SUBJECT: JOSEPH M. FARLEY NUCLEAR PLANT - NRC INTEGRATED INSPECTION REPORT 05000348/2010004 AND 05000364/2010004

Dear Mr. Johnson:

On September 30, 2010, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Joseph M. Farley Nuclear Plant, Units 1 and 2. The enclosed inspection report documents the inspection results, which were discussed on October 21, 2010, with members of your staff. The inspection examined activities conducted under your license as they relate to safety and compliance with the Commission's rules and regulations, and with the conditions of your license. The NRC reviewed selected procedures and records, observed activities, and interviewed personnel. The report documents one self-revealing finding of very low safety significance (Green) which was determined to involve a violation of NRC requirements and one NRC identified Severity Level IV violation and associated finding. Additionally, one licensee-identified violation (LIV), which was determined to be of very low safety significance, is listed in this report. However, because of the very low safety significance and categorization at Severity Level IV and because they were entered into your corrective action program (CAP), the NRC is treating these violations as non-cited violations (NCVs) consistent with the NRC's Enforcement Policy. If you contest any NCV, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the Nuclear Regulatory Commission, ATTN.: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, United States Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC Resident Inspector at Joseph M. Farley Nuclear Plant. In addition, if you disagree with the cross-cutting aspect assigned to any finding 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, RII, and the NRC Senior Resident Inspector at Farley Nuclear Plant.

SUMMARY OF FINDINGS

IR 05000348/2010004 and 05000364/2010004; 07/01/2010 - 09/30/2010; Joseph M. Farley Nuclear Plant, Units 1 and 2; Identification and Resolution of Problems, Event Followup.

The report covered a three-month period of inspection by the resident inspectors, a senior operations engineer and an operations engineer. One NRC-identified Severity Level IV NCV and one self-revealing NCV with very low safety significance (Green) were identified. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, ASignificance Determination Process@ (SDP). Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The cross-cutting aspect was determined using IMC 0310, "Components Within The Cross-Cutting Areas." The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, AReactor Oversight Process,@ Revision 4, dated December 2006.

Cornerstone: Mitigating Systems

  • SL IV. An NRC identified violation of 10 CFR 21.21, Notification of failure to comply or existence of a defect and its evaluation, was identified for an inadequate procedure, resulting in the licensees' untimely reporting of a substantial safety hazard. Specifically, the licensees' station procedure FNP-0-AP-62, Evaluation of Defects and Non-compliances Potentially Reportable Under 10CFR21, failed to identify the appropriate timeliness aspect required by 10 CFR 21.21(a), and allowed the term "discovery" to be the date of the Plant Review Board (PRB) approval, regardless of the date of discovery of the deviation. This resulted in a substantial safety hazard being reported approximately 260 days after the deviation was identified. The NRC received the Part 21 report on July 6, 2010 (approximately 260 days after discovery of the deviation). The inspectors determined the inadequate procedure allowing untimely reporting of substantial safety hazards was a performance deficiency. This finding was more than minor because if the procedure was left uncorrected, a more serious safety concern could occur. Specifically, failure to evaluate deviations and to perform notifications within the specified time frame, 60 days, does not allow for timely evaluation of other components that could be subject to the deviation. Because this issue affected a potential reporting requirement and the NRC's ability to perform its regulatory function, it was evaluated using the traditional enforcement process. Consistent with the guidance of the NRC Enforcement Policy, this violation was categorized at Severity Level IV NCV. This finding was assigned a cross-cutting aspect in the CAP component of the PI&R area in that problems should be thoroughly evaluated such that the resolutions address causes and extent of conditions, as necessary. This includes properly classifying, prioritizing, and evaluating for operability and reportability conditions adverse to quality. Specifically, the licensee was untimely in evaluating and reporting the substantial safety hazard (P.1(c)). (Section 4OA2.2)
Green.

