SUBJECT: LASALLE COUNTY STATION, UNITS 1 AND 2 NRC INTEGRATED INSPECTION REPORT 05000373/2013004; 05000374/2013004 AND UNIT 2 PRELIMINARY WHITE FINDING Dear Mr. Pacilio:
On September 30, 2013, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your LaSalle County Station, Units 1 and 2.  The enclosed report documents the
inspection results which were discussed on Wednesday, October 2, 2013, with the
Site Vice President, Mr. P. Karaba, and other members of your staff. The enclosed inspection report discusses a finding on Unit 2 that has preliminarily been determined to be White, a finding with low-to-moderate safety significance, that may result in additional NRC inspection.  As described in Section 4OA3 of this report, a self-revealed finding
was identified for the failure of station personnel to follow procedure LOP-CW-10, "Dewatering
the Circulating Water System," Revision 32, on April 25, 2013.  Specifically, operators
performed the waterbox dewatering evolution in a manner inconsistent with procedural guidance by manually adjusting the circulating water isolation valves while the waterbox manways were  open.  Adjustment of the inlet isolation valve caused a loss of isolation resulting in flooding of
the condenser pit and a resultant circulating water pump trip, loss of the normal heat sink, and a
manual reactor scram.  This finding was assessed based on the best available information, using the applicable Significance Determination Process (SDP). The inspectors used Inspection Manual Chapter (IMC) 0609, Appendix A, "The Significance Determination Process (SDP) for Findings At-Power," Exhibit 1, dated June 19, 2012, for the Initiating Events cornerstone.  Because the finding caused a reactor trip AND the loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable
shutdown condition, a detailed risk evaluation was required.  The Senior Reactor Analysts
(SRAs) used the LaSalle Standardized Plant Analysis Risk (SPAR) model to perform the
detailed risk evaluation.  In accordance with Risk Assessment of Operational Events Handbook guidance, the initiating event "Loss of Condenser Heat Sink" was set to 1.0 using the
  M. Pacilio -2- events and condition assessment module of the Systems Analysis Program for Hands-On Integrated Reliability Evaluations (SAPHIRE), Version 8.  The calculated conditional core
damage probability for the event was 1.6E-6, which represents a finding of low to moderate safety significance (White). As described in NRC Inspection Manual Chapter 0612, "Power Reactor Inspection Reports," dated January 24, 2013, a finding may or may not be associated with regulatory non-compliance and, therefore, may or may not result in a violation.  Based on the review of this issue and in accordance with NRC Inspection Manual Chapter 0612, the NRC determined that no violation of a regulatory requirement occurred. In accordance with NRC Inspection Manual Chapter 0609, we intend to complete our evaluation using the best available information and issue our final determination of safety significance
within 90 days of the date of this letter.  The significance determination process encourages an
 
open dialogue between the NRC staff and the lic
ensee; however, the dialogue should not impact the timeliness of the staff's final determination. Before we make a final decision on this matter, we are providing you with an opportunity to
(1) attend a Regulatory Conference where you can present to the NRC your perspective on the facts and assumptions the NRC used to arrive at the finding and assess its significance, or
(2) submit your position on the finding to the NRC in writing.  If you request a Regulatory
Conference, it should be held within 30 days of the receipt of this letter and we encourage you
to submit supporting documentation at least one week prior to the conference in an effort to make the conference more efficient and effective.  The focus of the Regulatory Conference is to discuss the significance of the finding and not necessarily the root cause(s) or corrective action(s) associated with the finding.  If a Regulatory Conference is held, it will be open for
public observation.  If you decide to submit only a written response, such submittal should be sent to the NRC within 30 days of your receipt of this letter.  If you decline to request a
Regulatory Conference or to submit a written response, you relinquish your right to appeal the final SDP determination, in that by not doing either, you fail to meet the appeal requirements
stated in the Prerequisite and Limitation sections
of Attachment 2 of NRC Inspection Manual
Chapter 0609. Please contact Michael Kunowski at (630) 829-9618 and in writing within 10 days from the issue date of this letter to notify the NRC of your intentions.  If we have not heard from you within
10 days, we will continue with our significance determination and enforcement decision.  The final resolution of this matter will be conveyed in a separate correspondence. In addition to the finding discussed above, one self-identified violation of very low safety significance (Green) was identified during this inspection.  This finding was determined to involve a violation of NRC requirements and the NRC is treating it as a non-cited violation (NCV), consistent with Section 2.3.2 of the Enforcement Policy.  If you contest the violation or significance of the NCV, you should provide a response within  30 days of the date of this inspection report, with the basis for your denial, to the U. S. Nuclear
Regulatory Commission, ATTN: Document Control Desk, Washington, DC 20555-0001, with
copies to the Regional Administrator, Region III; the Director, Office of Enforcement, 
U. S. Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident
Inspector at the LaSalle County Station. 
  M. Pacilio -3- If you disagree with the cross-cutting aspect assignment in this report, you should provide a response within 30 days of the date of this inspection report, with the basis for your
disagreement, to the Regional Administrator, Region III, and the NRC Resident Inspector at
LaSalle County Station.  In accordance with Title 10 of the Code of Federal Regulations 2.390, "Public Inspections, Exemptions, Requests for Withholdings," of the NRC's "Rules of Practice," a copy of this letter and its enclosure, and your response (if any) will be available electronically for public inspection in the NRC's Public Document Room or from th
e Publicly Available Records System (PARS) component of NRC's Agencywide Documents Access and Management Sy
stem (ADAMS).  ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html

