SUMMARY OF FINDINGS
IR 05000413/2012-004, 05000414/2012-004; 7/1/2012 - 9/30/2012; Catawba Nuclear Station,
Units 1 and 2; Mitigating Systems The report covered a three-month period of inspection by the resident inspectors and two Region-based reactor inspectors. Two Green non-cited violations (NCVs) were identified. The significance of inspection findings are indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP) dated June 2, 2011. Cross-cutting aspects are determined using IMC 0310, Components Within the Cross-Cutting Areas dated October 28, 2011. All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy dated June 12, 2012. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process revision 4.
Cornerstone: Mitigating Systems
- Green: An NRC-identified Green non-cited violation (NCV) of the Unit 1 and 2 Facility Operating Licenses, Condition 2.C.5, Fire Protection Program, was identified for failure to implement and maintain all provisions of the approved fire protection program. The inspectors identified gaps in the emergency switchgear room (ESR) hatch covers separating two fire areas containing redundant safe shutdown equipment which were not evaluated. The licensee placed the issue into the corrective action program and implemented fire watches and prohibited storage of transient combustibles in the area.
The inspectors determined the gaps in the ESR hatch covers was a performance deficiency (PD). The inspectors determined that the PD was more than minor because it was associated with the Mitigating System Cornerstone attribute of Protection against External Factors (fire) and adversely affected the cornerstone objective in that there was no reasonable assurance the gaps in the hatch covers would prevent fire propagation across the 3-hour fire rated barrier. The inspectors determined the finding was of very low safety significance (Green). The cause of this finding was related to the cross cutting-aspect to thoroughly evaluate problems such that the resolutions address causes and extent of condition as described in the corrective action program component of the Problem Identification and Resolution cross-cutting area. P.1(c) (Section 1R05)
- Green: An NRC-identified non-cited violation (NCV) of 10 CFR 55.49, Integrity of examinations and tests, was identified for the licensees failure to adhere to examination procedure standards that allow no more than 50 percent scenario overlap between examinations. The licensee subsequently revised the 2012 annual operating examination to preclude the scenario overlap issue that would have occurred and entered the issue in their corrective action program as PIP C-12-06949 and PIP C-12-06950.
This performance deficiency was more than minor because it was associated with the Human Performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective in that the failure to adhere to examination overlap standards adversely affected the quality of the administration of the operating exams.
Using the Licensed Operator Requalification Significance Determination Process, this finding was determined to be of very low safety significance (Green) because no actual compromise of the examinations occurred. The cause of the finding was related to the cross-cutting aspect of procedures of the resources component of the cross-cutting area of Human Performance. H.2(c) (Section 1R11)
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 licensees corrective action program. This violation and corrective action tracking number are listed in section 4OA7.

Cornerstones: Initiating Events, Mitigating Systems, Barrier Integrity
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 performed walkdowns 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.

1R05 Fire Protection
a. Inspection Scope
Fire Protection Walkdowns: The inspectors walked down accessible portions of the four plant areas listed below to assess the licensees control of transient combustible material and ignition sources, fire detection and suppression capabilities, fire barriers, and any related compensatory measures. The inspectors observed the fire protection suppression and detection equipment to determine whether any conditions or deficiencies existed which could impair the operability of that equipment. The inspectors selected the areas based on a review of the licensees safe shutdown analysis probabilistic risk assessment and sensitivity studies for fire-related core damage accident sequences. Documents reviewed are listed in the Attachment.
- Unit 2 Electrical Penetration Room 594 Elevation
- Unit 1 A Essential Switchgear Room 577 Elevation
- Unit 2 Electrical Penetration Room 560 Elevation
- Unit 1 and 2 Control Room
b. Findings
Introduction:
An NRC-identified Green non-cited violation (NCV) of the Unit 1 and 2 Facility Operating Licenses, Condition 2.C.5, Fire Protection Program, was identified for failure to implement and maintain all provisions of the approved fire protection program.
The inspectors identified gaps in the emergency switchgear room (ESR) hatch covers separating two fire areas containing redundant safe shutdown equipment which were not evaluated.
