SUMMARY OF FINDINGS
IRs 05000413/2011-002, 05000414/2011-002, 05000413/2011-501, 05000414/2011-
501; 1/1/2011 - 3/31/2011; Catawba Nuclear Station, Units 1 and 2; Emergency Action Level and Emergency Plan Changes The report covered a three month period of inspection by two resident inspectors and two region-based inspectors. One Green finding was identified which was determined to be a violation of NRC requirements. The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609,
"Significance Determination Process" (SDP). The cross-cutting aspects were determined using IMC 0310, "Components Within The Cross-Cutting Areas." Findings for which the SDP does not apply may be Green or be assigned a severity level after NRC management review. The NRC's program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, "Reactor Oversight Process."
Cornerstone: Emergency Preparedness
- Green: An NRC-identified NCV of 10 CFR 50.54(q) with two examples was identified for failing to maintain emergency plans that meet the requirements of 10 CFR 50.47(b)(4). The licensee failed to revise the Emergency Action Level (EAL) basis which potentially impacted the licensee's ability to accurately and timely classify emergency conditions. The licensee has entered this issue into their corrective action program as Problem Investigation Program report (PIP) C-11-2304.
The failure to revise the EAL basis document as required by the Catawba Emergency Plan was a performance deficiency (PD). The PD was more than minor because if left uncorrected, the potential to incorrectly classify events associated with the fission product barrier matrix or security-event classification scheme within the brief time available would lead to a more significant safety concern. This finding was associated with the risk significant planning standard (RSPS) 10 CFR 50.47(b)(4). The finding was determined to be of very low safety significance (Green) because it did not result in a loss or degradation of a RSPS function. The cause of this finding was directly related to the cross-cutting aspect of complete and accurate procedures in the Resources component of the Human Performance area because the procedure used to evaluate EAL changes, EPFAM Section 3.10, did not include a requirement to change the EAL basis document as appropriate. H.2(c) (Section 1EP4) One violation of very low safety significance (Green), which was identified by the licensee, has been reviewed by the inspectors. Corrective actions taken or planned by the licensee have been entered into the licensee's corrective action program. This violation and corrective action tracking number are listed in Section 4OA7 of this report.
REPORT DETAILS
Summary of Plant Status
Unit 1 operated at or near 100 percent Rated Thermal Power (RTP) for the entire inspection period.
Unit 2 operated at or near 100 percent RTP until February 5, 2011, when power was reduced to 88 percent RTP for control valve movement testing. Power was returned to 100 percent RTP on February 6, 2011, where it remained for the rest of the inspection period.
REACTOR SAFETY
Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity
1R01 Adverse Weather Protection
a. Inspection Scope
Adverse Weather Conditions: The inspectors reviewed the licensee's severe weather actions following a tornado watch issued on February 28, 2011. This included a review of actions required by RP/0/A/5000/007, Natural Disaster and Earthquake, enclosure 4.1, and the Hazard Barrier Control Form for the Nuclear Service Water (RN) excavation activities to verify that the design features and implementation of the licensee's procedures protected mitigating systems from adverse weather effects. Documents reviewed are listed in the Attachment.
b. Findings
No findings were identified.
1R04 Equipment Alignment
a. Inspection Scope
Partial Walkdowns: The inspectors performed three partial system walkdowns during the activities listed below to assess the operability of redundant or diverse trains and components when safety-related equipment was inoperable. The inspectors attempted to identify any discrepancies that could impact the function of the system and, therefore, potentially increased risk. The inspectors reviewed applicable operating procedures and walked down system components, selected breakers, valves, and support equipment to determine if they were in the correct position to support system operation. The inspectors reviewed protected equipment sheets, maintenance plans, and system drawings to determine if the licensee had properly identified and resolved equipment alignment problems that could cause initiating events or impact the capability of mitigating systems or barriers, and entered them into the corrective action program. Documents reviewed are listed in the Attachment.
