SUMMARY OF FINDINGS
IR,05000286/2009-002; 01/01/2009 - 03/31/2009; Indian Point Nuclear Generating Unit 3;
Radiological Access Control.
This report covered a three-month period of inspection by resident and region-based inspectors.
One finding of very low significance (Green) was identified, which was also determined to be 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." The cross-cutting aspect for each finding was determined using IMC 0305,
"Operating Reactor Assessment Program." Findings for which the significance determination process (SDP) does not apply may be Green, or be assigned a severity level after NRC management review. The NRC's program for overseeing 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: Occupational Radiation- Safety
- Green.
The inspectors identified a Green non-cited violation of Technical Specification 5.4.1 .a, "Procedures," because Entergy personnel did not generate condition reports or investigation paperwork for multiple high dose-rate alarms as required by station procedures. Specifically, personnel did not generate the required condition reports and adequately document the investigations for 21 instances of unplanned or un-briefed electronic dosimeter alarms that occurred between January 2009 and March 2009. The performance deficiency resulted in workers receiving unanticipated dose rate alarms with no formally-documented investigation prior to returning to work in a Radiologically Controlled Area. Entergy entered the finding, into the corrective action program as condition report CR-IP3-2009-01253 and 01318.
The finding is more than minor because it is associated with the Occupational Radiation Safety cornerstone attribute of programs and process, and adversely affected the objective to ensure adequate protection of worker health and safety from exposure to radiation. Moreover, the inspectors identified a programmatic deficiency to rhlaintain and implement programs to keep exposures as low as reasonably achievable, because multiple examples were identified regarding the failure to satisfy station radiation protection procedures. Using the Occupational Radiation Safety Significance Determination Process, the inspectors determined that the finding was of very low safety significance (Green) because it did not involve: (1) as low as is reasonably achievable planning and controls, (2) an overexposure of an individual, (3) a substantial potential' for overexposure, or (4) an impaired ability to assess dose.
\
The inspectors determined that the finding'had a cross-cutting aspect related to procedural adherence in the Work Practices component of the Human Performance area. Specifically, Entergy employees did not follow procedures to generate condition reports and document investigations when high dose-rate alarms were received by workers. H.4(b) (Section 20S1)
Licensee-Identified Violations
None.

1R08 In-service Inspection
a. Inspection Scope
Activities inspected during the Unit 3 refuel outage 15 (3R15) included observations of ultrasonic testing (UT) calibration or in-progress component testing using manual and computer based UT techniques. Manual UT observations included the main steam 6" diameter, loop 32, pipe welds 22 and 23 shown on drawing 2201, Rev 6, and review of the UT data sheets for residual heat removal (RHR) pipe welds W13 and W16. The sample of visual inspection (VT) included the areas of the containment inner boundary at the containment liner and containment penetrations. The task work orders and test data for several ultrasonic and visually identified indications were reviewed and confirmed to be evaluated by Entergy personnel as part of the in-service inspection process.
The inspectors observed the video-visual examination results for a sample of the reactor pressure vessel (RPV) upper head-to-control rod drive mechanism (CRDM) penetrations per the EPRI guidelines. This inspection included the sequence of Entergy's evaluation of the as-found conditions, conducted in accordance with procedure 3-PT-R203, Rev. 3, which used a robot crawler to position a camera to view the circumference of each CRDM for boric acid leakage. This inspection also included a comparison of the 2009 visual observations with those of the previous (2007) outage which included CRDMs 17, 24, 41, 53, 60, and 76.
%
The inspectors reviewed a sample of computer-based, eddy current (ET) and ultrasonic testing (UT) records and results of the upper RPV-head-to-CRDM penetrations and weld examinations as conducted from the underside of the RPV head.
In the area of boric acid corrosion control activities, the inspectors confirmed the extent of boric acid walkdowns during plant operation and the plant shutdown process, and verified that identified problem areas were documented in condition reports for evaluation and resolution. In particular, the inspectors reviewed visual records of the as-found and as-left conditions of a reactor vessel head mechanical penetration, Conoseal
- 3, which had experienced some leakage and was identified by Entergy personnel at shutdown. The inspectors confirmed the Conoseal leakage to be from a mechanical joint and not pressure boundary leakage that Was repaired during this refueling outage.
