Criterion V, Procedures, Instructions, and Drawings, for the licensees failure to prove operability following a failure of a surveillance test as required by Hatch procedure 90AC-OAM-001-0, Test and Surveillance Control, Ver. 1.0, on May 12, 2014. To restore compliance, the licensee isolated the refueling floor dampers and re-performed Surveillance Requirement 3.6.4.1.3 with satisfactory results later that day on May 12, 2014. This violation was entered into the licensees corrective action program as condition report (CR)819563. | |||
819563. | |||
Exhibit 3, | Failure to prove operability following failure of a surveillance test as required by Hatch procedure 90AC-OAM-001-0, Test and Surveillance Control, Ver. 1.0, on May 12, 2014, was a performance deficiency. The performance deficiency affected the barrier integrity cornerstone and was more-than-minor because, if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, declaring equipment operable following a failed surveillance test would have the potential for the facility to operate outside of technical specification requirements. 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 C of Exhibit 3, Barrier Integrity Screening Questions, because the finding only represented a degradation of the radiological barrier function provided by the standby gas treatment system. The inspectors determined the finding had a cross-cutting aspect of training in the human performance area, because the licensee did not ensure knowledge transfer of Surveillance Requirement 3.0.1 requirements to maintain a knowledgeable, technically competent workface and instill nuclear safety values.

=====Description:===== | =====Description:===== | ||
On May 12, 2014, SNC performed Technical Specification 3.6.4.1 Surveillance Requirement 3.6.4.1.3 per SNC procedure 34SV-T22-001-0, | On May 12, 2014, SNC performed Technical Specification 3.6.4.1 Surveillance Requirement 3.6.4.1.3 per SNC procedure 34SV-T22-001-0, Secondary Containment Test, Ver. 15.1. This test verifies required standby gas treatment subsystems will draw down secondary containment to greater than or equal to 0.20 inch of vacuum water gauge in less than or equal to 120 seconds. The licensee was performing this test as a post maintenance test following maintenance on the Unit 2 refueling floor vent exhaust fans inboard isolation damper, 2T41-F003A. At 04:05 the control room logs documented that the secondary containment drawdown test did not meet acceptance criteria and Technical Specification Required Action Statement 3.6.4.1. | ||
Condition A was entered. The control room logs also documented that Required Action Statement 3.6.4.1 Condition A was exited at 05:57 because 2T41-F003A and 2T41-F023A, refueling floor vent exhaust fans discharge isolation dampers, had been deactivated/tagged out. SNC procedure NMP-AD-012, Operability Determination and Functionality Assessments, Ver. 12.3, is the procedure for determining and documenting the operability of systems, structures, or components when a degraded or non-conforming condition is found or suspected to exist. NMP-AD-012, Section 2.0.13, states, Technical specification operability considerations require that a system, structure, or component meet all surveillance requirements (as specified in Surveillance Requirement (SR) Applicability SR 3.0.1). A system, structure, or component that does not meet a surveillance requirement must be declared inoperable. Technical Specification Surveillance Requirement 3.0.1 states, Failure to meet a surveillance, whether such failure is experienced during the performance of the surveillance or between performance of the surveillances, shall be failure to meet the limiting condition for operability. With secondary containment failing to meet Surveillance Requirement 3.6.4.1.3 as documented in the most recent surveillance test, 34SV-T22-001-0, NMP-AD-012 required that secondary containment be declared inoperable. Hatch procedure 90AC-OAM-001-0, Test and Surveillance Control, Ver. 1.0, Section 5.2.10.4, contains actions following unsatisfactory surveillance testing results and states in part, To prove operability, a surveillance test shall be run on the equipment, system, or component as required by the surveillance requirement. Upon satisfactory completion of the surveillance test, operability will be declared. However, SNC senior reactor operators declared secondary containment operable without obtaining satisfactory surveillance test results for secondary containment following a failed secondary containment surveillance test. | |||
=====Analysis:===== | =====Analysis:===== | ||
Failure to prove operability following failure of a surveillance test as required by Hatch procedure 90AC-OAM-001-0, | Failure to prove operability following failure of a surveillance test as required by Hatch procedure 90AC-OAM-001-0, Test and Surveillance Control, Ver. 1.0, on May 12, 2014, was a performance deficiency. The performance deficiency affected the barrier integrity cornerstone and was more-than-minor because, if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, declaring equipment operable following a failed surveillance test would have the potential for the facility to operate outside of technical specification requirements. 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 C of Exhibit 3, Barrier Integrity Screening Questions, because the finding only represented a degradation of the radiological barrier function provided by the standby gas treatment system. The inspectors determined the finding had a cross-cutting aspect of training in the human performance area, because the licensee did not ensure knowledge transfer of Surveillance Requirement 3.0.1 requirements to maintain a knowledgeable, technically competent workface and instill nuclear safety values. [H.9] | ||
