actions included evaluating the RWM for inclusion into the Reactor Manual Control System Maintenance Rule Basis Document. Because this finding is of very low safety significance, and Entergy has entered it into their corrective action program (CR-PNP-2012-0394), this violation is being treated as an NCV, consistent with the NRC's Enforcement Policy. (NCV 05000293/2012002*01, Failure to Scope the Rod Worth Minimizer into the Maintenance Rule)
1R13 Maintenance Risk Assessments and Emergent Work Control
a. Inspection Scope
The inspectors reviewed station evaluation and management of plant risk for the maintenance and emergent work activities listed below to verify that Entergy performed the appropriate risk assessments prior to removing equipment for work. The inspectors selected these activities based on potential risk significance relative to the reactor safety cornerstones. As applicable for each activity, the inspectors verified that Entergy personnel performed risk assessments as required by 10 CFR 50.65(a)(4) and that the assessments were accurate and complete. When Entergy performed emergent work, the inspectors verified that Operations personnel promptly assessed and managed plant risk. The inspectors reviewed the scope of maintenance work and discussed the results of the assessment with the station's probabilistic risk analyst and Operations personnel to verify plant conditions were consistent with the risk assessment. The inspectors also reviewed the TS requirements and inspected portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable
requirements were met.
- Emergent Orange Risk with both the Station Blackout Diesel Generator and the 'B' Emergency Diesel Generator Unavailable
- Green Risk during Planned Condensate Storage Tank Surveillance Testing with Increased Trip Risk
- Green Risk for the Shutdown Transformer being fed from Line 71 and MSIV 2B DC solenoid out-of-service
- Green Risk due to a Degraded Power Supply to the Shutdown Transformer
- Qualitative Yellow Risk Associated with Removing Both Trains of the Standby Gas Treatment System
- Yellow Risk for Analog Trip System Testing
10 Enclosure
b. Findings
No findings were identified.
1R15 Operability Determinations and Functionality Assessments
a. Inspection Scope
The inspectors reviewed operability determinations for the following degraded or non-conforming conditions:
- Drywell to Torus differential pressure could not be established while performing Vacuum Breaker Operability Test
- High Pressure Coolant Injection Room Coolers powered off the same AC electrical bus
- Reactor Core Isolation Cooling System Pre-Alarm Low Set Point Actuation
- Reactor Core Isolation Cooling Steam Supply Drain Valve and/or Strainer not Functioning Properly
- Station Blackout Diesel Generator Breaker Failure to Open The inspectors selected these issues based on the risk significance of the associated components and systems. The inspectors evaluated the technical adequacy of the operability determinations to assess whether TS operability was properly justified and the subject component or system remained available such that no unrecognized increase in risk occurred. The inspectors compared the operability and design criteria in the appropriate sections of the TS and UFSAR to Entergy evaluations to determine
whether the components or systems were operable. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled by Entergy. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations.
b. Findings
No findings were identified.
1R18 Plant Modifications
.1 Temporary Modification to Install Temporary Power to the 24 Volt DC (VDC) System
a. Inspection Scope
The inspectors reviewed temporary modification procedure 3.M.3-36.8, Revisions 1 and 2, "Temporary Power for +/- 24VDC Bus 'A' or 'B'", to determine whether the performance capability of the 24VDC system had been degraded through the modification. The inspectors reviewed Control Room drawings, relevant condition reports, and work orders to ensure the temporary modification did not adversely affect the 24VDC system. The inspectors reviewed the annotated drawings to determine whether they properly reflected the temporary modification. The inspectors also walked 11 Enclosure down the temporary power supply in the upper switchgear room to review the installed modification.
b. Findings
No findings were identified.