SUMMARY OF FINDINGS Inspection Report (IR) 05000373/2013004, 05000374/2013004; 07/01/2013-09/30/2013; LaSalle County Station, Units 1 & 2; Followup of Events and Notices of Enforcement Discretion. This report covers a 3-month period of inspection by resident inspectors and announced baseline inspections by regional inspectors.  Two findings were identified during the inspection. 
One finding was preliminarily determined to be White and one finding was determined to be a
Green non-cited violation (NCV).  The significance of inspection findings is indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using IMC 0609, "Significance Determination Process" dated June 2, 2011.  Cross-cutting aspects are
determined using IMC 0310, "Components Within the Cross Cutting Areas" dated October 28,
2011.  All violations of NRC requirements are dispositioned in accordance with the NRC's
Enforcement Policy dated January 28, 2013.  The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process" Revision 4. A. NRC-Identified and Self-Revealed Findings
Cornerstone:  Initiating Events
* Preliminary White:  A self-revealed finding preliminarily determined to be of low-to-moderate safety significance was identified for the licensee's failure to follow procedure LOP-CW-10, "Dewatering the Circulating Water System," Revision 32, on Unit 2. 
Specifically, on April 25, 2013, with Unit 2 at 56 percent power, operators appointed to plan and execute the dewatering of the main condenser waterbox did so in a manner inconsistent with procedural guidance by manually adjusting the circulating water
isolation valves while condenser manways were still open.  The subsequent loss of
isolation led to the flooding of the condenser pit and a resultant circulating water pump
trip, loss of the normal heat sink, and a reactor scram.  The licensee entered this issue into its corrective action program (CAP) as action report (AR) 1506809 and performed a root cause analysis to identify the root and contributing causes of the event, as well as to
determine the appropriate corrective actions, such as providing training and revising procedures. The inspectors determined that the licensee's failure to follow the prescribed steps of procedure LOP-CW-10 was a performance deficiency warranting a significance
determination.  The inspectors used Inspection Manual Chapter (IMC) 0609,  Appendix A, "The Significance Determination Process (SDP) for Findings At-Power," Exhibit 1, dated June 19, 2012, for the Initiating Events cornerstone.  Because the
finding caused a reactor trip AND the loss of mitigation equipment relied upon to
transition the plant from the onset of the trip to a stable shutdown condition, a detailed
risk evaluation was required.  The Senior Reactor Analysts (SRAs) used the LaSalle
Standardized Plant Analysis Risk (SPAR) model to perform the detailed risk evaluation.  In accordance with Risk Assessment of Operational Events Handbook guidance, the initiating event "Loss of Condenser Heat Sink" was set to 1.0 using the events and
condition assessment module of the Systems Analysis Program for Hands-On Integrated Reliability Evaluations (SAPHIRE), Version 8.  The calculated conditional core damage
probability for the event was 1.6E-6, which represents a finding of low-to-moderate safety significance (White).  The finding had a cross-cutting aspect in the area of human performance, decision-making, because the licensee failed to use conservative 
2 Enclosure
assumptions when planning and executing the dewatering evolution.  Specifically, the incorrect assumption that this evolution performed at-power could be treated the same
as when performed during a shutdown condition enabled operators to stray from strict
procedure adherence and into knowledge space (H.1(b)).  (Section 4OA3) Cornerstone:  Mitigating Systems and Barrier Integrity
* Green:  A self-revealed finding of very low safety significance and associated non-cited violation of Title 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," was identified for the failure to have procedures adequate for the
circumstances during long-term operation of the high pressure core spray (HPCS) system on minimum flow.  Specifically, three small holes developed in the Unit 2 HPCS minimum flow line elbow due to cavitation and other flow-related wear caused by
inconsistent procedural guidance regarding operation in the minimum-flow mode. 
The licensee promptly repaired the system leak and entered the issue into its CAP as ARs 1503825 and 1530682, which included the performance of an apparent cause
evaluation.  Further corrective actions included the revision of the affected procedures. The finding was determined to be more than minor because it was associated with the Mitigating Systems and Barrier Integrity cornerstone attributes of Procedure Quality and adversely affected the cornerstone objectives of ensuring the availability, reliability, and
capability of systems that respond to initiating events to prevent undesirable
consequences and providing reasonable assurance that physical design barriers protect
the public from radionuclide releases caused by accidents or events.  Specifically, the procedural guidance given to operate the HPCS system was inadequate to prevent long-term operation of the system in the minimum flow mode of operation, which led to
cavitation and flow-induced wear, causing the failure of the Unit 2 HPCS minimum flow
line and inoperability of the HPCS system as well as the primary containment boundary. 
The inspectors determined that the finding could be evaluated in accordance with 
IMC 0609, Appendix A, "The Significance Determination for Findings At-Power," and Appendix H, "Containment Integrity Significance Determination Process."  Further, it was determined that a phase two risk assessment was necessary because the finding
impacted suppression pool integrity, and through that process, this issue screened as
Green.  The inspectors did not identify a cross-cutting aspect associated with this finding.  (Section 4OA3)

REPORT DETAILS
Summary of Plant Status
Unit 1 The unit began the inspection period operating at full power.  On September 7, 2013, power was reduced to approximately 65 percent for a control rod sequence exchange and scram time testing.  Unit 1 was restored to full power on September 8.
Unit 2 The unit began the inspection period operating at full power.  On August 31, 2013, power was reduced to approximately 65 percent for a control rod sequence exchange and scram time
testing.  Unit 2 was restored to full power on September 1.  Additionally, on September 27,
power was reduced to approximately 60 percent for power suppression testing to identify a
leaking fuel element.  Upon the successful completion of that evolution, Unit 2 was restored to
approximately full power on September 30. 1. REACTOR SAFETY Cornerstones:  Initiating Events, Mitigating Systems, and Barrier Integrity 1R01 Adverse Weather Protection (71111.01) .1 Summer Seasonal Readiness Preparations
a. Inspection Scope
The inspectors reviewed the licensee's preparations for summer weather for selected systems, including conditions that could lead to an extended drought. During the inspection, the inspectors focused on plant specific design features and the licensee's procedures used to mitigate or respond to adverse weather conditions. 
Additionally, the inspectors reviewed the UFSAR and performance requirements for
systems selected for inspection, and verified that operator actions were appropriate as
specified by plant specific procedures.  The inspectors also reviewed CAP items to verify that the licensee was identifying adverse weather issues at an appropriate threshold and entering them into its CAP in accordance with station CAP procedures.  The inspectors'
 
reviews focused specifically on the ultimate heat sink and core standby cooling system (CSCS).  Documents reviewed are listed in the Attachment to this report. This inspection constituted one seasonal adverse weather sample as defined in Inspection Procedure (IP) 71111.01-05. b. Findings
No findings were identified.

