SUMMARY
The U.S. Nuclear Regulatory Commission (NRC) continued monitoring the licensees performance by conducting an integrated inspection at Comanche Peak Nuclear Power Plant,
Units 1 and 2, in accordance with the Reactor Oversight Process. The Reactor Oversight Process is the NRCs program for overseeing the safe operation of commercial nuclear power reactors. Refer to https://www.nrc.gov/reactors/operating/oversight.html for more information.
Findings and violations being considered in the NRCs assessment are summarized in the table below.
List of Findings and Violations Failure to Identify and Correct a Condition Adverse to Quality Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green H.11 - Human 71152 Systems NCV 05000445/2018002-01; Performance, Problem 05000446/2018002-01 Challenge the Identification Closed Unknown and Resolution The inspectors identified a Green, non-cited violation of 10 CFR 50, Appendix B, Criterion XVI,
Corrective Action, associated with the licensees failure to identify and correct a condition adverse to quality associated with unacceptable main steam isolation valve (MSIV) stroke times. Specifically, during stroke time testing of MSIV 2-02 the valves stroke time was outside of the acceptance limit and the licensee failed to determine why the stroke time was out of specification and correct the issue prior to declaring the valve operable and placing it in service.
The licensee entered this issue into the corrective action program as Condition Report CR-2018-002189.
Unacceptable Preconditioning of Main Steam Isolation Valves Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green H.7 - Human 71152 Systems NCV 05000445/2018002-02; Performance, Problem 05000446/2018002-02 Documentation Identification Closed and Resolution The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XI,
Test Controls, for the licensees unacceptable preconditioning of the Unit 1 main steam isolations valves (MSIV) prior to performing as-found in-service stroke time testing.
Specifically, the licensee raised accumulator pressure prior to stroke time testing and this potentially masked an issue with MSIV 1-01. The licensee entered this issue into the corrective action program as Condition Report CR-2018-002405.
Failure to Incorporate Design Information Into System Test Procedures Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green None 71152 Systems NCV 05000445/2018002-03; Problem 05000446/2018002-03 Identification Closed and Resolution The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XI,
Test Controls, for the licensees failure to ensure that the stations in-service testing program for main steam isolation valves (MSIVs) incorporated the requirements and acceptance limits contained in applicable design documents. Specifically, the licensees in-service procedures did not direct testing of the valves be performed at the minimum required pressure and this resulted in the licensees failure to identify two degraded MSIVs during in-service testing. The licensee entered this issue into the corrective action program as Condition Report CR-2018-003229.

INSPECTION RESULTS
Failure to Identify and Correct a Condition Adverse to Quality Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green H.11 - Human 71152 Systems NCV 05000445/2018002-01; Performance, Problem 05000446/2018002-01 Challenge the Identification Closed Unknown and Resolution The inspectors identified a Green, non-cited violation of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, associated with the licensees failure to identify and correct a condition adverse to quality associated with unacceptable main steam isolation valve (MSIV)stroke times. Specifically, during stroke time testing of MSIV 2-02, the valves stroke time was outside of the acceptance limit, and the licensee failed to determine why the stroke time was out of specification and correct the issue prior to declaring the valve operable and placing it in service.
Description:
While reviewing work and testing history for MSIVs, inspectors reviewed CR-2017-005973. This condition report was written to document the need for a preconditioning evaluation. Specifically, operators wrote that during stroke time testing of the Unit 2 MSIVs in accordance with station Procedure OPT-509B, MSIV Testing, all nitrogen accumulator pressures were out of specification low before testing resulting in unsatisfactory data on all MSIVs. Additionally, the licensees staff documented that MSIV 2-02 had an unsatisfactory stroke time test of 5.08 seconds (acceptance criteria of less than or equal to 5 seconds). Operations personnel had raised accumulator pressures and re-performed stroke time testing and MSIV 2-02 passed with a time of 4.46 seconds. Operations personnel subsequently determined that only MSIV 2-02 required evaluation because all other valves had passed prior to raising pressure.