A self-revealing NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified for the licensees' failure to modify surveillance test procedure FNP-2-STP-40.0, Safety Injection with Loss of Off-site Power (LOSP) Test. Following implementation of a modification to the LOSP/Safety Injection (SI) sequencer on both units, the licensee failed to update FNP-2-STP-40.0, resulting in an inadequate procedure. The procedure failed to address placing the Test Trip Override Switch in its "OFF" position during restoration steps. This resulted in an unplanned power interruption to the 2F electrical bus from its only source of power during the test conducted on April 30, 2010, and subsequent re-loading of safety-related loads by the LOSP/SI sequencer, B2F. Following the unplanned power interruption, the licensee implemented a temporary procedure change and promptly restored plant components to required conditions for the current plant mode of operation. The licensee entered the event in its corrective action program (CAP) as CR 2010105854. The finding is more than minor because it adversely affected the procedure quality attribute of the Mitigating Systems (MS) cornerstone objective of ensuring the availability, reliability, and capability of systems responding to initiating events to prevent undesirable consequences (i.e. core damage). Specifically, this finding affected the Unit 2 Train 'A'

4160 volt safety-related 2F electrical bus's ability to provide power to engineered safeguards feature components. Because the unit was in Mode 6, with greater than 23 feet of water above the reactor vessel, the significance of this finding was assessed using the Phase 1 screening worksheets of Attachment 4 and Appendix G, Attachment 1, Checklist 4 of IMC 0609, SDP. The inspectors determined this finding was of very low safety significance (Green), because it did not increase the likelihood of a loss of reactor coolant system (RCS) inventory or degrade the licensees' ability to terminate a leak path or add to RCS inventory. This finding was assigned a cross-cutting aspect in the resources component of the Human Performance area because complete, accurate, and up-to-date procedures were not provided (H.2(c)). (Section 4OA3.2) Violations of very low safety significance, identified by the licensee, have been reviewed by the NRC. Corrective actions taken or planned by the licensee have been entered into the licensees' CAP. These violation and corrective action tracking numbers are listed in Section 4OA7 of this report.

REPORT DETAILS

Summary of Plant Status Unit 1 started the report period at 100 percent Rated Thermal Power (RTP). The unit remained at or near 100 percent RTP until July 4, 2010, when power was reduced to 76 percent RTP due to a step increase in main turbine number nine bearing vibrations. The unit was returned to 100 percent RTP on July 6, 2010. The unit was ramped to 60 percent RTP on July 12, 2010, due to a trip of the 1A steam generator (SG) feed pump resulting from a trip of its oil pump. The licensee repaired the failed breaker for the tripped oil pump and returned the unit to 100 percent RTP on July 14, 2010. The unit remained at or near 100 percent RTP until September 17, 2010, when the unit entered a RCS temperature coastdown for the upcoming refueling outage (RFO). The unit ended the inspection period at approximately 89 percent RTP. Unit 2 started the report period at 100 percent RTP and remained at or near 100 percent RTP for the remainder of the inspection period.

  • CR 2010100931, Excessive leakage of the containment main purge valve (Q1P13V283)

b. Findings

.1 Failure of Containment Isolation Valve to Provide Proper Indication for its Containment Isolation Function

Introduction An issue of concern revealed itself regarding the licensees' corrective actions associated with dual position indication of containment isolation valve Q1P16MOV3134, SW from RCP Motor Air Coolers. During minor design modifications, the licensee failed to adjust the torque switch setting to provide adequate margin between the torque switch setting and the limit switch setting of the Limitorque motor- operated actuator.

Description On August 14, 2010, Q1P16MOV3134 failed to indicate 'closed' during a normal quarterly surveillance test. The valve continued to have dual position indication, and thus the ability of this valve to perform its containment isolation function, was in question. The licensee entered technical specification (TS) 3.6.3 and closed another isolation valve to restore the function as required. This action resulted in a cooling source to containment air temperature being removed. During the afternoon hours of August 14, 2010, the Unit 1 containment average temperature exceeded its TS limit of 120 degrees F. TS 3.6.5 required the licensee to reduce average temperature below 120 degrees F within eight hours, or be in Mode 3 within six hours and in Mode 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The license requested enforcement discretion on August 15, 2010, to maintain Unit 1 in Mode 1. Discretion was verbally granted by the NRC on August 15, 2010. The NRC determined that the requested enforcement discretion was necessary to avoid unnecessary transients as a result of compliance with the license condition and, thus, minimize potential safety consequences and operational risks.