- Train 'A' Controlled Area Chilled Water and Ventilation while the 'B' train was inoperable due to planned electrical configuration changes
- Unit 1 Motor driven auxiliary feedwater trains while the turbine driven auxiliary feedwater pump was inoperable due to preventive maintenance
- Unit 1 'A' Diesel Generator (DG) while the 'B' DG was inoperable due to a failed surveillance Complete System Walkdown: The inspectors conducted one detailed walkdown/review of the Unit 2 Residual Heat Removal System. The inspectors used licensee procedures and licensing and design documents to verify that the system (i.e., pump, valve, and electrical) alignment was correct; valves and pumps did not exhibit leakage that would impact their function; major portions of the system and components were correctly labeled; hangers and supports were correctly installed and functional; and essential support systems were operational. In addition, pending design and equipment issues were reviewed to determine if the identified deficiencies significantly impacted the system's functions. Items included in this review were: the operator workaround list; the temporary modification list; and outstanding maintenance work requests/work orders. A review of open PIP reports was also performed to verify that the licensee had appropriately characterized and prioritized safety-related equipment problems for resolution in the corrective action program. Documents reviewed are listed in the Attachment.

Cornerstone:
Emergency Preparedness 1EP2 Alert and Notification System Testing
a. Inspection Scope
The inspectors evaluated the adequacy of licensee's methods for testing the Alert and Notification System (ANS) in accordance with NRC Inspection Procedure 71114, Attachment 02, Alert and Notification System Evaluation. The applicable planning standard, 10 CFR 50.47(b)(5), and its related requirements, 10 CFR 50, Appendix E, Section IV.D, were used as reference criteria. The criteria contained in NUREG-0654, Criteria for Preparation and Evaluation of Radiological Emergency Response Plans and Preparedness in Support of Nuclear Power Plants, Revision 1, was also used as a reference. Documents reviewed are listed in the Attachment. This inspection activity satisfied one sample.
b. Findings
No findings were identified.
1EP3 Emergency Preparedness Organization Staffing and Augmentation System
a. Inspection Scope
The inspectors reviewed the licensee's Emergency Response Organization (ERO) augmentation staffing requirements and process for notifying the ERO to ensure the readiness of key staff for responding to an event and timely facility activation. The qualification records of key position ERO personnel were reviewed to ensure all ERO qualifications were current. A sample of problems identified from augmentation drills or system tests performed since the last inspection were reviewed to assess the effectiveness of corrective actions. The inspection was conducted in accordance with NRC Inspection Procedure 71114, Attachment 03, Emergency Response Organization Staffing and Augmentation System. The applicable planning standard, 10 CFR 50.47(b)(2), and its related requirements, 10 CFR 50, Appendix E, were used as reference criteria. Documents reviewed are listed in the Attachment. This inspection activity satisfied one sample.
b. Findings
No findings were identified.
1EP4 Emergency Action Level and Emergency Plan Changes
a. Inspection Scope
No changes have been made to revision 30 of the Radiological Emergency Response Plan since the last NRC inspection of this program area. However, changes were made to the Emergency Action Levels (EALs) and other implementing procedures based on the licensee's determination, in accordance with 10 CFR 50.54(q), that there was no decrease in the effectiveness and the Plan continued to meet the requirements of 10 CFR 50.47(b) and Appendix E to 10 CFR Part 50 except as noted below. The inspectors conducted a review of the EAL changes and a sample of the implementing procedure changes made between March 1, 2010, and February 28, 2011, to evaluate for potential decreases in effectiveness of the Plan. However, this review was not documented in a Safety Evaluation Report and does not constitute formal NRC approval of the changes. Therefore, these changes remain subject to future NRC inspection in their entirety. The inspection was conducted in accordance with NRC Inspection Procedure 71114, Attachment 04, Emergency Action Level and Emergency Plan Changes. The applicable planning standard, 10 CFR 50.47(b)(4), and its related requirements, 10 CFR 50, Appendix E, were used as reference criteria. Documents reviewed are listed in the Attachment. This inspection activity satisfied one inspection sample.
b. Findings
Introduction:
An NRC-identified NCV of 10 CFR 50.54(q) with two examples was identified for failing to maintain emergency plans that meet the requirements of 10 CFR 50.47(b)(4). The licensee failed to revise the EAL basis which potentially impacted the licensee's ability to accurately and timely classify emergency conditions.