Station engineering determined that raising the pressure from 1930 psig to 2140 psig in the accumulator for MSIV 2-02 was unacceptable preconditioning and the subsequent stroke time testing was not valid. Engineering subsequently determined that since the actuator for MSIV 2-02 was replaced with a rebuilt spare actuator during refueling outage 2RF16 that maintenance had caused the change in stroke time and the corrective action for this was to adjust the flow control valve setting for the actuator which would reduce stroke time.
Inspectors determined that the MSIV function is to close in less than or equal to 5 seconds to terminate steam flow from unaffected steam generators during a steam line break. In order to generate the force necessary to shut the valves in the specified time, the installed nitrogen accumulators require nitrogen pressure to be a minimum of 1839 psig. Inspectors noted that the initial stroke performed on MSIV 2-02 occurred with an accumulator pressure of 1930 psig and the stroke time of 5.08 seconds. Operators then raised pressure to 2140 psig and the valve stroked in 4.46 seconds and following adjustment of the flow control the licensee had stroked MSIV 2-02 twice more and valve stroke times did not improve (4.54 and 4.46 seconds).
Based on this, inspectors questioned the operability of MSIV 2-02 and engineerings determination of maintenance being the cause of the slow stroke time. Specifically, the actuator had been rebuilt and tested by a vendor, the site had not performed any maintenance on the actuator, and the flow control valve adjustment had not changed stroke speed. Inspectors informed the licensee of their concerns and the licensee initiated Condition Report CR-2018-002189 to address these concerns.
The licensee subsequently determined that MSIV 2-02 would most likely not close in the required time with accumulator pressure at 1839 psig and performed an operability evaluation which determined that the valve was operable but degraded, and required accumulator pressure be maintained by procedure at 1962 psig or above. The licensee also determined that the causes of the slow stroke time were
- (1) that the valve actuator had been setup using an accumulator pressure greater than 1839 psig, and
- (2) vendor and site post work testing procedures were inadequate to detect the improper setup.
During extent of condition reviews the licensee determined that MSIV 1-01 also would not close in the required time at 1839 psig. The licensee performed an operability evaluation which determined that the valve was operable but degraded and required accumulator pressure be maintained by procedure at 1997 psig or above.
Corrective Action(s): The licensee performed an operability determination that established a reasonable expectation of operability for the two MSIVs pending development of additional corrective actions. While the licensee continues to assess how to correct the condition that caused the valves to be unable to meet the stroke time requirement, the licensee has implemented acceptable compensatory measures to assure the valves remain operable.
Corrective Action Reference(s): CR-2018-002189
Performance Assessment:
Performance Deficiency: The licensees failure to identify and correct a condition adverse to quality was a performance deficiency.
Screening: The inspectors determined the performance deficiency was more than minor because it adversely affected 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, the failure to identify and correct the cause of the slow stroke time resulted in unidentified degraded equipment being placed in service.
Significance: The inspectors assessed the significance of the finding using Inspection Manual Chapter 0609, Attachment 04, Initial Characterization of Findings, dated October 7, 2016, and Inspection Manual Chapter 0609, Appendix A, Significance Determination Process for Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, and determined the finding was of very low safety significance (Green) because:
- (1) it was not a design deficiency;
- (2) it did not represent a loss of system and/or function; (3)it did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time; and
- (4) it did not result in the loss of a high safety significant non-technical specification train.
Cross-cutting Aspect: The finding has a cross-cutting aspect in the area of human performance, challenge the unknown, because the licensee did not stop when faced with uncertain conditions following the failed stoke time test of MSIV 2-02 [H.11].
Enforcement:
Violation: Title 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, requires, 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 and corrected.