Q1P16MOV3134 is a six-inch Enertech butterfly valve operated by a Limitorque motor- operated actuator. Each unit has three Enertech butterfly valves in the supply and return lines of SW from the RCP motor air coolers. Two of these valves provide a containment isolation function upon an engineered safeguards function (ESF) actuation. In 2004 and again in 2005, failures occurred where the Unit 2 valves had dual position indication after a demanded position during surveillance testing. In 2007, the licensee recognized the need to make these valves position limit switch seated, instead of torque switch seated, to correct the dual position indication problem. The licensee implemented minor design changes on all six valves to accomplish this corrective action. The licensee failed to recognize the torque switch settings needed to be increased to provide a margin between the limit switch seating value and the torque switch seating value. In 2008 and 2009, the licensee again experienced instances of dual position indication on these valves. In July 2009, the licensee created work orders to adjust the torque switch settings to ensure an appropriate limit to minimizing the potential for dual indication-type closing stroke results. Three of these work orders have been completed, and the remaining three are scheduled to occur in the future.

The inspectors did not identify an immediate safety concern for this issue because the licensee modified the actuation circuitry of Q1P16MOV3134 to remove the torque switch. The licensee has the ability to perform this same temporary modification to the other two remaining valves as well. Additionally, the licensee plans to perform the scheduled work order on Q1P16MOV3134 and Q1P16MOV3135 during the upcoming RFO in October 2010 to properly adjust the torque switch settings.

The inspectors determined in order to determine if a performance deficiency exists and disposition this issue of concern, additional inspection would be required to better understand: 1) the exact cause of the dual indications; 2) the extent of condition associated with this issue supported by review of the licensee CAP and associated work orders; and 3) the licensee planned corrective actions. This issue of concern was identified as unresolved item (URI)05000348/2010004-01, Failure of Containment Isolation Valve to Provide Proper Indication for its Containment Isolation Function.

.2 Failure to Deactivate Containment Isolation Valve

Additionally, one LIV was identified and is documented in section 4OA7.

4OA2 Identification and Resolution of Problems

.1 Daily CR Reviews

As required by Inspection Procedure 71152, Identification and Resolution of Problems, and in order to help identify repetitive equipment failures or specific human performance issues for follow-up, the NRC performed a daily screening of items entered into the licensees' CAP. This review was accomplished by reviewing hard copies of CRs, attending daily screening meetings and accessing the licensees' computerized database.

.2 Selected Issue Follow-up Inspection

a. Inspection Scope

In addition to the routine review, the inspectors selected the issue listed below for a more in-depth review. The inspectors considered the following during the review of the licensees' actions: (1) complete and accurate identification of the problem in a timely manner; (2) evaluation and disposition of operability/reportability issues; (3) consideration of extent of condition, generic implications, common cause and previous occurrences; (4) classification and prioritization of the problem resolution; (5) identification of root and contributing causes of the problem; (6) identification of CRs and (7) completion of corrective actions in a timely manner. The inspectors reviewed the licensees' procedures governing the 10 CFR 21 process, and interviewed station personnel about their duties associated with the above process.

  • CR 2010107145, Request a Part 21 review by Licensing of the Unit 1 and Unit 2 TDAFW pump UPS capacitors manufactured by Ronken Industries