=====Enforcement:===== | |||
Enforcement | 10 CFR 50, Appendix B, Criterion V, Procedure, Drawings, and Instructions, requires in part that activities affecting quality shall be accomplished in accordance with documented instructions, procedures, or drawings, of a type appropriate to the circumstances. Hatch procedure NMP-AD-012, Operability Determination and Functionality Assessments, Ver. 12.3, Section 2.0.13 states in part, Technical specification operability considerations require that a system, structure, or component meet all surveillance requirements (as specified in Surveillance Requirement (SR) Applicability SR 3.0.1). A system, structure, or component that does not meet a surveillance requirement must be declared inoperable. In addition, Hatch procedure 90AC-OAM-001-0, Test and Surveillance Control, Ver. 1.0, Section 5.2.10.4, contains actions following unsatisfactory surveillance testing results and states in part, To prove operability, a surveillance test shall be run on the equipment, system, or component as required by the surveillance requirement. Upon satisfactory completion of the surveillance test, operability will be declared. Contrary to this requirement, on May 12, 2014, the licensee failed to accomplish an operability determination and failed to prove operability of secondary containment prior to declaring it operable. Specifically, senior reactor operators declared secondary containment operable after failing Surveillance Requirement 3.6.4.1.3 and did not prove operability by satisfactorily performing the surveillance test prior to declaring the secondary containment operable on May 12, 2014. To restore compliance, the licensee isolated the refueling floor dampers and re-performed Surveillance Requirement 3.6.4.1.3 with satisfactory results later that day on May 12, 2014. 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 CR 819563. (NCV 05000321, 366/2014003-01, Failure to Prove Operability Following the Failure of the Secondary Containment Surveillance Test) | ||

SUMMARY OF FINDINGS
IR 05000321/2014003; and 05000366/2014003, April 1, 2014, through June 30, 2014; Edwin I.
Hatch, Units 1 and 2, Operability Determinations and Functionality Assessments The report covered a 3-month period of inspection by resident inspectors and regional inspectors. There was one NRC identified violation identified and documented in this report.
The significance of inspection findings are indicated by their color (i.e., greater than Green, or Green, White, Yellow, Red) and determined using Inspection Manual Chapter (IMC) 0609,
Significance Determination Process (SDP) dated June 2, 2011. The cross-cutting aspects are determined using IMC 0310, Aspects within the Cross-Cutting Areas dated December 19, 2013. All violations of NRC requirements are dispositioned in accordance with the NRCs Enforcement Policy dated January 28, 2013. The NRCs program for overseeing the safe operations of commercial nuclear power reactors is described in NUREG-1649, Reactor Oversight Process, Revision 5.
Cornerstone: Barrier Integrity
- Green.
The inspectors identified a Green non-cited violation of 10 CFR 50, Appendix B,
Criterion V, Procedures, Instructions, and Drawings, for the licensees failure to prove operability following a failure of a surveillance test as required by Hatch procedure 90AC-OAM-001-0, Test and Surveillance Control, Ver. 1.0, on May 12, 2014. To restore compliance, the licensee isolated the refueling floor dampers and re-performed Surveillance Requirement 3.6.4.1.3 with satisfactory results later that day on May 12, 2014. This violation was entered into the licensees corrective action program as condition report (CR)819563.
Failure to prove operability following failure of a surveillance test as required by Hatch procedure 90AC-OAM-001-0, Test and Surveillance Control, Ver. 1.0, on May 12, 2014, was a performance deficiency. The performance deficiency affected the barrier integrity cornerstone and was more-than-minor because, if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, declaring equipment operable following a failed surveillance test would have the potential for the facility to operate outside of technical specification requirements. 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 C of Exhibit 3, Barrier Integrity Screening Questions, because the finding only represented a degradation of the radiological barrier function provided by the standby gas treatment system. The inspectors determined the finding had a cross-cutting aspect of training in the human performance area, because the licensee did not ensure knowledge transfer of Surveillance Requirement 3.0.1 requirements to maintain a knowledgeable, technically competent workface and instill nuclear safety values. [H.9] (Section 1R15)
REPORT DETAILS
Summary of Plant Status
Unit 1 began the inspection period at 100 percent rated thermal power (RTP). On May 31, 2014, operators reduced unit power to 25 percent RTP in response to a loss of feedwater heating transient. Operators returned the unit to 100 percent RTP on June 4, 2014. The unit remained at or near 100 percent RTP for the remainder of the inspection period.