Description:
On March 31, 2010, and October 11, 2010, the licensee implemented revisions 22 and 24, respectively, of procedure RP/0/A/5000/001, Classification of Emergency. Revision 22 addressed containment barrier matrix EAL changes as a result of a plant modification to containment spray system operation under a NRC approved license amendment. Revision 24 incorporated changes to security event EALs per NRC Bulletin 2005-02, Emergency Preparedness and Response Actions For Security-based Events. Both revisions added or modified conditions requiring emergency classification actions. The licensee evaluated these revisions using the 10 CFR 50.54(q) process using the Emergency Planning Functional Area Manual (EPFAM), Section 3.10, 10 CFR 50.54(q) Evaluations, Rev. 11, and determined there was no decrease in plan effectiveness. Catawba Emergency Plan (CEP) section D.2 stated, in part, that initiating conditions and their corresponding EALs were contained in the basis document contained in the CEP section D.4. This basis section was not revised to address the new EAL classification scheme requirements. Using the existing basis, a potential loss of containment barrier could be inappropriately evaluated, resulting in an incorrect emergency action level classification. In the case of security EALs, there was no longer a one-to-one correspondence between EALs and basis information. During an event, operators have a very short time to evaluate an unfolding situation and use the EAL tables to classify an event but do refer to the basis document if clarification is needed.
Since time is of the essence, particularly early in an event, outside technical assistance may not be available to resolve the apparent differences between EAL and bases. Timely and accurate classification is critical to meet this risk significant emergency planning standard. Licensee corrective actions included changing the Emergency Plan bases document and to perform appropriate causal analysis to develop other corrective actions.
Analysis:
The failure to revise the EAL basis document as required by the Catawba Emergency Plan was a PD. The PD was more than minor because if left uncorrected, the potential to incorrectly classify events associated with the fission product barrier matrix or security-event classification scheme within the brief time available would lead to a more significant safety concern. This finding was associated with the Risk Significant Planning Standard, 10 CFR 50.47(b)(4). Using Emergency Preparedness Significance Determination Process, IMC 0609, Appendix B, Sheet 1, Failure to Comply, the finding was determined to be of very low safety significance (Green) because it did not result in a loss or degradation of a RSPS function. The cause of this finding was directly related to the cross-cutting aspect of complete and accurate procedures in the Resources component of the Human Performance area because the procedure used to evaluate EAL changes, EPFAM Section 3.10, did not include a requirement to change the EAL basis document as appropriate. H.2(c)
Enforcement:
10 CFR 50.54(q) stated, in part, that a holder of a nuclear power reactor operating license under this part shall follow and maintain in effect emergency plans which meet the standards in 50.47(b) and the requirements in Appendix E of this part. 10 CFR 50.47(b)(4) stated, in part, that a standard emergency classification and action level scheme, the basis of which include facility system and effluent parameters, is in use by the nuclear facility licensee. Contrary to the above, since March 31, 2010, and October 11, 2010, respectively, the licensee failed to maintain in effect an emergency plan when changes were made to the emergency classification and action level schemes. Because the violation was entered into the licensee's corrective action program as PIP C-11-2304, it is being treated as a non-cited violation consistent with Section 2.3.2 of the Enforcement Policy: NCV 05000413, 414/2011002-01, Failure to Update Bases For EAL Changes.
1EP5 Correction of Emergency Preparedness Weaknesses and Deficiencies
a. Inspection Scope
The inspectors reviewed the corrective actions identified through the Emergency Preparedness program to determine the significance of the issues and to determine if repeat problems were occurring. The facility's self-assessments and audits were reviewed to assess the licensee's ability to be self-critical, thus avoiding complacency and degradation of their emergency preparedness program. In addition, the inspectors reviewed licensee self-assessments and audits to assess the completeness and effectiveness of all emergency preparedness-related corrective actions. The inspection was conducted in accordance with NRC Inspection Procedure 71114, Attachment 05, Correction of Emergency Preparedness Weaknesses. The applicable planning standard, 10 CFR 50.47(b)(14), and its related 10 CFR 50, Appendix E requirements were used as reference criteria. Documents reviewed are listed in the Attachment. This inspection activity satisfied one inspection sample for the correction of emergency preparedness weaknesses on a biennial basis.
b. Findings
No findings were identified.
1EP6 Drill Evaluation
a. Inspection Scope
The inspectors observed and evaluated the licensee's emergency planning performance during a drill conducted on February 10, 2011. The inspectors reviewed licensee activities that occurred in the Simulator and the Technical Support Center during a simulated event. The inspectors' assessment focused on the timeliness and accuracy of the event classification, notification of offsite agencies and the overall response of the personnel involved in the drill from an operations and emergency planning perspective. The performance of the Emergency Response Organization was evaluated against applicable licensee procedures and regulatory requirements. The inspectors attended the post-exercise critique for the drill to evaluate the licensee's self-assessment process for identifying potential deficiencies relating to failures in classification and notification.