Contrary to the above, from May 23, 2017 through present, the licensee failed to promptly identify and correct a condition adverse to quality associated with improper stroke time of MSIV 2-02. Specifically, during stroke time testing of MSIV 2-02, the valves stroke time was outside of the acceptance limit, and the licensee failed to determine why the stroke time was out of specification and correct the issue prior to declaring the valve operable and placing it in service.
Disposition: This violation is being treated as a Non-Cited Violation, consistent with Section 2.3.2 of the Enforcement Policy.
Unacceptable Preconditioning of Main Steam Isolation Valves Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green H.7 - Human 71152 Systems NCV 05000445/2018002-02; Performance, Problem 05000446/2018002-02 Documentation Identification Closed and Resolution The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XI, Test Controls, for the licensees unacceptable preconditioning of the Unit 1 main steam isolations valves (MSIV) prior to performing as-found in-service stroke time testing.
Specifically, the licensee raised accumulator pressure prior to stroke time testing and this masked an issue with MSIV 1-01.
Description:
During their review of information described in NCV 05000445/2018002-01; 5000446/2018002-01 (above), inspectors noted that the licensee had performed a procedure change that would allow for preconditioning of MSIVs. Specifically, Condition Report CR-2017-005973 was written to document the need for a preconditioning evaluation because operators had thought that during stroke time testing of the Unit 2 MSIVs per station Procedure OPT-509B, MSIV Testing, all nitrogen accumulator pressures were low out of specification. This condition report closed an action to CR-2017-006304, which changed Procedure OPT-509B, MSIV Testing, and added a prerequisite step to charge the valves accumulators in accordance with procedure MSM-C0-6856, MSIV Accumulator Hemisphere Charging, prior to testing. Inspectors also noted that the licensee had used this revised procedure when stroke time testing the Unit 1 MSIVs on November 10, 2017.
Inspectors reviewed procedure MSM-C0-6856 and determined that, regardless of as found pressure, this procedure directed the accumulators be charged to the high end of the log limit (approximately 2140 psig). Inspectors noted that MSIV function is to close in less than or equal to 5 seconds to terminate steam flow from unaffected steam generators during a steam line break, and in order to generate the force necessary to shut the valves in the specified time the installed nitrogen accumulators require nitrogen pressure to be a minimum of 1839 psig.
Inspectors questioned whether this procedure change to charge the accumulators before testing constituted unacceptable preconditioning. Inspectors reviewed Inspection Manual Technical Guidance Part 9900, Maintenance - Preconditioning of Structures, Systems, and Components Before Determining Operability, and noted that this defines preconditioning, in part, as:
The alteration, variation, manipulation, or adjustment of physical condition of an SSC
[structure, system, or component] before or during Technical Specification surveillance or ASME code testing.
The technical guidance also defines unacceptable preconditioning, in part, as:
The alteration, variation, manipulation, or adjustment of physical condition of an SSC before or during Technical Specification surveillance or ASME code testing that will alter one or more of an SSCs operational parameters, which results in acceptable test results. Such changes could mask the actual as-found condition of the SSC and possibly result in an inability to verify the operability of the SSC. In addition, unacceptable preconditioning could make it difficult to determine whether the SSC would perform its intended function during an event in which the SSC might be needed.
Technical Guidance Part 9900 further describes that some types of preconditioning may be considered acceptable, but that, this preconditioning should have been evaluated and documented in advance of the surveillance.
Inspectors informed the licensee of their concerns and the licensee initiated Condition Report CR-2018-002405 to capture this concern in the stations corrective action program. During discussion, inspectors determined that the licensee had not evaluated the procedure change for the potential to precondition the MSIVs. Instead the licensee was focused on ensuring that the accumulators pressures were within log limits prior to testing because that was the pressure band at which they were normally operated. Inspectors questioned this logic because increasing pressure would result in the valve stroking faster. During conversations with the actuator vendor, the licensee discovered that raising pressure in the accumulator did in fact affect stroke time. Specifically, the vendor informed the licensee that a 300 psig increase resulted in an approximate speed increase of 0.15 seconds.
