==Dear Mr. Perito:==
- NRC INTEGRATED INSPECTION REPORT NUMBER 05000458/2011002
The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC) Region IV staff will conduct a triennial heat sink inspection at your facility. The inspection will be comprised of one reactor inspector from the NRC Region IV office. The inspection will be conducted in accordance with Inspection Procedure 71111.07T, "Heat Sink Performance." The schedule for the inspection is as follows: onsite inspection: March 14-18, 2011


==Dear Mr. Olson:==
Experience has shown that this inspection is resource intensive both for the NRC inspectors and your staff. In order to minimize the impact to your onsite resources and to ensure a productive inspection, we have enclosed a request for documents needed for this inspection. Please note that the documents are requested to be provided by March 4, 2011. We request, that during the onsite inspection week, you ensure that copies of analyses, evaluations, or documentation regarding the implementation and maintenance of your heat exchanger program are available. Of specific interest are those documents that establish that your heat exchanger program satisfies NRC regulatory requirements and conforms to applicable NRC guidance. Also, appropriate personnel knowledgeable of safety-related heat exchangers should be available to support the inspector at the site during the inspection.
On March 31, 2011, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your River Bend Station. The enclosed integrated inspection report documents the inspecti on findings, which were discussed on April 7, 2011, with you and other members of your staff.


The inspections examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations and with the conditions of your license. The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
We have discussed the schedule for this inspection activity with your staff and understand that our regulatory contact for this inspection will be Ms. Kristi Huffstatler of your licensing organization. If there are any questions about this inspection or the material requested, please contact the lead inspector, Ronald A. Kopriva, at 817-860-8104 or by email, ron.kopriva@nrc.gov . In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).


Based on the results of this inspection, the NRC has determined that one Severity Level IV violation of NRC requirements occurred. The NRC has also identified seven issues that were evaluated under the risk significance determination process as having very low safety significance (Green). The NRC has determined that five of these findings have violations associated with these issues. However, because these violations are of very low safety significance and because they were entered into your corrective action program, the NRC is treating these violations as noncited violations, consistent with Section 2.3.2 of the NRC Enforcement Policy.

=SUMMARY OF FINDINGS=
IR 05000458/2011002; 01/01/2011
 
- 03/31/2011; River Bend Station; Integrated Resident and Regional Report; Equipment Alignments; Refueling and Other Outage Activities
; Emergency Action Level and Emergency Plan Changes; Radiological Hazard Assessment and Exposure Controls  The report covered a 3
-month period of inspection by resident inspectors and announced baseline inspection s by region-based inspector s. Six Green noncited violations and two Green finding s of significance were identified. The significance of most findings is indicated by their color (Green, White, Yellow, or Red) using Inspection Manual Chapter 0609, "Significance Determination Process."  The cross-cutting aspect is determined using Inspection Manual Chapter 0310, "Components Within the Cross Cutting Areas."  Findings for which the significance determination process does not apply may be Green or be assigned a severity level after NRC management review.
 
The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG
-1649, "Reactor Oversight Process," Revision 4, dated December 2006.
 
===A. NRC-Identified Findings and Self-Revealing Findings===
 
===Cornerstone: Initiating Events===
: '''Green.'''
The inspectors reviewed a self-revealing finding involving failure to take adequate corrective actions on a degraded feedwater flow controller push-button, causing a recirculation flow control valve runback, reactor vessel level transient, and a resulting reactor power transient.
 
On September 24, 2008, operations documented a deficiency in the function of the push-button, however station maintenance personnel failed to adequately address the identified deficiency.
 
The push button was subsequently repaired and this issue was entered into the licensee's corrective action program as Condition Report CR-RBS-2011-00300.
 
The finding was more than minor because it was associated with the equipment performance attribute of the Initiating Events Cornerstone, and it affected the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The inspectors evaluated this finding using Phase 1 of Inspection Manual Chapter 0609, Appendix A, "Significance Determination of Reactor Inspection Findings for At-Power Situations," and determined it to be of very low safety significance (Green) because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available. The inspectors determined that the apparent cause of the performance deficiency was the failure to thoroughly evaluate the cause of the defective push-button's stickiness. Consequently, this finding has a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee failed to adequately review the results of the work order to ensure that the cause and extent of condition of the defective push-button was resolved in a timely manner [P.1(c)] (Section 1R20).
 
===Cornerstone: Mitigating Systems===
: '''Green.'''
The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Action," for failure to promptly identify and correct adverse service water chemistry conditions to resolve repetitive service water pressure control valves diaphragm failures that affected operability of the control building chillers.
 
Specifically, station personnel failed to address excessive internal corrosion in the pressure control valves, which resulted in loss of service water pressure control to the control building chillers. As immediate corrective action, the licensee replaced the damaged pressure control valve and is currently evaluating methods to preclude corrosion around the diaphragm.
 
The licensee placed this issue into their corrective action program as Condition Report CR-RBS-2011-02126. The finding was more than minor because it was associated with the equipment performance attribute of the reactor safety Mitigating Systems (MS) Cornerstone, and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.
 
Using Inspection Manual Chapter 0609, "Significance Determination Process," Phase 1 Worksheet, the finding was determined to be of very low safety significance (Green), because it did not result in a loss of system safety function.
 
The inspectors determined that the apparent cause of the performance deficiency was the repetitive failure of 1SWP-PVY32 diaphragm from rust barnacles that formed on the valve internal steel parts during low flow conditions. The apparent cause of the performance deficiency was the station's failure to thoroughly evaluate the cause of the corrosion build up mechanism because the station treated diaphragm failures as a broke/fix maintenance item. Consequently, this finding has a crosscutting aspect in the area of human performance associated with the resources component because the licensee failed to minimize long-standing equipment issues
[H.2(a)]  (Section 1R04).
: '''Green.'''
The inspectors reviewed a self-revealing noncited violation of Technical Specification 5.4.1 for the licensee's failure to determine the appropriate preventive maintenance strategy and task frequency for the reactor core isolation cooling system turbine lube oil cooler inlet pressure control valve (E51-PCVF015). The vendor m anual for the pressure control valve recommends that non-metallic parts (including diaphragms)be replaced after 5 years in service. On October 13, 2010, after being in service for more than ten years without diaphragm replacement, the valve developed a leak that rendered the reactor core isolation cooling system inoperable. The licensee replaced the damaged diaphragm and created a preventive maintenance activity for its periodically replacement. This issue was entered into the licensee's corrective action program as Condition Report CR
-RBS-2010-05224. This finding was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affect ed the associated cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the subject performance deficiency allowed a failure to occur that rendered the reactor core isolation cooling system inoperable for approximately 14 hours. Because this finding occurred while the unit was operating at full power, the inspectors used Inspection Manual Chapter 0609, Attachment 4, "Phase 1 - Initial Screening and Characterization of Findings," to assess its risk significance. The reactor core isolation cooling diaphragm failure was determined to have occurred when the pump was secured; that is, the pump could have operated for 24 hours if it had not been shut down at that time.
 
Therefore , the exposure time was equal to the repair time, which was 15.5 hours. The finding involved a loss of safety system function and therefore did not screen in Phase 1, requiring a Phase 2 evaluation.
 
The inspectors used the Phase 2 pre-solved spreadsheet with a duration of 0-3 days to determine that the issue had very low significance (Green). The inspectors concurred with the licensee's determination that a "lack of technical rigor" had been the reason why the preventive maintenance evaluation of valve E51-PCVF015 had been incorrect, and was therefore the major contributor to the finding. The inspectors considered that this contributor does not reflect current licensee performance because this contributor is a human performance error that occurred in September 2006, and because in 2007, the licensee developed corrective actions to address a substantive crosscutting issue in human performance. Those actions are described in Condition Report CR
-RBS-2007-00835 and included activities that changed the licensee's human performance program such that the human performance error that occurred in September of 2006 is not likely to re-occur. This finding therefore does not have a crosscutting aspect (Section 1R12).
: '''Green.'''
The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," involving an inadequate control rod inspection procedure.
 
Specifically, the station's procedures only required inspection of a only 20 percent of the control rods that exceeded the inspection criteria, instead of all of them
. The station currently has 18 CR 82M control rods in the reactor core in shutdown locations that have exceeded Westinghouse's inspection threshold exposure limits.
 