The inspectors reviewed the completed critique developed by the licensee documenting the overall performance of the Emergency Response Organization.
b. Findings
No findings were identified.
OTHER ACTIVITIES
4OA1 Performance Indicator Verification
a. Inspection Scope
The inspectors sampled licensee data to confirm the accuracy of reported performance indicator (PI) data for the nine indicators during periods listed below. To determine the accuracy of the reported PI elements, the reviewed data was assessed against PI definitions and guidance contained in Nuclear Energy Institute 99-02, Regulatory Assessment Indicator Guideline, Rev. 5. Documents reviewed are listed in the Attachment.
Cornerstone:
- Unplanned Scrams with Complications, Unit 1 & 2
Cornerstone:
- Cooling Water Systems, Unit 1 & 2
Cornerstone:
- Reactor Coolant System Activity, Unit 1 & 2 The inspectors reviewed the licensee's procedures and methods for compiling and reporting the PIs including the Reactor Oversight Program Mitigating Systems Performance Indicator Basis Document for Catawba. The inspectors reviewed the raw data for the PIs listed above for the period of January 1, 2010, through December 31, 2010. The inspectors also independently screened TS Action Item Logs, selected control room logs, work orders and surveillance procedures, and maintenance rule failure determinations to determine if unavailability/unreliability hours were properly reported. The inspectors compared the licensee's raw data against the graphical representations and specific values contained on the NRC's public web page for 2010. The inspectors also reviewed the past history of PIPs for systems affecting the Mitigating Systems Performance Indicators listed above for any that might have affected the reported values. The inspectors reviewed Nuclear Energy Institute 99-02, Regulatory Assessment Performance Indicator Guideline, to verify that industry reporting guidelines were applied. Documents reviewed are listed in the Attachment.
Cornerstone:
- Emergency Response Organization Drill/Exercise Performance (DEP)
- Emergency Response Organization Readiness (ERO)
- Alert and Notification System Reliability (ANS)
The inspection was conducted in accordance with NRC IP 71151, "Performance Indicator Verification." For the specified review period, the inspectors examined data reported to the NRC, procedural guidance for reporting PI information, and records used by the licensee to identify potential PI occurrences. The inspectors verified the accuracy of the PI for ERO drill and exercise performance through review of a sample of drill and event records. The inspectors reviewed selected training records to verify the accuracy of the PI for ERO drill participation for personnel assigned to key positions in the ERO. The inspector verified the accuracy of the PI for alert and notification system reliability through review of a sample of the licensee's records of periodic system tests. The inspector also interviewed the licensee personnel who were responsible for collecting and evaluating the PI data. Documents reviewed are listed in the Attachment.
b. Findings
No findings were identified.
4OA2 Problem Identification and Resolution
.1 Daily Review
As required by Inspection Procedure 71152, Problem Identification and Resolution, and in order to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed screening of items entered into the licensee's corrective action program. This was accomplished by reviewing copies of PIPs, attending selected daily Site Direction and PIP screening meetings, and accessing the licensee's computerized database.
.2 Focused Review
a. Inspection Scope
Within the mitigating systems cornerstone, the inspectors performed an in-depth review of PIP C-10-3298, 1B DG jacket water keep warm pump tripped. Documents reviewed are listed in the Attachment.
The inspectors reviewed the actions taken to determine if the licensee had adequately addressed the following attributes:
- Complete, accurate and timely identification of the problem
- Evaluation and disposition of operability and reportability issues
- Consideration of previous failures, extent of condition, generic or common cause implications
- Prioritization and resolution of the issue commensurate with safety significance
- Identification of the root cause and contributing causes of the problem
- Identification and implementation of corrective actions commensurate with the safety significance of the issue
b. Findings
No findings were identified.
4OA3 Followup of Events and Notices of Enforcement Discretion (NOED)
.1 Response to Plant Events
a. Inspection Scope
The inspectors evaluated the licensee event, "Unit 2 1A reactor coolant pump seal injection line flow element fitting leak," for plant status and mitigating actions. As appropriate, the inspectors: (1) observed plant parameters and status, including mitigating systems/trains and fission product barriers; (2) determined alarms/conditions preceding or indicating the event; and (3) evaluated performance of plant systems and licensee actions. Documents reviewed are listed in the Attachment.
b. Findings
No findings were identified.