b. Findings

Introduction The NRC inspectors identified a Severity Level IV noncited violation of 10 CFR Part 21.21, "Notification of failure to comply or existence of a defect and its evaluation" for the licensee inadequate procedures which resulted in the licensee's untimely reporting of a substantial safety hazard. Specifically, licensee's station procedure FNP-0-AP-62, Evaluation of Defects and Noncompliances Potentially Reportable Under 10CFR21, failed to identify the appropriate timeliness aspect required by 10 CFR 21.21(a) and inappropriately allowed the term "discovery" to be the date of the Plant Review Board (PRB) approval, regardless of the date of discovery of the deviation. 10CFR21.21.3 defines "discovery" as the completion of the documentation first identifying the existence of a deviation or failure to comply. Description On or about October 16, 2009, the licensee received a failure analysis report from Exelon Power Labs related to an oil-filled capacitor installed in the turbine driven auxiliary feedwater (TDAFW) pump uninterruptable power supply (UPS) on both units. The report concluded the capacitor failed due to a manufacturing defect in which the internal spot-welded connection points on the capacitors were inadequate. These connection points resulted in poor (i.e. high resistance) connections culminating in internal arcing action at several of the connection points. In January, 2010, the NRC inspectors reviewed this report and inquired as to any evaluation performed by the licensee related to 10 CFR Part 21. The inspectors were informed that no evaluation had been completed. On March 30, 2010, the NRC inspectors again inquired as to any evaluation performed by the licensee related to 10 CFR Part 21. Again, the inspectors were informed that no evaluation had been completed. On May 25, 2010, the licensee entered condition report (CR) 2010107145 into its CAP requesting a Part 21 review by corporate licensing for the TDAFW pump UPS capacitors manufactured by Ronken Industries. The licensee discussed the information contained in the Exelon Power Lab report with the dedicating entity, Trentec, Business Unit of Curtiss Wright Flow Control Company. Trentec submitted a Part 21 report on July 6, 2010 (approximately 260 days after discovery of the deviation). The report identified eight defective 70 micro Farad-660v oil filled capacitors manufactured in 2006 (06-06 date code). All eight capacitors had been shipped to the Farley Nuclear Plant. The licensee generated WOs and have replaced capacitors in the TDAFW pump UPS. The inspectors reviewed station procedure FNP-0-AP-62, revision 9.0. The procedure requires any person discovering a defect or deviation indicative of a safety hazard to notify their group supervision. The group supervisor will then contact the Performance Analysis Supervisor (or designee). The inspectors interviewed station personnel and discovered this did not occur until prompted by the NRC inspectors. FNP-0-AP-62 further states that upon notification of a potentially reportable item, the Performance Analysis Supervisor shall determine the following: 1) does a potential defect exist; 2) has the item containing the potential defect been accepted for use by the Farley Nuclear Plant; and 3) does a potential substantial safety hazard exist. If all of the above three questions are answered in the affirmative, a report shall be prepared and presented to the Plant Review Board. FNP-0-AP-62 further states, "discovery shall be the date of the Plant Review Board approval of the report" mentioned above. The inspectors also discovered an alternate method to determine 10 CFR 21 reportability in FNP-0-AP-62; a request may be made that Corporate Farley Support evaluate the item.

In this case, discovery is the date as defined in Southern Nuclear Company Corporate Procedure. The inspectors did not discover the licensee's use of this alternate method until after the March 30, 2010 inquiry by the NRC inspectors. The inspectors determined that as written, individuals were allowed to take the amount of time deemed sufficient, and the reporting clock did not start until the discovery date as defined in FNP-0-AP-62.

The inspectors determined this failed to meet the intent of 10 CFR Part 21.21(a) which states in part defects and failures to comply associated with substantial safety hazards should be identified as soon as practicable, and, in all cases with 60 days of discovery of a deviation.

  • Analysis The inspectors determined the inadequate procedure, which allowed untimely reporting of substantial safety hazards, was a performance deficiency. This finding was more than minor because if the procedure was left uncorrected, a more serious safety concern could occur. Specifically, failure to evaluate deviations and to perform notifications within the specified time frame, 60 days, does not allow for timely evaluation of other components in the industry that could be subject to the deviation. Because this issue affected a potential reporting requirement and the NRC's ability to perform its regulatory function, it was evaluated with the traditional enforcement process. Consistent with the guidance of the NRC Enforcement Policy, this violation was categorized at Severity Level IV NCV. Consistent with the guidance of MC 0612, the inspectors evaluated the performance deficiency in accordance with the reactor oversight process and performed a Phase 1 SDP analysis using the screening worksheets of Attachment 4 of MC 0609. The inspectors determined the finding to be of very low safety significance because the finding did not result in loss of safety function of a single train for longer than it's allowed technical specification outage time and was not risk significant due to seismic, flooding or severe weather concerns. This finding was assigned a cross-cutting aspect in the CAP component of the PI&R area in that problems should be thoroughly evaluated such that the resolutions address causes and extent of conditions, as necessary. This includes properly classifying, prioritizing, and evaluating for operability and reportability conditions adverse to quality. Specifically, the licensee was untimely in evaluating and reporting the substantial safety hazard. P.1(c) Enforcement 10 CFR 21.21(a), "Notification of failure to comply or existence of a defect and its evaluation" states, in part, that each individual or corporation subject to the regulations in this part shall adopt appropriate procedures to evaluate deviations and failures to comply. These defects and failures to comply associated with substantial safety hazards should be identified as soon as practicable, and, in all cases with 60 days of discovery. Contrary to the above, the licensees' procedural guidance in FNP-0-AP-62 was inadequate in that individuals were allowed to take the amount of time deemed sufficient, and the reporting clock did not start until the completion of documentation to the Plant Review Board. This resulted in the evaluation of the manufacturing defect in the 70 micro Farad capacitor taking approximately 260 days. This is a Severity Level IV violation because the finding impacted the regulatory process and is consistent with the NRC Enforcement Policy. Because this finding was of very low safety significance and has been entered into the corrective action program as CR 2010110840, this violation is being treated as a noncited violation, consistent with the NRC Enforcement Policy: SL IV 05000348/364/2010004-02, "Failure to Adopt Appropriate Procedures to Evaluate Deviations and Failures to Comply with 10 CFR 21 Evaluations."