1R04 Equipment Alignment (71111.04) .1 Quarterly Partial System Walkdowns
a. Inspection Scope
The inspectors performed partial system walkdowns of the following risk-significant systems: * Unit 1 'A' diesel generator (DG) walkdown following 1 'B' DG idle start;
* Unit 1 standby gas treatment system;
* Unit 1 'A' standby liquid control system; and
* Unit 1 reactor core isolation cooling (RCIC). 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 impact the function of the system and, therefore,
potentially increase risk.  The inspectors reviewed applicable operating procedures,
system diagrams, UFSAR, Technical Specification (TS) requirements, outstanding work orders (WOs), 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 walked down
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 parameter
s 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 CAP
with the appropriate significance characterization.  Documents reviewed are listed in the Attachment to this report. These activities constituted four partial system walkdown samples as defined in
IP 71111.04-05. b. Findings
No findings were identified. .2 Semi-Annual Complete System Walkdown
a. Inspection Scope
On August 22, 2013, the inspectors performed a complete system alignment inspection of the Units 1 and 2 Division II DGs with the Division I DG out of service to verify the
functional capability of the system.  This system was selected because it was considered both safety significant and risk significant in the licensee's probabilistic risk assessment. 
The inspectors walked down the system to review mechanical and electrical equipment lineups; electrical power availability; system pressure and temperature indications, as appropriate; component labeling; component lubrication; component and equipment
cooling; hangers and supports; operability of support systems; and to ensure that
ancillary equipment or debris did not interfere with equipment operation.  A review of a
sample of past and outstanding WOs was performed to determine whether any 
5 Enclosure
deficiencies significantly affected the system
function.  In addition, the inspectors reviewed the CAP database to ensure that system equipment alignment problems were being identified and appropriately resolved.  Documents reviewed are listed in the
Attachment to this report. These activities constituted one complete system walkdown sample as defined in
IP 71111.04-05. b. Findings
No findings were identified. 1R05 Fire Protection (71111.05) .1 Routine Resident Inspector Tours (71111.05Q) a. Inspection Scope
The inspectors conducted fire protection walkdowns which were focused on availability, accessibility, and the condition of firefighting equipment in the following risk-significant plant areas:
* fire zone 2I4 U1 low pressure core spray (LPCS)/RCIC room;
* fire zone 8C4 Unit 2 Division II residual heat removal system southwest corner room; * Unit 1 Division 1 essential switchgear room 4F1;
* Unit 1 Division II DG room 7B2; and
* Unit 2 Division II DG room 8B2. The inspectors reviewed areas to assess if the licensee had implemented a fire protection program that adequately controlled combustibles and ignition sources within
the plant, effectively maintained fire detection and suppression capability, maintained
passive fire protection features in good material condition, and implemented adequate compensatory measures for out-of-service, degraded, or inoperable fire protection equipment, systems, or features in accordance with the licensee's fire plan. 
The inspectors selected fire areas based on their overall contribution to internal fire risk
as documented in the plant's Individual Plant Examination of External Events with later
additional insights, their potential to impact equipment which could initiate or mitigate a plant transient, or their impact on the plant's ability to respond to a security event.  Using the documents listed in the Attachment to this report, the inspectors verified that
fire hoses and extinguishers were in their designated locations and available for
immediate use; that fire detectors and sprinklers were unobstructed; that transient
material loading was within the analyzed limits; and fire doors, dampers, and penetration seals appeared to be in satisfactory condition.  The inspectors also verified that minor issues identified during the inspection were entered into the licensee's CAP.  Documents reviewed are listed in the Attachment to this report. These activities constituted five quarterly fire protection inspection samples as defined in
IP 71111.05-05.

b. Findings
No findings were identified.
1R06 Flooding (71111.06) .1 Internal Flooding
a. Inspection Scope
The inspectors reviewed selected risk-important plant design features and licensee procedures intended to protect the plant and its safety-related equipment from internal flooding events.  The inspectors reviewed flood analyses and design documents, including the UFSAR, engineering calculations, and abnormal operating procedures, to
identify licensee commitments.  In addition, the inspectors reviewed licensee drawings to
identify areas and equipment that may be affected by internal flooding caused by the
failure or misalignment of nearby sources of water, such as the fire suppression or the circulating water systems.  The inspectors also reviewed the licensee's CAP documents with respect to past flood-related items identified in the CAP to verify the adequacy of
the corrective actions.  The inspectors performed a walkdown of the following plant
area(s) to assess the adequacy of watertight doors and verify drains and sumps were clear of debris and were operable, and that the licensee complied with its commitments:
* Unit 1 and Unit 2 CSCS pump rooms and ventilation room dampers.  Documents reviewed are listed in the Attachment to this report.  This inspection constituted one internal flooding sample as defined in IP 71111.06-05. b. Findings
No findings were identified.  .2 Underground Vaults
a. Inspection Scope
The inspectors selected underground bunkers/manholes subject to flooding that contained cables whose failure could disable risk-significant equipment.  The inspectors
determined that the cables were not submerged, that splices were intact, and that appropriate cable support structures were in place, and in cases where the cables were wetted, the licensee had corrective actions in place to address the issue.  In those areas
where dewatering devices were used, such as a sump pump, the inspectors verified the
device was functional/operable and level alarm circuits were set appropriately to ensure
that the cables would not be submerged.  In those areas without dewatering devices, the inspectors verified that drainage of the area was available, or that the cables were qualified for submergence conditions.  The inspectors also reviewed the licensee's CAP
documents with respect to past submerged cable issues identified in the CAP program
to verify the adequacy of the corrective actions.  The inspectors performed a walkdown of manholes 1 through 6, which are subject to flooding. Documents reviewed are listed in the Attachment to this report.

