SUBJECT:
H.B. ROBINSON STEAM ELECTRIC PLANT - NRC PROBLEM IDENTIFICATION AND RESOLUTION INSPECTION REPORT 05000261/2014008
Dear Mr. Gideon:
On May 8, 2014, the U.S. Nuclear Regulatory Commission (NRC) completed a problem identification and resolution biennial inspection at your H.B. Robinson Steam Electric Plant, Unit 2 and discussed the results of this inspection with Mr. R. Glover and other members of your staff. The inspection team documented the results of this inspection in the enclosed inspection report.
Based on the inspection samples, the inspection team determined that your staffs implementation of the corrective action program supported nuclear safety. In reviewing your corrective action program, the team assessed how well your staff identified problems at a low threshold, your staffs implementation of the stations process for prioritizing and evaluating these problems, and the effectiveness of corrective actions taken by the station to resolve these problems. In each of these areas, the team determined that your staffs performance was adequate to support nuclear safety.
The team also evaluated other processes your staff used to identify issues for resolution. These included your use of audits and self-assessments to identify latent problems and your incorporation of lessons learned from industry operating experience into station programs, processes, and procedures. The team determined that your stations performance in each of these areas supported nuclear safety.
Finally, the team determined that your stations management maintains a safety-conscious work environment adequate to support nuclear safety. Based on the teams observations, your employees are willing to raise concerns related to nuclear safety through at least one of the several means available.
However, the enclosed inspection report discusses one NRC-identified finding of very low safety significance (Green) identified during this inspection. This finding was determined to involve a violation of NRC requirements. The NRC is treating this violation as a non-cited violation (NCV)
consistent with Section 2.3.2.a of the Enforcement Policy. If you contest the violation or the significance of this NCV, you should provide a response within 30 days of the date of this inspection report, with the basis for your denial, to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington DC 20555-0001; with copies to the Regional Administrator, Region II; the Director, Office of Enforcement, U.S.
Nuclear Regulatory Commission, Washington, DC 20555-0001; and the NRC resident inspector at the H.B. Robinson facility.
In accordance with Title 10 of the Code of Federal Regulations 2.390, Public Inspections, Exemptions, Requests for Withholding, of the NRC's Rules of Practice, a copy of this letter, its enclosure, and your response (if any) will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS) component of the NRC's Agencywide Documents Access and Management System (ADAMS). ADAMS is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).

SUMMARY OF FINDINGS
IR 05000261/2014008; April 21 - May 8, 2014; H.B. Robinson Steam Electric Plant, Unit 2;
Biennial Inspection of the Problem Identification and Resolution Program.
The inspection was conducted by three senior project engineers, one senior project inspector, a project engineer, and a reactor inspector. One finding of very low safety significance (Green)was identified during this inspection. The significance of inspection findings are indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using IMC 0609, Significance Determination Process, dated June 2, 2011. Cross-cutting aspects are determined using IMC 0310, Aspects Within Cross Cutting Areas, dated December 19, 2013.
All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 5.
Identification and Resolution of Problems
The inspectors concluded that, in general, problems were properly identified, evaluated, prioritized, and corrected. The licensee was effective at identifying problems and entering them into the corrective action program (CAP) for resolution, as evidenced by the relatively few number of deficiencies identified by external organizations (including the NRC) that had not been previously identified by the licensee, during the review period. Generally, prioritization and evaluation of issues were adequate, formal root cause evaluations for significant problems were adequate, and corrective actions specified for problems were acceptable. Overall, corrective actions developed and implemented for issues were generally effective and implemented in a timely manner. However, the team did identify deficiencies in the areas of identification of problems and effectiveness of corrective actions.
The inspectors determined that overall audits and self-assessments were adequate in identifying deficiencies and areas for improvement in the CAP, and appropriate corrective actions were developed to address the issues identified. Operating experience usage was found to be generally acceptable and integrated into the licensees processes for performing and managing work, and plant operations.
Based on discussions and interviews conducted with plant employees from various departments, the inspectors determined that personnel at the site felt free to raise safety concerns to management and use the CAP to resolve those concerns.
NRC-Identified and Self-Revealing Findings
Cornerstone: Initiating Events
Green: The team identified a Green NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, for the licensees failure to take adequate corrective action to prevent repetition of a significant condition adverse to quality regarding steam generator tube leakage due to poor maintenance practices. Specifically, on February 27, 2014, the C steam generator showed indications of a primary to secondary tube leak due to foreign material that was introduced during the fall 2013 refueling outage. As immediate corrective actions, on March 7, 2014, the licensee shutdown the plant and repaired the leak. This violation was entered into the licensees CAP as nuclear condition reports (NCRs) 683695, 683593, and 683591.
