Attachment 1 Shutdown Operations Significance Determination Process Phase 1 Operational Checklists for both PWRs and BWRs dated May 25, 2004 using Checklists 1 through 4. Appendix G was utilized since both units would have been shutdown prior to the probable maximum hurricane (PMH) event and associated external flood. Due to the accuracy of weather forecasting, there would be several days for the licensee to prepare for a PMH. The inspectors reviewed the finding with the regional senior reactor analyst and determined that the licensee would have adequate time to ensure that the mitigating capability of core heat removal, inventory control, emergency AC power, containment control, or reactivity control systems would have been available prior to the PMH affecting the site. | |||
The finding screened as Green because none of the attributes in the checklists were adversely impacted. No cross cutting aspects were assigned to the finding. The finding does not represent current licensee performance because the degraded and missing penetration seals have existed since original construction of the plant. (Section 4OA3.2) | |||

An NRC identified non-cited violation of 10 CFR 50, Appendix B, Criterion XVI, "Corrective Action," was identified for the failure to promptly identify and correct a condition adverse to quality (CAQ) involving alignment of the safety-related refueling water tank (RWT) to a non-seismic spent fuel pool (SFP) purification system.

Specifically the | The finding was more than minor because it affected the configuration control attribute of the mitigating systems cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically the alignment of the safety-related RWT to the non-seismic SFP purification system created a CAQ and rendered the RWT inoperable for greater than its allowed outage time. The inspectors evaluated the finding in accordance with NRC Inspection Manual Chapter 0609, Significant Determination Process, Attachment and Appendix A and determined that the finding required a phase 3 evaluation by a senior reactor analyst. The analyst calculated the change in conditional core damage probability (CCDP) due to the postulated loss of the RWT during an event, multiplied by the frequency of a seismic event that could require the use of the RWT (e.g., loss of coolant accident) and applied an exposure time factor (4 days/7 days). The dominant sequence was a steam generator tube rupture which proceeds to core damage due to a lack of high or low pressure injection water supply. The risk was mitigated by the low probability of a seismic event. The analysis determined that the risk increase of the performance deficiency was an increase in large early release frequency less than 1E-7/year which is a GREEN finding of very low safety significance. The cause of the finding involved the cross-cutting area of problem identification and resolution, the component of corrective action program, and the aspect of complete and thorough evaluation, P.1(c); because the licensee failed to properly evaluate for operability the practice of aligning a seismically qualified RWT to a non-seismic purification system.

On March 18, 2012, the Unit 1 operating crew was performing rod worth measurements by rod swap in accordance with the zero power physics test procedure. As regulating group 3 was being inserted by operators to establish the required negative reactivity for the test, six of the eight control element assemblies (CEAs) continued to insert when the rod control switch was released. Operators promptly recognized the undemanded negative reactivity insertion and took action to place rod select power in off. This action terminated the inward motion of the six affected control element assemblies.

The inspectors noted that procedure 3200091, Appendix H, Actions for Misaligned CEA during Unit 1 HZP Physics Testing, detailed immediate operator actions to perform in response to misaligned CEAs during the test. The inspectors also noted that the operator actions provided by Appendix H paralleled those contained in the abnormal operating procedure for a dropped or misaligned CEA. The immediate operator actions, in part, required operators to ensure that rod select power was off; and, if more than two CEAs were misaligned by greater than 15 inches, then to manually trip the reactor as directed by the shift manager or unit supervisor. The inspectors reviewed rod position data to determine the amount of CEA misalignment that occurred as a result of the CEA malfunction. The inspectors determined that at the time that the rod select power was first secured to terminate inward CEA motion, six of the affected CEAs were misaligned by approximately 21 inches. After the operators restored power to the CEAs to check for control, the affected CEAs inserted an additional three inches before operators manually tripped the unit. The inspectors learned that when the operators first secured rod select power and discussed necessary actions to stabilize the unit, the operators had not reviewed or otherwise checked indicated rod positions and were unaware that six of the eight CEAs were misaligned by greater than 15 inches before restoring power to the CEAs. The operators also stated they did not enter Appendix H of the test procedure and were concerned with taking prompt action to determine of CEA control could be maintained in order to stop the negative reactivity transient that was occurring.

The inspectors concluded that the failure to follow the immediate operator actions for misaligned CEAs as described by Appendix H of the reload startup physics testing procedure was a performance deficiency. Specifically, the procedure directed operators to respond to CEA misalignment by manually tripping the unit if more than two CEAs were misaligned by greater than 15 inches, and contrary to those actions, operators responded to a CEA malfunction by restoring power to CEAs that were misaligned by 21 inches prior to tripping the unit. | The inspectors concluded that the failure to follow the immediate operator actions for misaligned CEAs as described by Appendix H of the reload startup physics testing procedure was a performance deficiency.

The inspectors screened the performance deficiency in accordance with Inspection Manual Chapter (IMC) 0612, Appendix B, Issue Screening, dated September 7, 2012, and determined that, in this case, the performance deficiency was minor. The minor determination was based on operator actions taken in response to an insertion of negative reactivity into a sub critical core. Also, the impact of three additional inches of CEA misalignment on core flux which resulted from the performance deficiency was minimal. Therefore, the inspectors concluded that the performance deficiency was not a precursor to a significant event, would not have led to a more significant safety concern, did not relate to a performance indicator, and did not adversely affect a cornerstone objective. | The inspectors screened the performance deficiency in accordance with Inspection Manual Chapter (IMC) 0612, Appendix B, Issue Screening, dated September 7, 2012, and determined that, in this case, the performance deficiency was minor.