In response to the inspectors' inquries, the licensee reviewed the ir water chemistry and concluded the current tritium and boron levels indicated there was margin for control rod operability. The licensee intends to monitor the reactor coolant for increasing boron and tritium levels throughout this operating cycle. The licensee placed this issue into their corrective action program as Condition Report CR-RBS-2011-01704. The finding is more than minor because it is associated with the equipment performance attribute of the reactor safety Mitigating Systems Cornerstone, and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, "Significance Determination Process," Phase 1 Worksheet, the finding is determined to be of very low safety significance (Green) because it did not result in a loss of system safety function. The inspectors determined that the apparent cause of the performance deficiency was River Bend Station's failure to communicate relevant operating experience to affected internal and external stakeholders. This finding has a crosscutting aspect in the area of problem identification and resolution associated with the operating experience component because the licensee failed to appropriately apply all the CR 82M control rod inspection requirements provided by the control rod vendor [P.2(b)]
(Section 1R20).
 
===Cornerstone: Barrier Integrity===
: '''Green.'''
The inspector identified a Green noncited violation of Technical Specification 5.4.1.a, "Procedures" for River Bend Station fuel handling personnel failing to follow AOP
-0027, "Fuel Handling Mishaps
," when an actual fuel handling event occurred. Instead of entering the AOP, fuel handling personnel continued to move a fuel assembly after equipment damage and potential fuel damage.
 
The licensee entered this issue into their corrective action program as Condition Report CR
-RBS-2011-03692. This failure to follow procedures is a performance deficiency. The performance deficiency is more that minor, and therefore a finding, because it adversely impacted the human performance attribute of the barrier integrity cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding) protect the public from radionuclide releases caused by accidents or events. Using Manual Chapter 0609, "Significance Determination Process," Phase 1 worksheets, the inspector determined the finding had very low safety significance (Green) because the fuel cladding barrier was potentially degraded but there was no release of radionuclides. This finding has a crosscutting aspect in the area of problem identification and resolution associated with the operating experience component because the licensee failed to implement and institutionalize operating experience through changes to station procedures and training programs [P.2(b)] (Section 4OA3).
: '''Green.'''
The inspector identified a finding for failure to follow River Bend Station's "Fuel Handling Guideline."  A fuel handling event occurred at River Bend Station on January 21, 2011 , when a fuel assembly was grappled and raised approximately one foot rather than fully withdrawn from the core. With the fuel assembly only partially withdrawn from the core, the refuel platform was erroneously moved horizontally approximately five feet. This inappropriate stop at one foot followed by inappropriate horizontal movement of the refuel platform with the fuel partially inserted into the core resulted in equipment damage and potential fuel damage. The licensee entered this issue into their corrective action program as Condition Report CR
-RBS-2011-03693. This failure to follow the guideline is a performance deficiency. The performance deficiency is more that minor, and therefore a finding, because it adversely impacted the human performance attribute of the Barrier Integrity Cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding) protect the public from radionuclide releases caused by accidents or events. Using Manual Chapter 0609, "Significance Determination Process," Phase 1 worksheets, the inspector determined the finding had very low safety significance (Green) because the fuel cladding barrier was potentially degraded but there was no release of radionuclides. This finding has a crosscutting aspect in the area of human performance associated with the decision making component because the licensee made a safety-significant decision without verifying the validity of underlying assumptions [H.1(b)] (Section 4OA3).
 
===Cornerstone: Emergency Preparedness===
: '''Green.'''
The inspector identified a Severity Level IV noncited violation of 10 CFR 50.54(q) for changes to the licensee's emergency plans that decreased the effectiveness of those plans without NRC approval. Specifically, the effectiveness of River Bend Station Emergency Plan, Revision 36, was reduced by removal of the Health Physics Communicator position from the emergency response organization. The licensee's failure to recognize that Revision 36 decreased the effectiveness of licensee emergency plans was a performance deficiency.
 
The licensee has entered this issue into their corrective action system as CR-RBS-20 11-02366 (Section 1EP4).
 
This finding is more than minor because it has a potential effect on the licensee's emergency response capabilities and because the licensee may not be capable of implementing adequate measures to protect the health and safety of the public when the effectiveness of its emergency response organization has been reduced. The finding was evaluated using the NRC Enforcement Policy because it impeded the regulatory process as defined by Manual Chapter 0609, Appendix B, Section 2.2(e).
 
The finding was determined to be Severity Level IV because it decreased the licensee's ability to meet or implement a regulatory requirement not related to assessment or notification.
 
===Cornerstone: Occupational Radiation Safety===
: '''Green.'''
The inspectors identified a noncited violation of Technical Specification 5.7.2 for failure to properly control and guard a high radiation area with dose rates greater than or equal to 1000 mrem/hr. Specifically, on January 25, 2011, while touring the outside area between the auxiliary building and the radioactive waste building, the inspectors noted that the access gate to a locked high radiation area was open. A guard for the locked high radiation area was positioned in a tent enclosure to the right of the gate, but was not in a position to maintain "line-of-sight" control of the access to the locked high radiation area. The licensee immediately repositioned the guard and enhanced the tent construction to provide the necessary control for access to the area. The licensee placed this issue into the ir corrective action program as CR 2011-01154. The finding was more than minor because it was associated with the Occupational Radiation Safety Cornerstone attribute (exposure control) of program and process and affected the cornerstone objective, in that, the failure to properly control access to a high radiation area with dose rates in excess of 1000 mrem/hr had the potential to increase personnel dose. Using the Occupational Radiation Safety Significance Determination Process, the inspectors determined the finding to have very low safety significance because it was not associated with ALARA planning or work controls, there was no overexposure, there was no substantial potential for an overexposure, and the ability to assess dose was not compromised. The finding has a human performance crosscutting aspect associated with work control , work planning activities, because the individuals failed to consider job site conditions which would impact the ability of the guard to adequately observe the entrance to the locked high radiation area [H.3(a)] (Section 2RS01).
 
===B. Licensee-Identified Violations===
 
A violation of very low safety significance, which w as identified by the licensee, ha s been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensee's corrective action program.

===.1 Partial Walkdown===
 
a. The inspectors performed partial system walkdowns of the following risk
-significant systems: Inspection Scope High pressure core spray system following system maintenance Division 1 control building chiller system walkdown during Division 2 outage Division 1 standby service water system walkdown during Division 2 outage The inspectors selected these systems based on their risk significance relative to the reactor safety cornerstones at the time they were inspected. The inspectors attempted to identify any discrepancies that could affect the function of the system, and, therefore, potentially increase risk. The inspectors reviewed applicable operating procedures, system diagrams, Updated Safety Analysis Report, technical specification requirements, administrative technical specifications, outstanding work orders, condition reports, and the impact of ongoing work activities on redundant trains of equipment in order to identify conditions that could have rendered the systems incapable of performing their intended functions. The inspectors also inspected accessible portions of the systems to verify system components and support equipment were aligned correctly and operable. The inspectors examined the material condition of the components and observed operating parameters of equipment to verify that there were no obvious deficiencies. The inspectors also verified that the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact the capability of mitigating systems or barriers and entered them into the corrective action program with the appropriate significance characterization. Specific documents reviewed during this inspection are listed in the attachment.
 
These activities constitute completion of three partial system walkdown sample s as defined in Inspection Procedure 71111.04-05. Also, additional activities were performed during this system walkdown that were associated with TI 2515/177, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems."  These activities are described in bullet

b. Introduction
. The inspectors identified a Green noncited violation of 10 CFR Part 50, Appendix B, Criterion XVI, "Corrective Action," for failure to promptly identify and correct adverse service water chemistry conditions to resolve repetitive service water pressure control valves diaphragm failures that affected operability of the control building chillers.
 
Findings Description
. On January 18, 2011, the inspectors performed a walk down of the control building chillers. During the walk down, the inspectors identified that control building chiller condenser A service water pressure control valve, 1SWP-PVY32A, had failed open allowing condenser pressure to decrease low out of specification. Plant operators subsequently declared control building chiller A inoperable. Control building chiller condenser A service water pressure control valves automatically limit cooling water flow through their respective control building chiller condenser to maintain refrigerant temperature and pressure within a preset design range for chiller operability.
 
The station replaced pressure control valve 1SWP-PVY32A which was recently rebuilt by the original manufacturer, and installed in the system less than two months earlier. When disassembled, the station found that the diaphragm had been breached by a hole 1.5 inches long that was located in the same general area as previous diaphragm failures. I nspection of the valve's internal surfaces revealed that the valve surfaces were very rough from "rust barnacles" in the upper and lower diaphragm cavities. Previous diaphragm failures had also been attributed to rust adhesion and abrasion in the upper and lower diaphragm cavities.
 
