SUMMARY
IR 05000280/2015001, 05000281/2015001; 01/01/2015-03/31/2015; Surry Power Station,
Units 1 and 2: Maintenance Effectiveness The report covered a three-month period of inspection by resident inspectors and region-based inspectors. Inspectors identified one non-cited violation (NCV) of very low safety significance.
The significance of most findings is indicated by their color (Green, White, Yellow, Red) using Inspection Manual Chapter (IMC) 0609, Significance Determination Process (SDP), dated June 2, 2011. The cross-cutting aspect was determined using IMC 0310, Components Within The Cross-Cutting Areas, dated December 04, 2014. All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy, dated February 5, 2015. The NRCs program for overseeing the safe operation of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 5.
Cornerstone: Mitigating Systems
- Green.
An NRC-identified, non-cited violation (NCV) of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, was identified because the licensee failed to promptly identify a condition adverse to quality associated with the material condition of the Unit 2 charging service water (CH/SW) piping. Specifically, the NRC resident inspectors identified a leak in the discharge piping of the Unit 2 A CH/SW pump on November 24, 2014. The licensee had previously identified a leak on the Unit 1 B CH/SW pump discharge piping on June 16, 2014. The issue was documented in the licensees corrective action program (CAP) as condition report (CR) 563166.
The licensees failure to identify a condition adverse to quality associated with the material condition of the Unit 2 A CH/SW piping was a performance deficiency (PD). The inspectors determined that the PD was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, not having compensatory actions in place for CH/SW Green Thread piping that has been prone to through-wall leaks, left the licensee susceptible to undetected leaks from the CH/SW piping systems. Using Manual Chapter 0609.04, Initial Characterization of Findings, Table 2, dated June 19, 2012, the finding was determined to adversely affect the Mitigating Systems Cornerstone. The inspectors screened the finding using Manual Chapter 0609, Appendix A, Significance Determination Process (SDP) for Findings at-Power, dated June 19, 2012, and determined that it screened as Green because the PD did not affect the design or qualification of the CH/SW system and the leak rate did not represent an actual loss of system safety function. This finding has a cross-cutting aspect in the evaluation component of the problem identification and resolution, P.2, because the organization did not thoroughly evaluate issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance. Specifically, the license did not institute compensatory actions for a long-term corrective action on CH/SW piping that has had a recent history of developing through-wall leaks. (Section 1R12)

.3 Biennial Review of Licensed Operator Requalification Program
a. Inspection Scope
The inspectors reviewed the facility operating history and associated documents in preparation for this inspection. During the week of January 19, 2015, the inspectors reviewed documentation and observed the administration of operating tests associated with the licensees operator requalification program. Each of the activities performed by the inspectors was done 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 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-3-5-2009, American National Standard for Nuclear Power Plant Simulators for use in Operator Training and Examination. The inspectors observed two 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 Inspection Procedure 71111.11. Documents reviewed during the inspection are documented in the Attachment.
b. Findings
No findings were identified.
1R12 Maintenance Effectiveness
a. Inspection Scope
For the two equipment issues described in the condition reports listed below, the inspectors evaluated the effectiveness of the corresponding licensee's preventive and corrective maintenance. The inspectors performed a detailed review of the problem history and associated circumstances, evaluated the extent of condition reviews, as required, and reviewed the generic implications of the equipment and/or work practice problem(s). Inspectors performed walkdowns of the accessible portions of the system, performed in-office reviews of procedures and evaluations, and held discussions with system engineers. The inspectors compared the licensees actions with the requirements of the Maintenance Rule (10 CFR 50.65), station procedures ER-AA-MRL-10, Maintenance Rule Program, Revision 6, and ER-AA-MRL-100, Implementing the Maintenance Rule, Revision 6.
