This report covered a three-month period of inspection by resident and region-based inspectors. Two findings of very low significance (Green) were identified, one of 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 (
- NUR [[]]
- A. [[]]
NRC-Identified and Self-Revealing Findings Cornerstone: Initiating Events * Green. The inspectors identified a non-cited violation (NCV) of 10 CFR 50.65(a)(4), because Entergy personnel did not adequately assess and manage increased risk associated with planned corrective maintenance. Specifically,
Entergy staff did not include in their maintenance risk assessment the increase in shutdown plant risk for the repacking of
- SP [[-954A, a non-isolable root isolation from the reactor coolant system associated with the sampling system, during fuel reload operations. The inadequate risk assessment and management of the risk associated with this job resulted in a short duration leak in the]]
RCS. The inspectors determined this finding affected the Initiating Event cornerstone and was more than minor because the risk assessment did not consider maintenance activities that could increase the likelihood of initiating events. The inspectors determined this finding was of very low safety significance because
Entergy staff maintained required mitigation capability in accordance with IMC 0609, Appendix G, Attachment 1, Checklist 4. The inspectors determined that this finding had a cross-cutting aspect in the area of Human Performance because personnel did not appropriately plan work activities by incorporating appropriate risk insights, job site conditions, contingencies, and abort criteria
consistent with nuclear safety. (H.3(a)) (Section
- 4OA [[3) * Green. A self-revealing finding of very low safety significance was identified because Entergy personnel did not have adequate procedures appropriate for maintenance associated with air-operated valves. Specifically, existing Entergy maintenance procedures did not ensure that the 33 steam generator (]]
SG) feedwater regulating valve (FRV) positioner feedback arm connecting linkage hardware was properly secured following maintenance. As a result, on May 15, 2009, this linkage became disconnected which led to SG level oscillations that
required a manual reactor trip by control room operators. Entergy personnel repaired the valve positioner feedback arm connecting linkage, identified the
Enclosure main cause during a post-transient review, performed extent of condition inspections on similar valves susceptible to the same linkage deficiency, and completed a root cause analysis within the corrective action program under condition report (CR)-IP3-2009-02368. The inspectors determined the finding is more than minor because the finding is associated with the equipment performance attribute of the Initiating Events cornerstone and affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during
shutdown as well as power operations. Specifically, the inadequate procedures resulted in the failure of a non-safety-related portion of the
- 33 SG [[]]
- FRV and resulted in a manual reactor trip. The inspectors evaluated the significance of the finding using
- IMC [[0609, Attachment 4, and determined this finding did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would be unavailable. Consequently, the finding is of very low safety significance (Green). The inspectors determined that this finding had a cross-cutting aspect in the area of Human Performance because Entergy staff did not ensure that complete, accurate and up-to-date procedures were available to perform appropriate maintenance on air-operated valve positioners associated with the 33]]

DETAILS Summary of Plant Status
Indian Point Unit 3 began the inspection period in a shutdown condition for continuation of refueling outage No. 15 (3R15). The unit achieved initial criticality on April 15, 2009, and reached full power on April 19. Operators manually tripped the Unit 3 reactor May 15 due to a degraded feedwater regulating valve. Operators restored the plant to full power on May 16. Subsequently, problems associated with main boiler feedwater pumps (MBFP) resulted in a
downpower to 75% on May 28 and an automatic reactor trip due to steam generator water level control issues. Following repairs to the
- 31 MBFP , the unit was re-started on May 29 and was stabilized at 55% power to perform repairs to the 32
- MBFP control systems resulted in a subsequent shutdown on May 31 to perform repairs. Subsequently, on June 5, operators returned the plant to 65% power while maintenance staff repaired the 32
- 32 MB [[]]
FP was returned to service and operators restored reactor power to 100%. Unit 3 remained at full power for the remainder of the
inspection period. 1.