The chemistry department asserted that the normal service water chemistry is adequate to prevent rust formation in an operating system.
 
However, when the chillers are out of service, no water flows through 1SWP-PVY32A , so during constant chiller load conditions
, service water can stagnate at the diaphragm pressure boundary and contribute to rust formation.
 
The inspectors reviewed corrective action program documents and noted similar 1SWP-PVY32A diaphr a gm failures as early as 19 99. From 1999 to present , the inspectors found 13 examples of control building chiller pressure control valve failures that were likely due to diaphragm failures
. The inspectors found that the licensee had not completed apparent
-cause evaluations for the diaphragm failures documented in 2010, and had not taken actions to increase system monitoring by operations.
 
In response to the inspectors' inquiries, station personnel completed an apparent cause evaluation of the 1SWP-PVY32 diaphragm failure. That evaluation, documented in CR-RBS-2011-0 2126, determined that vendor reports in 2001 and 2010 had identified that corrosion on 1SWP-PVY32 internal mating surfaces had accelerated the rate of valve diaphragm failures. According to the vendor, a s 1SWP-PVY32A adjust s position to control service water flow to the chiller, the rubber diaphragm change s shape as the diaphragm piston position in the valve raises or lowers.
 
Rust barnacles inhibit diaphragm movement and result in diaphragm fabric wear, which creates holes in the diaphragm and ultimately can lead to loss of control of service water flow to the chiller.
 
To improve diaphragm reliability, the vendor recommended replacing steel body, cover
, and internals with stainless steel. In January 2003, the licensee had initiated engineering request ER
-RB-2003-0009,    "SWP-PVY32A/B/C/D Improvements," to upgrade the valve and piston to stainless steel per the manufacturer's recommendation. This modification was later cancelled. Afterwards
, the station operated until 2010 with these valves often gagged open due to the valve not controlling condenser pressure. Recently , station management implemented corrective actions to consider replacing the carbon steel valves with stainless steel models to preclude corrosion around the diaphragm, allowing the piston to move freely without damaging the diaphragm.
 
=====Analysis.=====
The failure to promptly identify and correct adverse service water chemistry conditions, permitted rust barnacle build up in SWP*PVY32A, a condition that resulted in valve diaphragm failures and is a performance deficiency.
 
The finding was more than minor because it was associated with the equipment performance attribute of the reactor safety Mitigating Cornerstone, and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences, in that this finding caused unplanned unavailability of control building chillers. Using Inspection Manual Chapter 0609, "Significance Determination Process," Phase 1 Worksheet, the inspectors determined that the finding was of very low safety significance (Green), because it did not result in a loss of system safety function.
 
The inspectors determined that the apparent cause of the performance deficiency was the repetitive failure of 1SWP-PVY32 diaphragm from rust barnacles that formed during low flow conditions on the valve internal steel parts.
 
The apparent cause of the performance deficiency was the station's failure to thoroughly evaluate the cause of the corrosion build up mechanism because the station treated diaphragm failures as a broke/fix maintenance item. This finding has a crosscutting aspect in the area of human performance associated with the resource component because the licensee failed to minimize long
-standing equipment issues [H.2(a)].
Enforcement
. Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion XVI, "Corrective Action," states that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected.
 
Contrary to the above, from 1999 to 2011, station management failed to control service water chemistry to prevent excessive internal corrosion product valves, 1SWP
-PVY32A, B, C, and D, which resulted in repetitive diaphragm failures that adversely affected operability of the control building chillers. Because this finding was of very low safety significance and was entered into the licensee's corrective action program as Condition Report CR
-RBS-2011-0 2126, this violation is being treated as a noncited violation consistent with the NRC Enforcement Policy:  NCV 05000458/2011002
-01 , "Repetitive Service Water Pressure Control Valves Diaphragm Failures Affecting Control Building Chillers Operability.

===.2 Complete Walkdown===
 
a. On January 21, 2011, the inspectors performed a complete system alignment inspection of the Division 2 residual heat removal system to verify the functional capability of the Inspection Scope system. The inspectors selected this system because it was considered both safety and risk significant in the licensee's probabilistic risk assessment. The inspectors walked down the system to review mechanical and electrical equipment configurations, electrical power availability, system pressure and temperature indications, component labeling, component lubrication, component and equipment cooling, hangers and supports, and operability of support systems, as appropriate. The inspectors also verified that ancillary equipment or debris did not interfere with equipment operation. The inspectors reviewed a sample of past and outstanding work orders to determine whether any deficiencies significantly affected the system function. In addition, the inspectors reviewed the corrective action program database to ensure that system equipment alignment problems were being identified and appropriately resolved. Specific documents reviewed during this inspection are listed in the attachment.
 
Also, additional activities were performed during this system walkdown that were associated with TI 2515/177, "Managing Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems."  These activities are described following bullet

Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems" On January 21, 2011, the inspectors conducted a walkdown of the Division 2 residual heat removal system in sufficient detail to reasonably assure the acceptability of the licensee's walkdowns (TI 2515/177, Section 04.0 2.d). Inspection Scope In addition, the inspectors verified that the licensee ha d isometric drawings that describe the Division 2 residual heat removal system configurations and ha d acceptably confirmed the accuracy of the drawings (TI 2515/177, Section 04.0 2.a). The inspectors verified the following related to the isometric drawings:
High point vents were identified
.
 
High points that do not have vents were acceptably recognizable.
 
Other areas where gas can accumulate and potentially impact subject system operability, such as at orifices in horizontal pipes, isolated branch lines, heat exchangers, improperly sloped piping, and under closed valves, were acceptably described in the drawings or in referenced documentation.
 
Horizontal pipe centerline elevation deviations and pipe slopes in nominally horizontal lines that exceed specified criteria were identified.
 
All pipes and fittings were clearly shown.
 
The drawings were up-to-date with respect to recent hardware changes and that any discrepancies between as
-built configurations and the drawings were documented and entered into the corrective action program for resolution. The inspectors verified that Piping and Instrumentation Diagrams (P&IDs) accurately describe d the subject systems, that they were up-to-date with respect to recent hardware changes, and any discrepancies between as
-built configurations, the isometric drawings, and the P&IDs were documented and entered into the corrective action program for resolution (TI 2515/177, Section 04.0 2.b). Specific documents reviewed during this inspection are listed in the attachment.
 
This inspection effort counts towards the completion of TI 2515/177, which will be closed in a later inspection report.

=====Introduction.=====
The inspectors reviewed a green self-revealing noncited violation of Technical Specification 5.4.1 for the licensee's failure to determine the appropriate preventive maintenance strategy and task frequency for the reactor core isolation cooling system turbine lube oil cooler inlet pressure control valve (E51-PCVF015). Findings Description
. On July 7, 2000, the licensee installed a diaphragm in the reactor core isolation cooling system turbine lube oil cooler inlet pressure control valve (E51-PCVF015), while rebuilding that valve. Between that time and October 13, 2010 , the diaphragm was not replaced. O n September 25, 2006, the licensee had completed a preventive maintenance evaluation of valve E51-PCVF015. That evaluation stated that a review of Vendor Manual T020
-0127 found that no specific maintenance was required for this valve. Consequently, because that evaluation found no information that indicated that preventive maintenance was desirable, the licensee did not develop a preventive maintenance schedule to specify inspection or replacement of the diaphragm.
 
On October 13, 2010, a few months more than 10 years after the diaphragm on valve E51-PCVF015 had been installed, it developed a leak that rendered the valve inoperable. The licensee replaced the diaphragm and returned the valve to service approximately 14 hours after the leak was discovered. The licensee's investigation of the cause of this leak was documented in Condition Report CR
-RBS-2010-05224. That investigation determined, in part, that Vendor Manual T020
-0127 had recommended that non-metallic parts (including diaphragms)be replaced after 5 years in service. The investigation also determined that a "lack of technical rigor" had been the reason why the preventive maintenance evaluation of valve E51-PCVF015 had been incorrect.
 
In Condition Report CR
-RBS-2010-05224, corrective action #8 corrected the preventive maintenance evaluation of valve E51-PCVF015 and corrective action #9 created a preventive maintenance activity to periodically replace the diaphragm on that valve.
 