Unit 2 operated at or near 100 percent RTP for the duration of the inspection period.

b. Findings
No findings were identified.
1R15 Operability Determinations and Functionality Assessments
a. Inspection Scope
The inspectors selected the five operability determinations or functionality evaluations listed below for review based on the risk-significance of the associated components and systems. The inspectors reviewed the technical adequacy of the determinations to ensure that technical specification operability was properly justified and the components or systems remained capable of performing their design functions. To verify whether components or systems were operable, the inspectors compared the operability and design criteria in the appropriate sections of the technical specification and updated final safety analysis report to the licensees evaluations. Where compensatory measures were required to maintain operability, the inspectors determined whether the measures in place would function as intended and were properly controlled. Additionally, the inspectors reviewed a sample of corrective action documents to verify the licensee was identifying and correcting any deficiencies associated with operability evaluations.
Documents reviewed are listed in the Attachment.
- Emergency diesel generator 2C air intake reinforcement screen missing, CR 798716
- Emergency diesel generator 2C fuel oil leak, CR 802941

- Secondary containment draw down surveillance test failure, CR 811574
- Unit 1 C residual heat removal pump failed to meet surveillance test acceptance criteria, CR 822066
b. Findings
Introduction:
The inspectors identified a Green non-cited violation of 10 CFR 50, Appendix B, Criterion V, Procedures, Instructions, and Drawings, when the licensee failed to prove operability following a failure of a surveillance test as required by Hatch procedure 90AC-OAM-001-0, Test and Surveillance Control, Ver. 1.0, on May 12, 2014.
Description:
On May 12, 2014, SNC performed Technical Specification 3.6.4.1 Surveillance Requirement 3.6.4.1.3 per SNC procedure 34SV-T22-001-0, Secondary Containment Test, Ver. 15.1. This test verifies required standby gas treatment subsystems will draw down secondary containment to greater than or equal to 0.20 inch of vacuum water gauge in less than or equal to 120 seconds. The licensee was performing this test as a post maintenance test following maintenance on the Unit 2 refueling floor vent exhaust fans inboard isolation damper, 2T41-F003A. At 04:05 the control room logs documented that the secondary containment drawdown test did not meet acceptance criteria and Technical Specification Required Action Statement 3.6.4.1.
Condition A was entered. The control room logs also documented that Required Action Statement 3.6.4.1 Condition A was exited at 05:57 because 2T41-F003A and 2T41-F023A, refueling floor vent exhaust fans discharge isolation dampers, had been deactivated/tagged out. SNC procedure NMP-AD-012, Operability Determination and Functionality Assessments, Ver. 12.3, is the procedure for determining and documenting the operability of systems, structures, or components when a degraded or non-conforming condition is found or suspected to exist. NMP-AD-012, Section 2.0.13, states, Technical specification operability considerations require that a system, structure, or component meet all surveillance requirements (as specified in Surveillance Requirement (SR) Applicability SR 3.0.1). A system, structure, or component that does not meet a surveillance requirement must be declared inoperable. Technical Specification Surveillance Requirement 3.0.1 states, Failure to meet a surveillance, whether such failure is experienced during the performance of the surveillance or between performance of the surveillances, shall be failure to meet the limiting condition for operability. With secondary containment failing to meet Surveillance Requirement 3.6.4.1.3 as documented in the most recent surveillance test, 34SV-T22-001-0, NMP-AD-012 required that secondary containment be declared inoperable. Hatch procedure 90AC-OAM-001-0, Test and Surveillance Control, Ver. 1.0, Section 5.2.10.4, contains actions following unsatisfactory surveillance testing results and states in part, To prove operability, a surveillance test shall be run on the equipment, system, or component as required by the surveillance requirement. Upon satisfactory completion of the surveillance test, operability will be declared. However, SNC senior reactor operators declared secondary containment operable without obtaining satisfactory surveillance test results for secondary containment following a failed secondary containment surveillance test.