ACTIVITIES
4OA1 Performance Indicator Verification Resident Inspector Baseline Inspection (71151 - 2 samples)
a. Inspection Scope The inspectors reviewed the performance indicator data listed below, which is associated with the Barrier Integrity and Mitigating Systems cornerstones, respectively. The inspectors used Nuclear Energy Institute 99-02, "Regulatory Assessment
Performance Indicator Guideline," Rev. 5, and applicable Entergy procedures to verify individual performance indicator accuracy and completeness. The documents reviewed during this inspection are listed in the Attachment. * Reactor Coolant System Specific Activity (April 2008 to March 2009) * Safety System Functional Failure (April 2008 to March 2009)
Enclosure b. Findings No findings of significance were identified.
- 4OA 2 Identification and Resolution of Problems (71152 - 3 samples) .1 Routine Problem Identification and Resolution (
PI&R) Program Review a. Inspection Scope As required by Inspection Procedure 71152, "Identification and Resolution of Problems," and to 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 corrective action program. The review was accomplished by accessing Entergy's computerized database for condition reports, and attending condition report screening meetings.
In accordance with the baseline inspection procedures, the inspectors selected corrective action program items across the Initiating Events, Mitigating Systems, and Barrier Integrity cornerstones for further follow-up and review. The inspectors assessed Entergy personnel's threshold for problem identification, the adequacy of the cause
analysis, extent of condition reviews, operability determinations, and the timeliness of the associated corrective actions. The condition reports reviewed during this inspection are listed in the applicable inspection sections. b. Findings No findings of significance were identified. .2 Public Radiation Safety Cornerstone
a. Inspection Scope The inspectors screened 33 corrective action condition reports initiated between January 2008 and June 2009 and associated with the radiological waste transportation program. b. Findings No findings of significance were identified. .3 Focused Review of Corrective Actions Related to the Installation and Project Management of the New Alert and Notification System (ANS) (71152 - 1 sample)
a. Inspection Scope The inspectors reviewed Entergy personnel=s actions in response to condition reports (CRs) generated as a result of issues associated with the installation and project management of the new alert and notification system (ANS) for the Indian Point Energy Center. The inspectors also reviewed Entergy procedures on project management and
Enclosure external stakeholder communications. In addition, the inspectors interviewed applicable members of Entergy's staff including a lead project manager and licensing staff. The focus of this inspection was to verify that the corrective actions, reviewed during the December 2008 Enforcement Follow-up Inspection (Inspection Procedure 92702,
- ML 090280267), were being completed in a thorough and timely manner. b. Findings No findings of significance were identified. The inspectors reviewed
ANS placed into service for the Indian Point Energy Center in 2008. Entergy staff has taken appropriate corrective actions, or has corrective actions planned to address each issue that was identified. For example, inspectors verified that responsible personnel have taken corrective actions, or have corrective actions planned to revise their project management process, require greater senior management oversight for projects, and develop a new
procedure for interactions with external stakeholders. .4 Semi-Annual Trend Review: Human Performance - Error Prevention Techniques (71152 - 1 sample)
a. Inspection Scope In July 2009, inspectors reviewed Entergy staff's progress in implementing corrective actions identified in 2008 to address Human Performance issues as outlined in Entergy's Human Performance Improvement Plan with a focus on specific efforts since January
2009. The inspectors evaluated staff performance improvement plans and actions using inspection guidance in Inspection Procedure 71152, "Identification and Resolution of Problems." Specifically, the inspectors assessed Entergy's progress in addressing human performance by evaluating whether Entergy's internal milestones were being monitored and consistently met and whether adjustments in approach were made when
necessary. This inspection focused on the actions implemented since January 2009. The inspectors conducted a review of the applicable condition reports (CRs), corrective action assignments (CAs), focused self-assessments, Quality Assurance group assessments, and causal evaluations for human performance events and errors. The
inspectors also reviewed Entergy internal performance indicators related to their performance improvement plan, and reviewed a sample of revised procedures in order to assess the adequacy of the performance plan and effectiveness of corrective actions. b. Findings and Observations No findings of significance were identified.