The inspectors noted that in October 2010 there were two ARs entered into the licensees CAP for an operating experience (OE) event involving another utility who later received a non-cited violation for a similar occurrence in which a safety-related refueling water storage tank (RWST) was aligned to a non-seismic purification system. The first AR (583881) contained preliminary OE information and had an assignment to review operating experience for site applicability. This assignment was cancelled without explanation. A second AR (589182) documented a discussion by NRC OE staff during an October 20, 2010 Reactor Oversight Process task force meeting. The discussion centered on the same industry event described above where operators had aligned the seismically qualified tank to a non-safety, non-seismically qualified system during power operations. The AR documented the NRCs position that the operators at the utility should have declared the RWST inoperable and entered the | ||
[technical specification (TS)] action statement and the NRC is pursuing a finding as a technical specification compliance issue. The licensees evaluation of this second AR resulted in their determination that they were within their design basis and the RWT remained operable while aligned to the non-seismic system. This conclusion was based on the use of manual operator actions to isolate the non-seismic system from the RWT after a seismic event. The licensee also determined that it was very unlikely that the non-seismic piping would fail and if it does fail and leak, manual operator actions in place would isolate the non-seismic purification system from the RWT before the RWT water level reached technical specification limits. The corrective actions for this AR included procedure changes to maintain a higher minimum RWT water level during periods the tank was aligned to purification. This would allow up to 30 minutes (a change from 20 minutes) for the manual operator actions. | |||
In April 2012, in response to NRC Information notice (IN) 2012-01, Seismic Considerations - Principally Issues Involving Tanks, the licensee initiated AR1769593. This IN specifically stated that TSs would not allow applying compensatory measures, such as manual actions in place of a closed boundary valve, for periods longer than the TS completion time for restoring the RWST to operable status. Corrective actions included implementing administrative actions to preclude this alignment when the RWT is required to be operable. Prior to April 2012, each units RWT had been routinely aligned to its SFP purification system 3 to 4 days each week for tank cleanup. The inspectors review of the LER revealed that the cause of the event was incorrect application of compensatory measures for planned maintenance activities. | |||
The inspectors concluded that the licensee did not identify a CAQ regarding the inoperability of the RWT when aligned to the non-safety-related SFP purification system because a complete and thorough evaluation was not performed during the review of two 2010 ARs noted above. | The inspectors concluded that the licensee did not identify a CAQ regarding the inoperability of the RWT when aligned to the non-safety-related SFP purification system because a complete and thorough evaluation was not performed during the review of two 2010 ARs noted above. | ||
=====Analysis:===== | =====Analysis:===== | ||
The failure to promptly identify and correct the CAQ for the alignment of the RWT to the SFP purification system was a performance deficiency. The performance deficiency was more than minor because it affected the configuration control attribute of the mitigating systems cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically the alignment of the safety-related RWT to the non-seismic SFP purification system created a CAQ and rendered the RWT inoperable for greater than its allowed outage time.

The performance deficiency was more than minor because it affected the configuration control attribute of the mitigating systems cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically the alignment of the safety-related RWT to the non-seismic SFP purification system created a CAQ and rendered the RWT inoperable for greater than its allowed outage time. The inspectors evaluated the finding in accordance with NRC IMC 0609, Significant Determination Process, Attachment 4 and Appendix A and determined that the finding required a phase 3 evaluation by a senior reactor analyst. The analyst calculated the change in conditional core damage probability (CCDP) due to the postulated loss of the RWT during an event, multiplied by the frequency of a seismic event that could require the use of the RWT (e.g., loss of coolant accident) and applied an exposure time factor (4 days/7 days). The dominant sequence was a steam generator tube rupture which proceeds to core damage due to a lack of high or low pressure injection water supply. The risk was mitigated by the low probability of a seismic event. The analysis determined that the risk increase of the performance deficiency was an increase in large early release frequency less than 1E-7/year which is a GREEN finding of very low safety significance. | ||

The licensee later submitted Supplement 1 to the LER in order to communicate the results of the root cause evaluation and the status of corrective actions. The licensee identified that the root cause of the issue was inadequate design control measures which introduced signal noise into the timing modules of the CEAs. The signal noise was incompatible with test equipment being used to perform zero power physics testing and resulted in unexpected CEA movement during performance of the test. | |||
The inspectors reviewed the LER (including Supplement 1), the licensees root cause evaluation, and the post-trip report to gain a better understanding of the circumstances which led to manual reactor trip and to verify that the plant systems and operators responded to the event as required. In addition, the inspectors performed an in-depth review of the operators actions in response to the unexpected rod movement that is documented in Section 4OA2.2 of this report. The inspectors evaluated the accuracy of the information submitted in the LER, licensee conformance with regulatory requirements, and potential generic implications related to the event. Additionally, the inspectors evaluated the licensees corrective actions to determine if the actions appropriately addressed the causes that were identified in the licensees root cause evaluation. The LER and its associated supplement were reviewed. A minor violation related to operator actions taken in response to the unexpected rod motion is documented in Section 4OA2.2 of this report.

The RAB flooding would exceed the amount analyzed in the internal flooding analysis and could have resulted in the loss of both boric acid transfer pumps. Safety-related equipment necessary to maintain the unit in a safe shutdown condition would not have been impacted.

=====Analysis:===== | =====Analysis:===== | ||
The performance deficiency associated with this finding involved the | The performance deficiency associated with this finding involved the licensees failure to comply with the requirements of 10 CFR Part 50, Appendix B, Criterion III, Design Control. Specifically, since original plant construction, the licensee failed to maintain Unit 1 and 2 RAB penetrations in accordance with design requirements. This finding is more than minor because it affects the protection against external factors attribute of the mitigating system cornerstone, and affected the cornerstone objective of ensuring availability, reliability, and capability of systems that respond to initiating events. Using Manual Chapter 0609.04, Initial Characterization of Findings, Table 2, dated June 19, 2012, the finding was determined to affect an external event mitigation system and affected the Mitigating System cornerstone. Although the finding existed with the units at power and during shutdown conditions since original plant construction, the risk was assessed using Manual Chapter 0609 Appendix G, Attachment 1 Shutdown Operations Significance Determination Process Phase 1 Operational Checklists for both PWRs and BWRs dated May 25, 2004 using checklists 1 through 4. Appendix G was utilized since both units would have been shutdown prior to the PMH event and associated external flood. Due to the accuracy of weather forecasting, there would be several days for the licensee to prepare for a PMH. The inspectors reviewed the finding with the regional senior reactor analyst and determined that the licensee would have adequate time to ensure that the mitigating capability of core heat removal, inventory control, emergency AC power, containment control, or reactivity control systems would have been available prior to the PMH affecting the site. The finding screened as Green because none of the attributes in the checklists were adversely impacted. | ||
No cross cutting aspects were assigned to the finding.