.2 Permanent Modifications
a. Inspection Scope
The inspectors evaluated a modification to Pilgrim's four Safety Relief Valves and subsequent Reactor Core Isolation Cooling (RCIC) controller calibration implemented by engineering change package EC5000071989, Rev. 8, "SRV/SSV Setpoint & Tolerance Increase and Replacement." The inspectors verified that the design bases, licensing bases, and performance capability of the affected systems were not degraded by the modification. In addition, the inspectors reviewed modification documents associated with the design change, including the design package and RCIC demonstration test procedure 8.5.5.13, Rev. 0, "RCIC Pump Quarterly Operability Flow Rate and Valve Test with Supplemental Pump/Turbine Performance Testing for Benchmarking EC5000071989 Design Assumptions."
b. Findings
No findings were identified.
1R19 Post-Maintenance Testing
a. Inspection Scope
The inspectors reviewed the post-maintenance tests for the maintenance activities listed below to verify that procedures and test activities ensured system operability and functional capability. The inspectors reviewed the test procedures to verify that the procedures adequately tested the safety functions that may have been affected by the maintenance activity, that the acceptance criteria in the procedure was consistent with the information in the applicable licensing basis and/or design basis documents, and that the procedure had been properly reviewed and approved. The inspectors also reviewed test data to verify that the test results adequately demonstrated restoration of the affected safety functions.
- 'B' Emergency Diesel Generator KW Swings and Troubleshooting
- Main Steam Safety Relief Valve SV-203-3D Replacement
- Motor Replacement and Testing for the Residual Heat Removal 'A' Pump
- Repairs to the Rod Worth Minimizer

1R22 Surveillance Testing
a. Inspection Scope
The inspectors observed performance of surveillance tests and/or reviewed test data of selected risk-significant structures, systems, and components (SSCs) to assess whether test results satisfied TS, the UFSAR, and Entergy's procedure requirements. The inspectors verified that test acceptance criteria were clear, tests demonstrated operational readiness and were consistent with design documentation, test instrumentation had current calibrations and the range and accuracy for the application, tests were performed as written, and applicable test prerequisites were satisfied. Upon test completion, the inspectors considered whether the test results supported that equipment was capable of performing the required safety functions. The inspectors reviewed the following surveillance tests.
- 'B' and 'D' Residual Heat Removal Pump Quarterly In-service Testing (IST)
- Emergency Diesel Generator 'A' Initiation by Core Spray Logic
- Main Steam Containment Isolation Valve (CIV) Operability Test
- Reactor Coolant System (RCS) Leakage Detection Surveillance
- Station Blackout Diesel Generator Surveillance
b. Findings
No findings were identified.
Cornerstone:
1EP6 Drill Evaluation
Emergency Preparedness Drill Observation
a. Inspection Scope
The inspectors evaluated the conduct of an emergency drill on February 29 to identify any weaknesses and deficiencies in the classification and notification of emergency action levels. The inspectors observed emergency response operations in the simulator and emergency operations facility to determine whether the event classification and notifications were performed in accordance with procedures. The inspectors also attended the station drill critique to compare inspector observations with those identified by Entergy staff in order to evaluate Entergy's critique and to verify whether Entergy's staff was properly identifying weaknesses and entering them into the corrective action program.
b. Findings
No findings were identified.
RADIATION SAFETY
Cornerstones: Occupational and Public Radiation Safety
2RS0 1 Radioactive Hazard Assessment and Exposure Controls
a. Inspection Scope
During the period of February 13 - 16, the inspector conducted the following activities to verify that Entergy was evaluating, monitoring, and controlling radiological hazards for work performed in locked high radiation areas (LHRA) and other radiological controlled areas, and that workers were adhering to these controls when working in these areas.
Implementation of these controls was reviewed against the criteria contained in 10 CFR Part 20, Technical Specifications, and Entergy's procedures.
Radiological Hazards Control and Work Coverage
The inspector identified exposure significant work areas. The inspector reviewed radiation survey maps and radiation work permits (RWPs) associated with these areas to determine if the associated controls were acceptable. The inspector attended the pre-job and RWP briefings and interviewed selected workers to determine if the workers were informed of the radiological conditions at the job site, electronic dosimeter alarm set points, and actions to be taken if a dosimeter alarms. Specific work activities observed included a High Pressure Coolant Injection (HPCI) pump surveillance test during full power operations.