In late December 2008, NRC inspectors independently reviewed the causal evaluation and corrective actions focused on an emerging trend, identified by Entergy personnel, and associated with human performance errors. Entergy staff and managers identified several events, attributable to human performance errors that occurred at Indian Point
(both units) in 2008, which resulted in personal injury and/or equipment failures. The
Enclosure inspectors determined that Entergy managers recognized this adverse trend in human performance, and developed a Human Performance Program to address the causes of the events, and to assist in the prevention or mitigation of future occurrences. The inspectors noted that the Human Performance Program included actions to understand
the causes of human performance errors, to reduce these human performance errors in the future, and to monitor future performance. The inspectors determined Entergy staff and managers developed station-wide communication tools, training plans, and adjusted the site business plan to address
these common causes of human performance errors. New communication tools developed included Safety and Human Performance Stand Downs and periodic human performance bulletins. The Safety and Human Performance Stand Downs were used to develop a forum to reinforce site human performance expectations and discuss recent human performance error events. Entergy managers also scheduled future stand downs to coincide with major evolutions on site in 2009, such as the Unit 3 refueling outage.
The inspectors noted that Entergy staff developed a Human Performance Simulator and Work Management Academy to provide training on human performance traps, human performance tools, and to improve work planning and execution. The Human Performance Simulator focuses on reinforcing the proper threshold for identifying error traps and the effective use human performance tools to accomplish tasks. Operations
and maintenance departments have completed this training, and it will now be included as annual refresher training for their department personnel. The Work Management Academy was required for all supervisory personnel and reinforced Entergy's work management model and procedures. Entergy staff and managers also developed its Thought Improvement Process (TIP) Initiative to encourage employees to provide
constructive feedback to improve the site's human performance. The inspectors also noted that Entergy staff and managers established commitments to monitor future human performance at Indian Point. In particular, human performance indicators and self-assessment results would be used to monitor the effectiveness of the
current programs and for evaluation of future trends in human performance. The inspectors concluded that Entergy managers took action to address the site's emerging adverse human performance trend. The programs established within Entergy's Human Performance program were determined to be reasonable to address the recent human performance.
During the July 2009 semi-annual trend review, inspectors determined that Entergy staff continued to make progress in implementing their corrective action plans to address human performance issues related to error prevention and to make adjustments to those actions based on the results of self-assessments, performance indicators, and benchmarking. For example, based on observations of supplemental workers during the recent Unit 3 refueling outage, actions were being developed to provide additional
oversight of supplemental workers. The inspectors also noted that, in accordance with previous corrective actions, Entergy staff and managers had: * Continued to use the Human Performance Simulator to train various departments, and to check and adjust development of dynamic learning activities in the simulator;
Enclosure * Implemented a standard schedule for site wide stand downs during outage and non-outage periods; * Revised pre-job briefing procedures to include signature accountability, * Implemented a task/job observation program aligned with the work control process and Most Error Likely Task-focused crew assessments; * Assigned experienced mechanics, technicians, and operators to procedure groups; * Reinforced critical procedure steps through the use of special markings, briefs, and feedback; * Filled key personnel vacancies previously identified as necessary to strengthen the organization's effectiveness in preventing human error; * Improved adherence to online and outage work management milestones; * Improved effectiveness of work package walk downs and feedback; * Established weekly work package quality meetings. Additionally, the inspectors noted that Entergy has developed additional performance indicators to assist in monitoring progress in addressing human errors, and is planning to
conduct annual Human Performance training to first-line supervisors and above. The recent trend in human performance related to error prevention indicated that corrective actions, to date, have not resulted in a decrease in the human error rate trend, primarily due to issues that occurred during the Unit 3 refueling outage.