The | 10 CFR 50, Appendix B, Criterion III, Design Controls, requires, in part, that measures shall be established to assure that applicable regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures and instructions. These measures shall include provisions to assure that appropriate quality standards are specified and included in design documents and that deviations from such standards are controlled. The licensees design basis does not allow for any external leakage into safety-related buildings during a PMH. Unit 1 UFSAR section 3.4.4, states in part, that All external building penetrations are waterproofed and/or flood protected to preclude the failure of safety related system or component due to external flooding. Unit 2 UFSAR, section 2.4.2.2.b states, in part, Flood protection criteria is established at elevation 19.5 feet MLW whereby exterior doors and penetrations which lead to areas containing safety related equipment are made watertight through use of boots, waterstops and waterproofing. Unit 1, licensee drawing 8770-B-328, sheet 4A, Revision 6, specifies that all ductbank entry into safety related buildings at or below the PMH flood level shall be sealed. Unit 2 drawing 2998-C-348, sheet 1, Revision 5, specifies that all conduit entries into safety related buildings at or below grade shall be sealed. | ||
Contrary to the above, the licensee did not assure that deviations from the design basis were controlled when below grade conduit penetrations were originally installed. Additionally, other seals that were originally installed were not maintained. | |||
Specifically, in September 2012, the licensee identified Unit 1 and 2 degraded and missing conduit penetrations seals that had not been originally installed or maintained as required by the design basis. As a result, during PMH conditions, water in-leakage through the penetrations would result in the flooding of the -0.5 foot elevation of both units RAB. The flooding could have resulted in the loss of both Unit 1 boric acid makeup pumps. Because the licensee entered the issue into their corrective action program as ARs 1804496 and 1800822, and the finding is of very low safety significance (Green), this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 05000335, 389/2013002-02, Failure to Ensure Reactor Auxiliary Building Penetrations were Adequately Flood Protected. | |||

This relay actuation caused a differential current lockout on the electrical bus. The evaluation concluded that the plant personnel were not fully aware of the risk significance associated with the unprotected differential relay terminals as a result of not having performed an adequate work assessment of the immediate work area as required by licensees conduct of maintenance procedure prior to starting the work. Due to ongoing outage work, scaffolding and other equipment was in the immediate area which resulted in a small work space available to perform the planned activity.

The inspectors determined that the licensees failure to perform an adequate risk assessment of the job site as required by licensees conduct of maintenance procedure prior to starting the job activity was a performance deficiency (PD) that was not a violation of NRC requirements. | ||
The inspectors screened the performance deficiency in accordance with Inspection Manual Chapter (IMC) 0612, Appendix B, Issue Screening, dated September 7, 2012, and determined that, in this case, the performance deficiency was minor. The PD was minor because it did not cause any required safety related equipment to become inoperable as this job was planned well in advance and was scheduled to occur during a time that the B electrical train was not required to be operable. The inspectors concluded that the PD was not a precursor to a significant event, did not have the potential to lead to a more significant safety concern, was not related to a performance indicator that would have caused the performance indicator to exceed a threshold, and did not adversely affect any of the cornerstone objectives listed at the end of manual chapter 0612 Appendix B.

ST. LUCIE NUCLEAR PLANT - NRC INTEGRATED INSPECTION REPORT 05000335/2013002, 05000389/2013002 AND EMERGENCY PREPAREDNESS REPORT 05000335/2013501, 05000389/2013501
Dear Mr. Nazar:
On March 31, 2013, the US Nuclear Regulatory Commission (NRC) completed an inspection at your St. Lucie Nuclear Power Plant Units 1 and 2. The enclosed integrated inspection report documents the inspection results, which were discussed on April 8, 2013, with Mr. Jensen and other members of your staff.
The inspection examined activities conducted under your license as they related to safety and compliance with the Commissions rules and regulations and with the conditions of your license.
The inspectors reviewed selected procedures and records, observed activities, and interviewed personnel.
Two NRC identified findings of very low safety significance (Green) were identified during this inspection. These two findings were determined to involve violations of NRC requirements and are being treated as non-cited violations (NCVs), consistent with Section 2.3.2 of the Enforcement Policy.
If you contest the violations or significance of these NCVs, 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 the St. Lucie Nuclear Power Plant.
If you disagree with a 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 II; and the NRC Resident Inspector at the St. Lucie Nuclear Power Plant. In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of the NRCs document system (ADAMS). Adams is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