The licensees failure to implement appropriate corrective actions to address poor worker practices to prevent recurrence of a steam generator tube leak was a performance deficiency.
The finding was more than minor because it was associated with the initiating events cornerstone equipment performance attribute and it adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, foreign material entered the steam generator and damaged a steam generator tube, which increased the likelihood of a steam generator tube rupture. The inspectors screened this finding using IMC 0609, Appendix A, The Significant Determination Process (SDP) For Findings At-Power, dated June 19, 2012.
The finding screened as Green per Section D of Exhibit 1, Initiating Events Screening Questions, because testing showed that the affected steam generator tube could sustain three times the differential pressure across the tube during normal full power and that the steam generator did not violate the accident leakage performance criterion. The performance deficiency does not have a cross cutting aspect because the last revision of the root cause evaluation was completed in 2011 and it is not indicative of current licensee performance.

REPORT DETAILS
OTHER ACTIVITIES
4OA2 Problem Identification and Resolution
.1 Corrective Action Program Effectiveness
a. Inspection Scope
The inspectors reviewed the licensees CAP procedures which described the administrative process for initiating and resolving problems primarily use of NCRs. To verify that problems were being properly identified, appropriately characterized, and entered into the CAP, the inspectors reviewed NCRs that had been issued between June 2012 and April 2014, including a detailed review of selected NCRs associated with the following risk-significant systems: auxiliary feedwater, reactor protection system, and alternating current (AC) distribution system. Where possible, the inspectors independently verified that the corrective actions were implemented as intended. The inspectors also reviewed selected common causes and generic concerns associated with root cause evaluations to determine if they had been appropriately addressed. To help ensure that samples were reviewed across all cornerstones of safety identified in the NRCs Reactor Oversight Process (ROP), the inspectors selected a representative number of NCRs that were identified and assigned to the major plant departments, including emergency preparedness, health physics, chemistry, and security. These NCRs were reviewed to assess each departments threshold for identifying and documenting plant problems, thoroughness of evaluations, and adequacy of corrective actions. The inspectors reviewed selected NCRs, verified corrective actions were implemented, and attended meetings where NCRs were screened for significance to determine whether the licensee was identifying, accurately characterizing, and entering problems into the CAP at an appropriate threshold.
The inspectors conducted plant walk-downs of equipment associated with the selected systems and other plant areas to assess the material condition and to look for any deficiencies that had not been previously entered into the CAP. The inspectors reviewed NCRs, maintenance history, completed work orders (WOs) for the systems, and reviewed associated system health reports. These reviews were performed to verify that problems were being properly identified, appropriately characterized, and entered into the CAP. Items reviewed generally covered a two-year period of time; however, in accordance with the inspection procedure, a five-year review was performed for selected systems for age-dependent issues.
Control room walk-downs were also performed to assess the main control room deficiency list and to ascertain if deficiencies were entered into the CAP. Operator workarounds and operator burden screenings were reviewed, and the inspectors verified compensatory measures for deficient equipment which were being implemented in the field.
The inspectors conducted a detailed review of selected NCRs to assess the adequacy of the root-cause and apparent-cause evaluations of the problems identified. The inspectors reviewed these evaluations against the issues discussed in the NCRs and the guidance in licensee procedure CAP-NGGC-0205, Condition Evaluation and Corrective Action Process. The inspectors assessed if the licensee had adequately determined the cause(s) of identified problems, and had adequately addressed operability, reportability, common cause, generic concerns, extent of condition, and extent of cause.
The review also assessed if the licensee had appropriately identified and prioritized corrective actions to prevent recurrence.
The inspectors reviewed selected industry operating experience items, including NRC generic communications to verify that they had been appropriately evaluated for applicability and that issues identified through these reviews had been entered into the CAP.
The inspectors reviewed site trend reports to determine if the licensee effectively trended identified issues and initiated appropriate corrective actions when adverse trends were identified.
The inspectors reviewed licensee audits and self-assessments, including those which focused on problem identification and resolution programs and processes, to verify that findings were entered into the CAP and to verify that these audits and assessments were consistent with the NRCs assessment of the licensees CAP. The inspectors attended various plant meetings to observe management oversight functions of the corrective action process. These included Work Ownership Committee (WOC) meetings and Performance Improvement Oversight Committee (PIOC) meetings.