Notwithstanding, the inspectors concluded that station management has adjusted its actions/focus as a result of its evaluation of additional performance information, especially from the outage. The programs and actions established within Entergy's Human Performance program were determined to be reasonable to address the recent human performance issues related to error prevention.
.5 Focused Review of Corrective Actions for 31 Emergency Diesel Generator Fuel Oil Control Valve Maintenance Issues (71152 - 1 sample) a. Inspection Scope The inspectors reviewed Entergy's corrective actions to address inadequate maintenance associated with the 31 emergency diesel generator (EDG) detailed under condition report
IP3-2008-02508, dated October 9, 2008. The inspectors evaluated the apparent cause evaluation to ensure the identified causes and corrective actions
were adequate and appropriate for the circumstances, as well as commensurate with the safety significance applicable to the highly risk significant EDGs. b. Findings and Observations No findings of significance were identified.
However, the inspectors identified the apparent cause evaluation (ACE) did not address a work control issue. Specifically, the inspectors concluded the evaluation team did not fully consider that Entergy personnel planned and performed this maintenance under the minor maintenance work control process contrary to Entergy work control procedures.
Enclosure The inspectors determined that the Entergy work control procedures, detailed in
WM-105, "Planning," identify that detailed work instructions are required for those work
activities that are risk significant and require entry into limiting conditions for operation. In accordance with these procedures, more detailed work instructions should have been generated to ensure the work activity associated with the 31 EDG was appropriate for the circumstances. In particular, contrary to the above procedures, the minor maintenance work package did not contain adequate instructions regarding the
operation and maintenance of the fuel oil pressure control valve (PCV),
- EDG. The instructions did not provide for details regarding the gasket replacement and its effect on the
- 31 EDG not being able to provide appropriate fuel oil pressure to meet surveillance and operational requirements during the post-maintenance testing, and required a premature shutdown of the
EDG, as well
as accrual of additional out-of-service hours. The inspectors determined that the performance of maintenance on the 31 EDG, using a minor maintenance work package contrary to established work control procedures was a violation. However, because the equipment issue was identified by Entergy personnel
prior to the completion of the overall maintenance window, the inspectors determined that in accordance with
- IMC [[0612, Appendix E (Section 5), the performance issue is considered a "work-in progress" issue that is of minor significance. As a result, this failure to comply with Entergy work control procedures constitutes a violation of minor significance that is not subject to enforcement action in accordance with the]]
NRC's
Enforcement Policy. Entergy personnel entered this issue in the corrective action program (CR-IP3-2009-02958). 4OA3 Event Follow-up (71153 - 4 samples)
.1 Unintended
RCS at >90 ft a. Inspection Scope The inspectors evaluated Entergy staff's response to an unintended RCS leak initiated
when supplemental maintenance workers commenced work to replace the packing in valve
- RCS [[hot leg. Specifically, the inspectors reviewed Entergy staff's response to the event and reviewed the conditions that led to the event to evaluate if additional inspection was required, and to ensure that Entergy personnel properly classified the event. The inspectors verified Entergy's corrective actions were appropriate in response to the event. This issue was initially entered into Entergy's corrective action program as]]
IP3-2009-01550 with a
follow up entry as
Enclosure b. Findings Introduction: The inspectors identified a
CFR 50.65(a)(4) because Entergy personnel did not adequately assess and manage
the risk associated with planned corrective maintenance. Specifically, Entergy personnel did not include the increase in shutdown plant risk in its risk assessment and use appropriate mitigating strategies while repacking SP-954A during fuel reload operations.
