REACTOR SAFETY Initiating Events, Mitigating Systems, Barrier Integrity 1R04.1 Equipment Alignment (IEMA Keystone: Reactor Safety) (71111.04)
- a.
Inspection Scope The inspector performed equipment configuration alignment and general area inspections in the following plant areas:
e Main Control Room and Back Panel Areas
- Unit 1 &2 Reactor Feed Water Pump Rooms
- Unit 1&2 4 KV Buses (safety and non-safety)
- Unit 1&2 High Pressure Coolant Injection (HPCI) Rooms Unit 1&2 Residual Heat Removal Service Water (RHRSW) Pump Vaults
- Unit 1&2 Reactor Building Comer Pump Rooms
- Shutdown Makeup, pump (SSMP) Room
- Unit 1 &2 and Unit 1/2 Emergency Diesel Generator (EDG) Rooms
- Refuel Floor
- b.
Observations and Findings During walk down inspections of plant equipment areas, the inspector verified equipment configuratidn and observed for any material condition deficiencies that could prevent proper equipment operation. Equipment areas were inspected for system leakage, personnel safety hazards, potential interference with system components and controls, fire hazards, water intrusion, and the integrity of system structural supports. The inspector monitored equipment areas for abnormal vibration, odors, sounds, or other conditions that could impact proper equipment operation and plant safety.
On January 7, the inspector while touring the power block, identified high oil levels on the 2A and 2B Standby Liquid Control System (SBLC) pump motors; low oil level on the IA Control Rod Drive pump motor and pump; and some unusual labeling on containment pressure switches. The unusual labeling attached to containment pressure switches stated, "Refer to QCOP 1600-29 before manipulating this valve - primary containment could be violated", then gave the pressure switch number, for example PS 1-1001-90A.
.3
The inspector, through investigation determined that removal or disassembly of the pressure switch could potentially open a direct path from the primary containment to secondary containment. Since mechanical maintenance workers performed maintenance on the wrong equipment 3 days earlier due to misleading labeling on plant equipment, the inspector provided this information to the Shift Manager for resolution.
On January 9, the inspector verified that the SLC pump oil levels were within their normal operating band. The inspector also reviewed IR 865106 which was initiated to correct the valve labeling and on January 12, the inspector received an email from the licensee informing him that new labels had been installed under IR 865106 and that oil had been added to the 1A Control Rod Drive (CRD) pump and motor. The inspector verified on January 14 that the new labels had been installed.
On March 3, the inspector identified a 3 dpm leak from the ceiling above the 1B Core Spray (CS) room. The inspector reported this condition to the Shift Manager who had it investigated and determined that the leak was from a previously identified packing leak from root valve (1-3199-63C) in the D-Heater Bay, located directly above the 1BCore Spray (CS) room.
The previously installed catch container for this leak was no longer capturing the leakage and needed adjustment for proper fluid capture (IR 888642). The leaking valve is scheduled to be repacked during refueling outage QiR20 under Work Order #1204489.
On March 10, the inspector determined from the operations log that in addition to the Unit 2 Station Black Out (SBO) Diesel Generator (DG) being out of service for scheduled maintenance, that the /2 Diesel Generator was inoperable due to a scheduled surveillance run, thus two diesel generators were out of service. The inspector referenced Technical Specification (TS) Limiting Condition for Operation (LCO) 3.8.1, AC Sources-Operating, and determined that if two required diesel generators were out of service that the station would be in a two hour shutdown action statement. The inspector reviewed the Technical Specification LCO Basis for 3.8.1, AC Sources-Operating and found no definition for equipment requirements. The inspector then talked to the Unit 1 Supervisor and found that the SBO DGs are not included in the required DGs per the Technical Specification and therefore not considered as technical specification limiting equipment.

Conclusions There were no significant issues identified during this inspection activity.

1R04.2 Equipment Alignment (IEMA Keystone: Reactor Safety) (71111.04)
(Closed) Open Item 070C-40IR-002: The inspector's verification that the licensee is documenting control rod exercising and maintaining permanent records of activities affecting quality, i.e., Reactor Mode Switch position.