This inspection activity constituted one underground vaults sample as defined in
IP 71111.06-05. b. Findings
No findings were identified. 1R11 Licensed Operator Requalification Program (71111.11) .1 Resident Inspector Quarterly Review of Licensed Operator Requalification (71111.11Q) a. Inspection Scope
On August 8, 2013, the inspectors observed a crew of licensed operators in the plant's simulator during licensed operator requalification training to verify that operator
performance was adequate, evaluators were identifying and documenting crew performance problems, and training was being conducted in accordance with licensee procedures.  The inspectors evaluated the following areas:
* licensed operator performance;
* crew's clarity and formality of communications;
* ability to take timely actions in the conservative direction;
* prioritization, interpretation, and verification of annunciator alarms;
* correct use and implementation of abnormal and emergency procedures;
* control board manipulations;
* oversight and direction from supervisors; and
* ability to identify and implement appropriate TS actions and Emergency Plan actions and notifications. The crew's performance in these areas was compared to pre-established operator action expectations and successful critical task completion requirements.  Documents reviewed are listed in the Attachment to this report. This inspection constituted one quarterly licensed operator requalification program simulator sample as defined in IP 71111.11.
b. Findings
No findings were identified. .2 Resident Inspector Quarterly Observation of Heightened Activity or Risk (71111.11Q) a. Inspection Scope
On September 4, 2013, the inspectors observed control room operators during the performance of the secondary containment leak rate test.  This was an activity that required heightened awareness or was related to increased risk.  The inspectors evaluated the following areas:
* licensed operator performance;
* crew's clarity and formality of communications;
* ability to take timely actions in the conservative direction; 
8 Enclosure
* prioritization, interpretation, and verification of annunciator alarms (if applicable);
* correct use and implementation of procedures;
* control board (or equipment) manipulations;
* oversight and direction from supervisors; and
* ability to identify and implement appropriate TS actions and Emergency Plan actions and notifications (if applicable). The performance in these areas was compared to pre-established operator action expectations, procedural compliance and task completion requirements.  Documents reviewed are listed in the Attachment to this report. This inspection constituted one quarterly licensed operator heightened activity/risk sample as defined in IP 71111.11. b. Findings
No findings were identified. 1R12 Maintenance Effectiveness (71111.12) .1 Routine Quarterly Evaluations
a. Inspection Scope
The inspectors evaluated degraded performance issues involving the following risk-significant systems:
* Unit Common 'B' diesel fire pump following a failure to start;
* Unit 1 circulating water system; and
* Unit 2 circulating water system.  The inspectors reviewed events, such as where ineffective equipment maintenance had resulted in valid or invalid automatic actuations of engineered safeguards systems, and
independently verified the licensee's actions to address system performance or condition problems in terms of the following:
* implementing appropriate work practices;
* identifying and addressing common cause failures;
* scoping of systems in accordance with 10 CFR 50.65(b) of the maintenance rule;
* characterizing system reliability issues for performance;
* charging unavailability for performance;
* trending key parameters for condition monitoring;
* ensuring 10 CFR 50.65(a)(1) or (a)(2) classification or re-classification; and
* verifying appropriate performance criteria for systems, structures, and components /functions classified as (a)(2), or appropriate and adequate goals and corrective actions for systems classified as (a)(1). The inspectors assessed performance issues with respect to the reliability, availability, and condition monitoring of the system.  In addition, the inspectors verified maintenance
effectiveness issues were entered into the CAP with the appropriate significance characterization.  Documents reviewed are listed in the Attachment to this report. 
9 Enclosure
This inspection constituted three quarterly maintenance effectiveness samples as defined in IP 71111.12-05. b. Findings
No findings were identified. 1R13  Maintenance Risk Assessments and Emergent Work Control (71111.13) .1 Maintenance Risk Assessments and Emergent Work Control
a. Inspection Scope
The inspectors reviewed the licensee'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:
* failed fuel inspection;
* 345-kiloVolt (kV) lightning strike on line 0104;
* automatic start of 1 'A' DG cooling water pump results in extended yellow risk condition;
* yellow risk condition for Unit 1 standby gas treatment work; and
* Unit 2 downpower for power suppression testing. These activities were selected based on their potential risk significance relative to the Reactor Safety Cornerstones.  As applicable for each activity, the inspectors verified that risk assessments were performed as required by 10 CFR 50.65(a)(4) and were accurate
and complete.  When emergent work was performed, the inspectors verified that the
plant risk was promptly reassessed and managed.  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 TS requirements and
walked down portions of redundant safety systems, when applicable, to verify risk analysis assumptions were valid and applicable requirements were met.  Documents
reviewed are listed in the Attachment to this report. These maintenance risk assessments and emergent work control activities constituted
five samples as defined in IP 71111.13-05. b. Findings
No findings were identified. 1R15 Operability Determinations and Functional Assessments (71111.15) .1 Operability Evaluations

