SUMMARY
Watts Bar Nuclear Plant, Unit
This integrated inspection included aspects of engineering and construction activities performed by Tennessee Valley Authority (TVA) associated with the Watts Bar Nuclear (WBN) Plant Unit construction project. This report covered a one-month period of inspections in the areas of quality assurance (QA), identification and resolution of construction problems, engineering and construction activities, preoperational and startup testing, and follow-up of other activities. The inspection program for Unit construction activities is described in Nuclear Regulatory Commission (NRC) Inspection Manual Chapter (IMC) 2517, "Watts Bar Unit Construction Inspection Program." Information regarding the WBN Unit Construction Project and NRC inspections can be found at http://www.nrc.gov/info-finder/reactor/wb/watts-bar.html. Inspection Results
- The NRC identified a severity level (SL) IV non-cited violation (NCV) of Title of the Code of Federal Regulations (10 CFR) part 50, Appendix B, Criterion XVI, "Corrective Actions," for inadequate corrective actions of technical specification surveillances completed during preoperational testing. This performance deficiency was determined to be more than minor in accordance with IMC 2517, Appendix C, because the failure to properly identify and correct the problem to comply with licensing commitments, represented an improper work practice that could impact safety, involving safety-related structures, systems, and components. The inspectors determined this finding to be of very low safety significance, SL IV, in accordance with Section 6.5 of the Enforcement Policy because it represented a failure to meet a regulatory requirement, including one or more QA criteria that had more than minor safety significance; however, it did not represent a breakdown of the licensee's QA program. The licensee issued CR116812 to address the identified conditions. The inspectors determined that no cross-cutting aspect applied. (Section Q1.1)
- The NRC identified a SL IV NCV of CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the licensee's failure to follow procedures while obtaining chemistry samples of the chemical and volume control system (CVCS) and pressurizer liquid. This performance deficiency was determined to be more than minor, because it represented an improper or uncontrolled work practice that could impact quality or safety, involving safety-related structures, systems, and components. The inspectors determined this finding to be of very low safety significance, SL IV, in accordance with Section 6.5 of the Enforcement Policy because it represented a failure to meet a regulatory requirement, including one or more QA criteria that had more than minor safety significance; however, it did not represent a breakdown of the licensee's QA program. The violation was entered into the licensee's corrective action program as CR 1173643. The finding was assigned a cross-cutting aspect of Avoid Complacency in the Human Performance area as defined in NRC IMC 0310, because the licensee failed to recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes [H.12]. (Section SU 1.17)
- Other areas were inspected with no findings identified. These areas included QA; pre-operational testing activities; startup testing activities; and various NRC inspection procedures.

REPORT DETAILS
Summary of Plant Status
During the inspection period covered by this report, the Tennessee Valley Authority (TVA) performed construction completion as well as preoperational and startup testing activities on safety-related systems and continued engineering design activities of the Watts Bar Nuclear (WBN) Plant, Unit 2.
I. QUALITY ASSURANCE PROGRAM
Q.1.1 Identification and Resolution of Construction Problems (Inspection Procedure 35007)
a. Inspection Scope
The inspectors continued to review condition reports (CRs), as part of the licensee's corrective action program, to verify that issues being identified under the corrective action program were being properly identified, addressed, and resolved by the licensee.
The inspectors reviewed corrective actions for CR 1079639, initiated as a result of previous NRC inspections, to evaluate completion of Watts Bar Unit 2 tests and surveillances to ensure compliance with Title 10 of the Code of Federal Regulations (10 CFR) part 50.26 subpart I ("the Fatigue Rule"). The inspectors reviewed the corrective actions, to verify that the licensee: (1) adequately identified surveillances completed during hot functional and preoperational testing prior to fuel load; (2) performed a detailed review of all testing activities performed that would be credited towards technical specification operability requirements; (3) evaluated the surveillances that were performed by individuals not covered by the Fatigue Rule work hour limitations; and (4) reperformed technical specification surveillances that did not meet NRC requirements.
b. Observations and Findings
Introduction:
The inspectors identified a Severity Level (SL) IV non-cited violation (NCV) of 10 CFR part 50 (10 CFR 50), Appendix B, Criterion XVI, Corrective Actions,"
associated with the corrective actions with CR 1079639 to identify and correct issues regarding the licensee's evaluation of the Watts Bar Unit 2 tests and surveillances completed during preoperational testing to ensure compliance with the Fatigue Rule.