Additionally, the inspectors evaluated the as-left condition on the RPV head in that area and other potentially affected areas. The condition of the upper threads on vessel stud
- 29 and the status of eight other studs were visually inspected to confirm that no significant degradation was present.
The inspectors noted that steam generator (SG) tube inspection results from the 2007 (3R14) outage provided the basis for not performing eddy current testing (ECT) of SG tubes during the 3R15 outage. The inspectors reviewed the SG tube assessment (Report IP-RPT-06-00186) for 3R14 and the documented review (Report IP-RPT-07-00031) of the acceptability of SG operation for two cycles until 3R17. It was noted that the operating conditions between 3R15 and 3R16 would be assessed to confirm that those conditions were consistent With the IP-RPT-07-00031 report prior to the start of RFO 3R16.
The inspectors reviewed computer-based ECT and UT records and examination results of the four hot leg and four cold leg primary piping-to-reactor vessel nozzles consistent with the dissimilar metal weld program under MRP-139. These welds were examined under water from the inside of the reactor pressure vessel (RPV). The answers to the applicable TI 2515/172 (temporary inspection) procedure are included in Section 40A5 of this report. Additionally, the inspectors reviewed a sample of the computer-based ECT and UT records-and examination results of the bottom-mounted RPV penetrations that were accessed from inside the RPV.
The inspectors reviewed the video record of the visual examinations of the three 6" safety and one 4" pressure relief pressurizer upper cast head inner radius to nozzle surfaces to verify the adequacy of the examination technique and to confirm the status of the inner radius and related areas. The accessible areas around the 4" spray nozzle were also viewed although the inner radius of the spray nozzle was not accessible. No items of degradation were observed in any of the visually accessible areas.
The inspectors noted that the surge.:nozzle-to-pipe dissimilar metal, stainless steel weld, located at the bottom of the pressurizer was ultrasonically examined after appropriate preparation of the exterior surface by grinding flush. The inspectors examined the*
grinding mockup, the as-ground condition, the engineering analysis including thickness calculation, and the UT results.

b. Findinqs
Introduction:
The inspectors identified a Green non-cited violation of Technical Specification 5.4.1.a, "Procedures," because Entergy personnel did not generate condition reports or investigation paperwork for multiple high dose-rate alarms as required by station procedures. Specifically, personnel did not generate the required condition reports and adequately document the investigations for 21 instances of unplanned or un-briefed electronic dosimeter alarms that occurred between January 2009 and March 2009.
Description:
During the period January 2009 through March 2009, 21 instances of electronic dosimeter dose rate alarms were recorded by the access control system.
During this period, Entergy personnel inconsistently utilized an informal process of reviewing the alarms without a full investigation or approval process. Moreover, in three of the 21 instances, -the inspectors identified that no investigation or follow-up' had occurred. In some cases, the occurrences were over two months old, which the inspectors noted would have made.resultant investigations more challenging to perform.
In other cases, the alarms were not identified until the worker attempted to re-enter the radiologically controlled area (RCA) and the access control system required manual override to "un-lock" the occurrence to allow entry into the RCA. The inspectors noted that the controlling Entergy procedure for this activity, EN-RP-203, "Dose Assessment,"
specifies that for a dose-rate alarm that is unanticipated or un-briefed, several actions are required, one of which is to initiate a condition report, another is to document the investigation using an attachment in the procedure. Contrary to EN-RP-203, for these 21 instances, no condition reports or attachments were generated with a detailed investigation prior to the workers re-entering the radiologically controlled area. The highest exposure received by these workers during their entry, as indicated by their electronic dosimeter and logged by the access control system, was 33 mRem, while most dosimeters indicated less than 1 mRem for the entry.