The inspector toured the accessible radiological controlled area, including the reactor building, turbine building, and radwaste building, and performed independent surveys of selected areas to confirm the accuracy of survey data and the adequacy of postings.
During this tour, the inspector verified that selected LHRAs were properly secured and posted.
In evaluating the RWPs, the inspector reviewed electronic dosimeter dose/dose rate alarm set points to determine if the set points were consistent with the survey indications and plant policy. The inspector verified that workers were knowledgeable of the actions to be taken when the dosimeter alarms, or malfunctions, for tasks being performed under selected RWPs.
The inspector reviewed Entergy's procedure for measuring personnel exposure using the effective dose equivalent method. The inspector confirmed that the method was approved by the NRC and that the implementi ng procedure appropriately specified the placement of whole body and extremity dosimeters on the worker.

A review of Nuclear Oversight (NO) field observation reports, related Condition Reports (CRs), and an audit report (No.QA-14/15-2011-PNP-1) was conducted to determine if identified problems and negative performance trends were entered into the corrective action program and evaluated for resolution.
Relevant CRs, associated with radiation protection control access, initiated between October 2011 and February 2012, were reviewed and discussed with Entergy staff to determine if the follow up activities were being conducted in an effective and timely manner, commensurate with their safety significance.
High Radiation Area and Very High Radiation Area Controls Procedures for controlling access to High Radiation Areas (HRA) and Very High Radiation Areas (VHRA) were reviewed to determine if the administrative and physical controls were adequate. The inspector also reviewed the physical and procedural controls for securing and removing highly contaminated/activated materials stored in the spent fuel pool. The inspector discussed with radiation protection management the adequacy of current LHRA/VHRA controls, including prerequisite communications and authorizations, and verified that any changes made to relevant procedures did not substantially reduce the effectiveness and level of worker protection. The inspector conducted an inventory of LHRA/VHRA keys to verify accountability.
Radiation Worker Performance and Radiation Protection Technician Performance The inspector observed and questioned radiation workers and radiation protection technicians regarding radiological controls applied to various tasks, including a HPCI test run and various maintenance tasks. The inspector determined that the workers were aware of current RWP requirements, radiological conditions, access controls, and that the skill level was appropriate with respect to the potential radiological hazards and the work being performed.
The inspector attended a Radiation Protection Department daily planning meeting to assess the level of detail provided to workers regarding planned work activities.
The inspector reviewed CRs related to radiation worker and radiation protection technician errors, and personnel contamination event reports to determine if an observable pattern traceable to a similar cause was evident.
Contamination and Radioactive Material Control At the radiological controlled area (RCA) control point, the inspector observed workers surveying and releasing potentially contaminated materials for unrestricted use. The inspector verified that the counting instrumentation was located in a low background area and that the instruments' sensitivity was appropriate for the type of contamination being measured.
The inspector reviewed Entergy's procedures for storing, issuing, and inventorying sealed radioactive sources. The inspector toured plant areas where sealed sources were stored. During this tour, the inspector conducted spot checks of various 15 Enclosure radioactive sealed sources to verify their presence. Through this review, the inspector determined that sources were properly tested for possible leaks, all sources were appropriately accounted for, and that the storage containers were properly secured and labeled.
b. Findings
No findings were identified.
2RS0 2 Occupational ALARA Planning and Controls
a. Inspection Scope
During the period of February 13 - 16, the inspector conducted the following activities to verify that Entergy was properly implementing operational, engineering, and administrative controls to maintain personnel exposure As Low as Reasonably Achievable (ALARA) for tasks performed during 2011 and in performing ongoing activities. Implementation of these controls was reviewed against the criteria contained in 10 CFR Part 20, applicable industry standards, and Entergy's procedures.