.2 (Closed) Licensee Event Report (LER) 05000414/2010-002-0:
Technical Specification Violation Involving Mode Change with Inoperable Auxiliary Feedwater System Train Due to Closed Pump Discharge Valves On October 17, 2010, during startup following the completion of a refueling outage, Unit 2 entered Mode 4 with the required motor driven train of the Auxiliary Feedwater (AFW) system inoperable due to both the A and B train AFW pump discharge valves being closed. The discharge valves were left closed following operation of the AFW pumps while in Mode 5. TS 3.7.5 required one motor driven train of AFW with manual actuation operable for Mode 4 operation. The TS bases did not distinguish system alignment between manual and automatic actuation even though the operators had the capability and procedural guidance to manually open the discharge valves from the control room.
Therefore, the discharge valves being out of their normal alignment resulted in the A and B AFW trains being inoperable, and resulted in a violation of TS 3.0.4 when the unit entered Mode 4. The discharge valves were opened approximately 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> after entering Mode 4. The LER and supporting documents, which included completed and planned corrective actions, were reviewed by the inspectors. Due to the fact that both motor driven trains of AFW were available for manual actuation of AFW, this failure to comply with TS 3.0.4 constituted a violation of minor safety significance that was not subject to enforcement action in accordance with the NRC's Enforcement Policy. The licensee entered this issue into their corrective action program as PIP C-10-7022.
.3 NOED Review
a. Inspection Scope
On February 23, the 1B DG was declared inoperable due to load swings observed during the TS 24-hour loaded surveillance test. TS 3.8.1, AC Sources, Action B.4 was entered which required the DG to be restored to operable in 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or place the Unit in Mode 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> 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 />. Additionally, 72-hour action statements were also entered for the Nuclear Service Water System (TS 3.7.8), Auxiliary Feedwater System (TS 3.7.5), and Containment Spray System (TS 3.6.6) due to various system dependencies.
The licensee determined that the load swings were due to a defective mechanical governor; however, governor replacement and post-maintenance testing could not be completed within the TS 3.8.1 72-hour action statement. On February 25, the licensee requested enforcement discretion for an additional 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> for TS 3.8.1 which allowed governor replacement and post-maintenance testing to preclude a plant shutdown of Unit 1. The NRC verbally granted the NOED at 4:55 p.m., on February 25. The licensee returned the 1B DG and support systems to an operable status on February 27 at 2:54 p.m., which was within the completion time approved in the NOED.
b. Findings
Introduction:
An unresolved item (URI) was identified for NOED 11-2-002.
Description:
The inspectors reviewed NOED 11-2-002 and related documents to determine the accuracy and consistency with the licensee's assertions and implementation of the licensee's compensatory measures and commitments which included deferring non-essential surveillances and other maintenance activities on the 1A DG, the turbine-driven AFW pump, the Standby Shutdown System and switchyard, and posting a dedicated operator available to throttle key AFW valves that supply flow to the steam generators. Additional inspection is required to conduct a review of the LER, root cause, and planned corrective actions. This URI is identified as URI 05000413/2011002-02, Follow-up for NOED 11-2-002.
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 that the 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.
4OA6 Meetings, Including Exit
Exit Meeting Summary
On April 6, 2011, the resident inspectors presented the inspection results to Mr. Steve Putnam, Safety Assurance Manager, and other members of licensee management, who acknowledged the findings. The inspectors confirmed that any proprietary information provided or examined during the inspection period had been returned.
4OA7 Licensee-Identified Violations
The following violation of very low safety significance (Green) was identified by the licensee and is a violation of NRC requirements which met the criteria of the NRC Enforcement Policy, for being dispositioned as a Non-Cited Violation.
- 10 CFR 50.65(a)(4) states, in part, that before performing maintenance activities, the licensee shall assess and manage the increase in risk that may result from the proposed maintenance activities. Contrary to the above, on January 26, 2011, the licensee did not assess and manage an increase in risk when the "A" Station Air compressor was removed from service for eight hours while the "E" Instrument Air Dryer was tagged out of service. The resultant risk management profile with these two activities occurring simultaneously increased from Green to Yellow. The conflict was not scheduled and the Yellow risk profile was not planned; therefore, the appropriate risk management actions were not implemented. The inspectors determined that the violation was not greater than very low safety significance (Green) because the increased risk was qualitative, with no quantitative increase in the Incremental Core Damage Probability. The issue is documented in the licensee's corrective action program as PIP C-11-0627.