Description:
During fire protection walkdowns in the Unit 1 and 2 A train essential switchgear rooms (ESRs) on the 577 elevation, the inspectors identified gaps in hatch covers used to maintain the 3-hour rated barrier between the A and B ESRs. The hatch covers were not 3-hour fire rated, however, the licensee received an exemption in Safety Evaluation Report (SER) Supplement 3 on the basis that hatch covers would fit tightly and prevent vertical fire propagation across the barrier. The gaps that were identified, totaling approximately one square inch, would allow hot gasses to pass from the B ESR into the A ESR. Because the licensee had not evaluated these gaps there was no reasonable assurance that the hatch covers would prevent vertical fire propagation across the 3-hour fire barrier. The licensee initially identified this condition in 2007 and initiated PIP C-07-0872. However, the licensee failed to evaluate the gaps and closed the PIP based on the hatch cover exemption in the SER. Immediate corrective actions included placing signage on the covers prohibiting storage of transient combustibles in the area and establishing a twice a shift fire watch to be conducted by operators on rounds.
Analysis:
The inspectors determined the gaps in the ESR hatch covers was a PD. The inspectors determined that the PD was more than minor because it was associated with the Mitigating System Cornerstone attribute of Protection against External Factors (fire),and adversely affected the cornerstone objective in that there was no reasonable assurance the gaps in the hatch covers would prevent fire propagation across the 3-hour fire rated barrier. Using IMC 0609, Significance Determination Process, Attachment 0609.04, Phase 1 Initial Screening and Characterization of Findings, Table 3b, the inspectors determined the finding degraded the fire protection defense-in-depth strategies. The inspectors reviewed IMC 0609, Appendix F and determined that the finding impacted the Fire Confinement Finding Category. Based on review of IMC 0609, Appendix F, Attachment 2, Degradation Rating Guidance Specific to Various Fire Protection Program Elements, the inspectors determined that the degradation rating was low based on the size of the gap. As a result, this finding was determined to be of very low safety significance (Green) based on the guidance in IMC 0609, Appendix F,
thoroughly evaluate problems such that the resolutions address causes and extent of condition as described in the corrective action program component of the Problem Identification and Resolution cross-cutting area because this issue was previously identified however corrective action was not taken for resolution. P.1(c)
Enforcement:
Unit 1 and 2 Facility Operating Licenses, Condition 2.C.5, required that the licensee shall implement and maintain in effect all provisions of the approved fire protection program as described in Section 9.5.1 of the Updated Final Safety Analysis Report (UFSAR) as amended and approved in the SER through Supplement 5. SER section 9.5.1.5, Building Design and SER section 9.5.1.7, Switchgear Room, stated in part, that floor/ceiling assemblies shall have a 3-hour fire rating and that the switchgear rooms are separated from each other and the remainder of the plant by a 3-hour fire barrier. Contrary to the above, from initial plant construction until September 2012, all provisions of the approved fire protection program as described in Section 9.5.1 of the Updated Final Safety Analysis Report (UFSAR) as amended and approved in the SER through Supplement 5 were not maintained in effect. Gaps between hatch covers separating the Unit 1 and 2 A and B ESRs, which had not been evaluated, represented a degradation of the 3-hour fire barrier separation requirements. Since the finding was of very low safety significance and has been entered into the licensees corrective action program as PIP C-12-5834, this violation was treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy, and is identified as NCV 05000413/414/2012004-01, Inadequate 3 hour3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> fire barrier between essential switchgear rooms.
1R06 Flood Protection Measures
a. Inspection Scope
The inspectors entered two conduit manholes: Conduit CMH-8B and CMH-9B to verify that the cables were not submerged, that the cables were not damaged or degraded, and that the sump pumps were functioning properly. Documents reviewed are listed in the Attachment.
b. Findings
No findings were identified.