On September 10, 2007 while reviewing the Main Control Room logs, the inspector identified that on September 8, 2007, at 4:07 am, that Unit 1 reached Mode 3 (Hot Shutdown). Thirteen minutes later, at 4:20 am, the mode switch was moved, by procedure, from the SHUTDOWN to the REFUEL position. The mode switch remained in the REFUEL position until September 10, 2007, at 6:40 pm when the unit entered mode 2 for reactor restart. The Mode switch was in the REFUEL position for approximately 62 hours7.175926e-4 days <br />0.0172 hours <br />1.025132e-4 weeks <br />2.3591e-5 months <br /> and 20 minutes with no documented control rod movement.
The inspector reviewed the main control room logs on Monday September 10, and seeing no main control room log entries describing control rod movement, questioned main control room operators regarding the current mode switch position and if any control rod movement was in progress.
The inspector was informed by operations that they had been "stroking rods" and that they were having problems with the Rod Position Indicating System (RPIS) that might require them to move additional control rods for post maintenance (PM) testing. No mention of control rod motion was ever recorded in the Main Control Room log.
The inspector reviewed Exelon corporate procedure OP-AA-111-101, revision 6. OPERATING NARRATIVE LOGS AND RECORDS, to determine the requirements that Exelon required for the level of detail for main control room logs. Exelon procedure OP-AA-11-101, step 4.1.1 states "Maintain records at a level of detail that will allow reconstruction of shift activities by oncoming personnel that do not have the benefit of a face-to-face discussion with the shift." Contrary to this requirement, the main control logs for September 8-10, 2007 made no mention of any control rod movement even though main control room operators stated that they were moving control rods intermittently through out the entire outage.
In response to this issue generated by the inspector, IR # 692880 was initiated.
On September 20 and 21, 2007, the inspector attempted to obtain documentation corroborating the intentional movement of control rods 5
during the Unit 1 outage September 8-10, 2007. The inspector talked to the Control Rod Drive (CRD) System Engineer, the Operations Records Coordinator, and Station Nuclear Engineers looking for verbal and documented evidence of control rod movement. All three personnel thought that control rods had been exercised, but none had any documentation. The CRD System Engineer stated that procedure QCOP 0300-18, rev. 18. CONTROL ROD EXERCISING should have been performed and that she would continue to look for a copy. The inspector was later informed that the completed procedure, QCOP 0300-18, had been inadvertently shredded. The inspector was informed by operations personnel that procedure QCOP 0300-18 has a "life of plant" retention requirement. In response to this issue, IRs # 692865 and #680638 were initiated.
On October 2, 2007, the inspector, along with the NRC Senior Resident Inspector, determined that procedure QCOP 0300-18 on step F.4, directed the operators to place the mode switch in to the REFUEL position per procedure QCOP 0500-06, rev. 7, MOVING THE REACTOR MODE SWITCH OUT OF SHUTDOWN POSITION, but QCOP 0300-18 did not contain a step to return the mode switch to SHUTDOWN per QCOP 0500-
- 06. This procedure shortcoming resulted in the procedure not being capable of maintaining compliance with TS 3.10.2 & 3 and the reactor mode definition. The licensee revised the procedure to reflect the proper compliance with the Technical Specification equipment specification.
The inspector has monitored mode switch position during the last several plant shutdowns and based upon control room performance and their heightened awareness to Technical Specifications 3.10.1 and 3.10.3, the inspector has determined that the licensee is in compliance with Technical
,Specification requirements. This item is considered closed.
1R04.3 Equipment Alignment (IEMA Keystone: Reactor Safety) (71111.04)
- a.
Inspection Scope (Closed) Open Item 080C-1OIR-001: The inspector's verification that procedure QCOP 1300-09 has been revised to remove the dichotomy between procedural steps.
On January 15, 2008, the Unit 1I Reactor Core Isolation Cooling (RCIC)
System controller failed from its automatic control mode to the manual 6
mode. A "Fail Red" light was received on the RCIC control room annunciator panel. RCIC was then declared inoperable and unavailable.