=====Analysis.=====
The licensee's failure to determine the appropriate preventive maintenance strategy and task frequency for the reactor core isolation cooling system turbine lube oil cooler inlet pressure control valve was a performance deficiency. This performance deficiency was more than minor and was therefore a finding because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affect ed the associated cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences, in that the subject performance deficiency allowed a failure to occur that rendered the reactor core isolation cooling system inoperable for approximately 14 hours. Because this finding occurred while the unit was operating at full power, the inspectors used Inspection Manual Chapter 0609, Attachment 4, "Phase 1 - Initial Screening and Characterization of Findings," to assess its risk significance. The reactor core isolation cooling diaphragm failure was determined to have occurred when the pump was secured; that is, the pump could have operated for 24 hours if it had not been shut down at that time.
 
Therefore , the exposure time was equal to the repair time, which was 15.5 hours. The finding involved a loss of safety system function and therefore did not screen in Phase 1, requiring a Phase 2 evaluation. Using the Phase 2 pre-solved spreadsheet, for 0
-3 days, the issue screened as having very low significance (Green). The inspectors concurred with the licensee's determination that a "lack of technical rigor" had been the reason why the preventive maintenance evaluation of valve E51-PCVF015 had been incorrect, and was therefore the major contributor to the finding. The inspectors considered that this contributor does not reflect current licensee performance because this contributor is a human performance error that occurred in September 2006, and because in 2007, the licensee developed corrective actions to address a substantive crosscutting issue in human performance. Those actions are described in Condition Report CR
-RBS-2007-00835 and included activities that changed the licensee's human performance program such that the human performance error that occurred in September of 2006 is not likely to re
-occur. This finding therefore does not have a crosscutting aspect.
 
=====Enforcement.=====
Technical Specification 5.4.1 requires, in part, that written procedures shall be implemented covering the procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978.
 
Regulatory Guide 1.33, Section 9, requires that preventive maintenance schedules should be developed to specify, in part, inspection or replacement of parts that have a specific lifetime. Procedure E N-DC-335, "[Preventive Maintenance] Basis Template
," Revision 2, required the licensee, in part, to evaluate industry experience, including relevant information from vendors, to determine the appropriate preventive maintenance strategy and task frequency for the component being evaluated.
 
Contrary to the above, on September 25, 2006, the licensee did not implement EN
-DC-335, a written procedure for developing preventive maintenance schedules for inspection or replacement of parts that have a specific lifetime, in that the licensee did not evaluate relevant information from vendors to determine the appropriate preventive maintenance strategy and task frequency for valve E51
-PCVF015. Specifically, in the preventive maintenance evaluation completed on that date, the licensee determined that Vendor Manual T020
-0127 for the subject valve required no specific maintenance for this model valve, when in fact
, Section 5.11 of that manual recommended that non
-metallic parts be replaced after five years in service.
 
This violation is addressed in the licensee's corrective action program as Condition Report CR-RBS-2010-05224. Because this violation was of very low safety significance and was entered into the licensee's corrective action program, this violation is being treated as a noncited violation consistent with the NRC Enforcement Policy
:
NCV 05000458/2011002-02 , "Failure to Determine the Appropriate Preventive Maintenance Strategy and Task Frequency for the Reactor Core Isolation Cooling System Turbine L ube O il Cooler Inlet Pressure Control Valve."

==1R13 Maintenance Risk Assessments and Emergent Work Control==
{{IP sample|IP=IP 71111.13}}
a. The inspectors reviewed licensee personnel's evaluation and management of plant risk for the maintenance and emergent work activities affecting risk
-significant and safety
-related equipment listed below to verify that the appropriate risk assessments were performed prior to removing equipment for work:
Inspection Scope Diesel availability during fuel oil transfer surveillance, January 4, 2011
 
Transformer yard scaffolding, January 11, 2011
 
Evaluation of outage risk with single source of service water available, January 20, 2011  Non-divisional work week, March 7, 2011  Fancy Point meter and relay calibration, and channel integrity testing, March 8 and 9, 2011 Feed pump oil leak, March 14, 2011 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 licensee personnel performed risk assessments as required by 10 CFR 50.65(a)(4) and that the assessments were accurate and complete. When licensee personnel performed emergent work, the inspectors verified that the licensee personnel promptly assessed and managed plant risk. The inspectors reviewed the scope of maintenance work, discussed the results of the assessment with the licensee's probabilistic risk analyst or shift technical advisor, and verified plant conditions were consistent with the risk assessment. The inspectors also reviewed the technical specification requirements and inspected portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met. Specific documents reviewed during this inspection are listed in the attachment.
 
These activities constitute completion of six maintenance risk assessments and emergent work control inspection sample s as defined in Inspection Procedure 71111.13-05.

The inspectors evaluated the technical adequacy of the evaluations to ensure that technical specification 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 technical specifications and Updated Safety Analysis Report to the licensee personnel's 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. The inspectors determined, where appropriate, compliance with bounding limitations associated with the evaluations. Additionally, the inspectors also reviewed a sampling of corrective action documents to verify that the licensee was identifying and correcting any deficiencies associated with operability evaluations. Specific documents reviewed during this inspection are listed in the attachment.

. These activities constitute completion of one refueling outage and other outage inspection sample as defined in Inspection Procedure 71111.20-05. b.
 
===.1
 
=====Introduction.=====
===
The inspectors identified a Green noncited violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," involving an inadequate control rod inspection procedure.
 
Findings
 
=====Description.=====
On February 2, 2011, plant personnel discovered two cracks in a Westinghouse CR 82M control rod. The inspectors reviewed the vendor's control rod inspection requirements and acceptance criteria provided in the Westinghouse document "Inspection Guidelines and Operating Experience of CR 82, CR 82M, and CR 82M-1 Westinghouse BWR Control Rods."
 
The document states that the guidelines increase the operational margin for safe control rod operation ensuring that decreased reactivity worth, due to boron carbide loss through control rod cracking, will not become an operability issue, and ensures the ability to scram and maintain control rod structural integrity. The inspectors also reviewed reactor engineering procedure REP
-0053, "Control Rod Visual Inspection," and Entergy corporate procedure EN
-RE-211, "Control Blade Lifetime," to determine if the procedures complied with the Westinghouse inspection criteria. The inspectors found that the station's procedures contained the updated inspection criteria based on control rod exposures, but did not require inspection of each control rod that met the threshold exposure limits. Specifically, the station's procedures required inspection of only a representative 20% sample control rods, instead of all of the control rods that exceeded the inspection criteria. The Westinghouse inspection document, Section 9.2.1.2.1, requires that any CR 82M control rod which has reached the exposure threshold and has been moved to a shutdown location (typically on the core periphery) must be inspected within four years. Eighteen CR 82M control rods in the reactor core have exceeded Westinghouse's inspection threshold exposure limits. Four of the eighteen control rods had been previously inspected in November of 2004 (RF
-12) with no cracks identified. A fifth control rod, which was inspected during the most recent refueling outage (RF
-16), had two cracks identified on two different control blade faces. Plant personnel contacted Westinghouse to review the images of the cracks and plant chemistry data. Westinghouse provided a report which detailed the failure mechanism as irradiation assisted stress corrosion cracking. In addition, the inspectors found that REP-0053 inspected only 4 of 8 cruciform control rod sides that exceeded the Westinghouse, Section 9.2.1.2.1 inspection criteria. The inspection criteria provided by the Westinghouse guidelines did not address partial inspection of the control rods.
 
Station management performed a review of reactor water chemistry specifically for tritium and boron trends during the last two cycles, and concluded that no new control rod cracks had occurred and that the current tritium and boron levels indicate that there is margin for control rod operability. The station will continue to monitor the reactor coolant for increasing boron and tritium levels in the reactor coolant through the next cycle. In addition, corrective actions have been issued to revise the control rod inspection procedure to include the appropriate inspection criteria and complete control rod inspections in the next refuelling outage (RF
-17).
 
=====Analysis.=====
The failure to develop adequate procedure instructions to inspect Westinghouse CR 82M control rods is a performance deficiency. The finding is more than minor because it is associated with the equipment performance attribute of the reactor safety Mitigating Systems Cornerstone, and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609, "Significance Determination Process," Phase 1 Worksheet, the finding is determined to be of very low safety significance (Green) because it did not result in a loss of system safety function. The inspectors determined that the apparent cause of the performance deficiency was River Bend Station's failure to communicate relevant Operating Experience to affected internal and external stake holders.
 
This finding has a crosscutting aspect in the area of problem identification and resolution associated with the operating experience component because the licensee failed to appropriately apply all of the CR 82M control rod inspection requirements provided by the control rod vendor [P.2(b)].
 