Analysis:
The inspectors determined that the failure to generate a condition report, as well as the failure to adequately investigate 21 unplanned or un-briefed electronic dosimeter alarms prior to re-entry into the RCAj as.required by station procedure was a performance deficiency. This performance deficiency was within Enter'gy personnel's ability to foresee and correct, and should have been prevented. This issue was not subject to traditional enforcement, in that it did not have actual safety consequence, it was not an issue that had the potential to impact NRC's ability to perform its regulatory function, and there were no willful aspects.
The finding is more than minor because it is associated with the Occupational Radiation Safety cornerstone attribute of programs and process, and adversely affected its objective to ensure adequate protection of worker health and safety from exposure to radiation. Moreover, the inspectors identified a programmatic deficiency to maintain and implement programs to keep exposures as low as reasonably achievable, because multiple examples were identified regarding the failure to satisfy station, radiation protection procedures. Specifically, in 21 cases, Entergy did not fully evaluate dose rate alarms received by workers in radiologically controlled areas of the plant. Using the Occupational Radiation Safety Significance Determination Process, the inspectors determined that the finding was of very low safety significance (Green) because it did not involve:
- (1) as low as is reasonably'achievable planning and controls,
- (2) an overexposure,
- (3) a substantial potential for overexposure, or
- (4) an impaired ability to assess dose.
The inspectors determined that the finding had a cross-cutting aspect related to procedural adherence in the Work Practices component of the Human Performance area. Specifically, Entergy employees did not follow procedures to generate condition reports and document investigations when-high-dose rate alarms were received by workers. (H.4 (b))
Enforcement.
Technical Specification 5.4.1.a, "Procedures," requires that Entergy establish, implement, and maintain procedures specified in Regulatory Guide (RG) 1.33, Revision 2, Appendix A., Section 7.e, radiation protection procedures for personnel monitoring. Entergy procedure EN-RP-203, Revision 2, Section 5.11, requires that a condition report be written for each unplanned or un-briefed electronic. dosimeter dose-rate alarm. Contrary to the above, the inspectors identified through a review of electronic dosimeter log information from January 2009 through-March 2009, 21 instances of unanticipated or un-briefed electronic dosimeter dose-rate alarms when the procedure was not implemented and condition reports were not generated. Because this finding was of very low safety significance and it was entered into the corrective action program as CR-IP3-2009-001253 and CR-IP3-2009-001318, this violation is being treated as an NCV, consistent with the NRC Enforcement Policy.

a. Inspection Scope
During March 23 - 27, 2009, the inspectors conducted the following activities to verify that Entergy personnel were properly maintaining individual and collective radiation exposures as low as is reasonably achievable (ALARA). Implementation of the ALARA program was reviewed against the criteria contained in 10 CFR 20, applicable industry standards, and Entergy's procedures. This inspection activity represents completion of twelve
- (12) samples relative to this inspection area.
Inspection Planning
- (1) The inspectors reviewed pertinent information regarding cumulative exposure history, current exposure trends, and on-going activities to assess current performance and outage exposure challenges. The inspectors determined the site's 3-year rolling collective average exposure.
- (2) The inspectors reviewed Unit 3 outage work-related activities that occurred during the inspection period, the associated ALARA plans, RWPs, ALARA Committee Reviews, exposure estimates, actual exposures and post job reviews.
Work reviewed included: refuel floor split pin and reactor head inspections, refuel floor lower internals removal and installation, refuel floor and fuel support building fuel transport equipment repairs requiring an underwater diver, reactor coolant pump (RCP) work, which included RCP #31 impeller replacement, containment valve work including pressurizer safety valves, and various containment and primary auxiliary building activities.
- (3) The inspectors reviewed implementing procedures associated with maintaining occupational exposures ALARA. This included a review of the processes used to estimate and track work activity exposures.
Radiological Work Planning
- (4) With respect to the work activities listed above, the inspectors reviewed dose summary reports, related post-job ALARA reviews, related RWPs, exposure estimates and actual exposures, and ALARA Committee meeting paperwork.
This review was also performed to verify that dose was appropriately managed and evaluated by station management.
- (5) ALARA work activity evaluations, exposure estimates, and exposure mitigating requirements were reviewed for work packages previously mentioned, to verify whether Entergy had established procedures, as well as engineering and work controls, based on sound radiation protection principles.