Analysis:
Failure to prove operability following failure of a surveillance test as required by Hatch procedure 90AC-OAM-001-0, Test and Surveillance Control, Ver. 1.0, on May 12, 2014, was a performance deficiency. The performance deficiency affected the barrier integrity cornerstone and was more-than-minor because, if left uncorrected, it would have the potential to lead to a more significant safety concern. Specifically, declaring equipment operable following a failed surveillance test would have the potential for the facility to operate outside of technical specification requirements. 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 C of Exhibit 3, Barrier Integrity Screening Questions, because the finding only represented a degradation of the radiological barrier function provided by the standby gas treatment system. The inspectors determined the finding had a cross-cutting aspect of training in the human performance area, because the licensee did not ensure knowledge transfer of Surveillance Requirement 3.0.1 requirements to maintain a knowledgeable, technically competent workface and instill nuclear safety values. [H.9]
Enforcement:
10 CFR 50, Appendix B, Criterion V, Procedure, Drawings, and Instructions, requires in part that activities affecting quality shall be accomplished in accordance with documented instructions, procedures, or drawings, of a type appropriate to the circumstances. Hatch procedure NMP-AD-012, Operability Determination and Functionality Assessments, Ver. 12.3, Section 2.0.13 states in part, Technical specification operability considerations require that a system, structure, or component meet all surveillance requirements (as specified in Surveillance Requirement (SR) Applicability SR 3.0.1). A system, structure, or component that does not meet a surveillance requirement must be declared inoperable. In addition, Hatch procedure 90AC-OAM-001-0, Test and Surveillance Control, Ver. 1.0, Section 5.2.10.4, contains actions following unsatisfactory surveillance testing results and states in part, To prove operability, a surveillance test shall be run on the equipment, system, or component as required by the surveillance requirement. Upon satisfactory completion of the surveillance test, operability will be declared. Contrary to this requirement, on May 12, 2014, the licensee failed to accomplish an operability determination and failed to prove operability of secondary containment prior to declaring it operable. Specifically, senior reactor operators declared secondary containment operable after failing Surveillance Requirement 3.6.4.1.3 and did not prove operability by satisfactorily performing the surveillance test prior to declaring the secondary containment operable on May 12, 2014. To restore compliance, the licensee isolated the refueling floor dampers and re-performed Surveillance Requirement 3.6.4.1.3 with satisfactory results later that day on May 12, 2014. 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 CR 819563.

4OA2 Problem Identification and Resolution
.1 Routine Review
The inspectors screened items entered into the licensees corrective action program in order to identify repetitive equipment failures or specific human performance issues for follow-up. The inspectors reviewed condition reports, attended screening meetings, or accessed the licensees computerized corrective action database.
.2 Semi-Annual Trend Review
a. Inspection Scope
The inspectors reviewed issues entered in the licensees corrective action program and associated documents to identify trends that could indicate the existence of a more significant safety issue. The inspectors focused their review on repetitive equipment issues, but also considered the results of inspector daily condition report screenings, licensee trending efforts, and licensee human performance results. The review nominally considered the 6-month period of January 2014 through June 2014 although some examples extended beyond those dates when the scope of the trend warranted.
The inspectors compared their results with the licensees analysis of trends.
Additionally, the inspectors reviewed the adequacy of corrective actions associated with a sample of the issues identified in the licensees trend reports. The inspectors also reviewed corrective action documents that were processed by the licensee to identify potential adverse trends in the condition of structures, systems, and/or components as evidenced by acceptance of long-standing non-conforming or degraded conditions.
Documents reviewed are listed in the Attachment.

.2 (Closed) Temporary Instruction -2515/182 - Review of the Industry Initiative to Control
Degradation of Underground Piping and Tanks
a. Inspection Scope
From April 14 - April 16, 2014, the inspectors conducted a review of records and procedures related to the licensees program for buried pipe, underground pipe and tanks in accordance with Phase II of TI-2515/182. This review was done to confirm that the licensees program contained attributes consistent with Sections 3.3.A and 3.3.B of NEI 09-14 and to confirm that these attributes were scheduled and/or completed by the NEI 09-14 Revision 3 deadlines. To determine if the program attribute was accomplished in a manner which reflected good or poor practices in program management, the inspectors interviewed licensee staff responsible for the buried pipe program and reviewed buried pipe program related activities.
The licensees buried piping and underground piping and tanks program was inspected in accordance with paragraph 03.02.a of the temporary instruction (TI) and it was confirmed that activities, which correspond to completion dates specified in the program which have passed since the Phase 1 inspection was conducted, have been completed.
Additionally, the licensees buried piping and underground piping and tanks program was inspected in accordance with paragraph 03.02.b of the TI and responses to specific questions found in http://www.nrc.gov/reactors/operating/ops-experience/buried-pipe-ti-phase-2-insp-req-2011-11-16.pdf were submitted to the NRC headquarters staff.
Based upon the scope of the review described above, Phase II of TI-2515/182 was completed.