=====Enforcement.=====
Title 10 of the Code of Federal Regulations, Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," states that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Instructions, procedures, or drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. The Westinghouse control blade inspection document, "Inspection Guidelines and Operating Experience of CR 82, CR 82M, and CR 82M
-1 Westinghouse BWR Control Rods," Section 9.2.1.2.1, requires that any CR 82M control rod which has reached the exposure threshold and has been moved to a shutdown location must be inspected within four years.
 
Contrary to the above, on or above February 2, 2011, the control blade inspection procedure,  REP-0053, "Control Rod Visual Inspection," Revision 3, failed to include the appropriate qualitative acceptance criteria that all control rods that had exceeded the exposure threshold be inspected. Because this violation was of very low safety significance and was entered into the licensee's corrective action program as Condition Report CR
-RBS-2011-01704, this violation is being treated as a noncited violation consistent with the NRC Enforcement Policy:
NCV 05000458/2011002
-03, "Inadequate Control Rod Inspection Procedure."
 
===.2
 
=====Introduction.=====
===
The inspectors reviewed a self
-revealing finding involving failure to take adequate corrective actions on a degraded feedwater flow controller push
-button, causing a recirculation flow control valve runback, reactor vessel level transient, and a resulting reactor power transient.
 
=====Description.=====
On January 14, 2011, the plant began reducing power to enter Refuelling Outage 16. Plant operators placed the A feedwater level control valve into manual control, per the shutdown operations procedure. The at-the-controls operator pressed and released the close push
-button associated with the A feedwater level controller (C33-R601A) and observed reactor water level decrease as expected. However, unknown to the operator, the push
-button had stuck in the closed position. The operator continued to monitor level, and noted that reactor water level continued to decrease.
 
The operator responded by pressing the open push
-button to bring reactor water level back to normal. Reactor vessel level did not increase as expected, and prior to releasing the open push
-button, reactor vessel level reached the reactor recirculation flow control valve runback setpoint, initiating a runback and decreasing power from 67 percent to 54 percent. The operator observed and tapped the feedwater regulating valve demand meter (which is above the push
-buttons) and observed the A feedwater level controller push
-button pop out from a depressed position.
 
The event investigation found that the controller push
-button became stuck in a depressed position due to dust and dirt accumulating on the internal mechanisms in the push-button and switch. Further investigation found that in 2008, CR
-RBS-2008-05672 had identified a problem with the close push
-button. Work Order 166807 ,  "C33-R601A FWREG Valve A Flow [Controller] Slow Detent Not [Functioning]," was closed, stating that the condition was not repeatable, with a closing statement noting a friction difference between the operation of this push
-button versus the other feedwater level control valve push
-button controls. No actions were taken to address the identified deficiency. An opportunity to identify the need to lubricate or clean the push
-button was missed during the performance of Work Order 166807.
 
=====Analysis.=====
Corporate procedure EN-LI-102, "Corrective Action Process," Revision 10, requires, in part, that corrective actions address the cause or resolve the deficiency. The performance deficiency was the failure to adequately inspect, clean, and test the defective feedwater level controller push
-button to resolve the stated deficiency (identified in a 2008 condition report), resulting in an unplanned power reduction. The inspectors determined that this finding was more than minor because it was associated with the equipment performance attribute of the Initiating Events Cornerstone, and it impacted the cornerstone objective of limiting the likelihood of those events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. The inspectors evaluated this finding using Phase 1 of Inspection Manual Chapter 0609, Appendix A, "Significance Determination of Reactor Inspection Findings for At-Power Situations," and determined it to be of very low safety significance (Green) because it did not contribute to both the likelihood of a reactor trip and the likelihood that mitigation equipment or functions would not be available. The inspectors determined that the apparent cause of the performance deficiency was the failure to thoroughly evaluate the cause of the defective push
-button's stickiness. This finding has a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program component because the licensee failed to adequately review the results of the work order to ensure that the cause and extent of condition of the defective push-button was resolved in a timely manner [P.1(c)].
 
=====Enforcement.=====
No violation of regulatory requirements occurred because corrective action issues related to the feedwater system are outside of the scope of 10 CFR Part 50, Appendix B. Because this finding does not involve a violation and has very low safety significance, it is identified as FIN 05000458/2011002

Gas Accumulation in Emergency Core Cooling, Decay Heat Removal, and Containment Spray Systems" When reviewing STP-203-0201, "HPCS Piping Water Fill and Valve Position Verification
," the inspectors verified that the procedure was acceptable for (1) testing high pressure core spray with power operation, shutdown operation, maintenance, and subject system modifications, (2) void determination and elimination methods, and (3) post-event evaluation
. Inspection Scope The inspectors reviewed procedure s used for conducting surveillances and determination of void volumes to ensure that the void criteria was satisfied and will be reasonably ensured to be satisfied until the next scheduled void surveillance (TI 2515/177, Section 04.03.a). Also, the inspectors reviewed procedure s used for filling and venting the following conditions which may have introduced voids into the subject systems to verify that the procedures acceptably address ed testing for such voids and provide d acceptable processes for their reduction or elimination (TI 2515/177, Section 04.03.b). Specifically, the inspectors verified that:
Gas intrusion prevention, refill, venting, monitoring, trending, evaluation, and void correction activities were acceptably controlled by approved operating procedures (TI 2515/177, Section 04.03.c.1).
 
Procedure s ensur ed the system did not contain voids that may jeopardize operability (TI 2515/177, Section 04.03.c.2).
 
Procedure s establish ed that void criteria were satisfied and will be reasonably ensured to be satisfied until the next scheduled void surveillance (TI 2515/177, Section 04.03.c.3).
 
The licensee entered changes into the corrective action program as needed to ensure acceptable response to issues. In addition, the inspectors confirmed that a clear schedule for completion is included for corrective action program entries that have not been completed (TI 2515/177, Section 04.03.c.5).
 
Procedure s include d independent verification that critical steps were completed (TI 2515/177, Section 04.03.c.6).
 
The inspectors verified the following with respect to surveillance and void detection:
Specified surveillance frequencies were consistent with technical specification surveillance requirements (TI 2515/177, Section 04.03.d.1).
 
Surveillance frequencies were stated or, when conducted more often than required by technical specifications, the process for their determination was described (TI 2515/177, Section 04.03.d.2).
 
Surveillances methods were acceptably established to achieve the needed accuracy (TI 2515/177, Section 04.03.d.3).
 
Surveillance procedure s include d up-to-date acceptance criteria (TI 2515/177, Section 04.03.d.4).
 
Procedure s include d effective follow
-up actions when acceptance criteria are exceeded or when trending indicates that criteria may be approached before the next scheduled surveillance (TI 2515/177, Section 04.03.d.5).
 
Measured void volume uncertainty was considered when comparing test data to acceptance criteria (TI 2515/177, Section 04.03.d.6).
 
Venting procedure s and practice s utilize d criteria such as adequate venting durations and observing a steady stream of water (TI 2515/177, Section 04.03.d.7).
 
An effective sequencing of void removal steps was followed to ensure that gas does not move into previously filled system volumes (TI 2515/177, Section 04.03.d.8).
 
Qualitative void assessment methods included expectations that the void will be significantly less that allowed by acceptance criteria (TI 2515/177, Section 04.03.d.9).
 
Venting results were trended periodically to confirm that the systems are sufficiently full of water and that the venting frequencies are adequate. The inspectors also verified that records on the quantity of gas at each location are maintained and trended as a means of preemptively identifying degrading gas accumulations (TI 2515/177, Section 04.03.d.10).
 
Surveillances were conducted at any location where a void may form, including high points, dead legs, and locations under closed valves in vertical pipes (TI 2515/177, Section 04.03.d.11).
 
The licensee ensure that systems were not pre-conditioned by other procedures that may cause a system to be filled, such as by testing, prior to the void surveillance (TI 2515/177, Section 04.03.d.12).
 
Procedure s include d gas sampling for unexpected void increases if the source of the void is unknown and sampling is needed to assist in determining the source (TI 2515/177, Section 04.03.d.13).
 
The inspectors verified the following with respect to filling and venting:
Revisions to fill and vent procedure s to address new vents or different venting sequences were acceptably accomplished (TI 2515/177, Section 04.03.e.1).
 
Fill and vent procedure s provide d instructions to modify restoration guidance to address changes in maintenance work scope or to reflect different boundaries from those assumed in the procedure (TI 2515/177, Section 04.03.e.2).
 