- (6) The inspectors compared the results achieved with the intended dose that was established in the planning of the work. The inspectors determined the reasons for-inconsistencies betweenithe intended and actual work activity doses and station management awareness and involvement.
- (7) The inspectors evaluated for adequacy, the interfaces between operations, radiation protection, maintenance, maintenance planning and others for interface problems or missing program elements.
Verification of Dose Estimates and Exposure Tracking Systems
- (8) Methods for adjusting exposure estimates, or re-planning work, when unexpected changes in scope or emergent work is encountered, were reviewed by the inspectors for adequacy.
Job Site Inspections and ALARA Controls
- (9) The inspectors reviewed work activities that present the highest radiological risk to workers. The inspectors evaluated Entergy personnel's use of engineering controls to achieve dose reductions and to verify that procedures and controls are consistent with ALARA reviews. Associated ALARA Plans and RWPs were reviewed to .determine if appropriate exposure and contamination controls were being employed.
Radiation Worker Performance
- (10) Through observations and interviews by the inspectors, workers and technicians were found to be knowledgeable of the work area radiological conditions and low dose waiting areas.
Declared Pregnant Workers
- (11) The inspectors reviewed information associated with declared pregnant workers during the assessment period and whether appropriate monitoring and controls were being utilized to ensure compliance with 10CFR20.
Problem Identification and Resolution (12)-.

40A3 Event Follow-up Loss of 480 Volt Emergency Safetyýý Bus 6A During Surveillance Testing on January 2, 2009
a. Inspection Scope
The inspectors evaluated the response of control room personnel following the unexpected loss of 480 Volt safeguards bus 6A that occurred during the performance of a degraded grid/undervoltage relay surveillance test on January 2, 2009. The inspectors reviewed plant computer data, evaluated plant parameter traces, and discussed the event with plant personnel, to verify that plant equipment responded as expected, and to ensure that operating procedures were appropriately implemented. The inspectors verified that Entergy's short term corrective actions were appropriate in response to the event. This event was entered into Entergy's corrective action program as CR IP3-2009-00011.
b. Findings and Observations
No findings of significance were identified.
The inspectors noted, however, that corrective actions for the current event were tracked in an on-going root cause evaluation for a similar event that occurred on October 9, 2008. In addition, the inspectors noted a failure analysis was planned for applicable equipment and components, and extensive troubleshooting was planned for'the current
3R15 outage period.
40A5. Other Activities
.1 Continued Groundwater Sampling Effort to Monitor Tritium (Deviation Memorandum
Inspection)a. Inspection Scooe During the week of March 23-27, 2009, the inspectors met with Entergy representatives to review the results of recent groundwater samples, as well as those taken and analyzed in 2008. The review was conducted against criteria contained in 10CFR20, 10CFR50, and applicable industry standards.
The review of the data included a comparison of Entergy's data with split samples taken by the NRC of monitoring wells MW-66 and MW-67, as well as the LaFarge sample point. In all, 47 samples were analyzed and compared from January 2008 through January 2009. Isotopic analyseswere performed and compared at each of the sample points for: Tritium, Strontium 90, Nickel 63, and gamma emitters such as Cobalt-60 and Cesium-1 37. Results of.the NRC samples can be found in ADAMS accession numbers:
ML081420676, ML082690244, ML082690202, ML082690237, ML082730830, ML082730810, ML090400523, ML090400516, ML090400502, ML090923932, ML090920949.
Entergy's evaluation of recent groundwater results are documented in condition reports:
CR-IP2-2009-00883, CR-IP2-2009-01 110, CR-IP2-2009-01 111, CR-IP2-2009-01113, and CR-IP2-2009-01114.
b. Findings
No findings of significance were identified.
- The inspectors concluded that overall, there was agreement between Entergy personnel's results and those independently analyzed by the NRC, and that actions taken by Entergy have been appropriate. The inspectors also noted that conservative estimates indicate that the samples represent a very small fraction of the permissible public dose limits and are negligible with respect to natural background radiation levels.