Radiological Work Planning
The inspector reviewed pertinent exposure information regarding the spring 2011 refueling outage (RFO), current exposure trends, and ongoing activities to assess ALARA performance. A review of 2011 outage dose was conducted to compare actual exposures with forecasted estimates to determine if differences were properly addressed in Work-In-Progress and Post-Job ALARA reviews.
The inspector evaluated the departmental interfaces between radiation protection, operations, maintenance crafts, and engineering to identify missing ALARA program elements and interface problems. The evaluation was accomplished by attending an ALARA Manager's Meeting for an entry into a steam affected area to troubleshoot a main steam isolation valve (MSIV-203-2B); reviewing the refueling outage post-job ALARA reviews, reviewing the post-job ALARA review for replacing a residual heat removal motor, and reviewing past ALARA Manager's Committee meeting minutes, and NO audit/field observations, and interviewing the site Radiation Protection Manager.
Verification of Dose Estimates
The inspector reviewed the assumptions and basis for the annual (2012) site collective dose, exposure projections and actual exposure data for the 2011 spring outage, and for routine power operations. The inspector evaluated in detail projects whose dose exceeded five person-rem. The inspector reviewed the effectiveness of initial job planning measures and Entergy's efforts in monitoring and controlling dose during job completion by the ALARA Manager's Committee.
The inspector reviewed Entergy's procedures associated with monitoring and re-evaluating dose estimates when the forecasted cumulative exposure for tasks differed from the actual exposure received. The inspector reviewed the dose/dose rate alarm reports, post-job ALARA reviews, and exposure data for selected individuals receiving the highest Total Effective Dose Equivalent (TEDE) for 2011, to confirm that no individual exposure exceeded the regulatory limit or met the performance indicator reporting guideline.
Jobs-In-Progress
The inspector observed a job-in-progress to evaluate the effectiveness of dose and contamination control measures. The job observed was a surveillance test run of a HPCI pump during full power operations. As part of this evaluation, the inspector attended the pre-job and RWP briefing, reviewed the RWP and associated survey maps, and evaluated contamination control measures.
Declared Pregnant Workers
The inspector reviewed the implementing procedure for processing, monitoring, and limiting the exposure of personnel who are Declared Pregnant Workers (DPW). The inspector determined that no DPWs were recently employed who were assigned to perform work within the RCA.
Problem Identification and Resolution The inspector reviewed elements of Entergy's corrective action program related to implementing ALARA program controls, including condition reports, NO field observation reports, audits, and dose/dose rate alarm reports, to determine if problems were being entered at a conservative threshold and resolved in a timely manner.
b. Findings
No findings were identified.
OTHER ACTIVITIES

On February 7, Entergy identified that the DC Solenoid Valve for MSIV 2B was inoperable. Two solenoid valves (AC and DC) maintain the MSIVs open and the loss of one of these solenoid valves does not cause an MSIV to close. Entergy evaluated plant risk and established risk management actions to protect the AC solenoid, its power supply, and applicable system relays. Entergy subsequently repaired the DC solenoid during a thermal backwash activity on February 23, and restored the MSIV 2B DC solenoid to service.
b. Findings
No findings were identified.
.3 Operator Performance During Power Maneuvers to Support Main Condenser Thermal
Backwash
a. Inspection Scope
The inspectors observed operators perform a thermal backwash of the main condenser
on February 23. Specifically, the ins pectors observed a planned downpower to approximately 47 percent reactor power to support the backwash and maintenance on the MSIV 2B DC solenoid valve. The inspectors reviewed procedural guidance for station power changes, the power maneuver plan, and observed the Infrequently Performed Test or Evolution brief. The inspectors observed just-in-time training prior to
the evolution and then subsequently observed control room operator performance during the power maneuvers.
b. Findings
No findings were identified.
.4 Operator Performance During a Downpower to Support a Control Rod Pattern
Adjustment
a. Inspection Scope
The inspectors observed an infrequently perform ed evolution on March 14. Specifically, the inspectors observed a planned downpower to support a control rod pattern adjustment and control rod settle testing.