Following discussions between the Shift Manager and the Station Risk Coordinator, the Shift Manager assigned a dedicated operator (if needed) to perform a manual RCIC start, in accordance with QCOP 1300-09 revision 21, RCIC Local Manual Operation. This operator was not assigned to any specific area to remain in, e.g., the RCIC Pump Room; his instructions only specified that he be able to transit from an unspecified location in the plant to the RCIC controls to perform the local startup of RCIC. Assignment of the dedicated operator and availability of RCIC were based upon the capability to get the RCIC System aligned to inject within 30 minutes, per 10CFR50, Appendix R analysis.
The inspector walked through the performance of QCOP 1300-09 in the field and verified that the procedure could be performed within 30 minutes, but with substantial distance between components in the reactor building and the RCIC room, it would be. difficult. The Nuclear Regulatory Commission (NRC) Senior Resident Inspector (SRI) questioned this practice and ultimately determined that RCIC was designed for loss of feedwater transients and thus was necessary to be aligned for injection within approximately 5 minutes.,
From the inspector's walk down, it appeared obvious that the operator would not be able to complete this activity within the 5 minute timeframe and thus RCIC would be unavailable. NUMARC 93-0 1, "Industry Guidelines for Monitoring the Effectiveness of Maintenance at Nuclear Power Plants" stated that credit for a dedicated operator could be given if the function could be promptly restored either by an operator in the control room or a dedicated operator stationed locally for that purpose. Procedural guidance provided in plant procedure WC-AA-101, rev 14, "On-Line Work Control Process" followed the NUMARC document recommendations but was not followed. This resulted in a NRC issued Non-Cited Violation.
In addition to the time issue, the inspector identified several procedure issues that would impede the start-up and/or potentially prevent operation of the RCIC system. Precaution step D.2 of QCOP 1300-09 stated that, "RCIC operation below 400 gpm should be minimized to limit cycling to Turbine Exhaust check valve." ýProcedure step F.5.6.c directed the operator to establish RCIC discharge flow less then 400 gpm. These two steps were in obvious disagreement. QCOP 1300-09 was subsequently revised; revision 23 incorporated the inspector's comments. The inspector considers this item as closed.

1R04.4 Equipment Alignment (IEMA Keystone: Reactor Safety) (71111.04)
- a.
Inspection Scope (Closed) Open Item 08QC-1QIR-003: The inspector performed a follow-up investigation on the design difference in pipe support hangers between Unit 1 and 2 Torus vent lines to verify that Unit 2 met its design requirement.
- b.
Observations and Findings On March 20, while touring the Unit 1 reactor building, the inspector noticed a pipe hanger (for an 18" Torus vent line) oscillating underneath a portion of pipe that it apparently should have been supporting. The inspector noticed a second, newer looking, set of pipe hangers on this line also, but the hanger in question was the same as the one on Unit 2.
The inspector brought this condition to the attention of the licensee's engineering department whose response was that Unit 1 underwent a pipe support modification that added the new stronger hangers because of increased calculated loads, and the old hangers were no longer credited with a support function. Therefore, the lack of support by the hanger in question was not an issue since the support function of the hanger was no longer required.
The inspector then questioned the engineer as to why the Unit 2 supports were not the newer style like those found on Unit 1. The response to the inspector's question was that most likely the calculated piping loads associated with each unit were not the same. IR 752598 was initiated to address this issue and the question and was subsequently closed. The inspector has talked to engineering personnel who have provided prints verifying that the pipe arraignment, though different between the units, was per design and was considered adequate. The inspector considers this item as closed.
1R05.1 Fire Protection (IEMA Keystone: Reactor Safety) (71111.05)
- a.
Inspection Scope The inspector evaluated the licensee's fire protection program for operational status, and material condition and verified the adequacy of:
- Controls for combustibles and ignition sourceý within the plant
'8
" Fire detection and suppression capability
" Material condition of passive fire protection features
- b.
Observations and Findings The inspector performed regular tours of the Quad Cities power block over the quarter and while on tour, verified compliance with the licensee's fire protection program per procedures OP-AA-201-004 rev 8, Fire Prevention for Hot Work, and OP-AA-201-009 rev 8, Control of Transient Combustible Material.