The inspectors verified the following with respect to void control:
Void removal methods were acceptably addressed by approved procedures (TI 2515/177, Section 04.03.f.1).
 
The licensee ha d reasonably ensured that the "HPCS Piping Water Fill and Valve Position Verification" pump is free of damage following a gas
-related event in which pump acceptance criteria was exceeded (TI 2515/177, Section 04.03.f.2).

====b. Findings====
Introduction
. A Severity Level IV noncited violation was identified for the licensee having decreased the effectiveness of their emergency plan without having obtained prior approval from the Commission, as required by 10 CFR 50.54(q).
 
=====Description.=====
The NRC identified the licensee's decreasing the effectiveness of their emergency plan without NRC approval as a performance deficiency. Specifically, the effectiveness of the River Bend Station Emergency Plan, Revision 36, was reduced by removal of the Health Physics Network Communicator position from the emergency response organization.
 
The inspector determined that River Bend Station Emergency Plan, Revision 36, removed the Health Physics Network Communicator position from the emergency response organization and transferred the communication function to the Radiological Assessment Coordinator.
 
The revised Radiological Assessment Coordinator duties included acting as Emergency Operations Facility group leader for radiation protection, oversight and approval of dose assessment, development of protective action recommendations for the public, and communication to the NRC.
 
The inspector concluded that due to the increased responsibilities during an emergency the Radiological Assessment Coordinator would be unable to simultaneously perform all of the duties assigned by Emergency Plan Revision 36.
 
Procedure EIP 020, "Emergency Operations Facility," Revision 34, allowed for the ad hoc staffing of the Health Physics Network to relieve the Radiological Assessment Coordinator of communicator duties but did not require a communicator be assigned.
 
The inspector concluded the procedure did not ensure the Radiological Assessment Coordinator would delegate communication duties or that that a person knowledgeable about emergency response, plant health physics, and dose assessment would be assigned as ad hoc Communicator.
 
The inspector s concluded that the licensee could reasonably foresee the need for continuous staffing of the Health Physics Network based on Generic Letter 91
-14, "Emergency Telecommunications," dated September 23, 1991, which in part, defines the Health Physics Network as an essential emergency communication function. Therefore, the inspector s determined removal of the Health Physics Communicator position from the licensee's emergency response organization decreased the effectiveness of their emergency plan.
 
=====Analysis.=====
A licensee making changes to its emergency plan that decreased the effectiveness of those plans without prior Commission approval is a performance deficiency within the licensee's ability to foresee and correct. This finding is more than minor because it has a potential effect on the licensee's emergency response capabilities and because the licensee may not be capable of implementing adequate measures to protect the health and safety of the public when the effectiveness of its emergency response organization has been reduced. The finding was associated with a violation of NRC requirements. This finding was evaluated using the NRC Enforcement Policy because it impeded the regulatory process as defined by Manual Chapter 0609, Appendix B, Section 2.2(e).
 
The finding was determined to be Severity Level IV because it decreased the licensee's ability to meet or implement a regulatory requirement not related to assessment or notification. Although the Health Physics Network Communicator position could have been staffed during an emergency, staffing could have been inappropriately delayed, and procedures did not ensure a knowledgeable person would be assigned as ad hoc communicator
.
 
=====Enforcement.=====
Title 10 of the Code of Federal Regulations, Part 50.54(q)states in part, "the-licensee may make changes to these plans without Commission approval only if the changes do not decrease the effectiveness of the plans and the plans, as changed, continue to meet the standards of Sec. 50.47(b) and the requirements of Appendix E to this part.."  Contrary to the above between December 7, 2010, and March 10, 2011, the licensee made changes to their emergency plan without Commission approval that decreased the effectiveness of that plan. Specifically, the effectiveness of the licensee's emergency plan was reduced by removal of the Health Physics Network Communicator position from the emergency response organization. Because this failure is Severity Level IV and has been entered into the licensee's corrective action program as Condition Report CR-RBS-20 11-02366, this violation is being treated as a noncited violation consistent with the NRC Enforcement Policy:

====a. Inspection Scope====
This area was inspected to:  (1)review and assess licensee's performance in assessing the radiological hazards in the workplace associated with licensed activities and the implementation of appropriate radiation monitoring and exposure control measures for both individual and collective exposures, (2) verify the licensee is properly identifying and reporting Occupational Radiation Safety Cornerstone performance indicators, and (3) identify those performance deficiencies that were reportable as a performance indicator and which may have represented a substantial potential for overexposure of the worker.
 
The inspectors used the requirements in 10 CFR Part 20, the technical specifications, and the licensee's procedures required by technical specifications as criteria for determining compliance. During the inspection, the inspectors interviewed the radiation protection manager, radiation protection supervisors, and radiation workers. The inspectors performed walkdowns of various portions of the plant, performed independent radiation dose rate measurements and reviewed the following items:
Performance indicator events and associated documentation reported by the licensee in the Occupational Radiation Safety Cornerstone The hazard assessment program, including a review of the license's evaluations of changes in plant operations and radiological surveys to detect dose rates, airborne radioactivity, and surface contamination levels Instructions and notices to workers, including labeling or marking containers of radioactive material, radiation work permits, actions for electronic dosimeter alarms, and changes to radiological conditions Programs and processes for control of sealed sources and release of potentially contaminated material from the radiologically controlled area, including survey performance, instrument sensitivity, release criteria, procedural guidance, and sealed source accountability Radiological hazards control and work coverage, including the adequacy of surveys, radiation protection job coverage, and contamination controls; the use of electronic dosimeters in high noise areas; dosimetry placement; airborne radioactivity monitoring; controls for highly activated or contaminated materials (non-fuel) stored within spent fuel and other storage pools; and posting and physical controls for high radiation areas and very high radiation areas Radiation worker and radiation protection technician performance with respect to radiation protection work requirements Audits, self
-assessments, and corrective action documents related to radiological hazard assessment and exposure controls since the last inspection Specific documents reviewed during this inspection are listed in the attachment.
 
These activities constitute completion of the one required sample as defined in Inspection Procedure 71124.01-05.
 
====b. Findings====
 
=====Introduction.=====
The inspectors identified a noncited violation of Technical Specification 5.7.2 for failure to properly control and guard the entrance to a high radiation area with dose rates greater than or equal to 1000 mrem/hr.
 
=====Description.=====
On January 25, 2011, during a tour of areas outside the plant buildings, the inspectors, accompanied by a licensee representative, observed radiological postings for access to the area between the auxiliary and radioactive waste buildings where the chemical decontamination equipment was placed. An outer posting identified the area as a radiologically controlled area and required persons entering the area to be on a radiation work permit and have electronic dosimeters to monitor personnel exposure to radiation. A second posting, closer to the chemical decontamination equipment, stated that the area beyond that posting was considered a "locked high radiation area" (a high radiation area with a dose rate greater than 1000 mrem/hr at 30 centimeters from the source of radiation). The inspectors noted the boundary consisted of a temporary fence with a gated entrance approximately 8 feet in width. The entrance was not locked and did not appear to be guarded. The licensee representative with the inspectors shouted and attempted to get the attention of any individual that may be in the area. No response was received. The inspectors investigated and found one individual in a temporary tent enclosure to the right side of the postings, in an area which was intended to be the entrance to the locked high radiation area. When questioned, the individual stated he/she was there to act as a guard for entrance to the locked high radiation area.
 
The inspectors evaluated the position of the guard and determined that the guard could only observe a small section of the right hand side of the gate opening. In addition, the guard would not be able to see individuals approaching the entrance to the locked high radiation area in order to challenge them or verify they were authorized to enter the area.
 
The inspectors confirmed radiological surveys (RBS
-1101-0907 and RBS
-1101-0983) of the chemical decontamination equipment documented an accessible dose rate of    1700 mrem/hr at 30 centimeters from the source of the radiation.
 
The inspectors discussed the situation with radiation protection supervisors. The supervisors immediately repositioned the guard within the tent and enhanced the tent construction so the guard could maintain the entrance to the within line of sight.
 