Based on this information, the inspectors determined that the licensees procedure change would unacceptably precondition the MSIVs. Specifically, raising accumulator pressure could help the valves pass in-service testing while masking degraded conditions that would prevent the valves from performing their intended function during an event.
During extent of condition reviews for NCV 05000445/2018002-01; 5000446/2018002-01 the licensee determined that MSIV 1-01 would not close in the required time at 1839 psig. The licensee performed an operability evaluation which determined that the valve was operable but degraded and required accumulator pressure be maintained by procedure at 1997 psig or above.
Corrective Action(s): The licensee performed an operability determination that established a reasonable expectation of operability pending development of additional corrective actions.
Corrective Action Reference(s): CR-2018-002189; CR-2018-002405
Performance Assessment:
Performance Deficiency: The licensees unacceptable preconditioning of the Unit 1 main steam isolation valves was a performance deficiency.
Screening: The inspectors determined the performance deficiency was more than minor because it adversely affected 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, the licensee raised accumulator pressure prior to stroke time testing, which potentially masked a degraded condition with MSIV 1-01.
Significance: The inspectors assessed the significance of the finding using Inspection Manual Chapter 0609, Attachment 04, Initial Characterization of Findings, dated October 7, 2016, and Inspection Manual Chapter 0609, Appendix A, Significance Determination Process for Findings At-Power, Exhibit 2, Mitigating Systems Screening Questions, and determined the finding was of very low safety significance (Green) because:
- (1) it was not a design deficiency;
- (2) it did not represent a loss of system and/or function; (3)it did not represent an actual loss of function of at least a single train for longer than its technical specification allowed outage time; and
- (4) it did not result in the loss of a high safety significant non-technical specification train.
Cross-cutting Aspect: The finding has a cross-cutting aspect in the area of human performance, documentation, because the licensee failed to maintain accurate documentation for MSIV in-service testing which contributed to the performance deficiency [H.7].
Enforcement:
Violation: Title 10 CFR Part 50, Appendix B, Criterion XI, Test Control, requires, in part, that a test program shall be established to assure that all testing required to demonstrate components will perform satisfactorily in service is identified and performed in accordance with written procedures which incorporate the requirements and acceptance limits contained in applicable design documents.
Contrary to the above, on November 10, 2017, the licensee failed to establish a test program to assure that all testing required to demonstrate components will perform satisfactorily in service is identified and performed in accordance with written procedures which incorporate the requirements and acceptance limits contained in applicable design documents.
Specifically, the licensee unacceptably preconditioned the Unit 1 main steam isolation valves prior to conducting as-found in-service stroke time testing.
Disposition: This violation is being treated as a Non-Cited Violation, consistent with Section 2.3.2 of the Enforcement Policy.
Failure to Incorporate Design Information Into System Test Procedures Cornerstone Significance Cross-cutting Report Aspect Section Mitigating Green Not assigned 71152 Systems NCV 05000445/2018002-03; Problem 05000446/2018002-03 Identification Closed and Resolution The inspectors identified a non-cited violation of 10 CFR Part 50, Appendix B, Criterion XI, Test Controls, for the licensees failure to ensure that the stations in-service testing program for MSIVs incorporated the requirements and acceptance limits contained in applicable design documents. Specifically, the licensees in-service procedures did not direct testing of the valves be performed at the minimum required pressure, and this resulted in the licensees failure to identify two degraded MSIVs during in-service testing.
Description:
During their review of information described in NCVs05000445/2018002-01; 5000446/2018002-01 and 05000445/2018002-02; 5000446/2018002-02, inspectors noted that the licensee had failed to incorporate all relevant design information into the MSIV in-service testing program. Specifically, the licensees in-service test program only contained a timing requirement for the MSIVs (less than or equal to 5 seconds to close) but did not specify a corresponding pressure requirement for this closing time.