Two Auxiliary Feedwater Pumps Inoperable

a. Inspection Scope

On February 2, 2010, at 4:15 p.m., the Unit 1 TDAFWP was declared inoperable due to high temperature identified on an electrical cable in the TDAFW UPS. The cable high temperature condition was identified by the licensee during performance of a scheduled thermography scan of the UPS cabinet for preventative maintenance. Because the Train 'B' EDG had previously been removed from service for scheduled maintenance, the Train 'B' MDAFWP was also declared inoperable at 8:15 p.m. with the redundant TDAFW pump in an inoperable status. The concurrent inoperability of the TDAFW and Train 'B' MDAFWP was determined by the licensee to represent a condition that could have prevented the fulfillment of a safety function because two out of three trains of AFW are required to meet flow requirements for the limiting design basis accident. The licensee completed repairs to the electrical cable on the TDAFWP UPS at 10:16 p.m. on February 2, 2010, restoring the safety function when the TDAFWP and MDAFWP were returned to operable status. On April 2, 2010, the licensee submitted Unit 1 Licensee Event Report (LER) 2010-002-00 to the NRC regarding the event. The licensee performed additional analysis of the high temperature condition following completion of repairs and determined that the TDAFWP UPS function would not have been adversely affected. The licensee revised the LER on August 20, 2010 to document the post event analysis. The inspectors reviewed the original and revised LERs. The licensee documented the condition in CR 2010101183. This LER is closed.

Unplanned LOSP During SI with LOSP Testing

a. Inspection Scope

On April 30, 2010, Farley Nuclear Plant Unit 2 experienced an unplanned LOSP on the Train 'A' 4160 volt safety-related 2F electrical bus. The licensee previously performed the testing portion of FNP-2-STP-40.0, Safety Injection with LOSP Test, to verify operability of the B2F LOSP/SI sequencer. The licensee was performing the restoration steps of this procedure when the unplanned LOSP occurred. The inspectors reviewed the LER, the licensees' cause determination and licensee planned and completed corrective actions. The inspectors interviewed station personnel to gain understanding of the licensee activities related to the event. The inspectors reviewed applicable procedures related to the event.

b. Findings

Introduction A Green self-revealing NCV of 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified for an inadequate procedure resulting in an unplanned LOSP on the Unit 2 Train 'A' 4160 volt safety-related electrical bus 2F. The licensees' failure to place the Test Trip Override Switch in its "off" position during restoration steps of the test procedure resulted in power interruption to electrical bus 2F from its only source of power during the test, and the subsequent re-loading of safety-related loads by the LOSP/SI sequencer B2F. Description The licensee implemented a design change to the emergency LOSP/SI sequencers on both units to address their inoperability during surveillance testing of the EDGs. The design change provided a circuit opening the EDG output breaker if the EDG was running parallel to the safety-related 4160 volt bus, and an LOSP occurred. This allowed reloading of the EDGs in a controlled manner, which would not have previously occurred. The licensee started implementation on the Unit 1 Train B LOSP/SI sequencer B2G modification on October 14, 2009, and subsequently implemented this modification on the remaining three sequencers, completing the modification of Unit 2 Train 'A' LOSP/SI sequencer B2F on March 19, 2010. On April 30, 2010, Farley Nuclear Plant Unit 2 was is Mode 6, with greater than 23 feet of water above the reactor vessel. The licensee established initial conditions including removal off-site power from Train 'A' 4160 volt safety-related electrical bus 2F, and stopped both RHR pumps. The licensee performed FNP-2-STP-40.0 to verify proper operation of Unit 2 Train 'A' LOSP/SI sequencer B2F, which also restarted both RHR pumps and powered Train 'A' 4160 volt safety-related electrical bus 2F from the 1-2A EDG. The licensee performed the procedure restoration steps, requiring the resetting of sequencer B2F. FNP-2-STP-40.0 left the Test Trip Override Switch in its "on" position, this caused the output breaker of the 1-2A EDG to open, causing a momentary loss of power to the Train 'A' 4160 volt safety-related bus, resulting in an unplanned LOSP. The EDG output breaker reclosed, and sequencer B2F ran though its sequence of restarting loads (approximately two minutes for the entire sequencing).