Documents reviewed are listed in the Attachment.
b.
Assessment
Problem Identification
The inspectors determined that the licensee was generally effective in identifying problems and entering them into the CAP and there was a low threshold for entering issues into the CAP. This conclusion was based on a review of the requirements for initiating NCRs as described in licensee procedures CAP-NGGC-0200, Condition Identification and Screening Process, managements expectation that employees were encouraged to initiate NCRs for any reason, and the relatively few number of deficiencies identified by inspectors during plant walkdowns not already entered into the CAP. Site management was actively involved in the CAP and focused appropriate attention on significant plant issues.
Based on reviews and walkdowns of accessible portions of the selected systems, the inspectors determined that system deficiencies were being identified and placed in the CAP.
The team identified a performance deficiency associated with the licensees problem identification of issues. This issue was screened as minor in accordance with IMC 0612 Appendix B, Issue Screening.
- During the review of NCR 605058, the inspectors identified a performance deficiency for failure to identify a condition adverse to quality associated with deficiencies of post maintenance testing (PMT) of reactor protection and safeguards relays. The failure to properly identify that procedure PLP-033, Post Maintenance Testing Program, did not provide measures to ensure that full functional test were developed for reactor protection and safeguards relays was a performance deficiency. This performance deficiency was considered minor because the safety related functions of the identified safety related relays affected were being verified via operation surveillance test (OST) procedures. This issue has been documented as NCRs 0685848, 0683751, 0686111 and 0685871.
Problem Prioritization and Evaluation
Based on the review of NCRs sampled by the inspection team during the onsite period, the inspectors concluded that problems were generally prioritized and evaluated in accordance with the NCR significance determination guidance in CAP-NGGC-0200.
The inspectors determined that adequate consideration was given to system or component operability and associated plant risk.
The inspectors determined that station personnel had conducted root cause and apparent cause analyses in compliance with the licensees CAP procedures and assigned cause determinations were appropriate, considering the significance of the issues being evaluated. A variety of formal causal-analysis techniques were used to evaluate NCRs depending on the type and complexity of the issue consistent with CAP-NGGC-0205.
Effectiveness of Corrective Actions
Based on a review of corrective action documents, interviews with licensee staff, and verification of completed corrective actions, the inspectors determined that overall, corrective actions were timely, commensurate with the safety significance of the issues, and effective, in that conditions adverse to quality were corrected and non-recurring. For significant conditions adverse to quality, the corrective actions directly addressed the cause and effectively prevented recurrence in that a review of performance indicators, NCRs, and effectiveness reviews demonstrated that the significant conditions adverse to quality had not recurred. Effectiveness reviews for corrective actions to prevent recurrence (CAPRs) were sufficient to ensure corrective actions were properly implemented and were effective.
However, the team identified one example where the licensee failed to take adequate corrective actions to preclude repetition. This issue is described below in the Findings section, Section 4OA2.1.c of this report as Failure to Take Adequate Corrective Action to Preclude Repetition of a Significant Condition Adverse to Quality Associated with the Steam Generator Tube Leak.
In addition, the team identified a performance deficiency associated with the licensees effectiveness of corrective actions. This issue was screened as minor in accordance with IMC 0612 Appendix B, Issue Screening.
- Procedure CAP-NGGC-0205, Condition Evaluation and Corrective Action Process, Section 9.2 Corrective Action Plan, states that: A corrective action (CORR) shall not be closed to a lower tier assignment type. The inspectors identified three examples of inadequate closure of CORRs to lower tier assignments. Specifically, NCRs 645821-12 and 635420-5 were closed to procedure revision requests (PRRs)and NCR 640903-3 was closed to a training request form (TRF). The closing of the CORRs to lower tier assignments was a performance deficiency. This performance deficiency was minor because even though the PRRs are still open they are scheduled to be completed prior to the affected procedures being used. Also, the TRF was completed and determined that no training was required. This issue has been documented as NRC 686121.
c. Findings
Introduction:
The team identified a Green NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Actions, for the licensees failure to take adequate corrective action to prevent repetition of a significant condition adverse to quality regarding steam generator tube leakage due to poor maintenance practices.
Description:
On January 8, 2004, the licensee documented a significant condition adverse to quality regarding evidence of a minor primary to secondary side leakage.