Inspectors had determined that the MSIV function is to close in less than or equal to 5 seconds to terminate steam flow from unaffected steam generators during a steam line break.
In order to generate the force necessary to shut the valves in the specified time the installed nitrogen accumulators require nitrogen pressure to be a minimum of 1839 psig, and raising accumulators above the minimum required pressure resulted in faster closing time of the valves. Raising pressure in the accumulator 300 psig increases stroke speed by approximately 0.15 seconds. However, the licensee was not stroke time testing the valves at the minimum pressure, nor did they establish a correlation for pressure versus stroke time for the pressures the valves were tested.
The inspectors determined that the inadequate in-service testing procedures resulted in the licensees failure to identify degraded conditions with MSIVs 1-01 and 2-02 (discussed in NCVs05000445/2018002-01; 5000446/2018002-01 and 05000445/2018002-02; 5000446/2018002-02).
Inspectors informed the licensee of their concerns and the licensee initiated Condition Report CR-2018-003229. Through discussions with the licensee inspectors determined that in 2000 testing requirements were changed and the requirements to test the valves at 1839 psig was removed. The licensee determined that the change to the testing methodology was a result of the vendor changing their test procedures for how they tested the actuators.
Corrective Action(s): The licensee performed operability determinations that established a reasonable expectation of operability for the MSIVs pending development of additional corrective actions.
Corrective Action Reference(s): CR-2018-003229
Performance Assessment:
Performance Deficiency: The licensees failure to ensure that the stations in-service testing program for MSIVs incorporated the requirements and acceptance limits contained in applicable design documents was a performance deficiency.

Cross-cutting Aspect: The finding was not assigned a cross-cutting aspect because the finding was not indicative of present performance.
Enforcement:
Violation: Title 10 CFR Part 50, Appendix B, Criterion XI, Test Control, requires, in part, that a test program shall be established to assure that all testing required to demonstrate components will perform satisfactorily in service is identified and performed in accordance with written procedures which incorporate the requirements and acceptance limits contained in applicable design documents.
Contrary to the above, from 2000 until present, the licensee failed to establish a test program to assure that all testing required to demonstrate components will perform satisfactorily in service is identified and performed in accordance with written procedures, which incorporate the requirements, and acceptance limits contained in applicable design documents.
Specifically, the licensee failed to ensure that the stations in-service testing program for MSIVs incorporated the requirements and acceptance limits contained in applicable design documents Disposition: This violation is being treated as a Non-Cited Violation, consistent with Section 2.3.2 of the Enforcement Policy.
Failure to Follow the Sites Dry Cask Storage Project Foreign Material Exclusion Plan Inside a High Risk FME Zone Cornerstone Significance Cross-cutting Report Aspect Section Other Severity Level IV Not Applicable 60855.1 NCV 07200074/2018001-01 Closed The inspectors identified a Severity Level IV, non-cited violation (NCV) of 10 CFR 72.150, Instructions, Procedures, and Drawings, for the licensee's failure to establish an foreign material exclusion (FME) monitor and an FME log during certain dry fuel storage evolutions, as required by site procedures.
Description:
On May 15, 2018, the licensee's contract group for dry fuel storage (DFS)operations, Holtec International, was in the process of performing a crane lift for moving a HI-TRAC transfer cask containing a loaded MPC-32 canister from the Unit-1/2 spent fuel pool (SFP) to the dry cask pit location for decontamination and MPC lid-to-shell welding. This cask movement is described in the Comanche Peak Nuclear Power Plant (CPNPP) Dry Cask Storage Procedure Manual as an FME High Risk Activity. Section 4.6.3 of the licensees Dry Cask Storage Project FME Plan (FME Plan) states that once [the High Risk FME zone is]
established, a trained FME monitor will be required to control logging and inspecting of any material or tools before it is allowed to be taken [into] an FME Zone. The inspectors noted High Risk FME Zone signage on an area platform a few levels above the location of the dry cask pit. However, once the HI-TRAC/MPC was set down in the dry cask pit, welders were observed entering and exiting the High Risk FME Zone without the presence of a FME monitor. When questioned by the NRC inspector, the welders were not knowledgeable of the FME exclusion zone requirements, the requirement for an FME monitor, or the location the FME log.