- c.
Conclusions There were no significant issues identified during this inspection activity.
1R06 Flood Protection (IEMA Keystone: Reactor Safety) (71111.06)
- a.
Inspection Scope This inspection will verify that the licensee's flood mitigation plans and equipment are consistent with~the licensee's design requirements and the risk analysis assumptions.
- b.
Observations and Findings On March 3 and 9 the inspector performed walk downs of the Unit 1 and 2 Reactor Building basement and comer rooms to verify that there were no open pathways that could result in flood water migration to multiple areas.
No deficiencies were identified. On March 3 the inspector did identify a leak into the lB Core Spray room from the D-Heater Bay. This deficiency was discussed in section 1R04.1.
- c.
Conclusions There were no significant issues identified during this inspection activity.
IR 1I Licensed Operator Requalification Program (IEMA Keystone: Reactor Safety)(71111.11)
- a.
Inspection Scope 9
The inspector observed licensed operator training in the control room simulator to verify that the facility licensee's requalification program for licensed reactor operators (ROs) and senior reactor operators (SROs) ensured safe power plant operation by adequately evaluating how well the individual operators and crews mastered the training objectives, including training on high-risk (critical) operator actions. Performance of the utility evaluators was also evaluated to verify that they identified all appropriate training issues and potential crew enhancements.
- b.
Observations and Findings On February 19, the inspector observed the training week control room exam in the plant simulator. The exam scenario involved a loss of feedwater flow to the reactor resulting in low reactor vessel level.
Concurrent with this, a loss of 4 KV Bus 14-1 and the Unit 1 emergency diesel generator also occurred.
The scenario continued with high drywell pressure and the need for the operations crew to enter the Emergency Operating Procedures (EOP) for Containment Control and reactor vessel depressurization. All critical tasks were completed by the operating crew and crew communications were generally good except for the position of unit supervisor. Communications from the unit supervisor position was acceptable but in need of improvement.
in addition to the simulator examination, the inspector attended the instructor pre-j ob brief and the post-exam debrief and verified that the licensee identified the communication issue described above. The inspector did not identify any issues with~this activity that would prevent the operating crew from protecting the health and safety of the public.
The inspector observed the new flat panel screens to be installed in the control room. The operators did not look at these screens and on questioning in the post-exam debrief, the inspector was informed that the operators had not yet been trained on those screens and therefore were not expected to use them.
- c.
Conclusions There were no significant issues identified during this inspection activity.
1R12 Maintenance Effectiveness (IEMA Keystone: Reactor Safety) (71111.12) 10
- a.
Inspection Scope The inspector evaluated the licensee Maintenance Rule (MR) Program to verify that Safety System or Component (SSC) performance or condition problems were identified and corrected.
- b.
Observations and Findings On January 21, the inspector reviewed Incident Reports (IR) 867347 and 867351 which described a problem with valve packing leaks as evidenced by boron crystals on the valve stems of both Unit 2 Standby Liquid Control (SBLC) system pump suction valves. The inspector walked down the SBLC systems and determined that the Unit 1 SBLC system pump suction valves had packing leaks similar to those of Unit 2. IRs 873445, 873449, and 869809 were initiated based on the inspector's observation. In this case, plant personnel identified a deficiency on Unit 2 SBLC but did not look at Unit 1 SBLC for an extent of condition verification of system packing leaks on identical components.
On January 29, the inspector performed a search and review of IRs that were initiated on the SBLC system from January 29, 2009 back to January 1, 2008, to verify that all of the issues with this system were being captured and resolved. From this review, fifty-six IRs were identified and categorized. The inspector was satisfied that the issues for the SBLC system were being identified and resolution of those issues performed in a timely manner.
The inspector reviewed the out of service hours used in the Maintenance Rule (MR) and verified that while those hours were higher then the inspector anticipated (224 hours0.00259 days <br />0.0622 hours <br />3.703704e-4 weeks <br />8.5232e-5 months <br /> per train per rolling 24 month period), they were the same hours used in the plant Probabilistic Risk Assessment (PRA). Because of this, the inspector was satisfied with the out of service hours.