During implementation of the design change to the emergency LOSP/SI sequencers, the licensee failed to update station procedures FNP-1-STP-40.0 (Unit 1) and FNP-2-STP-40.0 (Unit 2), to include a requirement to place the Test Trip Override Switch in the "off" position prior to resetting the associated LOSP/SI sequencer. This step was necessary to prevent the opening of the associated EDG output breaker during the resetting of the sequencer. Following the unplanned LOSP event, the licensee implemented a temporary procedure change, and promptly restored plant components to their required conditions for the current plant mode of operation. The licensee documented the event in CR 2010105854.

Analysis The failure to modify surveillance test procedure FNP-2-STP-40.0, SI with LOSP Test, following the implementation of a modification to the LOSP/SI sequencer on both units, resulting in an inadequate procedure, was a performance deficiency. This resulted in an unplanned LOSP on Unit 2 Train 'A' 4160 volt safety-related electrical bus 2F, due to the improper control the Test Trip Override Switch on the Unit 2 LOSP/SI sequencer B2F. The finding was more than minor because it adversely affected the procedure quality attribute of the Mitigating Systems cornerstone objective of ensuring the availability, reliability, and capability of systems responding to initiating events to prevent undesirable consequences (i.e. core damage). Specifically, this finding affected the ability of the Unit 2 Train 'A' 4160 volt safety-related 2F electrical bus to provide power to engineered safeguards feature components. The significance of this finding was assessed using the Phase 1 screening worksheets of Attachment 4 and Appendix G, Attachment 1, Checklist 4 of Manual Chapter 0609, SDP. The inspectors determined because the Unit was in Mode 6, with greater than 23 feet of water above the reactor vessel, that Checklist 4 was the appropriate evaluation tool. The inspectors determined the finding was of very low safety significance (Green) because the finding did not increase the likelihood of a loss of RCS inventory or degrade the licensees' ability to terminate a leak path or add to RCS inventory. This finding was assigned a cross-cutting aspect in the Resources component of the Human Performance area in that complete, accurate, and up-to-date procedures were not provided (H.2(c)). Enforcement 10 CFR 50, Appendix B, Criterion V states, in part, that activities affecting quality shall be prescribed by documented instructions, procedures or drawings of a type appropriate to the circumstances, and shall be accomplished in accordance with these instructions, procedures or drawings. Contrary to the above, the licensee failed to change station procedures FNP-1-STP-40.0 and FNP-2-STP-40.0 to include a requirement to place the Test Trip Override Switch in "OFF" position prior to resetting the associated LOSP/SI sequencer. The licensee immediately restored compliance on Unit 2 with a temporary change to its procedure. The licensee also implemented corrective actions to address the oversight in the remaining station procedures. Because this finding is of very low safety significance (Green), and is entered into the licensees' CAP as CR 2010105854, this finding is being treated as an NCV consistent with the NRC Enforcement Policy: NCV 05000364/2010004-03, Inadequate Procedure Leads to LOSP on Unit 2 4160 volt Safety-Related Bus. This LER is closed.