Description: On April 1, 2009, Indian Point Unit 3 was in a shutdown condition for refueling outage 3R15. The plant was in Mode 6, "Refueling," with reactor core reload in progress, and the refueling cavity was flooded to approximately 93', as required to support fuel movements. The inspectors noted that maintenance personnel were assigned to perform work order (WO) 51483809, Task 1, "Packing Leak Noted During
RCS Integrity Test, SP-
954A Packing Leak During
- RCS Integrity Test," with a site radiological protection (RP) technician providing radiological support. To replace the valve's packing, the
- WO directed the workers to remove the valve's bonnet and internals. This valve is a root stop isolation valve for a sample system line from the 31 reactor coolant system (
RCS) loop, and is not isolable from the
- RP technician noticed an unexpected amount of water coming from the inside of the valve. The maintenance and
RP technician promptly replaced the valve bonnet in order to stop the leak, which was later estimated at approximately one liter of RCS water. The inspectors determined that
this condition represented an uncontrolled leak in the
- RCS and noted that no individual was contaminated as a result. During the review of this condition, the inspectors noted that the repacking of
SP-954A was originally scheduled to be conducted by Entergy personnel on March 27, 2009,
while the
RCS hot leg, which is approximately at the 62' elevation. Due to work backlogs, this maintenance item was transferred to supplemental personnel for completion on March 29, 2009. However, it
was identified that the work activity required the installation of scaffolding to perform the maintenance, which further delayed the work until April 1, 2009. Since this work item did not have the proper logic ties in the outage schedule to the original, drained-down and defueled condition, the subsequent delays in the actual start of this work activity resulted in the work being performed after the reactor cavity was re-flooded to support fuel reload.
Entergy personnel utilize procedure
- 10 CFR 50.65, "Requirements for monitoring the effectiveness of maintenance at nuclear power plants" are met during plant shutdown conditions.
IP-SMM-OU-104 requires the Outage Risk Assessment Team (ORAT) to review the outage schedule prior to shutdown to assess the sequencing of events and document any errors
within the schedule. Additionally, the
- OR [[]]
AT is required to document their review and all
Enclosure resolutions to errors that had been identified within the schedule in a condition report prior to the commencement of the outage. In the 3R15 Refueling Outage Schedule Risk Assessment Report, the
- OR [[]]
AT identifies that a drain-down to 61' 8" was to occur on March 27, 2009, to support work activities associated with the 31 reactor coolant pump
(RCP), and did not describe work to be performed on
ORAT review of the outage schedule did not identify that the proper logic ties, which would have prevented the valve repack work from drifting out of the appropriate drain down window, were not in place for WO 51483809.
The inspectors reviewed Entergy staff's root cause analysis (RCA) of the event, which detailed two root causes and three contributing causes associated. Specifically, the root causes were determined to be: (1) Failure to Comply With (Tag out) Procedural Requirements, and (2) Inadequate Tag Out to Ensure Worker Protection. The contributing causes were determined to be: (1) Inadequate Commitment to Outage Preparation, (2) Missed Opportunity in Scheduling Work, and (3) Missed Opportunity to Identify Inappropriate Plant Conditions for Scope of Work During Pre-job Briefs.
Consistent with these contributing causes, the inspectors determined that Entergy personnel did not identify their failure to properly assess and manage the risk associated with the SP-954A valve work prior to outage 3R15, and during opportunities within the outage process that occurred following the originally-scheduled start date of March 27th, e.g., (1) work backlog that transferred the activity to supplemental personnel, (2) the
delay to build scaffolding, and (3) the actual day the work started. Analysis: The inspectors determined there was a performance deficiency because Entergy staff did not completely and accurately assess and manage the increase in plant risk resulting from planned maintenance activities.
The inspectors determined that this finding affected the Initiating Event cornerstone and was more than minor because Entergy staff's risk assessment did not consider maintenance activities that could increase the likelihood of initiating events. The inspectors determined the significance of this finding using IMC 0609, Appendix G,
"Shutdown Operations Significance Determination Process." The inspectors determined this finding was of very low safety significance (Green) because Entergy personnel maintained required mitigation capability in accordance with IMC 0609 Appendix G, Attachment 1, Checklist 4.