1R11 Licensed Operator Requalification (LOR) Program and Licensed Operator Performance
.1 Quarterly Resident Inspector LOR Activity Review
a. Inspection Scope
The inspectors observed Simulator Exercise S-71 to assess the performance of licensed operators during a license operator requalification simulator training session. The exercise included a feed water pump tripping causing a turbine runback as well as a rod ejection requiring a reactor trip and manual safety injection. The inspectors assessed overall crew performance, clarity and formality of communications, use of procedures, alarm response, control board manipulations, group dynamics and supervisory oversight. The inspectors observed the post-exercise critique to determine whether the licensee identified deficiencies and discrepancies that occurred during the simulator training. Documents reviewed are listed in the Attachment.
b. Findings
No findings were identified.
.2 Quarterly Resident Inspector Licensed Operator Performance Review
a. Inspection Scope
The inspectors observed operators in the main control room and assessed their performance during Unit 1 moderator temperature coefficient measurements, a Unit 1 dilution, and preparations for a unit shutdown per TS 3.0.3. Documents reviewed are listed in the Attachment.
b. Findings
No findings were identified.
.3 Biennial Review by Regional Specialist
a. Inspection Scope
The inspectors reviewed documentation, interviewed licensee personnel, and observed the administration of operating tests associated with the licensees operator requalification program to assess the effectiveness of the facility licensee in implementing requalification requirements identified in 10 CFR Part 55, Operators Licenses. Evaluations were also performed to determine if the licensee effectively implemented operator requalification guidelines established in NUREG-1021, Operator Licensing Examination Standards for Power Reactors, and Inspection Procedure (IP)71111.11, Licensed Operator Requalification Program. The inspectors also evaluated the licensees simulation facility for adequacy for use in operator licensing examinations using ANSI/ANS-3.5-1998, American National Standard for Nuclear Power Plant Simulators for use in Operator Training and Examination. The inspectors observed four crews during the performance of the operating tests. Documentation reviewed included written examinations, Job Performance Measures (JPMs), simulator scenarios, licensee procedures, on-shift records, simulator modification request records, simulator performance test records, operator feedback records, licensed operator qualification records, remediation plans, watchstanding records, and medical records. The records were inspected using the criteria listed in IP 71111.11. Documents reviewed listed in the
.
b. Findings
Introduction:
A Green NRC-identified NCV of 10 CFR 55.49, Integrity of examinations and tests, was identified for the licensees failure to conduct activities related to the preparation, administration, and grading of the tests and examinations required by this part. Operations Training Management Procedure 3.4 (OTMP 3.4 ASEDEV), Active Simulator Exam Development Guide, Revision 08, allowed no more than 50 percent scenario overlap between examinations.
Description:
The licensee administered two simulator exam scenarios to each licensed operator as part of their annual operating examination. Procedure OTMP 3.4, Section 6.14, Simulator Exam (ASE) Selection, required one new ASE and one ASE from the previous week to ensure no more than 50% overlap occurs. While reviewing the 2012 licensed operator requalification exam schedule, the inspectors identified that two exam scenarios, scheduled to be administered during the fourth week of the 2012 requalification schedule, had already been administered during previous weeks of the 2012 requalification schedule. The inspectors notified the licensee of the scenario examination schedule overlap and the licensee revised the examination schedule. The inspectors also reviewed the 2011 annual operating exam administration schedule and identified two simulator exam scenarios administered during week five of the 2011 annual operating exams had been administered during previous weeks of the 2011 operating exam.