The NRC inspectors also noted a general absence of licensee presence to provide contractor oversight during key DFS loading operations. The NRC inspectors attributed the lack of site procedure adherence to the sites FME Plan to the licensees poor oversight during DFS activities. The CPNPP Dry Cask Storage Project FME Plan is a licensee procedure. The contractors should have been adequately trained on the sites FME Plan and been compliant with the sites procedures. The NRC inspectors identified the contactors non-compliance with site procedures on the sixth canister of a seven canister campaign. It was identified that both the welding contractors and the Holtec loading contractors were unaware of the sites FME Plan procedural requirements.
Corrective Action(s): The licensee assigned an individual to the role of FME monitor and established a current FME log as required by site procedures. The condition was entered into the licensees corrective action program.
Corrective Action Reference(s): CR-2018-003509
Performance Assessment:
Not applicable to traditional enforcement findings.
Enforcement:
Severity: Dry fuel storage operations are governed by the regulations of 10 CFR 72. Part 72 regulations are dispositioned using traditional enforcement. This violation was more than minor because the non-compliance, if allowed to continue, could have created the potential for a more than minor safety consequence if left uncorrected.
Violation: 10 CFR 72.150, Instructions, Procedures, and Drawings, states, in part, that activities affecting quality shall be prescribed by documented procedures and shall be accomplished in accordance with these procedures. Procedures shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been accomplished.
Comanche Peak Procedure DCS-100, Dry Fuel Storage Campaign Guidelines, 10.1.8, Dry Cask Storage Project FME Plan, established that movement of a loaded HI-TRAC to the dry cask pit and MPC lid-to-shell welding while in the dry cask pit were FME High Risk Activities. Further the FME Plan stated that the fuel building High Risk FME Zone for Dry Cask Operations and the dedicated FME monitor will be established just prior
[to] commencing fuel building [dry cask storage] operations and will remain in effect until placement of the HI-STORM overpack lid is made on the last loaded MPC of the campaign following stackup and all FME logs have been balanced.
Contrary to the above requirements, on May 15, 2018, the licensee failed to accomplish activities affecting quality in accordance with licensee procedure DCS-100. Specifically, the position of FME monitor was not staffed during FME High Risk Activities, as required by the site FME Plan. Further, when questioned, the licensee could not produce any quantitative or qualitative evidence that the contractors followed the sites FME Plan during the FME high risk activities for the five previously loaded MPCs dating back to the beginning of the DFS campaign in early April 2018.
Disposition: Because this violation was not repetitive or willful, and was entered into the licensees corrective action program as CR-2018-003509, this violation is being treated as a Non-Cited Violation (NCV), consistent with Section 2.3.2 of the Enforcement Policy.
Observation Report Section 71152 NCV 05000445/2017003-02; 05000446/2017003-02, Programmatic Failures to Control Transient Combustible Material in Accordance with a Fire Protection Procedure, documents programmatic failures by the licensee to Implement controls of transient combustible materials. Inspectors reviewed the licensees program to date to determine what corrective actions were implemented and if these actions were correcting the issue. Inspectors determined that the licensees actions were not having the desired effect. Specifically, inspectors identified multiple minor examples where transient combustibles were being stored in Group B storage areas without proper controls. This was determined to be due to lack of station supervision engagement with regard to procedural compliance. Inspectors determined that initially station management focused heavily on transient combustible controls but over time this focus shifted to other areas, and as a result, station compliance with transient combustible controls degraded. Inspectors shared their observations with the licensee who in turn implemented new actions to address the identified program shortcomings.