The licensee initiated NCR 115704 and performed a root cause evaluation (RCE). In Revision 1 of the RCE, the licensee determined that one of the root causes of the steam generator tube leak was poor maintenance work practices. To address this root cause, the licensee implemented the following CAPR:
- CAPR 115704-17: Revise as necessary ADM-NGGC-0110, Oversight of Contractors, Shared Resources, Vendors, and Technical Representatives, to include this action request subject matter, for review, in the maintenance services orientation package for secondary maintenance every outage.
On June 9, 2010, during an effectiveness review per NCR 115704-20; the licensee determined that poor worker practices were not effectively addressed by the CAPRs.
The licensee performed an adverse condition investigation to evaluate the ineffective corrective actions (NCR 403879). As a result of the investigation, the licensee determined that the following CAPR was going to be added to the original RCE (NCR 115704 Rev.3, completed on August 9, 2011) to address poor maintenance work practices:
- CAPR 115704-23: Provide training to address poor foreign material exclusion (FME)performance in accordance with the INPO letter on Causal Analysis for Foreign Material Intrusion Events.
Root Cause 115704 Revision 3 also added the following CAPR and CORRs to address poor work practices:
- Revise procedure MNT-NGGC-007, Foreign Material Exclusion Program, to address foreign material created by the degradation of plant equipment differently from FME issues caused during the maintenance activity in process.
- CORR 115704-30: Revise existing FME training to include a dynamic learning activity (DLA) that incorporates FME recognition, reinforces notification for loss of FME controls and include risk awareness.
- CORR 115704-31: Formalized oversight of contractor FME performance during work on open secondary systems. Oversight must be documented and include unannounced field inspections of logs and plant systems while work is in progress.
The inspectors identified the following issues with the licensees corrective actions listed above:
- CAPR 115704-17 was not adequately implemented. The maintenance orientation package was revised, however procedure ADM-NGGC-0110 was not revised; therefore the action completed was not pragmatic and was not carried into the last refueling outage in fall 2013.
- CAPR 115704-23 was canceled and no other CAPR was initiated to address the root cause associated with poor maintenance practices.
- The licensee intended to implement a CAPR to revise procedure MNT-NGGC-007; however, this CAPR was never properly implemented in the CAP. The changes in the procedure were implemented as part of several PRRs, outside of RCE 115704, Revision 3. The changes did not address the poor worker practices root cause.
- CORR 115704-30 was not implemented as written. A DLA was developed for monitoring of foreign materials that are not immediately retrievable (FME-1).
However, the DLA didnt included FME recognition, notification for loss of FME controls and risk awareness.
- CORR 115704-31 was not implemented as written. There was no documentation that this action was carried forward pragmatically into future refueling outages. Also, there was no documentation in the closure of oversight of non-outage activities.
Based on the issues identified above, the inspectors determined that the licensee did not have adequate CAPRs in place to address the poor worker practices root cause identified in RCE 115704.
On February 27, 2014, the C steam generator showed indications of a primary to secondary tube leak. On March 7, 2014, the licensee shutdown the plant and repaired the leak. The licensee identified that the leak was caused by a loose part. The licensee conducted a cause evaluation and determined that the foreign material was introduced during replacement of a feedwater piping upstream of the C steam generator during the fall 2013 refueling outage.
Analysis:
The licensees failure to implement appropriate corrective actions to address poor worker practices to prevent recurrence of a steam generator tube leak was a performance deficiency. The finding was more than minor because it was associated with the initiating events cornerstone equipment performance attribute and it adversely affected the cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions during shutdown as well as power operations. Specifically, foreign material entered the steam generator and damaged a steam generator tube, which increased the likelihood of a steam generator tube rupture.
The inspectors screened this finding using IMC 0609, Appendix A, The Significant Determination Process For Findings At-Power, dated June 19, 2012. The finding screened as Green per Section D of Exhibit 1, Initiating Events Screening Questions, because testing showed that the affected steam generator tube could sustain three times the differential pressure across the tube during normal full power and that the steam generator did not violate the accident leakage performance criterion. The performance deficiency does not have a cross cutting aspect because the last revision of the root cause evaluation was completed in 2011 and it is not indicative of current licensee performance.