Description:
The inspection of CR 1079639 revealed that the licensee's intention was to (1) identify surveillances completed during hot functional and preoperational testing prior to fuel load; (2) perform a detailed review of all testing activities performed that would be credited towards technical specification operability requirements; (3) evaluate the surveillances that were performed by individuals not covered by the fatigue rule work hour limitations; and (4) reperform technical specification surveillances that did not meet NRC requirements. The licensee did perform a review of the testing activities performed prior to August 25, 2015 and noted that there were approximately 153 surveillances that were completed that did not meet the requirements of the Fatigue Rule. However, the licensee stated the surveillances were reviewed by a licensed senior reactor operator.
The CR was closed in December of 2015.
The inspectors determined that the licensee failed to adequately identify the entire population of surveillances completed during preoperational testing and did not implement the corrective actions to evaluate and or reperform surveillances to comply with the technical specification requirements which included the work hour fatigue rule. Specifically, (1) the licensee did not include all of the groups that completed surveillances during preoperational testing in the licensee's initial evaluation; (2) the licensee took credit for a senior reactor operator completing the technical specification operability review for meeting the requirements of the personnel completing the work to meet the work hour Fatigue Rule; and (3) the licensee did not evaluate or reperform the surveillances that were found to be performed by personnel that did not meet the work hour requirements, as specified by the corrective actions.
The licensee's failure to properly identify and correct the issues was a performance deficiency. This performance deficiency was determined to be more than minor in accordance with Inspection Manual Chapter (IMC) 2517, Appendix C, because the failure to properly identify and correct the problem of not complying with licensing commitments represented an improper work practice that could impact safety, involving safety-related structures, systems, and components. The inspectors determined this finding to be of very low safety significance,SL-IV, in accordance with Section 6.5 of the Enforcement Policy because it represented a failure to meet a regulatory requirement, including one or more quality assurance (QA) criteria that had more than minor safety significance; however, it did not represent a breakdown of the licensee's QA program.
The inspectors reviewed this finding against cross-cutting area components as described in IMC 0310 "Components Within the Cross-Cutting Areas" and determined that no cross-cutting aspect applied.
Enforcement:
10 CFR 50, Appendix B, Criterion XVI, "Corrective Action," requires, in part, that, "conditions adverse to quality are promptly identified and corrected."
CR 1079639 directed, in part, to identify surveillance tests performed during preoperational testing, prior to August 25, 2015, and evaluate if the surveillances were performed by individuals not covered by the Fatigue Rule work hour limitations. In addition, the corrective actions included reperforming surveillances that did not meet the requirements.
Contrary to the above, on December 31, 2015 the licensee closed the corrective actions and failed to identify all potential technical specification surveillances performed during preoperational testing and subsequently evaluate or reperform the surveillances that did not meet the Fatigue Rule work hour limitations.
Because this was a SL IV violation and it was entered into the licensee's corrective action program as CR 1168120, this violation is being treated as an NCV, consistent with Section 2.3.2 of the NRC Enforcement Policy. This violation is identified as NCV 05000391/2016605-01, "Inadequate Corrective Actions for technical specification surveillances completed during preoperational testing." c. Conclusion The inspectors identified an NCV associated with the inspection of the corrective actions associated with technical specification surveillances performed during preoperational testing the did not meet the work hour Fatigue Rule requirements. The licensee generated CR 1168120 to address the finding.
II. MANAGEMENT OVERSIGHT AND CONTROLS C.1 Construction Activities C.1.1 Unit 1 and Unit 2 Construction and Testing Activity Interface Controls
a. Inspection Scope
The inspectors independently assessed licensee controls, associated with Unit 2 testing activities, to prevent adverse impact on Unit 1 operational safety. The inspectors attended routine Unit 1/Unit 2 interface meetings to assess the exchange and sharing of information between the two site organizations. Periodic planning meetings were observed, at least once per week, to assess the adequacy of the licensee's efforts to identify those testing activities that could potentially impact the operating unit. This included the review of select testing activities, which the licensee had screened as not affecting Unit 1, to verify the adequacy of that screening effort. Additionally, the inspectors independently assessed select testing activities to verify that potential impacts on the operating unit had been identified and adequately characterized with appropriate management strategies planned for implementation. Furthermore, the inspectors performed independent walkdowns of select testing work locations to verify that controls to protect the operating unit provided an adequate level of protection and had been properly implemented.
b. Observations and Findings
No findings were identified.
c. Conclusions
Overall, management oversight and controls were in place for the observed preoperational tests and surveillance activities that could potentially impact the operating unit.