- CR 566136, CH/SW piping leaks
- CR 570282, Unit 2 B Main Feed Pump seal replacement
b. Findings
Introduction:
An NRC-identified Green NCV of 10 CFR 50, Appendix B, Criterion XVI, Correction Action, was identified because the licensee failed to promptly identify a condition adverse to quality associated with the material condition of the Unit 2 CH/SW piping. Specifically, the NRC resident inspectors identified a leak in the discharge piping of the Unit 2 A CH/SW pump on November 24, 2014. The licensee had previously identified a leak on the Unit 1 B CH/SW pump discharge piping on June 16, 2014.
Description:
On June 16, 2014 the licensee identified a leaking joint on the discharge of 1-SW-P-10B, the B CH/SW pump, located in mechanical equipment room (MER) 3.
The leak was identified as a through-wall leak and the B CH/SW pump was declared inoperable. The licensee entered a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> limiting condition for operation (LCO) for one train of high head safety injection not available. The licensee replaced the section of piping on June 17, and the B CH/SW pump was declared operable. This issue was documented in the licensees CAP as CR 551846.
The section of CH/SW piping that developed the leak was made of Green Thread material. Green Thread is a trade-marked name for piping that is filament wound using amine-cured epoxy resins and fiberglass. The leak developed in the section of piping that is connected by glue to the flanged end of the piping. The licensees CH/SW piping mainly consists of fiberglass reinforced thermosetting resin pipe (RTRP) that meets the requirements of American Society of Mechanical Engineers (ASME) code case N-155-2 and Green Thread piping.
The licensee has had previous cracks or leaks of the Green Thread sections of CH/SW piping. The two most recent were in 2004 on the discharge of the Unit 2 A CH/SW pump and in December, 2012 on the discharge of the Unit 2 A CH/SW pump. The root cause evaluation (RCE) conducted on the 2004 issue attributed the cause to an improperly made joint which caused a tension overload on the Green Thread pipe.
The apparent cause evaluation (ACE) conducted on the 2012 issue attributed the cause to incomplete application of glue to the fiberglass joint.
The licensee conducted an ACE that included failure analysis of the leaking section of pipe. The ACE determined the apparent cause to be a bending or stretching event that overloaded the pipe. The overload event could not exactly be determined and was attributed to a combination of torque application to the flanged connection, operational transient in the CH/SW system, and inadvertent contact of the piping which is located at foot level. The corrective action for the apparent cause was for the licensee engineering department to present to the plant health working group a case for replacing the piping downstream of the CH/SW pumps with copper-nickel piping. No compensatory actions were put into place for the permanent corrective action of evaluating replacing the piping with copper-nickel, despite the history of leaks on the Green Thread piping.
Based on the number of issues with leaks on CH/SW piping and the range of apparent cause failure methods of the June, 2014 leak, the resident inspectors began to conduct more frequent walkdowns of this piping. On November 24, 2014, the inspectors found water dripping from underneath the insulation of the discharge piping from the Unit 2 A CH/SW pump. The licensee removed the insulation and found a pipe leak of approximately 45 drops per minute from a section of Green Thread piping. The pump was declared inoperable and the licensee entered a 72hour LCO for one train of high head safety injection not available. The licensee replaced the section of piping that same day and the Unit 2 A CH/SW pump was declared operable. This issue was documented in the licensees CAP as CR 563166.
The licensee conducted an ACE on the Unit 2 A CH/SW discharge pipe leak and concluded that the apparent cause of the leak was stresses placed on the piping from the original torqueing of the bolting, minor pipe misalignment, minor vibrations from the CH/SW pump, and possible personnel contact. After the leak was found by the resident inspectors, the licensee instituted a monthly engineering walkdown of all CH/SW piping in MER-3 and 4 as a compensatory action.