=====Analysis.=====
The failure to properly guard and control access to a high radiation area with dose rates greater than or equal to 1000 mrem/hr was a performance deficiency. The finding was more than minor because it was associated with the Occupational Radiation Safety Cornerstone attribute (exposure control) of program and process and affected the cornerstone objective, in that, the failure to properly control access to a high radiation area with dose rates in excess of 1000 mrem/hr had the potential to increase personnel dose. Using the Occupational Radiation Safety Significance Determination Process, the inspectors determined the finding to have very low safety significance because it was not associated with ALARA planning or work controls, there was no overexposure, there was no substantial potential for an overexposure, and the ability to assess dose was not compromised. The finding has a human performance crosscutting aspect associated with work control , work planning activities, because the individuals failed to consider job site conditions which would impact the ability of the guard to adequately observe the entrance to the locked high radiation area. [H.3(a)]
 
=====Enforcement.=====
Technical Specification 5.7.2 states, in part, that areas with radiation levels greater than or equal to 1000 mrem/hr shall be provided with locked or continuously guarded doors to prevent unauthorized entry.
 
9.5, "Responsibilities for the Access Control Guard," of licensee's procedure, EN
-RP-101, "Access Control for Radiologically Controlled Areas," Revision 5, states that if the door controlling access to the locked high radiation area is to be left open or cannot be secured/locked when entering, the Access Control Guard shall remain stationed with a direct "line
-of-sight" and control of the door. Contrary to these requirements, on January 25, 2011, the guard at the entrance to the locked high radiation area enclosing the chemical decontamination equipment was not positioned properly to provide direct    line-of-sight control of the entrance. The licensee immediately changed the location of the access control guard and made modifications to the tent area to provide direct    line-of-sight control of the entrance and other modifications to provide better observation of individuals approaching the area. Since this violation was of very low safety significance and was documented in the licensee's corrective action program as Condition Report 2011-1154, it is being treated as a noncited violation consistent with the NRC Enforcement Policy:  NCV 05000458/2011002

of Identification and Resolution of Problems
 
====a. Inspection Scope====
As part of the various baseline inspection procedures discussed in previous sections of this report, the inspector routinely reviewed issues during baseline inspection activities and plant status reviews to verify that they were being entered into the licensee's corrective action program at an appropriate threshold, that adequate attention was being given to timely corrective actions, and that adverse trends were identified and addressed. The inspector reviewed attributes that included:  the complete and accurate identification of the problem; the timely correction, commensurate with the safety significance; the evaluation and disposition of performance issues, generic implications, common causes, contributing factors, root causes, extent of condition reviews, and previous occurrences reviews; and the classification, prioritization, focus, and timeliness of corrective actions. Minor issues entered into the licensee's corrective action progra m because of the inspector' s observations are included in the attached list of documents reviewed. These routine reviews for the identification and resolution of problems did not constitute any additional inspection samples.

===.1 On February 11, 2011===
 
, at 2:38 PM, the main control room received a fire detector alarm for the B recirculation pump in the drywell. The inspectors responded to the control room and observed the stations response.
 
The station was completing refueling outage 16 and the drywell had recently been closed to personnel access. The main control room was unable to determine whether the alarm was valid within fifteen minutes, and therefore entered the emergency action level for a fire within the protected area boundary that is not extinguished within fifteen minutes. The station declared a notification of an unusual event at 1:07 PM and terminated the event at 1:52 PM after verification that the drywell fire alarm was invalid. The inspectors determined that the licensee completed all required fire brigade and emergency response actions per station procedures.

power was at approximately 20 percent. The circulating water pumps were supplying water to the condenser but there were no cooling tower fans in service at this time. The main control room received a smoke detector alarm for 'C' cooling tower. The outside operator reported thick black smoke coming from the circulating water cooling tower C. The main control room dispatched the fire brigade. The fire brigade reported the fire wa s out at 1:09 PM
. River Bend Station NJS-X2C transformer bus was faulted causing significant bus, cable, and switchgear damage and a loss of CWS cooling tower "C" fans. The inspectors responded to the circulating cooling tower C. No emergency action level was declared because the fire was outside of the protected area. The inspectors determined that the licensee completed all required fire brigade and emergency response actions per station procedures.
 
===.3 January 21, 2011 Refuel Equipment Damage and Potential Fuel Damage===
 
====a. Inspection Scope====
On January 21, 2011, fuel handlers were performing core to core fuel movements. The refuel platform mast was bent and potential fuel damage occurred when the refuel platform was moved horizontally with a fuel assembly grappled and not fully withdrawn from the core. In addition, on the same day, a different fuel assembly was mispositioned in the spent fuel pool, and on February 4, 2011, another fuel assembly was mispositioned in the reactor core.
 
Region IV sent an operator licensing inspector to complete the inspection sample.
 
On January 21, 2011, three members of the refuel team were on the refuel platform performing core to core moves. These members were the driver, the spotter and the refuel senior reactor operator (RSRO). A fuel assembly was grappled in the core and lifted approximately one foot. The next movement of the refuel platform was a horizontal move of approximately five feet, with the fuel assembly still inserted in the core. This horizontal movement caused damage to the main mast of the refuel platform and potential damage to the fuel assembly. Procedure AOP
-0027, Fuel Handling Mishaps, was not entered at any time during this event. The next movement of the refuel platform was back to the horizontal position corresponding to the grappled fuel assembly that was still only partially lifted out of the core. The fuel assembly was then fully lifted out of the core, moved horizontally to its next core location, and lowered into the core. While lowering the assembly there was a loud noise and vibration of the main mast when a section of the telescoping mast that had been bound became dislodged and fell down to its normal position. There was no unexpected downward movement of the fuel assembly when this section of the mast fell.
 
On January 21, 2011 a fuel assembly was mispositioned in the spent fuel pool.
 
One page of the fuel movement plan was inadvertently skipped, causing this fuel assembly to be moved to the correct location out of sequence.
 
On February 4, 2011 a fuel assembly was loaded into the core in the wrong location. This was discovered on February 5, when a fuel assembly was found in the upper containment pool which should have been loaded previously.
 
From January 30, 2011 through February 2, 2011, one regional inspector interviewed various fuel handling personnel and other plant staff and observed fuel movement in the reactor core. He also reviewed plant records, fuel handling procedures and guidelines.
 
====b. Findings====
(1) Failure To Follow Procedures Introduction
. The inspector identified a Green noncited violation of Technical Specification 5.4.1.a, "Procedures" for River Bend Station fuel handling personnel failing to follow AOP
-0027, "Fuel Handling Mishaps", when an actual fuel handling event occurred. This led to the fuel handling personnel continuing to move a fuel assembly after equipment damage and potential fuel damage.
 
=====Description.=====
On January 21, 2011 the fuel handling team moved the refuel platform horizontally approximately five feet with a fuel assembly grappled and still partially inserted into the reactor core. This damaged the refuel platform main hoist mast and potentially damaged the irradiated fuel assembly. River Bend Station procedure, AOP-0027, "Fuel Handling Mishaps" provides "instructions in the event of a mishap either causing or having the potential to cause damage to the nuclear fuel resulting from" a number of potential causes including "a dropped or damaged irradiated fuel bundle."  One of the symptoms given as an indicator that fuel may have been damaged is "observation of a fuel bundle dropping or striking a fixed object while moving."  The procedure also cautions that "minor bumping of a fuel bundle does not required implementation of this procedure."
 
In reviewing the circumstances, inspectors concluded that, although the bundle in question was not dropped, the bundle was definitely forced against the other bundles surrounding it as the platform moved horizontally and it was subjected to bending forces sufficient to damage the platform mast and potentially damage the irradiated fuel bundle. The inspectors further concluded that these events did not constitute "minor bumping" and that the fuel handling team should have recognized these circumstances as having the potential to damage irradiated fuel and should have implemented the applicable steps of procedure AOP-0027. However, instead of stopping fuel movement and contacting the control room as directed by procedure AOP-0027, the fuel handling team continued the movement of potentially damaged fuel with damaged fuel handling equipment until it was placed in the next core location. A similar failure to recognize the conditions warranting entry into the fuel handling abnormal operating procedure due to the potential for having damage d irradiated fuel was addressed in NRC Inspection Report 05000528/529/530
-2004011 associated with events at Palo Verde in 2002. Information related to this event was considered in River Bend Station's operating experience process but was not adequately incorporated into the River Bend training on implementing AOP
-0027 such that operators at River Bend would recognize that implementing AOP
-0027 was appropriate for conditions that have the potential to damage irradiated fuel, even if indications of radiological consequences are not immediately observed.
 