- c.
Conclusions There were no significant issues identified during this inspection activity.
1R13 Maintenance Risk Assessment & Emergent Work Evaluation (IEMA Keystone: Reactor Safety) (71111.13) 11
- a.
Inspection Scope The inspector monitored the licensee's on-line risk assessment on a continual basis.
- b.
Observations and Findings The inspector monitored the on-duty shift activities concerning risk assessment practices during scheduled plant maintenance and emergent work activities. The on-shift supervisors updated the on-line risk assessments to their appropriate levels when plant conditions warranted and it was their practice to consult the Station Risk Coordinator in the event they encountered an equipment configuration not previously evaluated.
On January 20, the Unit 1 Reactor Core Isolation Cooling System (RCIC) was out of service due to scheduled maintenance. The inspector walked down the major pieces of protected equipment; the Unit 1 High Pressure Coolant Injection System (HPCI) and the Safe Shutdown Makeup Pump (SSMP). The inspector verified that these two systems were aligned to standby status per QCOP 2900-01 rev.27, Safe Shutdown Makeup Pump System Preparation for Standby Operation; and QCOP 2300-01 rev. 50, HPCI Preparation for Standby Operation.
- c.
Conclusions There were no significant issues, identified during this inspection activity.
IR15 Operability Evaluation (IEMA Keystone: Reactor Safely) (71111.15)
- a.
Inspection Scope The inspector reviewed the open operability evaluations for the plant.
- b.
Observations and Findings The inspector reviewed the following open operability evaluation:
749118/749132; HPCI Restricting Orifices gaskets below rated
- pressure,
- 782575; Environmental Qualifications of equipment following a Main Steam Line Break 12
- 822508/824347; DC Battery non-conformance of undersized plate spacers.
No issues or comments were generated.
- c.
Conclusions There were no significant issues identified during this inspection activity.
1R19 Post Maintenance Testing (IEMA Keystone: Reactor Safety) (71111.19)
- a.
Inspection Scope The inspector verified that post-maintenance test procedures and test activities were adequate to verify system operability, and functional capability.
- b.
Observations and Findings Over the inspection period, the inspector reviewed completed Post Maintenance Test (PMT) procedures to verify that repaired systems were made operable. Where IRs were initiated, the inspector verified-that the IR condition did not prevent the system from being declared operable.

On January 22, the inspector observed the performance of portions of Valve Operator Test Evaluation System (VOTES) of RCIC Torus Suction Valve 1-1301-25. On January 28, the inspector reviewed the completed datasheets from that testing. No issues were identified.
On February 18, the inspector reviewed the PMT for the Unit 2 High Pressure Coolant Injection (HPCI) System speed changer; QCOS 2300-23 rev 6, HPCI Motor Speed Changer Timing Test. In this PMT, the inspector identified that on step F. 1, that the test performer was instructed to record stroke times to 1/10o of a second. The performer circled the step number of this step indicating that he read and understood the step. On procedure step H.2, the motor speed changer start time was recorded as "15". This was not in accordance with step F. 1 and with acceptance criteria of < 15 seconds; there was a question of whether the acceptance criteria was in fact met.
The inspector discussed this issue with the Shift Operations Superintendent who initiated IR 885737 to document the issue and investigate it. The Shift Operations Superintendent talked to the personnel that performed the surveillance and determined that the stroke time was 15.0 seconds, thus the acceptance criteria was met. The Shift Operations Superintendent also decided to revise QCOS 2300-23 to make it clearer that the stroke time needed to be recorded to the nearest 1/10th of a second by revising the acceptance criteria from < 15 seconds to < 15.0 seconds.

1EP6.1 Drill Evaluation (IEMA Keystone: Emergency Preparedness & Planning)
(71114.06)
- a.
Inspection Scope The inspector evaluated the drill performance of the Technical Support Center (TSC).
- b.