Design Control, was identified for the licensees failure to ensure that all below grade Unit 1 and 2 reactor auxiliary building (RAB) penetrations were adequately sealed as required by the licensees design basis. The missing and degraded penetration seals were found during licensee inspections performed in response to a letter from the NRC to licensees, entitled Request for Information Pursuant to Title 10 of the Code of Federal Regulations 50.54(f)
Regarding Recommendations 2.1, 2.3, and 9.3, of the Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident, dated March 12, 2012 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML12053A340).
Corrective actions completed included restoring the degraded or missing seals to design basis requirements.
The performance deficiency was determined to be more than minor because it affected the protection against external factors attribute of the mitigating system cornerstone, and affected the cornerstone objective of ensuring availability, reliability, and capability of systems that respond to initiating events. Using Manual Chapter 0609.04, Initial Characterization of Findings, Table 2, dated June 19, 2012, the finding was determined to affect an external event mitigation system and affected the mitigating system cornerstone.
Although the finding existed with the units at power and during shutdown conditions since original plant construction, the risk was assessed using Manual Chapter 0609 Appendix G,
Attachment 1 Shutdown Operations Significance Determination Process Phase 1 Operational Checklists for both PWRs and BWRs dated May 25, 2004 using Checklists 1 through 4. Appendix G was utilized since both units would have been shutdown prior to the probable maximum hurricane (PMH) event and associated external flood. Due to the accuracy of weather forecasting, there would be several days for the licensee to prepare for a PMH. The inspectors reviewed the finding with the regional senior reactor analyst and determined that the licensee would have adequate time to ensure that the mitigating capability of core heat removal, inventory control, emergency AC power, containment control, or reactivity control systems would have been available prior to the PMH affecting the site.
The finding screened as Green because none of the attributes in the checklists were adversely impacted. No cross cutting aspects were assigned to the finding. The finding does not represent current licensee performance because the degraded and missing penetration seals have existed since original construction of the plant. (Section 4OA3.2)
- Green.
An NRC identified non-cited violation of 10 CFR 50, Appendix B, Criterion XVI,
"Corrective Action," was identified for the failure to promptly identify and correct a condition adverse to quality (CAQ) involving alignment of the safety-related refueling water tank (RWT)to a non-seismic spent fuel pool (SFP) purification system. Corrective actions included implementing administrative actions to preclude this alignment when the RWT is required to be operable.
The finding was more than minor because it affected the configuration control attribute of the mitigating systems cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically the alignment of the safety-related RWT to the non-seismic SFP purification system created a CAQ and rendered the RWT inoperable for greater than its allowed outage time. The inspectors evaluated the finding in accordance with NRC Inspection Manual Chapter 0609, Significant Determination Process, Attachment and Appendix A and determined that the finding required a phase 3 evaluation by a senior reactor analyst. The analyst calculated the change in conditional core damage probability (CCDP) due to the postulated loss of the RWT during an event, multiplied by the frequency of a seismic event that could require the use of the RWT (e.g., loss of coolant accident) and applied an exposure time factor (4 days/7 days). The dominant sequence was a steam generator tube rupture which proceeds to core damage due to a lack of high or low pressure injection water supply. The risk was mitigated by the low probability of a seismic event. The analysis determined that the risk increase of the performance deficiency was an increase in large early release frequency less than 1E-7/year which is a GREEN finding of very low safety significance. The cause of the finding involved the cross-cutting area of problem identification and resolution, the component of corrective action program, and the aspect of complete and thorough evaluation, P.1(c); because the licensee failed to properly evaluate for operability the practice of aligning a seismically qualified RWT to a non-seismic purification system. (Section 4OA2.3)

1R20 Refueling and Other Outage Activities
Unit 1 forced outage March 12
a. Inspection Scope
On March 12, with the unit at full power, Unit 1 automatically tripped when a thermal margin/low pressure (TMLP) trip setpoint was exceeded. The TMLP setpoint is based, in part, on inputs associated with the differential steam pressure between A and B steam generators. The trip setpoint was exceeded due to the interruption of steam flow from the B steam generator. During the outage, the licensee completed internal inspections of both MSIVs. The inspections identified contact between the valve disc swing arm and the valve body on both valves which resulted in additional stress placed on the actuator-to-valve disc linkage assemblies when the valves were in the open position. The B MSIV linkage assembly failed causing the valve to close.
The A MSIV linkage assembly was found damaged. Both valves were repaired.
Monitoring of Shutdown Activities The inspectors observed portions of the cooldown process to verify that technical specification cooldown restrictions were followed. The inspectors conducted a containment walkdown after the shutdown to assess the condition of the systems within containment that are inaccessible with the unit at power.