The inspectors selected these potential operability issues based on the risk significance of the associated components and systems.  The inspectors evaluated the technical adequacy of the evaluations to ensure that TS operability was properly justified and the subject component or system remained available such that no unrecognized increase in risk occurred.  The inspectors compared the operability and design criteria in the
appropriate sections of the TS and UFSAR to the licensee'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 reviewed a sampling of CAP documents to
verify that the licensee was identifying and correcting any deficiencies associated with operability evaluations.  Documents reviewed are listed in the Attachment to this report. This operability inspection constituted five samples as defined in IP 71111.15-05. b. Findings

b. Findings
No findings were identified. .2 Radioactive Material Storage (02.02) a. Inspection Scope
The inspectors selected areas where containers of radioactive waste are stored and evaluated whether the containers were labeled in accordance with 10 CFR 20.1904, "Labeling Containers," or controlled in accordance with 10 CFR 20.1905, "Exemptions to Labeling Requirements," as appropriate.  The inspectors assessed whether the radioactive material storage areas were controlled
and posted in accordance with the requirements of 10 CFR Part 20, "Standards for
Protection Against Radiation."  For materials stored or used in the controlled or
unrestricted areas, the inspectors evaluated whether they were secured against unauthorized removal and controlled in accordance with 10 CFR 20.1801, "Security of Stored Material," and 10 CFR 20.1802, "Control of Material Not in Storage," as appropriate. The inspectors assessed whether the licensee established a process for monitoring the impact of long-term storage (e.g., buildup of any gases produced by waste
decomposition, chemical reactions, container deformation, loss of container integrity, or re-release of free-flowing water) that was sufficient to identify potential unmonitored,
unplanned releases or non-conformance with waste disposal requirements. The inspectors selected containers of stored radioactive material, and assessed for signs of swelling, leakage, and deformation. b. Findings
No findings were identified. .3 Radioactive Waste System Walkdown (02.03) a. Inspection Scope
The inspectors walked down accessible portions of select radioactive waste processing systems to assess whether the current system configuration and operation agreed with the descriptions in the UFSARt, Offsite Dose Calculation Manual, and Process Control Program. The inspectors reviewed administrative and/or physical controls (i.e., drainage and isolation of the system from other systems) to assess whether the equipment that was not in service or was abandoned in place would not contribute to an unmonitored release path and/or affect operating systems or be a source of unnecessary personnel exposure.  The inspectors assessed whether the licensee reviewed the safety significance of
systems and equipment abandoned in place in accordance with 10 CFR 50.59, "Changes, Tests, and Experiments." 
15 Enclosure
The inspectors reviewed the adequacy of changes made to the radioactive waste processing systems since the last inspection.  The inspectors evaluated whether
changes from what is described in the UFSAR were reviewed and documented in accordance with 10 CFR 50.59, as appropriate, and to assess the impact on radiation doses to members of the public. The inspectors selected processes for transferring radioactive waste resin and/or sludge discharges into shipping/disposal containers and assessed whether the waste stream mixing, sampling procedures, and methodology for waste concentration averaging were
consistent with the Process Control Program, and provided representative samples of the waste product for the purposes of waste classification as described in 10 CFR 61.55,
"Waste Classification." 
For those systems that provide tank recirculation, the inspectors evaluated whether the tank recirculation procedures provided sufficient mixing.  The inspectors assessed whether the licensee's Process Control Program correctly described the current methods and procedures for dewatering and waste stabilization (e.g., removal of freestanding liquid). b.

For the waste streams listed above, the inspectors assessed whether the licensee's radiochemical sample analysis results (i.e., "10 CFR Part 61" analysis) were sufficient to support radioactive waste characterization as required by 10 CFR Part 61, "Licensing Requirements for Land Disposal of Radioactive Waste."  The inspectors
evaluated whether the licensee's use of scaling factors and calculations to account
for difficult-to-measure radionuclides was technically sound and based on current 10 CFR Part 61 analyses for the selected radioactive waste streams.
 
16 Enclosure
The inspectors evaluated whether changes to plant operational parameters were taken into account to:  (1) maintain the validity of the waste stream composition data between
the annual or biennial sample analysis update; and (2) assure that waste shipments continued to meet the requirements of 10 CFR Part 61 for the waste streams selected
above.  The inspectors evaluated whether the licensee had established and maintained an adequate Quality Assurance Program to ensure compliance with the waste classification
and characterization requirements of 10 CFR 61.55, "Waste Classification," and 10 CFR 61.56, "Waste Characteristics." b. Findings
No findings were identified. .5 Shipment Preparation (02.05) a. Inspection Scope
The inspectors observed shipment packaging, surveying, labeling, marking, placarding, vehicle checks, emergency instructions, disposal manifest, shipping papers provided to the driver, and licensee verification of shipment readiness.  The inspectors assessed
whether the requirements of applicable transport cask certificate of compliance had been
met.  The inspectors evaluated whether the receiving licensee was authorized to receive
the shipment packages.  The inspectors evaluated whether the licensee's procedures for cask loading and closure procedures were consistent with the vendor's current approved procedures. The inspectors observed radiation workers during the conduct of radioactive waste processing and radioactive material shipment preparation and receipt activities. 
The inspectors assessed whether the shippers were knowledgeable of the shipping
regulations and whether shipping personnel demonstrated adequate skills to accomplish the package preparation requirements for public transport with respect to the following:
* The licensee's response to NRC Bulleti
n 79-19, "Packaging of Low-Level Radioactive Waste for Transport and Burial," dated August 10, 1979; and
* Title 49 CFR Part 172, "Hazardous Materials Table, Special Provisions, Hazardous Materials Communication, Emergency Response Information, Training Requirements, and Security Plans," Subpart H, "Training."  Due to limited opportunities for direct observation, the inspectors reviewed the technical instructions presented to workers during routine training.  The inspectors assessed
whether the licensee's training program provided training to personnel responsible for the conduct of radioactive waste processing and radioactive material shipment preparation activities. b. Findings
No findings were identified.