Observations and Findings On March 12, the inspector observed the Team "B" TSC drill performance as part of their emergency preparedness performance indicator (PI). The 15
drill performance was not as polished as the inspector has observed in previous drills and the drill scenario was not free of issues. The inspector was not able to attend the post-exercise critique due to a conflict with other inspection activities, but did talk to the Nuclear Regulatory Commission (NRC) inspector who did attend and was informed that drill deficiencies were identified. The inspector did make several observations on the drill and these observations were forwarded to the licensee's emergency preparedness group. These observations included:
e During an early TSC brief, 3 priorities were discussed by the team, but only one was listed on the station priority board.
e When EAL FA1 was declared due to a leak that raised drywell pressure, EAL MU7 was not included or discussed as a concurrent EAL. The scenario also did not include the EAL, but the scenario acknowledged it should have.
9 The TSC briefs did not contain a status of the top priorities. With the TSC managing repair and recovery efforts in the field; a discussion of the status of those efforts was needed.
These issues were discussed with the TSC scenario development and evaluation team.
- c.
Conclusions There were no significant issues identified during this inspection activity and several inspector observations.
1EP6.2 Drill Evaluation (IEMA Keystone: Emergency Preparedness & Planning)
(71114.06)
- a.
Inspection Scope The inspector questioned if the Quad Cities reactors should have simulated being shutdown, during the March 12, 2009 TSC drill, following an earthquake that exceeded the Operating Basis Earthquake (OBE).
- b.
Observations and Findings As part of the March 12, 2009 drill scenario, a simulated earthquake magnitude of 0.15g occurred. This was above the OBE of limit of 0.12g, but was less then the Safe Shutdown Earthquake (SSE) limit of 0.24g. The 16
inspector observed that following the earthquake in-excess of the OBE, there was no discussion regarding shutting down either reactor.
The inspector reviewed:
1 OCFR1 00 Appendix A, Seismic and Geologic Siting Criteria for Nuclear Power Plants 0
10CFR50 Appendix S, Earthquake Engineering Criteria for Nuclear Power Plants
- Regulatory Guide 1.29, rev 3, 1978, Seismic Design Classification

- NUREG-0800, Standard Review Plan, Seismic Classification
- Quad Cities UFSAR Section 3.7, Seismic Design
- QCOA 0010-09 rev 10, Earthquake Following a review of the above documents, it appeared to be a requirement to shutdown a nuclear power plant where its' OBE has been exceeded. The Quad Cities UFSAR, section 3.7.4 did not make any statements about performing a plant shutdown, upon exceeding an OBE, but instead stated that if an earthquake occurred with a magnitude between the OBE and Design Basis Earthquake (the same as SSE) that "a thorough visual inspection of plant areas and instrumentation should be made to check for any abnormalities. If conditions were found to be normal, plant operation would be continued or resumed". Plant procedure QCOA 0010-09, rev 10 contained instructions to inspect for damage, but no steps were provided for response actions if damage was found or any conditions to shutdown both reactors upon exceeding an OBE earthquake per 10CFR100 Appendix A. The licensee has initiated IR 894959 to investigate and resolve this issue.
- c.
Conclusions The inspector will review the outcome of IR 894959 and its impact on Quad Cities procedure QCOA 0010-09, the UFSAR section 3.7.4, and any other impacted documents. This is considered an inspector Open Item

2PS Public Radiation Safety 2PS 1 Environmental MonitoringProgram and Radioactive Material Control Program (IEMA Keystone: Public Radiation Safety 2515A, 71122.01)
- a.
Inspection Scope The inspector reviewed the results from the last set of 54 Tritium well samples, and liquid and gaseous radwaste releases.
- b.
Observations and Findings On March 12th, the inspector received the latest well sample results from the 54 Tritium sample wells. The samples were taken March 6 and 9th.
The groundwater sampling program was intended to monitor the existing plume of tritium (from previous sub-surface piping leaks that were identified and repaired) as it traversed the owner controlled area. Sampling was also designed to provide early warning of any new radioactive leakage.
Samples are taken monthly with a minimum detectable level for Tritium established at 200 Pico Curies per liter (pCi/L).
Currently the licensee has concluded that there are no known active Tritium leaks and the well sample data corroborates that conclusion. The latest well sample data indicates that Tritium activity has stabilized overall with concentration levels in most sample wells below those of a year ago.