Analysis:
The inspectors determined that failure to identify a condition adverse to quality associated with the material condition of the Unit 2 A CH/SW piping was a PD that was within the licensees ability to foresee and correct. The inspectors determined that the PD was more than minor because it was associated with the equipment performance attribute of the Mitigating Systems Cornerstone and adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, not having compensatory actions in place for CH/SW Green Thread piping that has been prone to through-wall leaks, left the licensee susceptible to undetected leaks from the CH/SW piping systems. Using Manual Chapter 0609.04, Initial Characterization of Findings, Table 2, dated June 19, 2012; the finding was determined to adversely affect the Mitigating Systems Cornerstone. The inspectors screened the finding using Manual Chapter 0609, Appendix A, Significance Determination Process (SDP) for Findings at-Power, dated June 19, 2012, and determined that it screened as Green because the PD did not affect the design or qualification of the CH/SW system and the leak rate did not represent an actual loss of system safety function. This finding has a cross-cutting aspect in the evaluation component of the problem identification and resolution, P.2, because the organization did not thoroughly evaluate issues to ensure that resolutions address causes and extent of conditions commensurate with their safety significance.
Specifically, the license did not institute compensatory actions for a long-term corrective action on CH/SW piping that has had a recent history of developing through-wall leaks.
Enforcement:
10 CFR 50, Appendix B, Criterion XVI, Corrective Action, states, in part, Measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified. Contrary to the above, on November 24, 2014, the licensee did not promptly identify a leak in the discharge piping of the Unit 2 A CH/SW pump. Specifically, the licensee had no compensatory actions in place to detect leaks on CH/SW piping that had been known to develop leaks in the past, the reason for the leaks could not always be determined, and the permanent corrective action was to evaluate replacing the piping with copper-nickel piping.
Because the licensee entered the issue into their CAP as CR 563166 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 05000281/2015001-01, Failure to Identify Charging Service Water Pipe Leak.
1R13 Maintenance Risk Assessments and Emergent Work Control
a. Inspection Scope
The inspectors evaluated, as appropriate, the four activities listed below for the following:
- (1) the effectiveness of the risk assessments performed before maintenance activities were conducted;
- (2) the management of risk;
- (3) that, upon identification of an unforeseen situation, necessary steps were taken to plan and control the resulting emergent work activities; and
- (4) that maintenance risk assessments and emergent work problems were adequately identified and resolved. The inspectors verified that the licensee was complying with the requirements of 10 CFR 50.65(a)(4) and the data output from the licensees safety monitor associated with the risk profile of Units 1 and 2.
The inspectors reviewed the corrective action program to verify deficiencies in risk assessments were being identified and properly resolved.

4OA2 Identification and Resolution of Problems
.1 Daily Reviews of items Entered into the Corrective Action Program:
a. Inspection Scope
As required by NRC Inspection Procedure 71152, Identification and Resolution of Problems, and in order to help identify repetitive equipment failures or specific human performance issues for follow-up, the inspectors performed a daily screening of items entered into the licensees CAP. This review was accomplished by reviewing daily CR report summaries and periodically attending daily CR Review Team meetings.
b. Findings
No findings were identified.
.2 Semi-Annual Trend Review
a. Inspection Scope
The inspectors performed a review of the licensees CAP documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors review was focused on repetitive equipment and corrective maintenance issues, but also considered the results of daily inspector CAP item screening discussed in Section 4OA2.1. The review included issues documented outside the normal correction action program in system health reports, corrective maintenance work orders, component status reports, site monthly meeting reports, and maintenance rule assessments. The inspectors review nominally considered the six month period of July through December, 2014, although some examples expanded beyond those dates when the scope of the trend warranted.
The inspectors compared and contrasted their results with the results contained in the licensees latest integrated quarterly assessment report. Corrective actions associated with a sample of the issues identified in the licensees trend report were reviewed for adequacy.
b. Assessment and Observations No findings of significance were identified. In general, the licensee has identified trends and has addressed the trends with their CAP. No new adverse trends were identified this period that had not already been identified by the licensee.
4OA6 Meetings, Including Exit
Exit Meeting Summary
On April 15, 2015, the inspection results were presented to Mr. L. Lane and other members of his staff, who acknowledged the findings. The inspectors asked the licensee whether any of the material examined during the inspection should be considered proprietary. No proprietary information was identified.