a. Inspection Scope
This event, which occurred on April 25, 2013, involved an evolution designed to enable the licensee to access and repair a condenser tube leak identified on the Unit 2 main
condenser east waterbox.  An existing procedure was utilized to allow the unit to stay at
power while the affected half of the waterbox was isolated and drained.  However, during
 
the execution of this evolution, the circulating water (CW) system had its isolation boundary challenged by operators while the waterbox manway covers were still open, which resulted in the flooding of the condenser pit, a CW pump trip, and manual scram.  Documents reviewed are listed in the Attachment to this report.  This LER is closed.  This event follow-up review constituted one sample as defined in IP 71153-05. b. Findings
Failure to Follow Procedure Led to Manual Scram with Complications
Introduction:  A self-revealed finding preliminarily determined to be of low-to-moderate safety significance (White) was identified for the licensee's failure to follow procedure LOP-CW-10, "Dewatering the Circulating Water System," Revision 32, on Unit 2. 
Specifically, operators executed the condenser
waterbox dewatering evolution in a manner inconsistent with procedural guidance, resulting in a circulating water pump trip, loss of the normal heat sink, and reactor scram. 
22 Enclosure
Description:  On April 25, 2013, during Unit 2's restart from a recent forced outage, the licensee identified that a condenser tube leak existed, based on chemistry samples, and
a repair was pursued.  Activities were initiated to identify the tube leak in the east waterbox of the main condenser while the unit was at 56 percent power, as allowed by procedure LOP-CW-10, "Dewatering the Circulating Water System," Revision 32. In the pre-job briefing for the waterbox dewatering evolution, operators decided to add a step to the evolution that was inconsistent with the procedure.  Specifically, when the
CW isolation motor-operated valves (2CW007A and C) were electrically closed from the
control room handswitch per LOP-CW-10, equipment operators were then instructed to
manually close the valves further to achieve tighter closure.  This added step to manually seat the isolation valves as a part of the planned activity was a departure from the procedure.
Attachment B of LOP-CW-10, "Waterbox Isolation Valve Adjustment Troubleshooting Guidelines," which was to be used as a contingency in case of rising waterbox water
levels, did contain steps to manually adjust the isolation valves, but also included the
crucial step to verify all waterbox manways had first been closed and tightened prior to
adjusting the valves.  Since the licensee never entered Attachment B, the waterbox
hatches remained open while the valves were manually closed.  These manual valve
manipulations were not executed in accordance with LOP-CW-10. As a result, when the CW inlet isolation valve (2CW007A) was inadvertently over-travelled 1/4-inch past its closed match mark, CW flow rapidly filled up the waterbox
and overflowed the open upper hatches, spilling into the condenser pit.  The 2A and
2B CW pumps automatically tripped when water collecting in the pit reached the high
water level setpoint of 12 inches.  Control room operators then manually scrammed the
reactor. Analysis:  The inspectors determined that the licensee's failure to follow the prescribed steps of procedure LOP-CW-10 was reasonably within the licensee's ability to foresee and correct and should have been prevented, and is therefore considered a performance deficiency warranting a significance determination.  The inspectors used Inspection
Manual Chapter (IMC) 0609 Appendix A, "The Significance Determination Process
(SDP) for Findings At-Power" Exhibit 1, dated June 19, 2012, for the Initiating Events
cornerstone.  The inspectors answered "yes" to the screening question, "Did the finding cause a reactor trip AND the loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable shutdown conditions?"  The loss of a
condenser is cited as an example of such
an event.  A detailed risk evaluation was
required. The Senior Reactor Analysts (SRAs) used the LaSalle Unit 1 SPAR model as a surrogate for the Unit 2 performance deficiency to perform the detailed risk evaluation. 
The SPAR model revision was 8.21.  Several modifications were performed by Idaho National Laboratory to appropriately model plant response to a loss of condenser heat sink event.  In accordance with Risk Assessment of Operational Events Handbook guidance, for findings that cause initiating events to occur, the initiating event that was observed is set
to 1.0 or "True" and the conditional core damage probability is calculated.  The
conditional core damage probability is multiplied by one inverse year (yr-1) to equate this 
23 Enclosure
to a change in core damage frequency for the performance deficiency.  For this finding, the initiating event "Loss of Condenser Heat Sink" was set to 1.0 using the events and
condition assessment module of the Systems Analysis Program for Hands-On Integrated Reliability Evaluations (SAPHIRE), Version 8. The calculated conditional core damage probabili
ty for a loss of condenser heat sink event was 1.6E-6, which represents a finding of low to moderate safety significance (White).  The dominant sequence is a loss of condenser heat sink event with loss of all
decay heat removal due to failure of suppression pool cooling and failure of containment venting.  Late injection after containment failure is also failed.  LaSalle Unit 2 has a Mark II containment.  The SRAs used IMC 0609 Appendix H, "Containment Integrity Significance Determination Process" dated May 6, 2004, to
evaluate the potential risk contribution due to large early release frequency.  The finding was a "Type A" finding" in which the finding has an impact on core damage frequency.  The dominant sequences involved long-term accident sequences that involve failure of
 
containment heat removal that eventually progresses to containment failure.  These sequences do not contribute to large early release frequency because it is assumed that
effective emergency response actions can be taken within the long time frame of the accident sequences. The licensee also performed an analysis of the performance deficiency using the LaSalle probabilistic risk assessment (PRA) model and provided it to the NRC for information.  The analysis used several different methodologies which produced slightly different
results.  The SRAs determined that the licensee analysis was consistent with the NRC
analysis if similar assumptions were applied.  However, the overall conclusion of the
licensee analysis was that this performance deficiency was best represented by a finding
of very low safety significance (Green).  The NRC determined that the NRC evaluation using standard SDP and Risk Assessment of Operational Events Handbook guidance and the modified SPAR model were appropriate tools for the SDP evaluation and the
finding was best characterized as a finding of low to moderate safety significance (White).  The finding had a cross-cutting aspect in the area of human performance, decision-making, because the licensee failed to use conservative assumptions when planning
and executing the dewatering evolution.  Specifically, the incorrect assumption that this evolution performed at-power could be treated the same as when performed during a shutdown condition enabled operators to stray from strict procedure adherence and into
knowledge space (H.1(b)).   
Enforcement:  This finding preliminarily determined to be of low-to-moderate safety significance (White) did not involve a violation of regulatory requirements because the
systems involved were not safety-related and the evolution was not considered an
activity affecting quality.  The event was captured in the licensee's CAP as AR 01506809 and is being documented as FIN 05000374/2013004-01, "Failure to Follow Procedure Led to Manual Scram with Complications."  Corrective actions included various training
activities for operators, procedure revisions, and potential physical enhancements to the CW isolation valves.