.2 Inspection Results for TI 2515/172, Reactor Coolant System (RCS) Dissimilar Metal Butt
Welds
a. Inspection Scope
The NRCs Temporary Instruction (TI) 2515/172, provides for confirmation that owners of pressurized-water reactors (PWRs) have implemented the industry guidelines of the Materials Reliability Program (MRP)-139 regarding nondestructive examination and evaluation of certain dissimilar metal (DM) welds in reactor coolant systems containing Alloy 600/82/182. The TI requires documentation of specific questions in an inspection report, and those questions and responses applicable to Indian Point are included below.
In summary, the Indian Point Units 2 and 3 have MRP-139 applicable Alloy 600/82/182 RCS welds in only the hot (HL) and cold leg (CL) pipe-to-reactor pressure vessel (RPV)nozzle connections. These were examined from the inside diameter (ID) surface volumetrically by ultrasonic testing (UT), and on the ID surface by eddy current testing (ECT) at Unit 2 in the 2006 refueling outage, and on Unit 3 from the outside surface visually during the 2007 refueling outage.
For Unit 3 during 3R1 5 in Spring 2009, eight alloy 82/182 welds were examined from the nozzle inner diameter by ECT for the weld surface and UT for the weld volume with ASME'Section XI examination coverage confirmed. The safe end-to-pipe or cast elbow stainless steel welds were also examined by ECT and UT methods. The inspector evaluated the UT and ET techniques, which included the data analysis process and qualifications of both the NDE procedures and the NDE examiners. No significant indications were found on these welds. One very small indication in the weld cladding of CL 34 was identified but found to be acceptable for continued service.
a. For MRP-139 baseline inspections of IP Unit 3 in 2009:
Qal.
Have the baseline inspections been performed or are they scheduled to be performed in accordance with MRP-1 39 guidance?
A.
Yes. The four HL and CL Unit 3 welds were scheduled for UT and ECT examinations and performed during the Spring 2009 3R15 refueling outage.
Qa2.
Is the licensee planning to take any deviations from the MRP-1 39 baseline inspection requirements? If so, what deviations are planned and what is the general basis for the deviation? If inspectors determine that a licensee is planning to deviate from any MRP-139 baseline inspection requirements, NRR should 'be informed by email as soon as
.possible.
A.
No deviations are planned for Unit 3 as the 3R15 ECT and UT examinations complete the MRP-required examination scope.
b. For each examination inspected at IP Unit 3 in 2009 was the activity:
Qbi.
Performed in accordance with the examination guidelines in MRP-139 Section 5.1 for unmitigated welds or mechanical stress improved welds and consistent with NRC staff relief request authorization for weld overlaid welds?
A.
For Unit 3, neither mechanical stress relief nor weld overlays were performed. The four HL and CL Unit 3 weld UT and ECT examinations were performed from the nozzle inside diameter at the DM weld location. Also, the outside surfaces of these welds were visually examined in 2007.
Qb2.
Performed by qualified personnel? (Briefly describe the personnel training/qualification process used by the licensee for this activity.)
A.
The UT was performed with a qualified procedure and by qualified individuals. The eddy current examinations were done in accordance with procedure WDI-STD-146, Rev 9, with review of the qualifications of the ECT individuals as part of the pre-job preparations.
Qb3.
Performed such that deficiencies were identified, dispositioned, and resolved?
A.
One minor indication in the weld internal surface clad material was identified on the 34 CL. This UT-identified condition was reviewed and resolved by the Level Ill data reviewer. The condition was not surface interfacing and was not an eddy current indication.
b. Findings
No findings, of significance were identified
.3 Quarterly Resident Inspector Observations of Security Personnel and Activities
a. Inspection Scope
During the inspection period, the inspectors conducted observations of security force personnel and activities to ensure that these activities were consistent with Entergy security procedures and applicable regulatory requirements. Although these observations did not constitute additional inspection samples, the inspections were considered an integral part of the normal, resident inspector plant status reviews during implementation of the baseline inspection program.
b. Findings
No findings of significance were identified.