The inspectors determined that this finding had a cross-cutting aspect in the area of Human Performance, because Entergy personnel did not appropriately plan work activities by incorporating appropriate risk insights, job site conditions, contingencies, and abort criteria consistent with nuclear safety. (H.3(a)) Enforcement: 10 CFR 50.65(a)(4), requires, in part, that licensees assess and manage the increase in risk that may result from proposed maintenance activities. Contrary to
the above, prior to and during the 3R15 refueling outage, Entergy personnel did not adequately assess and manage the increase in risk associated with the packing replacement on
SP-954A work had on nuclear safety, i.e., a possible unmonitored/uncontrolled leak
in the RCS, and take appropriate actions to control the maintenance. Because this
Enclosure violation is of very low safety significance and has been entered into the Entergy's corrective action program as

.2 Manual Reactor Trip on May 15, 2009 (3FO9A)
a. Inspection Scope The inspectors evaluated the response of control room personnel following the manual reactor trip that was initiated due to steam generator water levels that approached automatic reactor trip setpoints. The inspectors reviewed plant computer data, which included the sequence of events report and 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 post-trip review group (PTRG) correctly identified the cause(s) of the trip to ensure appropriate corrective actions were implemented prior to restart. This event and the
- CR [[]]

information for applicability: Review of Operating Experience Smart Sample: OpESS
- FY [[2009-02, "A Negative Trend and Recurring Events Involving Feedwater Systems." b. Findings Introduction: The inspectors identified a self-revealing finding of very low safety significance (Green) because Entergy personnel did not have adequate procedures for the circumstances for maintenance associated with air-operated valves. Specifically, existing Entergy maintenance procedures did not ensure that the 33 steam generator (]]
SG) feedwater regulating valve (FRV) positioner feedback arm connecting linkage
hardware were properly secured following maintenance. As a result, on May 15, 2009, this linkage became disconnected which led to
- SG level oscillations that required a manual reactor trip by control room operators. Description: On May 15, 2009, Unit 3 control room operators responded to
SG water level, operators manually tripped the reactor prior to automatic reactor protection setpoints being reached. Subsequently, Entergy personnel identified that feedback linkage (threaded rod between swivel-joints) between the valve actuator and the valve positioner for FCV-437 had disconnected, and that a locking nut on the threaded rod portion had backed off, which was an unexpected condition. A post-transient review team was
initiated, as well as a root cause evaluation, to determine the cause of the event. In addition, Entergy personnel performed an initial extent-of-condition review to determine the condition of other valve positioners that may present similar operability or functionality concerns. The inspectors noted that Entergy personnel completed the post-transient review, performed repairs on the
FRV, due to
Enclosure concerns regarding the conduct of maintenance on both valves during the recent refueling outage that ended in April 2009. The inspectors reviewed the root cause analysis (RCA), which was conducted under
condition report
- IP [[3-2009-02368. The inspectors noted that Entergy personnel had determined the cause of the event to be inadequate procedure directions and written instructions, with one of the contributing causes attributed to ineffective use of human performance tools. Specifically, the governing maintenance procedure for the]]
VLV-416-AOV, did not have appropriate guidance for the proper installation and
tightening of locknuts for the feedback linkage. Additionally, the
FRV diagnostic testing procedure, 0-VLV-404-AOV, which followed the performance of the overhaul and maintenance of the valve during the most-recent refueling outage, required a specific "inspection" be performed under the calibration/post-maintenance section of this procedure. In Attachment 5, the technician is required to inspect the feedback linkage to ensure jam nuts on the threaded rod are tight. The RCA detailed that this "inspection" provided an opportunity for confusion because it did not explicitly
define the inspection attribute of "tight." The RCA also detailed a missed opportunity in that the technician did not observe that the upper jam nut on the threaded rod of the feedback linkage was missing. While the inspectors determined that this lockwasher was most likely not installed during
original installation during the preceding refueling outage in 2007, the inspectors concluded that it should have been identified during the most recent 2009 outage, because the remaining FRVs on both units have lockwashers installed on both ends of the threaded rods. Moreover, operating experience located within the governing procedures, which are also required to be discussed during pre-job briefs, identify the
different failure mechanisms of air-operated valves in high vibration environments. Some of these failures address the proper tightening and installation of jam nuts or appropriate locking mechanisms to prevent similar occurrences, which in turn, should have sensitized the technicians to these issues to ensure jam nuts encountered during these maintenance opportunities were appropriately tightened.