.2 Annual Sample Review - Operator Actions in Response Unexpected Movement of
Control Element Assemblies
a. Inspection Scope
The inspectors performed a more in-depth review of action request (AR) 1746072 to evaluate the operators response to unexpected rod movement that occurred during zero power physics testing on March 18, 2012. The inspectors reviewed control room logs and the licensees post trip report including the transient assessment and operating crew statements. The inspectors interviewed licensee personnel and evaluated the operators response to the event using the guidance provided in the following licensee procedures:
- 1-AOP-66.01, Dropped or Misaligned CEA Abnormal Operations
- 3200091, Reload Startup Physics Testing
- OP-AA-100-1000, Conduct of Operations
- OP-AA-103-1000, Reactivity Management The licensee had previously submitted licensee event report (LER) 05000335/2012-002-00 and supplement 01 of the LER to the NRC to report the manual reactor trip that occurred as a result of the rod movement. The inspectors review of the licensees root cause analysis and corrective actions taken to address the control element assembly malfunction, as well as the closure of the LER and associated supplement, is documented in Section 4OA3 of this report.
b. Findings and Observations
On March 18, 2012, the Unit 1 operating crew was performing rod worth measurements by rod swap in accordance with the zero power physics test procedure. As regulating group 3 was being inserted by operators to establish the required negative reactivity for the test, six of the eight control element assemblies (CEAs) continued to insert when the rod control switch was released. Operators promptly recognized the undemanded negative reactivity insertion and took action to place rod select power in off. This action terminated the inward motion of the six affected control element assemblies. The operating crew then discussed the CEA insertion and elected to restore rod select power and monitor CEA response to determine if operator control of the CEAs could be restored. The operators restored rod select power and six of the eight CEAs continued to insert without operator demand. Operators immediately placed rod select power to off and manually tripped the unit. The trip was uncomplicated and the operators carried out post-trip actions.
The inspectors noted that procedure 3200091, Appendix H, Actions for Misaligned CEA during Unit 1 HZP Physics Testing, detailed immediate operator actions to perform in response to misaligned CEAs during the test. The inspectors also noted that the operator actions provided by Appendix H paralleled those contained in the abnormal operating procedure for a dropped or misaligned CEA. The immediate operator actions, in part, required operators to ensure that rod select power was off; and, if more than two CEAs were misaligned by greater than 15 inches, then to manually trip the reactor as directed by the shift manager or unit supervisor. The inspectors reviewed rod position data to determine the amount of CEA misalignment that occurred as a result of the CEA malfunction. The inspectors determined that at the time that the rod select power was first secured to terminate inward CEA motion, six of the affected CEAs were misaligned by approximately 21 inches. After the operators restored power to the CEAs to check for control, the affected CEAs inserted an additional three inches before operators manually tripped the unit. The inspectors learned that when the operators first secured rod select power and discussed necessary actions to stabilize the unit, the operators had not reviewed or otherwise checked indicated rod positions and were unaware that six of the eight CEAs were misaligned by greater than 15 inches before restoring power to the CEAs. The operators also stated they did not enter Appendix H of the test procedure and were concerned with taking prompt action to determine of CEA control could be maintained in order to stop the negative reactivity transient that was occurring. The inspectors also noted that the licensees post trip review of crew performance did not identify that the operators decision to restore rod select power in response to CEA misalignment was not consistent with immediate operator actions specified by Appendix H of the test procedure.
The inspectors concluded that the failure to follow the immediate operator actions for misaligned CEAs as described by Appendix H of the reload startup physics testing procedure was a performance deficiency. Specifically, the procedure directed operators to respond to CEA misalignment by manually tripping the unit if more than two CEAs were misaligned by greater than 15 inches, and contrary to those actions, operators responded to a CEA malfunction by restoring power to CEAs that were misaligned by 21 inches prior to tripping the unit.
The inspectors screened the performance deficiency in accordance with Inspection Manual Chapter (IMC) 0612, Appendix B, Issue Screening, dated September 7, 2012, and determined that, in this case, the performance deficiency was minor. The minor determination was based on operator actions taken in response to an insertion of negative reactivity into a sub critical core. Also, the impact of three additional inches of CEA misalignment on core flux which resulted from the performance deficiency was minimal. Therefore, the inspectors concluded that the performance deficiency was not a precursor to a significant event, would not have led to a more significant safety concern, did not relate to a performance indicator, and did not adversely affect a cornerstone objective.
The inspectors determined that the performance deficiency resulted in a minor violation of St. Lucie Technical Specification 6.8.1.a, Procedures and Programs, because Appendix H of the test procedure was required to be implemented by Section 6 of Appendix A to Regulatory Guide 1.33, Quality Assurance Program Requirements, Revision 2. Compliance with operator actions specified in Appendix H of the test procedure was restored when the operators ultimately did perform a manual trip of the reactor as required by the procedure. In response to the inspectors conclusions, the licensee entered this issue into the corrective action program as AR 1858250. This failure to comply with technical specification 6.8.1.a constitutes a minor violation that is not subject to enforcement action in accordance with the NRCs Enforcement Policy.
.3 Annual Sample: Apparent Cause Evaluation Associated with Aligning Seismically
Qualified Refueling Water Tanks to Non-Seismic Piping
a. Inspection Scope
On August 20, 2012, the licensee issued Licensee Event Report (LER) 05000335, 389/2012-004-00 documenting the past practice of aligning both units seismically qualified safety-related refueling water tank (RWT) to a non-seismic, non-safety-related spent fuel pool (SFP) purification system rendering the tank inoperable when required in Modes 1 - 4. Licensee action request (AR) 1756212 addressed the corrective actions associated with the LER. The AR was reviewed by the inspectors in detail to evaluate the effectiveness of the licensees corrective actions. The inspectors also assessed whether the issue was properly identified, documented accurately and completely, properly classified and prioritized, adequately considered extent of condition, generic implications, common cause, and previous occurrences, adequately identified root causes/apparent causes, and identified appropriate and timely corrective actions. The inspectors verified the licensees actions were in accordance with licensee procedures, PI-AA-204, Condition Identification and Screening, and PI-AA-205, Condition Evaluation and Corrective Actions. The closure of the LER is documented in section 4OA3.3 of this report.
b. Findings and Observations
The inspectors determined that the licensee had an opportunity to identify and correct this issue approximately a year prior to the issuance of a related NRC Information Notice. A non-cited violation is documented below.
Introduction:
A Green, non-cited violation of 10 CFR 50, Appendix B, Criterion XVI, "Corrective Action," was identified by the inspectors for the failure to promptly identify and correct a condition adverse to quality (CAQ) involving alignment of the safety-related RWT to a non-seismic SFP purification system.
Description:
The inspectors reviewed historical corrective action program (CAP)documents relating to the problem documented in the LER. The inspectors noted that in October 2010 there were two ARs entered into the licensees CAP for an operating experience (OE) event involving another utility who later received a non-cited violation for a similar occurrence in which a safety-related refueling water storage tank (RWST) was aligned to a non-seismic purification system. The first AR (583881) contained preliminary OE information and had an assignment to review operating experience for site applicability. This assignment was cancelled without explanation. A second AR (589182) documented a discussion by NRC OE staff during an October 20, 2010 Reactor Oversight Process task force meeting. The discussion centered on the same industry event described above where operators had aligned the seismically qualified tank to a non-safety, non-seismically qualified system during power operations. The AR documented the NRCs position that the operators at the utility should have declared the RWST inoperable and entered the
[technical specification (TS)] action statement and the NRC is pursuing a finding as a technical specification compliance issue. The licensees evaluation of this second AR resulted in their determination that they were within their design basis and the RWT remained operable while aligned to the non-seismic system. This conclusion was based on the use of manual operator actions to isolate the non-seismic system from the RWT after a seismic event. The licensee also determined that it was very unlikely that the non-seismic piping would fail and if it does fail and leak, manual operator actions in place would isolate the non-seismic purification system from the RWT before the RWT water level reached technical specification limits. The corrective actions for this AR included procedure changes to maintain a higher minimum RWT water level during periods the tank was aligned to purification. This would allow up to 30 minutes (a change from 20 minutes) for the manual operator actions.