Enforcement:
10 CFR 50 Appendix B Criterion XVI, Corrective Actions, states in part, for significant conditions adverse to quality, the measures shall assure that the cause of the condition is determined and corrective action taken to preclude repetition. Contrary to the above, the licensee did not take appropriate corrective actions to preclude repetition for a significant condition adverse to quality that was identified in January 18, 2004, regarding steam generator tube leak due to poor worker practices. Specifically, on February 27, 2014, the C steam generator had a primary to secondary tube leak which the licensee determined to be due to foreign material that was introduced by poor worker practices (FME controls) during replacement of feedwater piping upstream of the C steam generator during the fall 2013 refueling outage. As immediate corrective actions, on March 7, 2014, the licensee shutdown the plant and repaired the leak. This violation is being treated as an NCV, consistent with Section 2.3.2 of the Enforcement Policy. The violation was entered into the licensees corrective action program as NCRs 683695, 683593, and 683591. NCV 05000261/2014008-01, Failure to Take Adequate Corrective Action to Preclude Repetition of a Significant Condition Adverse to Quality Associated with the Steam Generator Tube Leak.
.2 Use of Operating Experience
a. Inspection Scope
The inspectors examined licensee programs for reviewing industry operating experience (OE), reviewed licensee procedure CAP-NGGC-0202, Operating Experience and Construction Experience Program, reviewed the licensees operating experience database to assess the effectiveness of how external and internal operating experience data was handled at the plant. In addition, the inspectors selected operating experience documents (e.g., NRC generic communications, 10 CFR Part 21 reports, licensee event reports, vendor notifications, and plant internal operating experience items, etc.), which had been issued since June 2012 to verify whether the licensee had appropriately evaluated each notification for applicability to the Robinson Nuclear plant, and whether issues identified through these reviews were entered into the CAP.
Documents reviewed are listed in the Attachment.
b.
Assessment
Based on a review of documentation related to the review of operating experience issues, the inspectors determined that the licensee was generally effective in screening OE for applicability to the plant. Industry OE was evaluated by plant OE Coordinators and relevant information was then forwarded to the applicable department for further action or informational purposes. Operating experience issues requiring action were entered into the CAP for tracking and closure. In addition, OE was included in root cause evaluations in accordance with licensee procedure CAP-NGGC-0205.
c. Findings
No findings were identified.
.3 Self-Assessments and Audits
a. Inspection Scope
The inspectors reviewed audit reports and self-assessment reports, including those which focused on problem identification and resolution, to assess the thoroughness and self-criticism of the licensee's audits and self-assessments, and to verify that problems identified through those activities were appropriately prioritized and entered into the CAP for resolution in accordance with licensee procedures AD-PI-ALL-0300, Self-Assessment and Benchmark Programs.
Documents reviewed are listed in the Attachment.
b.
Assessment
The inspectors determined that the scopes of assessments and audits were adequate.
Self-assessments were generally detailed and critical, as evidenced by findings consistent with the inspectors independent review. The inspectors verified that NCRs were created to document all areas for improvement and findings resulting from the self-assessments and verified that actions were completed consistently with those recommendations. Generally, the licensee performed evaluations that were technically accurate. Site trend reports were thorough and a low threshold was established for evaluation of potential trends, as evidenced by the NCRs reviewed that were initiated as a result of adverse trends.
c. Findings
No findings were identified.
.4 Safety-Conscious Work Environment
a. Inspection Scope
The inspectors interviewed several on-site workers regarding their knowledge of the CAP at the Robinson Steam Electric Plant and their willingness to write NCRs or raise safety concerns. During technical discussions with members of the plant staff, the inspectors conducted interviews to develop a general perspective of the safety-conscious work environment at the site. The interviews were also conducted to determine if any conditions existed that would cause employees to be reluctant to raise safety concerns. The inspectors reviewed the licensees Employee Concerns Program (ECP) and interviewed the ECP coordinator. Additionally, the inspectors reviewed a sample of ECP issues to verify that concerns were properly reviewed and that identified deficiencies were resolved and entered into the CAP when appropriate.
Documents reviewed are listed in the Attachment.
b.
Assessment
Based on the interviews conducted and the NCRs reviewed, the inspectors determined that licensee management emphasized the need for all employees to identify and report problems using the appropriate methods established within the administrative programs, including the CAP and ECP. These methods were readily accessible to all employees.
Based on discussions conducted with a sample of plant employees from various departments, the inspectors determined that employees felt free to raise issues, and that management encouraged employees to place issues into the CAP for resolution. The inspectors did not identify any reluctance on the part of the licensee staff to report safety concerns.
c. Findings
No findings were identified.
4OA6 Meetings, Including Exit
On May 8, 2014, the inspectors presented the inspection results to Mr. R. Glover and other members of the site staff. The inspectors confirmed that all proprietary information examined during the inspection had been returned to the licensee.