The few sample wells that are higher are attributed to the plume moving toward the southwest, as expected.
There were no liquid radwaste releases to the Mississippi River this quarter.
19
The inspector reviewed Main Chimney isotropic data for the period January 27 to February 3, 2009 and found that all isotopics were below the permitted levels.
- c.
Conclusions The inspector will continue to follow tritium related issues as they pertain to well sample results. There were no issues of significance identified during this inspection activity.

The inspection was performed to validate the integrity of the radioactive gaseous and liquid effluent release program and to ensure that the licensee's surveys and controls were adequate to prevent the inadvertent release of uncontrolled radioactive contaminants into the public domain.
- b.
Observations and Findings On March 1 2 th, the Illinois. Environmental Protection Agency (IEPA) visited the Quad Cities Station for their quarterly joint inspection with IEMA. Since the previous IEPA visit on November 18, 2008, little has changed with ground water-related Tritium activity.
A review of the licensee's IRs for the quarter regarding facility REMP sampling issues contained nothing noteworthy.
- c.
Conclusions There were no significant.issues identified during this inspection activity.

40A2.2 Identification and Resolution of Problems: (IEMA Keystone: ALL)
(71152)
- a.
Inspection Scope The inspector reviewed IR 884908 for compliance with NRC regulations and plant operations.
- b.
Observations and Findings On March 4 the inspector reviewed IR 884908, which states that Feedwater, Reactor Recirculation, and Digital Electro-Hydraulic Control (DEHC) systems are all connected into the Quad Cities Local Area 22
Network (LAN). This information was contrary to that provided to the NRC Senior Inspector and the IEMA inspector in March of 2008, following the cyber-security event at Browns Ferry.
At the time the IR was initiated, there were no NRC regulations governing connections between site LAN and digital control circuitry; however the installed wired condition was different from that described to the site inspectors from the previous year.
The inspector determined that the offending connection was for a keyboard, video, mouse switch (KVM). A KVM switch would allow an individual to control more then one computer from a single keyboard/monitor/mouse from anywhere if they had electronic access to the KVM switch. The three digital control system computers were not physically connected to the Quad Cities LAN such that files could be transferred between them. The installed configuration would allow an individual with access to the KVM switch, access to Feedwater and Reactor Recirculation System data, but no control functions. The installed KVM switch configuration had the potential to allow an individual to take control of the DEHC system. The impact of the KVM switch connected to the DEHC system was not easily understood and engineering was assigned to determine if the DEHC system could be controlled through this KVM switch.
- c.
Conclusions The inspector will follow the investigation into the impact on the DEHC system from the KVM switch. This is considered an inspector Open Item
[09QC-1QIR-003].
40A2.3 Identification and Resolution of Problems (IEMA Keystone: Other Activities) (IP 71152)
- a.
Inspection Scope (Closed) Open Item 050C-30IR-002 Resolution of issues involving the Main Steam Safety Valve set point acceptance criteria.
Following discussions with the Dresden IEMA RI in 2005, the inspector reviewed licensee documents including the historical data pertaining to main steam safety valve testing at Quad Cities Station. The inspector monitored the status of the licensee's activities following an NRC finding and subsequent Non-cited violation concerning the safety valves. The 23
inspector worked with the Dresden IEMA Resident Inspector (RI) to provide main steam safety valve failure data in support of his investigation into the related issues.
In 2005, the Quad Cities Station Resident NRC Inspectors had conducted a related inspection, identified a green finding and issued a Non-Cited Violation, NCV 05000254/5005003-07, due to the failure of three main steam safety valves to actuate within plus or minus one percent of the valve's nameplate value during as-found testing as required by the station's Technical Specifications. The-licensee's corrective actions included installing new main steam safety valves, submitting the Quad Cities specific information to the NRC and initiating a license amendment to change the main steam safety valve operating tolerance from +/- 1% to +/-
3%.
The inspector reviewed the Technical Specification manual and determined that Technical Specification 3.4.3 was revised in November 2007. The inspector considers this item as closed.