In April 2012, in response to NRC Information notice (IN) 2012-01, Seismic Considerations - Principally Issues Involving Tanks, the licensee initiated AR1769593. This IN specifically stated that TSs would not allow applying compensatory measures, such as manual actions in place of a closed boundary valve, for periods longer than the TS completion time for restoring the RWST to operable status. Corrective actions included implementing administrative actions to preclude this alignment when the RWT is required to be operable. Prior to April 2012, each units RWT had been routinely aligned to its SFP purification system 3 to 4 days each week for tank cleanup. The inspectors review of the LER revealed that the cause of the event was incorrect application of compensatory measures for planned maintenance activities.
The inspectors concluded that the licensee did not identify a CAQ regarding the inoperability of the RWT when aligned to the non-safety-related SFP purification system because a complete and thorough evaluation was not performed during the review of two 2010 ARs noted above.
Analysis:
The failure to promptly identify and correct the CAQ for the alignment of the RWT to the SFP purification system was a performance deficiency. The performance deficiency was more than minor because it affected the configuration control attribute of the mitigating systems cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically the alignment of the safety-related RWT to the non-seismic SFP purification system created a CAQ and rendered the RWT inoperable for greater than its allowed outage time. The inspectors evaluated the finding in accordance with NRC IMC 0609, Significant Determination Process, Attachment 4 and Appendix A and determined that the finding required a phase 3 evaluation by a senior reactor analyst. The analyst calculated the change in conditional core damage probability (CCDP) due to the postulated loss of the RWT during an event, multiplied by the frequency of a seismic event that could require the use of the RWT (e.g., loss of coolant accident) and applied an exposure time factor (4 days/7 days). The dominant sequence was a steam generator tube rupture which proceeds to core damage due to a lack of high or low pressure injection water supply. The risk was mitigated by the low probability of a seismic event. The analysis determined that the risk increase of the performance deficiency was an increase in large early release frequency less than 1E-7/year which is a GREEN finding of very low safety significance.
The cause of the finding involved the cross-cutting area of problem identification and resolution, the component of corrective action program, and the aspect of complete and thorough evaluation, P.1(c), because the licensee failed to properly evaluate for operability the practice of aligning a seismically qualified RWT to a non-seismic purification system.
Enforcement:
10 CFR 50, Appendix B, Criterion XVI states, in part, that measures shall be established to assure that CAQs are promptly identified and corrected.
Contrary to the above, in October, 2010, the licensee failed to promptly identify and correct a CAQ involving alignment of the safety-related RWT to a non-seismic SFP purification system. Because the finding was of very low safety significance (Green)and was entered into the licensees CAP as AR 1756212, this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy:
NCV 05000335, 389/2013002-01, Failure to Promptly Identify and Correct a Condition Adverse to Quality for Alignment of the Safety-Related Refueling Water Tank to a Non-Seismic Spent Fuel Pool Purification system.
4OA3 Follow-up of Events And Notices of Enforcement Discretion
.1 (Closed) Licensee Event Report (LER) 05000335/2012-002-00 (and Supplement 01)
Manual Trip during Physics Testing Due to Unexpected Movement of Control Element Assemblies (CEAs)
On March 18, 2012, while Unit 1 was subcritical and the licensee was performing zero power physics testing, the reactor was manually tripped by operators in the control room following unexpected control element assembly (CEA) movement. The manual reactor trip was uncomplicated and all CEAs fully inserted. The licensee submitted LER 05000335/2012-002-00 to the NRC in accordance with 10 CFR 50.73(a)(2)(iv)(A) as an event or condition that resulted in manual or automatic actuation of the Reactor Protection System including reactor scram or reactor trip.
The licensee later submitted Supplement 1 to the LER in order to communicate the results of the root cause evaluation and the status of corrective actions. The licensee identified that the root cause of the issue was inadequate design control measures which introduced signal noise into the timing modules of the CEAs. The signal noise was incompatible with test equipment being used to perform zero power physics testing and resulted in unexpected CEA movement during performance of the test.
The inspectors reviewed the LER (including Supplement 1), the licensees root cause evaluation, and the post-trip report to gain a better understanding of the circumstances which led to manual reactor trip and to verify that the plant systems and operators responded to the event as required. In addition, the inspectors performed an in-depth review of the operators actions in response to the unexpected rod movement that is documented in Section 4OA2.2 of this report. The inspectors evaluated the accuracy of the information submitted in the LER, licensee conformance with regulatory requirements, and potential generic implications related to the event. Additionally, the inspectors evaluated the licensees corrective actions to determine if the actions appropriately addressed the causes that were identified in the licensees root cause evaluation. The LER and its associated supplement were reviewed. A minor violation related to operator actions taken in response to the unexpected rod motion is documented in Section 4OA2.2 of this report. The LER and Supplement 1 are closed.
.2 (Closed) LER 05000335/2012-010-00, Degraded Manhole Conduit Seals Bypassed
External Flood Protection
a. Inspection Scope
On November 1, 2012, licensee engineering completed their review of the cumulative effects of degraded and missing conduit seals in the electrical manholes that provided a leakage path into Unit 1 and 2 reactor auxiliary buildings (RABs). The degraded and missing penetrations were identified during walkdowns completed in response to a letter from the NRC to licensees, entitled Request for Information Pursuant to Title 10 of the Code of Federal Regulations 50.54(f) Regarding Recommendations 2.1, 2.3, and 9.3, of the Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident, dated March 12, 2012 (ADAMS Accession No. ML12053A340).
The licensee determined that the as-found condition of Unit 1 conduit seals could have resulted in flooding of the Unit 1 RAB during a probable maximum hurricane (PMH) greater than the internal flooding analysis of record. The licensee also found similarly degraded and missing penetrations in Unit 2; however, the cumulative effect of flooding during a postulated PMH would be bounded by the internal flooding analysis. The inspectors checked the accuracy and completeness of the LER and the appropriateness of the licensees corrective actions. The inspectors reviewed the licensees flooding analysis methodology for both units and found it to be reasonable.
The inspectors walked down Unit 1 and 2 RABs to determine whether any other safety-related equipment other than the Unit 1 boric acid pumps could be impacted from flooding during a PMH. As documented in section 4OA5.3, the inspectors, on a sampling basis, also performed independent walkdowns to verify that the licensee completed the actions associated with the letter noted above.
b. Findings
Introduction:
An NRC identified non-cited violation (NCV) of 10 CFR 50, Appendix B, Criterion III, Design Control, was identified associated with the licensees failure to ensure that all below grade Unit 1 and 2 reactor auxiliary building (RAB) penetrations were adequately sealed as required by the licensees design basis. Specifically, the licensee identified Unit 1 and 2 RAB penetrations with missing or degraded seals.
The licensees design basis requires these penetrations to be waterproofed or flood protected.
Description:
In September 2012, the licensee identified below grade Unit 1 and Unit 2 RAB penetrations with missing or degraded penetration seals. The missing and degraded penetration seals were found during licensee inspections performed in response to a letter from the NRC to licensees, entitled Request for Information Pursuant to Title 10 of the Code of Federal Regulations 50.54(f) Regarding Recommendations 2.1, 2.3, and 9.3, of the Near-Term Task Force Review of Insights from the Fukushima Dai-ichi Accident, dated March 12, 2012 (Agencywide Documents Access and Management System (ADAMS) Accession No.
The licensees engineering analysis determined that the Unit 1 RAB missing and degraded penetration seals would have allowed flood water from a PMH event to enter the RAB. The RAB flooding would exceed the amount analyzed in the internal flooding analysis and could have resulted in the loss of both boric acid transfer pumps. Safety-related equipment necessary to maintain the unit in a safe shutdown condition would not have been impacted. The Unit 2 engineering analysis determined that the amount of leakage into the Unit 2 RAB was bounded by the internal flooding analysis of record and would not have impact equipment important to safety.
The inspectors reviewed the licensees engineering analysis assumptions and methodology in determining the amount of external leakage through the degraded and missing electrical penetration seals into both units RAB and determined that the assumptions and methodology were reasonable. The inspectors walked down both units RAB and determined that no other equipment important to safety would have been impacted during the event.
The significance of this issue is mitigated by the fact that both units would have been shutdown and cooled down to at least Mode 5 (<200oF) during a PMH event in accordance with licensee procedure 0005753, Severe Weather Preparations.
Procedure 0005753, required the units to be shutdown in Mode 5 (<200oF) at least two hours before the projected onset onsite of sustained hurricane force winds for a Category 4 or 5 hurricane.
This issue was placed in the licensees corrective action program as action request (AR) 1804496 (Unit 1) and AR1800822 (Unit 2). Corrective actions completed included restoring the degraded or missing seals to design requirements.
Analysis:
The performance deficiency associated with this finding involved the licensees failure to comply with the requirements of 10 CFR Part 50, Appendix B, Criterion III, Design Control. Specifically, since original plant construction, the licensee failed to maintain Unit 1 and 2 RAB penetrations in accordance with design requirements. This finding is more than minor because it affects the protection against external factors attribute of the mitigating system cornerstone, and affected the cornerstone objective of ensuring availability, reliability, and capability of systems that respond to initiating events. Using Manual Chapter 0609.04, Initial Characterization of Findings, Table 2, dated June 19, 2012, the finding was determined to affect an external event mitigation system and affected the Mitigating System cornerstone. Although the finding existed with the units at power and during shutdown conditions since original plant construction, the risk was assessed using Manual Chapter 0609 Appendix G, Attachment 1 Shutdown Operations Significance Determination Process Phase 1 Operational Checklists for both PWRs and BWRs dated May 25, 2004 using checklists 1 through 4. Appendix G was utilized since both units would have been shutdown prior to the PMH event and associated external flood. Due to the accuracy of weather forecasting, there would be several days for the licensee to prepare for a PMH. The inspectors reviewed the finding with the regional senior reactor analyst and determined that the licensee would have adequate time to ensure that the mitigating capability of core heat removal, inventory control, emergency AC power, containment control, or reactivity control systems would have been available prior to the PMH affecting the site. The finding screened as Green because none of the attributes in the checklists were adversely impacted.
No cross cutting aspects were assigned to the finding. The finding does not represent current licensee performance because the degraded and missing penetrations have existed since original construction of the plant.
Enforcement:
10 CFR 50, Appendix B, Criterion III, Design Controls, requires, in part, that measures shall be established to assure that applicable regulatory requirements and the design basis are correctly translated into specifications, drawings, procedures and instructions. These measures shall include provisions to assure that appropriate quality standards are specified and included in design documents and that deviations from such standards are controlled. The licensees design basis does not allow for any external leakage into safety-related buildings during a PMH. Unit 1 UFSAR section 3.4.4, states in part, that All external building penetrations are waterproofed and/or flood protected to preclude the failure of safety related system or component due to external flooding. Unit 2 UFSAR, section 2.4.2.2.b states, in part, Flood protection criteria is established at elevation 19.5 feet MLW whereby exterior doors and penetrations which lead to areas containing safety related equipment are made watertight through use of boots, waterstops and waterproofing. Unit 1, licensee drawing 8770-B-328, sheet 4A, Revision 6, specifies that all ductbank entry into safety related buildings at or below the PMH flood level shall be sealed. Unit 2 drawing 2998-C-348, sheet 1, Revision 5, specifies that all conduit entries into safety related buildings at or below grade shall be sealed.
Contrary to the above, the licensee did not assure that deviations from the design basis were controlled when below grade conduit penetrations were originally installed. Additionally, other seals that were originally installed were not maintained.
Specifically, in September 2012, the licensee identified Unit 1 and 2 degraded and missing conduit penetrations seals that had not been originally installed or maintained as required by the design basis. As a result, during PMH conditions, water in-leakage through the penetrations would result in the flooding of the -0.5 foot elevation of both units RAB. The flooding could have resulted in the loss of both Unit 1 boric acid makeup pumps. Because the licensee entered the issue into their corrective action program as ARs 1804496 and 1800822, and the finding is of very low safety significance (Green), this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy: NCV 05000335, 389/2013002-02, Failure to Ensure Reactor Auxiliary Building Penetrations were Adequately Flood Protected.
.3 (Closed) LER 05000335/2012-004-00, Seismically Qualified Refueling Water Tank
Aligned to Non-Seismic Piping On August 1, 2012, the licensee determined that opening a manual boundary valve between the safety-related and seismically qualified refueling water tank (RWT) and the non-safety and non-seismically qualified purification system in Modes 1 - 4 rendered the RWT inoperable. The cause of the event was the incorrect application of the use of manual operator actions in maintaining operability of the RWT when in this configuration. The inspectors reviewed the LER and AR 1756212 that documented the event. Additional information and the regulatory significance of this issue are documented in section 4OA2.3. This LER is closed.
.4 (Closed) LER 05000389/2012-003-00, Inadvertent Trip of 2B3 4.16 kv Switchgear
On October 7, 2012, Unit 2 was defueled; the A electrical train was protected and providing spent fuel pool cooling. The licensee was executing planned B electrical train work activities. The 2B3 4.16kv essential bus was not required to be operable.
During the process of racking in the 2B component cooling water (CCW) pump breaker, plant personnel inadvertently caused the 2B3 4.16kv essential bus to de-energize. Prior to the event, the B EDG was supplying power to the bus and as a result of the event, the EDGs output breaker immediately tripped opened and the EDG transferred to emergency mode. Throughout the event, the 2A EDG and all A train equipment remained operable.
The licensees apparent cause evaluation found that the reason the 4.16kv bus inadvertently de-energized was a result of plant personnel shorting out a set of differential relay terminals located on the inside of the door to the 2B CCW pump breaker. This relay actuation caused a differential current lockout on the electrical bus. The evaluation concluded that the plant personnel were not fully aware of the risk significance associated with the unprotected differential relay terminals as a result of not having performed an adequate work assessment of the immediate work area as required by licensees conduct of maintenance procedure prior to starting the work. Due to ongoing outage work, scaffolding and other equipment was in the immediate area which resulted in a small work space available to perform the planned activity. The reduced work space could have been better assessed and other precautions implemented prior to performing the planned work. Corrective actions included a bulletin providing a brief on working in areas of limited space while emphasizing inspecting for nearby objects prior to beginning work.
The inspectors reviewed the LER and AR 1810742 documenting this event, and interviewed licensee personnel associated with the event and investigation. The inspectors checked the accuracy and completeness of the LER and the appropriateness of the licensees corrective actions. The inspectors reviewed the licensees CAP data base and did not identify any other similar issues relating to an inadequate pre-job site risk assessment. The inspectors determined that the licensees failure to perform an adequate risk assessment of the job site as required by licensees conduct of maintenance procedure prior to starting the job activity was a performance deficiency (PD) that was not a violation of NRC requirements.
The inspectors screened the performance deficiency in accordance with Inspection Manual Chapter (IMC) 0612, Appendix B, Issue Screening, dated September 7, 2012, and determined that, in this case, the performance deficiency was minor. The PD was minor because it did not cause any required safety related equipment to become inoperable as this job was planned well in advance and was scheduled to occur during a time that the B electrical train was not required to be operable. The inspectors concluded that the PD was not a precursor to a significant event, did not have the potential to lead to a more significant safety concern, was not related to a performance indicator that would have caused the performance indicator to exceed a threshold, and did not adversely affect any of the cornerstone objectives listed at the end of manual chapter 0612 Appendix B. No findings were identified. This LER is closed.
.5 Personnel Performance During Unplanned Plant Operations
Unit 1 Automatic Reactor Trip
a. Inspection Scope
The inspectors observed personnel performance immediately following a Unit 1 automatic reactor from 100 percent RTP that occurred on March 12. The inspectors reviewed plant status, equipment and personnel performance associated with the trip.
The trip was initiated by the closure of the 1B main steam isolation valve due to a stem/disc separation. The inspectors reviewed post-trip actions that placed the plant in a safe condition. The inspectors reviewed the licensees post trip report which included a record of plant transient parameters and operator logs. Additionally, the inspectors interviewed operators, attended post-trip review meetings, and verified emergency operating procedure compliance. The inspectors discussed the trip with operations, engineering, and licensee management personnel to gain an understanding of the event and assess follow-up actions to provide input to the NRC decision making process regarding the need for a special or augmented NRC inspection.
b. Findings
No findings were identified
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 activities to ensure that the activities were consistent with the 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 Independent Spent Fuel Storage Installation (ISFSI) Inspections (IP 60855.1)
a. Inspection Scope
The inspectors reviewed reported changes made to the licensees procedures and programs for the ISFSI to verify the changes made were consistent with the license and Certificate of Compliance (CoC) and did not reduce the effectiveness of the program. The inspectors, through direct observation and independent evaluation, verified cask loading activities were performed in a safe manner and in compliance with approved procedures. Based on direct observation and review of selected records, the inspectors verified the licensee had properly identified each fuel assembly and insert placed in the ISFSI, had recorded the parameters and characteristics of each fuel assembly and insert, and had maintained a record of each as a controlled document. The inspectors observed activities associated with the transport and storage of casks, loading of spent fuel in casks, vacuum drying and seal welding activities, and the heavy lifts to remove the casks from the spent fuel pool and place it in the cask handling facility. Documents reviewed are listed in the
.
b. Findings