Failure to Deactivate Containment Isolation Valve

a. Inspection Scope

On January 15, 2010, the licensee performed a local leak rate test (LLRT) on Unit 1 containment purge exhaust penetration number 13. The licensee misidentified the outside containment mini-purge valve (Q1P13HV2876C), as leaking past its seat. The licensee entered T.S. 3.6.3, Containment Isolation Valves, which required at least one closed and deactivated valve in the affected flow path within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of detection of excessive penetration leakage. The licensee promptly closed the inside containment mini-purge valve (Q1P13HV2876D), and deactivated the valve as required by TS 3.6.3. On January 26, 2010, following additional troubleshooting, the licensee discovered the inside containment purge valve (Q1P13V283) had seat leakage, and the outside containment mini-purge valve (Q1P13HV2876C) was not leaking past its seat. During the time the inside CTMT isolation valves were closed and deactivated, the outside CTMT Mini-Purge valve was not deactivated. The licensee closed and deactivated the outside containment mini-purge valve (Q1P13HV2876C) as required by TS 3.6.3.

The inspectors reviewed the LER, the licensees' cause determination and licensee planned and completed corrective actions. The inspectors interviewed station personnel to gain understanding of the licensee activities related to the event. The inspectors reviewed applicable procedures related to the event, reviewed WOs related to the event and past work performed on these valves.

b. Findings

One LIV was identified and is documented in section

4OA7 of this report.

4OA5 Other Activities

.1 Quarterly Resident Inspector Observations of Security Personnel and Activities

a. Inspection Scope

During the inspection period, the inspectors conducted observations of security force personnel and activities to ensure these activities were consistent with licensee security procedures and regulatory requirements relating to nuclear plant security. These observations took place during both normal and off-normal plant working hours. These quarterly resident inspector observations of security force personnel and activities did not constitute any additional inspection samples. Rather, they were considered an integral part of the inspectors' normal plant status reviews and inspection activities.

b. Findings

No findings were identified.

.2 Resident Inspector Observations of Independent Spent Fuel Storage Installation

a. Inspection Scope

The licensee performed a dry fuel cask loading campaign during this inspection period.

The inspectors monitored daily activities to ensure the activities were accomplished per station procedures. The inspectors walked down the cooling systems related to loading and drying activities of the Multi-Purpose Canister (MPC). The inspectors also reviewed licensees' compensatory measures for alternate cooling and the maintenance of water level in the MPC during fuel loading. The inspectors reviewed changes made to licensee procedures since the last dry fuel cask loading campaign in 2008 to verify the changes were consistent with the licensee and Certificate of Compliance, and did not reduce the program effectiveness.

b. Findings

No findings were identified.

4OA6 Meetings, Including Exit

On October 21, 2010, the NRC inspectors presented the inspection results to Mr. Randy Johnson and other members of the Farley Nuclear Plant staff who acknowledged the findings. The NRC confirmed proprietary information was properly identified and controlled during this inspection.

4OA7 Licensee Identified Violations

The following violation of very low safety significance was identified by the licensee, and was a violation of NRC requirements and met the criteria of the NRC Enforcement Policy, for being dispositioned as an NCV.

  • TS 3.6.3, Containment Isolation Valves, requires that each containment isolation valve shall be operable in Modes 1, 2, 3 and 4. Condition D requires one or more penetration flow paths containing containment purge valves with penetration leakage, such that with the sum of the leakage for all Type B and C tests, is not within limits, the affected penetration flow path is isolated by use of at least one closed and deactivated automatic valve, closed manual valve or blind flange within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Contrary to the above, on January 15, 2010, Unit 1 containment purge exhaust penetration number 13 was declared inoperable due to excessive leakage, but the wrong containment mini-purge valve (Q1P13HV2867D) was closed and deactivated. This was corrected on January 26, 2010, when, as the result of additional troubleshooting, the licensee discovered the main containment purge valve (Q1P13V283) had seat leakage resulting in the excessive leakage identified during the LLRT on January 15, 2010. Immediately following the discovery on January 26, 2010, the licensee closed and deactivated containment mini-purge valve (Q1P13HV2867C) as required by TS 3.6.3. The licensee entered this condition in its CAP as CR 2010100931. This finding was assessed using IMC 0609, Phase 1 screening worksheets of Attachments 4 and Appendix H relating to Containment Barrier Integrity, and determined to be of very low safety significance (Green) because the leaking penetration would not have allowed the entire volume of containment to exit through the opening within a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period.