P.1 Preoperational Activities

b. Observations and Findings
Introduction:
The NRC identified a SL IV NCV of 10 CFR 50, Appendix B, Criterion V, "Instructions, Procedures, and Drawings," for the licensee's failure to follow procedures while obtaining chemistry samples of the CVCS and pressurizer liquid.
Description:
During the Watts Bar Nuclear Plant Unit 2 startup, the chemistry department was procedurally driven to obtain representative RCS samples at various times during the evolution. One aspect of this is to ensure that RCS boron concentrations are consistent with the operations requirements and that there is not an inappropriate boron concentration imbalance between the pressurizer and the RCS. To collect these samples, the licensee used procedure 2-CM-6.24, "Sampling CVCS Mixed Bed Demineralizers," Rev. 1, and procedure 2-CM-6.21, "Sampling The Pressurizer Liquid," Rev. 3.
On May 22, 2016, the inspectors observed the chemistry technician collect samples of the CVCS and pressurizer to be analyzed. After allowing the technician to complete the procedures, the inspector questioned the technician as to why the technician did not perform all of the steps in the procedures. Specifically, the technician did not perform section 6.3.3, step 1 of procedure 2-CM-6.24, which directed the adjustment of a pressure regulating valve to attain a sample flow of 8-14 gph, and did not perform section 6.3, step 1 of procedure 2-CM-6.21, which directed the adjustment of a pressure regulating vale to a sample flow of 8-10 gph. The inspector noted that on the completed procedures, the technician had circled and slashed the steps to indicate that they had been performed. Additionally, the inspector noted that the while the technician did not ensure that there were adequate sample flow rates, the flow rate for the pressurizer sample indicated 8 gph, which was acceptable, but the CVCS sample flow rate indicated 3 gph which was below the values required to proceed with the sample collection.
Upon confirmation that the procedures were not properly performed, the technician discarded the previously collected samples and collected and analyzed new samples in accordance with procedures. The issue was captured in the licensee's corrective action program as CR 1173643. Additionally, the licensee informed the inspector that the sample flow rates had been verified to be appropriate earlier in the shift. Through discussions with the licensee, the inspector noted the technician failed to consider how changing plant conditions may have led to the sample flow rates changing, but proper procedure use and adherence could have prevented the error.
The licensee's failure to follow procedures while obtaining chemistry samples of the CVCS and pressurizer liquid was determined to be a performance deficiency. The performance deficiency was more than minor, because it represented an improper or uncontrolled work practice that could impact quality or safety, involving safety-related structures, systems, and components. Specifically, not following the procedures for proper sampling of the CVCS and pressurizer could lead to a non-representative sample being used by plant operations. The inspectors determined this finding to be of very low safety significance, SL IV, in accordance with Section 6.5 of the NRC Enforcement Policy because it represented a failure to meet a regulatory requirement, including one or more QA criteria that had more than minor safety significance; however, it did not represent a breakdown of the licensee's QA program. The finding was assigned a cross-cutting aspect of Avoid Complacency in the Human Performance area as defined in NRC IMC 0310, because the licensee failed to recognize and plan for the possibility of mistakes, latent issues, and inherent risk, even while expecting successful outcomes
[H.12].
Enforcement:
Title 10 CFR Part 50, Appendix B, Criterion V, "Instructions, Procedures, And Drawings," required, in part, that "activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings." Contrary to the above, on May 22, 2016, the licensee failed to accomplish activities affecting quality in accordance with procedures. Specifically, the licensee failed to perform section 6.3.3, step 1 of procedure 2-CM-6.24, and failed to perform section 6.3, step 1 of procedure 2-CM-6.21. This violation is being treated as an NCV consistent with Section 2.3.2 of the Enforcement Policy. The violation was entered into the licensee's corrective action program as CR 1173643 and the licensee collected and analyzed additional CVCS and pressurizer samples. (NCV 05000391/2016605-02, "Failure to Follow Procedures For Collecting Chemistry Samples.")
c. Conclusions
With the exception of the inspection finding described above, the inspectors determined that the licensee's power escalation test was performed in a manner consistent with the guidance of procedure 2-TI-438, "Watts Bar Nuclear Plant Unit 2 Power Ascension Test Program," Rev. 5. This completes the witnessing of power escalation test procedure 2-PET-201.