.2 (Closed) LER 050002013-001-00:  Pin Hole Leaks Identified in High Pressure Core
Spray Piping
On April 18, 2013, Unit 2 was in Mode 3 following a scram and a loss of offsite power that had occurred on both units the previous day.  Three pin-hole through-wall leaks in
the U2 HPCS minimum flow line piping were discovered.  The leaks were on the outside bend of the first elbow downstream of the minimum flow restricting orifice, and appeared to be leaking a total of approximately 0.5 gallons per minute (gpm) with the HPCS pump not running. Unit 2 HPCS was declared inoperable and, because the HPCS minimum flow line is in direct communication with the suppression pool, primary containment was also declared
inoperable.  The direct cause of the event was a combination of cavitation and
mechanical wear/erosion of the piping wall.  Corrective actions included replacing the leaking pipe elbow, and performing ultrasonic inspections of susceptible piping on both Units.  Also, HPCS operating procedures were reviewed and revised.  Documents reviewed are listed in the Attachment to this report.  This LER is closed. This event follow-up review constituted one sample as defined in IP 71153-05.
 
Findings Inadequate Procedures Led to Pin Hole Leaks in High Pressure Core Spray Piping
Introduction:  A finding of very low safety significance and associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," was self-revealed for the failure to have procedures adequate for the circumstances during long-term operation of the HPCS system on minimum flow.
Description:  On April 17, 2013, following a station dual-unit loss of offsite power, the HPCS system started on both units.  Unit 2 HPCS system ran in minimum flow mode for
about 17 hours and Unit 1 HPCS system ran in minimum flow mode for about 15 hours
before they were secured.  On April 18, 2013, three small holes developed in the  Unit 2 HPCS minimum flow line elbow.  Total leakage was about 0.5 gpm. The licensee determined in the Apparent Cause Evaluation (AR 1503825-08) that these holes were caused by cavitation and other flow related wear.  The licensee's apparent cause for the through-wall leak of the HPCS minimum flow (min-flow) line was
"inconsistent procedural guidance regarding operation in the min-flow mode."  The
inspector reviewed the HPCS operating procedures and agreed with the licensee's
 
assessment.  In response to NRC Bulletin 88-04, "Potential Safety Related Pump Loss," the licensee stated that they would put precautions in operating procedures not to run the pump in min-flow mode for extended periods.  The vendor information available at that time stated that extended operation was anything over 3 hours.  Licensee procedure LOP-HP-04, "Shutdown of High Pressure Core Spray System After An Automatic Initiation," Revision 11, had a precaution statement that, "In order to
minimize pump degradation, consideration should be made to secure the HPCS pump
when extended periods of operation on minimum flow is expected."  In addition, there
was a note in the body of the procedure that says that if the pump is to be run in the min-flow mode for longer than 30 minutes then an additional flow path should be provided by running in the full flow test mode.  However, these warnings do not specify 
25 Enclosure
that the pump cannot be run in min-flow for long periods of time; instead, the procedure only specifies that the pump "should not" be operated in min-flow for long periods of
time.  Finally, LOP-HP-04 neither had any procedural guidance on how to operate in the full flow test mode with a high drywell pressure signal present nor did it reference any other procedure on how to operate the system in this manner.
Analysis:  The inspectors determined that having HPCS operating procedures that were inadequate for the circumstances of running HPCS in the minimum flow mode for
extended periods was contrary to 10 CFR 50, Appendix B, Criterion V, and was a performance deficiency. The finding was determined to be more than minor because the finding was associated
with the Mitigating Systems cornerstone attribute of Procedure Quality and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences.  Specifically, the procedural guidance given to operate the HPCS system was inadequate to prevent long-term operation of the system in the minimum flow mode of operation 
that led to cavitation and flow-induced wear which resulted in 3 pin hole leaks in the 
Unit 2 HPCS min-flow line.  The inspectors determined that the finding could be evaluated in accordance with  IMC 0609, Appendix A, "The Significance Determination for Findings At-Power," dated June 19, 2012, and Appendix H, "Containment Integrity Significance Determination Process," dated May 6, 2004.  The inspectors used Section A of Exhibit 2 of Appendix A,
"Mitigating Systems Screening Questions."  The inspectors answered all four questions
"No" because even with the holes in the minimum flow line the HPCS could still inject and therefore did not lose its safety function.  The inspectors also reviewed IMC 0609, Appendix H, Section 6.0, "Procedure For  Type B Findings."  A Type B finding is one that has no effect on delta-core damage
frequency.  The inspectors entered Table 6.1 and determined that a phase two review was necessary because LaSalle has a Mark II containment and the finding impacted suppression pool integrity.  The inspectors then entered Table 6.2 which stated that if
the leakage from the drywell was less than 100 percent of the drywell volume per day
then the issue screened as Green.  The inspectors determined that leakage from the
drywell to the environment was less than 100 percent per day based on information from IMC 0308, Appendix H, "Technical Basis, Containment Integrity Significance Determination Process (IMC 0609, App H) For Type A and Type B Findings Full Power
and Shutdown Operations," dated May 6, 2004.  Inspection Manual Chapter 0308,
Section 2.2, stated that the hole size that would result in leakage equivalent to greater
than 100 percent of the containment volume per day would have a diameter of greater
that one inch.  A circle around all the holes combined found in the HPCS piping was less
than 0.5 inches in diameter.  Therefore, this issue screens as Green. The inspectors did not identify a cross-cutting aspect associated with this finding. 
 