.3 (Closed) NRC Temporary Instruction (TI) 2515/187, Inspection of Near-Term Task
Force Recommendation 2.3 Flooding Walkdowns
a. Inspection Scope
The inspectors verified that licensees walkdown packages for areas including Unit 1 east side of auxiliary building 19.5 foot elevation, Unit 2 east side of auxiliary building 19.5 foot elevation, and west side of Unit 2 auxiliary building 19.5 foot elevation contained the elements as specified in NEI 12-07 Walkdown Guidance document.
The inspectors accompanied the licensee on their walkdowns and verified that the licensee confirmed the following flood protection features using visual observation or by review of other documents.
- Unit 2 auxiliary building east wall door flooding stop logs staged and ready for use
- All exterior wall penetrations of Unit 1 and Unit 2 auxiliary building were properly sealed
- Various Unit 1 and Unit 2 electrical wire way manhole inspections for penetration seal conditions The inspectors independently performed their walkdown and verified that the following flood protection features were in place:
- Unit 1 and Unit 2 auxiliary building perimeter walls properly sealed and associated stop logs staged and ready for usage on Unit 2
- Selected one electrical wire way manhole on each unit to verify dewatering capability and wall cable penetration seal conditions The inspectors verified that noncompliances with current licensing requirements, and issues identified in accordance with the 10 CFR 50.54(f) letter, Item 2.g of Enclosure 4, were entered into the licensee's corrective action program. In addition, issues identified in response to Item 2.g that could challenge risk significant equipment and the licensees ability to mitigate the consequences will be subject to additional NRC evaluation.
b. Findings
No findings were identified.