=====Analysis.=====
This failure to follow procedures is a performance deficiency. The performance deficiency is more than minor, and because it adversely impacted the human performance attribute of the barrier integrity cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding) protect the public from radionuclide releases caused by accidents or events. Using Manual Chapter 0609, "Significance Determination Process," Phase 1 worksheets, the inspectors determined that the finding was of very low safety significance (Green) because the fuel cladding barrier was potentially degraded but there was no release of radionuclides. This finding has a crosscutting aspect in the area o f problem identification and resolution associated with the operating experience component because the licensee failed to implement and institutionalize operating experience through changes to station procedures and training programs [P.2(b)].
 
=====Enforcement.=====
Technical Specifications 5.4.1.a, "Procedures," requires written procedures be established and implemented covering activities in Appendix A of Regulatory Guide 1.33, "Quality Assurance Program Requirements (Operation)," February 1978. This requires "Procedures for Combating Emergencies and Other Significant Events" including "Irradiated Fuel Damage While Refueling."  River Bend Station procedure, AOP
-0027, "Fuel Handling Mishaps" provides "instructions in the event of a mishap either causing or having the potential to cause damage to the nuclear fuel resulting from" a number of potential causes including "a dropped or damaged irradiated fuel bundle."  One of the symptoms given as an indicator that fuel may have been damaged is "observation of a fuel bundle dropping or striking a fixed object while moving."  This procedure directs refueling operations be stopped, control room be contacted, and fuel be placed in a safe position. Contrary to the above, on January 21, 2011, River Bend fuel handling personnel failed to implement a procedure required by Technical Specification 5.4.1.a in that fuel handling personnel failed to implement AOP
-0027 when conditions existed that created the potential to cause damage to the nuclear fuel. Specifically, fuel handling personnel moved the refuel platform approximately five feet horizontally with an irradiated fuel assembly grappled and only partially (approximately one foot) withdrawn from the reactor core. This movement of the bridge generated inappropriate lateral forces on the fuel bundle by pressing it against the adjacent fuel bundles which had the potential to damage the irradiated fuel bundle and generated sufficient force to damage the refueling platform mast. Instead of immediately stopping refueling operations and notifying the control room, as directed by procedure AOP-0027, River Bend operations personnel did not implement procedure AOP-0027 and the refuel crew continued to move the affected fuel assembly to its next core location. The fuel was lifted out of the core, moved horizontally to its new core location and lowered back into the core, even though the main mast of the refuel platform was damaged and the fuel assembly had potentially been damaged. Because this finding is of very low safety significance and the licensee has entered this issue into the corrective action program as Condition Report CR
-RBS-2011-03692, this violation is being treated as a noncited violation:  NCV 05000458/2011002 07, Failure to Implement Procedure AOP
-0027, "Fuel Handling Mishaps."  (2)  Failure to Follow Fuel Handling Guidelines
 
=====Introduction.=====
The inspector identified a Green finding for failure to follow River Bend Station's "Fuel Handling Guideline."  A fuel handling event occurred at River Bend Station on January 21, 2011 when a fuel assembly was grappled and raised approximately one foot rather than fully withdrawn from the core. With the fuel assembly only partially withdrawn from the core, the refuel platform was erroneously moved horizontally approximately five feet. This inappropriate stop at one foot followed by inappropriate horizontal movement of the refuel platform with the fuel partially inserted into the core resulted in equipment damage and potential fuel damage.
 
=====Description.=====
During core alterations, River Bend Station operating procedure FHP-0003, "Refuel Platform Operation" is utilized. However, this procedure does not describe specific steps and responsibilities to safely move fuel in the core. Instead, fuel handlers follow the River Bend Station "Fuel Handling Guideline."  This "Fuel Handling Guideline" is intended to be used in a step
-wise fashion. Step 8 requires the grapple to be raised to the normal up position. The Spotter and the Driver are required to watch both the Z height and weight while a fuel assembly is being raised to the normal up position. The refueling senior reactor operator is required to enforce these requirements. The required actions were neither performed nor enforced.
 
Step 9 then directs the refuel platform be moved to the next location. River Bend fuel handlers began performing step 9 prior to the fuel assembly being lifted to the normal up position per step 8. This horizontal refuel platform movement with the fuel assembly still partially inserted in the core resulted in damage to the refuel platform mast and potential fuel damage.
 
=====Analysis.=====
This failure to follow the licensee's guideline is a performance deficiency. The performance deficiency is more that minor, and therefore a finding, because it adversely impacted the human performance attribute of the barrier integrity cornerstone objective to provide reasonable assurance that physical design barriers (fuel cladding) protect the public from radionuclide releases caused by accidents or events. Using Manual Chapter 0609, "Significance Determination Process," Phase 1 worksheets, the inspectors determined that the finding was of very low safety significance because the fuel cladding barrier was potentially degraded but there was no release of radionuclides. This finding has a crosscutting aspect in the area of human performance associated with the decision making component because the licensee made a safety
-significant decision without verifying the validity of underlying assumptions [H.1(b)].
 
=====Enforcement.=====
River Bend Station fuel handlers rely on the instructions contained in "Fuel Handling Guideline," Revision 3 and on skill of the craft to conduct core alterations. This procedure contains a "General Grappling Procedure" which is followed in a step
-wise fashion. Step 8 requires the grapple to be raised to the normal up position. The spotter and driver are expected to perform this step and the refueling senior reactor operator is expected to enforce these actions. Step 9 then directs the refuel platform be moved to the next location. Contrary to this instruction, River Bend Fuel Handlers began performing step 9 prior to the completion of step 8.
 
This resulted in damage to the fuel handling equipment and potential damage to the irradiated fuel. This movement continued for more than 10 seconds due to the inattention of the fuel handling crew. This failure to follow a facility standard is a performance deficiency. Condition Report CR
-RBS-2011-03693 was initiated. Because this finding is of very low safety significance, it is identified as a FIN. FIN 05000458/2011002
-08 "Failure to follow Fuel Handling Guidelines."

==4OA7 Licensee-Identified Violations==
 
The following violation of very low safety significance (Green) w as identified by the licensee and is a violation of NRC requirements which meet s the criteria of Section 2.3.2 of the NRC Enforcement Policy for being dispositioned as noncited violations.
 
===.1 Title 10 CFR 20.1703(c)(6) states, in part, that the licensee shall implement and maintain a respiratory protection program that includes written procedures regarding supervision===
 
and training of respirator users. Section 5.4[3] of licensee procedure EN
-RP-504, Revision 4, states that training must be completed prior to fit testing for, and use of, respiratory protection equipment. Contrary to these requirements, on August 03, 2010
, and individual was assigned work in the hot machine shop that required the use of a powered air purifying respirator. Qualifications were incorrectly verified prior to the start of the job. A subsequent follow
-up check of the individual's qualifications indicated the individual was not qualified. The individual immediately exited the area. The violation is considered to be of very low safety significance (green) because it is not an ALARA planning issue, no overexposure and no substantial potential for overexposure, and the licensee's ability to assess dose was not compromised. The issue has been entered into the licensee's corrective action program as condition report CR
-RBS-2010-3635.

SUBJECT: RIVER BEND STATION - NRC INTEGRATED INSPECTION REPORT 05000458/2011002

Dear Mr. Perito:

The purpose of this letter is to notify you that the U.S. Nuclear Regulatory Commission (NRC) Region IV staff will conduct a triennial heat sink inspection at your facility. The inspection will be comprised of one reactor inspector from the NRC Region IV office. The inspection will be conducted in accordance with Inspection Procedure 71111.07T, "Heat Sink Performance." The schedule for the inspection is as follows: onsite inspection: March 14-18, 2011

Experience has shown that this inspection is resource intensive both for the NRC inspectors and your staff. In order to minimize the impact to your onsite resources and to ensure a productive inspection, we have enclosed a request for documents needed for this inspection. Please note that the documents are requested to be provided by March 4, 2011. We request, that during the onsite inspection week, you ensure that copies of analyses, evaluations, or documentation regarding the implementation and maintenance of your heat exchanger program are available. Of specific interest are those documents that establish that your heat exchanger program satisfies NRC regulatory requirements and conforms to applicable NRC guidance. Also, appropriate personnel knowledgeable of safety-related heat exchangers should be available to support the inspector at the site during the inspection.

We have discussed the schedule for this inspection activity with your staff and understand that our regulatory contact for this inspection will be Ms. Kristi Huffstatler of your licensing organization. If there are any questions about this inspection or the material requested, please contact the lead inspector, Ronald A. Kopriva, at 817-860-8104 or by email, ron.kopriva@nrc.gov . In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS).