Enforcement:  Title 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," requires, in part, that activities affecting quality be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and be accomplished in accordance with these instructions, procedures,
or drawings.  Procedure LOP-HP-04, "Shutdown of High Pressure Core Spray System 
26 Enclosure
After an Automatic Initiation," Revision 11, is considered an activity affecting quality by the licensee as well as by the NRC. Contrary to the above, on April 17, 2013, the licensee failed to have procedures of a type appropriate to the circumstances needed to operate and shut down the HPCS system. 
Specifically, the procedural guidance available to the operators allowed them to operate the HPCS system in the min-flow mode for 17 hours on Unit 2 and 15 hours on Unit 1, which resulted in an unisolable leak hole in the Unit 2 HPCS min-flow line (and ultimately in the suppression chamber) and degraded the Unit 1 HPCS min-flow piping.  Because this violation was of very low safety significance and it was entered into the licensee's CAP (as ARs 1503825 and 1530682), this violation is being treated as an
NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy (NCV
05000373/2013004-02; 05000374/2013004-02, Inadequate Procedures Led to Pin Hole
Leaks in High Pressure Core Spray Piping). As corrective actions, the licensee immediately declared the HPCS system and the primary containment inoperable and entered the applicable TS actions.  The affected pipe elbow was then promptly replaced and the systems returned to service. 
Additionally, an extent of condition examination was performed on other potentially
effected sections of piping.  Finally, to prevent recurrence, the licensee revised the effected procedures. .3 (Closed) LER 050002012-001-00:  2B DG Declared Inoperable Due to Excessive Air Start Receiver Blowdown Caused by a Degraded Drain Valve
This event, which occurred on August 31, 2012, involved preventive maintenance that was being performed on the 2B DG 'A' train starting air receiver, which was not intended to cause the system to be inoperable.  While operators were blowing down the air receiver, the pressure decreased below the minimum allowable 165 pounds per square
inch (psig) required for DG operability per TS 3.8.3 Condition D.  The licensee declared
the system out of service and entered the appropriate TS action statement.  Shortly
thereafter, system pressure was restored and the 2B DG was declared operable.  The cause of the event was determined to be a degraded drain valve on the receiver.  The licensee replaced the valve at a later date to prevent recurrence.  No findings were identified.  This LER is closed. This event follow-up review constituted one sample as defined in IP 71153-05 .4 (Closed) LER 050002013-003-00:  Low Pressure Core Spray System Declared Inoperable Due to Faulty Control Switch
This event occurred on April 18, 2013, while Unit 1 was in Mode 3 following a loss of offsite power event and dual unit scram the previous day.  While attempting to raise
Unit 1 reactor water level using the Low Pressure Core Spray (LPCS) system, LPCS
injection motor-operated valve 1 E21-F005 failed to open when its control switch was
held in the "OPEN" position.  The LPCS system was declared inoperable but available, and the appropriate TS action statement was entered, requiring that LPCS be restored to operable status within seven days.
 
27 Enclosure
The cause of the event was determined to be the failure of the control switch due to the buildup of oxidation on the contact surfaces.  All other contacts in the switch were found
to be working normally.  The corrective action was to replace the control switch.  A sample of similar switches has been scheduled to be tested to determine if electrical contact erosion is starting to occur on other switches with similar in-service life installed in similar electrical circuits. This event was also discussed in greater detail and was associated with a non-cited violation previously documented in NRC Special Inspection Report 05000373/2013009;
05000374/2013009.  No additional findings were identified during this LER review.  This LER is closed. This event follow-up review constituted one sample as defined in IP 71153-05. .5 (Discussed) LER 05000373/2012-001-00, 374/2012-001-00:  Secondary Containment Inoperable Due to Interlock Doors Open
As previously described in NRC inspection report 05000373/2013003; 05000374/2013003 02, the inspectors are in the process of reviewing the adequacy of
the licensee's implemented and planned corrective actions in response to the events described in the subject LER.  Since resolution of the associated unresolved item (URI) is necessary to determine if there are any violations of NRC requirements, this LER review will not be closed at this time.  Documents reviewed are listed in the Attachment to this report.  This LER is not closed. This continuation of an event follow-up review did not constitute a completed sample as defined in IP 71153-05. .6 (Discussed) LER 05000373/2013-001-00, 374/2013-001-00:  Secondary Containment Inoperable Due to Interlock Doors Open
As previously described in NRC inspection report 05000373/2013003; 05000374/2013003 02, the inspectors are in the process of reviewing the adequacy of
the licensee's implemented and planned corrective actions in response to the events described in the subject LER.  Since resolution of the associated URI is necessary to determine if there are any violations of NRC requirements, this LER review will not be closed at this time.  Documents reviewed are listed in the Attachment to this report.  This LER is not closed.

  This event occurred on April 22, 2013, while Unit 1 was in Mode 2, Startup.  Reactor pressure was increased to above 150 psig with the RCIC system isolated and inoperable.  This was an action prohibited
by TS and was previously discussed and
documented as a Licensee-Identified Green NCV in NRC Inspection Report
05000373/2013002; 05000374/2013002, Section 4OA7.  No additional findings were 
28 Enclosure
identified.  Documents reviewed are listed in the Attachment to this report.  This LER is closed. This event follow-up review constituted one sample as defined in IP 71153-05. .8 Review of Event Notification EN 49167 Retraction
On July 1, 2013, the licensee made a 10 CFR 50.72 event notification (EN 49167) for the Unit 2 HPCS minimum flow valve pressure switch setpoint found outside of
tolerance.  The setpoint was found at 112.6 psig instead of greater than or equal to
113.2 psig.  At the time of notification, the licensee determined that this was a condition
that could have prevented fulfillment of a safety function needed to mitigate the consequences of an accident.  On August 5, 2013, the licensee determined that premature opening of the HPCS minimum flow valve would not have prevented the
HPCS from fulfilling its safety function since the licensee's emergency core cooling
system loss-of-coolant accident analysis assumed that the HPCS minimum flow valves
is open during an injection.  In addition, the pressure switch in conjunction with the pump discharge flow switch would still provide adequate pump protection during low flow conditions.  The inspectors did not identify any safety-significant issues with the licensee's retraction. Documents reviewed are listed in the Attachment to this report. 
This event follow-up review constituted one sample as defined in IP 71153-05. 4OA6  Management Meetings