The inspectors also noted that the maintenance and diagnostic procedures were reviewed under the Procedure Upgrade Project (PUP). This project was instituted by Entergy personnel in response to identified deficiencies in procedures that manifested into inspection findings in previous assessment periods, and a classification of a
substantive cross-cutting issue that warranted Entergy's establishment of the PUP to improve the quality of procedures at both Units No. 2 and 3. Analysis: The inspectors determined there was a performance deficiency because Entergy did not have adequate maintenance procedures to ensure for positive locking of connecting hardware for air-operated valve positioner feedback linkages. The inspectors concluded the finding is more than minor because the finding was associated
with the equipment performance attribute of the Initiating Events cornerstone and affected the cornerstone objective to limit the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, the inadequate procedures resulted in the failure of a non-safety-related portion of FCV-437, the 33 steam generator main feedwater regulating
valve, and resulted in a manual reactor trip due to steam generator water levels that
Enclosure approached automatic reactor trip protection actuation setpoints. The inspectors evaluated the finding using IMC 0609, Attachment 4, "Initial Screening and Characterization of Findings," and determined the finding did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would
not be available. Consequently, the finding is of very low safety significance (Green). The inspectors determined that this finding had a cross-cutting aspect in the area of Human Performance because Entergy personnel did not ensure that complete, accurate and up-to-date procedures were available to perform appropriate maintenance on air-
operated valve positioners associated with the
- 33 SG [[]]
FRV. (H.2(c)). Enforcement: Enforcement action does not apply because the performance deficiency was related to non-safety related equipment and procedures and did not involve a violation of regulatory requirements. Because this finding does not involve a violation of regulatory requirements and has very low safety significance, this issue is being treated
as a

.3 Automatic Reactor Trip on May 28, 2009 (3FO9B) a. Inspection Scope
The inspectors evaluated the response of control room personnel following the automatic reactor trip that occurred following the down power to 65% in response to increasing vibrations on the 32 main boiler feed pump on May 25, 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 post-trip review group (PTRG) correctly identified the cause(s) of the trip to facilitate corrective actions prior to restart. This event and the
CR IP3-2009-02494. Corrective actions included repair to both the 31 and 32 main boiler feed pumps as well
as a Root Cause Analysis (RCA) to determine the cause(s) of the feed pump failures, due July 9, 2009. b. Findings No findings of significance were identified. .4 Pressurizer Pressure Low Pressure and Instrument Failure Condition on June 10, 2009 a. Inspection Scope The inspectors evaluated the response of control room personnel following the receipt of
a low pressurizer pressure alarm, along with minor turbine power and load oscillations that were observed on June 10, 2009. The inspectors reviewed plant computer data, evaluated plant parameter traces, discussed the condition with plant personnel, and verified that plant equipment responded as expected. The inspectors reviewed 3-AOP-INST-1, "Instrument/Controller Failures," Rev. 5, to verify that required actions were
Enclosure completed. The inspectors also reviewed the details of this condition as documented in the corrective action program under condition report
IP3-2009-02680. b. Findings No findings of significance were identified. 4OA5 Other Activities 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. 4OA6 Meetings, including Exit Exit Meeting Summary On July 22, 2009, the inspectors presented the inspection results to Mr. Joseph Pollock and other Entergy staff members, who acknowledged the inspection results. While some proprietary items were reviewed and returned during the inspection, no proprietary
information is presented in this report.