Analysis:
The inspectors determined that the licensees failure to adhere to OTMP 3.4 was a PD. The PD was determined to be more than minor because it was associated with the Human Performance attribute of the Mitigating Systems Cornerstone, and adversely affected the cornerstone objective in that the failure to adhere to examination overlap standards adversely affected the quality of the operating exams which test licensed operator performance. The significance determination was performed in accordance with Manual Chapter 0609, Significance Determination Process, Appendix I, Licensed Operator Requalification Significance Determination Process (SDP). Question 10 was answered as YES because the finding was related to excessive test item repetition between requalification examinations administered during different weeks of a training cycle. Question 11 was NO because there was no evidence that a licensed operator had actually gained an unfair advantage on an examination required by 10 CFR 55.59, Requalification. Therefore, this finding was characterized as having very low safety significance (Green). The finding was directly related to the cross-cutting aspect of complete, accurate, and up-to-date procedures for the resources component of the cross-cutting area of Human Performance because the methodology in OTMP 3.4 not ensure that no more than 50 percent of scenario events were repeated and the scenario sequencing method was predictable. H.2(c)
Enforcement:
10 CFR 55.49 stated that applicants, licensees, and facility licensees shall not engage in any activity that compromises the integrity of any application, test, or examination required by this part. The integrity of a test or examination was considered compromised if any activity, regardless of intent, affected, or would have affected the equitable and consistent administration of the test or examination. This includes activities related to the preparation and certification of license applications and all activities related to the preparation, administration, and grading of the tests and examinations required by this part. Activities covered by this part include the requirements stated in 10 CFR 55.59, Requalification. The annual operating exam administered to all licensed operators was required by 10 CFR 55.59. Contrary to the above, during the 2011 and 2012 licensed operator requalification cycles, licensee personnel engaged in an activity that compromised the integrity of the annual operating examination, in that personnel failed to adhere to examination procedure standards for scenario overlap, and but for detection, this activity would have affected the equitable and consistent administration of the 2012 operating examination. Because this issue is of very low safety significance and has been entered into the licensees corrective action program, PIPs C-12-06949 and C-12-06950, the violation is being treated as a NCV consistent with the NRC Enforcement Policy: NCV 50-413, 414/2012004-02, Failure to Maintain Requalification Examination Integrity.

Force Recommendation 2.3 Flooding Walkdowns, and NRC TI 2515/188, Inspection of Near-Term Task Force Recommendation 2.3 Seismic Walkdowns
a. Inspection Scope
Inspectors accompanied the licensee on a sampling basis, during their flooding and seismic walkdowns, to verify that the licensees walkdown activities were conducted using the methodology endorsed by the NRC. These walkdowns are being performed at all sites 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.
3 of the March 12, 2012, letter requested licensees to perform seismic walkdowns using an NRC-endorsed walkdown methodology. Electric Power Research Institute (EPRI) document 1025286 titled, Seismic Walkdown Guidance, (ADAMS Accession No. ML12188A031) provided the NRC-endorsed methodology for performing seismic walkdowns to verify that plant features, credited in the current licensing basis (CLB) for seismic events, are available, functional, and properly maintained.
4 of the letter requested licensees to perform external flooding walkdowns using an NRC-endorsed walkdown methodology (ADAMS Accession No.
ML12056A050). Nuclear Energy Industry (NEI) document 12-07 titled, Guidelines for Performing Verification Walkdowns of Plant Protection Features, (ADAMS Accession No. ML12173A215) provided the NRC-endorsed methodology for assessing external flood protection and mitigation capabilities to verify that plant features, credited in the CLB for protection and mitigation from external flood events, are available, functional, and properly maintained.
b. Findings
Findings or violations associated with the flooding and seismic walkdowns, if any, will be documented in future reports.
4OA6 Meetings, Including Exit
Exit Meeting Summary
On October 11, 2012, the resident inspectors presented the inspection results to Mr.
Kelvin Henderson and other members of licensee management. The inspectors verified that no proprietary information was retained by the inspectors or documented in this report.
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 55.3 stated, in part, that a person must be authorized by a license issued by the Commission to perform the function of an operator or a senior operator. 10 CFR 50.54(l) stated, in part, that the [facility] licensee shall designate individuals to be responsible for directing the licensed activities of licensed operators, and that these individuals shall be licensed as senior operators pursuant to part 55 of this chapter.
Contrary to the above, on June 15, 2012, and June 18, 2012, the facility licensee allowed a person to perform the function of a senior operator who was not licensed by the Commission to perform those functions. The individuals senior operator license had been terminated by the Commissions regional office on June 12, 2012, at the licensees request. The inspectors determined that the violation was not greater than very low safety significance (Green) due to the short time the individual performed the senior licensed operator function, and because the individual was in all other aspects fully qualified and proficient as a senior licensed operator. This issue was entered in the licensees corrective action program as PIP-C-12-5489.
